The Bank of England is preparing to introduce a sweeping regulatory framework by 2026 that will significantly restrict how banks interact with cryptocurrencies, in line with global standards issued by the Basel Committee on Banking Supervision. According to David Bailey, Executive Director of Prudential Policy at the Bank of England, the approach will be “on the more restrictive end,” prioritizing financial stability over early market expansion.

The new rules are expected to place heavy constraints on the amount of exposure banks can have to digital assets, particularly volatile and unbacked cryptocurrencies like Bitcoin. Under the framework, financial institutions may be required to hold capital reserves equal to 1,250% of their crypto exposure—effectively limiting risky crypto-related activity on their balance sheets. This mirrors Basel’s global guidelines, which have been delayed to January 2026 to give jurisdictions time to implement necessary infrastructure.

“We're taking a cautious, data-driven approach. Banks will be asked to limit crypto exposure in the early phase while we continue to assess systemic risk,” said Bailey at a recent financial policy forum in London.

 

Conservative by Design

The UK’s move stands out for its conservatism. While other jurisdictions, such as Switzerland and the European Union, are expanding institutional access to tokenized assets and crypto-related services, UK regulators are focused first on robust oversight.

Bailey emphasized that the UK's prudential regulation will initially aim to minimize risk and uncertainty in the banking sector. “Exposure limits will reflect the volatility and opacity of these markets,” he said, underscoring that the framework may evolve if sufficient data supports loosening restrictions in the future.

Scope of Regulation

The rules will not only target banks’ direct crypto holdings but also impact crypto-linked activities such as custodial services, stablecoin interaction, and trading desk operations. The framework is expected to differentiate between unbacked crypto assets and those with underlying reserves, like tokenized deposits or fiat-backed stablecoins, allowing for more lenient treatment in the latter category.

The regulations will form part of the UK’s broader Financial Services and Markets Act reforms, and will be implemented in close collaboration with the Financial Conduct Authority (FCA) and Prudential Regulation Authority (PRA).

Global Influence and Domestic Tensions

The decision to align with Basel’s cautious stance reflects the UK’s desire to maintain international consistency while safeguarding its domestic financial system. However, industry players argue that the UK risks falling behind more innovation-friendly regions like the U.S. and the UAE, where banks are already exploring broader crypto use cases, including blockchain-based settlement systems and tokenized asset issuance.

In April, the FCA expanded access to crypto exchange-traded products (ETPs) for professional investors but stopped short of allowing retail investment in such vehicles—highlighting the UK's careful progression into crypto markets.

“There’s a real concern that if we overregulate now, we may miss out on the infrastructure that will power global finance in the next decade,” said a UK-based fintech lobbyist, requesting anonymity.

 

What Happens Next

Over the coming months, the Bank of England is expected to issue consultations and technical papers outlining capital treatment models, disclosure requirements, and risk-weighted asset categories for crypto exposure. The final rules will go into effect alongside the Basel Committee’s revised 2026 implementation deadline.

The UK’s upcoming crypto banking regulations signal a strong commitment to cautious adoption, prioritizing systemic resilience over rapid innovation. By taking a conservative stance now, the Bank of England aims to protect its financial institutions while preserving flexibility for future adaptation as the global digital asset ecosystem matures.
