Banking Regulation in the United Kingdom, France and the European Union (2007–2026)

Executive Summary

This short article summarises the academic paper published on the link above which examines the evolution of banking regulation in the United Kingdom, France and the European Union between 2007 and 2026, analysing how successive financial and geopolitical crises have shaped the modern prudential regulatory framework. The paper considers the development and implementation of the Basel Accords, the operation of the European Banking Union and the differing supervisory and legal approaches adopted within the three jurisdictions.

The paper is organised around five defining events: the Global Financial Crisis and United States sub-prime mortgage collapse; the failure of Northern Rock; the Greek sovereign debt crisis; the COVID-19 pandemic; and the geopolitical disruption arising from the war in Ukraine and wider international tensions. Each crisis is examined to identify the weaknesses exposed within the prevailing regulatory framework, the legislative and supervisory reforms introduced in response and the extent to which those reforms have enhanced financial stability.

The analysis in the paper demonstrates that the Basel framework has evolved from a relatively simple capital adequacy regime into a comprehensive prudential system encompassing capital quality, leverage, liquidity, operational resilience, supervisory review and macro-prudential oversight. Particular emphasis is placed upon Basel III and its finalisation (Basel 3.1), including the introduction of stronger capital requirements, the Liquidity Coverage Ratio, the Net Stable Funding Ratio, leverage constraints and measures designed to address systemic risk.

A principal theme of the paper is the distinction between liquidity and solvency risk. The collapse of Northern Rock demonstrated that a bank may satisfy regulatory capital requirements yet nevertheless fail because of an inability to obtain funding. That experience fundamentally altered prudential regulation by establishing liquidity as a central pillar of banking supervision alongside capital adequacy.

The paper further considers the Eurozone sovereign debt crisis and the structural relationship between sovereign indebtedness and banking stability. It concludes that the Greek crisis exposed limitations not only within the Basel framework but also within the constitutional architecture of the European Monetary Union. Although Banking Union, the Single Supervisory Mechanism and the Single Resolution Mechanism have materially strengthened the resilience of European banks, the bank–sovereign nexus remains an important unresolved structural issue.

The response to the COVID-19 pandemic provides a practical assessment of the effectiveness of the post-2008 reforms. Unlike the Global Financial Crisis, banks generally entered the pandemic with significantly stronger capital and liquidity positions, enabling them to absorb rather than amplify macroeconomic stress. Nevertheless, the paper concludes that the successful management of the crisis depended not only upon prudential regulation but also upon unprecedented fiscal intervention and central bank liquidity support.

The paper also considers more recent geopolitical developments and argues that modern threats to financial stability increasingly arise from sources lying outside the traditional scope of banking regulation. Energy market disruption, sanctions regimes, cyber risk, operational resilience and global dollar liquidity have become increasingly important determinants of banking stability. These developments illustrate that while prudential regulation remains essential, many contemporary risks cannot be addressed solely through capital and liquidity requirements.

A comparative analysis of the United Kingdom, France and the European Union highlights significant institutional differences despite substantial convergence in substantive prudential standards. Following Brexit, the United Kingdom has retained close alignment with international Basel standards through the PRA's Basel 3.1 reforms while acquiring greater regulatory autonomy. France continues to operate within the European Banking Union through a rules-based civil law framework characterised by the supervisory roles of the ACPR, the ECB and the European Banking Authority. The paper also explores how differing legal traditions influence supervisory practice, statutory interpretation and judicial review.

The central conclusion is that the Basel reforms have been highly successful in strengthening the resilience of conventional banking institutions against the principal causes of the 2007–2009 financial crisis. Banks are now substantially better capitalised, maintain stronger liquidity positions and are subject to more intensive supervision than at any previous time.

However, the paper concludes that prudential regulation has necessarily remained reactive, with each generation of reforms addressing weaknesses revealed by previous crises while leaving new vulnerabilities to emerge. The most significant future challenges are likely to arise not from traditional balance-sheet risks but from sovereign debt, geopolitical instability, cyber threats, operational resilience, artificial intelligence, digital finance and other technological developments. Ensuring financial stability will therefore require continued evolution of the regulatory framework, together with close coordination between prudential regulators, governments and central banks.

Accordingly, the paper concludes that while Basel III represents a substantial achievement in international prudential regulation, the future of banking regulation will increasingly depend upon its ability to respond to risks originating beyond the traditional perimeter of banking law itself.

The paper will be of interest to banks, financial institutions, regulators, governments, academics and legal practitioners concerned with banking regulation, prudential supervision, financial stability and comparative financial services law.
