West Texas Intermediate slipped from near a five-week high amid rising crude inventories in the U.S., the world's biggest consumer of the commodity. Futures fell as much as 0.5 percent. Crude stockpiles advanced 3.7 million barrels last week, the American Petroleum Institute said yesterday. The euro fell to its weakest level since Nov. 21 against the dollar, undermining the appeal of commodities priced in the U.S. currency. An Energy Department report today may show a gain of 1.3 million, according to a Bloomberg News survey. WTI rose 1.6 percent yesterday, the most this year, as U.S. durable goods orders and home prices climbed more than economists forecast. "The crude inventory builds reported last night are weighing on prices," said Robert Montefusco, a senior broker at Sucden Financial Ltd. in London, who earlier this month correctly predicted oil prices would decline. "The euro is getting bashed as Europe's situation looks dire, which is also pressuring oil." WTI for May delivery dropped as much as 49 cents to $95.85 a barrel in electronic trading on the New York Mercantile Exchange, trading for $95.91 at 9:37 a.m. London time. The volume of all futures traded was 46 percent below the 100-day average.
