The Federal Reserve has put forward proposals to enhance the transparency of its annual bank stress testing framework, opening a formal public comment period on changes that would provide large financial institutions and the broader public with significantly greater visibility into the models, assumptions, and scenarios that underpin the regulator's supervisory stress tests. The proposals were published on 24 October 2025, through a press release on the Federal Reserve's website, and signal a substantive willingness to revise aspects of a framework that has been a defining feature of US bank supervision since the Comprehensive Capital Analysis and Review exercises were first introduced in the immediate aftermath of the 2008 financial crisis.
The Federal Reserve stated in the press release that the proposed changes are designed to align the stress testing framework with current economic conditions, an acknowledgement that the macroeconomic and financial environment has shifted materially since the methodology underpinning the existing framework was developed. Stress tests are constructed to assess whether the largest US banks retain sufficient capital buffers to absorb severe hypothetical losses without impairing their ability to lend; ensuring that the scenarios and analytical models used in those tests accurately capture the risks present in the actual economy is therefore a foundational requirement for the framework to fulfil its supervisory objectives.
GREATER MODEL AND SCENARIO DISCLOSURE PROPOSED
The substantive core of the Fed's proposals concerns the disclosure of stress test models and the scenarios used to generate hypothetical loss projections. The current framework has historically provided limited granular detail on the specific modelling assumptions and intermediate analytical steps through which scenario inputs are translated into bank-level capital shortfall estimates. Supervised institutions have argued that this opacity makes it difficult to understand, anticipate, or engage constructively with the methodology underlying their stress test outcomes, creating uncertainty in capital planning that can result in institutions maintaining larger capital buffers than prudential requirements alone would necessitate.
Greater transparency over the analytical methodology would allow supervised banks, independent academics, and other external commentators to engage more substantively with the intellectual basis of the stress test results. The public comment period provides all interested stakeholders — including banks, investors, trade associations, consumer advocacy groups, and academic researchers — with a formal and structured channel through which to submit views on the specific proposals before the Federal Reserve moves toward finalising any changes.
COMMENT PERIOD OPENS BROADER FRAMEWORK DEBATE
The decision to invite public comment on stress test methodology reflects a broader and ongoing conversation within US bank supervision about maintaining the analytical rigour of the post-crisis capital framework while ensuring that its design remains proportionate, transparent, and responsive to evolving economic realities. The stress testing framework has periodically been subject to legal and technical challenges from the industry, and the Federal Reserve's willingness to engage formally and publicly with its methodology signals a substantive rather than merely procedural response to those pressures.
The Federal Reserve has not indicated a specific timeline for finalising changes following the conclusion of the public comment period, nor has it quantified any potential implications for the capital requirements of the banks subject to the annual stress testing exercise. Those details are expected to emerge as the rulemaking and consultative process advances and the Board of Governors considers the full range of responses submitted by stakeholders during the consultation window.
