NEW YORK, April 25 (Reuters) - U.S. crude rose on Wednesday, shrugging off data showing rising domestic fuel inventories and production, and both U.S. crude and Brent held within sight of three-year highs reached the previous day.
Supplier cutbacks, steady demand growth, geopolitical tensions and a favorable structure in the futures market have attracted record investment in oil this year.
A rise in U.S. government borrowing costs to their highest since 2013 this week has tempered some investor appetite for risk, but analysts said Brent crude futures, the global benchmark, may yet rise toward new 2018 peaks above $75 a barrel.
Brent was down just 26 cents at $73.60 by 10:55 EDT (1555 GMT), just 2 percent below the November 2014 high of $75.47 reached on Tuesday. U.S. crude futures were up 1 cent at $67.71 a barrel.
Prices briefly tested session lows after U.S. government data showed U.S. crude and gasoline stockpiles rose unexpectedly last week.
Crude inventories rose 2.2 million barrels in the week to April 20, compared with expectations for a decrease of 2 million barrels. Crude stocks at the Cushing, Oklahoma, delivery hub rose 459,000 barrels, EIA said.
“The market is being led down by gasoline as inventories rose due to an extraordinary high level of imports and that is weighing on crude oil prices,” said Andrew Lipow, president of Lipow Oil Associates in Houston. “Tempering some of that weakness is the record exports of crude oil and distillate fuel last week.”
Geopolitical tensions including the prospect of fresh sanctions on Iran and disruption to the country’s oil flows helped push oil higher this month.
Money managers hold record positions in Brent crude futures and options, lured by the hefty premium of the front-month June contract over subsequent months that makes it profitable to invest in crude over the longer term.
“The prospect of a downside correction in prices is lost on the speculative fraternity. In fact, financial players have rarely felt more optimistic. Bets on rising crude prices are close to a near-record high,” PVM Oil Associates strategist Stephen Brennock said.
“However, given the already vast holdings of long positions in oil, there are doubts over the scope for further inflows.”
The forward curve for Brent is now above $70 until the end of 2018, and prices are above $60 through 2020.
But the rise in U.S. Treasury yields above 3 percent has driven the dollar to three-month highs, making oil more expensive for buyers using other currencies. This might eventually pressure crude prices, even though oil and the dollar have moved in tandem for a few weeks.
