Key Takeaways

- • From 6 April 2026, cETNs can no longer be newly purchased within stocks and shares ISAs; they can instead be held in the Innovative Finance ISA (IFISA).
- • Investors who already hold cETNs in stocks and shares ISAs before 6 April 2026 may retain those holdings, according to HMRC.
- • No UK platform currently offering the IFISA is authorized to sell crypto ETNs, and IFISAs carry no Financial Services Compensation Scheme protection.
- • Self-invested personal pensions (SIPPs) became eligible to hold cETNs from October 2025, while HMRC has not announced changes to pension treatment.
Summary
UK retail investors can no longer buy crypto exchange-traded notes within a stocks and shares ISA from 6 April 2026, according to reports citing HMRC. Under the rule change, cETNs will instead be eligible only for the Innovative Finance ISA (IFISA), a product with very limited uptake. Direct ownership of cryptocurrency remains unavailable within any ISA wrapper.
The changes follow a decision by the Financial Conduct Authority in October 2025 to allow retail access to bitcoin and ether cETNs, lifting a four-year ban. Products must be traded on a UK-based or recognized exchange, be physically backed by the underlying cryptocurrency, and hold assets in cold storage with regulated custodians. The FCA continues to restrict retail access to crypto derivatives.
HMRC has confirmed that investors holding cETNs in adult or junior stocks and shares ISAs before 6 April 2026 may keep those positions. SIPPs became eligible to hold cETNs from October 2025, though HMRC has not announced any change to pension treatment.
The IFISA, launched in 2016, accounted for about 0.09% of adult ISA subscriptions in the 2023-24 tax year, down from a 2017-18 peak of 49,000 subscriptions to roughly 13,000. No UK IFISA platform is currently authorized to sell crypto ETNs, and IFISAs lack Financial Services Compensation Scheme protection. Morningstar notes that the move will likely obscure the tax-efficiency benefit for the average retail investor.
