Crude oil futures rose early on Tuesday, pushed up by a weaker dollar and a flood of new cash into the market, but analysts warned that fundamentals remain weak as a producer race for customers heats up in the Middle East.
Front-month Brent crude futures were trading at $44.84 per barrel at 0054 GMT, up 36 cents from their last settlement, and U.S. crudefutures gained 39 cents at $43.03.
