Federal Reserve Finalizes Overhaul of Bank Stress Tests to Boost Transparency and Cut Capital Volatility

WASHINGTON — The Federal Reserve Board on Wednesday finalized a comprehensive package of regulatory changes designed to significantly enhance the transparency and public accountability of its annual bank stress tests, while simultaneously curbing the sharp year-over-year volatility that has historically characterized related capital requirements.

The two final rules, released at 9:00 a.m. EDT, largely mirror the proposed rules originally introduced for public consideration in 2025. Alongside these finalized measures, the central bank also issued a fresh request for public comment on an additional proposal aimed at better capturing the distinct operational differences in how individual banks generate fee income across diverse business models.

The Federal Reserve conducts rigorous annual stress tests to ensure that the nation’s largest and most complex financial institutions maintain capital levels that are more than sufficient to withstand severe economic downturns. By doing so, the central bank aims to guarantee that these institutions retain the operational capacity to continue lending to households and businesses, even in the event of a severe recession. The latest series of modifications builds upon continuous efforts by regulators, following previous announcements in December 2024 to modify the diagnostic testing framework and improve overall banking sector resilience.

"The stress test is an essential component of our regulatory capital framework," said Vice Chair for Supervision Michelle W. Bowman, addressing the significance of the regulatory updates. "Today’s changes preserve its resilience by ensuring that it is transparent, granular, and risk-sensitive. The public will now have greater assurance that the risks banks take will be reflected appropriately in their stress test losses and their capital requirements."

According to the Federal Reserve, the implementation of these combined changes is projected to reduce year-over-year volatility in bank capital requirements by approximately 50 percent. Despite this substantial smoothing effect, the central bank noted that the regulatory adjustments are not expected to materially affect aggregate capital requirements across the banking sector as a whole.

The first of the two final rules introduces a formalized mechanism requiring the Board to invite public input annually regarding the specific stress test scenarios and any material model changes under consideration. This rule also updates the underlying framework that guides the design of hypothetical economic scenarios and formally adopts the specific models that will be utilized for the upcoming 2027 stress test cycle. Furthermore, the final rule enacts several important operational adjustments to the stress test calendar, providing greater predictability for participating institutions.

A notable update within the first final rule involves the global market shock component, which applies a severe set of hypothetical shocks to specific market components for banking organizations with large trading books. Under the revised framework, these specialized trading institutions will now be tested against two distinct global market shock components each year. To determine final outcomes, the Board will utilize the specific shock that produces the largest losses for each individual firm when calculating its stress test results.

The second final rule addresses the mechanics of the stress capital buffer requirements, which dictate the minimum capital cushion banks must maintain above regulatory baselines. Moving forward, the rule requires the Board to average the results from the two most recent annual supervisory stress tests for firms that are subject to the testing requirements in both consecutive years. The central bank announced that it will officially begin averaging these stress capital buffer requirements in 2028. This implementation timeline has been intentionally established to ensure that only models incorporating direct public input are utilized in the calculation process.

In addition to finalizing these regulatory frameworks, the Board issued a specific proposal opening a 60-day public comment period following its publication in the Federal Register. This proposal seeks public feedback on potential revisions to the Board’s noninterest income model, which is designed to improve the stress test’s capability to accurately capture the broad diversity of business models operating across different financial institutions. If ultimately adopted, these proposed adjustments would completely replace the current noninterest income model, which currently projects each bank’s fee income under severe economic stress.
