Crypto ETNs in the UK: what changed for retail investors, ISA rules and the risks

For years, UK investors who wanted exposure to bitcoin had two options: buy the crypto itself on an exchange, or do without. Products that track crypto prices on a stock exchange, popular in other countries, were off-limits to retail investors. That changed in October 2025, when the FCA reopened access to crypto exchange traded notes (cETNs).

This guide explains what crypto ETNs are, the rules that come with them, how they fit into ISAs and pensions, and the risks that remain.

What a crypto ETN is

An exchange traded note is a security listed on a stock exchange whose value is linked to something else: here, the price of a cryptoasset such as bitcoin or ether. You buy and sell it through an investment platform or broker, in the same way as a share or fund, during exchange trading hours.

HMRC describes cETNs as debt securities designed to track the performance of the cryptoassets they reference. The FCA says each product’s prospectus has to be reviewed and approved before it can be offered, and that retail investors can only buy cETNs that are on the FCA’s Official List and admitted to trading on a UK Recognised Investment Exchange.

The key difference from owning crypto directly is what you own. With a cETN, you hold a note issued by a company, not the cryptoasset itself. You don’t need a crypto exchange account or a wallet, but you depend on the issuer and the product’s structure. For a comparison with US and Canadian spot funds, see bitcoin ETFs explained.

What changed

• January 2021: the FCA banned the sale, marketing and distribution to retail clients of derivatives and ETNs that reference unregulated transferable cryptoassets.
• June 2025: the FCA announced it would lift the ban on crypto ETNs, saying it wanted to support the growth and competitiveness of the UK’s crypto industry and let people choose whether such a high-risk investment is right for them.
• 8 October 2025: the change came into force. Retail investors can buy cETNs that are on the FCA’s Official List and admitted to trading on a UK Recognised Investment Exchange (RIE).

What didn’t change: the FCA’s ban on retail access to cryptoasset derivatives, such as crypto futures, options and CFDs, remains in place. See leverage and derivatives rules.

The rules that protect you, and the one that doesn’t

The FCA classifies crypto ETNs as Restricted Mass Market Investments. For investors, that means firms must:

• Not offer any incentives to invest, such as bonuses for buying.
• Run appropriateness assessments, checking you understand the product, and apply client categorisation and cooling-off periods.
• Show clear risk warnings.

The Consumer Duty, which requires firms to deliver good outcomes for retail customers, also applies to firms offering cETNs. The FCA spells out what that means for these products. Firms must:

• identify a target market of consumers for each cETN, design it for their needs, and take reasonable steps to make sure it’s distributed to that market;
• make sure the product provides fair value to those consumers;
• give consumers the information they need, at the right time, in a way they can understand;
• act in good faith and avoid causing foreseeable harm.

In practice, expect your platform to ask questions before letting you buy, and to show you risk warnings. Those steps are required, not optional extras.

But there’s one important gap: the FCA says there is no Financial Services Compensation Scheme (FSCS) cover for crypto ETNs. If something goes wrong, you can’t rely on the FSCS to compensate you. See is your crypto insured?

ISAs and pensions

HMRC’s rules for tax wrappers have already changed once, so dates matter:

Two practical points:

• Already in a stocks and shares ISA? HMRC’s March 2026 guidance says cETNs held in a stocks and shares ISA or Junior ISA before 6 April 2026 can remain in the account.
• Fewer providers offer IFISAs. HMRC says ISA managers that don’t already have approval to offer a stocks and shares ISA or an IFISA need to seek it, so check whether your provider offers cETNs in an Innovative Finance ISA before planning around it.

Whether a particular pension accepts cETNs is up to the scheme and its provider.

The ISA allowance still applies

For the 2026 to 2027 tax year, you can put up to £20,000 in total into ISAs, split however you like across cash, stocks and shares, Innovative Finance and Lifetime ISAs. Inside an ISA you pay no tax on income or capital gains from investments, and you don’t need to declare them on a tax return. So a cETN held in an Innovative Finance ISA shares the same £20,000 allowance as everything else you save in ISAs that year.

The government has said it will keep the treatment under review, with a view to allowing cETNs back into stocks and shares ISAs later, as the market matures.

Outside an ISA or a pension, gains on cETNs may be taxable. Check HMRC’s guidance for how your product is treated, or speak to a tax adviser. For tax on crypto you hold directly, see UK crypto tax.

The risks

Lifting the ban didn’t make crypto less risky. The FCA’s own announcement says people could lose all their money. The main risks:

1. Price risk. The note tracks a highly volatile asset. Big moves in a day are normal.
2. Issuer and structure risk. You depend on the issuer and how the product holds or backs the cryptoasset. Read the key information document.
3. No compensation scheme. No FSCS cover if things go wrong.
4. Costs. Annual product charges and platform fees eat into returns over time. Compare them with the costs of buying directly. See exchange fees explained.
5. Trading hours. Crypto trades around the clock, but cETNs only trade when the exchange is open, so prices can gap at the open.

cETN or direct crypto?

If you’d rather hold crypto directly, use a firm registered with the FCA. See how to check if an exchange is registered.
