The Swiss franc edged lower against the dollar on Tuesday ahead of Swiss export and investor sentiment data due later in the session. The Swiss currency was trading near unchanged at 1.5785 per euro and fell 0.15 percent against the dollar to 1.2261.
On Monday the franc had risen against other major currencies as interest rate expectations weighed on the dollar and the yen. Interest rate differentials have supported the euro rather than franc in past sessions as many investors still expect the European Central Bank to raise interest rates more aggressively than its Swiss counterpart.
But strong growth in some of Switzerland's main export markets like Germany, robust domestic demand and more hawkish comments from SNB Chairman Jean-Pierre Roth have made markets somewhat less convinced the SNB will stick to its steady course.
