The Office of the Comptroller of the Currency has become crypto's quiet regulatory patron, granting or advancing federal banking charters to some of the industry's most prominent names — Ripple, Coinbase, and a handful of others seeking the legitimacy that comes with a national bank license. Senator Elizabeth Warren believes this represents a dangerous expansion of executive power, calling the charters "unlawful" in a letter that landed with predictable force on Capitol Hill last week. The crypto industry, for once, has responded with something resembling unity.
The defense mounted by digital-asset firms and their lobbyists is notable less for its legal arguments than for its political sophistication. Rather than dismissing Warren's concerns as anti-crypto bias — the reflexive posture of years past — industry representatives are engaging on procedural grounds, arguing that the OCC's chartering authority has existed since the National Bank Act of 1863 and that applying it to new business models is evolution, not revolution.
The charter question
At issue is whether the OCC can grant "special purpose" national bank charters to companies that do not take traditional deposits but instead custody digital assets, facilitate crypto payments, or issue stablecoins. The agency began exploring this territory under the first Trump administration, paused during the Biden years, and has accelerated its work since 2025. Ripple's pending application is the most advanced, but Coinbase and several smaller players have also engaged with the process.
Warren's objection is straightforward: Congress never authorized the OCC to charter crypto banks, and doing so without explicit legislation circumvents the democratic process. Her letter invokes the "major questions doctrine" that the Supreme Court has used to strike down agency actions on issues of vast economic and political significance — a legal theory that has found favor with conservative justices but that crypto firms argue does not apply here.
Industry alignment
The response from the Blockchain Association, the Chamber of Digital Commerce, and individual companies has been unusually coordinated. Talking points emphasize that OCC oversight would subject crypto firms to rigorous federal supervision — capital requirements, anti-money-laundering obligations, regular examinations — rather than the patchwork of state licenses that currently governs much of the industry. The argument, in essence, is that Warren should welcome more regulation, not less.
This framing is clever but incomplete. A national bank charter also preempts state law, potentially freeing charter holders from the consumer-protection regimes that states like New York have built over the past decade. Warren's office has noted this preemption concern, though it has received less attention than the constitutional questions.
Our take
Warren is not wrong that the OCC is pushing boundaries, nor is the industry wrong that federal supervision beats the current regulatory vacuum. The honest answer is that Congress should decide — and has conspicuously failed to do so for a decade. In that legislative void, agencies improvise and industries lobby. The OCC charter fight is less a legal dispute than a symptom of Washington's inability to write coherent crypto policy. Until that changes, expect more letters, more lobbying, and more uncertainty for firms trying to build durable businesses on shifting regulatory sand.
