America’s biggest banks are cleared for billions in stock buybacks after most of them passed the second round of Fed stress tests this week.

In all, 31 of 33 passed — Deutsche Bank and Banco Santander were the only failures — including all eight systematically important banks. That means more dividends and buybacks are on the way.
