"Serious risk" that credit of U.S. banks will deterioriate if Eurozone crisis starts to spread

U.S. banks face a “serious risk” that their creditworthiness will deteriorate if Europe’s debt crisis deepens and spreads beyond the five most-troubled nations, Fitch Ratings said.

“Unless the euro zone debt crisis is resolved in a timely and orderly manner, the broad credit outlook for the U.S. banking industry could worsen,” the New York-based rating company said yesterday in a statement. Even as U.S. banks have “manageable” exposure to stressed European markets, “further contagion poses a serious risk,” Fitch said, without explaining what it meant by contagion.
