Differences in central banker pay illustrates why the euro is not an “optimal currency area”

Bloomberg has a great story on differences in the pay of different central bank governors within the euro area.

This graph is from the Bloomberg story:

cb pay

As the graph illustrates there is a massive difference between how much the different euro zone central bank governors are paid. These differences probably very well reflect the general differences in income levels within the euro area.

Normally we would say that a core condition for being a “Optimal Currency Area” is that the income (productivity) level of different countries/regions within the currency area should be on a fairly similar level. The pay differences of euro zone central bankers illustrates quite well that this core condition is not fulfilled within the euro area.

PS  This is from the Bloomberg story: “The economic turmoil has also crimped earnings at the Greek central bank. Governor Yannis Stournaras gets 7,342 euros a month after taxes following two rounds of voluntary cuts by his predecessor, by 20 percent and 30 percent.”

Merry Christmas

Dear friends and readers,

Christmas is family time – also in the Christensen family so this will be a short post.

I just want to thank all my loyal readers and followers for following and commenting on my blog (and following me on Twitter and Facebook).

It gives me lots of joy writing my blog and it is getting me in contact with interesting people from all over the world. I am grateful for that. For those of you who are celebrating Christmas these days I wish you a Merry Christmas.

See you all soon!

PS I have the same wish-list as George Selgin (just replace George’s “Bitdollar” protocol with a NGDP futures market and add a wish number 11 that I want the ECB to do this)

Importing monetary tightening – the case of Belarus

Everybody has been following events in the Russian markets this week, but fewer have kept an eye on Russia’s smaller neighbour Belarus, but the small country is seeing some serious contagion from Russia.

With the Belarusian rouble effectively pegged to the US dollar and the Russian rouble in a free fall speculation has been mounting in Belarus that the Belarusian rouble (BYR) could be devalued.

And then on Friday Belarusian central bank reacted to these pressures and hiked its key policy rate to 50%! Furthermore, the authorities tightened currency controls by imposing a 30 per cent tax on buying foreign currency.

Nothing is of course forcing the Belarusian authorities to do this other than the desire to keep the BYR pegged to the dollar. That commitment now means that we will get a very significant tightening of monetary conditions in Belarus and as nearly always when such a tightenning happens you will get a sharp drop in economic activity. Once again it seems like the Belarusian authorities are importing a crisis from Russia.

I am not saying that I am advocating a Belarusian devaluation, but it is also clear that given the huge dependence on Russia it is hard for Belarus to maintain a peg to the US dollar when the Russian rouble is in a free fall.

It looks like 2015 will be an “interesting” year for Belarus – we will have presidential elections in November 2015.

Commodity prices, currencies and monetary policy

It has been a busy year for me – it has especially been the Russian-Ukrainian crisis, which has kept me busy. However, I thought that this week would be fairly calm – I didn’t have any traveling planned, not a lot a meetings scheduled and I had not expected to be too busy.

However, things turned out very differently thanks to the spectacular collapse of the Russian rouble and a massive rate hike from the Russian central bank. After 15 years in the financial markets this is absolutely up there among the wildest things I have ever experienced.

So frankly speaking I am a bit tired and not really up to the task of writing a major blog post. However, I have a lot on my mind nonetheless so I want share a bit of that anyway.

First, in relationship to what have played out in the Russian markets recently I must say that I actually have been impressed with the Russian central bank. Yes, Monday’s 650bp rate hike in my clearly is a major policy mistake and the decision has brought more uncertainty and more financial distress rather than stability and the rate hike will just send the already badly damaged Russian economy into a even deeper recession.

But one have to see the actions of the Russian central bank in the light of political pressures the central bank is under and that is the reason I am impressed. Russian monetary policy is far from great, but other Emerging Markets central banks would probably have made significantly worse decisions in a similar political and financial environment.

Second, while Market Monetarists advocate NGDP level targeting we have been less outspoken on our support for (N)GDP-linked bonds (in fact I am not sure the other MM bloggers like NGDP linked bonds as much as I do). However, I think the logic of market monetarism also implies that we should be advocating that governments should issue bonds linked to nominal GDP.

This would not only be a useful tools for monitoring market expectations for NGDP growth, but equally it would be helpful in “synchronizing” fiscal policy with monetary policy in the sense that fiscal policy would be automatically eased then the NGDP target is undershot and tightened when the target is overshot. This would also be helpful for countries where monetary policy is in different ways restricted for example by a fixed exchange rate regime.

Third, the Russia crisis “story” and the topic of NGDP-linked bonds can be combined to a discussion of whether the Russian government should issue government bonds linked to oil prices – so when oil prices decline then debt servicing costs also decline.

Just imagine what that would have done to reduce Russian default worries in the present situation. And this of course is linked to my favourite monetary framework for commodity exporters – the Export Price Norm. Hence, had all Russian government debt been linked to oil prices and had the rouble been pegged to a basket of US dollar (80%) and oil prices (20%) then I believe there would have been a much less spectacular crisis in Russia right now.

I hope to return to all these topics in the coming weeks, but until then I want to draw my readers’ attention to a recent blog post by my friend “Hishamh” over at Economics Malaysia on the topic of Commodities and Currencies. Here is Hishamh:

There’s quite a bit of gloom in the air these last few weeks. The plunge in oil and other commodity prices, capital pulling out of emerging markets, and currency turmoil, have people getting very worried about growth prospects next year. There doesn’t appear to be a bottom yet on oil prices, and it’s anybody’s guess where all this will end up.

In Malaysia’s case, oil price depreciation and Ringgit depreciation seems like one piling on the other – the latter is making things worse (Malaysians feel relatively poorer), on top of the drop in oil and gas revenues. But conflating the two like this is wrong. The depreciation of the currency is in fact a required and necessary result of the drop in oil prices.

If the Ringgit had stayed where it had been (about MYR3.20-3.30 to the USD), the full drop in oil prices would have been transmitted directly and with full force into the domestic economy. The approximate 8% depreciation of the Ringgit over the past few months partially mitigates that income shock. Since sales of oil (and gas) are denominated in USD terms on the international markets, a cheaper Ringgit partially cushions the revenue drop in local currency terms.

Consider that oil & gas make up about 20% of Malaysian exports; commodities as a whole about a third. That means that the drop in oil prices and the depreciation of the Ringgit have been nearly symmetrical. If anything, the Ringgit hasn’t dropped far enough – my estimate is that it should be at least 3%-5% weaker.

…That suggests the last few months currency action has largely been a USD movement rather than weakness in the MYR.

There’s also the flip side that the lower Ringgit should in theory provide a boost to non-commodity exports. In this case though, I’m a bit leery of depending on this as global demand growth outside the US and UK is pretty weak, and because again this is largely a case of Dollar strength more than Ringgit weakness.

…Some have been interpreting …central bank intervention to support the Ringgit value…My view is a little more nuanced – the drop in reserves is just too small to make that conclusion.

Contrasted with the pegged FX regime of the early ‘00s, reserve movements over the past four years are just too minor to affect the FX market. Rather, what I think is going on here is that BNM is simply trying to ensure that there’s enough USD (and other currency) liquidity in the interbank market to ensure, in their words, “orderly” market conditions.

…The bottom line is that BNM is not and will not be “defending” any level of the Ringgit. And if they’re not willing to spend reserves on it, you can forget the interest rate defense (which doesn’t work anyway).

Said in another way – the Malaysian central bank (BNM) has moved closer to my ideal of an Export Price Norm and that is benefiting the Malaysian economy. This is in fact what I suggested back in 2012 that the BNM should do.

Turning the Russian petro-monetary transmission mechanism upside-down

Big news out of Moscow today – not about the renewed escalation of military fighting in Eastern Ukraine, but rather about Russian monetary policy. Hence, today the Russian central bank (CBR) under the leadership of  Elvira Nabiullina effectively let the ruble float freely.

The CBR has increasing allowed the ruble to float more and more freely since 2008-9 within a bigger and bigger trading range. The Ukrainian crisis, negative Emerging Markets sentiments and falling oil prices have put the ruble under significant weakening pressures most of the year and even though the CBR generally has allowed for a significant weakening of the Russian currency it has also tried to slow the ruble’s slide by hiking interest rates and by intervening in the FX market. However, it has increasingly become clear that cost of the “defense” of the ruble was not worth the fight. So today the CBR finally announced that it would effectively float the ruble.

It should be no surprise to anybody who is reading my blog that I generally think that freely floating exchange rates is preferable to fixed exchange rate regimes and I therefore certainly also welcome CBR’s decision to finally float the ruble and I think CBR governor Elvira Nabiullina deserves a lot of praise for having push this decision through (whether or not her hand was forced by market pressures or not). Anybody familiar with Russian economic-policy decision making will know that this decision has not been a straightforward decision to make.

Elvira has turned the petro-monetary transmission mechanism upside-down

The purpose of this blog post is not necessarily to specifically discuss the change in the monetary policy set-up, but rather to use these changes to discuss how such changes impact the monetary transmission mechanism and how it changes the causality between money, markets and the economy in general.

Lets first start out with how the transmission mechanism looks like in a commodity exporting economy like Russia with a fixed (or quasi fixed) exchange rate like in Russia prior to 2008-9.

When the Russian ruble was fixed against the US dollar changes in the oil price was completely central to the monetary transmission – and that is why I have earlier called it the petro-monetary transmission mechanism. I have earlier explained how this works:

If we are in a pegged exchange rate regime and the price of oil increases by lets say 10% then the ruble will tend to strengthen as currency inflows increase. However, with a fully pegged exchange rate the CBR will intervene to keep the ruble pegged. In other words the central bank will sell ruble and buy foreign currency and thereby increase the currency reserve and the money supply (to be totally correct the money base). Remembering that MV=PY so an increase in the money supply (M) will increase nominal GDP (PY) and this likely will also increase real GDP at least in the short run as prices and wages are sticky.

So in a pegged exchange rate set-up causality runs from higher oil prices to higher money supply growth and then on to nominal GDP and real GDP and then likely also higher inflation. Furthermore, if the economic agents are forward-looking they will realize this and as they know higher oil prices will mean higher inflation they will reduce money demand pushing up money velocity (V) which in itself will push up NGDP and RGDP (and prices).

This effectively means that in such a set-up the CBR will have given up monetary sovereignty and instead will “import” monetary policy via the oil price and the exchange rate. In reality this also means that the global monetary superpower (the Fed and PBoC) – which to a large extent determines the global demand for oil indirectly will determine Russian monetary conditions.

Lets take the case of the People’s Bank of China (PBoC). If the PBoC ease monetary policy – increase monetary supply growth – then it will increase Chinese demand for oil and push up oil prices. Higher oil prices will push up currency inflows into Russia and will cause appreciation pressure on the ruble. If the ruble is pegged then the CBR will have to intervene to keep the ruble from strengthening. Currency intervention of course is the same as sell ruble and buying foreign currency, which equals an increase in the Russian money base/supply. This will push up Russian nominal GDP growth.

Hence, causality runs from the monetary policy of the monetary superpowers – Fed and the PBoC – to Russian monetary policy as long as the CBR pegs or even quasi-peg the ruble. However, the story changes completely when the ruble is floated.

I have also discussed this before:

If we assume that the CBR introduce an inflation target and let the ruble float completely freely and convinces the markets that it don’t care about the level of the ruble then the causality in or model of the Russian economy changes completely.

Now imagine that oil prices rise by 10%. The ruble will tend to strengthen and as the CBR is not intervening in the FX market the ruble will in fact be allow to strengthen. What will that mean for nominal GDP? Nothing – the CBR is targeting inflation so if high oil prices is pushing up aggregate demand in the economy the central bank will counteract that by reducing the money supply so to keep aggregate demand “on track” and thereby ensuring that the central bank hits its inflation target. This is really a version of the Sumner Critique. While the Sumner Critique says that increased government spending will not increase aggregate demand under inflation targeting we are here dealing with a situation, where increased Russian net exports will not increase aggregate demand as the central bank will counteract it by tightening monetary policy. The export multiplier is zero under a floating exchange rate regime with inflation targeting.

Of course if the market participants realize this then the ruble should strengthen even more. Therefore, with a truly freely floating ruble the correlation between the exchange rate and the oil price will be very high. However, the correlation between the oil price and nominal GDP will be very low and nominal GDP will be fully determined by the central bank’s target. This is pretty much similar to Australian monetary policy. In Australia – another commodity exporter – the central bank allows the Aussie dollar to strengthen when commodity prices increases. In fact in Australia there is basically a one-to-one relationship between commodity prices and the Aussie dollar. A 1% increase in commodity prices more or less leads to a 1% strengthening of Aussie dollar – as if the currency was in fact pegged to the commodity price (what Jeff Frankel calls PEP).

Therefore with a truly floating exchange rate there would be little correlation between oil prices and nominal GDP and inflation, but a very strong correlation between oil prices and the currency. This of course is completely the opposite of the pegged exchange rate case, where there is a strong correlation between oil prices and therefore the money supply and nominal GDP.

If today’s announced change in monetary policy set-up in Russia is taken to be credible (it is not necessary) then it would mean the completion of the transformation of the monetary transmission which essentially was started in 2008 – moving from a pegged exchange/manage float regime to a floating exchange rate.

This will also means that the CBR governor Elvira Nabiullina will have ensured full monetary sovereignty – so it will be her rather than the Federal Reserve and the People’s Bank of China, who determines monetary conditions in Russia.

Whether this will be good or bad of course fully dependent on whether Yellen or Nabiullina will conduct the best monetary policy for Russia.

One can of course be highly skeptical about the Russian central bank’s ability to conduct monetary policy in a way to ensure nominal stability – there is certainly not good track record, but given the volatility in oil prices it is in my view also hard believe that a fully pegged exchange rate would bring more nominal stability to the Russian economy than a floating exchange rate combined with a proper nominal target – either an inflation target or better a NGDP level target.

Today Elvira Nabiullina has (hopefully) finalized the gradual transformation from a pegged exchange to a floating exchange rate. It is good news for the Russian economy. It will not save the Russia from a lot of other economic headaches (and there are many!), but it will at least reduce the risk of monetary policy failure.

PS I still believe that the Russian economy is already in recession and will likely fall even deeper into recession in the coming quarters.

 

 

Time for the Fed to introduce a forward-looking McCallum rule

Earlier this week Boston Fed chief Eric Rosengreen in an interview on CNBC said that the Federal Reserve could introduce a forth round of quantitative easing – QE4 – since the beginning of the crisis in 2008 if the outlook for the US economy worsens.

I have quite mixed emotions about Rosengreen’s comments. I would of course welcome an increase in money base growth – what the Fed and others like to call quantitative easing – if it is necessary to ensure nominal stability in the US economy.

However, the way Rosengreen and the Fed in general is framing the use of quantitative easing in my view is highly problematic.

First of all when the fed is talking about quantitative easing it is speaking of it as something “unconventional”. However, there is nothing unconventional about using money base control to conduct monetary policy. What is unconventional is actually to use the language of interest rate targeting as the primary monetary policy “instrument”.

Second, the Fed continues to conduct monetary policy in a quasi-discretionary fashion – acting as a fire fighter putting out financial and economic fires it helped start itself.

The solution: Use the money base as an instrument to hit a 4% NGDP level target

I have praised the Fed for having moved closer to a rule based monetary policy in recent years, but the recent escalating distress in the US financial markets and particularly the marked drop in US inflation expectations show that the present monetary policy framework is far from optimal. I realize that the root of the recent distress likely is European and Chinese rather than American, but the fact that US inflation expectations also have dropped shows that the present monetary policy framework in the US is not functioning well-enough.

I, however, think that the Fed could improve the policy framework dramatically with a few adjustments to its present policy.

First of all the Fed needs to completely stop thinking about and communicating about its monetary stance in terms of setting an interest rate target. Instead the Fed should only communicate in terms of money base control.

The most straightforward way to do that is that at each FOMC meeting a monthly growth rate for the money base is announced. The announced monthly growth rate can be increased or decreased at every FOMC-meeting if needed to hit the Fed’s ultimate policy target.

Using “the” interest rate as a policy “instrument” is not necessarily a major problem when the “natural interest rate” for example is 4 or 5%, but if the natural interest rate is for example 1 or 2% and there is major slack in the economy and quasi-deflationary expectations then you again and again will run into a problem that the Fed hits the Zero Lower Bound everything even a small shock hits the economy. That creates an unnecessary degree of uncertainly about the outlook for monetary policy and a natural deflationary bias to monetary policy.

I frankly speaking have a hard time understanding why central bankers are so obsessed about communicating about monetary policy in terms of interest rate targeting rather than money base control, but I can only think it is because their favourite Keynesian models – both ‘old’ and ‘new’ – are “moneyless”.

I have earlier argued that the Fed since the summer of 2009 effectively has target 4% nominal GDP growth (level targeting). One can obviously argue that that has been too tight a monetary policy stance, but we have now seen considerable real adjustments in the US economy so even if the US economy likely could benefit from higher NGDP growth for a couple of year I would pragmatically suggest that the time has come to let bygones-be-bygones and make a 4% NGDP level target an official Fed target.

Alternatively the Fed could once every year announce its NGDP target for the coming five years based on an estimate for potential real GDP growth and the Fed’s 2% inflation target. So if the Fed thinks potential real GDP growth in the US in the coming five years is 2% then it would target 4% NGDP growth. If it thinks potential RGDP growth is 1.5% then it would target 3.5% growth.

However, it is important that the Fed targets a path level rather than the growth rate. Therefore, if the Fed undershoots the targeted level one year it would have to bring the NGDP level back to the targeted level as fast as possible.

Finally it is important to realize that the Fed should not be targeting the present level of NGDP, but rather the future level of NGDP. Therefore, when the FOMC sets the monthly growth rate of the money base it needs to know whether NGDP is ‘on track’ or not. Therefore a forecast for future NGDP is needed.

The way I – pragmatically – would suggest the FOMC handled this is that the FOMC should publish three forecasts based on three different methods for NGDP two years ahead.

The first forecast should be a forecast prepared by the Fed’s own economists.

The second forecast should be a survey of professional forecasts.

And finally the third forecast should be a ‘market forecast’. Scott Sumner has of course suggested creating a NGDP future, which the Fed could target or use as a forecasting tool. This I believe would be the proper ‘market forecast’. However, I also believe that a ‘synthetic’ NGDP future can relatively easily be created with a bit of econometric work and the input from market inflation expectations, the US stock market, a dollar index and commodity prices. In fact it is odd no Fed district has not already undertaken this task.

An idealised policy process

To sum up how could the Fed change the policy process to dramatically improve nominal stability and reduce monetary policy discretion?

It would be a two-step procedure at each FOMC meeting.

First, the FOMC would look at the three different forecasts for the NGDP level two-years ahead. These forecasts would then be compared to the targeted level of NGDP in two year.

The FOMC statement after the policy decision the three forecast should be presented and it should be made clear whether they are above or below the NGDP target level. This would greatly increase policy-making discipline. The FOMC members would be more or less forced to follow the “policy recommendation” implied by the forecasts for the NGDP level.

Second, the FOMC would decide on the monthly money base growth rate and it is clear that it follows logically that if the NGDP forecasts are below (above) the NGDP level target then the money base growth rate would have to be increased (decreased).

It think the advantages of this policy process would be enormous compared to the present quasi-discretionary and eclectic process and it would greatly move the Fed towards a truly rule-based monetary policy.

Furthermore, the process would be easily understood by the markets and by commentators alike and it would in no way be in conflict with the Fed’s official dual mandate as I strongly believe that such a set-up would both ensure price stability – defined as 2% inflation over the cycle – and “maximum employment”.

And finally back to the headline – “Time for the Fed to introduce a forward McCallum rule”. What I essentially have suggested above is that the Fed should introduce a forward-looking version of the McCallum rule. Bennett McCallum obviously originally formulated his rule in backward-looking terms (and in growth terms rather than in level terms), but I am sure that Bennett will forgive me for trying to formulate his rule in forward-looking terms.

PS if the ECB followed the exactly same rule as I have suggested above then the euro crisis would come to an end more or less immediately.

 

 

Soon everybody will be scared about ‘currency war’ again – we should be celebrating

With the dollar continuing to strengthen and now the Japanese yen starting to take off as well central bankers in the US and Japan are likely increasingly becoming worried about the deflationary tendencies of stronger currencies and recent comments from both countries’ central banks indicate that they will not allow their currencies to strengthen dramatically if it where to become deflationary.

This has in recent days caused some to begin to talk about the “risk” of a new global “currency war” where central banks around the world compete to weaken their currencies. Most commentators seem to think this would be horrible, but I would instead argue – as I have often done in recent years – that a global race to ease monetary policy is exactly what we need in a deflationary world.

If we lived in the high-inflation days of the 1970s we should be very worried, but we live in deflationary times so global monetary easing should be welcome and unlike most commentators I believe a global currency war would be a positive sum game.

Over the last couple of years I have written a number of posts on the topic of currency war. The main conclusions are the following:

  1. Currency war is a GREAT THING and is VERY POSITIVE – if indeed we think of it as a global competition to print money. This is what we need in a deflationary world.
  2. As long as we are seeing commodity prices decline and inflation expectations we can’t really say that the currency war is on yet.
  3. Currency war is NOT a zero sum game. It is a positive sum game in a deflationary world.
  4. Don’t think of monetary easing/currency depreciation to primarily work through a “competitiveness channel”, but rather through a boost to domestic demand. Therefore, we are likely to actually see the trade balance WORSEN for countries, which undertakes aggressive monetary easing. The US in 1933 is a good example. So is Argentina in 2001-2 and Japan recently. Sweden versus Denmark since 2008.

I don’t have much time to write more on the topic this morning, but I am sure I will return to the topic soon again. Until then have a look at my previous posts on the topic (and related topics):

The luck of the ‘Scandies’

The Fed’s un-announced 4% NGDP target was introduced already in July 2009

Scott Sumner started his now famous blog TheMoneyIllusion in February 2009 it was among other things “to show that we have fundamentally misdiagnosed the nature of the recession, attributing to the banking crisis what is actually a failure of monetary policy”.

Said in another way the Federal Reserve was to blame for the Great Recession and there was only one way out and that was monetary easing within a regime of nominal GDP level targeting (NGDP targeting).

NGDP targeting is of course today synonymous Scott Sumner. He more or less single-handedly “re-invented” NGDP targeting and created an enormous interest in the topic among academics, bloggers, financial sector economists and even policy makers.

The general perception is that NGDP targeting and Market Monetarism got the real break-through in 2013 when the Federal Reserve introduced the so-called Evans rule in September 2012 (See for example Matt Yglesias’ tribute to Scott from September 2012).

This has also until a few days ago been my take on the story of the success of Scott’s (and other’s) advocacy of NGDP targeting. However, I have now come to realize that the story might be slightly different and that the Fed effectively has been “market monetarist” (in a very broad sense) since July 2009.

The Fed might not have followed the MM game plan, but the outcome has effectively been NGDP targeting

Originally Scott basically argued that the Fed needed to bring the level nominal GDP back to the pre-crisis 5% trend path in NGDP that we had known during the so-called Great Moderation from the mid-1980s and until 2007-8.

We all know that this never happened and as time has gone by the original arguments for returning to the “old” NGDP trend-level seem much less convincing as there has been considerable supply side adjustments in the US economy.

Therefore, as time has gone by it becomes less important what is the “starting point” for doing NGDP targeting. Therefore, if we forgive the Fed for not bringing NGDP back to the pre-crisis trend-level and instead focus on the Fed’s ability to keep NGDP on “a straight line” then what would we say about the Fed’s performance in recent years?

Take a look at graph below – I have used (Nominal) Private Consumption Expenditure (PCE) as a monthly proxy for NGDP.

PCE gap

If we use July 2009 – the month the 2008-9 recession officially ended according to NBER – as our starting point (rather than the pre-crisis trend) then it becomes clear that in past five years PCE (and NGDP) has closely tracked a 4% path. In fact at no month over the past five years have PCE diverged more than 1% from the 4% path. In that sense the degree of nominal stability in the US economy has been remarkable and one could easily argue that we have had higher nominal stability in this period than during the so-called Great Moderation.

In fact I am pretty sure that if somebody had told Scott in July 2009 that from now on the Fed will follow a 4% NGDP target starting at the then level of NGDP then Scott would have applauded it. He might have said that he would have preferred a 5% trend rather than a 4% trend, but overall I think Scott would have been very happy to see a 4% NGDP target as official Fed policy.

The paradox is that Scott has not sounded very happy about the Fed’s performance for most of this period and neither have I and other Market Monetarists. The reason for this is that while the actual outcome has looked like NGDP targeting the Fed’s implementation of monetary policy has certainly not followed the Market Monetarist game plan.

Hence, the Market Monetarist message has all along been that the Fed should clearly announce its target (a NGDP level target), do aggressive quantitative easing to bring NGDP growth “back on track”, stop focusing on interest rates as a policy instrument and target expected NGDP rather than present macroeconomic variables. Actual US monetary policy has gradually moved closer to this ideal on a number of these points – particularly with the so-called Evan rule introduced in September 2012, but we are still very far away from having a Market Monetarist Fed when it comes to policy implementation.

However, in the past five years the implementation of Fed policy has been one of trial-and-error – just think of QE1, QE2 and QE3, two times “Operation Twist” and all kinds of credit policies and a continued obsession with using interest rates rates as the primary policy “instrument”.

I believe we Market Monetarists rightly have been critical about the Fed’s muddling through and lack of commitment to transparent rules. However, I also think that we today have to acknowledge that this process of trail-and-error actually has served an important purpose and that is to have sent a very clear signal to the financial markets (and others for that matter) that the Fed is committed to re-establishing some kind of nominal stability and avoiding a deflationary depression. This of course is contrary to the much less clear commitment of the ECB.

The markets have understood it all along (and much better than the Fed)

Market Monetarists like to say that the markets are better at forecasting and the collective wisdom of the markets is bigger than that of individual market participants or policy makers and something could actually indicate that the markets from an early point understood that the Fed de facto would be keeping NGDP on a straight line.

An example is the US stock market bottomed out a few months before we started to establish the new 4% trend in US NGDP and the US stock markets have essentially been on an upward trend ever since, which is fully justified if you believe the Fed will keep this de facto NGDP target in place. Then we should basically be expecting US stock prices to increase more or less in line with NGDP (disregarding changes to interest rates).

Another and even more powerful example in my view is what the currency markets have been telling us. I  (and other Market Monetarists) have long argued that market expectations play a key role in the in the implementation of monetary policy and in the monetary policy transmission mechanism.

In a situation where the central bank’s NGDP level target is credible rational investors will be able to forecast changes in the monetary policy stance based on the actual level of NGDP relative to the targeted level of NGDP. Hence, if actual NGDP is above the targeted level then it is rational to expect that the central bank will tighten the monetary policy stance to bring NGDP back on track with the target. This obviously has implications for the financial markets.

If the Fed is for example targeting a 4% NGDP path and the actual NGDP level is above this target then investors should rationally expect the dollar to strengthen until NGDP is back at the targeted level.

And guess what this is exactly how the dollar has traded since July 2009. Just take a look at the graph below.

NGDP gap dollar index 2

We are looking at the period where I argue that the Fed effectively has targeted a 4% NGDP path. Again I use PCE as a monthly proxy for NGDP and again the gap is the gap between the actual and the “targeted” NGDP (PCE) level. Look at the extremely close correlation with the dollar – here measured as a broad nominal dollar-index. Note the dollar-index is on an inverse axis.

The graph is very clear. When the NGDP gap has been negative/low (below target) as in the summer of 2010 then the dollar has weakened (as it was the case from from the summer of 2010under spring/summer of 2011. And similarly when the NGDP gap has been positive (NGDP above target) then the dollar has tended to strengthen as we essentially has seen since the second half of 2011 and until today.

I am not arguing that the dollar-level is determining the NGDP gap, but I rather argue that the dollar index has been a pretty good indicator for the future changes in monetary policy stance and therefore in NGDP.

Furthermore, I would argue that the FX markets essentially has figured out that the Fed de facto is targeting a 4% NGDP path and that currency investors have acted accordingly.

It is time for the Fed to fully recognize the 4% NGDP level target

Just because there has a very clear correlation between the dollar and the NGDP gap in the past five years it is not given that that correlation will remain in the future. A key reason for this is – and this is a key weakness in present Fed policy – that the Fed has not fully recognize that it is de facto targeting a 4%. Therefore, there is nothing that stops the Fed from diverging from the NGDP rule in the future.

Recognizing a 4% NGDP level target from the present level of NGDP in my view should be rather uncontroversial as this de facto has been the policy the Fed has been following over the past five years anyway. Furthermore, it could easily be argued as compatible  with the Fed’s (quasi) official 2% inflation target (assuming potential real GDP growth is around 2%).

In my previous post I argued that the ECB should introduce a 4% NGDP target. The Fed already done that. Now it is just up to Fed Chair Janet Yellen to announce it officially. Janet what are you waiting for?

Is Karnit Flug jeopardizing Stan Fischer’s “straight line policy”? Not yet, but…

It is no secret that I think that Stanley Fischer did a good job as governor of the Bank of Israel from 2005 to 2013. He basically saved Israel from the Great Recession by essentially keeping Israeli nominal GDP “on a straight line”. During his time in office the Israeli NGDP level diverged no more than 1-1.5% from what we could call the Fischer-trend.

However, Fischer is no longer at the BoI. Instead former deputy governor Karnit Flug has taken over – effectively from July 2013 and officially from November 2013. The question then is has Mrs. Flug been able to maintain Fischer’s “straight line policy” in place? The graph below gives us the answer.

Karnit Flug NGDP

The picture is pretty clear – essentially coinciding with Flug taking over as BoI governor the slowdown in NGDP growth (already started in 2012) has accelerated and we have now dropped somewhat below the Fischer-trend. It would be foolish to say that this in any way is catastrophic, but the change is nonetheless visible and should give reason for serious concern if it is allowed to continue to “drift off”.

Are inflation expectations becoming un-anchored? 

I have earlier warned that there is a risk that we are seeing inflation expectations becoming un-anchored in for example the euro zone because policy makers are preoccupied with everything else than focusing on their nominal target (for example an inflation target).

On the other hand I have also praised the Bank of Israel for always communicating in terms of (market) inflation expectations relative to the BoI’s 1-3% inflation target (range). However, one could argue that the Bank of Israel is beginning to look more like the Swedish Riksbank (which is preoccupied with household debt and  property prices) or the ECB (which is preoccupied by “everything else”).

A look at inflation expectations can tell us whether these fears are justified or not.

Inflation expectations Israel

The graph shows five different measures of inflation expectations. The first four are inflation expectations based on financial market pricing (BoI’s calculations) and the last one is based on a survey of professional forecasters.

Most of the measures show that there has been a pretty consistent downtrend in most of the measures of inflation expectations for little more than a year. However, it is also notable that we are still within the BoI’s 1-3% inflation target range and 5-year and 10-year inflation expectations are still close to 2% and as remained fairly stable.

Therefore, it is too early to say that inflation expectations have become un-anchored, but it should also be noted that we might be risking a sneaking un-anchoring of inflation expectations if policy actions is not taken to avoid it.

Bringing us back on the “straight line”

The recent rate cuts from the Bank of Israel shows that the BoI is not completely ignorant to these risks and I believe that particularly the latest rate cut to 0.25% on August 25 is helping in curbing deflationary pressures. However, more could likely be done to insure against the deflationary risks.

So what should Karnit Flug and her colleagues at the Bank of Israel do to bring us back to the Fischer-trend and to avoid an un-anchoring inflation expectations?

I have three suggestions:

1) Avoid repeating the mistakes of the Riksbank. The Swedish Riksbank has consistenly for some time now undershoot its official inflation target and in my view this has very much been the result of a preoccupation with household debts and property prices. Historical the Bank of Israel has avoided making this mistake, but there are undoubtedly voices within the BoI that what monetary policy to be more dependent on the development household debt and property prices (these voices are within all central banks these days…)

That said, the Bank of Israel is far from being the Riksbank and so far the emphasis on property market developments in communication about monetary policy has not been overly problematic, but that could change in the future and if the BoI became more focused on these issues then I fear that that could led to a more fundamental un-anchoring of inflation expectations and therefore a more unstable economic development.

2) Avoid repeating the mistakes of the ECB. While the Riksbank has been preoccupied with property prices the ECB has been preoccupied with fiscal policy. There are some signs that the Bank of Israel is getting a bit too focused on fiscal policy rather than focusing on monetary policy. Hence, Mrs. Flug has recently been in a bit of war of words with Finance Minister Yair Lapid about the public budget deficit (see for example here).

While I have sympathy for Mrs. Flug’s fiscal conservatism it is not really the task of any central bank to have a view on fiscal policy other than just take fiscal policy as an exogenous factor when setting policy instruments to hit the central bank’s target. The Bank of Israel should make this completely clear so market participants do not come to think that the BoI will keep monetary policy overly tight (ECB fashion) to punish the Israeli government for overly easy fiscal policy.

3) Pre-announce what to at the Zero Lower Bound. With the BoI’s key policy rates at 0.25% we are effectively at the Zero Lower Bound (ZLB). It is no secret that (Market) Monetarists like myself don’t think that the ZLB is a binding constraint on the possibility for further easing monetary policy. However, the ZLB is often a mental constraint on monetary policy makers.

I think that most observers of the BoI knows that the BoI does not have major “mental” problem with using other instruments – than the interest rate – to ease monetary. Hence, the BoI has since 2008 both bond quantitative easing by buying government bonds and intervened in the currency market to weaken the Israeli shekel. It could easily do that again and I think most market participants full well knows this. Hence, in that sense Israel is in a much better than for example the euro zone.

However, instead of letting the market guessing what it might do in the future if necessary the BoI should already today announce what instrument it would be using to conduct monetary policy at the ZLB. Personally I think the most suitable “instrument” to use for small open economy is the exchange rate channel either in the way it has been done for years by the Monetary Authority of Singapore (MAS) or in recent years by the Swiss and Czech central banks.

I think the best option would simply be for the BoI to announce that it – if needed – could put a floor under USD/ILS and at the same time announce that it will keep the door open for moving up this floor until inflation expectations on all relevant time horizons are between 2 and 2.5%. That in my view would likely lead to a weakening of the shekel of a magnitude to bring inflation expectations immediately in line with this narrow “target” range.

Karnit Flug doesn’t have an easy job to do, but she has a solid foundation to build on

There is no doubt that there is a risk that Stan Fischer’s achievements as Bank of Israeli governor could be jeopardized. However, Karnit Flug has not failed yet and she still have the opportunity to continue the success of Stan Fischer.

But then this has to focus on bringing back the “straight line policy” and ensuring that inflation expectations do not become un-anchored. Hence, she needs to not allow herself to be distracted by the development in property prices and fiscal policy and instead focus on how to conduct monetary policy in a transparent and efficient way at the Zero Lower Bound.

PS I am well-aware that Stan Fischer no longer officially is a proponent of NGDP level targeting and that the BoI does not have an NGDP level target, but rather an inflation target. However, thing of a NGDP target as an intermediate target to implement the “ultimate” target – the inflation target. If the BoI for example keeps the NGDP level on a 5% path and we assume that potential real GDP growth is 2% then the outcome will be 2% over the cycle.
