The FCA’s Own Numbers Put Its Crypto Regime at £120m…

The Financial Conduct Authority's own cost-benefit analysis puts the net economic benefit of Britain's incoming crypto regulatory regime at approximately £120 million, despite estimating that implementing and operating the framework will generate £1.315 billion in costs.The FCA estimates total benefits of approximately £1.435 billion over its 10-year appraisal period. That leaves benefits exceeding costs by only about 9.1% of the modeled cost base. The numbers are present-value estimates rather than cash expenditures occurring immediately. They are expressed in 2026 prices and discount future costs and benefits at 3.5%.The FCA expects approximately 325 firms to fall within the regime. From October 25, 2027, businesses conducting regulated crypto activities including trading, custody, intermediation and arranging staking will generally require FCA authorization.

One Assumption Provides Half the Benefits

The composition of the FCA's £1.435 billion benefit estimate is particularly significant. Approximately £735 million—51% of the total—is attributed to the value consumers are expected to place on stronger regulatory protections. This is not £735 million of fraud that the FCA predicts its rules will prevent.Instead, it represents a modeled consumer-welfare benefit associated with greater confidence and protections under the regulated framework. Without that £735 million assumption, the remaining quantified benefits would total approximately £700 million, leaving them about £615 million below the £1.315 billion cost estimate. The FCA approaches the uncertainty through a breakeven calculation.Across an estimated 4.5 million existing UK crypto consumers, the regime would need to deliver approximately £136 of additional protection value per consumer over 10 years—or £13.60 annually—to offset the modeled costs. The regulator considers positive consumer benefits plausible, citing research indicating that users value stronger protections. The framework will introduce requirements covering financial resilience, market abuse, disclosures, operational resilience, stablecoin issuance and consumer treatment.

£1.315 Billion Is Not a Compliance Invoice

The cost figure also requires context. The £1.315 billion represents the FCA's aggregate economic estimate across the appraisal period rather than an amount that crypto companies collectively pay regulators. It combines implementation and ongoing compliance costs associated with different components of the new framework. The regime follows the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, passed by Parliament in February.The legislation significantly expands the FCA's jurisdiction beyond the anti-money-laundering and financial-promotion requirements that currently form much of Britain's crypto oversight. Applications under the new authorization regime open September 30 and run through February 28, 2027. Existing registrations will not automatically convert into authorization.That creates a potentially demanding gateway for companies already serving UK customers. Since January 2020, the FCA received 417 applications under its narrower crypto registration framework and determined 391. Of those, 263 were withdrawn before a decision, while 68 resulted in registrations, 46 were rejected and 14 refused.Those historical numbers cannot be directly projected onto the new regime because the authorization standards and activities covered are different. The FCA argues its final framework balances stronger protection with competitiveness, including simplifying some capital requirements after industry consultation.Its economic analysis ultimately supports that conclusion—but by a relatively narrow modeled margin. A £120 million net benefit over 10 years represents less than one-tenth of the £1.315 billion cost base. And because more than half of the modeled benefits depend on assigning economic value to stronger consumer protections, whether the regime ultimately produces the FCA's expected return will depend on outcomes that cannot yet be observed.The regulator plans a post-implementation review. By then, the theoretical £120 million surplus can begin to be tested against what Britain's crypto regime actually costs—and what consumers ultimately receive in return.
