BoE softens stance on UK stablecoin caps

TLDR

The Bank of England is signalling it may relax its proposed caps and constraints on U.K. pound stablecoins after strong industry pushback.

1. Deputy Governor Sarah Breeden said the BoE is genuinely open to changing its strict limits on stablecoin holdings and design.
2. The current proposals require 100% high quality reserves, tight BoE/FCA oversight, and de facto caps that many issuers say make British pound stablecoins uncompetitive.
3. Next comes revised rule text after consultation, which will determine how attractive the U.K. really is as a base for stablecoin issuers and trading venues.

Deep Dive

1. What The BoE Is Softening

In recent comments, Deputy Governor Sarah Breeden said the Bank of England is genuinely open to other ways of achieving the objective and hinted regulators may soften their strict approach to limits on stablecoin holdings that drew a backlash from the digital asset industry. This marks a shift away from a hard line on caps that were justified as protection against sudden shifts of deposits from banks into stablecoins.

At the same time, Breeden repeated that the BoE still sees a very real risk in deposit flight from banks to stablecoins, so the goal of protecting financial stability is not changing, only potentially the tools used to achieve it.

2. How The Existing UK Rules Look

The draft framework for sterling stablecoins would require issuers designated as systemic to hold at least 40% of reserves as deposits at the Bank of England and up to 60% in short term U.K. government debt, keep coins redeemable at par, and back them 100% with high quality assets, with systemic issuers directly supervised by the BoE and trading focused use cases regulated by the FCA. These requirements were meant to make pound stablecoins safe and bank like, but they also impose heavy balance sheet and compliance costs that can limit flexibility and yield.

Industry groups argue that strict reserve composition rules and implied caps on certain types of use and rewards risk pushing innovation and liquidity into other jurisdictions, especially when the EUs MiCA and U.S. regimes are also competing for issuers. Coinbase, for example, is lobbying the U.K. to ease proposed limits on stablecoin rewards and reserve rules so products remain attractive for users and partners.

3. What To Watch Next For Crypto Users

In the near term, the key signal will be updated BoE and Treasury consultation documents that turn this softer rhetoric into concrete rule changes, including any revisions to caps on holdings, rewards, or specific use cases. Watch also how closely the BoE coordinates with the FCA on trading use cases, since a split between payment regulation and trading regulation can create friction for exchanges and DeFi integrations.

For traders and builders, the practical questions are whether GBP stablecoins will be cheap to issue, scalable without artificial caps, and usable on major U.K. facing exchanges and payment apps. If the BoE lands on risk based tools rather than blunt caps, the U.K. could become a more credible hub for regulated stablecoin activity relative to the EU and U.S.

Conclusion

The Bank of England is not abandoning its concerns about bank funding or systemic risk, but it is clearly stepping back from an inflexible hard cap mindset on stablecoins. If upcoming revisions preserve strong safeguards while easing caps and rigid constraints, GBP stablecoins could become more viable for issuers and more useful for U.K. based crypto users and platforms.
