BitGo CEO Defends OCC Trust Charter as ‘Solution, Not Threat’ in Letter to Senator Warren

BitGo CEO Mike Belshe has directly challenged Senator Elizabeth Warren’s characterization of trust bank charters granted to cryptocurrency firms, arguing in a public letter that such oversight is a protective measure rather than a regulatory loophole. The letter, dated May 19, responds to Warren’s earlier criticism of the Office of the Comptroller of the Currency (OCC) for approving trust charters for digital asset custodians.

The Core Disagreement: What Is a ‘Crypto Bank’?

In his letter, Belshe took issue with Warren’s use of the term “crypto bank,” calling it a rhetorical label with no legal standing. He emphasized that BitGo operates as a qualified custodian, not a depository bank. Unlike traditional banks that lend out customer deposits under a fractional reserve model, BitGo holds client assets on a one-to-one basis under a fiduciary duty. Belshe argued that applying deposit insurance and capital requirements designed for fractional reserve banking to a custodial model is akin to “requiring someone who only rides the bus to have car insurance.”

The distinction is central to the ongoing regulatory debate. Warren had previously expressed concern that the OCC’s trust charter approvals could circumvent banking laws and expose consumers to risk. Belshe countered that the very structure of a trust charter—which mandates strict segregation of assets and prohibits lending or co-mingling—reduces the risk of consumer harm.

Historical Context: Lessons from FTX, Celsius, and Voyager

Belshe pointed to recent high-profile collapses in the crypto sector, including FTX, Celsius, and Voyager, as evidence that the absence of fiduciary duty—not the presence of a trust charter—led to consumer losses. All three firms operated without a fiduciary obligation to safeguard client assets separately. “The trust bank charter is the solution, not the threat,” Belshe concluded, positioning regulated custody as a safeguard against the very abuses that have eroded trust in the industry.

Why This Matters for the Broader Regulatory Landscape

The exchange between Belshe and Warren reflects a wider tension in U.S. financial regulation. The OCC’s willingness to grant trust charters to crypto firms has been seen by some as a pragmatic step toward bringing digital assets under existing banking oversight, while critics argue it creates a parallel system with weaker protections. Belshe’s letter attempts to reframe the debate by arguing that trust charters offer a tailored regulatory framework for custody, distinct from traditional banking, and that conflating the two risks imposing inappropriate rules that could stifle innovation without enhancing consumer safety.

For investors and industry participants, the outcome of this regulatory tug-of-war could shape how digital assets are held and managed in the United States. Clear, consistent rules for custodians may provide the legal certainty needed for broader institutional adoption.

Conclusion

Mike Belshe’s open letter to Senator Warren represents a direct and detailed rebuttal of claims that OCC trust charters for crypto firms are a regulatory end-run. By drawing a clear line between custodial and depository banking, and citing recent failures as cautionary tales, Belshe argues that regulated custody—not its absence—is the path to consumer protection. The debate underscores the need for nuanced regulation that distinguishes between different types of financial services in the digital asset space.

FAQs

Q1: What is the difference between a trust bank charter and a traditional bank charter?
A trust bank charter allows a company to act as a custodian of assets under a fiduciary duty, meaning it must hold client assets separately and cannot lend them out. Traditional bank charters allow depository institutions to lend customer deposits under a fractional reserve model.

Q2: Why did Senator Warren criticize the OCC’s trust charters for crypto firms?
Senator Warren expressed concern that the OCC’s approvals could allow crypto firms to operate like banks without the same level of consumer protection, such as deposit insurance and capital requirements, potentially exposing customers to risk.

Q3: How does BitGo’s business model differ from that of FTX or Celsius?
BitGo operates as a qualified custodian, holding client assets on a one-to-one basis without lending or co-mingling. FTX, Celsius, and Voyager lacked such fiduciary duties, which Belshe argues contributed to their failures and consumer losses.
