The Swiss franc softened a touch against the dollar on Wednesday, after the Swiss National Bank (SNB) said interest rates were at a "comfortable" level, signalling no rush to raise borrowing costs again. The dollar traded at 1.2303/07 francs in early European business, up from levels around 1.2283/88 late on Tuesday. The euro last changed hands at 1.5378/92, little changed from 1.5383/88. The Swiss central bank has cranked up interest rates twice this year from ultra-low levels to target 0.75 percent amid an economic pick-up. But it has now signalled it may not be in a hurry to again tighten monetary reins. "Having increased the interest rate by 50 basis points, we are in a comfortable position," SNB Chairman Jean-Pierre Roth told reporters on the sidelines of a British-Swiss Chamber of Commerce meeting. Swiss franc futures jumped on the news, scaling back expectations of a third rate hike in December. The dollar firmed against the euro on Tuesday after a report on U.S. consumer prices showed core inflation was stronger than expected in September, but later fell against most major currencies as dealers still fretted about the U.S. economy.///
