LONDON, Feb 1 (Reuters) - Oil prices ticked up as the market is looking towards a meeting of OPEC and its allies as well as a Federal Reserve rate decision and U.S. government data on crude and fuel stockpiles on Wednesday.
Brent crude futures rose 45 cents, or 0.5%, to $85.91 a barrel at 1215 GMT.
West Texas Intermediate (WTI) U.S. crude futures rose 62 cents, or 0.8%, to $79.49 a barrel.
Tamer U.S. rate hike expectations helped lower the dollar index , which supported oil prices as a weaker greenback makes the commodity cheaper for buyers holding other currencies, according to Stephen Brennock, analyst at PVM.
OPEC's oil output fell in January, as Iraqi exports dropped and Nigeria's output did not recover, with the 10 OPEC members pumping 920,000 barrels per day (bpd) below their targeted volumes under the OPEC+ agreement, a Reuters survey found.
