The US dollar fell slightly on Thursday currency exchange trading against the euro, ahead of official data expected to show that job growth in the US accelerated during October.

The euro rose to $1.277 from $1.256 on Wednesday, while sterling slipped from $1.9085 to $1.9087. Against the yen, the dollar rose from Y117.06 to Y117.12.

The expectation ahead of the US report overshadowed a statement from European Central Bank (ECB) president Jean-Claude Trichet promising "strong vigilance" on inflation, raising the prospect of an interest rate rise next month.

Analysts expect the US to have added 123,000 jobs in October compared to 51,000 in September. The jobless rate is expected to stay at its five-year low of 4.6 per cent.

"All it would take now is for the report to come in stronger than expectations," Sue Trinh at RBC Capital Markets in Sydney told the International Herald Tribune.

"That's likely to give the dollar a very strong boost."
