BoE Softens Stablecoin Cap Plans to Keep Issuers Onshore

BoE Signals Revision of Stablecoin Reserve and Cap Rules

The Bank of England is re-evaluating stablecoin reserve requirements and issuance caps, according to reports, following sustained industry pressure that the initial proposals were overly conservative. The simple market read treats this as a dovish regulatory pivot, lifting sentiment across crypto-linked assets. The better read focuses on what changes and why: the review targets the exact rules that would have made the UK an uncompetitive jurisdiction for stablecoin operations, threatening to drive issuers offshore.

Officials are specifically looking at the £20,000 individual holding limit and the composition of reserve assets that backed the previous consultation. Stiff reserve mandates raise the cost of issuing sterling-pegged stablecoins because a higher share of capital must sit in low-yield, highly liquid instruments, compressing net interest margins. Relaxing both elements improves the unit economics for potential issuers and makes it more attractive for existing dollar-denominated stablecoin operators to launch sterling variants or relocate custody infrastructure to London.

The chain of impact starts with stablecoin issuers directly. Circle, the operator of USDC, had publicly flagged the UK’s framework as a barrier to entry. A softer regime reopens the door for a regulated sterling coin that could tap into the City’s institutional payment rails. The previous cap design would have also restricted how much of a stablecoin any single user could hold, limiting their utility in wholesale settlement and on-chain trading. Easing that cap removes an artificial ceiling on velocity and addressable market size.

Which Parts of the UK Crypto Sector Absorb the Read-Through

The read-through travels through three distinct layers. First, UK-licensed crypto exchanges and brokerages that rely on stablecoin pairs for liquidity. A local sterling stablecoin under clear BoE rules reduces settlement risk and the need to constantly convert into dollars or euros, lowering friction costs for pound-denominated order books. Second, payment-focused fintechs and neobanks that have been exploring stablecoin rails for cross-border transfers gain a clearer compliance path. Third, the custody and compliance infrastructure layer–firms that provide wallet services, KYC/AML checks, and insurance for digital assets–benefit from a growing stablecoin float onshore.

There is no named peer list in the immediate reporting. The direction of travel, however, makes it likely that major dollar-stablecoin issuers re-engage with the Prudential Regulation Authority. For listed crypto-exposed vehicles, the catalyst is indirect: BTC and ETH trading venues that operate in the UK can expect higher net inflows if sterling gateways become more efficient. Exchange operators that already hold FCA registration face a lower incremental compliance burden than late entrants, giving an edge to firms with existing anti-money laundering approvals.

The policy shift parallels a broader post-Brexit recalibration. The UK has signalled repeatedly it wants to be a competitive digital asset hub, and the previous £20,000 cap was seen as incompatible with that ambition. Softer stablecoin regulation aligns the UK more closely with the EU’s Markets in Crypto-Assets framework, which permits wider use but imposes reserve and redemption safeguards. A level playing field reduces the risk that stablecoin activity consolidates in Dublin or Luxembourg while London retains the trading volume.

The next concrete marker is the formal outcome of the BoE’s review. No new figures have been published, and it remains unclear whether the cap will be raised, removed entirely, or replaced with a tiered system. Traders should monitor the next consultation paper or speech from PRA officials, which will reveal whether the softening is marginal–just a higher cap–or structural, including a redefinition of eligible reserve assets. That distinction determines how many stablecoin operators actually commit capital to a UK entity versus waiting for the rulebook to stabilise further.
