UK stablecoin caps face industry pushback

TLDR

UK regulators are proposing caps on stablecoin holdings, and major crypto players argue the limits could badly hurt the UKs digital asset ambitions.

1. The Bank of England proposes caps of roughly 5,00020,000 per person and 1 million10 million per business, plus strict reserve rules for UK-regulated stablecoins.
2. Coinbase and other industry voices say these caps would cripple real-world stablecoin use and push innovation to friendlier hubs like Hong Kong and the US.
3. Final UK rules are due in 202627, so consultations, petitions, and sandbox results will determine whether the caps soften or stay strict.

Deep Dive

1. What Caps Are Planned

The Bank of England (BoE) has outlined a framework for UK-regulated stablecoins used in payments, including caps on how much can be held. A BoE paper from November 2025 floated ranges of 5,000 to 20,000 for individuals and 1 million to 10 million for businesses, depending on risk and use case, to limit potential stress on banks and payment systems if funds rapidly move into stablecoins.

Separately, draft rules would also require issuers to park about 40% of reserves in non interest bearing central bank accounts, according to reporting on the proposal and industry reaction from Coinbase CEO Brian Armstrong. This is meant to ensure safety but reduces issuers ability to earn yield on backing assets.

2. Why Industry Objects

Industry leaders argue these caps are too low for serious commerce, effectively treating stablecoins as small retail tools rather than core payment or treasury infrastructure. Armstrong has warned that the proposed limits and reserve rules would stifle innovation and hurt the UKs competitiveness, with a public petition already above 80,000 signatures urging a pro innovation stance.

Critics also highlight the contrast with jurisdictions like Hong Kong, which is preparing its first stablecoin licenses with fewer hard caps and a more growth oriented posture.

3. What To Watch Next

The UKs Financial Conduct Authority (FCA) has picked four firms, including Revolut, to test stablecoin use in a regulatory sandbox, with findings feeding into final rules later in 2026 and a permanent regime slated for 2027. Industry pushback could still reshape details, especially cap levels and reserve composition.

Key signals to monitor are: whether the petition crosses 100,000 signatures (triggering a potential parliamentary debate), any revised BoE or Treasury consultations, and how sandbox results influence the final rulebook.

Conclusion

UK stablecoin caps are shaping up as a tug of war between financial stability concerns and the desire to be a global crypto hub. If policymakers keep conservative limits, sterling stablecoins may lag competitors built in jurisdictions that allow larger balances and more flexible reserves, while any softening of the caps could unlock a more meaningful role for London in the next phase of stablecoin adoption.
