Bank of England Considers Volume Guardrails as Alternative to Stablecoin Holding Limits

Regulatory Pivot in UK Stablecoin Framework

The Bank of England is examining temporary volume-based guardrails on stablecoin issuance as a potential replacement for individual and business holding limits. Deputy Governor Sarah Breeden outlined the thinking during remarks at City Week 2026, indicating the central bank is responding to concerns that strict ownership caps could hinder practical use cases and UK competitiveness.

The move represents a notable adjustment from earlier proposals that included a £20,000 limit for individuals and a £10 million cap for businesses on holdings of certain sterling stablecoins intended for everyday payments. Those restrictions drew criticism from fintech firms, traditional financial institutions, and crypto industry groups, who argued they were overly restrictive compared to approaches in other major jurisdictions.

Addressing Financial Stability Concerns

Central to the Bank of England's deliberations is the potential for rapid shifts from bank deposits into stablecoins during periods of stress, which could affect lending and overall financial stability. Officials have expressed worry about scenarios where large-scale deposit outflows might lead to credit tightening.

By focusing on overall issuance volumes rather than per-user holding restrictions, regulators believe they can manage systemic risks more efficiently. This method would impose fewer operational burdens on businesses that rely on stablecoins for transactions, payments, and liquidity management.

Broader Context of Tokenization and Digital Money

Breeden's comments also reinforced the Bank of England's support for tokenization in financial markets. She highlighted how tokenized assets and payments, including regulated stablecoins and tokenized bank deposits, could lower costs and increase competition while maintaining the central bank's role as the anchor of the monetary system through central bank money.

The central bank is simultaneously advancing plans to extend its core settlement infrastructure toward near 24/7 operations to better accommodate digital asset technologies and cross-border activity. This infrastructure upgrade aligns with growth in tokenization and related innovations.

Breeden emphasized that private-sector innovations in digital money are not seen as conflicting with the Bank's responsibilities. A future payment landscape could include traditional accounts alongside tokenized deposits, regulated stablecoins, and potentially a retail central bank digital currency, depending on evolving needs.

Industry Reactions and International Comparisons

Representatives from the crypto sector welcomed the reconsideration of holding limits but stressed the need for careful calibration. Coinbase's UK head of policy, Katie Harries, noted that an issuance cap might prove more workable than holding limits, though she highlighted that few other jurisdictions are imposing similar upfront restrictions on innovation.

Simon Jennings of the UK Cryptoasset Business Council described the exploration of alternatives as positive but advocated tying any interventions to actual supervisory data and risk metrics rather than broad caps applied from the start.

The discussion occurs against a backdrop of more permissive developments in the United States, where cryptocurrency-friendly policies have prompted the UK to evaluate its regulatory edge as a financial hub.

Implications for Banks and Stablecoin Issuers

Banks remain able to participate in stablecoin issuance, provided activities occur through separate non-deposit-taking entities with distinct branding. This structure helps maintain separation between core banking functions and digital asset activities.

The evolving approach seeks to balance innovation with prudence. Regulators continue engaging with industry stakeholders to refine rules that support the growth of digital payments and tokenized markets without compromising stability.

As the consultation process advances, market participants will watch closely for details on how volume guardrails might be structured, including thresholds, duration of temporary measures, and any exemptions that could apply to specific use cases or participants.

Outlook for UK Digital Assets Regulation

This development signals a pragmatic adjustment in the UK's regulatory stance on stablecoins. By listening to feedback and exploring less burdensome alternatives, the Bank of England aims to position the country as a competitive player in digital finance while upholding its core mandate to safeguard monetary and financial stability.

The final framework, expected later in 2026, will likely influence how quickly sterling stablecoins can scale for both retail and wholesale applications, with potential ripple effects across payments, securities settlement, and broader tokenization efforts in the UK market.
