Oil traded as high as $100 a barrel last week as tensions in the Middle East heated up. Investors worried that political complications could cause a pullback in supplies.
But oil prices fell more than 4% Wednesday, to close at $91.98 a barrel -- hitting levels not seen since early August. And Brent crude, Europe's benchmark, also slid nearly 4%.
"The very sharp pullback in oil comes as nearly every economy is running at stall speed," said Stephen Schork, editor of oil newsletter Schork Report. "Demand for oil is certainly questionable, and we're feeling more comfortable with worldwide supplies."
To that end, the Saudi Arabian government has promised to increase supply if needed, according to news reports. The Saudi promise, said Schork, has made traders quickly forget last week's worries and concentrate instead on demand. And the latest U.S. government report showed a greater buildup in crude inventories than expected.
Housing stocks moved higher after the existing home sales report. Shares of home improvement retailers like Home Depot (Fortune 500) and , Lowe's (Fortune 500), as well as home builders , PulteGroup (, )Lennar ( and )KB Home ( gained between 1% and 4%. )
Overall, investors appear to be fearful of doing much of anything in stocks as they try to get a handle on where the economy is headed. Wednesday's mixed housing reports did little to inspire widespread confidence in a sustained recovery.
Before the U.S. markets opened, the Bank of Japan said it would expand its asset purchase program by ¥10 trillion to about ¥80 trillion to boost its slowing economy.
Central bankers around the world have been stepping up their stimulus plans to help fuel the global economy. Just last week, the Federal Reserve said it would buy $40 billion worth of mortgage backed securities a month. That came after the European Central Bank revealed its new bond-buying program.
All of those moves have pushed up the euro to a five-month high against the U.S. dollar. The yen initially rallied on the back of Japan's central bank announcement. And gold prices, used as a hedge against inflation, soared to a nearly seven-month high on the BoJ announcement, before pulling back after the housing report.
European stocks also initially popped on the BoJ news, but ongoing worries about Europe's debt crisis muted the enthusiasm. Britain's FTSE 100, France's CAC 40 and the DAX in Germany closed up between 0.4% and 0.6%.
