The euro continued to scratch back against the U.S. dollar Wednesday after dropping the day before on pessimism about the European Union and speculation the 12-nation euro-zone would cut interest rates. The euro was trading at US$1.2175 early in Europe, up from US$1.2153 in late New York trading on Tuesday. The dollar was mixed against other currencies, with the British pound rising to US$1.8283 from US$1.8271 on Tuesday and the dollar buying 108.51 Japanese yen, up from 108.30.
