Elizabeth Warren, Ranking Member of the U.S. Senate Committee on Banking, Housing, and Urban Affairs, sent a letter to Comptroller of the Currency Jonathan Gould raising concerns about the Office of the Comptroller of the Currency’s approval of national trust charters for crypto companies. Warren argues the approvals allow firms that do not qualify under the National Bank Act to operate like banks without the restrictions, safeguards, and obligations that apply to full-service national banks, creating risks for consumers, the separation of banking and commerce, and banking system safety and soundness. The letter says that since December 2025 the OCC has approved at least nine national trust charters for crypto companies, with several more applications pending. Warren argues many of the applicants’ business plans appear to extend beyond the narrow activities permitted for national trust companies, with no indication that bona fide fiduciary trust activities would be their primary business. Instead, the plans reportedly point to non-fiduciary custody, payments and lending activity, and stablecoin activity closely related to deposit-taking. Warren asked the OCC to provide the full charter applications for the nine approved companies, the legal analyses supporting the decisions, and all communications between OCC officials and the White House or Trump family members regarding the approvals by June 1, 2026.
