According to disclosed documents, the Federal Deposit Insurance Corporation (FDIC), one of the regulatory banking institutions in the United States, warned the banking industry to stop providing banking services to cryptocurrency operators in 2022 and 2023. The relevant documents were requested to be made public by lawyers representing the cryptocurrency trading platform Coinbase, who are currently in litigation with the FDIC. After the judge approved the request, the FDIC publicly released a redacted version of the document last month, which involved warnings to some banks to stop providing banking services to cryptocurrency operators. It is reported that the original plaintiff's lawyer later requested that the judge order the FDIC to release a more detailed version. The FDIC released the relevant version and an internal notice from 2022 on Friday, instructing regulatory staff on how to evaluate direct processing of virtual currency assets by borrowers and transactions with cryptocurrency companies. Coinbase's legal advisor, Paul Grewel, stated that the content of the documents proves that the FDIC intends to block cryptocurrency companies and prevent them from using traditional banking services.
