Fed finalises stress-test overhaul: capital buffers averaged over two years from 2028, scenarios opened to public comment

US Financials

What happened

The Federal Reserve Board adopted two final rules changing its annual stress test of large banks. The first requires the Board to seek public comment each year on its test scenarios and on significant model changes, and tests banks with large trading operations against two global market shocks a year, using the one that produces the bigger loss. The second sets each firm's stress capital buffer from the average of its two most recent test results, starting in 2028. The Board says the changes cut year-to-year swings in capital requirements by about 50% without materially changing total capital required.

Why it matters for listed companies

The stress capital buffer decides how much common equity each large US bank is required to keep above the minimum, and so how much it can return through dividends and share repurchases. Averaging two years makes that number steadier and easier to plan around, which matters most to the largest banks and to trading-heavy firms whose results moved most from year to year. By the Fed's own estimate total required capital is about the same, so this is a change in predictability, not a release of capital.
