All but one of major U.S. banks meet Fed's stress test hurdle

WASHINGTON (Reuters) - U.S. banks generally have big enough capital buffers to withstand a drastic economic downturn, the Federal Reserve said on Thursday, announcing that 29 out of 30 major banks met the minimum hurdle in its annual health check.

All of the biggest banks, which include U.S. units of foreign banks, except for Zions Bancorp , stayed above the 5 percent requirement for top-tier capital in the latest round of stress tests.
