Currency Wars: The Next Generation

I saw an interesting news story on the Bloomberg website today. The title sums it up pretty well. “Currency Wars Evolve With Goal of Avoiding Deflation.” Just as Lars Christensen predicted recently, nervous — and misguided — talk about currency wars is spreading fast. Here’s what it says on Bloomberg:

Currency wars are back, though this time the goal is to steal inflation, not growth.

Brazil Finance Minister Guido Mantega popularized the term “currency war” in 2010 to describe policies employed at the time by major central banks to boost the competitiveness of their economies through weaker currencies. Now, many see lower exchange rates as a way to avoid crippling deflation.

Now, as I have pointed out many times (e.g., here, here, and most recently here), “currency war” in the sense used by Mantega, also known as “currency manipulation” or “exchange-rate protection” involves the simultaneous application of exchange-rate intervention by the monetary authority to reduce the nominal exchange rate together with a tight monetary policy aimed at creating a chronic domestic excess demand for money, thereby forcing domestic households and businesses to restrict expenditure to build up their holdings of cash to desired levels, resulting in a chronic balance of payments surplus and the steady accumulation of foreign-exchange reserves by the central bank. So the idea that quantitative easing had anything to do with “currency war” in this sense was a nonsensical notion based on a complete failure to understand the difference between a nominal and a real exchange rate.

“This beggar-thy-neighbor policy is not about rebalancing, not about growth,” David Bloom, the global head of currency strategy at London-based HSBC Holdings Plc, which does business in 74 countries and territories, said in an Oct. 17 interview. “This is about deflation, exporting your deflationary problems to someone else.”

Bloom puts it in these terms because, when one jurisdiction weakens its exchange rate, another’s gets stronger, making imported goods cheaper. Deflation is a both a consequence of, and contributor to, the global economic slowdown that’s pushing the euro region closer to recession and reducing demand for exports from countries such as China and New Zealand.

Well, by definition of an exchange rate (a reciprocal relationship) between two currencies, if one currency appreciates the other depreciates correspondingly. If the euro depreciates relative to the dollar, prices of the same goods will rise measured in euros and fall measured in dollars. The question is what has been causing the euro to depreciate relative to the dollar. The notion of a currency war is meaningless if the change in exchange rates is not at least in part being driven by a deliberate policy choice. So what kind of policy choices are we talking about?

Bank of Japan Governor Haruhiko Kuroda said last month he’d welcome a lower exchange rate to help meet his inflation target and may extend the nation’s unprecedented stimulus program to achieve that. Like his Japanese counterpart, European Central Bank President Mario Draghi has acknowledged the need for a weaker euro to avoid deflation and make exports more competitive, though he’s denied targeting the exchange rate specifically.

After the Argentine peso, which is plunging following a debt default and devaluation, the yen will be the biggest loser among major currencies by the end of 2015, according to median strategist forecasts compiled by Bloomberg as of yesterday. A 6 percent decline is predicted, which would build on a 5.5 percent slide since June.

The euro is also expected to be among the 10 biggest losers, with strategists seeing a 4.8 percent drop. The yen traded at 107.21 per dollar 10:18 a.m. in New York, while the euro bought $1.2658.

Notice that there is no mention of the monetary policy that goes along with the exchange-rate target. Since the goal of the monetary policy is to produce inflation, one would imagine that the mechanism is monetary expansion. If the Japanese and the Europeans want their currencies to depreciate against the dollar, they can intervene in foreign-exchange markets and buy up dollars with newly printed euros or yen. That would tend to cause euros and yen to depreciate against the dollar, but would also tend to raise prices of goods in terms of euros and yen. How does that export deflation to the US?

At 0.3 percent in September, annual inflation in the 18-nation bloc remains a fraction of the ECB’s target of just under 2 percent. Gross-domestic-product growth flat-lined in the second quarter, while Germany, Europe‘s biggest economy, reduced its 2014 expansion forecast this month to 1.2 percent from 1.8 percent.

Disinflationary pressures in the euro area are starting to spread to its neighbors and biggest trading partners. The currencies of Switzerland, Hungary (HUCPIYY), Denmark, the Czech Republic and Sweden are forecast to fall from 3.8 percent to more than 6 percent by the end of next year, estimates compiled by Bloomberg show, partly due to policy makers’ actions to stoke prices.

“Deflation is spilling over to central and eastern Europe,” Simon Quijano-Evans, the London-based head of emerging-markets research at Commerzbank AG, said yesterday by phone. “Weaker exchange rates will help” them tackle the issue, he said.

Hungary and Switzerland entered deflation in the past two months, while Swedish central-bank Deputy Governor Per Jansson last week blamed his country’s falling prices partly on rate cuts the ECB used to boost its own inflation. A policy response may be necessary, he warned.

If the Swedish central bank thinks that it is experiencing deflation, it has tools with which to prevent deflation from occurring. It is bizarre to suggest that a rate cut by ECB could be causing deflation in Sweden.

While not strictly speaking stimulus measures, the Swiss, Danish and Czech currency pegs — whether official or unofficial — have a similar effect by limiting gains versus the euro.

The Swedes could very easily adopt a similar currency peg to avoid any appreciation of the Swedish krona against the euro.

Measures like these are necessary because, even after a broad-based dollar rally, eight of the Group of 10 developed-nation currencies remain overvalued versus the dollar, according to a purchasing-power parity measure from the Organization for Economic Cooperation & Development.

If these currencies are overvalued relative to the dollar, according to a PPP measure, they are under deflationary pressure even at current exchange rates. That means that exchange rate depreciation via monetary expansion is essential to counteracting deflationary pressure.

The notion that exchange-rate depreciation to avoid deflation is a beggar-thy-neighbor policy or a warlike act could not be more wrong. If exchange-rate depreciation by one country causes retaliation by other countries that try to depreciate their currencies even more, that would be a virtuous cycle, not a vicious one.

In his book Trade Depression and the Way Out, Hawtrey summed it up beautifully over 80 years ago, as I observed in this post.

In consequence of the competitive advantage gained by a country’s manufacturers from a depreciation of its currency, any such depreciation is only too likely to meet with recriminations and even retaliation from its competitors. . . . Fears are even expressed that if one country starts depreciation, and others follow suit, there may result “a competitive depreciation” to which no end can be seen.

This competitive depreciation is an entirely imaginary danger. The benefit that a country derives from the depreciation of its currency is in the rise of its price level relative to its wage level, and does not depend on its competitive advantage. If other countries depreciate their currencies, its competitive advantage is destroyed, but the advantage of the price level remains both to it and to them. They in turn may carry the depreciation further, and gain a competitive advantage. But this race in depreciation reaches a natural limit when the fall in wages and in the prices of manufactured goods in terms of gold has gone so far in all the countries concerned as to regain the normal relation with the prices of primary products. When that occurs, the depression is over, and industry is everywhere remunerative and fully employed. Any countries that lag behind in the race will suffer from unemployment in their manufacturing industry. But the remedy lies in their own hands; all they have to do is to depreciate their currencies to the extent necessary to make the price level remunerative to their industry. Their tardiness does not benefit their competitors, once these latter are employed up to capacity. Indeed, if the countries that hang back are an important part of the world’s economic system, the result must be to leave the disparity of price levels partly uncorrected, with undesirable consequences to everybody. . . .

The picture of an endless competition in currency depreciation is completely misleading. The race of depreciation is towards a definite goal; it is a competitive return to equilibrium. The situation is like that of a fishing fleet threatened with a storm; no harm is done if their return to a harbor of refuge is “competitive.” Let them race; the sooner they get there the better.

The only small quibble that I have with Hawtrey’s discussion is his assertion that a fall in the real wage is necessary to restore equilibrium. A temporary fall in real wages may be part of the transition to equilibrium, but that doesn’t mean that the real wage at the end of the transition must be less than it was at the start of the process.

About Me

David Glasner
Washington, DC

I am an economist in the Washington DC area. My research and writing has been mostly on monetary economics and policy and the history of economics. In my book Free Banking and Monetary Reform, I argued for a non-Monetarist non-Keynesian approach to monetary policy, based on a theory of a competitive supply of money. Over the years, I have become increasingly impressed by the similarities between my approach and that of R. G. Hawtrey and hope to bring Hawtrey's unduly neglected contributions to the attention of a wider audience.
