UK expands BoE role in stablecoins

TLDR

The UK is giving the Bank of England a new legal mandate to actively promote innovation in payments and stablecoins, while keeping financial stability as its primary duty.

1. The government will add a secondary statutory objective for the BoE to support innovation in payment systems and digital money, including stablecoins, with annual reports to Parliament.
2. This sits on top of a new UK stablecoin rulebook that includes a 40 billion issuance cap per systemic token, specific reserve rules, and lighter capital requirements than the EU.
3. Over 202627, crypto firms and banks can seek authorization to issue regulated sterling stablecoins, and the way the BoE applies this mandate will shape UK stablecoin adoption.

Deep Dive

1. New BoE Innovation Mandate

HM Treasury plans to amend the Financial Services and Markets Bill to give the Bank of England a secondary statutory objective to support innovation in payment systems and digital money, including stablecoins. This objective is explicitly subordinate to the Banks core responsibility for financial stability, meaning it must not back innovations that would undermine systemic safety.

The mandate extends an existing innovation duty from clearing and settlement infrastructure into systemic payment systems that use digital settlement assets, such as regulated stablecoins. The Bank will have to report annually to Parliament on how it is advancing this innovation objective, adding political scrutiny and a clear accountability framework for its approach to digital payments and stablecoins, as highlighted in the governments secondary objective proposal.

2. The UK Stablecoin Rulebook And Global Position

The new mandate lands alongside detailed UK stablecoin rules. In June 2026, the BoE finalized its framework for systemic sterling-pegged stablecoins, removing planned per-holder caps and instead imposing a 40 billion issuance limit per stablecoin, with reserves split between short-term UK government debt and non-interest-bearing central bank deposits, as set out in the BoE policy statement.

The Financial Conduct Authority has also finalized its cryptoasset framework, including cutting stablecoin issuers capital requirement to 1% of circulating value, half the buffer required under the EUs MiCA regime, according to the FCAs stablecoin capital update. Together, this positions the UK as more flexible than the EU while still demanding robust backing and risk controls, in parallel with US efforts like the GENIUS Act.

3. Implications For Stablecoin Issuers And Users

For issuers and platforms, the expanded BoE role means a clearer path to launch regulated sterling stablecoins, but within tight guardrails on issuance size, backing assets, and supervision. Applications for systemic sterling stablecoins are expected to open before year-end, with FCA authorization windows running through 2027 before a mandatory regime takes effect.

For users and institutions, this could gradually increase the availability of pound-pegged stablecoins as an alternative to dollar tokens, especially for UK payments and tokenized assets. However, because the innovation objective is secondary, the Bank can still block or reshape products that it judges to threaten financial stability.

Conclusion

By formally tasking the Bank of England with supporting innovation around stablecoins and digital money, the UK is shifting from cautious oversight toward active facilitation, but within strict stability constraints. The real impact will depend on how the Bank interprets innovation in practice and how aggressively issuers and banks use the new regime. Over the next one to two years, the UK could emerge as a major regulated hub for sterling stablecoins, or remain a conservative outpost if the BoE exercises its new powers narrowly.
