The approval arrives alongside two separate congressional inquiries. Senator Elizabeth Warren is questioning the legal basis for crypto trust charters, while Senator Richard Blumenthal has given four cryptocurrency businesses until January 4, 2027, to voluntarily produce records concerning compliance practices, financial relationships and potential conflicts of interest.
What Does Coinbase’s National Trust Charter Permit?
Coinbase National Trust Company can provide digital asset custody in a fiduciary capacity, primarily serving institutional clients. The federally chartered entity will operate under OCC supervision rather than relying exclusively on the New York state trust framework currently used by Coinbase Custody Trust Company.
According to the OCC’s approval documents, Coinbase plans to migrate its existing custody business to the new national trust company over a three-year period.
The charter does not authorize conventional deposit-taking or commercial lending. Coinbase’s trust company will also not directly provide staking, trading or financing services. Instead, it can connect custody customers with those services through other Coinbase entities.
The authorization carries substantial financial conditions, including a minimum $60 million Tier 1 capital requirement, liquidity safeguards and sufficient eligible liquid assets to cover 180 days of operating expenses during its initial three years.
As FinanceFeeds previously reported, the final approval establishes a federally supervised institutional custody structure without turning Coinbase into a full-service commercial bank.
The distinction matters because the federal charter may simplify Coinbase’s institutional operating framework without granting all the permissions or protections associated with insured deposit-taking institutions.
Investor Takeaway
The charter provides Coinbase with a federally regulated custody structure that could support institutional client relationships. However, the $60 million capital requirement and continuing supervisory obligations create costs, while the approval does not independently authorize lending, stablecoin issuance or broader banking activities.
Why Is Warren Challenging the OCC’s Crypto Charter Decisions?
Senator Elizabeth Warren, the ranking Democrat on the Senate Banking Committee, has challenged the OCC’s approval of at least nine national trust charters for cryptocurrency companies since December 2025.
In a May 18 letter to Comptroller Jonathan Gould, Warren argued that some applicants intend to conduct activities extending beyond the traditional scope of trust companies, potentially allowing crypto businesses to obtain federal banking advantages without assuming the obligations imposed on full-service banks.
The inquiry includes approvals involving Coinbase, Ripple, Circle, Paxos, BitGo and other digital asset businesses.
Warren requested complete charter applications, the OCC’s legal analyses supporting its decisions and communications between agency officials and the White House or members of the Trump family concerning those approvals.
Her concerns, previously examined by FinanceFeeds, center on whether the OCC has applied existing banking law appropriately and whether the resulting structures provide sufficient consumer and financial stability protections.
The OCC takes a different legal position. In Coinbase’s preliminary approval, the regulator explained that fiduciary cryptocurrency custody falls within the permissible operations of a national trust company under federal law.
Warren’s letter does not revoke any charter or establish that the OCC acted unlawfully. It seeks the records needed to examine the agency’s decisions and their statutory justification.
Investor Takeaway
Crypto firms pursuing national trust charters face questions about the legal boundaries of their permitted activities. Congressional scrutiny does not invalidate existing approvals, but challenges to the OCC’s interpretation could affect future applications and the services companies can offer through federally chartered entities.
What Records Does Blumenthal Want From Binance and Tether?
Senator Richard Blumenthal renewed demands on November 5 for documents from Binance, Tether, World Liberty Financial and Fight Fight Fight LLC, the company associated with the Official Trump memecoin.
Blumenthal, currently the ranking Democrat and incoming chairman of the Senate Permanent Subcommittee on Investigations, asked the companies to begin producing records by November 30 and complete voluntary production by January 4, 2027.
The requests cover separate but related investigations involving anti-money-laundering controls, cryptocurrency transactions linked to sanctioned entities, political influence and financial relationships involving Trump-associated businesses.
For Binance, the inquiry includes questions about alleged illicit financial activity and relationships with World Liberty Financial. Binance has disputed allegations concerning sanctions evasion and has maintained that it has strengthened its compliance systems.
Tether faces requests concerning the use of USDT in illicit financial networks and reported financial dealings with Nxum, a consulting business co-founded by former White House digital assets adviser Bo Hines.
Blumenthal has also sought records from World Liberty Financial and Fight Fight Fight LLC concerning foreign investments, ownership arrangements and potential conflicts involving Trump’s cryptocurrency ventures.
The latest requests follow earlier unanswered demands, according to Blumenthal’s office. As FinanceFeeds reported on November 9, the senator warned that failure to cooperate could prompt additional congressional measures.
The inquiries concern allegations and potential conflicts rather than established findings of misconduct by the companies named.
What Happens When the January 4 Deadline Arrives?
Blumenthal’s deadline falls immediately after the new Congress is scheduled to convene on January 3, 2027. His anticipated chairmanship could provide additional investigative authority, including access to formal subpoena procedures under applicable Senate rules.
No new subpoenas have been announced in the November 5 letters. The current requests remain voluntary, and any compulsory document demands would require the appropriate congressional procedures.
The distinction between the OCC charter review and Blumenthal’s investigations is important. Warren is examining regulatory decisions made by a federal banking supervisor, while Blumenthal is seeking company records relating to compliance and financial relationships.
Neither investigation automatically changes Coinbase’s authorization or establishes liability for Binance, Tether or the Trump-linked ventures.
Investor Takeaway
The next milestones are the November 30 document-production deadline and January 4 final deadline. For investors, the material developments will be any disclosed compliance weaknesses, legal challenges to charter approvals or compulsory investigative actions, rather than the congressional requests themselves.
