NEW YORK, June 29 (Reuters) - U.S. stock index futures jumped on Friday after euro zone leaders agreed to allow rescue funds to be used to stabilize the region's banks.
Details of the agreement, which includes the creation of a single supervisory body for euro area banks, remain to be worked out. Still, Italian and Spanish borrowing costs fell as market expectation for any action during a two-day European Union summit had all but vanished.
"We've gotten used to being underwhelmed by the outcomes so with little-to-no expectations for success, the fact that it appears we are going to get something substantial is a real important positive for the market in the near term," said Art Hogan, managing director of Lazard Capital Markets in New York.
"It's inching closer to a banking union and the closer we get to a banking union would put (the EU) well on the road to a fiscal union."
Financial stocks could attract the most buyers in U.S. markets as the risk of exposure to their European peers diminishes. The Select Sector Financial SPDR rose 1.6 percent in premarket trading.
A more than 1 percent jump in the euro against the U.S. dollar could also entice investors into commodity-related sectors like basic materials and energy. The Select Sector Energy SPDR added 1.6 percent.
Equities and other risky assets have recently been weighed down by concerns that stubbornly high borrowing costs in Spain and Italy could force the fourth- and third-largest economies in the bloc to seek bailouts.
S&P 500 futures jumped 20 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 131 points, and Nasdaq 100 futures added 35 points.
The steep gains trimmed a quarterly decline in S&P futures to about 4 percent. Futures have, so far, gained 2.5 percent in June.
