Japan sold yen in the market on Wednesday for the first time in six years and promised more to come in a bid to stop the currency's relentless rise from hurting exporters and threatening a fragile economic recovery.
Even as the U.S. dollar surged as much as 3 percent on the day against the yen, doubts lingered about the ultimate effectiveness of Japan's unilateral yen selling spree. A 15-month solo effort by Switzerland to weaken its currency did little to tame the Swiss franc.
In addition, Japan is trying to put a halt to yen strength while other major central banks such as the Federal Reserve may be considering additional steps to ease policy that could weigh on their respective currencies.
This could be a very significant event, or it could amount to nothing. It is probably only the first of several such sales as Japan tries to keep the Yen from rising too high. There is a lot of question though about Japan's actual ability to keep the Yen down, particularly as other countries are looking at policies to keep their currencies low also. Everybody wants to export their way out of their economic problems.
Japan is also doing this in an unusual way. Normally when a country does this they issue bonds or otherwise takes steps to keep the sudden increase in the number of bills in circulation from causing inflation. Japan isn't doing that here, their local economy has been deflationary for so long that they want to spark some inflation.
