Oil prices fell on Tuesday on anticipation of another weekly build in U.S. crude stockpiles.

Position squaring ahead of the expiry of the front-month contract in U.S. crude also accounted for a large part of activity, traders and analysts said.

"The bears seem to be having an edge this week after the strong gains of the past week," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.

U.S. crude for May, which expired at the close of Tuesday's session, closed down $1.12, or 1.99 percent, at $55.26 a barrel. U.K. North Sea , the more widely used benchmark for oil slipped $1.30, or 2 percent, to $62 a barrel.

A preliminary Reuters survey on Monday showed that U.S. crude inventories likely rose by 2.4 million barrels last week, for a 15th straight week of builds.

The American Petroleum Institute, an industry group, will issue its own reading on the inventory situation at 4:30 p.m. EDT, before official stockpile data due from the government on Wednesday.

Traders said Brent was pressured by the global oversupply in oil, including U.S. crude, even as worries about a civil war in Yemen provided some support.

Despite Tuesday's declines, both Brent and U.S. crude remained up more than 15 percent for April after gains over the past two weeks on speculation that the selloff in oil that began last summer is losing steam.

Some analysts disagree that the market is on the cusp of a longer-term recovery.
