Stratiphy Launches UK IFISA Platform for Tax‑Free Crypto ETNs After HMRC Rule Shift

HMRC updated its guidance at the start of the 2026‑27 tax year, stating that crypto exchange‑traded notes must be held in an Innovative Finance ISA (IFISA) to retain tax‑free status. Previously, investors could place these ETNs in a Stocks and Shares ISA. The change left a gap: no UK platform combined crypto ETN trading with IFISA administration. Crypto ETNs are debt securities that track the price of underlying digital assets without granting direct ownership, allowing investors to gain exposure through a regulated wrapper.

Stratiphy’s platform will list three 21Shares‑issued ETNs: ABTC (Bitcoin), AETH (Ethereum) and ABGC (Bitcoin‑gold blend). As of September 2025, Bitcoin’s market cap stands at $560 billion, Ethereum’s at $220 billion, and the global crypto ETN assets under management total roughly $4.2 billion. Year‑to‑date, ABTC has risen 12 %, AETH 8 % and ABGC is flat. The IFISA wrapper shelters any capital gains or income from these ETNs from UK income and capital gains tax, provided the assets remain within the ISA.

The launch reopens a tax‑efficient route for retail investors seeking Bitcoin and Ethereum exposure while complying with the new HMRC rule. By bundling ETN trading and IFISA management, Stratiphy reduces operational friction and may attract inflows from investors who previously exited crypto ETNs due to tax inefficiency. Market participants will monitor uptake metrics, the potential addition of other crypto‑linked ETNs, and any further HMRC clarification on IFISA eligibility.
