US and UK Banks Gain $1.3 Trillion Edge from Deregulation

By VirentaNews Staff — May 26, 2026

Top banks in the United States and the United Kingdom are positioned to expand their balance sheets by an estimated $1.3 trillion, thanks to recent deregulatory moves that ease capital and liquidity requirements. While institutions in the European Union and Switzerland remain bound by stringent post-2008 financial safeguards, their Anglo-American counterparts are capitalizing on looser oversight to grow lending and investment portfolios. This divergence in regulatory philosophy, accelerated after the 2023 banking turmoil, marks a strategic shift in global finance. The outcome is a widening competitive gap that could reshape cross-border banking dynamics, affect international lending rates, and influence how financial stability is balanced against economic growth in the years ahead.

Regulatory Divergence Fuels Balance Sheet Expansion

Since 2023, financial regulators in the US and UK have rolled back key elements of post-crisis banking rules, arguing that streamlined requirements would enhance competitiveness and resilience. In the US, the Federal Reserve and other agencies revised the post-2008 Dodd-Frank Act framework, easing stress test thresholds and modifying the Supplementary Leverage Ratio (SLR) for globally systemically important banks (G-SIBs). Similarly, the UK’s Prudential Regulation Authority (PRA), post-Brexit, has pursued a more flexible approach to capital buffers, allowing banks like Barclays, HSBC, and Standard Chartered greater freedom to deploy capital. These changes enable banks to increase lending and trading activities without holding equivalent levels of high-quality liquid assets. As a result, analysts estimate that the top-tier institutions in both countries collectively gained room to expand their balance sheets by approximately $1.3 trillion—funds that can be used to support corporate loans, infrastructure financing, or capital markets operations, putting them at a structural advantage over peers in stricter jurisdictions.

The Path to Light-Touch Regulation

The current regulatory split traces back to the global financial crisis of 2007–2008, when excessive risk-taking and inadequate capital buffers led to massive bank failures and taxpayer-funded bailouts. In response, the Basel Committee on Banking Supervision introduced a series of international accords—Basel III and later Basel IV—that mandated higher capital ratios, liquidity coverage, and leverage limits. The EU and Switzerland adopted these rules with minimal deviation, embedding them into national frameworks like the EU’s Capital Requirements Directive (CRD V). However, the US began softening its stance after 2018, when Congress exempted mid-sized banks from certain stress testing mandates. The trend accelerated under the 2023 regulatory reset, following regional bank collapses that prompted debate over whether overregulation had hampered risk-adjusted lending. The UK, newly independent from EU oversight after Brexit, seized the opportunity to reposition itself as a more agile financial center. By aligning its rules less rigidly with Basel standards, it aimed to boost post-Brexit competitiveness—especially in investment banking and fintech—while maintaining systemic stability.

Key Players Shaping the Regulatory Shift

The push for deregulation has been championed by a coalition of financial institutions, policymakers, and industry lobbyists who argue that lighter rules enhance global competitiveness. In the US, major banks including JPMorgan Chase, Bank of America, and Citigroup have long advocated for recalibrating post-crisis rules, claiming they stifle innovation and cross-border lending. Their influence is evident in the Federal Reserve’s revised SLR framework, which now excludes certain central bank reserves from leverage calculations. In the UK, the Treasury and the PRA have worked closely with the City of London Corporation, a powerful financial district advocacy group, to design rules that support market growth. Figures like former Chancellor Rishi Sunak and current PRA head Sam Woods have publicly endorsed a “smarter regulation” approach, emphasizing efficiency over uniform stringency. Meanwhile, EU regulators such as the European Central Bank and the European Banking Authority have resisted similar moves, citing concerns about financial fragmentation and moral hazard, particularly in countries with weaker fiscal backstops.

Global Implications for Banks and Borrowers

The regulatory gap between Anglo-American and continental European banks is creating uneven playing fields in international finance. EU and Swiss institutions like UBS, BNP Paribas, and Deutsche Bank now face higher compliance costs and tighter constraints on balance sheet growth, potentially limiting their ability to compete in global markets. This could lead to a gradual shift in capital flows, with multinational corporations increasingly turning to US and UK banks for large loans and structured finance. For borrowers, the immediate effect may be improved access to credit in deregulated markets, though some economists warn this could fuel asset bubbles or increase systemic risk over time. Additionally, financial stability watchdogs, including the Bank for International Settlements, have expressed concern that fragmented regulatory standards could complicate cross-border crisis management and reduce transparency.

The Bigger Picture

This regulatory divergence reflects a broader philosophical split over how best to manage financial risk in a globalized economy. The US and UK are betting that flexible, principles-based oversight fosters innovation and economic resilience, while the EU and Switzerland prioritize precaution and harmonization. As climate stress tests, digital currencies, and AI-driven trading grow in importance, the question of how to regulate without stifling progress will only intensify. The current imbalance may also prompt retaliatory adjustments, such as EU-level incentives to strengthen its own banking union or bolster capital markets. Ultimately, the $1.3 trillion expansion window isn’t just about balance sheets—it’s a test of competing financial models in the 21st century.

What comes next will depend on both market performance and political will. If US and UK banks achieve stronger growth without triggering instability, pressure may mount on EU regulators to reconsider their stance. Conversely, any significant financial stumble in the deregulated bloc could reignite calls for tighter global standards. For now, the financial world watches closely as two regulatory regimes head in opposite directions—each claiming to safeguard stability, but defining it differently.
