* Oil surges to near $134 barrel, raising inflation fears
* Federal Reserve slashes 2008 economic growth forecast
* Stocks tumble; gold and euro hit one-month peaks

NEW YORK, May 21 (Reuters) - Global stocks tumbled on Wednesday as a U.S. Federal Reserve outlook for possible higher inflation and a weaker economy hit investors already fretting over oil's record surge.
Crude rose almost $5 a barrel to its third straight record futures market high after a U.S. government report showed a surprise drop in crude stockpiles, rekindling fears of a supply crunch.
The rapid rise in crude oil, up 33 percent so far this year, stoked fears of global inflation and sagging economic growth. The new surge in energy prices has undermined equity markets that have recently been erasing their 2008 losses.
The Fed signaled in minutes from a policy-makers' meeting in April that it was unlikely to cut interest rates further. The comments led U.S. Treasury debt prices to pare losses and pushed U.S. stocks indices, already trading down on surging oil and inflation fears, lower still late in the session.
The dollar fell to a one-month low against the euro and touched a one-week trough versus the yen . Earlier, a bullish economic outlook for Germany helped lift the euro.
The market's concerns over rising oil were reflected in company disclosures on energy-related issues. The chief executive of aircraft maker Boeing said he was concerned record crude prices are crimping the growth of his major airline customers.
Shares of Boeing fell 4.86 percent to $81 and were the biggest drag on the Dow industrials. The comments came hours after AMR Corp's American Airlines announced it would slash domestic capacity in the face of soaring fuel prices.
An index of airline stocks <.XAL> slid 12 percent and retailers, home builders and financial services stocks also lost ground.
Oil stocks climbed to 52-week highs.
"The market is starting to decide that at some point higher oil is going to be an economic drag. Given the fact that inflation ripples through the economy slowly the market is right to have that concern," said Chip Hanlon, president of Delta Global Advisors, Inc, in Huntington Beach, California.
The rising prices for materials have stoked fears of broader inflation and posed problems for central banks under pressure to cut interest rates to stimulate slowing economies.
The third straight record high in oil pulled other key commodities higher. Gold hit one-month highs, and corn and soy rose in Chicago commodity markets.
The Reuters-Jefferies CRB Index <.CRB> of 19 commodity futures closed up 1.7 percent to a new record high of 434.40.
The Dow Jones industrial average <
> fell 227.49 points, or 1.77 percent, at 12,601.19. The Standard & Poor's 500 Index <.SPX> was down 22.69 points, or 1.61 percent, at 1,390.71. The Nasdaq Composite Index < > was down 43.99 points, or 1.77 percent, at 2,448.27. Wall Street:U.S. crude <CLc1> settled up $4.19 at $133.17 a barrel after hitting a fresh peak of $133.72. London Brent <LCOc1> rose $5.21 to $133.05.
"The higher oil price is going to affect the consumer. It affects the psychology much like lower stock prices affect the wealth effect," said Alan Lancz, president of investment advisory firm Alan B. Lancz & Associates Inc in Toledo, Ohio. "Something has got to give. If it's not oil, it's going to be stock prices."
European stocks extended the previous day's sharp losses as the spike in crude oil heightened inflation fears and clouded the outlook for corporate profits.
Oil stocks such as BP <BP.L> and Royal Dutch Shell <RDSa.L> helped cushion the market's fall. BP gained 3.2 percent, while Royal Dutch Shell surged 4.5 percent.
The FTSEurofirst 300 <
> index of top European shares closed 0.7 percent lower at 1,340.63 points, its lowest close since May 1.U.S. gold futures ended just below $930 an ounce as a sharp rally of crude oil prices stirred inflation fears. Gold's role as an inflation hedge rose on the surge in crude prices.
The New York gold contract for June delivery settled up $8.40 at $928.60 an ounce, soaring earlier to $933, the highest level since April 22.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 9/32 to yield 3.81 percent. The 2-year U.S. Treasury note <US2YT=RR> fell 6/32 to yield 2.40 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 6/32 to yield 4.55 percent.
