Vad Storbritanniens nya regelverk för krypto innebär för investerare

In December 2025, HM Treasury announced what may be the most significant change in UK financial regulation since the post-2008 reforms: a comprehensive framework for cryptoasset firms that places them under the full supervision of the Financial Conduct Authority.

The UK has established a transatlantic working group on digital asset innovation together with the United States, suggesting that British regulators are thinking beyond domestic borders. For investors, this matters because regulatory fragmentation — where the rules diff
