OCC Clears Coinbase Trust Charter as Senators Demand Approval Records

The Office of the Comptroller of the Currency has granted Coinbase's national trust company final approval to open, the company announced on Nov. 9, completing a federal chartering process that began with preliminary conditional approval in April. The clearance gives Coinbase's custody business what the company described as a consistent federal framework — a single supervisory standard replacing the patchwork of state-level trust licenses that national custodians have historically navigated.

The approval did not land quietly. Congressional investigators are simultaneously demanding the paperwork behind a wave of crypto trust charters, including Coinbase's own.

What is Congress asking?

On May 18, Sen. Elizabeth Warren sent a letter to the OCC challenging at least nine crypto trust-charter approvals, among them Coinbase's April conditional clearance. The Massachusetts Democrat requested three categories of records:

• the original charter applications;
• the legal analyses regulators used to justify the approvals;
• any related communications between OCC officials and the White House or members of the Trump family.

Warren's inquiry targets the process, not only the outcome. Her letter asks how the OCC used existing authority to expand crypto companies' reach, and whether political contact shaped any of the nine decisions.

A second front from Blumenthal

Four days before Coinbase's Nov. 9 announcement, Sen. Richard Blumenthal renewed records demands aimed at a different set of targets: Binance, Tether and two ventures linked to President Donald Trump. Blumenthal set a deadline of Jan. 4, 2027, for the firms to hand over the requested records voluntarily, and warned that his subcommittee could take further steps to compel production if they do not.

The parallel timing is the story's core tension. Federal regulators are opening more avenues for crypto companies to operate under US rules at the same moment lawmakers are asking whether those avenues were built properly — and whether crypto firms' dealings with people tied to the Trump administration created conflicts of interest.

Why the charter matters commercially

For Coinbase, the operational stakes are concrete. A national trust charter places its custody business under a single federal prudential supervisor rather than a state banking regulator, standardizing capital, audit and fiduciary requirements across jurisdictions. That consistency matters for institutional clients, which typically weigh regulatory standing heavily when selecting a custodian for tokenized assets and fund collateral.

For the broader market, the Coinbase approval signals that the OCC will continue processing crypto trust applications even as Congress scrutinizes the backlog of decisions already made. At least eight other charter recipients beyond Coinbase now sit inside Warren's review perimeter.

What happens next

Two clocks are running. The OCC must decide how much of Warren's requested record — applications, legal memos, White House communications — it can or will disclose, and Blumenthal's Jan. 4, 2027 deadline gives Binance, Tether and the Trump-linked ventures a long runway that ends in potential compulsory process. How the OCC responds to Warren's letter will likely shape whether the crypto trust-charter pathway keeps widening or stalls under congressional review.
