The exchange rate fallacy: Currency war or a race to save the global economy?

This is from CNB.com:

Faced with a stubbornly slow and uneven global economic recovery, more countries are likely to resort to cutting the value of their currencies in order to gain a competitive edge.

Japan has set the stage for a potential global currency war, announcing plans to create money and buy bonds as the government of Prime Minister Shinzo Abe looks to stimulate the moribund growth pace…

Economists in turn are expecting others to follow that lead, setting off a battle that would benefit those that get out of the gate quickest but likely hamper the nascent global recovery and the relatively robust stock market.

This pretty much is what I would call the ‘exchange rate fallacy’ – hence the belief that monetary easing in someway is a zero sum game where monetary easing works through an “unfair” competitiveness channel and one country’s gain is another country’s lose.

Lets take the arguments one-by-one.

“…countries are likely to resort to cutting the value of their currencies in order to gain a competitive edge.”

The perception here is that monetary policy primarily works through a “competitiveness channel” where a monetary easing leads to a weakening of the currency and this improve the competitiveness of the nation by weakening the real value of the currency. The problem with this argument is first of all that this only works if there is no increase in prices and wages. It is of course reasonable to assume that that is the case in the short-run as prices and wages tend to be sticky. However, empirically such gains are minor.

I think a good illustration of this is relative performance of Danish and Swedish exports in 2008-9. When crisis hit in 2008 the Swedish krona weakened sharply as the Riksbank moved to cut interest rates aggressive and loudly welcomed the weakening of the krona. On the other hand Denmark continued to operate it’s pegged exchange rate regime vis-a-vis the euro. In other words Sweden initially got a massive boost to it’s competitiveness position versus Denmark.

However, take a look at the export performance of the two countries in the graph below.

Starting in Q3 2008 both Danish and Swedish exports plummeted. Yes, Swedish dropped slightly less than Danish exports but one can hardly talk about a large difference when it is taken into account how much the Swedish krona weakened compared to the Danish krone.

And it is also obvious that such competitiveness advantage is likely to be fairly short-lived as inflation and wage growth sooner or later will pick up and erode any short-term gains from a weakening of the currency.

The important difference between Denmark and Sweden in 2008-9 was hence not the performance of exports.

The important difference on the other hand the performance of domestic demand. Just have a look at private consumption in Sweden and Denmark in the same period.

It is very clear that Swedish private consumption took a much smaller hit than Danish private consumption in 2008-9 and consistently has grown stronger in the following years.

The same picture emerges if we look at investment growth – here the difference it just much bigger.

The difference between the performance of the Danish economy and the Swedish economy during the Great Recession hence have very little to do with export performance and everything to do with domestic demand.

Yes, initially Sweden gained a competitive advantage over Denmark, but the major difference was that Riksbanken was not constrained in it ability to ease monetary policy by a pegged exchange rate in the same way as the Danish central bank (Nationalbanken) was.

(For more on Denmark and Sweden see my earlier post The luck of the ‘Scandies’)

Hence, we should not see the exchange rate as a measure of competitiveness, but rather as an indicator of monetary policy “tightness”.When the central bank moves to ease monetary policy the country’s currency will tend to ease, but the major impact on aggregate demand will not be stronger export performance, but rather stronger growth in domestic demand. There are of course numerous examples of this in monetary history. I have earlier discussed the case of the Argentine devaluation in 2001 that boosted domestic demand rather exports. The same happened in the US when FDR gave up the gold standard in 1931. Therefore, when journalists and commentators focus on the relationship between monetary easing, exchange rates and “competitiveness” they are totally missing the point.

The ‘foolproof’ way out of deflation

That does not mean that the exchange rate is not important, but we should not think of the exchange rate in any other way than other monetary policy instruments like interest rates. Both can lead to a change in the money base (the core monetary policy instrument) and give guidance about future changes in the money base.

With interest rates effectively stuck at zero in many developed economies central banks needs to use other instruments to escape deflation. So far the major central banks of the world has focused on “quantitative easing” – increasing in the money base by buying (domestic) financial assets such as government bonds. However, another way to increase the money base is obviously to buy foreign assets – such as foreign currency or foreign bonds. Hence, there is fundamentally no difference between the Bank of Japan buying Japanese government bonds and buying foreign bonds (or currency). It is both channels for increasing the money base to get out of deflation.

In fact on could argue that the exchange rate channel is a lot more “effective” channel of monetary expansion than “regular” QE as exchange rate intervention is a more transparent and direct way for the central bank to signal it’s intentions to ease monetary policy, but fundamentally it is just another way of monetary easing.

It therefore is somewhat odd that many commentators and particularly financial journalists don’t seem to realise that FX intervention is just another form of monetary easing and that it is no less “hostile” than other forms of monetary easing. If the Federal Reserve buys US government treasuries it will lead to a weakening of dollar in the same way it would do if the Fed had been buying Spanish government bonds. There is no difference between the two. Both will lead to an expansion of the money base and to a weaker dollar.

“Economists in turn are expecting others to follow that lead, setting off a battle that would benefit those that get out of the gate quickest but likely hamper the nascent global recovery and the relatively robust stock market”

This quote is typical of the stories about “currency war”. Monetary easing is seen as a zero sum game and only the first to move will gain, but it will be on the expense of other countries. This argument completely misses the point. Monetary easing is not a zero sum game – in fact in an quasi-deflationary world with below trend-growth a currency war is in fact a race to save the world.

Just take a look at Europe. Since September both the Federal Reserve and the Bank of Japan have moved towards a dramatically more easy monetary stance, while the ECB has continue to drag its feet. In that sense one can say that that the US and Japan have started a “currency war” against Europe and the result has been that both the yen and the dollar have been weakened against the euro. However, the question is whether Europe is better off today than prior to the “currency war”. Anybody in the financial markets would tell you that Europe is doing better today than half  a year ago and European can thank the Bank of Japan and the Fed for that.

So how did monetary easing in the US and Japan help the euro zone? Well, it is really pretty simple. Monetary easing (and the expectation of further monetary easing) in Japan and the US as push global investors to look for higher returns outside of the US and Japan. They have found the higher returns in for example the Spanish and Irish bond markets. As a result funding costs for the Spanish and Irish governments have dropped significantly and as a result greatly eased the tensions in the European financial markets. This likely is pushing up money velocity in the euro zone, which effectively is monetary easing (remember MV=PY) – this of course is paradoxically what is now making the ECB think that it should (prematurely!) “redraw accommodation”.

The ECB and European policy makers should therefore welcome the monetary easing from the Fed and the BoJ. It is not an hostile act. In fact it is very helpful in easing the European crisis.

If the more easy monetary stance in Japan and US was an hostile act then one should have expected to see the European markets take a beating. That have, however, not happened. In fact both the European fixed income and equity markets have rallied strongly on particularly the new Japanese government’s announcement that it want the Bank of Japan to step up monetary easing.

So it might be that some financial journalists and policy makers are scare about the prospects for currency war, but investors on the other hand are jubilant.

If you don’t need monetary easing – don’t import it

Concluding, I strongly believe that a global “currency war” is very good news given the quasi-deflationary state of the European economy and so far Prime Minister Abe and Fed governor Bernanke have done a lot more to get the euro zone out of the crisis than any European central banker has done and if European policy makers don’t like the strengthening of the euro the ECB can just introduce quantitative easing. That would curb the strengthening of the euro, but more importantly it would finally pull the euro zone out of the crisis.

Hence, at the moment Europe is importing monetary easing from the US and Japan despite the euro has been strengthening. That is good news for the European economy as monetary easing is badly needed. However, other countries might not need monetary easing.

As I discussed in my recent post on Mexico a country can decide to import or not to import monetary easing by allowing the currency to strengthen or not. If the Mexican central bank don’t want to import monetary easing from the US then it can simply allow the peso strengthen in response to the Fed’s monetary easing.

Currency war is not a threat to the global economy, but rather it is what could finally pull the global economy out of this crisis – now we just need the ECB to join the war.

Answering Tyler’s question on Japan with old blog post

Here is Tyler Cowen on Twitter:

Still not seeing much discussion of 4.1% unemployment rate in Japan, would love to see “jump start” defined.

What Tyler is basically saying is that there really is not an argument for “jump starting” the Japanese economy with fiscal and monetary stimulus when unemployment is this low. I many ways I share Tyler’s skepticism about “stimulus” in the case of Japan.

I have long argued that Japanese story is a lot more complicated than it is normally said to be (my first post on the topic was: “Japan’s deflation story is not really a horror story” from October 2011). It is correct that Japan’s lost decade was not a story of two lost decades and in my view quantitative easing ended the “lost decade” in 2001. This is what I said in my post “Japan shows that QE works”

In early 2001 the Bank of Japan finally decided to listen to the advise of Milton Friedman and as the graph clearly shows this is when Japan started to emerge from the lost decade and when real GDP/capita started to grow in line with the other G7 (well, Italy was falling behind…).

The actions of the Bank of Japan after 2001 are certainly not perfect and one can clearly question how the BoJ implemented QE, but I think it is pretty clearly that even BoJ’s half-hearted monetary easing did the job and pull Japan out of the depression. In that regard it should be noted that headline inflation remained negative after 2001, but as I have shown in my previous post Bank of Japan managed to end demand deflation (while supply deflation persisted).

And yes, yes the Bank of Japan of course should have introduces much clearer nominal target (preferably a NGDP level target) and yes Japan has once again gone back to demand deflation after the Bank of Japan ended QE in 2007. But that does not change that the little the BoJ actually did was enough to get Japan growing again.

This graph of GDP/capita in the G7 countries illustrates my point:

g7rgdpcap

As I said in my earlier post: “A clear picture emerges. Japan was a star performer in 1980s. The 1990s clearly was a lost decade, while Japan in the past decade has performed more or less in line with the other G7 countries. In fact there is only one G7 country with a “lost decade” over the paste 10 years and that is Italy.”

Hence, Japan came out of the crisis from 2001. However, it should also be noted that Japan has once again fallen into crisis and more importantly Japan’s monetary policy certainly is not based on a rule based framework so the risk that Japan will continue to fall back into crisis remains high. This in my view is a discussion about securing Japan a “Monetary constitution” rather than about stimulus. Unfortunately Prime Minister Abe’s new government do seem to be more focused on short-term stimulus rather than on real institutional reform.

There is no such thing as fiscal policy

– and that goes for Japan as well

The Abe government is not only pursuing expansionary monetary policies, but has also announced that it wants to ease fiscal policy dramatically. This obviously will scare any Market Monetarist – or anybody who are simply able to realise that there is a budget constrain that any government will have to fulfill in the long-run.

This is what I earlier have said on the fiscal issue in the case of Japan:

Furthermore, it is clear that Japan’s extremely weak fiscal position to a large extent can be explained by the fact that BoJ de facto has been targeting 0% NGDP growth rather than for example 3% or 5% NGDP growth. I basically don’t think that there is a problem with a 0% NGDP growth path target if you start out with a totally unleveraged economy – one can hardly say Japan did that. The problem is that BoJ changed its de facto NGDP target during the 1990s. As a result public debt ratios exploded. This is similar to what we see in Europe today.

So yes, it is obvious that Japan can’t not afford “fiscal stimulus” – as it today is the case for the euro zone countries. But that discussion in my view is totally irrelevant! As I recently argued, there is no such thing as fiscal policy in the sense Keynesians claim. Only monetary policy can impact nominal spending and I strongly believe that fiscal policy has very little impact on the Japanese growth pattern over the last two decades.

Above I have basically added nothing new to the discussion about Japan’s lost decade (not decades!) and fiscal and monetary policy in Japan, but since Scott brought up the issue I thought it was an opportunity to remind my readers (including Scott) that I think that the Japanese story is pretty simple, but also that it is wrong that we keep on talking about Japan’s lost decades. The Japanese story tells us basically nothing new about fiscal policy (but reminds us that debt ratios explode when NGDP drops), but the experience shows that monetary policy is terribly important.

My advise: Target an 3% NGDP growth level path and balance the budget 

My advise to the Abe government would therefore be for the Bank of Japan to introduce proper monetary policy rules and I think that an NGDP level targeting rule targeting a growth path of 3% would be suiting for Japan given the negative demographic outlook for Japan. Furthermore, if the BoJ where to provide a proper framework for nominal stability then the Japanese government should begin a gradual process of fiscal consolidation by as soon as possible to bring the Japanese budget deficit back to balance. With an NGDP growth path of 3% Japanese public debt as a share of GDP would gradually decline in an orderly fashion on such fiscal-monetary framework.

So what Japan needs is not “stimulus” – neither fiscal nor monetary – but rather strict rules both for monetary policy and fiscal policy. The Abe government has the power to ensure that, but I am not optimistic that that will happen.

PS even though I am skeptical about the way Shinzo Abe are going about things and I would have much preferred a rule based framework for Japan’s monetary and fiscal policy I nonetheless believe that the Abe government’s push for particularly monetary “stimulus” is likely to spur Japanese growth and is very likely to be good news for a global economy badly in need of higher growth.

Update: Scott Sumner also comments on Japan and it seems like we have more or less the same advise. Here is Scott:

“Just to be clear, my views are somewhere between those of Feldstein and the more extreme Keynesians.  I agree with Feldstein that Japan has big debt problems and big structural problems, and needs to address both.  And that fiscal stimulus is foolish (as even Adam Posen recently argued.)  Unlike Feldstein I also think they have an AD problem that calls for modestly higher inflation and NGDP growth.  At a minimum they should be shooting for 2% to 3% NGDP growth, instead of the negative NGDP growth of the past 20 years.”

Ambrose on Abe

Here is our friend Ambrose Evans-Pritchard in the Daily Telegraph:

Japan’s incoming leader Shinzo Abe has vowed to ram through full-blown reflation policies to pull his country out of slump and drive down the yen, warning Japan’s central bank not to defy the will of the people.

…The profound shift in economic strategy by the world’s top creditor nation could prove a powerful tonic for the global economy, with stimulus leaking into bourses and bond markets – a variant of the “carry trade” earlier this decade but potentially on a larger scale.

…”It is tremendously important for global growth, and markets are starting to take note,” said Lars Christensen from Danske Bank.

Mr Abe’s Liberal Democratic Party (LDP) won a landslide victory on Sunday, securing a two-thirds “super-majority” in the Diet with allies that can override senate vetoes.

Armed with a crushing mandate, Mr Abe said he would “set a policy accord” with the Bank of Japan for a mandatory inflation target of 2pc, backed by “unlimited” monetary stimulus.

“Its very rare for monetary policy to be the focus of an election. We campaigned on the need to beat deflation, and our argument has won strong support. I hope the Bank of Japan accepts the results and takes an appropriate decision,” he said.

Mr Abe plans to empower an economic council to “spearhead” a shift in fiscal and monetary strategy, eviscerating the central bank’s independence.

The council is to set a 3pc growth target for nominal GDP, embracing a theory pushed by a small band of “market monetarists” around the world. “This is a big deal. There has been no nominal GDP growth in Japan for 15 years,” said Mr Christensen.

Did I just say that NGDP hasn’t grown for 15 years in Japan? Yes, I did…it is actually worse – Japanese nominal GDP is 10% lower today than in 1997.

NGDP Japan

The ECB is the only one of the major central banks in the world that is not at the moment taking decisive steps in the direction of getting out of the deflationary scenario. I hope we don’t have to wait 15 years for the ECB to do the right thing. The Japanese experience should be a major warning to European policy makers.

If you don’t think you can compare Europe today and Japan in 1997 then maybe you should should take a look at this post.

PS a friend of mine who once spent time at the BoJ is telling me not to get overly optimistic…

PPS Matt Yglesias also comments on Abe.

BoJ might become the first central bank in the world to introduce NGDP targeting

I stole this from Britmouse (who got it from Bloomberg):

Abe advocates increased monetary easing to reverse more than a decade of falling prices and said he would consider revising a law guaranteeing the independence of the Bank of Japan. (8301) In an economic policy plan issued yesterday, the LDP said it would pursue policies to attain 3 percent nominal growth.

Talk about good news! Shinzo Abe of course is the leader of Japan’s main opposition party the Liberal Democratic Party (LDP). LDP is favourite to win the upcoming Japanese parliament elections – so soon Japan might have a Prime Minister who favours NGDP targeting.

So how could this be implemented? Well, Lars E. O. Svensson has a solution and I am pretty sure he would gladly accept the job if Abe offered him to become new Bank of Japan governor. After all he does not seem to happy with his colleagues at the Swedish Riksbank at the moment.

PS I would love to get in contact with any Japanese economist interested in NGDP targeting – please drop me a mail (lacsen@gmail.com)

Update: Oops – Scott also comments on this story.

The ECB is turning into the BoJ

This is ECB Chief Mario Draghi:

“Well, let me first just point out that I never mentioned deflation. Deflation is a generalised fall in the price level across sectors and it is self-sustaining. And so far we have not seen signs of deflation, neither at the euro area level nor at country level. We should also be very careful about not mixing up what is a normal price readjustment due to the restoration of competitiveness in some of these countries. They will necessarily have to go through a re-adjustment of prices. We should not confuse this readjustment of prices, which is actually welcome, with deflation. Basically, we see price behaviour in line with our medium-term objectives. So, we see price stability over the medium term. Also consider that monetary policy is already very accommodative, consider the very low level of interest rates and that real interest rates are negative in a large part of the euro area…”

When I read Draghi’s comments the first thing I came to think of was how much this sounds like comments from Bank of Japan officials over the last 15 years.

Maybe Mario Draghi would be interested in this graph. It show the growth of broad money in the euro zone and Japan. I have constructed the graph so the growth of money peaks more or less at the same time in the graph for Japan and the euro zone. M2 growth peaked around 1990 in Japan and 2008 in the euro zone. The graph clearly shows both the boom and the bust and for Japan a very long period – more than a decade – of very low money supply growth.

I basically hate this kind of graph but the similarity is hard to miss. If Mario Draghi thinks euro zone monetary policy is “accommodative” today then he would also have to think Japanese monetary policy was accommodative in 1994-94.

BUT worse if the ECB continues on it’s present path it will likely repeat the mistakes of the BoJ and then we might be in for years of deflation. I know that this is not what Draghi wants, but the ECB’s present policy is unfortunately not giving much hope that a Japanese scenario can be avoided.

By the way that is the real reason for the slump we are seeing in global stock markets these days and it likely has very little to do with Obama’s reelection and the fear of the “fiscal cliff”. It is mostly about the escalation of bad news out of Europe. I hope Draghi will soon realize that unless he shows some Rooseveltian Resolve then the bad news will continue for another decade.

Chuck Norris just pushed S&P500 above 1400

Today S&P500 closed above 1400 for the first time since June 2008. Hence, the US stock market is now well above the levels when Lehman Brothers collapsed in October 2008. So in terms of the US stock market at least the crisis is over. Obviously that can hardly be said for the labour market situation in the US and most European stock markets are still well below the levels of 2008.

So what have happened? Well, I think it is pretty clear that monetary policy has become more easy. Stock prices are up, commodity prices are rising and recently US long-term bond yields have also started to increase. As David Glasner notices in a recent post – the correlation between US stock prices and bond yields is now positive. This is how it used to be during the Great Moderation and is actually an indication that central banks are regaining some credibility.

By credibility I mean that market participants now are beginning to expect that central banks will actually again provide some nominal stability. This have not been directly been articulated. But remember during the Great Moderation the Federal Reserve never directly articulated that it de facto was following a NGDP level target, but as Josh Hendrickson has shown that is exactly what it actually did – and market participants knew that (even though most market participants might not have understood the bigger picture). As a commenter on my blog recently argued (central banks’) credibility is earned with long and variable lags (thank you Steve!). Said in another way one thing is nominal targets and other thing is to demonstrate that you actually are willing to do everything to achieve this target and thereby make the target credible.

Since December 8 when the ECB de facto introduced significant quantitative easing via it’s so-called 3-year LTRO market sentiment has changed. Rightly or wrongly market participants seem to think that the ECB has changed it’s reaction function. While the fear in November-December was that the ECB would not react to the sharp deflationary tendencies in the euro zone it is now clear that the ECB is in fact willing to ease monetary policy. I have earlier shown that the 3y LTRO significantly has reduced the the likelihood of a euro blow up. This has sharply reduced the demand for save haven currencies – particularly for the US dollars, but also the yen and the Swiss franc. Lower dollar demand is of course the same as a (passive) easing of US monetary conditions. You can say that the ECB has eased US monetary policy! This is the opposite of what happened in the Autumn of 2010 when the Fed’s QE2 effectively eased European monetary conditions.

Furthermore, we have actually had a change in a nominal target as the Bank of Japan less than a month ago upped it’s inflation target from 0% to 1% – thereby effectively telling the markets that the bank will step up monetary easing. The result has been clear – just have a look at the slide in the yen over the last month. Did the Bank of Japan announce a massive new QE programme? No it just called in Chuck Norris! This is of course the Chuck Norris effect in play – you don’t have to print money to see monetary policy if you are a credible central bank with a credible target.

So both the ECB and the BoJ has demonstrated that they want to move monetary policy in a more accommodative direction and the financial markets have reacted. The markets seem to think that the major global central banks indeed want to avoid a deflationary collapse and recreate nominal stability. We still don’t know if the markets are right, but I tend to think they are. Yes, neither the Fed nor the ECB have provide a clear definition of their nominal targets, but the Bank of Japan has clearly moved closer.

Effective the signal from the major global central banks is yes, we know monetary policy is potent and we want to use monetary policy to increase NGDP. This is at least how market participants are reading the signals – stock prices are up, so are commodity prices and most important inflation expectations and bond yields are increasing. This is basically the same as saying that money demand in the US, Europe and Japan is declining. Lower money demand equals higher money velocity and remember (if you had forgot) MV=PY. So with unchanged money supply (M) higher V has to lead to higher NGDP (PY). This is the Chuck Norris effect – the central banks don’t need to increase the money base/supply if they can convince market participants that they want an higher NGDP – the markets are doing all the lifting. Furthermore, it should be noted that the much feared global currency war is also helping ease global monetary conditions.

This obviously is very good news for the global economy and if the central banks do not panic once inflation and growth start to inch up and reverse the (passive) easing of monetary policy then it is my guess we could be in for a rather sharp recovery in global growth in the coming quarters. But hey, my blog is not about forecasting markets or the global economy – I do that in my day-job – but what we are seeing in the markets these days to me is a pretty clear indication of how powerful the Chuck Norris effect can be.  If central banks just could realise that and announced much more clear nominal targets then this crisis could be over very fast…
