HM Revenue & Customs has published amendments to the Individual Savings Account Regulations 2026, effective March 9, 2026. The key changes permit individuals to invest in Long Term Asset Funds within stocks and shares ISAs and Junior ISAs. Additionally, the regulations allow investments in cryptoasset exchange traded notes (cETNs) in a risk-managed manner, and cETNs held in Junior ISAs before April 6, 2026, may remain in the account.

These amendments expand investment options for ISA holders, particularly in emerging asset classes like digital finance. Regulated entities, such as ISA providers, will need to update their systems and product offerings to accommodate these new investment types. While no specific compliance deadline is mentioned beyond the effective date of the regulations, firms should ensure their processes align with the new rules to offer these investment opportunities to their clients.
