The Swiss franc fell against the dollar on Wednesday, in line with other major currencies, after the Federal Reserve held rates steady after a two-year string of non-stop increases.
The Fed held rates at 5.25 percent and left the door open to more credit tightening if price pressures persist. Against the euro, the franc weakened slightly amid speculation that the European Central Bank will continue to raise rates and ahead of Thursday's release of Swiss quarterly consumer confidence data for July.
The data are expected to show a strong increase in the index to a reading of +10.8 versus +7.0 in April as economic growth and low unemployment buoy sentiment, according to the median result of a Reuters poll of eight economists. The franc traded 0.1 percent lower at 1.5743 per euro and 0.26 percent lower versus the dollar at 1.226 per dollar.
