* Euro rebounds versus U.S. dollar on ECB bond-buying talk
* Global stocks rally on signs of stronger economic growth
* Oil prices gain on weak dollar, upbeat U.S. data (Adds close of U.S. markets)

NEW YORK, Dec 2 (Reuters) - The euro rebounded against the U.S. dollar on Thursday and global stocks rallied as talk that the European Central Bank had increased its buying of sovereign debt and recent upbeat economic data lifted sentiment.
Wall Street posted its biggest two-day gain since September and crude oil ended the session at its highest level in 25 months as concerns about the European debt crisis eased and a weaker dollar prompted investors to buy riskier assets.
Investors also cheered upbeat U.S. data on retail sales and housing, the latest signs that the recovery was in fuller swing. Copper notched its largest three-day gain since July.
Disappointment that ECB President Jean-Claude Trichet did not announce a more aggressive policy response to ease the debt crisis initially weakened stocks and the euro. But traders said the ECB was buying Portuguese and Irish debt at a modestly higher rate than of late, bolstering sentiment.
U.S. gold futures were on the verge of breaking above $1,400 an ounce, but safe-haven buying faded after the ECB offered a liquidity safety net for vulnerable banks and the U.S. data pointed to an improving economy.
Bank stocks led the rally on Wall Street after Goldman Sachs said improving economic conditions will favor that sector. For details, see [

"The fears had been centered on Europe. That seems to have stabilized," said Mark Bronzo, portfolio manager at Rydex-SGI in Irvington, New York. "Now the focus is on what domestic and international growth will look like. People are betting that growth will be better than people had feared."

With the ECB's meeting concluded, traders shifted their focus to U.S. labor market data due on Friday. The government is expected to report that nonfarm payrolls rose 140,000 last month, according to a Reuters survey.
Marc Chandler, global head of currency strategy at Brown Brothers Harriman in New York, said there does not seem to be any reason not to look for a relatively robust jobs report.
The string of data for the past several weeks has been not only better than expected but also suggested some modest acceleration of the U.S. economy, he wrote.
"There is some risk that the work week and hourly earnings, important elements of the report, may not show the same improvement as the job creation, but on balance a strong U.S. jobs report is likely," Chandler said.
Oil prices rose in anticipation of strong demand ahead.
U.S. crude for January delivery <CLc1> settled up $1.25, or 1.44 percent, at $88 a barrel, the highest since October 2008.

The benchmark 10-year U.S. Treasury note <US10YT=RR> was down 9/32 in price to yield a hair under 3.0 percent.
"The market is recalibrating itself for a higher level of growth," said Mark Pawlak, market strategist at Keefe, Bruyette & Woods in New York.
