The Euro – A Monetary Strangulation Mechanism

In my previous post I claimed that the ‘Greek crisis’ essentially is not about Greece, but rather that the crisis is a symptom of a bigger problem namely the euro itself.

Furthermore, I claimed that had it not been for the euro we would not have had to have massive bailouts of countries and we would not have been in a seven years of recession in the euro zone and unemployment would have been (much) lower if we had had floating exchange rates in across Europe instead of what we could call the Monetary Strangulation Mechanism (MSM).

It is of course impossible to say how the world would have looked had we had floating exchange rates instead of the MSM. However, luckily not all countries in Europe have joined the euro and the economic performance of these countries might give us a hint about how things could have been if we had never introduced the euro.

So I have looked at the growth performance of the euro countries as well as on the European countries, which have had floating (or quasi-floating) exchange rates to compare ‘peggers’ with ‘floaters’.

My sample is the euro countries and the countries with fixed exchange rates against the euro (Bulgaria and Denmark) and countries with floating exchange rates in the EU – the UK, Sweden, Poland, Hungary, the Czech Republic and Romania. Furthermore, I have included Switzerland as well as the EEA countriesNorway and Iceland (all with floating exchange rates). Finally I have included Greece’s neighbour Turkey, which also has a floating exchange rate.

In all 31 European countries – all very different. Some countries are political dysfunctional and struggling with corruption (for example Romania or Turkey), while others are normally seen as relatively efficient economies with well-functioning labour and product markets and strong external balance and sound public finances like Denmark, Finland and the Netherland.

Overall we can differentiate between two groups of countries – euro countries and euro peggers (the ‘red countries’) and the countries with more or less floating exchange rates (the ‘green countries’).

The graph below shows the growth performance for these two groups of European countries in the period from 2007 (the year prior to the crisis hit) to 2015.

floaters peggers RGDP20072015 A

The difference is striking – among the 21 euro countries (including the two euro peggers) nearly half (10) of the countries today have lower real GDP levels than in 2007, while all of the floaters today have higher real GDP levels than in 2007.

Even Iceland, which had a major banking collapse in 2008 and the always politically dysfunctionally and highly indebted Hungary (both with floating exchange rates) have outgrown the majority of euro countries (and euro peggers).

In fact these two countries – the two slowest growing floaters – have outgrown the Netherlands, Denmark and Finland – countries which are always seen as examples of reform-oriented countries with über prudent policies and strong external balances and healthy public finances.

If we look at a simple median of the growth rates of real GDP from 2007 until 2015 the floaters have significantly outgrown the euro countries by a factor of five (7.9% versus 1.5%). Even if we disregard the three fastest floaters (Turkey, Romania and Poland) the floaters still massively outperform the euro countries (6.5% versus 1.5%).

The crisis would have long been over had the euro not been introduced  

To me there can be no doubt – the massive growth outperformance for floaters relative to the euro countries is no coincidence. The euro has been a Monetary Strangulation Mechanism and had we not had the euro the crisis in Europe would likely long ago have been over. In fact the crisis is essentially over for most of the ‘floaters’.

We can debate why the euro has been such a growth killing machine – and I will look closer into that in coming posts – but there is no doubt that the crisis in Europe today has been caused by the euro itself rather than the mismanagement of individual economies.

PS I am not claiming the structural factors are not important and I do not claim that all of the floaters have had great monetary policies. The only thing I claim is the the main factor for the underperformance of the euro countries is the euro itself.

PPS one could argue that the German ‘D-mark’ is freely floating and all other euro countries essentially are pegged to the ‘D-mark’ and that this is the reason for Germany’s significant growth outperformance relative to most of the other euro countries.

Update: With this post I have tried to demonstrate that the euro does not allow nominal adjustments for individual euro countries and asymmetrical shocks therefore will have negative effects. I am not making an argument about the long-term growth outlook for individual euro countries and I am not arguing that the euro zone forever will be doomed to low growth. The focus is on how the euro area has coped with the 2008 shock and the the aftermath. However, some have asked how my graph would look if you go back to 2000. Tim Lee has done the work for me – and you will see it doesn’t make much of a difference to the overall results. See here.

Update II: The euro is not only a Monetary Strangulation Mechanism, but also a Fiscal Strangulation Mechanism.

Leszek Balcerowicz on Poland’s success and Christensen on Balcerowicz’s success

For the past soon 15 year I have followed the economic development in Poland very closely and have visited the country very often. I have come to love the country and the Poles so I rejoice these days as Poland celebrates the 25 year anniversary of Poland’s first (partly) free election on June 4 1989. The democratic revolution opened the floodgates for free market reforms across the former communist countries in Central and Eastern Europe.

The main architect of the Polish reforms, which have led to a remarkable economic success over the past 25 years was Leszek Balcerowicz. Balcerowicz is one of my absolut biggest heroes. A great economist and a true reformer. Poles have a lot to thank Leszek Balcerowicz for. If anybody symbolizes the successful transition from communist dictatorship to free market democracy in Poland it is Leszek Balcerowicz.

Balcerowicz has a very good piece on Polish success story on

I really feel like quoting the whole thing. But here is just a piece of it:

How does one explain these and other differences in economic performance after socialism, including the relative success of Poland? First, the quicker and more radical the improvement in the economic system – if sustained – the faster the long-term economic growth.

An early “Big Bang”, pioneered by Poland in 1990, and implemented even more radically by Estonia, has proved much better than delayed, slow or inconsistent reforms. For example, Poland introduced the convertibility of the currency as part of a large package of liberalisation and stabilisation measures less than four months from the start of its new government, while in Ukraine it took almost four years.

What kind of capitalism emerges is vital. In Poland (and most other CEE countries) the success of private groups does not depend, as a rule, on their political and bureaucratic connections, while in Russia or Ukraine this has been crucial.

Politicised or crony capitalism is not only unfair but inefficient, as it stifles economic competition and generates huge rent-seeking activity. Equal treatment is not only a matter of ethics but of efficiency.

Second, fiscal stance matters for growth. One reason for Hungary’s poor record has been the size of its government, coupled with persistent deficits, occasional fiscal crises and huge public debt. Poland’s fiscal situation has been far from ideal, but not as bad as Hungary’s.

Third, longer-term economic growth slows down when countries suffer deep recessions – a result of external shocks, boom-bust policies (Baltics, Bulgaria, Ukraine) or of the misallocation of credit by the dominant state banks (Slovenia).

Uniquely among post-socialist economies, Poland had no recession after 1989. A boom-bust pattern was avoided by relatively prudent monetary and supervisory policies while politicised misallocation of credit was avoided due to a surge in bank privatisation during 1998-2000.

Great stuff!

By the way this is what I wrote about Balcerowicz when he stepped down as central bank governor in 2007:

“Balcerowicz musi odejsc” (“Balcerowicz must go”). This was the all-too-familiar demand made by the populist Polish politician Andrzej Lepper when the outgoing Polish central bank governor Leszek Balcerowicz was Polish Finance Minister in the early 90s. Mr Lepper’s wish is to some extent now finally being fulfilled, as Mr. Balcerowicz steps down today after six successful years as central bank governor.

Mr. Balcerowicz has always been a controversial figure in Polish policymaking, but no one can dispute his enormous influence in the past 20 years – first as an economic advisor within the independent labour union Solidarność and participant in the roundtable negotiations that in 1989 led to the end of communist rule in Poland. As the first Finance Minister in post-communist Poland, from September 1989 to August 1991, Mr. Balcerowicz used what he has called a window of opportunity to implement the plan named after him – the Balcerowicz Plan – to transform Poland from an inefficient planned economy to a market economy. The Balcerowicz Plan was the first example of shock therapy being applied in the former communist countries in Central and Eastern Europe, and in our view there is no doubt that the reforms Mr. Balcerowicz engineered are one of the key reasons for Poland’s economic success over the last 18 years. Mr. Balcerowicz later continued the reform effort as Finance Minister once more from October 1997 to June 2000.

From December 2000 until today Mr. Balcerowicz has been governor of the Polish central bank (NBP). As NBP governor he has shown himself as a strong anti-inflationist central banker who has fearlessly defended the independence of the NBP from numerous unfortunate political attacks. The best measure of a central banker’s success is undoubtedly is the development in inflation, and here there is no doubt about Mr. Balcerowicz’s achievements. From December 2000 to November 2006, inflation in Poland dropped from 8.5% to 1.4% y/y – clearly something that Mr. Balcerowicz and his colleagues at the NBP can be proud of. Obviously there have also been policy mistakes over the last six years at the NBP. Some would, for example, argue that the NBP took far too long to ease monetary policy and this helped to push the Polish economy into a massive slowdown in 2001-2003. On the other hand, the NBP’s conservative approach to monetary policy during Mr. Balcerowicz’s rule has opened the door to a much more sustainable recovery in the Polish economy than would otherwise have been the case. It, of course, should also be noted that Mr. Balcerowicz’s term as NBP governor was to a minor degree tainted by fairly bad communication policies – that to some extent reflected internal disagreement at times within the NBP’s monetary policy council.

We say goodbye and thanks to Mr. Balcerowicz, but we don’t believe the charismatic liberal economist will be silenced and we expect – and hope – that Mr. Balcerowicz will continue to engage in the debate on economic policy in Poland in the coming years. Poland surely needs his input.

Luckily Leszek Balcerowicz has not been silenced and he has continued to call for further economic reforms in Poland so the success of the past 25 years can be continued.

This is Balcorwicz’s suggestions for reform in Poland – also from his FT-piece:

However, past success can be a poor predictor of performances, and Poland is not immune to this rule. Indeed, without additional reforms, Poland’s economic growth will slow considerably.

There are three reasons for this. First, the ageing population would reduce employment and increase the share of older, non-employed people. Second, Poland’s private investment ratio is the lowest in the region, along with that of Hungary. Third, the growth of overall efficiency (as measured by total factor productivity – TFP) which has been a main driver of Poland’s economic success, has slowed considerably in recent years.

These negative tendencies could be neutralised by further reforms. For example, Poland could considerably increase employment of younger and older people.

The gradual increase in the retirement age to 67 was a step in the right direction. But more has to be done – for example stopping and reversing the rise in the mandatory minimum wage.

Private investment could be raised by the elimination of various regulatory or bureaucratic barriers to investment and by increasing the savings ratio. Unfortunately, the de facto confiscation of the mandatory retirement savings enacted in 2013 was a step in the wrong direction.

I fully agree with Balcerowicz’s analysis and policy recommendations. Further deep structural reforms are certainly needed in Poland if the success of the past 25 years should be continued. But I am also hopeful that the great Polish people understands this.Congratulation to my beloved Poland with 25 years’ freedom and economic success.

Echoes from the past – how Molotov declared war on Poland in 1939

I got this from Erwan Mahé‘s excellent newsletter Thaler’s Corner:

September 17, 1939

Mr. Ambassador!

The Polish-German War has revealed the internal bankruptcy of the Polish State. During the course of ten days’ hostilities Poland has lost all her industrial areas and cultural centres. Warsaw, as the capital of Poland, no longer exists. The Polish Government has disintegrated, and no longer shows any sign of life. This means that the Polish State and its Government have, in point of fact, ceased to exist. In the same way, the Agreements concluded between the U.S.S.R. and Poland have ceased to operate. Left to her own devices and bereft of leadership, Poland has become a suitable field for all manner of hazards and surprises, which may constitute a threat to the U.S.S.R. For these reasons the Soviet Government, who have hitherto been neutral, cannot any longer preserve a neutral attitude towards these facts.

The Soviet Government also cannot view with indifference the fact that the kindred Ukrainian and White Russian people, who live on Polish territory and who are at the mercy of fate, should be left defenceless.

In these circumstances, the Soviet Government have directed the High Command of the Red Army to order the troops to cross the frontier and to take under their protection the life and property of the population of Western Ukraine and Western White Russia.

At the same time the Soviet Government propose to take all measures to extricate the Polish people from the unfortunate war into which they were dragged by their unwise leaders, and enable them to live a peaceful life.

Accept, Mister Ambassador, the assurance of my high consideration.
People’s Commissar for Foreign Affairs of the U.S.S.R.

The Extraordinary and Plenipotentiary Ambassador of Poland, Mr. Grzybowski

The antics of FX intervention – the case of Turkey

I have often been puzzled by central banks’ dislike of currency flexibility. This is also the case for many central banks, which officially operating floating exchange rate regimes.

The latest example of this kind of antics is the Turkish central bank’s recent intervention to prop as the Turkish lira after it has depreciated significantly in connection with the recent political unrest. This is from

“On Monday, the Turkish central bank attempted to stop the currency’s slide by selling a record amount of foreign-exchange reserves in seven back-to-back auctions. The bank sold $2.25 billion dollars, or around 5 percent of its net reserves, to shore up its currency – the most it has ever spent to do so”

A negative demand shock in response to a supply shock

I have earlier described the political unrest in Turkey as a negative supply shock and it follows naturally from currency theory that a negative supply shock is negative for the currency and in that sense it shouldn’t be a surprise that the political unrest has caused the lira to weaken. One can always discuss the scale of the weakening, but it is hard to dispute that increased ‘regime uncertainty’ should cause the lira to weaken.

It follows from ‘monetary theory 101′ that central banks should not react to supply shocks – positive or negative. However, central banks are doing that again and again nonetheless and the motivation often is that central banks see market moves as “excessive” or “irrational” and therefore something they need to “correct”. This is probably also the motivation for the Turkish central bank. But does that make any sense economically? Not in my view.

We can illustrate the actions of the Turkish central bank in a simple AS/AD framework.

AS AD SRAS shock Turkey

The political unrest has increased ‘regime uncertainty’, which has shifted the short-run aggregate supply curve (SRAS) to the left. This push up inflation to P’ and output/real GDP drops to Y’.

In the case of a nominal GDP targeting central bank that would be it. However, in the case of Turkey the central bank (TCMB) has reacted by effectively tightening monetary conditions. After all FX intervention to prop up the currency is “reverse quantitative easing” – the TCMB has effectively cut the money base by its actions. This a negative demand shock.

In the graph this mean that the AD curve shifts  to the left from AD to AD’. This will push down inflation to P” and output to Y”.

In the example the combined impact of a supply shock and the demand shock is an increase in inflation. However, that is not necessarily given and dependent the shape of the SRAS curve and the size of the demand shock.

However, more importantly there is no doubt about the impact on real GDP growth – it will contract and the FX intervention will exacerbate the negative effects of the initial supply shock.

So why would the central bank intervene? Well, if we want to give the TCMB the benefit of the doubt the simple reason is that the TCMB has an inflation target. And since the negative supply shock increases inflation one could hence argue that the TCMB is “forced” by its target to tighten monetary policy. However, if that was the case why intervene in the FX market? Why not just use the normal policy instrument – the key policy interest rates?

My view is that this is a simple case of ‘fear-of-floating’ and the TCMB is certainly not the only central bank to suffer from this irrational fear. Recently the Polish central bank has also intervened to prop up the Polish zloty despite the Polish economy is heading for deflation in the coming months and growth is extremely subdued.

The cases of Turkey and Poland in my view illustrate that central banks are often not guided by economic logic, but rather by political considerations. Mostly central banks will refuse to acknowledge currency weakness is a result of for example bad economic policies and would rather blame “evil speculators” and “irrational” behaviour by investors and FX intervention is hence a way to signal to voters and others that the currency sell-off should not be blamed on bad policies, but on the “speculators”.

In that sense the central banks are the messengers for politicians. This is what Turkish Prime Minister Erdogan recently had to say about what he called the “interest rate lobby”:

“The lobby has exploited the sweat of my people for years. You will not from now on…

…Those who attempt to sink the bourse, you will collapse. Tayyip Erdogan is not the one with money on the bourse … If we catch your speculation, we will choke you. No matter who you are, we will choke you

…I am saying the same thing to one bank, three banks, all banks that make up this lobby. You have started this fight against us, you will pay the high price for it.

..You should put the high-interest-rate lobby in their place. We should teach them a lesson. The state has banks as well, you can use state banks.”

So it is the “speculators” and the banks, which are to blame. Effectively the actions of the TCMB shows that the central banks at least party agrees with this assessment.

Finally, when a central bank intervenes in the currency market in reaction to supply shocks it is telling investors that it effectively dislikes fully floating exchange rates and therefore it will effectively reduce the scope of currency adjustments to supply shocks. This effective increases in the negative growth impact of the supply shock. In that sense FX intervention is the same as saying “we prefer volatility in economic activity to FX volatility”. You can ask yourself whether this is good policy or not. I think my readers know what my view on this is.

Update: I was just reminded of a quote from H. L. Mencken“For every problem, there’s a simple solution. And it’s wrong.”

The economics of airport security – the case of Poland

I am writing this sitting in Warsaw’s Chopin airport. Over the last decade I have spend more time in Chopin than in any other airport in the world. The airport has changed a lot over the years and the development in the airport in many ways seem to have tracked the development in the rest of the Polish economy.

In many ways one can say that airports are reflections of the countries in which they are located. Airports tell stories of economic, social and cultural development.

Today I got a very pleasant surprise when I arrived at the airport. A surprise that fundamentally makes me quite a bit more optimistic about Poland’s long-run growth perspectives.

So what have changed at Chopin airport? Well, it is simple, but in my view quite important – airport security has been changed. Until recently and as long back I can remember (more than a decade) the staff taking care of the security check at Chopin airport has been uniformed militia style people in combat style outfits armed with guns.

These people have never seemed especially concerned about seeing their jobs as a service to clients at the airport. Rather they generally never smiled and in general were quite inefficient in getting people through the airport security check.

Today, however, I was not meet by armed military style people, but instead by polite and a lot more efficient staff dressed in normal cloth – and nice orange ties. They looked like the personal in Scandinavian airports. I guess they are personel of a private company rather than government employees (remember they actually smiled…).

Friendly, well-dressed and efficient. Gone were the scary looking, but lazy militia type people. That indeed was a nice surprise.

Over the years have given a lot of thought to exactly what we can learn about airport security and I for many years have had a theory that countries that have military style airport security and where the security staff generally see passages as ‘animals’ which potentially are a threat to security rather than clients that should be served also are countries where government regulation is excessive in other areas of economic life.

Hence, my theory is that if you meet an unfriendly bureaucrat at the security check in the airport then it is also very likely it will be hard to start a business in that country. Therefore, I tend to think of airport security as an indicator of the level of government regulation of the country’s economy. This is something that makes me terribly bearish on the US’ long-term growth perspectives every time I encounter a TSA official in an US airport – and makes me terribly depressed about the prospects for Ukraine and it gives me an understanding of why the Scandinavian countries ‘works’ well despite excessively large public sectors.

It was therefore a pleasure today to meet friendly and efficient people at the security check in Chopin airport. And if my theory has any value this is an indication that Poland has “matured” and the level of regulation is luckily getting lighter. That is good news. So now I am thinking of raising my long-run growth forecasts for Poland…

I would love to hear my readers’ experience with airport security around the world and whether you see the same correlation between the “friendliness” of airport security and the ease of doing business.

PS I have for some time been looking for data on the efficiency of airport security. If any of my readers have knowledge of such data please let me know.

PPS I am less positive on the near-term outlook for Poland. Polish monetary policy has been excessively tight since early 2012. As a consequence the Polish economy is now seeing a sharp slowdown in growth. See my later forecast on the Polish economy here.

Sweden, Poland and Australia should have a look at McCallum’s MC rule

Sweden, Poland and Australia all managed the shock from the outbreak of Great Recession quite well and all three countries recovered relatively fast from the initial shock. That meant that nominal GDP nearly was brought back to the pre-crisis trend in all three countries and as a result financial distress and debt problems were to a large extent avoided.

As I have earlier discussed on my post on Australian monetary policy there is basically three reasons for the success of monetary policy in the three countries (very broadly speaking!):

1)     Interest rates were initially high so the central banks of Sweden, Poland and Australia could cut rates without hitting the zero lower bound (Sweden, however, came very close).

2)     The demand for the countries’ currencies collapsed in response to the crisis, which effectively led to “automatic” monetary easing. In the case of Sweden the Riksbank even seemed to welcome the collapse of the krona.

3)     The central banks in the three countries chose to interpret their inflation targeting mandates in a “flexible” fashion and disregarded any short-term inflationary impact of weaker currencies.

However, recently the story for the three economies have become somewhat less rosy and there has been a visible slowdown in growth in Poland, Sweden and Australia. As a consequence all three central banks are back to cutting interest rates after increasing rates in 2009/10-11 – and paradoxically enough the slowdown in all three countries seems to have been exacerbated by the reluctance of the three central banks to re-start cutting interest rates.

This time around, however, the “rate cutting cycle” has been initiated from a lower “peak” than was the case in 2008 and as a consequence we are once heading for “new lows” on the key policy rates in all three countries. In fact in Australia we are now back to the lowest level of 2009 (3%) and in Sweden the key policy rate is down to 1.25%. So even though rates are higher than the lowest of 2009 (0.25%) in Sweden another major negative shock – for example another escalation of the euro crisis – would effectively push the Swedish key policy rate down to the “zero lower bound” – particularly if the demand for Swedish krona would increase in response to such a shock.

Market Monetarists – like traditional monetarists – of course long have argued that “interest rate targeting” is a terribly bad monetary instrument, but it nonetheless remains the preferred policy instrument of most central banks in the world. Scott Sumner has suggested that central banks instead should use NGDP futures in the conduct of monetary policy and I have in numerous blog posts suggested that central banks in small open economies instead of interest rates could use the currency rate as a policy instrument (not as a target!). See for example my recent post on Singapore’s monetary policy regime.

Bennett McCallum has greatly influenced my thinking on monetary policy and particularly my thinking on using the exchange rate as a policy instrument and I would certainly suggest that policy makers should take a look at especially McCallum’s research on the conduct of monetary policy when interest rates are close to the “zero lower bound”.

In McCallum’s 2005 paper “A Monetary Policy Rule for Automatic Prevention of a Liquidity Trap? he discusses a new policy rule that could be highly relevant for the central banks in Sweden, Poland and Australia – and for matter a number of other central banks that risk hitting the zero lower bound in the event of a new negative demand shock (and of course for those who have ALREADY hit the zero lower bound as for example the Czech central bank).

What McCallum suggests is basically that central banks should continue to use interest rates as the key policy instruments, but also that the central bank should announce that if interest rates needs to be lowered below zero then it will automatically switch to a Singaporean style regime, where the central bank will communicate monetary easing and tightening by announcing appreciating/depreciating paths for the country’s exchange rate.

McCallum terms this rule the MC rule. The reason McCallum uses this term is obviously the resemblance of his rule to a Monetary Conditions Index, where monetary conditions are expressed as an index of interest rates and the exchange rate. The thinking behind McCallum’s MC rule, however, is very different from a traditional Monetary Conditions index.

McCallum basically express MC in the following way:

(1) MC=(1-Θ)R+Θ(-Δs)

Where R is the central bank’s key policy rate and Δs is the change in the nominal exchange rate over a certain period. A positive (negative) value for Δs means a depreciation (an appreciation) of the country’s currency. Θ is a weight between 0 and 1.

Hence, the monetary policy instrument is expressed as a weighted average of the key policy rate and the change in the nominal exchange.

It is easy to see that if interest rates hits zero (R=0) then monetary policy will only be expressed as changes in the exchange rate MC=Θ(-Δs).

While McCallum formulate the MC as a linear combination of interest rates and the exchange rate we could also formulate it as a digital rule where the central bank switches between using interest rates and exchange rates dependent on the level of interest rates so that when interest rates are at “normal” levels (well above zero) monetary policy will be communicated in terms if interest rates changes, but when we get near zero the central bank will announce that it will switch to communicating in changes in the nominal exchange rate.

It should be noted that the purpose of the rule is not to improve “competitiveness”, but rather to expand the money base via buying foreign currency to achieve a certain nominal target such as an inflation target or an NGDP level target. Therefore we could also formulate the rule for example in terms of commodity prices (that would basically be Irving Fisher’s Compensated dollar standard) or for that matter stock prices (See my earlier post on how to use stock prices as a monetary policy instrument here). That is not really important. The point is that monetary policy is far from impotent. There might be a Zero Lower Bound, but there is no liquidity trap. In the monetary policy debate the two are mistakenly often believed to be the same thing. As McCallum expresses it:

It would be better, I suggest, to use the term “zero lower bound situation,” rather than “liquidity trap,” since the latter seems to imply a priori that there is no available mechanism for generating monetary policy stimulus”

Implementing a MC rule would be easy, but very effective

So central banks are far from “out of ammunition” when they hit the zero lower bound and as McCallum demonstrates the central bank can just switch to managing the exchange rates when that happens. In the “real world” the central banks could of course announce they will be using a MC style instrument to communicate monetary policy. However, this would mean that central banks would have to change their present operational framework and the experience over the past four years have clearly demonstrated that most central banks around the world have a very hard time changing bad habits even when the consequence of this conservatism is stagnation, deflationary pressures, debt crisis and financial distress.

I would therefore suggest a less radical idea, but nonetheless an idea that essentially would be the same as the MC rule. My suggestion would be that for example the Swedish Riksbank or the Polish central bank (NBP) should continue to communicate monetary policy in terms of changes in the interest rates, but also announce that if interest rates where to drop below for example 1% then the central bank would switch to communicating monetary policy changes in terms of projected changes in the exchange rate in the exact same fashion as the Monetary Authorities are doing it in Singapore.

You might object that in for example in Poland the key policy rate is still way above zero so why worry now? Yes, that is true, but the experience over the last four years shows that when you hit the zero lower bound and there is no pre-prepared operational framework in place then it is much harder to come up with away around the problem. Furthermore, by announcing such a rule the risk that it will have to “kick in” is in fact greatly reduced – as the exchange rate automatically would start to weaken as interest rates get closer to zero.

Imagine for example that the US had had such a rule in place in 2008. As the initial shock hit the Federal Reserve was able to cut rates but as fed funds rates came closer to zero the investors realized that there was an operational (!) limit to the amount of monetary easing the fed could do and the dollar then started to strengthen dramatically. However, had the fed had in place a rule that would have led to an “automatic” switch to a Singapore style policy as interest rates dropped close to zero then the markets would have realized that in advance and there wouldn’t had been any market fears that the Fed would not ease monetary policy further. As a consequence the massive strengthening of the dollar we saw would very likely have been avoided and there would probably never had been a Great Recession.

The problem was not that the fed was not willing to ease monetary policy, but that it operationally was unable to do so initially. Tragically Al Broaddus president of the Richmond Federal Reserve already back in 2003 (See Bob Hetzel’s “Great Recession – Market Failure or Policy Failure?” page 301) had suggested the Federal Reserve should pre-announce what policy instrument(s) should be used in the event that interest rates hit zero. The suggestion tragically was ignored and we now know the consequence of this blunder.

The Swedish Riksbank, the Polish central bank and the Australian Reserve Bank could all avoid repeating the fed’s blunder by already today announcing a MC style. That would lead to an “automatic prevention of the liquidity trap”.

PS it should be noted that this post is not meant as a discussion about what the central bank ultimately should target, but rather about what instruments to use to hit the given target. McCallum in his 2005 paper expresses his MC as a Taylor style rule, but one could obviously also think of a MC rule that is used to implement for example a price level target or even better an NGDP level rule and McCallum obviously is one of the founding father of NGDP targeting (I have earlier called McCallum the grandfather of Market Monetarism).

Dangerous bubble fears

Here is Swedish central bank governor Stefan Ingves in an op-ed piece in the Swedish newspaper Svenska Dagbladet last week:

“I also have to take responsibility for the long term consequences of today’s monetary policy…And there are risks associated with an all too low interest rate over a long period, which cannot be ignored.”

Said in another way if we keep interest rates too low we will get bubbles. So despite very clear signs that the Swedish economy is slowing Ingves would not like to ease monetary policy. Ingves in that sense is similar to many central bankers around the world. Many central bankers have concluded that the present crisis is a result of a bubble that bursted and the worst you could do is to ease monetary policy – even if the economic data is telling you that that is exactly what you should.

The sentiment that Ingves is expressing is similar to the view of the ECB and the fed in 2008/9: We just had a bubble and if we ease too aggressively we will get another one. Interestingly enough those central banks that did well in 2008/9 and eased monetary policy more aggressively and therefore avoided major crisis today seem to be most fearful about “bubbles”. Take the Polish central bank (NBP). The NBP in 2009 allowed the zloty to weaken significantly and cut interest rates sharply. That in my view saved the Polish economy from recession in 2009 – Poland was the only country in Europe with positive real GDP growth in 2009. However, today the story is different. NBP hiked interest rates earlier in the year and is now taking very long time in easing monetary policy despite very clear signs the Polish economy is slowing quite fast. In that sense you can say the NBP has failed this year because it did so well in 2009.

The People’s Bank of China in many ways is the same story – the PBoC eased monetary policy aggressively in 2009 and that pulled the Chinese economy out of the crisis very fast, but since 2010 the PBoC obviously has become fearful that it had created a bubble – which is probably did. To me Chinese monetary policy probably became excessively easy in early 2010 so it was right to scale back on monetary easing, but money supply growth has slowed very dramatically in the last two years and monetary policy now seem to have become excessively tight.

So the story is the same in Sweden, Poland and China. The countries that escaped the crisis did so by easing monetary conditions. As their exports collapsed domestic demand had to fill the gap and easier monetary policy made that possible. So it not surprising that these countries have seen property prices continuing to increase during the last four years and also have seen fairly strong growth in private consumption and investments. However, this now seem to be a major headache for central bankers in these countries.

I think these bubble fears are quite dangerous. It was this kind of fears that led the fed and the ECB to allow monetary conditions to become excessive tight in 2008/9. Riksbanken, NBP and the PBoC now risk making the same kind of mistake.

At the core of this problem is that central bankers are trying to concern themselves with relative prices. Monetary policy is very effective when it comes to determine the price level or nominal GDP, but it is also a very blunt instrument. Monetary policy cannot – and certainly should not – influence relative prices. Therefore, the idea that the central bank should target for example property prices in my view is quite a unhealthy suggestion.

Obviously I do not deny that overly easy monetary policy under certain circumstances can lead to the formation of bubbles, but it should not be the job of central bankers to prick bubbles.

The best way to avoid that monetary policy do not create bubbles is that the central bank has a proper monetary target such as NGDP level targeting. Contrary to inflation targeting where positive supply shocks can lead to what Austrians call relative inflation there is not such a risk with NGDP level targeting.

Let’s assume that the economy is hit by a positive supply shock – for example lower import prices. That would push down headline inflation. An inflation targeting central bank – like Riksbanken and NBP – in that situation would ease monetary policy and as a result you would get relative inflation – domestic prices would increase relative to import prices and that is where you get bubbles in the property markets. Under NGDP level targeting the central bank would not ease monetary policy in response to a positive supply shock and inflation would drop ease, but the NGDP level would on the other hand remain on track.

However, the response to a demand shock – for example a drop in money velocity – would be symmetric under NGDP level targeting and inflation target. Both under IT and NGDP targeting the central bank would ease monetary policy. However, this is not what central banks that are concerned about “bubbles” are doing. They are trying to target more than one target. The first page in the macroeconomic textbook, however, tells you that you cannot have more policy targets than policy instruments. Hence, if you target a certain asset price – like property prices – it would mean that you effectively has abandoned your original target – in the case of Riksbanken and NBP that is the inflation target. So when governor Ingves express concern about asset bubbles he effective has said that he for now is not operating an inflation targeting regime. I am sure his colleague deputy governor Lars E. O. Svensson is making that argument to him right now.

I don’t deny that bubbles exist and I am not claiming that there is no bubbles in the Swedish, Polish or Chinese economies (I don’t know the answer to that question). However, I am arguing that monetary policy is a very bad instrument to “fight” bubbles. Monetary policy should not add to the risk of bubbles, but “bubble fighting” should not be the task of the central bank. The central bank should ensure nominal stability and let the market determine relative prices in the economy. Obviously other policies – such as tax policy or fiscal policy should not create moral hazard problems through implicit or explicit guarantees to “bubble makers”.

Japan has been in a 15 year deflationary environment with falling asset prices and a primary reason for that is the Bank of Japan’s insane fear of creating bubbles. I doubt that the Riksbank, NBP or the PBoC will make the same kind of mistakes, but bubbles have clearly led all three central banks to become overly cautious and as a result the Swedish, the Polish and the Chinese economy are now cooling too much.

I should stress that I do not suggest some kind of “fine tuning” policy, but rather I suggest that central banks should focus on one single policy target – and I prefer NGDP level targeting – and leave other issues to other policy makers. If central banks are concerned about bubbles they should convince politicians to implement policies that reduce moral hazard rather than trying to micromanage relative prices and then of course focus on a proper and forward looking monetary policy target like NGDP level targeting.

PS Note that I did not mention the interest rate fallacy, but I am sure Milton Friedman would have told governor Ingves about it.

International monetary disorder – how policy mistakes turned the crisis into a global crisis

Most Market Monetarist bloggers have a fairly US centric perspective (and from time to time a euro zone focus). I have however from I started blogging promised to cover non-US monetary issues. It is also in the light of this that I have been giving attention to the conduct of monetary policy in open economies – both developed and emerging markets. In the discussion about the present crisis there has been extremely little focus on the international transmission of monetary shocks. As a consequences policy makers also seem to misread the crisis and why and how it spread globally. I hope to help broaden the discussion and give a Market Monetarist perspective on why the crisis spread globally and why some countries “miraculously” avoided the crisis or at least was much less hit than other countries.

The euro zone-US connection

– why the dollar’ status as reserve currency is important

In 2008 when crisis hit we saw a massive tightening of monetary conditions in the US. The monetary contraction was a result of a sharp rise in money (dollar!) demand and as the Federal Reserve failed to increase the money supply we saw a sharp drop in money-velocity and hence in nominal (and real) GDP. Hence, in the US the drop in NGDP was not primarily driven by a contraction in the money supply, but rather by a drop in velocity.

The European story is quite different. In Europe the money demand also increased sharply, but it was not primarily the demand for euros, which increased, but rather the demand for US dollars. In fact I would argue that the monetary contraction in the US to a large extent was a result of European demand for dollars. As a result the euro zone did not see the same kind of contraction in money (euro) velocity as the US. On the other hand the money supply contracted somewhat more in the euro zone than in the US. Hence, the NGDP contraction in the US was caused by a contraction in velocity, but in the euro zone the NGDP contraction was caused to drop by both a contraction in velocity and in the money supply. Reflecting a much less aggressive response by the ECB than by the Federal Reserve.

To some extent one can say that the US economy was extraordinarily hard hit because the US dollar is the global reserve currency. As a result global demand for dollar spiked in 2008, which caused the drop in velocity (and a sharp appreciation of the dollar in late 2008).

In fact I believe that two factors are at the centre of the international transmission of the crisis in 2008-9.

First, it is key to what extent a country’s currency is considered as a safe haven or not. The dollar as the ultimate reserve currency of the world was the ultimate safe haven currency (and still is) – as gold was during the Great Depression. Few other currencies have a similar status, but the Swiss franc and the Japanese yen have a status that to some extent resembles that of the dollar. These currencies also appreciated at the onset of the crisis.

Second, it is completely key how monetary policy responded to the change in money demand. The Fed failed to increase the money supply enough to the increase in the dollar demand (among other things because of the failure of the primary dealer system). On the other hand the Swiss central bank (SNB) was much more successful in responding to the sharp increase in demand for Swiss franc – lately by introducing a very effective floor for EUR/CHF at 1.20. This means that any increase in demand for Swiss franc will be met by an equally large increase in the Swiss money supply. Had the Fed implemented a similar policy and for example announced in September 2008 that it would not allow the dollar to strengthen until US NGDP had stopped contracting then the crisis would have been much smaller and would long have been over.

Why was the contraction so extreme in for example the PIIGS countries and Russia?

While the Fed failed to increase the money supply enough to counteract the increase in dollar demand it nonetheless acted through a number of measures. Most notably two (and a half) rounds of quantitative easing and the opening of dollar swap lines with other central banks in the world. Other central banks faced bigger challenges in terms of the possibility – or rather the willingness – to respond to the increase in dollar demand. This was especially the case for countries with fixed exchanges regimes – for example Denmark, Bulgaria and the Baltic States – and countries in currencies unions – most notably the so-called PIIGS countries.

I have earlier showed that when oil prices dropped in 2008 the Russian ruble started depreciated (the demand for ruble dropped). However, the Russian central bank would not accept the drop in the ruble and was therefore heavily intervening in the currency market to curb the ruble depreciation. The result was a 20% contraction in the Russian money supply in a few months during the autumn of 2008. As a consequence Russia saw the biggest real GDP contraction in 2009 among the G20 countries and rather unnecessary banking crisis! Hence, it was not a drop in velocity that caused the Russian crisis but the Russian central bank lack of willingness to allow the ruble to depreciate. The CBR suffers from a distinct degree of fear-of-floating and that is what triggered it’s unfortunate policy response.

The ultimate fear-of-floating is of course a pegged exchange rate regime. A good example is Latvia. When the crisis hit the Latvian economy was already in the process of a rather sharp slowdown as the bursting of the Latvian housing bubble was unfolding. However, in 2008 the demand for Latvian lat collapsed, but due to the country’s quasi-currency board the lat was not allowed to depreciate. As a result the Latvian money supply contracted sharply and send the economy into a near-Great Depression style collapse and real GDP dropped nearly 30%. Again it was primarily the contraction in the money supply rather and a velocity collapse that caused the crisis.

The story was – and still is – the same for the so-called PIIGS countries in the euro zone. Take for example the Greek central bank. It is not able to on it’s own to increase the money supply as it is part of the euro area. As the crisis hit (and later escalated strongly) banking distress escalated and this lead to a marked drop in the money multiplier and drop in bank deposits. This is what caused a very sharp drop in the Greek board money supply. This of course is at the core of the Greek crisis and this has massively worsened Greece’s debt woes.

Therefore, in my view there is a very close connection between the international spreading of the crisis and the currency regime in different countries. In general countries with floating exchange rates have managed the crisis much better than countries with countries with pegged or quasi-pegged exchange rates. Obviously other factors have also played a role, but at the key of the spreading of the crisis was the monetary policy and exchange rate regime in different countries.

Why did Sweden, Poland and Turkey manage the crisis so well?

While some countries like the Baltic States or the PIIGS have been extremely hard hit by the crisis others have come out of the crisis much better. For countries like Poland, Turkey and Sweden nominal GDP has returned more or less to the pre-crisis trend and banking distress has been much more limited than in other countries.

What do Poland, Turkey and Sweden have in common? Two things.

First of all, their currencies are not traditional reserve currencies. So when the crisis hit money demand actually dropped rather increased in these countries. For an unchanged supply of zloty, lira or krona a drop in demand for (local) money would actually be a passive or automatic easing of monetary condition. A drop in money demand would also lead these currencies to depreciate. That is exactly what we saw in late 2008 and early 2009. Contrary to what we saw in for example the Baltic States, Russia or in the PIIGS the money supply did not contract in Poland, Sweden and Turkey. It expanded!

And second all three countries operate floating exchange rate regimes and as a consequence the central banks in these countries could act relatively decisively in 2008-9 and they made it clear that they indeed would ease monetary policy to counter the crisis. Avoiding crisis was clearly much more important than maintaining some arbitrary level of their currencies. In the case of Sweden and Turkey growth rebound strongly after the initial shock and in the case of Poland we did not even have negative growth in 2009. All three central banks have since moved to tighten monetary policy – as growth has remained robust. The Swedish Riksbank is, however, now on the way back to monetary easing (and rightly so…)

I could also have mentioned the Canada, Australia and New Zealand as cases where the extent of the crisis was significantly reduced due to floating exchange rates regimes and a (more or less) proper policy response from the local central banks.

Fear-of-floating via inflation targeting

Some countries fall in the category between the PIIGS et al and Sweden-like countries. That is countries that suffer from an indirect form of fear-of-floating as a result of inflation targeting. The most obvious case is the ECB. Unlike for example the Swedish Riksbank or the Turkish central bank (TCMB) the ECB is a strict inflation targeter. The ECB does target headline inflation. So if inflation increases due to a negative supply shock the ECB will move to tighten monetary policy. It did so in 2008 and again in 2011. On both occasions with near-catastrophic results. As I have earlier demonstrated this kind of inflation targeting will ensure that the currency will tend to strengthen (or weaken less) when import prices increases. This will lead to an “automatic” fear-of-floating effect. It is obviously less damaging than a strict currency peg or Russian style intervention, but still can be harmful enough – as it clear has been in the case of the euro zone.

Conclusion: The (international) monetary disorder view explains the global crisis

I hope to have demonstrated above that the increase in dollar demand in 2008 not only hit the US economy but also lead to a monetary contraction in especially Europe. Not because of an increase demand for euro, lats or rubles, but because central banks tighten monetary policy either directly or indirectly to “manage” the weakening of their currencies. Or because they could not ease monetary policy as member of the euro zone. In the case of the ECB the strict inflation targeting regime let the ECB to fail to differentiate between supply and demand shocks which undoubtedly have made things a lot worse.

The international transmission was not caused by “market disorder”, but by monetary policy failure. In a world of freely floating exchange rates (or PEP – currencies pegged to export prices) and/or NGDP level targeting the crisis would never have become a global crisis and I certainly would have no reason to write about it four-five years after the whole thing started.

Obviously, the “local” problems would never have become any large problem had the Fed and the ECB got it right. However, the both the Fed and the ECB failed – and so did monetary policy in a number of other countries.

DISCLAIMER: I have discussed different countries in this post. I would however, stress that the different countries are used as examples. Other countries – both the good, the bad and the ugly – could also have been used. Just because I for example highlight Poland, Turkey and Sweden as good examples does not mean that these countries did everything right. Far from it. The Polish central bank had horrible communication in early 2009 and was overly preoccupied the weakening of the zloty. The Turkish central bank’s communication was horrific last year and the Sweden bank has recently been far too reluctant to move towards monetary easing. And I might even have something positive to say about the ECB, but let me come back on that one when I figure out what that is (it could take a while…) Furthermore, remember I often quote Milton Friedman for saying you never should underestimate the importance of luck of nations. The same goes for central banks.

PS You are probably wondering, “Why did Lars not mention Asia?” Well, that is easy – the Asian economies in general did not have a major funding problem in US dollar (remember the Asian countries’ general large FX reserve) so dollar demand did not increase out of Asia and as a consequence Asia did not have the same problems as Europe. Long story, but just show that Asia was not key in the global transmission of the crisis and the same goes for Latin America.
