* All eyes on Fed, markets await statement
* Dollar weakens against major currencies
* Euro zone bond sale goes well (Updates with European markets close)

NEW YORK, Sept 21 (Reuters) - World stocks and the dollar fell on Tuesday as investors awaited a Federal Reserve statement that was expected to give some hint at whether the central bank thinks the fragile U.S. economy needs a fresh infusion of cash.
U.S. stocks were modestly lower as caution over the Fed meeting overshadowed upbeat housing data. U.S. government bond prices rose, however, supported by speculation the Fed will retain, or even consider enhancing, its accommodative monetary stance.
There was little expectation of any firm moves from the Federal Reserve policymakers, but, as ever, the wording of their statement, expected around 2:15 p.m. (1815 GMT), would be key.
At issue is how close the stumbling U.S. economy is to requiring the return of quantitative easing -- effectively printing money to buy mortgage bonds and securities.
The Fed is expected to renew a promise to keep its portfolio from shrinking but take no new steps to ease its monetary policy.
The central bank acknowledged in August that the U.S. recovery had lost momentum, and Fed Chairman Ben Bernanke said it would renew efforts to stimulate growth if the outlook soured appreciably. For details, see [
]"The latest incoming data gives the Fed a little bit more leeway," said Alan Lancz, president of Alan B. Lancz & Associates Inc in Toledo, Ohio.
"Any economic projections or the breakdown in the vote of the committee members will be what most investors will be looking at," he said.

The Nasdaq Composite Index < > was down 5.65 points, or 0.24 percent, at 2,350.18.World stocks as measured by MSCI<.MIWD00000PUS> fell 0.14 percent while the pan-European FTSEurofirst 300 closed 0.3 percent lower ahead of the Fed's meeting. Technology stocks also dragged down the market. Nokia <NOK1V.HE> fell 4.5 percent after the world's top cellphone maker said it would again delay its flagship N8 model smartphone.
Earlier, Japan's Nikkei <

"Investors are waiting on the sidelines. Yesterday the market went up in anticipation that the Fed can do something about the economy, but I think people are ignoring the macroeconomic condition," said Koen De Leus, economist at KBC Securities in Brussels.
DOLLAR DOWN
The euro <EUR=> was up half a percent at $1.3129, also supported by solid demand at euro zone debt sales in some of the troubled peripheral economies, which have appeared to be heading into crisis again.
What had been increasing pressure on some euro zone debt eased though with an Irish bond auction going smoothly and a successful sale of Greek T-bills.
Greece sold 390 million euros ($512 million) of 3-month T-bills at an average yield of 3.98 percent, down from 4.05 percent in a July 20 sale. Overseas investors bought 72 percent, a sign of relative confidence.
Ireland sold 1.5 billion euros in an auction of 2014 and 2018 bonds, at the top of its target range. Their yields -- 4.767 percent and 6.023 percent respectively -- were well below those seen for the bonds on secondary markets on Monday.
"Very strong auctions from Greece and Ireland. This along with the spread tightening we've seen this morning and the strong bid-cover ratios means this funding round for Ireland and Greece has been passed convincingly," said Peter Chatwell, rate strategist at Credit Agricole in London.
Against the Japanese yen, the dollar <JPY=> was down 0.37 percent at 85.35 from a previous session close of 85.680.
