Russia’s central bank has established market-entry procedures for digital custody institutions, cryptocurrency trading platforms and operators of digital rights information systems. The affected firms must register in their respective registries under rules that have been registered with the Russian government and take effect on Oct. 5. The measures add an infrastructure-focused regulatory step alongside the central bank’s earlier revisions to mutual fund rules, which allowed professional-investor funds to use settlement indices tied to digital-currency quotes and permitted limited retail-fund exposure to specified tokenized, foreign and crypto-linked assets.
