Oil prices have benefited from the Fed's stimulus because it has kept the dollar from strengthening — making oil more affordable for traders using other currencies — and because low interest rates have attracted investors to commodities like crude oil in search of higher profits.
As for supplies, data for the week ended Jan. 24 is expected to show increases of 2.1 barrels in crude oil stocks and 1.6 million barrels in gasoline stocks, according to a survey of analysts by Platts, the energy information arm of McGraw-Hill Cos.
Brent crude, used to set prices for international varieties of crude, rose 72 cents t US$107.41 a barrel on the ICE Futures exchange in London.
