Federal and state banking regulators have been fighting for years over who has the right to regulate fintechs. The center of this battle has been a series of lawsuits brought against the Office of the Comptroller of the Currency (OCC) by various state banking regulators, including the New York Department of Financial Services. These actions were initiated to prevent the OCC from issuing special purpose national bank charters to non-depository fintech companies and to uninsured deposit-taking fintechs, which would enable the OCC to supervise these fintechs.
