(Recasts, adds Wall Street outlook)

LONDON, May 15 (Reuters) - Two-year euro zone bond yields hit a four-month high on Thursday after data showed the region grew more strongly than expected in the first quarter, while European stocks steadied after an early sell-off.
The 15-nation bloc's economy grew 0.7 percent in the January-March period from the previous quarter for a 2.2 percent annual rise. Amongst national data, Germany offered a blockbuster reading -- its economy expanded 1.5 percent in the first quarter, the strongest growth since 1996.
Separate data showed euro zone inflation eased in April to 3.3 percent from an all-time peak of 3.6 percent in March.
Analysts say growth data, although not forward-looking, showed the region's economy, especially in Germany is holding up in the face of a strong euro and the credit turmoil which started in August.
"It is quite a sensation that growth has come out so strongly," said Ulrike Kastens, economist at private bank Sal. Oppenheim.
Two-year euro zone government bond yields rose as high as 4.016 percent <EU2YT=RR>, their highest since January. Euro zone interest rate futures are beginning to price in a slim possibility of an interest rate hike from the current 4 percent.
The FTSEurofirst 300 index <

The June Bund future <FGBLM8> was down 73 ticks as safe-haven flows diminished.
But even with Thursday's good news, few believe the euro zone will emerge unscathed from a U.S. economic slowdown. Trouble in the banking sector, reeling from the nine-month-old credit crisis, threatens to hit lending and weigh on consumer confidence.
"The shadow of Goldilocks, long pronounced dead, has briefly been spotted again somewhere close to Frankfurt... Unfortunately, this benign 'not too hot, not too cold' set of data won't last long," Holger Schmieding, economist at Bank of America, said in a note to clients.
"Upcoming data will likely show a - hopefully temporary - collapse in GDP growth and a spike in head line inflation to a new record instead."
U.S. stock futures were up 0.2 percent <SPc1>, pointing to a stronger start on Wall Street which has a slew of earnings from key retailers such as JC Penney <JCP.N> along with tech giant Hewlett-Packard <HPQ.N>.
Emerging sovereign spreads <11EMJ> tightened 1 basis point while emerging stocks <.MSCIEF> rose 0.7 percent.
The dollar was steady on the day <.DXY> against a basket of six major currencies.
U.S. light crude oil <CLc1> rose 0.7 percent to $125.03 a barrel having hit an all-time high near $127 on Tuesday.
Gold <XAU=> ticked higher to $866.00 an ounce.
