A VIA INEVITÁVEL

As desvalorizações competitivas já começaram.
A inflação segue dentro de algum tempo.

Beggar, then sneakily enrich, thy neighbour

AMONG today's big news items is the word that Japan is now actively selling yen in order to improve its exchange rate against other major currencies. The yen has risen sharply in recent months, dealing a blow to Japanese exporters and slowing Japanese recovery. The move has led to some fretting that a period of competitive devaluation is nigh. Here's Tim Duy, for instance:

What it all boils down to is this: There apparently is no motivation for global central banks to stop directing capital inflows at the US in an effort to support mercantilist objectives. If it isn’t China, it will be some other economy. And equally apparent, there is no motivation among US policymakers to address such government directed capital flows. Which will leave politicians falling back on ultimately harmful trade barriers. The absolute inability of US policymakers to seriously address a global financial architecture where a rule of the game is "when in doubt, by Dollars" will ultimately have serious consequences via disruptive adjustment when the system can no longer be maintained, via either external or internal forces.

Doom and gloom, but I feel more positive about this development. Consider Buttonwood's take:

As David Bloom of HSBC points out in a note responding to the move, the costs of intervention to the Japanese are not great. Selling yen and buying dollars results in more yen being created, which might be inflationary, but a bit of Japanese inflation wouild be a good thing.

My thought concerns the general tendency of countries to want their currencies to depreciate. Everyone would like to boost their growth by letting their currencies slide and increasing exports. Of course, not all can succeed. Someone must increase net imports and let their currency appreciate. The obvious candidate is the Chinese, but they are unwilling to let it happen (at least at a pace desired by the rest of the world).

The result is like a game of deflationary pass the parcel in which the countries with appreciating currencies eventually feel the pressure, and try to reverse the trend.

A bit of inflation in Japan wouldn't just be a good thing. It would be a really, really great thing. And if other countries react to Japan's intervention by attempting to print and sell their own currencies in order to toss the deflationary potato to someone else, well then so much the better. As the chart at right indicates, its a rare rich economy that couldn't use a bit more inflation.

Not every country can simultaneously depreciate its currency. But everyone can nonetheless benefit from the attempt, if currency interventions lead to expanded money supplies and rising inflation expectations.

It's worth looking again at this important chart:
