LONDON, March 29 (Reuters) - Oil prices rose more than $2 a barrel on Monday, supported by a weaker dollar and economic optimism as strong data pushed U.S. equities higher.
The dollar index <.DXY> fell nearly half a percent against a basket of currencies on Monday, increasing risk appetite and boosting commodity prices, including oil.
U.S crude for May <CLc1> delivery rose $1.94 to $81.94 a barrel by 1358 GMT. The contract settled down 53 cents at $80.00 per barrel on Friday, bringing weekly losses to 0.84 percent.
London Brent crude <LCOc1> gained $1.77 to $81.06.
"Oil is moving on the dollar," said Eugen Weinberg, oil analyst at Commerzbank in Frankfurt.
"Equity markets are also higher but the dollar is much weaker against the euro and that is dragging all commodities higher," Weinberg added.
Strong U.S. and European economic data and robust Asian indicators helped to lift equity markets and raise oil market sentiment. [
