Last updated on 7 July 2026
FCA crypto rules are finalised in the UK. From 25 October 2027, almost every crypto business serving UK customers will need full FCA authorisation, stablecoins must be fully backed and redeemable at face value, and investors will get protections similar to those in traditional finance.
On 30 June 2026, the Financial Conduct Authority released a package of policy statements that completes the UK’s cryptoasset regime.
This was not a rushed decision. The regulator spent more than three years building it, working through four discussion papers and ten consultation papers since 2023.
Hundreds of firms, banks, lawyers, trade bodies, and private individuals sent in feedback, and the final rules changed in visible ways because of it.
It tells us the FCA treated this as a negotiation with the market, not a decree handed down from above.
To understand why this is such a shift, look at where the UK started.
Since January 2020, the FCA’s role in crypto was narrow. It registered exchanges and wallet providers for anti-money laundering purposes and, from 2023, policed how firms advertised crypto to UK consumers.
Everything else, from how exchanges held customer assets to whether a token issuer told the truth, sat outside its reach. The new regime closes that gap almost entirely.
The team at Crypto Accountants walks you through each part and examines what it actually means in practice.
The FCA Crypto Rules 2026: What They Actually Published?
The Five Policy Statements
The package rests on five documents, and each one targets a different layer of the market:
- PS26/9 covers admissions and disclosures (A&D) plus MARC, the new market abuse regime for crypto
- PS26/10 sets the rules for stablecoin issuance
- PS26/11 covers regulated crypto activities such as trading, custody, lending, and staking
- PS26/12 creates a prudential (capital) regime for crypto firms
- PS26/13 explains how the existing FCA Handbook applies to crypto businesses
Read together, these five documents follow a deliberate logic.
One set of rules governs how tokens enter the market and how trading stays clean.
Another governs the money-like instruments, stablecoins, which carry the highest expectations.
A third governs the services wrapped around tokens.
The fourth makes sure firms hold enough capital to absorb losses.
And the fifth plugs crypto firms into the standards that already apply to banks and investment firms, such as the Consumer Duty and the Senior Managers and Certification Regime (SM&CR).
The FCA also published supporting guidance on the Consumer Duty (FG26/5), operational resilience (FG26/6), and international firms (FG26/7), plus a single combined cost-benefit analysis, which concluded the rules should deliver net positive benefits to market participants.
The Legal Foundation
All of this stands on the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, which Parliament passed on 4 February 2026.
Companies should not miss the significance of using FSMA, the same statute that governs banks and asset managers.
The UK chose to fold crypto into its main financial services framework rather than build a separate, lighter regime the way some jurisdictions have.
FCA will supervise a crypto exchange with the same toolkit, and largely the same expectations, it applies to a stockbroker.
Think of it like this. Before, running a crypto exchange in the UK was like driving a car that only needed an emissions check.
Now the whole vehicle gets inspected: brakes, steering, seatbelts, everything.
The Key Dates You Cannot Miss
25 October 2027: The Regime Goes Live
The full scope of regulated activities takes effect on this date.
Every firm carrying out a regulated cryptoasset activity in the UK will need FSMA Part 4A authorisation unless an exemption applies.
The sixteen-month runway between publication and commencement is intentional.
Authorisation is slow, and firms need time to build compliance functions, appoint senior managers, and raise capital.
Firms that treat October 2027 as the date to start preparing, rather than the date to be ready, will find themselves locked out.
30 September 2026 to 28 February 2027: The Savings Window
This five-month window is arguably the most commercially important date in the entire package.
Firms already operating in the UK can keep trading while the FCA assesses their application, but only if they apply within it.
The mechanics reward speed: the earlier a firm applies, the longer it can operate under the transitional cover while its application sits in the queue.
A firm that applies after the window closes gets no such protection and may have to suspend its crypto activities entirely until authorisation arrives.
For a trading platform, that could mean months of zero revenue.
The FCA’s advice is blunt: apply early.
No Automatic Conversion
This is the detail that will catch out the most firms.
A registration under the Money Laundering Regulations, held since as far back as January 2020, does not carry over.
Neither does authorisation under the Payment Services or Electronic Money Regulations, nor reliance on a s.21 financial promotions approver.
Every in-scope firm starts from zero and must prove it meets the FSMA Threshold Conditions: adequate resources, suitable management, and a business model the regulator can actually supervise.
History suggests this filter bites hard.
When the MLR registration regime launched in 2020, a large share of applicants withdrew or were rejected.
Firms should expect the same rigour, applied to a much longer checklist.
Stablecoins Get the Strictest Treatment in FCA Crypto Rules 2026!
Stablecoins are tokens that hold a steady value, usually pegged to a currency like the pound.
The FCA treats them differently from other cryptoassets for one reason: people use them like money.
If a speculative token crashes, an investor loses a bet they knowingly made. If a stablecoin breaks its peg, holders lose what they believed was cash.
The collapse of TerraUSD in 2022, which erased roughly $45 billion of value in days, showed exactly how that failure mode plays out.
So the UK regime requires UK-issued qualifying stablecoins to be fully backed by real assets and redeemable at par.
You can always swap back one token worth one pound for another pound.
What Changed in the New FCA Crypto Rules After the Feedback?
The consultation on stablecoins and custody (CP25/14) drew 80 responses, the largest of any paper in the series, and the final rules moved in several practical ways.
Issuers no longer need to forecast redemption patterns when composing their backing pool, which removes a modelling exercise firms argued was speculative at best.
Backing assets must sit in a statutory trust, meaning holders have a legal claim on those assets if the issuer fails, rather than queuing as ordinary creditors.
Issuers can hold up to 5% excess in the backing pool as a buffer, and limited intragroup custody is now permitted with safeguards.
Redemption timelines were also adjusted to be operationally realistic.
Picture a company issuing a pound-pegged stablecoin used by 100,000 people. It must hold safe, liquid assets covering every token, ring-fence them in trust, and honour redemptions on defined timelines.
The analytical takeaway is that the FCA is positioning regulated stablecoins as credible payment instruments, and it says openly that further work on payments use cases and issuer resolution is coming.
New Rules for Trading, Custody, Lending, and Staking
1- Trading Platforms and Brokers
Operators of qualifying cryptoasset trading platforms (QCATPs) and intermediaries face conduct standards, best execution duties, and transparency requirements.
The FCA made a notable choice here: it kept the framework principles-based rather than prescriptive.
Best execution, for instance, requires effective overarching arrangements with periodic monitoring and post-trade analysis, not a check on every single transaction.
That mirrors how equities markets are supervised and keeps compliance costs proportionate.
The regulator also removed principal dealers from pre-trade transparency after feedback showed the requirement did not fit a dealer trading on its own book.
2- Custody: The Biggest Win for Consumers
Custody is where the analysis gets most interesting, because custody failure is where crypto consumers have historically lost the most.
When FTX collapsed in 2022, customer assets were commingled with the firm’s own funds, and users spent years fighting through bankruptcy for partial recovery.
The FCA’s answer is CASS 17, a new client asset regime built for crypto. Firms must maintain accurate books and records, run regular reconciliations, respect client ownership rights, and manage private keys under a technology-agnostic standard.
The design goal is that if a UK custodian fails, client assets are identifiable, legally separate, and returnable.
The final rules include pragmatic adjustments: the settlement float limit rose to 2%, targeted exceptions to trust requirements were introduced, and specified investment cryptoassets (RSICs) will sit under the existing CASS 6 regime for now.
Client money connected to crypto safeguarding falls under CASS 7.
A consultation on custodian failure and distribution rules follows later this year, which signals the FCA knows rules on paper only matter if they work in an actual insolvency.
3- Lending and Borrowing
Crypto lending was one of the clearest sources of consumer harm in the last cycle.
Celsius and BlockFi took retail deposits, lent them out at risk, and froze withdrawals when markets turned.
The UK response keeps retail protections firm: enhanced disclosures, explicit consent, appropriateness testing, over-collateralisation, and negative balance protection so a client can never lose more than they committed.
The FCA did flex where the logic supported it.
Firms may now stake retail client collateral within CASS 17 safeguards, and the limit on automatic collateral top-ups applies to firms only, leaving clients free to top up positions manually.
4- Staking
Staking, where holders lock tokens to help run a blockchain network and earn rewards, gets a disclosure-and-consent framework rather than a ban.
Firms must explain the risks, set clear contractual terms, obtain client consent, and keep records for all clients.
The FCA also fixed a genuine operational problem from the draft rules: auto-staking of current and future holdings can continue under a single consent, subject to conditions and an annual notification.
Record-keeping rules were clarified for liquid staking models, and perimeter questions will be handled through separate guidance.
5- DeFi
Decentralised finance receives the most cautious treatment in the package, and deliberately so.
The rules apply only where an identifiable controlling entity stands behind a protocol, consistent with the perimeter the Treasury defined.
Truly decentralised systems sit outside the regime for now. Rather than force a binary answer, the FCA will assess scope case by case and consult on tailored guidance, including objective indicators of decentralisation.
The honest analytical read: the regulator knows that “decentralised” is usually a marketing claim, and it wants evidence-based tests before writing permanent rules.
Capital Rules Became Simpler and Cheaper in New FCA Crypto Rules 2026
The K-SII Cut
Prudential rules decide how much capital a firm must hold to absorb losses.
For stablecoin issuers, the key variable is K-SII, a capital charge scaled to the size of the issuance.
The FCA halved the coefficient from 2% to 1% after industry feedback argued the original calibration penalised scale.
On a £500 million stablecoin, that is the difference between £10 million and £5 million of required capital.
The direction of travel is clear: the FCA wants large, well-run issuers to find the UK economically viable.
One Tier Instead of Two
The consultation proposed sorting cryptoassets into Category A and Category B for market risk purposes, each with its own treatment.
Respondents called it complex, so the FCA scrapped it.
The final framework applies one test: can the token be prudently valued, and is it admitted to a UK qualifying trading platform?
If yes, it attracts a 40% net position requirement and a 40% volatility adjustment for counterparty risk. If no, the holding is deducted from regulatory capital entirely, with a 100% volatility adjustment.
The economic incentive is elegant.
Firms that hold obscure, hard-to-value tokens pay for it in capital, which quietly steers balance sheets toward liquid, exchange-traded assets.
Lighter Disclosure for Smaller Firms
The FCA dropped the requirement to publicly disclose two supervisory thresholds (OFTR and LATR) and built a proportionality test around them.
If a firm’s binding capital requirement is just the permanent minimum, you don’t need any public prudential disclosure.
Disclosure only kicks in when fixed overheads or K-factor requirements bind, which in practice means larger firms.
These calculations shape pricing, growth plans, and even whether the UK makes sense as a base.
This is exactly where Crypto Accountants UK earn their keep, because computing own funds requirements under the new CRYPTOPRU sourcebook is not a job for a generalist bookkeeper.
What Do the New FCA Crypto Rules 2026 Mean for Regular Investors?
1- Crypto Stays High Risk
Be clear about one thing.
The FCA states plainly that cryptoassets are high risk and will remain high risk under the regime.
Regulation changes the conduct of firms, not the volatility of the asset.
You can still lose everything you invest, and the regulator wants you to know that before anything else.
2- Real Protections Arrive
What changes is the environment around the investment.
Firms must comply with the Consumer Duty, the FCA’s flagship standard requiring fair value and good outcomes.
MARC introduces market abuse controls, so insider dealing and manipulation on UK platforms face consequences for the first time.
Token issuers must publish honest disclosure documents before admission to trading, backed by due diligence standards.
And CASS custody rules mean your assets should survive your platform’s failure.
None of this existed for UK crypto users two years ago.
3- The Market Context
The FCA’s own consumer research, in its sixth edition as of December 2025, shows ownership concentrated among younger consumers, men, higher-income earners, and some ethnic minority groups.
The regulator’s equality analysis makes a further point worth noting: it expects clearer regulation to increase consumer confidence and broaden participation, which is precisely why proportionate protections matter.
Combine that with the October 2025 lifting of the retail ban on certain crypto exchange-traded notes, and the UK’s posture is unmistakable.
What Firms Should Do Right Now?
1- Run a Gap Analysis
Map your current activities against the regulated activities in the Cryptoassets Regulations and identify which policy statements bind you.
The exposure differs sharply by business model. A custodian lives in CASS 17 and the prudential rules.
A stablecoin issuer lives in PS26/10 and the backing asset requirements. A trading platform carries the heaviest MARC obligations. Reading the wrong chapters wastes the one resource firms lack: time.
2- Prepare a Clean Application
The FCA offers information sessions and a Pre-Application Support Service (PASS), but the burden of proof sits with the firm.
Threshold Conditions require adequate financial and non-financial resources, which means audited records, credible capital calculations, and defensible tax positions.
Many firms bring in a Crypto Tax Accountant at this stage, since HMRC compliance and FCA readiness overlap heavily, and messy tax affairs can sink an otherwise strong application.
3- Watch the Moving Parts
The regime is not finished.
In April 2026, the Government proposed excluding some UK stablecoin activities from the dealing and arranging perimeter, shifting them toward a future payments regime.
Consultations on firm failure and resolution, financial crime guidance, and regulatory reporting all arrive later this year, and work on derivatives, DLT, and audit requirements continues.
The FCA has also committed to a formal review roughly two years after commencement.
Firms should treat compliance as a living programme, not a one-off project.
Need Help Getting Ready after the new FCA Crypto Rules?
With the new FCA crypto rules, the UK moved from patchy oversight to a complete crypto rulebook. The final rules show a regulator that listened: capital charges came down, complexity was stripped out, and impractical requirements were fixed.
Firms get certainty and a credible home base.
Consumers get real protections without a ban.
But the transition demands work, and the savings window from 30 September 2026 to 28 February 2027 is the deadline every crypto firm should circle in red.
The new FCA regime raises the bar for record-keeping, capital reporting, and tax compliance.
