West Texas Intermediate crude fell the most in two months, widening its discount to Brent to more than $10 a barrel, as U.S. supplies surged. The government announced a test sale of Strategic Petroleum Reserve oil.
WTI settled below $100 for the first time since Feb. 11. Crude stockpiles rose 6.18 million barrels last week, the Energy Information Administration said, more than triple the 2 million median estimate of analysts surveyed by Bloomberg. The Obama administration said it plans to offer 5 million barrels of sour crude from the reserve in a test of the distribution system.
“The overall gain in crude stocks is pretty negative,” said Bill O’Grady, chief market strategist at Confluence Investment Management in St. Louis, which oversees $1.4 billion. “That’s a huge build. Crude will probably go down to $95 and find a bottom there.”
WTI for April delivery declined $2.04, or 2 percent, to $97.99 a barrel on the New York Mercantile Exchange, the lowest settlement since Feb. 6. The one-day drop is the biggest since Jan. 2.

Prices have tumbled 6.6 percent since closing at a five-month high of $104.92 on March 3.
“The bigger-than-expected build certainly adds to the bearish thesis,” said Rich Ilczyszyn, chief market strategist and founder of Iitrader.com in Chicago. “The market was way overdone at $104.”
Crude inventories rose as domestic production climbed 1.3 percent to 8.18 million barrels a day, the most since July 1988. Refinery operations slipped 1.4 percentage point to 86 percent of capacity, the least since October.
Gasoline stockpiles shrank to 223.8 million barrels last week, the lowest level this year. Distillate fuel, including diesel and heating oil, decreased 533,000 barrels to 113.9 million. Analysts had expected a decline of 450,000 in distillate. Gasoline supplies slid 5.23 million barrels. They were forecast to fall 2 million.
“The overall demand is strong and it poses a reason to be bullish,” said Carl Larry, president of Oil Outlooks & Opinions LLC in Houston.

The offers are due on March 14. The reserve held 695.9 million barrels of crude last year, according to the department’s website.

OPEC production is in line with its current collective target of 30 million.
