英国の投資家は、4月6日以降、免税の「株式・株式 ISA」口座に暗号資産取引型証券（ETN）を新たに追加できなくなります。HMRCはこれを「イノベーション・ファイナンス ISA」資産に分類しています。既に保有している者は強制的に売却する必要はなく、今後も政策は継続的に評価される予定です。

The UK will adjust its Individual Savings Account (ISA) policy in April 2026, and retail investors will no longer be able to purchase cryptocurrency exchange-traded notes (ETNs) with ISAs, as they are reclassified as assets that do not meet ISA rules. This change will impact investors' tax planning and asset allocation strategies, especially increasing investment complexity for young investors, and also reflects the cautious attitude of UK regulators.
