New York's main contract, light sweet crude for September delivery, gained 40 cents to $95.29 a barrel.

Brent North Sea crude for delivery in September rose 16 cents to $116.97.

Crude markets were resting after volatile trade on Tuesday, said Serene Lim, oil and gas analyst for ANZ bank in Singapore.

"I think it's trading very sideways today after very choppy trading last night... markets are taking a pause," she told AFP.

Crude prices had leaped in early Monday trade following US President Barack Obama's announcement of an 11th-hour deal to avert a potentially devastating debt default in the world's largest oil consumer.

But they went back into the red after data showed the US manufacturing sector contracting in July, highlighting increased and deep-seated concerns about Washington's economy, analysts said.

The Republican-led House voted late Monday to approve the Obama-backed package to raise the limit on US borrowing and enact at least $2.1 trillion in spending cuts over the next decade.

The Democratic-led Senate was expected to approve the emergency measure in a noon (1600 GMT) vote Tuesday -- scarcely 12 hours before a midnight deadline by which the world's richest nation would run out of cash to pay its bills.
