* Bonds get boost in thin volume on safe-haven buying

NEW YORK, June 23 (Reuters) - Oil bounced above $137 a barrel on Monday and lifted energy shares but compounded fears in the U.S. and European equity markets of slowing growth, inflation and the credit-stressed financial sector.
The dollar moved higher ahead of a Federal Reserve meeting this week that investors expect to involve stern talk about the risks of rising inflation.
It gained against the euro as signs of growing economic weakness in the euro zone. Data showed manufacturing and service sectors contracted in May and German business sentiment fell.
U.S. Treasury debt prices were steady to higher with some safe-haven buying amid continued worries about the outlook for financial services companies. Euro zone government bonds rose on the soft euro zone economic data.
Trading volume was thin in both the U.S. stock and bond markets before a two-day meeting of Fed policy-makers begins on Tuesday.
U.S. and European stocks were little changed as energy-related stocks rose on rising crude prices and off set fear of more trouble in the financial sector. Exxon Mobil, Chevron and ConocoPhillips led advancing shares on the Standard & Poor's 500 Index <.SPX>, while insurance and banking shares pulled down the broad benchmark index.
The KBW index <.BKX> of large U.S. banks fell 1.8 percent, with all of its 24 components down, after Goldman Sachs' recommendation to sell companies in the financial sector.
Shares of Bank of America Corp <BAC.N> were off more than 3percent, JPMorgan Chase & Co <JPM.N> slid almost 3 percent and Citigroup <C.N> fell about 3.7 percent.
"Banks are weighing on the market. They are down 25-to-28 percent in the past 5-6 weeks," said Steve Goldman, market strategist at Weeden & Co in Greenwich, Connecticut. "There are further bank downgrades today from Goldman and that's making it tougher for the market."
Before 1 p.m., the Dow Jones industrial average <
> was down 15.72 points, or 0.13 percent, at 11,826.97. The Standard & Poor's 500 Index <.SPX> was down 1.89 points, or 0.14 percent, at 1,316.04. The Nasdaq Composite Index < > was down 16.16 points, or 0.67 percent, at 2,389.93.In Europe rising oil prices also bolstered energy shares and pharma also rose, led by Shire's <SHP.L> gains on an upbeat broker note.
But advances were nearly offset by ongoing worries over the health of the banking sector. UBS <UBSN.VX> lost 4.4 percent and Credit Agricole <CAGR.PA> shed 4.5 percent.
The FTSEurofirst 300 <
> index of top European shares closed 0.1 percent higher at 1,222.89 points. The index slipped 3.5 percent last week, dragged lower on the outlook for banks, high oil prices and the spectre of interest rate hikes."Investors have overreacted. Stock prices are unrealistically low after last week's sell-off sparked in part by anticipations of interest rate hikes," said Francois Chevallier, strategist at VP Finance in Paris.
"But macro news out of Europe is not good and signals a strong slowdown that could force the ECB to postpone any rate hikes," he said.
The euro <EUR=> fell 0.62 percent at $1.5508.
The dollar rose against major currencies, with the U.S. Dollar Index <.DXY> up 0.71 percent at 73.501. Against the yen, the dollar <JPY=> was up 0.51 percent at 107.85.
Tension between Israel and Iran spurred buying in crude oil, although cease-fire by rebels halting attacks on facilities in the Niger delta barely tempered the rise after two new attacks over the past week knocked out another tranche of Nigerian output. A weekend meeting of producers and consumers sponsored by Saudi Arabia had little impact on trading, although no bearish news arrived to push prices lower from near-record levels.
U.S. light sweet crude oil <CLc1> rose $2.60 to $137.96.
Gold fell nearly 3 percent in Europe as the dollar firmed against the euro and as sliding oil prices triggered a bout of selling. Silver also fell in gold's wake, sliding almost 5 percent to a session low of $16.56 an ounce.
Trade in U.S. Treasuries was well below average as investors stuck to the sidelines ahead of the Fed's two-day policy meeting later this week.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was barely higher to yield 4.17 percent. The 30-year U.S. Treasury bond <US30YT=RR> rose 11/32 to yield 4.71 percent.
"The Ifo index in Europe came in a bit below expectations and it got people to question whether growth over there is really that strong -- and that is helping Treasuries," said Matthew Moore, economic strategist at Banc of America Securities in New York.
The Fed is expected to hold rates at 2 percent when its meeting concludes on Wednesday, but surging energy and food price inflation has futures markets pricing in at least a pair of rate hikes by year end.
Asian equities dropped to their lowest in three months amid fears of more banking write-downs and most Asian bonds gained as investors sought safety. An exception was India's 10-year federal bond, whose yield rose to the highest in nearly seven years due to inflation concerns.
Tokyo's Nikkei average fell 0.6 percent as Japanese firms' sentiment on business conditions hit a four-year low. (Reporting by Ellis Mnyandu, Steven C.
