The Bank of England published its policy statement and draft Code of Practice for sterling-denominated systemic stablecoin issuers on Monday, 22 June 2026, dropping the per-user holding limits that had drawn sharp criticism from industry since a November 2025 consultation. In their place, the BoE has set a £40 billion aggregate issuance guardrail per stablecoin, a temporary measure the Bank says it will remove once risks to credit provision are judged to have diminished. Regulated sterling stablecoins could begin operating in the UK as early as 2027.

What Changed and Why It Matters

The November 2025 consultation had proposed capping individual holdings at £20,000 per person and £10 million per business. Those limits would have constrained the total circulating supply of any stablecoin in the real economy. The replacement mechanism, a £40 billion issuance guardrail applied at the issuer level rather than the user level, gives individual users and businesses unconstrained access while the Bank retains a macro-level brake.

The reserve rules were also revised. Issuers may now hold up to 70% of backing assets in short-term UK government debt, up from 60% in the earlier proposal. The remainder must sit as unremunerated deposits at the Bank of England, earning no yield. A further concession applies to new-to-market issuers: firms designated as systemic at launch, or transitioning from the Financial Conduct Authority's non-systemic regime, may hold up to 95% of reserves in UK government debt during their scale-up phase.

The gap between BoE requirements and global peers remains significant. Circle's USDC model holds roughly 88% of reserves in yield-bearing assets. Under the BoE's revised rules, a mature sterling stablecoin issuer would be limited to 70%. Andres Monty, CEO of sterling stablecoin platform Range, had calculated that the original 40% unremunerated reserve floor would cost issuers approximately £11.2 million per year for every £1 billion in circulation, making UK issuance economically unviable relative to competitors. That figure reflects the superseded proposal; under the revised rules, which reduce the unremunerated deposit floor to 30%, the annual cost burden per £1 billion in circulation is meaningfully lower.

The BoE's regime is not limited to GBP-native products. The Bank has also made provision for non-sterling denominated systemic stablecoins such as USDC or USDT, should their use become widespread in the UK, signalling that existing dollar stablecoin operators may also fall within scope of the framework.

Political and Industry Pressure Shaped the Outcome

The policy shift did not happen in a vacuum. The UK House of Lords Financial Services Regulation Committee released a report in early June 2026, titled "Stablecoins: Waiting for Regulation," that warned the BoE's original backing rules "could have a significant impact on the business viability of stablecoin issuers in the UK" and urged the Bank to adopt a monitoring-first approach before imposing hard limits.

Industry voices were equally pointed. Katie Haries, Head of Policy for Europe at Coinbase, warned that holding caps represented "a cap on innovation, with real and significant risks."

The Bank acknowledged the criticism. Deputy Governor Sarah Breeden, who also called the new rules "a major milestone in delivering greater choice and innovation in UK payments," had previously conceded that the original reserve floor proposals may have been "overly conservative."

In parallel, the passage of the US GENIUS Act, a stablecoin framework signed by President Trump, intensified pressure on UK policymakers to remain competitive. BoE Governor Andrew Bailey, who also chairs the Financial Stability Board (FSB), has pushed back on the US approach, warning that dollar-pegged tokens without direct redemption "could undermine monetary sovereignty" and signalling an expected conflict with Washington over international stablecoin standards. Bailey's FSB chairmanship means his warnings carry weight at the international regulatory level, not only within the UK.

What This Means for Africa and South Asia

The practical stakes of a viable sterling stablecoin extend well beyond London.

Stablecoins already account for 43% of all crypto transaction volume in Sub-Saharan Africa, according to Chainalysis and Transak data covering July 2024 to June 2025. Nigeria alone absorbed $59 billion in stablecoin inflows over the same period, roughly 60% of the regional total, according to IMF and Naija247News data. Almost all of that volume moves through USD-denominated tokens such as USDT and USDC. The UK–Nigeria, UK–Ghana, and UK–Kenya corridors are among the busiest remittance routes into the region. A regulated GBP stablecoin would remove the double conversion cost of GBP to USD to local currency that is currently embedded in most stablecoin remittance products. Traditional wire transfer costs in Sub-Saharan Africa average 8.8% of transfer value (World Bank), compared to 1.5 to 2.5% via stablecoin rails.

Two parallel developments add further regional context. A UK–Nigeria corridor pilot linking the eNaira and SWIFT infrastructure is targeting launch in Q3 2026, illustrating the broader payments integration dynamic in one of the UK's busiest remittance corridors. Nigeria has also enacted the Investment and Securities Act 2025, which brings virtual assets under the Securities and Exchange Commission and creates a dual-track regulatory environment alongside the BoE/FCA framework. The interoperability question between these two regimes remains unresolved and is directly relevant to cross-border stablecoin settlement in the UK–Nigeria corridor.

The picture is similar for South Asia. India receives approximately $138 billion in annual remittances, the highest of any country in the world, and the UK is the primary source country for inward remittances from the British South Asian diaspora to India, Pakistan, and Bangladesh. Those corridors are today almost entirely served by USD stablecoin infrastructure. For fintech developers in India and Pakistan building remittance or payroll products targeting UK senders, services such as those offered by Razorpay, Cashfree, and BharatPe-adjacent platforms, the 2027 BoE regime launch creates a defined window to build compliant on and off-ramp integrations. The BoE's explicit reference to "programmable functionality capabilities" as a supported use case signals that developer-layer infrastructure is within scope. Developers building toward this market should note, however, that India's crypto tax environment and the Reserve Bank of India's posture toward private digital assets remain cautious, even as the RBI has shown greater openness to cross-border CBDC pilots. Regulatory headwinds on the destination end are a real constraint that product timelines must account for.

The scale constraint is worth noting. A £40 billion issuance guardrail, even if temporary, leaves sterling stablecoins far below the multi-trillion-dollar scale of USD stablecoin markets. That gap may limit how quickly GBP rails can compete with dollar-denominated alternatives in high-volume remittance corridors.

Timeline

The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 was signed into law on 4 February 2026, establishing the legal foundation for the entire BoE/FCA regime. The consultation window closes 22 September 2026. The FCA has already selected four firms for a regulatory sandbox covering payments, wholesale settlement, and crypto trading use cases. Firms seeking authorisation should note that the FCA application window runs from 30 September 2026 to 28 February 2027. The BoE expects to begin accepting systemic stablecoin issuer applications by year-end 2026, according to Sasha Mills, BoE Executive Director for Financial Market Infrastructure. Full enforcement is scheduled for 25 October 2027.
