NEW YORK, Dec 18 (Reuters) - Global equity markets rose on Wednesday on a strengthening U.S. housing market and improving German business morale, while U.S. Treasury prices fell ahead of a Federal Reserve decision to hold off or finally begin to unwind its stimulus.
U.S. housing starts in November surged to their highest level in nearly six years as they jumped 22.7 percent in their biggest gain since January 1990, the Commerce Department said.
The housing news dovetails with other recent economic data, including growth in jobs and retail sales, which might nudge the Fed into announcing a pullback to its bond-buying program when it concludes a two-day policy-setting meeting today.
Fed Chairman Ben Bernanke will follow the 2:00 p.m. EST (1900 GMT) announcement with his final press conference at the helm of the U.S. central bank at 2:30 p.m.
Many expect the Fed to stand pat with its asset purchase of $85 billion a month and will wait to "taper" until either January or March when policymakers again meet.
"If they taper, the market might perceive this as 'the economy is good,' and if they don't, everybody still likes the stimulus," said Kim Forrest, senior equity research analyst, Fort Pitt Capital Group in Pittsburgh.
MSCI's all-country world equity index rose and the pan-European FTSEurofirst 300 index of leading regional shares extended gains after think tank Ifo reported German business morale in December hit its highest level since April 2012.
The FTSEurofirst 300 rose 0.94 percent and the euro zone's blue-chip Euro STOXX 50 index jumped 1.02 percent.
The Ifo report was another sign that growth in Europe's largest economy may accelerate next year after a relatively subdued 2013.
U.S. stocks also rose, with the Nasdaq rebounding after trading mostly lower in the morning.
The Dow Jones industrial average rose 56.64 points, or 0.36 percent, to 15,931.9. The S&P 500 gained 3.15 points, or 0.18 percent, to 1,784.15 and the Nasdaq Composite added 0.262 points, or 0.01 percent, to 4,023.942.
U.S. government debt fell on the housing data.
Benchmark 10-year Treasury notes fell 10/32 in price to yield 2.8793 percent, toward the high end of a recent range.
German bonds initially rose after news that Germany plans to cut debt issuance to the lowest level since 2007 next year. But gains were limited as investors awaited the Fed's decision.
German Bund futures slipped 1 tick to 140.28, after earlier rising as high as 140.49.
The dollar rose against the euro, helped by the rise in U.S. Treasury yields.
The euro slipped 0.06 percent to $1.3766, while the dollar index rose 0.03 percent to 80.061.
Brent oil futures held above $108 a barrel, with investors reluctant to lock in positions ahead of the Fed decision.
Brent crude rose 41 cents to $108.85 a barrel, and U.S. oil rose 45 cents to $97.67 a barrel.
