The UK Financial Conduct Authority released its final crypto asset policy statement on June 30, setting out prudential capital, market abuse controls, and stablecoin standards for firms operating in the country. One of the headline changes is a cut in the capital coefficient for non-systemic stablecoin issuers, with K-SII reduced from 2% to 1%. The authorization window will open on September 30, 2026, and the broader regime is scheduled to take effect on October 25, 2027.
Stablecoin capital rules are lighter, but not looser
In the final framework, the FCA lowered the capital requirement for non-systemic stablecoin issuance and adopted a simpler structure for qualifying crypto assets traded on UK qualifying cryptoasset trading platforms, or QCATPs. These assets will face a 40% net position requirement and a 40% counterparty default volatility adjustment, replacing the earlier two-tier classification proposal. Industry feedback during multiple consultation rounds had argued that the original model was too complex and too capital-intensive.
The lower capital coefficient does not mean a softer overall regime. The material cited in the source says qualifying UK stablecoin issuers will be barred from distributing interest generated by reserve assets to holders. That separates stablecoins from fund-like investment products and narrows how issuers can structure their offerings in the UK market.
Market manipulation and insider dealing rules now reach crypto
A major part of the policy package is the introduction of a market abuse framework covering insider dealing and market manipulation. Under the new rules, QCATPs must conduct due diligence, apply asset admission standards, and publish qualifying disclosure documents for assets approved for trading. The previous exception that allowed fungible cryptoassets to list without disclosure documents has been removed.
The framework draws heavily from the UK’s long-standing market abuse regime in traditional finance. Large platform operators will also be responsible for monitoring across platforms and reporting suspicious market abuse activity. Disclosure duties around inside information and notice obligations for intermediaries are also spelled out in more detail.
Licensing timeline is fixed, and MLR registration is not enough
The FCA said authorization applications will open on September 30, 2026 and close on February 28, 2027. The full regime is expected to begin on October 25, 2027. Firms currently registered under the Money Laundering Regulations, or MLRs, will not be grandfathered into the new system. Any company carrying out crypto asset activities covered by the regime will need to apply for fresh FCA authorization.
The regulator also plans to offer pre-application support meetings starting in July. For exchanges, custodians, wallet providers, staking services, and qualifying stablecoin issuers, the preparation phase has effectively started.
MiCA is moving on a similar timeline, while DeFi stays outside for now
The FCA package arrives almost in step with the end of the EU MiCA transition period on July 1. According to the source material, crypto asset service providers without MiCA authorization will no longer be able to rely on transitional arrangements to keep operating in the EU. The UK and EU frameworks point in the same direction: stronger compliance, formal licensing, and tighter operating standards. The details differ, though, and MiCA is described in the source as stricter on prudential and custody requirements.
The UK regime covers exchanges, wallets, custodians, staking services, and qualifying stablecoin issuers. DeFi remains outside the framework for now. The FCA is expected to publish separate guidance on what counts as “truly decentralized” activity, leaving that boundary unresolved at this stage.
