"The OCC traditionally charters full-service institutions — those that have deposit insurance," Comptroller of the Currency Thomas Curry said during a Wall Street Journal conference. "But we certainly have a tradition and legal authority to have limited-purpose banks." "The best examples are limited-purpose trust companies that don't have deposit insurance, and credit card banks." The agency is currently evaluating its statutory right to extend the same type of modified charter to fintech companies. Curry said it "probably" has the authority to offer a charter to "something that is a not deposit-taking entity."
