The euro slipped Wednesday against the dollar as investors awaited the results of Washington's "stress tests" of the viability of top US banks while the pound weakened ahead of the British budget.
The European single currency fell to 1.2924 dollars from 1.2950 dollars late in New York on Tuesday.
Against the Japanese currency, the dollar declined to 98.26 yen from 98.69 yen on Tuesday.

Investors were waiting for the results of Washington's test of the health of the top 19 US banks to see if more government aid will be needed to keep the US financial system afloat, analysts said.

The euro rose on Tuesday after Germany's ZEW economic sentiment index posted its first positive reading since July 2007, pointing to a possible pickup in the eurozone's largest economy in the second half of 2009.
In recent months, the dollar and yen have benefited from "risk aversion" during times of market turmoil, while the euro is seen as more vulnerable to the economic downturn.
A US blog said leaked results of the stress tests showed 16 of the 19 banks to be "technically insolvent." Although this was denied by the US Treasury, dealers said it was affecting sentiment.
The market appeared to shrug off Japanese trade data suggesting that an export slump eased in March, even though overseas demand remained very weak.
