NEW YORK, Oct 21 (Reuters) - Fears of a global recession drove stock and commodity markets lower on Tuesday despite a further thawing in credit markets and more steps by authorities around the world to bolster investor confidence.
Downbeat outlooks from some key U.S. companies helped revive a bid for safety, lifting the price of U.S. government debt and spurring the U.S. dollar to a one-and-a-half-year peak against a basket of major currencies.
Gold futures dropped as much as 4 percent as the dollar's rally and relatively calm global markets dimmed the metal's appeal as an alternative investment.
A sharp pullback in commodity prices and commodity-linked stocks on global growth concerns and a potential worldwide recession sent a pall over financial markets, despite renewed efforts to loosen still-tight credit.
"It's a foregone conclusion that the economy is slowing and that companies are going to be issuing downbeat forecasts," said Richard Sparks, senior equities analyst at Schaeffer's Investment Research in Cincinnati, Ohio.
The Dow industrials fell 2.5 percent, while the Nasdaq skidded over 4 percent, outpacing losses in European markets.
Japan and France extended more help to banks, the International Monetary Fund prepared to intervene in trouble spots around the world, and the U.S. Federal Reserve devised a new plan to inject liquidity into troubled money markets.
Interbank lending costs fell further, offering tentative signs of renewed confidence in a battered global banking system. Weeks of bailouts and rescue plans appear to have cooled the worst financial crisis since the Great Depression.
Commodity prices pointed to recession worries. Oil fell 4.5 percent to under $71 a barrel and copper slipped to lows last seen in January 2006 after China, the largest consumer of industrial metals, saw growth slow in the third quarter.
Both copper and oil are trading more than 50 percent lower than the peaks they reached in July.
"The deleveraging story will continue and remain in place for quite some time," said Audrey Childe-Freeman, a currency analyst at Brown Brothers Harriman in London. She referred to the sale of distressed assets to cut debt or cover losses.
U.S. stocks skidded as companies cut their earnings outlooks. Automotive stocks pulled European shares lower in another sign of falling demand, and energy shares on both sides of the Atlantic tracked the fall in crude prices.
