America’s Regulatory Pivot Redraws the Global Banking Map

The United States is moving toward one of its most significant reversals of banking regulation since the financial crisis, led by Michelle Bowman, the Federal Reserve’s vice-chair of supervision. A former community banker from Kansas, Bowman has become the chief proponent of easing capital rules, softening supervisory standards and taking a more flexible approach to the final phase of the Basel III framework. Though she calls the effort ‘modernisation’ rather than deregulation, the shift would leave US banks operating with lighter constraints than at any point in the past decade.

Researchers estimate the changes could unlock trillions of dollars in lending and dealmaking capacity, boosting profitability and allowing large banks to expand more aggressively. Wall Street executives have welcomed the move, arguing that stringent post-2008 rules pushed lending and risk-taking into less regulated parts of the financial system, especially private credit markets. Many of the biggest institutions already hold excess capital and expect to channel it into loan growth, acquisitions and share buybacks. The push also aligns with the White House’s broader interest in supporting credit availability and economic expansion.

The shift has drawn warnings from regulators and credit analysts who fear the US may be repeating a familiar cycle of loosening rules during calm periods only to confront instability later. It has been just two years since the failures of Silicon Valley Bank, Signature Bank and First Republic exposed weaknesses in liquidity management, uninsured deposits and supervisory follow-through. Critics say that reducing capital buffers and relaxing stress-test pressures could again weaken the system’s resilience in the face of future shocks.

The ramifications extend far beyond the United States. Policymakers in Europe and the UK have delayed their own Basel III implementation while watching Washington’s moves, raising concerns about a widening gap in regulatory regimes. European banks, already constrained by higher capital requirements, warn they could become less competitive against US rivals operating under looser rules. Some executives have even floated the idea of shifting business or headquarters to America if the divergence widens. While British regulators appear somewhat open to easing leverage ratios, the European Central Bank has signalled that substantial capital reductions remain unlikely.

The growing divergence has revived fears of a regulatory race, with major financial centres potentially feeling pressure to lower standards to keep pace. Such competitive easing contributed to vulnerabilities in the years before the 2008 crisis. Supporters of the US approach insist that recalibrating certain post-crisis rules is both overdue and manageable, but the scale of the changes has intensified debate among global regulators.

As the United States dismantles parts of its post-crisis rulebook, the global financial landscape is being redrawn. Whether other jurisdictions follow Washington’s lead or maintain stricter regimes will shape competitiveness, capital flows and financial stability for years to come. The consequences of this shift, already evident in international policy discussions, are likely to extend well beyond America’s banking sector.
