SINGAPORE, May 12 (Reuters) - Oil fell for a second straight day on Wednesday to trade below $76 on mounting concern that emerging economies would fail to compensate for potential consumption declines triggered by Europe's debt crisis.
Accelerating inflation has increased pressure on China, the world's second-largest oil user, to tighten monetary policy and let the yuan appreciate against the dollar, while top consumer the United States is facing a crude glut at the Cushing, Oklahoma, pricing point.
"We cannot depend on China to continue to support the world economy with an EU failure," said Keichi Sano, general manager of research at SCM Securities in Tokyo.
China should raise benchmark deposit rates as a defensive move to stabilise inflation expectations, a central bank adviser said in comments published on Wednesday. [
]"China's power to push back the negative economic impact from the EU is not so strong because they want to slowdown economic growth and raise interest rates to deter inflationary pressure," SCM's Sano said.
U.S. crude for delivery in June <CLc1> tumbled as much as 94 cents to $75.42 a barrel and was down 76 cents at $75.61 at 0658 GMT. That was about $4.50 lower than front-month ICE Brent futures <LCOc1>, which slipped 31 cents to $80.18.
The premium of Brent over U.S. benchmark West Texas Intermediate (WTI) ballooned overnight after industry group the American Petroleum Institute (API) said on Tuesday that crude stockpiles at Cushing rose to a new record high of more than 37 million barrels last week.

The discount of the front-month WTI contract to the second month also widened sharply overnight to reach about $4 a barrel.
ROLLER COASTER CRUDE
Oil prices have been volatile since the European Union announced a rescue package for the bloc's debt-stricken nations totaling almost $1 trillion two days ago. On Wednesday, prices were less than $2 from a 12-week low reached on Friday, before weekend talks succeeded in setting up the emergency fund.
"The market first reacted with short-covering on the news, but then we found that the problem is still there," Sano said.
"It is still not so optimistic about the EU economy even after the huge commitment. I'm bullish in the middle term still, but short-term circumstances are really bad."
The U.S. Energy Information Administration (EIA) raised its 2010 world oil demand growth forecast from its previous estimate in a monthly short-term energy outlook published on Tuesday, when OPEC raised its own estimate for a third consecutive month. [
] [ ]U.S. crude had touched $87.15 on May 3, its highest level in almost 19 months, on optimism that the global economic recovery would boost demand after two straight years of declines.
The API said crude stocks rose by a less-than-expected 362,000 barrels in the week to May 7, while gasoline stocks posted a surprise drop of 906,000 barrels. Distillates, which include heating oil and diesel fuel, edged up 94,000 barrels.
But stocks at Cushing gained 783,000 barrels. [
]"Cushing stock is increasing and will continue to increase for another two months until the refinery utilisation rates come back," Sano said.
Government data on U.S. inventories from the EIA follows at 1430 GMT on Wednesday. The report is expected to show a 1.3-million-barrel increase in crude supplies, a gain of the same size for distillates and an addition of 700,000 barrels for gasoline. [
]The dollar gained about 0.3 percent against a basket of currencies on Wednesday, contributing to oil's drop because a stronger U.S. currency renders crude imports more expensive for developing nations where demand is soaring. (Editing by Ed Lane)
