Ripple's chief technology officer has criticized the Federal Deposit Insurance Corporation's (FDIC) actions against cryptocurrencies, particularly after Coinbase publicly exposed the FDIC's attempts to prevent banks from backing the industry. Recent court filings and industry disclosures have brought attention to the regulator's strategy towards the crypto industry. The new filings show that in 2022, the FDIC advised banks to suspend crypto-related activities due to unresolved regulatory risks. A Coinbase investigation into these actions found that the FDIC blocked Financial Institution Group from providing services to the crypto industry more than 20 times. The findings were revealed through the Vaughn index, which outlines letters exchanged between the FDIC and banks. The documents, some dating back to March 2022, have raised concerns about financial stability, operational security and compliance risks associated with crypto products.
