The Bank of Japan began the effort with the European Central Bank, Bank of England, Bank of France, Germany’s Bundesbank and the Italian central bank joining in the effort when their markets opened, according to Bloomberg News.
After a conference call on Thursday evening, finance ministers of the Group of Seven industrialized nations pledged “solidarity” with Japan and said that a recent run-up in the value of the yen led them to decide on a “concerted intervention in exchange markets” to try to stabilize the value of the currency.
The yen touched a historic high of about 76 to the dollar this week as markets anticipated a rush of money into the country to fund reconstruction, insurance payments and other needs following the earthquake, tsunami and lingering crisis over the state of several nuclear reactors. The rise in the value of the yen is of concern because an expensive currency might undercut the country’s export industries and make it more difficult for Japan to avoid a return to recession.
No target rate for the yen was given, and it is not clear how aggressive the participating countries will have to become to prevent it from rising in value or to bring it back in line with pre-crisis levels. The fact that the United States, the United Kingdom, Canada and the European Central Bank are ready to sell or buy yen as needed may be enough to change market dynamics. The statement is also important because it gives the Bank of Japan a freer hand to intervene on its own, without worrying that its moves might be criticized as part of a “currency war.”
The United States and other major economic powers typically argue for free-floating exchange rates — and have particularly criticized China for controlling the value of its currency to support its export industries. However, there was clear concern in the G-7 statement that the recent sharp movements in the yen’s value could have unintended consequences for a world economy that is still mending from the recent financial crisis and recession. The last time a similar action took place was more than a decade ago, when efforts were made to support the value of the recently introduced euro.
“Excess volatility and disorderly movements in exchange rates have adverse implications for economic and financial stability,” said a statement released by the group. The statement said that Japan had requested the assistance.
“We will monitor exchange markets closely and will cooperate as appropriate.”
On Thursday, the stock market rose in the United States and much of the world, offering a day of relative calm in a week roiled by calamitous developments in Japan.
