NEW YORK, June 23 (Reuters) - Oil rose on Monday after a widely anticipated Saudi Arabian energy conference over the weekend failed to bring optimism to revive recently battered global equity markets gripped by fears of inflation and slow growth.
The dollar rose against the euro as the high energy costs took a toll on German business sentiment and manufacturing and service sectors contracted in the euro zone, denting the case for higher interest in the monetary bloc.
The Federal Reserve meeting of policy-makers this week is likely to bring stern talk about the risks of rising inflation and a break in the interest rate cutting that started last year.
U.S. Treasury debt prices were mixed 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 the Fed's two-day meeting that begins Tuesday.
U.S. and European stocks closed little changed as energy-related stocks rose on rising crude prices and off set fear of more trouble in the financial sector. Exxon Mobil <XOM.N> and Chevron <CVX.N> were the biggest contributors to the blue-chip Dow.
The blue-chip Dow and broad market S&P 500 were little changed. The Dow Jones industrial average <
> closed off 0.33 points, or breakeven, at 11,842.36. The Standard & Poor's 500 Index <.SPX> rose 0.08 points, or 0.01 percent, at 1,318.01. The Nasdaq Composite Index < > fell 20.35 points, or 0.85 percent, at 2,385.74.The KBW index <.BKX> of large U.S. banks fell 2.9 percent, with all of its 24 components down, after Goldman Sachs' recommendation to sell companies in the financial sector as well as consumer discretionary stocks due to economic worries.
The Standard & Poor's retail index <.RLX> fell 2.5 percent.
An analyst at Banc of America Securities said it expects Merrill Lynch <MER.N> and UBS AG <UBSN.VX> to write down $3.5 billion and $7 billion, respectively, in the second quarter.
Shares of Bank of America Corp <BAC.N> were off 4.5 percent, JPMorgan Chase & Co <JPM.N> slid 2.5 percent and Citigroup <C.N> fell 4 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."
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 dollar rose against major currencies, with the U.S. Dollar Index <.DXY> up 0.63 percent at 73.437. Against the yen, the dollar <JPY=> was up 0.48 percent at 107.81.
The euro <EUR=> fell 0.53 percent at $1.5521.
Oil rose as Nigerian supply disruptions and escalating tensions between Israel and Iran outweighed Saudi Arabia's pledge to raise output and keep markets well-supplied.
U.S. crude <CLc1> settled at $136.74 a barrel, up $1.38. London Brent crude <LCOc1> was up $0.99 at $136.24 a barrel.
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. gold futures plunged as much as 3 percent in heavy volume.
The August contract for gold <GCQ8> in New York settled down $16.50 at $887.20 an ounce.
Selling by funds and the squaring of positions ahead of the Fed's policy-setting this week pummeled gold futures, said independent floor trader Jonathan Jossen.
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> fell 2/32 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.
