Crypto ETNs and ISAs in the UK: What Changed on 6 April 2026

Short answer: As of 6 April 2026, you can no longer buy a crypto ETN inside a UK Stocks and Shares ISA. The Individual Savings Account (Amendment) Regulations 2026 (SI 2026/248) reclassified “UK cryptoasset exchange traded notes” as qualifying investments for the Innovative Finance ISA (IFISA) only. Crypto ETNs bought in a Stocks and Shares ISA between 8 October 2025 and 5 April 2026 can stay there and keep their tax shelter, but no new purchases are allowed. Crypto ETNs remain eligible for SIPPs and for ordinary dealing accounts. In practice, very few platforms offer an IFISA that holds crypto ETNs, so most UK investors today hold them in a general account or a SIPP.

Can you hold a crypto ETN in a Stocks and Shares ISA? #

Not any more, for new purchases. The sequence of rule changes matters, so here it is in order:

So there was a window of roughly six months in which a crypto ETN could go into a Stocks and Shares ISA. That window closed on 5 April 2026. The regulation defines a “UK cryptoasset exchange traded note” as a debt security traded on a venue operated by a UK recognised investment exchange, paying no periodic coupon, whose return tracks an unregulated cryptoasset minus fees. Every crypto ETN on the London Stock Exchange main market fits that definition.

What happens to crypto ETNs already in an ISA? #

They stay. Regulation 7, paragraph 2H of the amended ISA rules says crypto ETNs held in a Stocks and Shares ISA immediately before 6 April 2026 are treated as qualifying investments for as long as they remain held. HMRC’s explanatory page uses the same language: holdings made before 6 April 2026 “can remain within the account”. There is no forced sale and no forced transfer. You can also still sell them inside the ISA. What you cannot do is add to the position or buy a different crypto ETN in that ISA.

Brokers have implemented this literally. Trading 212’s help centre states that from 6 April 2026 “new purchases will not be allowed” and the buy button is disabled for crypto ETNs in ISA accounts, while existing positions can be held or sold. Freetrade stopped ISA purchases even earlier, on 1 April 2026, and still allows them in a general investment account. Hargreaves Lansdown, which opened crypto ETN dealing on 3 September 2026, states plainly that they are not available for Stocks and Shares ISAs or Lifetime ISAs.

Which ISA can hold crypto ETNs now? #

The Innovative Finance ISA. The same regulation that removed crypto ETNs from the stocks and shares component added them to the innovative finance component under regulation 8A. The IFISA shares the overall £20,000 annual ISA allowance and gives the same shelter from Capital Gains Tax and Income Tax.

The practical problem is supply. The IFISA was designed for peer-to-peer loans, and the large investment platforms do not run one. As of April 2026, MoneyWeek reported only one provider, Stratiphy, offering crypto ETNs inside an IFISA, and several trade outlets reported that no mainstream platform had plans to. Treat that as reported rather than settled, but the direction is clear: the IFISA route exists on paper and is thin in practice. Check the current provider list before assuming you can use it.

Is a SIPP still an option? #

Yes. HMRC’s October 2025 policy paper allowed crypto ETNs in registered pension schemes from 8 October 2025, and the April 2026 ISA regulation did not touch pensions. Hargreaves Lansdown’s crypto ETN page states they can be held in a Fund and Share Account or a Self-Invested Personal Pension, and AJ Bell’s product pages list the SIPP as an eligible account. Growth inside a SIPP is free of Capital Gains Tax and Income Tax, and contributions attract tax relief at your marginal rate, but the money is locked until pension age and taxed as income on the way out. Not every SIPP provider permits crypto ETNs, and Freetrade, for one, says it is still reviewing whether to offer them in SIPPs.

What protections apply, and what is missing? #

The FCA classifies crypto ETNs as Restricted Mass Market Investments. Firms must run an appropriateness assessment, categorise you as a restricted, high-net-worth or sophisticated investor, show prescribed risk warnings, apply a 24-hour cooling-off period, and offer no incentives to invest. Hargreaves Lansdown, for example, requires either a restricted-investor declaration (no more than 10% of net assets in high-risk investments) or certified high-net-worth status.

The FCA press release announcing retail access states there is no coverage from the Financial Services Compensation Scheme. If the issuer fails or the product goes to zero, there is no compensation backstop, whichever account you hold it in. The retail ban on crypto derivatives remains in force.

What can UK investors actually buy? #

Only Bitcoin and Ethereum ETNs are on the London Stock Exchange’s retail list as of September 2026. If you want exposure to Solana, XRP or another asset through an ETN, the London route does not exist yet, and the European listings on Xetra or SIX carry no UK ISA or SIPP eligibility.

FAQ #

Can I still buy a crypto ETN in my Stocks and Shares ISA? No. From 6 April 2026 crypto ETNs are not a qualifying investment for the stocks and shares component of an ISA under SI 2026/248.

I bought one in my ISA before April 2026. Do I have to sell? No. Holdings made before 6 April 2026 are grandfathered and keep their ISA status for as long as you hold them. You can sell inside the ISA but cannot add to the position.

Which ISA allows crypto ETNs now? The Innovative Finance ISA. Few platforms offer one that supports crypto ETNs, so check the current provider list.

Are crypto ETNs SIPP-eligible? Yes, in registered pension schemes since 8 October 2025, where the provider allows it. Hargreaves Lansdown and AJ Bell both list the SIPP as an eligible account.

Are crypto ETNs covered by the FSCS? No. The FCA has been explicit that there is no FSCS coverage for these products.

Not financial advice. Capital at risk. ISA and tax rules can change and depend on your personal circumstances. Crypto ETNs track volatile assets and carry issuer risk; you may get back less than you invested. Confirm eligibility with your provider and check current HMRC guidance before investing.
