* World stocks bounce higher on U.S. data
* Greek debt, euro under pressure
* Wall Street set for mild gains
By Jeremy Gaunt, European Investment Correspondent
LONDON, April 26 (Reuters) - World stocks bounced sharply higher on Monday, boosted by a raft of U.S. data showing economic recovery gathering strength, but crisis-hit Greece's debt came under renewed pressure.
The euro fell as questions remained about Friday's decision by the Greek government to turn to its European Union partners and the International Monetary Fund for help.
Wall Street looked set to open with mild gains.
Greece tried to reassure investors on Sunday that aid would arrive in time to avert the euro zone's first sovereign debt default, despite signs that a 45 billion-euro ($60.49 billion) EU-IMF package would have to be bigger.
But the premium investors demand to buy Greek government bonds rather than euro zone benchmark Bunds hit a new 12-year high.
Equity investors, however, were buoyed by solid improvement in U.S. economic data on Friday.
World stocks as measured by MSCI <.MIWD00000PUS> were up 0.6 percent. The pan-European FTSEurofirst 300 <
> gained 1 percent and Japan's Nikkei < > closed 2.3 percent higher.New U.S. home sales rose at their fastest pace in 47 years in March and new orders for durable goods grew strongly, helping U.S. stocks to a 19-month high.
"U.S. economic data, and other global data has been driving the market higher," said Bernard McAlinden, investment strategist at NCB Stockbrokers.
EURO FALLS
Elsewhere, however, it was Greece making the running.
The euro fell and the spread between Greek and German 10-year government bond yields hit a new 12-year high of 670 basis points.
"The market is looking for any fresh news in regards to Greece; we will only get a positive reaction if we get some firm details but that may take some time," said Christian Lawrence, currency strategist at RBC Capital Markets.
The European Commission said there was no specific deadline for a deal to be finalised.
The euro fell half a percent on the day against sterling <EURGBP=D4>, while the single currency also fell 0.1 percent against the yen at 125.14 yen <EURJPY=R>.
It was down half a percent against the dollar at $1.3321 <EUR=>.
On fixed income markets, other peripheral euro zone countries were also coming under pressure. Portuguese/German yield spreads widened to a lifetime level.
