The Swiss franc eased against the dollar in early Tuesday trading, following in the euro's footsteps after the European Central Bank registered its growing concern over the dollar's recent weakness. The dollar last traded at 1.1819/23 francs, compared to levels around 1.1780/85 francs late on Monday. The euro changed hands at 1.5267/78 francs against 1.5264/69 francs.
Traders said the market was now eyeing key US trade data and the Federal Reserve's decision on interest rates for further direction on the dollar.
The Fed is expected to raise short-term interest rates by a quarter percentage point on Wednesday, which could lend short-term support to the dollar.
The dollar had hit a more-than-eight year low of 1.1761 francs on Monday amid concern over the large US account deficit.
