The crypto industry is pushing back strongly against Senator Elizabeth Warren after she criticized the Office of the Comptroller of the Currency (OCC) for approving national trust bank charters for several digital asset companies.
On Tuesday, industry advocacy group The Digital Chamber (TDC) sent a formal response letter to OCC Comptroller Jonathan Gould, defending the regulator’s actions and arguing that the approvals were fully lawful, carefully reviewed, and necessary for integrating digital assets into the regulated financial system.
Warren Questions OCC Crypto Charter Approvals
The dispute began after Warren sent a letter earlier this month questioning the OCC’s decision to approve national trust charters for multiple crypto-related firms.
According to Warren, some of the companies that received these charters appear to be operating beyond the narrow activities traditionally allowed under US banking law.
The senator argued that at least nine crypto companies may have received approvals that potentially exceed the legal boundaries established under the National Bank Act.
Warren also suggested that the OCC’s decisions could represent an “apparent violation” of federal banking law.
Her concerns reflect a broader skepticism toward the crypto industry and ongoing worries about the risks digital asset firms could pose to the traditional financial system.
The Digital Chamber Defends OCC Decisions
The Digital Chamber strongly rejected Warren’s claims.
In its response, the organization argued that the OCC’s charter approvals were not rushed or politically motivated, but instead followed detailed regulatory reviews and strict supervisory procedures.
According to TDC, every company that received a charter or conditional approval had to demonstrate that its proposed business activities fit within the legal framework allowed for national trust banks.
The group stated that these approvals represent an important step toward bringing crypto companies into a fully regulated federal oversight structure focused on:
- Safety
- Compliance
- Financial stability
- Consumer protection
TDC also argued that Warren’s interpretation misunderstands both the National Bank Act and the OCC’s long-established authority to issue specialized trust bank charters.
Crypto Industry Wants Federal Integration, Not Isolation
The Digital Chamber emphasized that regulated crypto banks should not be viewed as threats to the US banking system.
Instead, the organization described them as federally supervised financial institutions operating under OCC oversight and compliance standards.
According to TDC, integrating digital asset companies into the federal regulatory framework is actually safer than leaving parts of the industry operating outside formal supervision.
The group also stated that it remains ready to work with:
- The OCC
- Congress
- Federal regulators
- Industry stakeholders
to help build a digital asset framework that is both legally durable and operationally effective.
Debate Over Crypto Banking Continues Growing
The dispute highlights the broader battle unfolding in Washington over how crypto firms should interact with the traditional banking system.
Supporters of crypto banking charters argue that regulated integration improves transparency, accountability, and consumer protections.
Critics like Warren, however, worry that expanding crypto access within federally chartered banking structures could introduce new financial risks or weaken existing banking safeguards.
As regulators continue shaping crypto policy in the United States, the debate over OCC trust charters is becoming a major flashpoint in the broader struggle between stricter regulation and industry integration.
For the crypto industry, securing federal oversight and recognition through agencies like the OCC is increasingly viewed as a critical step toward long-term legitimacy and institutional adoption.
