NEW YORK, Aug 19 (Reuters) - Global stocks fell sharply and oil prices shot higher from dollar weakness on Tuesday as credit concerns again rattled investors and a spike in U.S. wholesale prices reignited concerns about future inflation.
Crude oil, which had traded earlier in the day below $112 a barrel, surged to around $116 after the dollar slipped and traders squared positions by selling before contracts expire Wednesday.
The dollar initially gained on the view that the Federal Reserve will be forced to raise interest rates to curb the pace of inflation. A government report showed U.S. producer prices jumped at the fastest rate in 27 years in July.
But traders took advantage of the steep slide in stocks to book profits on the dollar's recent gains. The euro was on pace to post its best one-day gain in a month, while a dollar index was on track for its worst daily loss in about five weeks.
U.S. Treasury and euro zone debt prices also initially gained in safe-haven buying, taking their cue from stocks.
European shares dropped in a broad sell-off to their lowest close in two weeks on renewed credit fears and U.S. data that showed U.S. economic woes are far from over.
The threat of sharply higher inflation and renewed worries that the two leading U.S. mortgage finance companies could face steep losses weighed heavily on Wall Street.
Data pointing to the slowest pace of housing starts in more than 17 years highlighted the deterioration in U.S. housing.
A forecast by JPMorgan Securities that investment bank Lehman Brothers <LEH.N> will likely take a further $4 billion of write-downs in the third quarter due to losses from mortgage-related investments also fanned investor gloom.
Lehman shares fell more than 10 percent as the S&P financial index <.GSPF> declined 3.5 percent.
"We are back to struggling again in the financial sector particularly," said William Stone, chief investment strategist at PNC Financial in Philadelphia. "Underneath some of that is just concern about the overall global economic slowdown."
Before 1 p.m., the Dow Jones industrial average <

The Nasdaq Composite Index < > was down 26.53 points, or 1.10 percent, at 2,390.45. Wall Street:Banks also took a beating in Europe amid continued fallout from a Barron's report over the weekend that suggested the U.S. government may need to nationalize mortgage finance giants Freddie Mac <FRE.N> and Fannie Mae <FNM.N>.
Royal Bank of Scotland <RBS.L> sank 5.9 percent, Fortis <FOR.BR> tumbled 5 percent and Commerzbank <CBKG.DE> shed 4.9 percent. The DJ Stoxx bank index <.SX7P> fell 4.3 percent.
The FTSEurofirst 300 <
> index of top European shares closed 2.5 percent lower at 1,159.39 points.While the bond and currency markets focused on the U.S. wholesale inflation data, some on the equity markets said the U.S. housing data was of greater concern.
"Inflation will continue to be a concern, but the real worry is still in the housing market," said Franz Wenzel, strategist at AXA Investment Managers in Paris.
"We will continue to have bleak data for a while. We know from the Japanese example that a housing slump usually lasts for longer than economists can think of."
Longer-dated U.S. Treasury debt prices eased after relatively strong demand from a sale of Freddie Mac debt cut into the safe-haven bidding for government bonds.
The $3 billion of debt sold by Freddie alleviated some concerns that it and sibling Fannie might have trouble accessing capital outside of any emergency government backing.
Euro zone government bond futures also turned negative in late in the session, having earlier climbed to a fresh three-month peak, as momentum fizzled in thin trade.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 5/32 to yield 3.84 percent. The 30-year U.S. Treasury bond<US30YT=RR> fell 12/32 to yield 4.46 percent.
While the dollar fell, gold and other commodities also pushed higher.
"On crude, trendline support is holding and the dollar is exhausted and falling," said Mark Waggoner, president of Excel Futures in Huntington Beach, California.
The dollar fell against major currencies, with the U.S. Dollar Index <.DXY> down 0.46 percent at 76.747. Against the yen, the dollar <JPY=> was down 0.29 percent at 109.76.
