UK stablecoin cap plan draws industry backlash

TLDR

The UK is facing criticism from crypto leaders over a Bank of England plan to cap how much stablecoin individuals and businesses can hold.

1. The draft regime would cap holdings of systemic stablecoins at roughly 20,000 per person and 10 million per business, alongside tight reserve rules.
2. Coinbase and other industry voices argue the caps would stifle innovation, weaken Londons digital?asset ambitions, and push activity to friendlier jurisdictions.
3. Key signals to watch are whether a fast?growing petition forces a parliamentary debate and whether final rules in 202627 soften the caps or keep them strict.

Deep Dive

1. What The Cap Plan Does

The Bank of Englands draft framework for systemic payment stablecoins proposes hard ceilings on user balances, aimed at the early adoption phase. Reports describe individual caps in the 5,00020,000 range and business caps between 1 million and 10 million per stablecoin, with the upper bounds of 20,000 and 10 million highlighted in several analyses.

The proposals also include a requirement that issuers keep about 40% of reserves in non?interest?bearing accounts at the central bank, significantly reducing their ability to earn yield on backing assets. These measures are framed as temporary safeguards to limit bank deposit flight and reduce the risk that a loss of confidence in a major stablecoin destabilizes the wider financial system, as explained in coverage of the sandbox and caps together.

2. Why Industry Is Pushing Back

Industry reaction has been sharply critical. Coinbase CEO Brian Armstrong has called the caps an innovation blocker, warning that limits of about 20,000 for individuals and 10 million for businesses, plus the 40% reserve lockup, would make the UK less competitive versus the over $180 billion global stablecoin market. His comments are quoted across several reports, including detailed pieces on his X posts and the draft.

A Stand With Crypto UK petition urging a more pro?innovation regime and a dedicated crypto czar has gathered more than 80,000 signatures and is approaching the 100,000 threshold that can trigger a parliamentary debate. Some UK MPs and industry executives echo concerns that strict caps and high reserve burdens could drive issuers and talent to places like the EU, Hong Kong, or the US, which already have frameworks such as MiCA and the GENIUS Act.

3. What To Watch Next

Regulators are pairing the cap proposal with a stablecoin sandbox, where firms like Revolut and several fintechs will test pound?pegged tokens for payments, settlement, and trading under FCA supervision. Findings from this sandbox are expected to inform final UK rules later in 2026, with full regimes coming into force around 2027.

Short term, the main catalysts are:

1. Whether the petition crosses 100,000 signatures and forces a public debate on the caps.
2. How much flexibility the BoE and FCA show in revising holding limits and reserve requirements after sandbox data.
3. How aggressively rival jurisdictions court stablecoin issuers while the UK remains cautious.

Confidence: high because multiple independent policy and industry reports describe the same caps, rationale, and backlash.

Conclusion

The controversy reflects a classic trade?off: UK regulators want to contain systemic risk from large stablecoin balances, while crypto firms want scale and economics that support mass adoption. If London keeps strict caps and heavy reserve rules, stablecoin use in the UK will likely grow slowly and remain relatively constrained, with more aggressive innovation happening in other regulatory hubs. If the sandbox and political pressure lead to more flexible limits, the UK could still pivot toward a more competitive, but still tightly supervised, stablecoin ecosystem.
