The U.S. Federal Deposit Insurance Corporation (FDIC) voted on Tuesday to propose tightening rules for third-party deposit intermediaries, according to Bloomberg. The new proposal requires fintech and crypto companies to prove the nature of their business relationships with banks.

Under current rules, intermediaries are exempt from being labeled as depository intermediaries if less than 25% of their total client assets in a specific business line are deposited with insured lenders. The new proposal lowers this threshold to 10%, meaning more intermediaries will need to apply for exemptions.
