Bank of England Sterling Stablecoin Regulation 2026: UK Framework Explained vs US GENIUS Act & EU MiCA

BoE vs Genius vs MiCA

The Bank of England published its UK framework and draft Code of Practice for systemic sterling stablecoins. With the US GENIUS Act and the EU’s MiCA already in place, the UK has now joined the trio of major regulatory regimes shaping the future of stablecoins. Three frameworks. Three different approaches. One growing headache for global treasuries.

This post breaks down what the BoE just released in London — and why it matters for payments professionals, fintech operators, CFOs, and treasury teams even if you never touch a pound sterling.

What Just Happened - the UK Framework

On June 22, 2026, the Bank of England released two key documents:

1. A policy statement responding to its November 2025 consultation (which received 86 industry responses).

2. A draft Code of Practice — the operational rulebook for issuers.

The legal foundation comes from the Financial Services and Markets Act 2023, which expanded the BoE’s remit under the Banking Act 2009 to cover “digital settlement assets,” including systemic stablecoins.

The UK’s two-part regime:

• The FCA regulates issuance, custody, and trading of all UK-issued qualifying stablecoins.

• The Bank of England + FCA jointly regulate “systemic” stablecoins (those designated by HM Treasury as large enough to pose risks to UK financial stability).

No stablecoin has been designated systemic yet. This framework is the rulebook waiting for the first major player.

The Big Reversal: Holding Limits Scrapped

The most significant change is the complete removal of individual and business holding caps. The November 2025 proposal included limits of £20,000 per individual and £10 million per business (per coin). After industry pushback and input from the House of Lords Financial Services Regulation Committee, these limits were eliminated.

Replaced by: A temporary £40 billion issuance guardrail per systemic stablecoin product (not per holder). The BoE will regularly review and intends to remove it once risks to credit provision are sufficiently mitigated.

This change makes a commercially viable sterling stablecoin business model possible in the UK.

Backing Assets: The New Reserve Rules

The BoE updated its reserve requirements:

• New standard: 70% in short-term UK government debt (up to 6-month maturity) + 30% in unremunerated central bank deposits.

• Previous proposal: 60% gilts / 40% BoE deposits.

At the £40 billion issuance guardrail, this 10-percentage-point shift frees up roughly £4 billion for income-generating assets — a meaningful improvement in unit economics.

Special provisions: Issuers recognized as systemic at launch can initially hold up to 95% in UK government debt, stepping down to standard ratios as they scale.

Prohibitions:

• Commercial bank deposits are not permitted as reserve assets.

• Issuers cannot pay interest or yield directly to stablecoin holders (consistent with MiCA and the GENIUS Act).

Redemption & Safeguarding: Strong Consumer Protections

• Redemption: Issuers must reimburse holders at face value within 24 hours on demand.

• Safeguarding: A two-trust model creates a structural firewall against issuer failure.

• Backing: Strict 1:1 reserve requirement.

• Liquidity management: Issuers may use repo/reverse-repo facilities during stress, but direct yield to holders remains prohibited.

These rules address key risks, such as gilt settlement on a T+1 cycle during rapid redemption spikes. A new central bank liquidity facility is planned for 2027.

Global Comparison: US, EU, and UK Frameworks

Jurisdiction	Framework	Key Reserve Rules	Yield to Holders	Timeline
United States	GENIUS Act (July 2025)	Federal (OCC/Fed/FDIC)	Prohibited	Implementing rules due July 2026
European Union	MiCA (in force since 2024)	60% in EU banks	Restricted	Transitional period ends July 1, 2026
United Kingdom	BoE/FCA Two-Part Regime	70% gilts / 30% BoE deposits	Prohibited	Targeting live markets in 2027

The UK is the slowest mover among the three, creating the need for multinational treasury teams to maintain three separate compliance maps for the same asset class.

Why Sterling Stablecoins Have Lagged

Global stablecoin market: ~$315 billion (early 2026). Sterling-denominated share: ~0.5%.

By comparison, USDC alone had a market value near $73.8 billion and traded over $19 billion in 24-hour volume as of late June 2026.

The BoE explicitly framed this as a “competitiveness move” to build a market that barely exists, in direct competition with dominant dollar stablecoins. Deputy Governor Sarah Breeden’s May 19, 2026 speech laid the groundwork for this policy shift.

Implications for Non-UK Firms

Overseas issuers of sterling-denominated systemic stablecoins must establish a UK subsidiary — passporting is not allowed.

The FCA-only regime applies to non-systemic sterling stablecoins, with a coordinated transition pathway to joint regulation as issuers scale. A forthcoming joint BoE/FCA paper will detail end-to-end operations.

What’s Coming Next: The Sterling Stablecoin Calendar

• Imminent: Joint BoE + FCA publication on regime operation and transition pathway.

• September 22, 2026: Consultation on the draft Code of Practice closes.

• End of 2026: BoE intends to finalize the Code for systemic issuers.

• 2027: Further consultations on updates, supervisory policy, and central bank liquidity facility.

• 2027: Target launch window for regulated sterling stablecoins (subject to HM Treasury systemic designation).

Action Plan for Payments & Treasury Teams

For CFOs & Treasury Teams:

• Track the upcoming joint BoE/FCA regime paper for onboarding criteria.

• Plan around USDC-class assets for near-term GBP-adjacent needs; don’t expect live sterling products before 2027.

• Build a three-region compliance map (US, EU, UK).

For Fintech Operators & Issuers:

• The £40B guardrail removes the biggest commercial barrier — sterling models are now viable.

• Non-UK issuers: Begin UK subsidiarization planning immediately.

• Submit feedback by September 22, 2026.

For Payments Executives:

• The UK is racing to close its gap. Watch for further competitive adjustments before year-end finalization.

• Model sterling assumptions conservatively given its current 0.5% global share.

Three jurisdictions. Three rulebooks. One global treasury function navigating the differences.

The arrival of the Bank of England’s sterling stablecoin framework completes the regulatory trifecta alongside the US GENIUS Act and EU MiCA, marking a pivotal moment in the institutionalization of digital money. While each regime reflects its jurisdiction’s priorities—stability, competitiveness, and consumer protection—the result is a fragmented global landscape that demands sophisticated, multi-jurisdictional compliance strategies from treasury teams, fintech issuers, and payments executives alike. With the UK’s deliberate push to close its market gap through pragmatic adjustments like the removal of holding limits and a viable £40 billion issuance guardrail, sterling stablecoins now have a genuine shot at scaling.

Yet until live products emerge in 2027, the near-term reality remains dollar dominance. In an increasingly tokenized world, staying ahead means mapping all three rulebooks, modeling conservative assumptions, and preparing now for the cross-border realities that will define the next chapter of payments infrastructure.
