Russia's central bank has amended mutual fund regulations to allow professional investor funds to invest in settlement indices linked to digital currency quotes. The regulatory update expands permissible assets for qualified market participants within the country's collective investment framework. Retail mutual funds may now allocate up to 10% of their portfolio to unlisted Russian securities and foreign assets, including tokenized securities and U.S. exchange-traded funds tied to cryptocurrency prices. Closed-end funds face a higher allocation cap of 20% for these asset classes under the revised rules.
