The Bank of England is planning to loosen capital requirements for major UK lenders to inject additional liquidity, help banks sustain lending, and support financial markets during periods of stress, while bringing UK requirements more closely into line with international standards. These proposals come as regulators face growing pressure to do more to stimulate economic growth. However, the move also raises concerns about credit quality and financial stability, as relaxed requirements could encourage banks to lend to weaker borrowers and contribute to higher leverage and risk-taking in financial markets.
Capital requirements determine how much capital banks must hold against their assets to absorb potential losses and maintain resilience during periods of stress. Easing these requirements allows banks to deploy more capital towards lending, supporting credit availability and market functioning when financial conditions deteriorate. The proposal also follows a relaxation of US leverage requirements in November 2025, increasing competitive pressure on British lenders operating in global markets.
UK economic growth has remained subdued amid geopolitical uncertainty, which has pushed up commodity prices, added to inflationary pressures, and weakened consumer confidence. By improving banks’ capacity to lend, the Bank of England aims to support economic activity and help restore confidence among households and businesses.
Financial stability and market risk concerns
At the same time, the proposals heighten concerns about financial stability and market risk. Easier credit conditions could increase lending to highly leveraged investors, including hedge funds that use significant borrowing to purchase equities. A substantial share of this debt-fuelled activity has been concentrated in AI-related stocks, despite uncertainty over whether many AI investments will generate the expected returns. If AI projects fail to deliver, firms may struggle to service their debts, potentially increasing banks’ non-performing assets and weakening overall credit quality.
The Financial Policy Committee has also flagged risks arising directly from rapid advances in frontier AI, which have progressed faster than many experts expected. While these systems could improve productivity, they may also materially increase cyber and operational risks by enabling malicious actors to cause disruption at lower cost and greater scale. Such shocks could affect banks and other systemically important financial institutions, with broader implications for the resilience of the financial system.
In addition, the recent surge in AI-related equities in markets such as the US and South Korea has been accompanied by increased leveraged investing. Similar dynamics could emerge in the UK if investors attempt to participate in the rally, increasing risk appetite and leverage across the market.

This appears plausible given that 60.7% of investors cite achieving the highest possible return as their primary investment objective, according to GlobalData’s Investor Insights: Investment Driver Analytics 2025. Such conditions could amplify market volatility and pose wider systemic risks if valuations correct sharply or funding conditions tighten.
Overall, easing regulatory requirements could support lending and help the Bank of England deliver its mandate. However, these changes should be accompanied by targeted safeguards to discourage excessive risk-taking and weaker underwriting standards. A balanced approach would help boost liquidity and economic activity while managing the associated financial stability risks.
