Oil rises on U.S. crude drawdown hopes, Wall Street rally

By Barani Krishnan

NEW YORK (Reuters) - Oil prices rose on Tuesday as investors anticipated a weekly drawdown in U.S. crude inventories that they hoped would boost prices closer to $50 a barrel, while a rally on Wall Street also lent support.

"We're gearing up on expectations that the wildfires in Canada may finally be showing up in U.S. crude inventory numbers," said Phil Flynn, analyst at the Price Futures Group in Chicago. "If they show up decisively, it may be what the market needs to test $50."

Commercial crude stocks in the United States likely fell by around 2.5 million barrels to 538.8 million in the week ended May 20, a Reuters poll showed.

Oil also got a lift as U.S. equities rose to their highest in the last seven sessions, helped by gains in technology and financial stocks. [.N] Crude buyers seemed unfazed by a stronger dollar <.DXY>, which typically makes greenback-denominated oil costlier in other currencies. <EUR=> [.N] [USD/]

The American Petroleum Institute (API), a trade group, will issue its own data on U.S. crude stockpiles at 4:30 p.m. EDT (2030 GMT), ahead of official numbers from the U.S. government on Wednesday.

U.S. crude's West Texas Intermediate (WTI) futures <CLc1> rose 48 cents, or 1 percent, to $48.56 by 12:32 p.m. EDT. Brent crude futures <LCOc1> rose 28 cents, or 0.6 percent, to $48.63. Both have traded in a $5 range below $50 over the past month.

Oil was also supported by an Iraqi official's remarks that maintenance issues and power outages have caused the OPEC member's output to fall to 4.5 million barrels per day from January's record high of 4.78 million bpd.

Consultant IHS said just 2.8 billion barrels of oil were discovered outside North America in 2015 following a sharp fall in exploration and appraisal drilling. It was the lowest total since 1952. Morgan Stanley said in a separate report the figure would be 12.1 billion barrels if it included the United States.

"As spare capacity dwindles, the threat of a price spike increases," said Matt Smith, who tracks crude cargoes for New York-based Clipperdata. "Non-OPEC production should continue to fall through the duration of the year, gradually erasing the supply overhang and further tightening up crude fundamentals."

Offsetting some positive sentiment in oil, a strike in France dented European crude demand as picketers disrupted refinery operations. Police used water cannon and tear gas to break up a strike that blocked access to a large oil refinery in the southern port area of Marseille.
