Finance ministers and central bank presidents comprising the Group of Seven nations will meet in Washington on Friday. The group - which includes the U.S., Japan, Germany, the U.K. France, Italy and Canada - has not set collective policies for a currency since it came to the aid of the euro in 2000.
On Thursday, the European Central Bank maintained its interest rate steady at 4 percent as expected. ECB President Jean-Claude Trichet signaled the bank was not ready to cut rates, citing high inflation.
The Bank of England dropped its benchmark rate by a quarter point as expected as it deals with the effects of a slumping housing market and troubled credit markets.
