(Updates market action)

NEW YORK, Jan 30 (Reuters) - Wall Street stocks and gold surged and Treasuries fell on Wednesday as worries over slow economic growth eased and inflation fears mounted following the second U.S. Federal Reserve interest rate cut in eight days.
The dollar fell sharply to two-week lows, and key commodities bounced from early declines. Gold hit a record at above $940.
The Fed cut its key rates by half a percentage point at the end of its two-day policy meeting. Before the decision, traders were evenly split over whether the central bank would cut rates by half a point or a quarter point.
"This move is really designed to help financial markets, even if it allows inflation pressures to pick up later on down the line," said Amo Sahota, president and head trader of Global Research,HiFX.
In trading an hour after the cut, the Dow Jones industrial average <
> was up 185 points, or 1.5 percent, at 12,666. The Standard & Poor's 500 Index <.SPX> was up 22 points, or 1.64 percent, at 1,386. The Nasdaq Composite Index < > was up 35 points, or 1.5 percent, at 2,393.Treasury bond investors were more worried about the chance for inflation down the road than equities traders, whose recession fears have restrained stocks this year. Benchmark 10-year notes <US10YT=RR> were last down 13/32 on the day, which pushed yields up to 3.73 percent.
"The Treasury market's reaction tells you the long end of the market, contrary to what the Fed says, is really worried about inflation," said John Derrick, director of research and fixed-income securities manager at U.S. Global Investors Inc of San Antonio, Texas. "This is very aggressive action of 125 basis points of cuts in about a week."
The Fed set up expectations of an aggressive move after it made a 3/4-point rate cut in an emergency action last week. Skepticism grew over another sharp cut on scattered signs of U.S. economic recovery and concern that the Fed's emergency measure may have been a flawed response to short-term market declines sparked by a rogue trader at French bank Societe Generale <SOGN,PA.>.
Rate cut hopes rose again early on Wednesday, though, on a report that U.S. economic growth last year dropped to a five-year low of 2.2 percent, with a fourth-quarter gain of just 0.6 percent, half the expected rate.
Earlier, European stocks and the dollar were hit as UBS <UBSN.VX> unveiled $4 billion in new write-downs, stirring fears of a deepening credit crisis. UBS was among the hardest-hit of the banks around the world that have collectively suffered more than $100 billion in losses from the crisis originating from defaults in U.S. subprime mortgages.
The big Swiss bank's charges reminded investors that the Fed action can do nothing to help results in the earnings season starting on Wall Street.
"The fourth-quarter reporting season will be a real acid test for the banks," said Franz Wenzel, strategist at AXA Investment Managers in Paris. "Most of the banks will try to put all the write-downs in their 2007 results as they want to clean the balance sheet going forward."
Some investors were betting that the bottom has already been reached in a U.S. recession that probably began last year. The view gained support early in the day as private data provider ADP reported 130,000 new U.S. private-sector jobs were created in January, three times the consensus forecast.
Investors were less concerned over the impact of higher prices, which the Fed must worry about as it stimulates the economy. Commodities drifted lower on the surprising decline in fourth-quarter GDP growth.
"The Fed understands that it needs to make hay while the sun shines by pumping as much liquidity into the economy now, while it still can, before the public's inflation expectations catch up with reality," said John Kosar, president of Asbury Research in Chicago.
