NEW YORK, June 18 (Reuters) - A bearish outlook from U.S. parcel delivery service FedEx Corp and revived worries about banks sent U.S. and European stocks sharply lower on Wednesday while U.S. government bonds extended a two-day rally on a renewed bid for safety.
Oil rebounded from earlier declines as a strike threat by workers in OPEC nation Nigeria stoked supply concerns and the White House said it did not expect Saudi Arabia to announce an output increase during a meeting on Sunday in the kingdom. Other farm commodities rallied again as the Midwest farm belt flooding spread its destruction through crop lands.
Financial stocks in the United States and Europe took a fresh battering after U.S. banks Morgan Stanley <MS.N> and Fifth Third <FITB.O> disclosed credit-related struggles.
An announcement by regional banker Fifth Third that it needs $2 billion to cope with credit losses heightened concerns aroused on Tuesday when an analysts at Goldman Sachs & Co said U.S. banks may need to raise $65 billion in fresh capital.
Fifth Third <FITB.O> stock closed down 27 percent.
At session lows, the Dow Jones industrial average hit its lowest level since mid-March immediately after the Federal Reserve's rescue of Bear Stearns.
The Dow Jones industrial average <
> closed down 131.24 points, or 1.08 percent, at 12,029.06, after recovering from just a fraction below 12,000. The Standard & Poor's 500 Index <.SPX> fell 13.09 points, or 0.97 percent, at 1,337.84. The Nasdaq Composite Index < > was off 28.02 points, or 1.14 percent, at 2,429.71."What's coming to light is the process the regional banks now have to go through in terms of raising capital," said Owen Fitzpatrick, head of the U.S. Equity Group at Deutsche Bank Private Wealth Management in New York.
"You're not going to see the same level of interest from private equity, hedge funds and the sovereign wealth funds like you saw for the money-center banks," he said.
The KBW index of large U.S. financial shares slipped 2.9 percent, with almost all 24 components down.
Morgan Stanley's <MS.N> shares fell sharply after it said trading losses and a slowdown in investment banking hurt its results. The bank's shares later pared most of their losses.
Adding to the gloom was FedEx, a closely watched barometer of U.S. business activity because it ships goods for a vast number of businesses. The company posted a quarterly loss and forecast a dismal fiscal 2009 due to high fuel prices and a weak U.S. economy.
"The autos, financials and transport sectors are very sensitive to the perception is that economic growth is waning," said Bruce Zaro, chief technical strategist at Delta Global Advisors in Boston. "We've had little evidence the economy is at (its) bottom."
Banks also led the decline in Europe, with Royal Bank of Scotland <RBS.L> off 5 percent, UBS <UBSN.VX> down 4 percent and Santander <SAN.MC> dropping 2.3 percent.
In the energy sector, BP <BP.L> fell 2.1 percent as oil prices fell, making it the largest individual drag on the broader market.
The pan-European FTSEurofirst index <
> ended down 1.4 percent at 1,251.00. Earlier the index hit a session low of 1,246.62, its lowest level since the end of March."The market clearly is very strongly in the clutches of the bear, there's no question about it," said Mike Lenhoff, chief strategist at Brewin Dolphin.
"At the moment it looks pretty bleak," he said.
U.S. Treasuries debt prices rose as widening stock market losses enhanced the bid for safe-haven government debt and made a Federal Reserve rate hike this summer look less likely.
"The perception is that the Fed can't raise rates the way the market was thinking they were going to do, mainly because of problems with some very notable regional banks which are trading at their 52-week lows," said Thomas di Galoma, head of U.S. Treasuries at Jefferies & Co in New York.
"The Fed doesn't want to cause any further problems by raising rates," he said.
The benchmark 10-year U.S. Treasury note <US10YT=RR> rose 15/32 to yield 4.1403 percent. The 30-year U.S. Treasury bond <US30YT=RR> added 24/32 to yield 4.71 percent.
The dollar edged lower as investors reviewed their interest rate outlooks for the United States and the euro zone after slack economic data this week and a fresh bid by monetary authorities to tone down the threat of tighter policy.
The dollar fell against major currencies, with the U.S. Dollar Index <.DXY> down 0.13 percent at 73.42. Against the yen, the dollar <JPY=> fell 0.09 percent at 107.81.
