The UK has unveiled its final crypto regulatory framework, easing several earlier proposals and cutting a key stablecoin issuer capital requirement by 50% after industry feedback that the original rules risked making Britain less competitive.
The Financial Conduct Authority said stablecoin issuers will be required to hold capital equal to 1% of the total value of stablecoins they issue, down from the 2% requirement previously proposed. The change is one of the most important concessions in the final rulebook, which will bring cryptoasset firms fully within the FCA’s regulatory perimeter for the first time when the regime takes effect in October 2027.
The framework covers how crypto firms trade, custody assets, serve consumers and manage operational and market risks. It also introduces capital requirements, stress-testing expectations and market-abuse rules designed to make crypto firms operate more like regulated financial services businesses. The FCA said the revisions were intended to create a proportionate system that protects consumers while allowing firms to compete internationally.
The stablecoin rules will mainly apply to sterling-denominated stablecoins supervised by the FCA. Stablecoins deemed systemic, particularly those with the potential to become widely used for payments, will fall under a tougher Bank of England regime. That dual structure reflects the UK’s view that crypto-trading stablecoins and payment-system stablecoins create different levels of financial-stability risk.
Stablecoin Rules Softened After Industry Pushback
The capital reduction from 2% to 1% signals that UK regulators are trying to balance prudence with market development. Stablecoin issuers had argued that the earlier requirement would make sterling stablecoins expensive to operate, especially when competing with U.S. dollar stablecoins that dominate global crypto liquidity.
The FCA also softened other parts of the proposal. It removed some public disclosure requirements, gave issuers more flexibility around customer redemptions in certain cases and adjusted exchange-specific rules to better reflect how crypto markets actually operate. Officials said the final rules were shaped by evidence and feedback from the industry.
The changes follow a broader softening in UK stablecoin policy. The Bank of England recently dropped proposed individual holding caps for systemic sterling stablecoins and shifted toward an issuance-limit model. It also eased backing-asset rules by allowing a larger share of reserves to be held in short-term UK government debt rather than zero-interest central bank deposits.
Regulatory Competition Shapes UK Strategy
The UK’s final framework comes as major financial centers compete to attract digital asset businesses. The European Union has already implemented MiCA, while the U.S. has moved toward a more crypto-friendly policy stance under the Trump administration. Against that backdrop, overly strict UK rules risked pushing firms toward other jurisdictions.
For stablecoin issuers, the 1% requirement still represents a meaningful cost. Smaller issuers may find it difficult to hold additional capital while also maintaining full backing assets, compliance systems and redemption infrastructure. However, the lower threshold is likely to be viewed as more workable than the earlier proposal.
For exchanges, custodians and brokers, the framework creates a clearer path to full authorization. Crypto companies will be able to begin applying for FCA authorization from September 30, 2026, ahead of the October 2027 effective date. That timeline gives firms more than a year to prepare systems, governance, capital planning and customer-protection controls.
The market impact could be significant. A clear regime may encourage banks, brokerages and fintechs to enter UK crypto markets, especially if stablecoin rules become commercially viable. At the same time, the FCA’s stricter supervision may raise costs for smaller platforms and push weaker operators out of the market.
The broader message is that Britain wants crypto activity inside the regulated financial system, not outside it. By cutting the stablecoin capital requirement while keeping custody, trading and risk-management rules in place, the UK is trying to position itself as both a serious regulator and a competitive digital asset hub.
