The UK Financial Conduct Authority (FCA) has lifted its ban on retail investments in cryptocurrency exchange-traded notes (ETNs). This change allows individual investors to purchase Bitcoin and Ethereum ETNs through regulated platforms. These investments can be held tax-free in Individual Savings Accounts (ISAs) and registered pension accounts. According to the latest policy document from HM Revenue and Customs (HMRC), starting April 6, 2026, crypto ETNs will be reclassified as innovative finance ISA investments, but their tax benefits will remain unchanged.
