The UK’s Financial Conduct Authority has drawn a clear line in the sand on UK stablecoin regulation — and it runs noticeably below the bar set by Brussels. In a landmark framework document published Tuesday, the FCA slashed the capital requirement for stablecoin issuers from 2% to 1% of total stablecoins in circulation, positioning Britain as a meaningfully lighter-touch regime than the European Union’s Markets in Crypto Assets regulation, which keeps its equivalent buffer at 2%.
Summary
Key takeaways
- The FCA reduced stablecoin issuers’ capital requirement from 2% to 1% of total stablecoins in circulation, undercutting the EU’s MiCA standard.
- The Bank of England dropped plans to impose a £20,000 ($26,500) cap on individual stablecoin holdings.
- Crypto exchanges must set aside 40% of trading capital to cover potential losses and apply a 40% volatility adjustment to collateral when lending or trading.
- The full authorization regime takes effect on October 25, 2027; firms can apply between September 30, 2026, and February 28, 2027.
- Backing pools for stablecoin reserves may now hold excess assets of up to 5%, and intragroup custody arrangements are permitted subject to safeguards.
UK’s FCA reduces stablecoin capital requirements
The decision to cut the capital buffer in half is not a minor technical tweak. For larger stablecoin issuers in particular, the difference between holding 1% and 2% of total issuance in reserve capital represents a significant operational and competitive variable. The FCA framed the change as making the prudential framework more proportionate for larger issuers while keeping the overall regime robust — a careful balancing act between encouraging growth and maintaining financial safeguards.
How the UK now compares to the EU’s MiCA
The divergence from MiCA is deliberate and measurable. Under the EU’s framework, stablecoin issuers must back their operations with a 2% capital requirement — double what the FCA now demands. That gap could become a competitive pull factor for crypto firms deciding where to base their stablecoin operations, particularly those looking to serve European markets while operating under a softer prudential regime from London.
The broader framework finalized Tuesday covers the full range of regulated cryptoasset activities: trading platforms, custodians, lending and borrowing providers, staking firms, and certain decentralized finance entities where a controlling party can be identified. The FCA also removed an exception that previously allowed fungible cryptoassets to be listed on qualifying trading platforms without a disclosure document — a move that tightens transparency standards even as capital rules loosen.
FCA’s goals for simplifying crypto regulation
Simplification was a stated priority throughout the process. The FCA explicitly said its aim was to make key elements of the regime more workable in practice, responding to industry feedback that earlier proposals were overly complex. The revised framework replaces a previously proposed two-tier classification system for cryptoassets with a single standard.
New capital and collateral rules for crypto exchanges
For crypto exchanges, the rules introduce a clear and uniform set of prudential requirements. Under the final framework:
- Exchanges must hold 40% of their trading capital to cover potential losses.
- A 40% potential loss must be applied to the value of collateral when lending or trading with other parties — replacing the previous two-tier classification with a single net risk position and counterparty default volatility adjustment.
These requirements apply to UK qualifying cryptoasset trading platforms, which must also conduct due diligence, meet admission criteria, and publish qualifying cryptoasset disclosure documents for any asset admitted to trading. The market abuse framework, meanwhile, introduces formal rules against insider trading and market manipulation, with the FCA retaining an industry-led approach for large platform operators while narrowing their on-chain monitoring obligations.
David Geale, the FCA’s executive director of payments and digital finance, described the package as a significant milestone, saying it aims to give firms regulatory certainty while preserving space for innovation. He noted that consumers will benefit from standards more closely aligned with those applied to other financial services — while still acknowledging that investment risks in cryptoassets remain real.
Bank of England drops stablecoin holding cap
The FCA’s move does not stand alone. Shortly before the framework was published, the Bank of England reversed its earlier proposal to limit how much in stablecoins any individual could hold, abandoning a planned £20,000 ($26,500) cap. That plan had drawn criticism from the crypto industry as an unnecessarily restrictive constraint on a maturing market. Its removal signals a coordinated pivot by UK financial authorities toward a more permissive stance on stablecoin adoption.
Together, the two decisions — the FCA’s lower capital requirement and the Bank of England’s withdrawal of the holding cap — paint a consistent picture of the UK deliberately calibrating its crypto rules to remain competitive globally, particularly as the US and EU push ahead with their own frameworks. Whether that lighter touch translates into genuine business migration from the continent, or simply reduces friction for firms already operating in London, will depend heavily on how the authorization window between September 30, 2026, and February 28, 2027 plays out in practice.
Existing Money Laundering Regulation registrations will not automatically convert to the new authorization. Until the regime formally takes effect in October 2027, the FCA’s oversight of crypto firms remains limited to financial promotions and anti-money laundering requirements — meaning the real test of this framework’s effectiveness is still more than a year away.
FAQ
What is the new stablecoin capital requirement set by the UK FCA?
The Financial Conduct Authority has reduced the capital requirement for stablecoin issuers to 1% of the total value of stablecoins in circulation, down from the previously proposed 2%.
How does the UK FCA’s stablecoin capital requirement compare to the EU’s MiCA rules?
The FCA’s 1% capital buffer is half the EU’s requirement. Under the EU’s Markets in Crypto Assets (MiCA) regulation, stablecoin issuers must maintain a 2% capital buffer, making the UK’s regime notably lighter in this specific area.
What changes has the FCA made regarding crypto exchanges’ capital requirements?
Crypto exchanges operating in the UK must set aside 40% of their trading capital to cover potential losses. They must also apply a 40% potential loss adjustment to the value of collateral when lending or trading with other parties, under a single net risk position requirement that replaces a previously proposed two-tier system.
Did the Bank of England keep its proposed cap on individual stablecoin holdings?
No. The Bank of England abandoned plans to impose a £20,000 (approximately $26,500) cap on the value of stablecoins an individual could hold, representing a significant policy reversal ahead of the FCA’s final framework publication.
