The Swiss franc was trading virtually unchanged against the dollar and the euro on Wednesday after dovish comments from the Federal Reserve which suggested a U.S. rate increase could be less aggressive than expected. The U.S. currency traded at 1.2494/98 compared with 1.2503/08 late on Tuesday in Europe. The euro was trading at 1.5173/78 compared with 1.5172/85 late on Tuesday. The dollar dipped in the previous session after Federal Reserve Chairman Alan Greenspan did not appear to dispel the view that an interest rate hike at the end of this month would more likely be 25 basis points than 50 basis points. This view of a modest hike was reinforced by tame U.S. inflation data. Dealers have been watching Fed comments in the run-up to the Swiss National Bank's quarterly policy review on Thursday. The SNB is expected to leave rates on hold at record low levels despite market rates pricing in a 25 basis point rate rise.///
