U.S. stocks were set to rally at the open Friday, after European leaders reached a deal on struggling eurozone banks.
Optimism was further fueled by the latest reading on personal income in the United States, which increased in May by 0.2% -- slightly higher than what was expected.
Dow Jones industrial average, S&P 500 and Nasdaq futures were all about 1% higher. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
Friday also marks the end of the first half of the year. The three major indexes were on pace to close out with gains between 3% and 9%.
At the two-day European Union summit in Brussels, EU leaders struck a "breakthrough" deal early Friday to ease the recapitalization of struggling banks, which should help draw the eurozone back from the brink of its debt crisis.
The deal includes a European banking union with capital injections that will go straight into banks. This will have the potential to reduce what bond analyst Elisabeth Afseth called "the bank-sovereign negative feedback loop."
The Investec analyst in London said the loop starts when a nation borrows to recapitalize its troubled banks, which then increases the country's debt, pushes up bond yields, reduces bond values and forces banks to require even more capital.
"It's an important step," Afseth said, but she remains skeptical. "You have to be a little bit concerned where the funds are coming from. They could potentially run out quite quickly."
EU leaders are hoping for implementation of the bank agreement by July 9, according to a statement released by the group.
European stocks surged in afternoon trading on the news. Britain's FTSE 100 added 1.9%, the DAX in Germany jumped 3.3% and France's CAC 40 rallied 3.1%.
Meanwhile, Italian and Spanish 10-year bond yields fell, with Spanish bonds at 6.66% and Italian bonds at 6.03%. Both were previously flirting with 7% rates, which Spanish Prime Minister Mariano Rajoy called unsustainable.
