LONDON (Reuters) - Oil prices fell to their lowest levels in a month on Thursday as the dollar resumed a 10-day rally, making fuel more expensive for holders of other currencies.
The dollar has risen more than 4 percent against a basket of currencies <.DXY> over the last 10 days, helping accelerate a fall in oil prices from a five-month high early in May.
The dollar spiked after a stronger-than-expected rise in U.S. pending homes sales in April, traders said.
"Much depends on the U.S. dollar," said Carsten Fritsch, senior oil and commodities analyst at Commerzbank in Frankfurt.

Investors awaited data from the U.S. Energy Information Administration (EIA) to see how American oil production was responding to a recent surge in prices.

If that is confirmed by EIA figures due at 11 a.m EDT (1500 GMT), it could mean U.S. shale oil production has begun to recover after a brief period of contraction, adding extra pressure to prices.
"The market is trying to anticipate what's going to happen tonight," Phillips Futures analyst Daniel Ang said.

U.S. crude received some support from Canadian wildfires that forced the evacuation of several oil and gas sands production sites on Wednesday.
The fires have caused energy companies operating in Alberta, the largest source of U.S. oil imports, to shut in 233,000 barrels per day of production, or roughly 10 percent of total Canadian oil sands output.
