The 16-nation currency bought $1.3046 in Wednesday morning European trading.

That was down from $1.3196 in New York late Tuesday, when the euro had slipped after the Fed announced small-scale plans to buy government debt in an effort to aid the recovery.

The dollar is a traditional safe haven for investors and the latest signal that China's boom is cooling appeared to have reduced their appetite for assets deemed riskier.

The British pound dropped to $1.5770 from $1.5881. The dollar edged up to 85.33 Japanese yen from 85.27 yen.
