New York (Reuters) - Oil prices were little changed on Wednesday after an increase in U.S. crude stockpiles and demand worries stemming from gloomy economic prospects in Europe offset concerns about conflict in the Middle East escalating.
Brent futures fell $0.29 to $87.78 a barrel at 11:10 a.m (1510 GMT). U.S. West Texas Intermediate (WTI) crude fell $0.59, or 1%, to $83.15.
Weaker prices in the oil physical markets suggest the rise in prices over the past few weeks may come to an end as demand woes weigh.
U.S. crude inventories rose by 1.4 million barrels in the last week to 421.1 million barrels, the Energy Information Administration reported on Wednesday, higher than analysts' expectations in a Reuters poll.
"It's more bearish because you have a big switch from a big draw in the API data to a build in the EIA data," said Bob Yawger, director of energy futures at Mizuho. "Refinery utilization was still down which means turnaround season is not over."
U.S. inventories declined unexpectedly by about 2.7 million barrels in the week ended on Oct. 20, according to market sources citing American Petroleum Institute figures on Tuesday.[API/S]
"The crude build is a bit of a surprise and gasoline demand is barely hanging in there," said John Kilduff, a partner at Again Capital LLC, in New York.
"The European economic numbers haven't been good, which could be affecting demand," he added.
In Europe, growth indicators from industrial output data to purchasing managers' surveys and sentiment readings in recent weeks are all suggesting that the euro zone's economy is now either stagnating or even shrinking as weak external demand, consumer caution and high interest rates take their toll.
Bank lending across the euro zone came to a near standstill last month, European Central Bank data showed on Wednesday, providing further evidence that the 20-nation bloc was skirting a recession.
Meanwhile, Israel intensified its overnight bombing of southern Gaza, where officials said record numbers of Palestinians had been killed again, as violence flared elsewhere in the region and a showdown loomed at the United Nations on Wednesday over desperately needed aid.
If the conflict widens across the Middle East, oil supplies could be disrupted in a market already undersupplied given protracted OPEC+ cuts.
Crude prices could also find support as the top parliament body in China, the world's biggest oil importer, approved a bill to issue 1 trillion yuan ($137 billion) in sovereign bonds and allow local governments to issue new debt from their 2024 quota to boost the economy.
But demand for crude oil in China could be limited as Beijing put a ceiling for its oil refining capacity at 1 billion metric tons by 2025 to streamline its vast oil processing sector and curb carbon emissions.
