Warren Challenges OCC Crypto Trust Charters as Illegal

Senator Elizabeth Warren has accused the Office of the Comptroller of the Currency (OCC) of violating the National Bank Act by approving at least nine national trust charters for cryptocurrency firms. In a letter sent this week to Comptroller Jonathan Gould, the Massachusetts Democrat argued that the recipients “appear to far exceed the narrow scope of activities permitted by law.” The confrontation tests whether existing banking law can accommodate digital asset custody and settlement without congressional action.

The Statutory Basis for Crypto Trust Charters

The OCC has spent the past year methodically opening federal trust routes for crypto firms. It argues that custody, settlement, and “riskless principal” crypto-asset transactions fall within the business of banking when properly supervised under its existing authority. In December 2025, the agency confirmed that national banks may act as riskless principals in crypto-asset trades so long as positions are matched and not held in inventory. That guidance effectively blessed broker-like intermediation in digital assets under existing law.

Industry advocates portray the trust charter route as a way to bring large-scale digital asset custody and settlement under a uniform federal supervisor. The OCC has now approved at least nine such charters, including conditional approvals for five digital asset firms to operate as uninsured national trust banks focused on custody and settlement instead of deposits or lending.

What the National Bank Act Actually Allows

National trust charters permit banks to engage in fiduciary activities, custody, and settlement. The OCC has argued that crypto custody and riskless principal transactions fall within that scope. Warren counters that the law never contemplated digital assets and that the OCC is effectively rewriting the statute through chartering decisions.

Practical rule: A charter is only as strong as the statutory authority behind it. If Congress later clarifies that crypto activities exceed that authority, existing charters could face legal challenges or revocation.

Warren’s Specific Allegations

Warren framed the issue as a basic question of legality rather than policy discretion. Her letter demands detailed documentation of the legal analyses underpinning each approval and an accounting of how the OCC concluded that these digital asset firms qualify as national trust banks under the National Bank Act.

The senator’s intervention comes months after the OCC issued conditional approvals for five digital asset firms. She questions whether the regulator adhered to all relevant legal provisions during the approval process. Her earlier clashes over high-profile charter bids have already highlighted concerns about the OCC’s independence and the risk that crypto firms could gain banking privileges without commensurate safeguards.

Key points from Warren’s letter

The OCC approved at least nine crypto trust charters.
Recipients appear to exceed the narrow scope of activities permitted by law.
The senator demands documentation of legal analyses for each approval.
She questions whether the regulator adhered to all relevant legal provisions.

How the OCC’s Riskless Principal Argument Holds Up

The OCC’s legal foundation rests on the idea that custody, settlement, and riskless principal crypto-asset transactions fall within the business of banking when properly supervised. The December 2025 guidance explicitly permits national banks to act as riskless principals in crypto trades, meaning they can match buyer and seller without taking inventory risk.

That framework treats crypto custody as analogous to traditional trust activities. The OCC has argued that its existing authority under the National Bank Act covers these functions. Gould has previously insisted that crypto charter reviews are “apolitical and nonpartisan.”

Warren’s letter challenges that interpretation directly. She argues that the activities of these crypto trusts go far beyond what the National Bank Act allows, implying that the OCC is stretching its authority beyond congressional intent.

What Confirms the Regulatory Risk

The regulatory risk escalates if any of the following occur:

The OCC fails to provide satisfactory legal documentation in response to Warren’s letter.

Congress introduces legislation to clarify or restrict the OCC’s authority over crypto charters.

A legal challenge is filed against one of the approved charters, testing the statutory basis in court.

The OCC approves additional crypto trust charters without addressing the legal questions raised.

Each of these events would increase the probability that the current charter framework faces disruption. For firms relying on OCC-chartered custody or settlement services, the uncertainty itself is a risk factor.

Affected Assets and Sectors

The primary exposure is to crypto custody providers, settlement networks, and any digital asset firm that holds or plans to hold a national trust charter. Broader market confidence in federally regulated crypto infrastructure also depends on the outcome.

Crypto custody firms with OCC charters face direct legal exposure.

Settlement networks that rely on riskless principal transactions could see operational changes.

Institutional investors using federally chartered custodians may reassess counterparty risk.

What Would Weaken the Thesis

The regulatory risk would diminish if:

The OCC provides a robust legal defense that satisfies Warren and her allies.

Congress passes legislation explicitly authorizing crypto trust charters, removing statutory ambiguity.

A court ruling upholds the OCC’s interpretation of the National Bank Act.

The OCC limits future charters to narrowly defined activities that clearly fall within existing law.

Any of these outcomes would reduce the probability of charter reversals or legal challenges. For now, the burden is on the OCC to demonstrate that its approvals rest on solid statutory ground.

Bottom line for traders: The legal status of OCC crypto charters is uncertain. Until the OCC provides clear documentation or Congress clarifies the law, firms operating under these charters face elevated regulatory risk. Watch for Warren’s next move and any legislative response.

Next Catalyst: OCC Response and Potential Congressional Action

The immediate catalyst is the OCC’s response to Warren’s letter. If the agency fails to provide satisfactory legal analysis, Warren may escalate with hearings or legislation. A court challenge from a consumer advocacy group or state regulator is also possible.

The Warren-OCC clash is not a policy debate. It is a legal question with concrete consequences for every firm holding or seeking a national trust charter. Until that question is answered, the charters operate under a cloud.
