What changes under the UK’s new crypto rules?

For most of the last decade, the UK government’s posture on crypto could be summed up in two words: tread carefully. Firms had to register with the Financial Conduct Authority for anti money laundering purposes, but the underlying activity, buying and selling tokens, sat largely outside the rulebook that governs the rest of the financial system. That position has been quietly dismantled. The UK is now in the middle of moving crypto from a lightly supervised corner of the economy into the mainstream of financial regulation, and the practical effects are starting to show up for ordinary investors.

The headline shift is one of category. Crypto activity, particularly trading, custody, lending and the issuing of stablecoins, is being brought inside the same authorisation regime that already covers banks, brokers and asset managers. The Financial Services and Markets Act 2023 gave the Treasury the legal mechanism to do this. What followed has been a phased rollout, deliberately slow, designed to avoid the kind of overnight regime change that closes off market access for ordinary people while the rules bed in.

The first visible change for most readers was the financial promotions regime. Since October 2023, any communication that promotes a cryptoasset to UK consumers has had to comply with the same standards that apply to a stock trading app or a fund manager. Promotions must be clear, fair and not misleading. They must carry a risk warning that crypto is high risk and the investor may lose all their money. There is a twenty four hour cooling off period for first time buyers on a given platform, and a personalised risk warning that cannot be skipped. None of this stops anyone buying crypto, but it has changed what the path looks like, and it has pushed several offshore platforms either to seek FCA approval or to stop marketing to British users altogether.

Alongside the promotions regime, the Travel Rule has been in force since September 2023. When crypto moves between regulated firms above a small threshold, identifying information about the sender and the recipient must travel with it, in the same way it would for a wire transfer between banks. Most users will never see this happening, but it is the reason that UK exchanges sometimes ask extra questions when withdrawing to or receiving from another platform. The intent is to close the gap between traditional finance and crypto on financial crime checks.

The bigger shift is regulatory perimeter. The Treasury confirmed that the long term plan is to bring most cryptoasset activities, including running an exchange, holding customer assets in custody, and operating a lending or staking service for retail clients, inside the FCA’s full conduct regulation. Firms operating these services will need authorisation, hold a minimum level of capital, separate client assets from their own, follow conduct of business rules on disclosures and complaints, and answer to the Financial Ombudsman if customers raise disputes that cannot be settled directly. This is the layer of consumer protection that crypto has historically lacked, and it represents the most consequential change in the package.

Stablecoins have been treated as a special case. Fiat backed stablecoins used for payments are being pulled into the same regulatory framework that covers e money and payment services, rather than being lumped in with speculative tokens. The reasoning is straightforward. A token that promises to be worth a pound or a dollar at all times, and that is used to settle real transactions, is functionally a payment instrument. If issuers fail to back the token properly, holders lose their balance. The new rules require reserves to be held in safe assets, segregated from the issuer’s own funds, and made redeemable on demand. Algorithmic stablecoins, which try to hold a peg through code rather than reserves, are being kept out of the payments regime entirely after the collapse of TerraUSD in 2022 made the risks brutally clear.

Tax reporting has also tightened. From the 2024 to 2025 tax year onwards, Self Assessment returns include a dedicated section for cryptoasset gains, separate from other capital gains. This is administrative rather than substantive, the underlying tax treatment has not changed, but it means HMRC can see crypto activity at a glance rather than reading it out of generic gains figures. Exchanges operating in the UK have also become more proactive about producing transaction reports that map cleanly to a tax return. Anyone treating crypto as informally invisible to HMRC should assume that visibility is now the default.

The Digital Securities Sandbox, which went live in early 2024, sits alongside all of this. It is a controlled environment in which firms can issue, trade and settle traditional financial instruments such as shares and bonds on distributed ledger technology, with the regulators watching closely and adjusting rules in response to what works. It is not a retail product, but it matters because it signals that the UK sees blockchain as plumbing for the future of capital markets, not just as the rails for speculative coins. Tokenised funds, tokenised gilts, and tokenised money market instruments have all been part of early pilots.

For investors, the practical takeaways are fairly clean. Use platforms that hold the relevant FCA permissions, because the protections on offer scale up with the firm’s regulatory status. Read the risk warnings rather than clicking past them, because the cooling off period and the promotions rules exist to slow down a category of decision that often gets made too fast. Keep proper records of every disposal, because the dedicated tax section will be looking for them. And treat any platform that aggressively markets to UK users without clear FCA registration as a red flag rather than a bargain.

None of this turns crypto into a safe asset. Volatility, project failure and outright fraud remain features of the market, and regulation cannot abolish any of them. What the new rules do is align the UK consumer experience of crypto with the rest of financial services: clearer disclosures, segregated client money, real recourse if a regulated firm fails its customers, and a tax system that can actually see what is happening. The tone of the British approach has been reform rather than ban, and the result is a market that is harder to access carelessly and a little easier to access sensibly.
