LONDON, Nov 10 (Reuters) - The dollar's trade-weighted index hovered near a 15-month low on Tuesday on the view U.S. interest rates will stay low, while sterling fell after Fitch said the UK was the major economy most at risk of losing its AAA rating.

Analysts said investors lacked any catalyst to take the dollar much lower after its recent sharp falls, but they said the trend towards dollar weakness remained in place.

The euro quickly reversed an initial dip after a weaker-than-expected German ZEW survey showed investors more gloomy than at any time in the last four months. [ID:nLA641918]
