United Kingdom vs Japan
Crypto regulation comparison
United Kingdom
Japan
The UK has an evolving and increasingly comprehensive crypto regulatory framework. The FCA registers crypto firms for AML/CFT compliance and has imposed strict financial promotion rules requiring risk warnings and banning incentives. HMRC treats crypto as property subject to Capital Gains Tax (10% basic rate, 20% higher rate, with £3,000 annual exemption from 2024/25). The Financial Services and Markets Act 2023 brought crypto assets into the UK regulatory perimeter, and HM Treasury is developing rules for a full crypto regime including exchange licensing, stablecoin regulation, and a potential UK CBDC ('Britcoin').
Japan is one of the world's most comprehensively regulated crypto markets. The Payment Services Act and Financial Instruments and Exchange Act govern crypto exchanges and tokens. Japan classifies crypto as "crypto-assets" and taxes gains as miscellaneous income at rates up to 55%, though reforms to lower this rate are under active discussion.
