NEW YORK, Jan 12 (Reuters) - Commodity prices slid and stocks slumped around the world on Tuesday after China said it would raise banks' reserve requirements in a move that could damp a recovery from the worst global recession in decades.
A weak start to the corporate earnings season in the United States and a profit warning from Chevron Corp <CVX.N> also hurt investor sentiment.
European equities retreated from a 15-month high to close lower while U.S. stocks fell, snapping a six-day winning streak, after aluminum maker Alcoa Inc <AA.N>, the first major U.S. company to release earnings, reported weaker-than-expected results.
Asian stocks also fell, a day after hitting a 17-month high, on investor jitters that tighter Chinese monetary policy could slow economic expansion in China and cut the country's strong worldwide demand for commodities and other goods.
The People's Bank of China surprised markets with a statement that next week it would raise the reserve requirement ratio in a move to stem the threat of inflation. For details see: [
]."China may be trying to limit its growth rate," said Gene McGillian of Tradition Energy in Stamford, Connecticut.
"Asian oil demand has been growing fast, but we haven't really seen demand growth kick in in the United States or Europe."
Oil fell by more than 2 percent from near a 15-month high, helped by the easing of cold weather in the United States that had been supporting U.S. fuel demand. [
]The sudden central bank move in China came earlier than investors had expected and appeared prompted by concerns that a renewed surge in bank lending was flooding the economy with cash, risking overheating and a surge in inflation.
Concerns in the United States that banks and other financial services firms could face government fees in a bid to recoup losses tied to industry bailouts sent the Nasdaq and S&P 500 stock indexes down by about 1 percent.
A senior U.S. official confirmed President Barack Obama is considering a levy as part of the fiscal 2011 budget he will unveil in February. Media reports said the fee could raise as much as $120 billion.
