BoE signals flexibility on UK stablecoin caps

TLDR

The Bank of England has signaled it is open to softening its proposed caps and reserve rules on UK sterling stablecoins.

1. Deputy Governor Sarah Breeden told lawmakers the BoE is genuinely open to alternatives to strict holding caps on systemic sterling stablecoins.
2. Current proposals include per user caps and a 40 percent unremunerated reserve deposit at the BoE, which industry argues would cripple UK stablecoin business models.
3. The outcome will hinge on a House of Lords inquiry and ongoing consultations that could reshape how attractive the UK is as a stablecoin hub.

Deep Dive

1. What The BoE Just Signaled

In evidence to the House of Lords Financial Services Regulation Committee, Deputy Governor Sarah Breeden said the BoE is genuinely open to other ways of achieving the objective behind its proposed holding limits on systemic stablecoins, stressing the very real risk of deposits moving from banks into stablecoins and cutting credit to households and firms. This is being reported as a willingness to reconsider caps that had sparked a backlash from industry groups and some lawmakers, rather than a retreat from regulating stablecoins altogether.

The BoEs goal remains clear. Any stablecoin used as money in the UK economy should be as robust as the money we use today issued by banks, as Breeden put it in one recent overview of the regime.

2. What The Current Caps And Rules Would Do

Under the consultation regime for systemic sterling stablecoins, transitional holding limits include roughly 10,000 to 20,000 per individual and around 10 million per business, plus a requirement that 40 percent of reserves sit as unremunerated deposits at the BoE and the rest in short term UK government debt. These safeguards, detailed in coverage of the draft rules, are designed to prevent a rapid flight of deposits from banks while making stablecoins highly resilient, but they also act like a built in tax on issuers balance sheets and a hard ceiling on how deeply a UK resident can use stablecoins in daily payments.

Industry associations and issuers argue that such limits and reserve mechanics could make sterling stablecoins uneconomic and push serious issuance to other jurisdictions with regimes more like MiCA in the EU, a concern echoed in analysis of the consultation and the industry response.

3. What To Watch Next For Crypto Users

Several near term milestones matter.

1. The House of Lords committee inquiry into whether the BoE and FCA regimes are proportionate will heavily shape political pressure on the BoE to adjust caps or reserve rules.
2. The FCAs stablecoin sandbox and the BoEs timeline to accept applications for sterling stablecoin issuers by the end of the year, as highlighted in recent testimony, will show whether firms actually step forward under the draft regime.
3. Final rule text on holding limits, treatment of reserves and how far unhosted wallets are constrained will determine whether the UK becomes a credible base for regulated stablecoin projects or remains mainly an import market.

Conclusion

The BoE is not backing away from a tightly supervised sterling stablecoin regime, but it is clearly responding to industry pushback by inviting alternatives to strict caps and reserve mechanics. For crypto users, the eventual calibration of holding limits and reserve treatment will decide whether UK issued stablecoins can become meaningful payment rails or whether activity continues to concentrate in jurisdictions with more economically viable rules.
