Key Takeaways
- U.S. banks could unlock $2.5 trillion of additional asset capacity through deregulation, lifting return on tangible common equity (ROTCE) by roughly 6 %.
- Deregulation is estimated to free 160 basis points of Common Equity Tier 1 (CET1) capital and 113 basis points of leverage relief for U.S. institutions.
- U.K. banks may gain about $400 billion of extra asset capacity if regulators grant 75 basis points of CET1 relief, with further leverage‑and‑buffer reforms under discussion.
- EU banks face higher capital demands under Capital Requirements Regulation 3 (CRR3), with CET1 requirements projected to rise by 109 basis points.
- Switzerland is weighing reforms that could increase CET1 for its sole Global Systemically Important Bank (G‑SIB) by up to 350 basis points.
- The widening regulatory divergence is already influencing profitability, market share, and valuations, giving U.S. banks a competitive edge while Europe emphasizes resilience.
- U.S. federal regulators’ March call for comments on streamlining capital rules aims to expand lending capacity and give banks “more runway” to serve communities and customers.
Overview of Alvarez & Marsal’s Findings
Alvarez & Marsal’s May 2024 Bank Deregulation Primer highlights a stark split in global banking regulation: the United States and the United Kingdom are moving toward lighter capital rules, thereby freeing substantial asset capacity, whereas the European Union and Switzerland are tightening requirements. The report quantifies the potential gains and losses, tying them to specific changes in CET1 and leverage metrics, and notes that the divergent paths are already showing up in banks’ financial performance and market positioning.
U.S. Deregulation Unlocks Massive Asset Capacity
According to the primer, U.S. banks could gain $2.5 trillion in additional asset capacity if current deregulatory proposals are fully implemented. This expansion would support an estimated 6 % uplift in return on tangible common equity (ROTCE), a key profitability indicator. The figure reflects the cumulative effect of releasing capital that is currently tied up in regulatory buffers, allowing banks to redeploy those funds into growth‑oriented activities.
CET1 and Leverage Relief Details for U.S. Banks
The report breaks down the capital relief into two components: 160 basis points of CET1 capital and 113 basis points of leverage relief. CET1 represents the highest‑quality capital that absorbs losses, while leverage relief reduces the ratio of total assets to Tier 1 capital, permitting larger balance sheets without breaching regulatory limits. Together, these measures provide the firepower behind the projected $2.5 trillion asset increase and the associated ROCE boost.
U.K. Banks Set to Benefit from CET1 Relief
In the United Kingdom, Alvarez & Marsal estimates that a 75 basis‑point CET1 relief would translate into roughly $400 billion of extra asset capacity for UK banks. The Bank of England’s competitiveness agenda is also reviewing potential adjustments to leverage ratios and buffers, which could further amplify the capacity gains. The report notes that UK regulators appear poised to follow a path similar to the U.S., albeit on a smaller scale.
EU Banks Confront Higher Capital Requirements
Contrasting with the Anglo‑American trend, the European Union is moving toward stricter capital rules under Capital Requirements Regulation 3 (CRR3). Alvarez & Marsal projects that EU banks will see their CET1 requirements rise by 109 basis points. This increase reflects the EU’s focus on bolstering financial resilience after the stress tests of recent years, but it also constrains the amount of assets banks can support relative to their capital base.
Switzerland’s Consideration of Steep CET1 Hikes for G‑SIB
Switzerland is evaluating reforms that could raise CET1 requirements for its only Global Systemically Important Bank (G‑SIB) by as much as 350 basis points. Such a move would markedly increase the capital buffer that the Swiss G‑SIB must hold, potentially limiting its ability to expand lending or pursue acquisitions. The proposal underscores Switzerland’s commitment to maintaining a robust safety net for its systemically important institution, even at the cost of reduced asset capacity.
Regulatory Divergence Already Shaping Outcomes
Fernando de la Mora, co‑head of Alvarez & Marsal’s EMEA Financial Services practice, warned that the divergence between regulatory regimes is becoming “increasingly visible in profitability, market share and valuations.” He observed that U.S. banks are benefiting from lower capital requirements more quickly than anticipated, allowing them to deploy capital into lending, acquisitions, shareholder returns, and technology. Meanwhile, European banks remain focused on resilience, which, while prudent, may constrain their competitive agility in the near term.
U.S. Federal Regulators’ Call for Comment
In March, U.S. federal bank regulators issued a request for comment on three proposals designed to streamline capital requirements for banks of all sizes. Comptroller of the Currency Jonathan V. Gould emphasized that the changes would “increase lending capacity and give banks more runway to support their communities and customers.” This initiative aligns with the broader deregulatory trend highlighted in the Alvarez & Marsal report and suggests that policymakers are actively seeking to balance safety with economic dynamism.
Implications for Global Banking Landscape
The contrasting regulatory trajectories portend a reshaping of the global banking hierarchy. U.S. and U.K. banks, buoyed by additional capital flexibility, may accelerate market share gains, pursue strategic acquisitions, and invest more heavily in digital transformation. EU and Swiss banks, facing higher CET1 demands, could see slower balance‑sheet growth, potentially ceding ground in certain business lines while bolstering loss‑absorbing capacity. Investors and analysts will likely monitor these developments closely, as the interplay between regulatory relief and stringency will influence banks’ profitability metrics, valuation multiples, and long‑term strategic options. The ongoing dialogue between regulators and the industry will be crucial in determining whether the current divergence narrows or widens over the coming years.
