Russia's central bank has revised mutual fund investment rules to allow funds aimed at professional investors to invest in settlement indices linked to digital currency quotes. According to ChainCatcher, retail mutual funds may also allocate part of their portfolios to unlisted Russian securities and foreign securities, including tokenized securities and shares of U.S. exchange-traded funds tied to cryptocurrency prices.

The rules set a 10% cap on investments in these assets for retail mutual funds and a 20% cap for closed-end funds.
