NEW YORK, March 24 (Reuters) - Oil fell more than $1 a barrel on Wednesday, weighed down by data showing a larger-than-expected rise in crude stocks and a stronger U.S. dollar.
U.S. crude oil futures for May <CLc1> fell $1.20 to $80.71 a barrel by 1:43 p.m. EDT (1743 GMT).
The contract touched a session low of $79.88 a barrel as the market reacted to the higher-than-expected crude inventory jump, but positive gasoline demand figures helped stem the price decline.
Crude futures have traded between $69 and $84 so far this year.
London ICE Brent <LCOc1> for May slipped $1.03 to $79.67 after earlier dipping to a low of $78.90.
U.S. crude stockpiles jumped 7.3 million barrels in the week ended March 19, the U.S. Energy Information Administration (EIA) said, broadly confirming a 7.5 million barrel build reported by the American Petroleum Institute (API) on Tuesday. <API/S> <EIA/S>
"The EIA data essentially mirrors that of API, with gasoline being the exception. Larger-than-expected builds in crude oil reduced prices, not to ashes, but to $80," said Jay Levine of enerjay LLC, based in Portland, Maine.
Brad Samples at Summit Energy said the build mostly came from imports and refineries could process more oil as the U.S. driving season got underway.
"The big build all comes from imports, which rose to their highest level since September, 2009," he said.
"Refinery utilization rates have been rising along with import levels, and the rise will probably continue as we head toward the (U.S.) driving season. We've been eating away at gasoline stocks," he added.
The EIA said gasoline stocks fell 2.7 million barrels, more than the 1.3 million forecast in a Reuters poll of analysts.
AT HOME IN THE RANGE?
Some analysts said the market was watching the dollar and European economies and was unable to take a fundamental spur to break out of current ranges.
"The market is so entrenched in this trading range -- $77.50 on the downside and $83.50 on the upside -- that no one is really interested in taking a position either way. Traders have their minds on other markets such as the U.S. dollar and the whole European quagmire," Mike Zarembski at Optionsxpress in Chicago said.
The dollar rose against the euro after Fitch Ratings cut Portugal's sovereign credit rating one notch to AA-, putting further pressure on the single currency. [
