The 34 lenders the Fed oversees with more than $100 billion in assets would suffer a combined $612 billion in losses under a hypothetical severe downturn, the central bank said, but that would still leave them with roughly twice the amount of capital required under its rules.

As a result, banks including JPMorgan Chase, Bank of America, Wells Fargo, Citigroup, Morgan Stanley and Goldman Sachs can use their excess capital to issue dividends and buybacks to shareholders.

Under its annual "stress test" exercise established following the 2007-2009 financial crisis, the Fed assesses how banks' balance sheets would fare against a hypothetical severe economic downturn. The results dictate how much capital banks need to be healthy and how much they can return to shareholders.

Banks must wait until after markets close at 4:30 p.m. EDT (2030 GMT) on Monday to announce their capital distribution plans.

While the 2022 scenarios were devised before Russia's invasion of Ukraine and the current hyper-inflationary outlook, they should give investors and policymakers comfort that the country's banks are well-prepared for what economists warn is a potential U.S. recession later this year or next.

The 34 banks suffered heavy losses in this year's scenario, which saw the economy contract 3.5%, driven in part by a slump in commerical real estate asset values, and the jobless rate jumping to 10%.

But even then, the Fed said aggregate bank capital ratios were still roughly twice the minimum amount required by regulators.

In 2020 the Fed changed how the test works, scrapping its "pass-fail" model and introducing a more nuanced, bank-specific capital regime.
