US OCC proposes branded stablecoin restrictions; bipartisan blockchain bill introduced; UK limits crypto ISAs

The US Office of the Comptroller of the Currency proposed rules to restrict branded stablecoins and ban yield rewards on those tokens. US lawmakers introduced the bipartisan Promoting Innovation in Blockchain Development Act of 2026, designed to shield software developers from criminal prosecution under Section 1960. JPMorgan said crypto markets could receive a significant boost in H2 2026 if the market structure bill passes. UK investors will be unable to buy crypto products in their ISAs from April after HMRC reclassified crypto ETNs to a wrapper that no mainstream platform currently offers.
