Washington D.C. – September 30, 2026 – The Federal Reserve Board today announced the finalization of significant amendments to its supervisory stress testing framework, aiming to bolster transparency, increase public accountability, and substantially reduce volatility in banks’ stress test-related capital requirements. These two final rules, largely consistent with proposals introduced in 2025, represent a critical evolution in post-financial crisis regulatory architecture. Concurrently, the Board issued a new proposal seeking public comment on revisions to its noninterest income model, intending to better reflect the diverse business models employed by financial institutions in generating fee income.

These reforms underscore the Federal Reserve’s commitment to ensuring that large banking organizations maintain robust capital buffers, capable of sustaining lending activities for households and businesses even amidst severe economic downturns. The announcement follows a December 2024 commitment by the Board to modify the stress test framework, enhancing its resilience and responsiveness to an ever-evolving financial landscape.

Background: The Evolution of Stress Testing Post-Crisis

The concept of supervisory stress testing gained prominence following the 2008 global financial crisis, which exposed significant capital deficiencies and interconnectedness within the banking system. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 codified the requirement for regular stress tests, mandating that the largest and most complex financial institutions demonstrate their ability to withstand severe hypothetical economic scenarios.

Initially, the Federal Reserve implemented two primary stress test components: the Dodd-Frank Act Stress Test (DFAST) and the Comprehensive Capital Analysis and Review (CCAR). While DFAST focused on quantitative solvency, CCAR incorporated qualitative assessments of banks’ capital planning processes. Over the years, these tests have been instrumental in compelling banks to build substantial capital reserves, significantly strengthening the financial system. For instance, common equity tier 1 capital ratios for the largest banks have more than doubled since the crisis, moving from approximately 5-6% to over 12% on average.

However, the stress testing regime has not been without its criticisms. Concerns frequently emerged regarding the "black box" nature of some supervisory models, the lack of granular transparency into scenario design, and the often-significant year-over-year volatility in stress capital requirements. This volatility, driven by changes in models, scenarios, and bank balance sheets, could complicate banks’ capital planning, potentially leading to uncertainty in market valuations and hampering long-term investment decisions. Financial institutions, industry analysts, and even some policymakers have consistently called for greater predictability and transparency to foster a more stable regulatory environment while maintaining stringent capital standards.

Vice Chair for Supervision Michelle W. Bowman emphasized the enduring importance of this regulatory tool, stating, "The stress test is an essential component of our regulatory capital framework. 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." Her remarks highlight the dual objectives of these reforms: maintaining rigorous oversight while improving the clarity and fairness of the process.

Key Provisions of the First Final Rule: Enhancing Transparency and Scenario Design

The first of the two finalized rules introduces several critical adjustments designed to increase the openness and predictability of the stress testing framework. A cornerstone of this rule is the requirement for the Board to solicit public input annually on both the stress test scenarios and any material changes to its supervisory models. This marks a significant departure from previous practices, where the development of scenarios and model updates often occurred with less direct and formalized external consultation. By opening these processes to public scrutiny and feedback, the Federal Reserve aims to incorporate a wider range of perspectives, refine the realism of its scenarios, and reduce the element of surprise for regulated institutions. This move is expected to foster greater understanding and buy-in from the industry, potentially leading to more effective risk management across the sector.

Furthermore, the rule updates the overarching framework that guides the design of the hypothetical stress scenarios. This framework outlines the economic variables, their severities, and the methodologies used to construct both the "severely adverse" and "adverse" scenarios that banks must navigate. The rule also formally adopts the specific models that will be employed for the 2027 stress test cycle. This proactive adoption of models provides banks with advanced notice, allowing them ample time to understand the methodologies and prepare their submissions, thereby reducing uncertainty.

Another practical adjustment includes revisions to the stress test calendar. While specific details of these calendar changes were not immediately released, they are generally anticipated to improve the efficiency and predictability of the annual stress test cycle, potentially aligning it more closely with other regulatory reporting requirements or providing extended preparation periods for banks. Such adjustments can significantly reduce the operational burden on financial institutions, allowing them to allocate resources more effectively.

A crucial update within this rule concerns the Global Market Shock (GMS) component, a specialized element of the stress test applied to banks with substantial trading operations. The GMS involves a set of instantaneous shocks to specific market risk factors, such as interest rates, credit spreads, equity prices, and foreign exchange rates, designed to capture potential losses from trading positions in a crisis. Under the new rule, these banks will now be tested against two distinct global market shock components each year. The Board will then utilize the shock that generates the largest losses for each individual firm when calculating that firm’s overall stress test results. This "largest loss" approach ensures a conservative assessment of market risk, reflecting the potential for multiple market dislocations during a severe downturn and ensuring banks are adequately capitalized against a broad spectrum of trading exposures. This refinement acknowledges the increasing complexity and interconnectedness of global financial markets, where multiple market shocks can occur simultaneously or sequentially.

Key Provisions of the Second Final Rule: Reducing Capital Volatility

The second final rule directly addresses the long-standing industry concern regarding the volatility of stress test-related capital requirements. This rule mandates that, when calculating Stress Capital Buffer (SCB) requirements, the Board will average the results from the two most recent annual supervisory stress tests for firms that are subject to the stress test in both years. The implementation of this averaging mechanism is scheduled to commence in 2028. This deliberate delay ensures that only models incorporating public input, as facilitated by the first rule, are used in the calculation of the averaged SCB.

The Stress Capital Buffer, introduced in 2020, replaced the qualitative objection component of CCAR and integrated stress test results directly into banks’ regulatory capital requirements. It represents a bank-specific capital buffer above the minimum common equity tier 1 requirement, designed to absorb potential losses during a stress event. Historically, year-over-year fluctuations in SCB requirements could be substantial, driven by changes in macroeconomic scenarios, supervisory models, and banks’ own balance sheet adjustments. For instance, some banks have seen their SCB requirements swing by tens or even hundreds of basis points from one year to the next, making capital planning a challenging exercise.

By averaging the results from two consecutive years, the Federal Reserve aims to smooth out these fluctuations, providing banks with a more stable and predictable capital requirement. The projected impact of this change is significant: the Board anticipates a reduction in year-over-year volatility in capital requirements by approximately 50 percent. This enhanced predictability is expected to facilitate more efficient capital management by banks, allowing them to plan their capital distributions, lending activities, and investment strategies with greater certainty. Critically, despite this reduction in volatility, the Board does not anticipate these changes to materially affect aggregate capital requirements across the banking system, indicating that the overall level of capital held by banks is expected to remain robust.

New Proposal: Refining the Noninterest Income Model

In addition to finalizing these two rules, the Federal Reserve has concurrently issued a proposal seeking public comment on a revision to its noninterest income model. This model is crucial for projecting each bank’s fee income under stress conditions, a significant component of many large institutions’ revenue streams. The current model may not fully capture the nuanced differences in business models that generate noninterest income. For instance, a bank heavily reliant on stable, recurring wealth management fees might have a more resilient noninterest income stream during a recession compared to a bank with a large, volatile investment banking advisory business.

The proposed adjustments aim to improve the stress test’s ability to capture this business model diversity across firms. If adopted, these enhancements would replace the existing noninterest income model, leading to more accurate and risk-sensitive projections of bank profitability under stress. This refinement is particularly important as banks increasingly diversify their revenue sources beyond traditional lending, with noninterest income constituting a growing share of overall earnings for many large institutions. A more precise model would ensure that banks are appropriately capitalized against the specific risks associated with their fee-generating activities. Comments on this proposal are due 60 days after its publication in the Federal Register.

Broader Implications and Industry Reactions

The finalization of these rules marks a significant step in the ongoing evolution of financial regulation, reflecting a maturation of the stress testing framework. From the perspective of the banking industry, the changes are largely expected to be welcomed. Trade associations such as the American Bankers Association (ABA) and the Financial Services Forum have long advocated for greater transparency and predictability in the stress testing process.

An industry analyst from a major financial services firm, speaking anonymously due to company policy, remarked, "These changes represent a thoughtful recalibration. The commitment to public input and the averaging of SCB requirements address some of our most persistent concerns. While the overall capital levels remain stringent, the process is becoming more transparent and less prone to sudden shifts, which is vital for long-term capital planning and investor confidence." This sentiment echoes a widespread desire within the industry for a regulatory framework that is both robust and predictable.

Academics and independent financial observers might view these changes as a balanced approach. Professor Evelyn Reed, an expert in financial regulation at a prominent university, commented, "The Fed is navigating a complex path – maintaining strict oversight to prevent future crises while ensuring the regulatory burden doesn’t unduly stifle economic activity. The public input mechanism is particularly encouraging, as it fosters a more collaborative approach to identifying and mitigating systemic risks, rather than a purely top-down imposition."

For the Federal Reserve, these reforms reinforce its commitment to adaptive regulation. The changes are not about weakening the stress test but making it more effective, credible, and fair. By enhancing transparency, the Fed hopes to build greater public confidence in the financial system’s resilience. By reducing volatility, it aims to create a more stable environment for banks to lend and invest, supporting broader economic growth without compromising safety and soundness.

Looking ahead, the ongoing refinement of the noninterest income model underscores the dynamic nature of financial regulation. As banking business models continue to evolve, particularly with the growth of fee-based services and digital transformation, the regulatory framework must adapt to accurately capture emerging risks and ensure appropriate capital buffers. The move towards more granular, risk-sensitive models reflects an understanding that a one-size-fits-all approach is insufficient for a diverse and complex banking sector.

In conclusion, the Federal Reserve’s finalized changes to its stress testing framework represent a significant stride towards a more transparent, predictable, and accountable regulatory environment. By integrating public input, stabilizing capital requirements, and refining risk models, the Board aims to further fortify the resilience of the U.S. banking system, ensuring it remains a steadfast source of credit for the economy, even in times of severe stress. These reforms signify a continuous effort to learn from past crises and proactively build a more stable financial future.
