The U.S. Securities and Exchange Commission (SEC) has granted no-action relief, permitting investment advisers to use state-chartered trust companies for crypto asset custody without enforcement action. This decision, prompted by a request from Simpson Thacher & Bartlett, marks a significant regulatory endorsement for the integration of cryptocurrencies into traditional financial systems. The move is anticipated to stimulate growth in the $7.7 billion crypto custody market, reflecting a broader SEC strategy to encourage institutional adoption and mitigate regulatory uncertainty.
