Washington D.C. – September 30, 2026 – The Federal Reserve Board today announced the finalization of significant amendments to its supervisory stress test framework, aiming to bolster the transparency and public accountability of the process while simultaneously mitigating volatility in the resulting capital requirements for large financial institutions. These two comprehensive final rules, largely consistent with proposals initially put forth in 2025, represent a pivotal evolution in the post-financial crisis regulatory landscape. Concurrently, the Board has initiated a public comment period for a new proposal designed to more accurately reflect the distinct business models employed by banks to generate fee income, signaling a continuous commitment to refining its supervisory tools.

The Genesis of Stress Testing: A Post-Crisis Imperative

The foundational principle underpinning the Federal Reserve’s stress tests, formally known as the Comprehensive Capital Analysis and Review (CCAR) and Dodd-Frank Act Stress Tests (DFAST), remains steadfast: to ensure that the nation’s largest banks maintain sufficient capital reserves to continue lending to households and businesses, even under conditions of severe economic downturn. This robust framework was established in the aftermath of the 2008 global financial crisis, a period that exposed critical vulnerabilities in the banking sector’s resilience and capital adequacy. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 codified the mandate for these annual assessments, transforming them into a cornerstone of financial stability.

Initially, these tests were groundbreaking, compelling banks to project losses across their portfolios under hypothetical adverse scenarios designed by the Federal Reserve. Over the years, the methodology has undergone iterative refinements, including the introduction of the Stress Capital Buffer (SCB) in 2020. The SCB, which integrates the results of the supervisory stress test directly into a firm’s minimum capital requirements, replaced the qualitative capital planning component of CCAR, streamlining the framework and enhancing its risk sensitivity. The December 2024 announcement by the Board to further modify the test underscored a continuous commitment to improving its resilience and adapting to evolving financial risks. Today’s finalized rules represent the latest, and arguably one of the most significant, advancements in this ongoing evolution, aiming to address critiques regarding transparency and year-over-year variability.

Enhancing Transparency and Methodological Rigor: The First Final Rule

The first of the two finalized rules introduces a series of measures specifically designed to enhance the transparency and public accountability of the stress testing process. A cornerstone of this rule is the new requirement for the Board to solicit annual public input on both the hypothetical stress test scenarios and any material changes to its underlying models. This move is expected to significantly demystify the "black box" perception that has sometimes shadowed the stress testing methodology. By opening channels for external feedback from academics, industry participants, and consumer advocates, the Federal Reserve aims to foster greater understanding, legitimacy, and ultimately, confidence in the stress test results. This annual public engagement mechanism will likely involve publishing detailed descriptions of proposed scenarios and model adjustments, followed by periods for formal comment, potentially including public forums or roundtables.

Furthermore, this rule updates the overarching framework that guides the design of these hypothetical scenarios. The scenarios typically involve severe global recessions, sharp increases in unemployment, significant declines in asset prices, and disruptions in credit markets. The updated framework will likely provide more detailed guidelines on the economic variables considered, the severity calibration, and the types of risks that scenarios should encompass, ensuring that future tests remain relevant and comprehensive in capturing emerging threats to financial stability. For instance, scenarios might increasingly incorporate elements like cyber risk, climate-related financial risk, or disruptions in specific market segments like commercial real estate, reflecting a broader understanding of systemic vulnerabilities.

Critically, the rule formally adopts the models that will be employed for the upcoming 2027 stress test cycle. These models are sophisticated econometric tools used to project losses on various portfolios (e.g., credit cards, mortgages, corporate loans, trading assets) and pre-provision net revenue under the adverse economic conditions of the stress scenarios. The adoption of these models, presumably informed by extensive internal validation and now subject to public scrutiny, signifies a new standard of rigor and transparency for the quantitative heart of the stress test.

Minor, yet impactful, adjustments have also been made to the stress test calendar. These modifications are intended to optimize the timeline for data submission, analysis, and publication, potentially providing banks with clearer deadlines and allowing more time for their internal capital planning processes to align with the regulatory schedule. Such calendar adjustments often aim to reduce operational burdens on banks while maintaining the integrity and timeliness of the supervisory review.

Perhaps one of the most significant technical updates within this rule pertains to the global market shock (GMS) component. The GMS is a highly specific and severe set of shocks applied to banks with substantial trading operations, targeting various market risk factors such as equity prices, interest rates, credit spreads, foreign exchange rates, and commodity prices. Previously, these banks were tested against a single GMS. The new rule mandates that these firms will now be tested against two global market shock components each year. The Board will then utilize the shock that generates the largest losses for each individual firm when calculating its stress test results. This dual-shock approach is designed to capture a wider range of potential market dislocations and ensure that banks are adequately capitalized against multiple, severe market-driven adverse events. For example, one shock might focus on a sharp repricing of credit assets, while another might simulate a sudden collapse in equity markets, forcing banks to withstand simultaneous or different types of extreme market movements. This enhanced rigor acknowledges the complex and interconnected nature of global financial markets and the potential for diverse shock mechanisms.

Fostering Stability in Capital Requirements: The Second Final Rule

The second finalized rule addresses a persistent concern within the banking industry: the year-over-year volatility in stress test-related capital requirements, specifically the Stress Capital Buffer (SCB). The SCB is a critical component of a bank’s total capital requirement, representing the capital needed to absorb losses during a severe economic downturn as projected by the supervisory stress test. Historically, the SCB could fluctuate significantly from one year to the next due to changes in economic scenarios, model updates, or shifts in a bank’s portfolio composition. Such volatility could complicate banks’ capital planning and allocation strategies, potentially leading to inefficient capital deployment or sudden, unexpected capital raises.

To mitigate this, the new rule mandates that when calculating a firm’s SCB requirement, the Board will average the results from the two most recent annual supervisory stress tests. This averaging mechanism is a direct response to industry calls for greater predictability. By smoothing out annual fluctuations, the rule is projected to reduce year-over-year volatility in capital requirements by approximately 50 percent, according to the Federal Reserve’s own analysis. This increased stability is expected to facilitate more effective capital management by banks, allowing for more strategic long-term planning regarding dividends, share buybacks, and lending capacity.

The implementation of this averaging mechanism will commence in 2028. This deliberate delay ensures that only stress test results derived from models that have incorporated the newly established annual public input process are used in the calculation. This staggered rollout underscores the Board’s commitment to ensuring that enhanced transparency and public accountability precede any changes that directly impact capital requirements, thereby building confidence in the new, more predictable framework. For banks, this means their 2028 SCB will be based on an average of their 2027 and 2026 stress test results, assuming both years utilized the publicly vetted models.

A Forward-Looking Proposal: Refining Noninterest Income Assessment

In addition to the two finalized rules, the Federal Reserve Board has issued a proposal for public comment concerning a revision to its noninterest income model. This model is crucial for projecting how banks’ fee-based revenues, which constitute a significant portion of many institutions’ earnings, would perform under stress conditions. The current model, while effective, may not fully capture the nuanced differences in business models across various firms that generate fee income. For instance, a bank heavily reliant on investment banking advisory fees might experience a different stress profile than one focused on asset management fees or retail service charges.

The proposed adjustments aim to enhance the stress test’s ability to capture this critical business model diversity. If adopted, these revisions would replace the existing noninterest income model with one that provides a more granular and accurate projection of each bank’s fee income under stress scenarios. This could involve segmenting noninterest income into more specific categories, applying different stress sensitivities to each category, or incorporating firm-specific characteristics that drive fee generation. The goal is to ensure that the stress test accurately assesses the resilience of a bank’s entire revenue stream, including its often-volatile noninterest components. Comments on this proposal are due 60 days after its publication in the Federal Register, inviting valuable feedback from the financial industry and other stakeholders on how best to refine this aspect of the stress test.

Official Commentary and Industry Reception

Vice Chair for Supervision Michelle W. Bowman reiterated the critical role of stress tests in the regulatory capital framework. "The stress test is an essential component of our regulatory capital framework," said Bowman. "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 statement emphasizes the dual objectives of these reforms: maintaining the robustness of the tests while making their mechanics more comprehensible and their outcomes more predictable.

Initial reactions from various corners of the financial industry are largely anticipated to be positive, particularly concerning the increased transparency and reduced volatility. Industry groups, such as the American Bankers Association and the Bank Policy Institute, have long advocated for greater clarity and stability in capital requirements. A spokesperson for a major banking association, speaking anonymously ahead of formal statements, indicated that "the move towards averaging SCB results and inviting public input on scenarios is a welcome development that will significantly improve banks’ ability to plan and deploy capital efficiently, without compromising safety and soundness." Financial analysts are also likely to view the changes favorably, as increased predictability in capital requirements can reduce uncertainty for investors and potentially lead to more stable bank valuations. However, some analysts might still express concerns about the overall stringency of the tests, especially for certain institutions, even with reduced volatility. Consumer advocacy groups, while generally supportive of strong bank regulation, will likely emphasize the importance of ensuring that increased transparency does not lead to a weakening of supervisory oversight.

Broader Economic and Systemic Implications

The cumulative effect of these finalized rules and the new proposal is not expected to materially alter aggregate capital requirements across the banking system. Instead, the primary impact is projected to be a more stable and predictable regulatory environment for the approximately 30-35 large financial institutions subject to these tests. By reducing the year-over-year variability in SCB requirements by roughly 50 percent, banks can engage in more effective long-term capital planning. This predictability can translate into more consistent lending to households and businesses, fostering greater economic stability by mitigating sudden shifts in credit availability.

From a broader financial stability perspective, these changes reinforce the integrity of the post-crisis regulatory framework. By making the stress test process more transparent and accountable, the Federal Reserve is not only addressing industry concerns but also strengthening public trust in the financial system’s resilience. The continuous refinement of models, particularly the proposed enhancements to the noninterest income model, signals an ongoing commitment to a risk-sensitive approach that adapts to the evolving complexities of financial services. As global financial markets continue to integrate, the United States’ robust and transparent stress testing regime will also serve as a benchmark for international regulatory standards, contributing to a more resilient global financial architecture. The Federal Reserve’s actions today mark a significant step forward in balancing regulatory rigor with operational predictability, ultimately aiming for a financial system that is both strong and adaptable.
