The Financial Conduct Authority opened its authorization window in September, letting crypto firms apply for licenses under Britain’s new regime nearly a year before the full rules take effect in October 2027.
The regulator published its consultation on regulated crypto activities, spelling out which services fall under the regime: trading platforms, custody, dealing, stablecoin issuance, and staking. Firms serving UK customers, including overseas operators, must reorganize around the new framework or exit the market.
The move follows legislation passed in February that brought crypto activities into the FCA’s remit. The regulator describes its goal as an “open, sustainable and competitive” market people can trust.
What firms must do now
Companies can begin applying for authorization this month. Final rules are due this summer, and the full regime goes live in October 2027. That gives applicants roughly a year to prepare for compliance rather than waiting for the last moment.
The consultation sets out guidance for seven regulated activities. The FCA’s approach is activity-based rather than entity-based, which one expert told Decrypt is more flexible than a single license model and aligns well with today’s centralized market structure. It covers intermediated models: issuers, custodians, venues, and staking providers.
The harder question is decentralized finance. The expert noted that both the UK and the EU struggle with how DeFi protocols should operate under the new rules, and argued that “the only truly DeFi project on Earth so far is Bitcoin,” leaving regulators without a clear template for protocols that have no legal entity behind them.
How it compares to other regimes
The UK timeline puts it behind the EU, whose Markets in Crypto-Assets regulation took effect in stages through 2025, and ahead of the United States, where the CLARITY Act is still working through the Senate and the SEC and CFTC are building rules through their own initiatives.
| Jurisdiction | Framework | Status |
|---|---|---|
| EU | MiCA | In force, phased through 2025 |
| UK | FCA crypto regime | Authorization opens September 2026, full regime October 2027 |
| US | CLARITY Act plus agency rules | Senate vote pending, SEC and CFTC acting independently |
For firms operating across borders, the UK’s activity-based perimeter may prove easier to work with than MiCA’s entity licensing. But the FCA has not resolved how DeFi fits, and firms building protocol-level products face uncertainty that centralized businesses do not.
Stablecoins and staking in scope
Two areas carry particular weight. Stablecoin issuance sits inside the regime, which means issuers serving UK users will need authorization, reserve disclosures, and conduct standards. The US Treasury is running a parallel process under the GENIUS Act, opened for public comment on September 9, covering licensing requirements for stablecoin issuers. President Trump signed the GENIUS Act in 2025, establishing a framework that permits banks and other qualified entities to issue stablecoins backed by assets like US Treasuries, with monthly reserve disclosures. Singapore’s central bank has proposed its own licensing framework requiring 100 percent reserves and no interest payments to holders. Issuers now face three different rulebooks for the same product.
Staking is the other addition. Bringing it into scope gives retail investors a regulated route to staking services through authorized providers, something the US has only partially addressed through exchange-traded fund structures.
The FCA’s January consultation on consumer duty and conduct standards for crypto firms laid groundwork for this week’s publication. Firms that began preparing then have a head start. Those waiting for final rules now have a deadline to plan against: October 2027, with authorization applications open today.
Authorization is only the first gate. Once licensed, firms will face ongoing conduct requirements, capital rules, and reporting duties that the FCA has signaled will be closer to traditional finance than to the light-touch approach some jurisdictions took a decade ago. The regulator has already fined firms in adjacent sectors for weak anti-money-laundering controls, and crypto firms should expect the same scrutiny from day one.
Recruitment is one visible effect. Compliance officers with UK crypto experience are scarce, and firms that waited for this window now compete for the same small pool of candidates. Several large exchanges have quietly expanded their London offices over the summer in anticipation of the regime.
The FCA has also signaled that authorized firms will need to segregate customer crypto from company assets, a requirement that follows high-profile collapses elsewhere in the industry. How strictly that rule is drawn will affect how exchanges structure their custody arrangements and whether they can lend or stake customer holdings.
Market participants in London say the authorization process itself may take months. The FCA has historically handled applications in three to six months, and crypto firms should expect detailed questions about governance, source of funds, and technology controls. Firms applying this month could realistically receive approval in early 2027, leaving a narrow runway before the October deadline.
Why the timing matters
The authorization window opens as the industry absorbs several shocks at once. The Liquid Network exploit earlier this month drained about 4,000 BTC from a federated sidechain wallet, and the Senate is days away from a procedural vote on the CLARITY Act that could reshape US market structure. Firms planning a UK launch now have a concrete date and a rulebook to hire against, which compliance teams across the sector have been waiting for since the February legislation passed.
The consultation runs for several weeks, and the FCA expects to publish final rules before the regime takes effect. Firms that delay authorization past the window risk arriving after competitors have locked in approvals.
