On May 19, at CityWeek 2026 in London, Bank of England Deputy Governor Sarah Breeden confirmed that the central bank is abandoning its proposed individual holding limits for sterling stablecoins, shifting instead toward aggregate issuance caps placed on token providers. The November 2025 consultation figures – £20,000 per individual, £10 million per business – are off the table.
This follows sustained pressure from the fintech sector, banking institutions, and parliamentary submissions that challenged both the practical enforceability of the original proposals and Britain’s positioning in a rapidly consolidating global digital finance race.
To understand the scale of this reversal, the original reasoning needs unpacking. The BoE’s own economic modeling showed that without individual holding limits, potential demand for emergency central bank lending during a severe market panic could reach £250 billion – compared to £112 billion if a £20,000 per-person cap were maintained. That is not a rounding error; it is the difference between a manageable liquidity event and a systemic crisis.
The scenario regulators feared is straightforward: large-scale migration of retail deposits from commercial bank accounts into digital tokens forces traditional banks to liquidate assets or cut lending to maintain their Liquidity Coverage Ratios. The downstream effect is a credit crunch with consequences for the real economy that extend well beyond anything happening on a blockchain.
Whatever its prudential logic, the individual wallet limit ran into an architectural wall. Stablecoin issuers do not maintain direct relationships with millions of end users. Tether, for instance, operates through only several hundred direct institutional counterparties – exchanges, market makers – who then handle distribution to hundreds of millions of retail users.
Imposing a £20,000 cap at the end-user wallet level, when the issuer interacts exclusively with a small number of large institutional endpoints, is a structural mismatch between the regulatory tool and the actual system it is trying to govern. Parliamentary evidence submitted by industry groups made exactly this point, and the BoE clearly absorbed it.
The BoE itself acknowledged that its original rules were “overly conservative,” which is an unusual admission for a central bank to make publicly. The context is hard to ignore. Following the Trump administration’s aggressive embrace of crypto assets, Britain found itself in a position of regulatory isolation at precisely the wrong moment.
Dollar-denominated stablecoins – led by Tether and USD Coin – dominate well over 90% of global stablecoin market capitalization, and viable sterling-backed alternatives are functionally absent. The practical consequence is that British workers receiving cross-border payments through digital wallets are defaulting to dollar-denominated instruments, reinforcing foreign currency infrastructure inside the domestic digital economy. Keeping the proposed caps in place would have accelerated that structural drift.
One detail consistently flattened in reporting on UK crypto regulation is that two entirely separate regulatory regimes are running in parallel. The Financial Conduct Authority governs smaller or non-systemic stablecoins used in crypto trading; firms can officially begin applying for FCA authorization from September 2026, with the full regulatory perimeter taking effect on October 25, 2027. The Bank of England only enters the picture when a sterling stablecoin scales to the point where its failure could threaten the broader financial system.
The problem is that nobody has clearly defined the transition mechanism between those two tiers. How an issuer moves from FCA oversight into the BoE’s far stricter systemic regime – without hitting a wall of sudden regulatory discontinuity – remains an open question and a central industry complaint that the May announcement did not resolve.
Reaction has been cautiously positive, with qualifications. Katie Harries, Coinbase’s UK Head of Policy, acknowledged that aggregate issuance caps are more workable than individual limits, but noted that no other jurisdiction is treating stablecoin issuance caps as a baseline requirement in the way the BoE is still considering. Simon Jennings of the UK Cryptoasset Business Council welcomed the directional shift but argued that any final guardrails should be tied to live supervisory metrics rather than fixed thresholds set from day one.
The BoE will publish revised draft rules in June 2026, with final Codes of Practice for systemic stablecoins expected by late 2026 – timed deliberately to align with U.S. legislative developments.
One tension the announcement leaves unresolved: while the BoE is softening restrictions on private stablecoins, its own proposed Digital Pound – the UK’s central bank digital currency – still carries a planned individual holding limit of £10,000. The asymmetry between how public and private digital money will be treated under British law is a policy debate that has barely started.
