US Regulators Retreat from Output Floors in Basel III Endgame
US banking regulators have significantly altered their approach to implementing the final components of the Basel III capital standards, abandoning the “output floors” that were previously a central tenet of the proposed rules. This shift, revealed in recent statements, marks a departure from internationally agreed-upon standards and reflects a recalibration of priorities within the Federal Reserve and other regulatory bodies.
The Basel III Endgame: A Recap
The Basel III endgame refers to the final set of reforms stemming from the Basel Committee on Banking Supervision’s post-crisis capital requirements, established in 2017. These reforms aim to limit the extent to which banks can use internal models to calculate capital requirements, ensuring these calculations don’t fall significantly below regulator-set standardized approaches. Risk.net provides a detailed timeline of the US rollout of these reforms.
Abandonment of Output Floors
The initial proposals included output floors, designed to prevent internal models from producing capital requirements that were too low. But, regulators have now moved away from this approach. According to Risk.net, this decision represents a significant change, as regulators previously “fought hard to include” these floors.
Rationale Behind the Shift
Michelle Bowman, the US Federal Reserve’s vice-chair of supervision, has articulated a rationale for this change, rejecting “blind adherence” to global standards. This suggests a desire for greater flexibility in tailoring regulations to the specific circumstances of the US banking system. Bowman has also described a “standardized approach” proposal intended to update risk-based capital requirements for most banks, separate from the Basel III endgame reproposal for the largest institutions. PwC highlights this broader effort to revise risk-based capital requirements.
Implications for Banks
The removal of output floors is expected to provide banks with greater flexibility in managing their capital requirements. Banks that rely heavily on internal models may benefit from this change, as they will have more leeway in determining their capital levels. However, the overall impact will depend on the specifics of the revised rules and how banks choose to respond.
Broader Context and Congressional Oversight
The Basel III endgame has been a long-running process, with significant debate and scrutiny from both the industry and Congress. The Congressional Research Service notes that 45 bank regulators worldwide collaborate through the Basel Committee on Banking Supervision to establish consistent bank capital requirements, though these frameworks have no direct legal force in the United States.
Looking Ahead
Michelle Bowman is scheduled to unveil the latest version of the rules on March 19, 2026. This re-proposal is expected to mark a critical juncture in the US implementation of the Basel III reforms. Market participants will be closely monitoring the details of the revised rules to assess their potential impact on the banking sector. The US rollout of the Basel Committee’s post-crisis capital reforms has been a long time coming, and this latest development signals a significant shift in approach.
