NEW YORK - Oil prices fell sharply Thursday after the Energy Department reported unexpected declines in crude oil supplies last week but said the drop was caused by temporary delays in unloading tankers along the Gulf Coast.
The decline of $4.41 a barrel came as a stronger dollar and concerns about gasoline demand also weighed on prices.
Retail gasoline prices, meanwhile, rose to a new record above $3.95 a gallon.
Light, sweet crude for July delivery settled at $126.62 a barrel on the New York Mercantile Exchange. It was the lowest settlement in two weeks and the biggest single-day price drop since March 19.
In Washington, meanwhile, the Commodity Futures Trading Commission revealed that it is six months into a wide-ranging investigation of U.S. oil markets, with a focus on possible price manipulation.
The commission also announced a handful of initiatives designed to increase transparency of the energy futures markets.
The commission said it started the investigation in December and was publicizing it "because of today's unprecedented market conditions."
Disclosure of the investigation may have contributed to oil's declines, analysts said.
