Oil languishes near multi-month lows on glut fears

By Aaron Sheldrick

TOKYO (Reuters) - Oil prices held near multi-month lows on Wednesday as investors discounted evidence of strong compliance by OPEC and non-OPEC oil producers with a deal to cut a global output.

Global benchmark Brent was unchanged at $46.02 barrel at 0651 GMT after falling nearly 2 percent in the previous session to its lowest settlement since November.

U.S. crude futures for August were trading up 4 cents at $43.55, after spending much of the day slightly lower and falling more than 2 percent on Tuesday to the lowest since September.

Compliance with an agreement by the Organization of the Petroleum Exporting Countries and other producers to cut output by 1.8 million barrels per day (bpd) for six months from January reached its highest in May since curbs were agreed last year.

"The lack of a positive response in oil prices clearly suggests market participants are not convinced that the OPEC's efforts will help shore up prices in a meaningful way in the short-term as shale supply continues to rise in the U.S.," said Fawad Razaqzada, market analyst at futures brokerage Forex.com.

"Unless we see a marked reduction in crude stockpiles, the possibility of further short term falls in the price of oil cannot be ruled out," he added.

The American Petroleum Institute said on Tuesday U.S. crude stockpiles had dropped more than forecast. U.S. crude stocks fell last week, while gasoline and distillate inventories rose.

A government report is due at 10:30 a.m. EDT (1430 GMT) on Wednesday and the official figures often differ sharply from those of the industry group.

OPEC and non-OPEC oil producers' compliance with the output deal reached 106 percent in May, a source familiar with the matter said on Tuesday.

OPEC compliance with the output curbs in May was 108 percent, while non-OPEC compliance was 100 percent, the source said. Another source confirmed compliance by all producers in May was 106 percent.

While compliance is high, it is what went on before the production cut that counts, BMI Research said in a note.

"A number of producers - notably Iraq, Saudi Arabia and Russia - aggressively ramped up output in the run up to the deal, fast-tracking projects, expanding drilling programmes and deploying spare capacity," BMI said.

Thus the production cut is not costless and "should prices relapse again, OPEC has much less in its arsenal with which to respond."
