Banks vs. OCC: The 2026 Crypto License War

Eleven crypto firms obtained federal banking licenses in 83 days. Now, the largest banks in the United States — JPMorgan, Bank of America, Citi, Wells Fargo — are considering suing the regulator that granted them. What seemed like a quiet victory for the crypto industry in December 2025 has become a trench war by May 2026. The Bank Policy Institute (BPI, the main lobby for big banking) accuses the Office of the Comptroller of the Currency (OCC, the federal regulator for national banks) of opening a channel for "regulatory arbitrage"; Senator Elizabeth Warren has sent a letter accusing the OCC of approving "illegal" licenses under the National Bank Act and demands all records by June 1; and the CLARITY Act, the law intended to bring order to the sector, has been stuck in the Senate for weeks due to pressure from that same lobby. This article does not explain what a national trust charter is — we covered that when Coinbase became a bank on April 2 —; here we break down the counterattack: who is suing whom, with what legal argument, and why the real battlefield is not custody but the money sitting in your checking account.

Why does big banking want to sue the OCC?

The approval of federal trust licenses for crypto firms is not new. What is new — and what lit the fuse — is the speed and volume. Between December 12, 2025, and early March 2026, in an 83-day window, eleven digital asset native and fintech companies applied for or obtained a national trust charter from the OCC: Circle, Ripple, BitGo, Fidelity Digital Assets, Paxos, Bridge (a Stripe subsidiary), Crypto.com, Payoneer, Revolut, Zerohash, and the Trump family's crypto project, World Liberty Financial. Coinbase joined on April 2; Kraken, via its parent company Payward, submitted its application on May 8.

To understand why banks see this as a threat, consider an analogy. Imagine a payment app that for decades has been the only one authorized in a country, subject to strict regulations: capital audits and a common fund that covers users if the company goes bankrupt. Suddenly, the regulator lets in a dozen new apps offering almost the same services, but exempt from paying into the common fund and without those audits. The old players aren't complaining about the competition itself, but that they are competing with half the rules. That is regulatory arbitrage: obtaining the benefits of a license without assuming all its burdens.

The BPI — whose board includes Jamie Dimon (JPMorgan), Brian Moynihan (Bank of America), and David Solomon (Goldman Sachs), and which represents about 40 large banks — argues that the OCC is giving crypto firms a federal seal of approval and access to the core of the dollar payment system without requiring the safeguards a commercial bank must endure. The sharpest legal argument points to the OCC's Interpretive Letter 1176: the lobby alleges it expanded eligibility for licenses without going through the formal "notice and public comment" process required by law for significant changes. As of late May 2026, the lawsuit had not yet been filed — the BPI is weighing the timing with its lawyers — but the threat is public and formal.

What does a traditional bank lose to a licensed crypto firm?

The complaint is not rhetorical: it rests on specific control asymmetries. A full-service commercial bank (BPI members) operates under section 12 U.S.C. 24 of the National Bank Act — it takes deposits, lends, and is required to pay FDIC insurance, comply with Basel III capital requirements, and subject its parent company to Fed oversight. A national trust charter operates under 12 U.S.C. 27(a): its activity is limited to custody, settlement, and fiduciary functions, and most do not have FDIC insurance or grant commercial credit.

Resistance has been channeled through letters of opposition to the OCC signed not only by the BPI, but also by the American Bankers Association (ABA), the Independent Community Bankers of America (ICBA), and the Conference of State Bank Supervisors (CSBS), which represents regulators from all 50 states. The ABA has called for an immediate suspension of new licenses until it is proven that the resolution framework for uninsured trusts (12 CFR Part 51) can liquidate volatile crypto assets without infecting the system. In Crypto.com's application, the BPI demanded guarantees that the entity would not commingle stablecoin reserves with its own accounts; and in the file for Agora — issuer of the AUSD stablecoin — it requested a ban on holding client funds as "synthetic deposits" that function de facto as credit.

What exactly is Elizabeth Warren accusing the OCC of?

The conflict jumped from the corporate to the political arena on May 18, 2026, when Democratic Senator Elizabeth Warren, a high-ranking member of the Senate Banking Committee, sent a formal letter to Comptroller Jonathan Gould. Her thesis: the OCC has systematically violated the National Bank Act by granting trust licenses to companies that do not meet eligibility requirements.

Warren's argument is technical but forceful. Congress, she says, designed national trust companies for a very narrow and strictly fiduciary range of activities — executors, estate administrators — described in section 12 U.S.C. 92a. However, the business plans of the approved crypto firms project brokerage, proprietary trading platforms, staking, and payment gateways. This makes them, she argues, de facto "crypto-banks": they do the work of a full-service bank while dodging the capital, deposit insurance, and consumer protection obligations of real banks. She cited specific cases: the plan for Protego National Digital Trust Company includes custody, trading, a lending platform, and a system for asset issuers; the Coinbase National Trust Company application describes staking, leveraged trade financing, and payment products.

The letter demands the delivery by June 1, 2026, of the full applications and confidential exhibits of the nine approved trusts (Ripple, Paxos, Circle, Fidelity, BitGo, Crypto.com, Protego, Bridge, and Coinbase), the internal legal opinions justifying how trading and staking fit into the National Bank Act, and — the most political point — all communications between the OCC and the White House or the Trump family, with emphasis on the World Liberty Financial file.

The industry responded. The Digital Chamber, representing more than 250 companies in the sector, replied to Comptroller Gould supporting the OCC's legality. Its CEO, Cody Carbone, argued that Warren relies on an outdated reading of the National Bank Act and that the decisions are consistent with the GENIUS Act — the federal stablecoin framework enacted in July 2025 — which sought to give issuers an orderly path for federal supervision.

How is the OCC using the 2026 rule change?

The legal ground on which the battle is fought is a single-sentence amendment. On February 27, 2026, the OCC published a final rule — in effect since April 1 — that modified the licensing regulation (12 CFR 5.20), replacing the limiting term "fiduciary activities" with the formula "the operations of a trust company and activities related thereto."

The change seems minor, but it corrects a 2003 ambiguity. That year, the regulation required a special purpose bank with functions other than "strictly fiduciary" to perform at least one of the three classic banking functions: taking deposits, paying checks, or lending money. Since trusts do not insure deposits or lend, that wording acted as a wall: a national trust could not custody non-fiduciary digital assets. The 2026 amendment aligns the regulation with section 12 U.S.C. 27(a) and makes it clear that the custody of securities and digital assets is a natural part of a trust company's powers. For the industry, it is a clarification of pre-existing authority; for the banks, it is the "back door" that opened the floodgates.

That amendment fits with the GENIUS Act like two pieces of the same mechanism. GENIUS prohibits anyone without one of three licenses from issuing payment stablecoins, and one of them — the Federal Qualified Issuer — falls under OCC supervision and expressly includes uninsured national trust banks. The law requires 1:1 backing in high-quality liquid assets (cash at the Fed, short-term Treasury bills), prohibits rehypothecating those reserves, and — a key piece of the entire war — prohibits paying yield or interest to stablecoin holders. It is this prohibition, and not custody, that explains why banks are fighting so hard.

Why is the real battlefield stablecoin yield?

Here is the heart of the conflict, and almost no one names it. Bitcoin custody doesn't keep JPMorgan awake at night. What does is the possibility of a regulated stablecoin paying interest to its holder. To understand why, you have to look at where a bank's money comes from.

A commercial bank operates on fractional reserve: when you deposit $1,000, it doesn't keep it in a box. It lends most of it out — mortgages, business credit — and keeps a fraction as a reserve. The difference between what it charges for lending and what it pays you for depositing (often almost nothing) is its business, and it depends on one condition: that your money stays still in the account, cheap and available to be lent. A 100% backed stablecoin is the opposite: a full-reserve model, where every token is backed one-to-one by cash or short-term public debt and the issuer does not lend your money. If that stablecoin could pay you the risk-free rate generated by its reserves, it would compete directly with your checking account. Therein lies the fear: if stablecoins yield, the cheap money that finances mortgages flees, fractional reserve banking becomes undercapitalized, and credit contracts. That is the argument with which banks defend the GENIUS yield prohibition.

The problem for the banks is that the White House itself put that argument to the test — and the result does not favor them. On April 8, 2026, the White House Council of Economic Advisers (CEA) published a study titled Effects of Stablecoin Yield Prohibition on Bank Lending that models how much credit the prohibition actually protects and at what cost. The qualitative conclusions are devastating for the lobby:

• Prohibiting stablecoin yield barely increases the banking system's lending capacity: about $2.1 billion in additional credit, or 0.02% of the total economy.
• Of that preserved credit, 76% is captured by large banks; community banks get the remaining 24% (about $500 million, or 0.026% of their portfolio).
• The prohibition imposes a net welfare cost of $800 million per year on the economy by depriving consumers of earning the risk-free rate on their tokenized dollar balances.
• The cost-benefit ratio is 6.6: for every dollar of credit capacity preserved in traditional banking, society loses $6.60 in welfare.

The CEA concluded by noting that the banks' catastrophic scenario — a massive flight of deposits — requires extreme assumptions: that the stablecoin market grows sixfold, that all its reserves are immobilized in cash without buying Treasury bonds, and that the Federal Reserve abandons its liquidity provision scheme. The threat exists on paper, but it requires three planets to align at once. We detail this yield veto in our analysis of the Circle yield ban under the CLARITY Act.

Why has the CLARITY Act been blocked in the Senate for weeks?

All this fighting leads to a law. The CLARITY Act (H.R. 3633), promoted by Congressmen French Hill and G.T. Thompson, seeks to draw the definitive boundary between the SEC and the CFTC through a "mature blockchain test." The House passed it on July 17, 2025, with broad bipartisan support (294 in favor, 134 against), and the Senate Banking Committee moved it forward on May 14, 2026, by a vote of 15 to 9.

But it is stuck on the Senate floor, and the brake is the banking lobby. The BPI and its allies demand that the final version hermetically close the door to structuring deals with subsidiaries or intermediaries that indirectly pass reserve yields to holders. It is not enough to prohibit the stablecoin from paying interest directly; they want to prohibit the workarounds as well. The fight is over a single sentence in the text.

The deadlock drew public criticism from Donald Trump, who accused big banks of hindering national fintech competitiveness to protect their market share. The White House set July 4, 2026, as the deadline, but as of late May, disagreements over yield keep it paralyzed. For vote details, see our summary of the CLARITY Act vote on May 15.

What banking model is being born from this war?

Beyond the legal noise, what is at stake is the shape of the financial system for the next decade. One firm provides clues: the settlement and treasury firm Lorum, which applied for its OCC license on April 9, 2026, with an avowedly full-reserve model. Its critique is precise: fintechs and medium-sized companies must deposit their operating capital in regional banks that use that money — intended for daily payment settlement — to finance long-term mortgages and capture overnight yield. This maturity mismatch immobilizes funds and raises counterparty risk: if the regional bank stumbles, the settlement money is trapped. Lorum eliminates this at the root: 100% backing in cash at the Fed or very short-term public debt, without lending anything, and nominal account custody — each client having a direct relationship with the federal framework, without omnibus accounts nested in intermediaries.

The other milestone pointing in the same direction is Kraken: on March 4, 2026, its Wyoming subsidiary Kraken Financial became the first digital asset native firm to obtain a Federal Reserve Master Account, with direct access to Fedwire without a correspondent bank in between (we analyzed this in Kraken's Master Account at the Fed). Taken together, the two pieces draw a fork in the road: on one side, traditional fractional reserve banking, oriented toward long-term credit; on the other, a federal system of full-reserve trusts, optimized for instant settlement and stable money without counterparty risk. The fundamental question of the entire war is which of the two models will be the axis of the system.

Who wins and who loses in this regulatory battle?

The "trust license fever" has ceased to be a technical formality and has become a restructuring of how the dollar is settled. CleanSky's editorial view is that banks are not fighting against crypto custody — which they control without issue — but against a change in the economics of deposits: if idle money can yield, fractional reserve loses its cheap raw material. Hence the triple offensive: the BPI lawsuit via the judicial route, Warren's letter via the political route, and the CLARITY Act blockage via the legislative route. Three fronts, one goal: to slow down or make the competitor more expensive before the model consolidates.

The outcome is far from decided. The OCC defends its licenses as an exercise of pre-existing authority, backed by GENIUS and its February amendment; the CEA study removes the economic basis for the "credit contagion" argument; and the Trump administration is pushing to pass the CLARITY Act before July 4. Against that, the banking lobby has time, money, and an argument that resonates: these entities use the word "bank" without offering the FDIC insurance that the public associates with it.

The practical conclusion is that the framework regulating stablecoins and federal custody in the U.S. — and by extension, the standard that half the world will copy — is being forged right now in letters, lawsuits, and committee votes, not in technology. Anyone who wants to understand where digital money is going would do well to look at the Senate calendar and the June 1 deadline, not just token prices. Meanwhile, the 1:1 backing required by the GENIUS Act translates into one observable thing: that each stablecoin stays pegged to its dollar. That is exactly what we update every 15 minutes in the CleanSky stablecoin monitor — 14 currencies in USD, EUR, BRL, and SGD — where you can check live if USDC and its competitors are maintaining the parity that this entire regulatory war intends to shield.
