NEW YORK (Reuters) - Oil dropped more than $6 on Tuesday, the largest drop in dollar terms in 17 years, as growing concern about the economic health of top energy consumer the United States stirred demand worries.
U.S. Federal Reserve Chairman Ben Bernanke said financial markets were under “considerable stress,” adding to concerns about the strain of the weak housing market and high energy and food prices on the U.S. economy.
U.S. crude settled down $6.44 at $138.74 a barrel, the biggest one-day drop since 1991, when prices retreated at the start of Operation Desert Storm. The session low was notched at $135.92 earlier.
London Brent crude fell $5.17 to $138.75.

Investors have piled into oil and other commodities this year as a hedge against inflation and the weak dollar, pushing crude up nearly 50 percent to over $147 a barrel this month.

“For the oil markets, that weighs heavily on demand. As the U.S. economy continues to struggle, demand for oil going forward is worrisome. On gasoline, for example, demand has contracted already and refinery margins are going down.”
