NEW YORK (AP) — JPMorgan Chase and Goldman Sachs need better plans for coping with a severe recession, the Federal Reserve said Thursday, giving the banks until September to revise them.

The announcement came as part of the Fed’s so-called “stress tests,” its annual check-up of 18 of the country’s big banks. The government runs the tests to see how the banks would fare in a bad economic downturn. As a result of the tests, it also tells each bank whether it’s allowed to raise its dividend, the quarterly payout it gives to stockholders, or buy back more of its own shares.
