NEW YORK, May 13 (Reuters) - Oil prices fell on Thursday on high U.S. inventories and concerns about the economic recovery, while short-covering in the front month narrowed U.S. crude spreads from their widest levels in 15 months.
Front-month U.S. crude <CLc1> for June delivery dipped 27 cents to $75.38 a barrel, at 12:50 p.m. EDT (1650 GMT), having hit $73.62, the lowest since Feb. 12.
June's discount to July U.S. crude<CLN0>, had widened in early trading due to rising inventories at the Cushing, Oklahoma delivery point for the New York Mercantile Exchange's oil futures contract. The spread widened to nearly $5 in early activity -- its highest level since February 2009. <CL-1=R> -- but then it narrowed as short-covering lifted the front month.
"After that further widening of U.S. July crude's premium over July, we've seen some short-covering, and that helped pare some of June's losses," said Tom Knight, trader at Truman Arnold, in Texarkana, Texas.
London Brent <LCOc1> traded down 91 cents to $80.29 a barrel, narrowing its premium to U.S. oil by $1.64 to $4.91 a barrel after topping $6, the highest in 15 months.
Rising global energy demand and hopes Europe can get its debt crisis under control have supported Brent rise for three of the last four days. U.S. crude prices have fallen for seven of the last eight sessions. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Industry data provider Genscape said crude at the Cushing, Oklahoma, hub rose by 1.2 million barrels to a record 38.96 million barels in the week to May 11, the seventh straight week of gains. [
]The record build has pulled down front month U.S. crude in recent weeks. Analysts say Cushing's landlocked location means it tends to reflect supply and demand in the midwestern United States, while Brent prices more accurately reflect oil's value to wider markets.
"In general, Brent is acting as a much better benchmark for global fundamentals at the moment," Barclays Capital analyst Amrita Sen said.
The latest U.S. economic data failed to quell worries about the pace of the recovery.
New unemployment benefit claims fell slightly less than expected but that the number of people still drawing benefits rose unexpectedly. [
]Crude prices were further pressured by a drop in equity markets due to the lackluster report on jobless claims and concerns about austerity measures in Europe. [
] [ ] [ ]U.S. gasoline inventories unexpectedly dropped by 2.8 million barrels last week, the Energy Information Administration said on Wednesday. Total U.S. crude inventories were up by 1.9 million barrels, much more than analysts expected. [
]The euro slipped close to its lowest level in 14 months against the dollar, on worrires that harsh fiscal tightening in Europe would lead to slower growth. [
]That weighed on commodities priced in dollars as investors placed safe-haven bets on the greenback.
The euro zone debt crisis roiled energy markets last week, knocking U.S. crude from a 19-month peak of $87.15 on May 3. (Additional reporting by Robert Gibbons in New York, David Sheppard in London, Alejandro Barbajosa in Singapore; Editing by David Gregorio)
