The cryptocurrency industry is rallying behind the U.S. Office of the Comptroller of the Currency (OCC) following Senator Elizabeth Warren's criticism of its decision to grant national trust bank charters to firms like Coinbase, Ripple, and Circle. The Digital Chamber of Commerce has sent a letter to Jonathan Gould, Comptroller of the Currency, urging the OCC to maintain its stance. The Chamber argues that the GENIUS Act authorizes the OCC to issue these charters for stablecoin activities, emphasizing that these firms do not engage in traditional banking as they do not accept FDIC-insured deposits. Senator Warren had previously claimed that granting these charters violates the National Bank Act and endangers the U.S. banking system. However, the Digital Chamber contends that the approved companies' operations are distinct from conventional banking, thus aligning with the legal framework established by Congress.
