An unnamed nationwide financial institution has requested the Workplace of the Comptroller of the Forex for permission to carry crypto by itself steadiness sheet to help blockchain-based companies. On Nov. 18, the OCC lastly answered.
In Interpretive Letter 1186, the company confirmed that nationwide banks could maintain the native property wanted to pay blockchain “community charges,” clearing the best way for regulated establishments to run on-chain operations with out exterior workarounds.
The letter says a nationwide financial institution could pay blockchain “community charges,” generally generally known as fuel, as an exercise “incidental to the enterprise of banking.” It could maintain, as principal, the crypto property wanted to cowl these charges the place it has a “moderately foreseeable” operational want.
That one-sentence clarification simply eliminated the largest operational hurdle dealing with banks that need to custody tokens or transfer stablecoins on public chains: you’ll be able to’t settle transactions on Ethereum in the event you’re not allowed to carry ETH.
The ruling sits between plumbing and precedent. Community charges on public chains are paid within the native asset of the chain. Therefore, any financial institution that wishes to custody tokens, transfer buyer stablecoins, or run tokenized deposits on Ethereum or related networks wants some quantity of ETH or an equal in hand.
Till now, many banks both stayed away from on-chain exercise fully or leaned on third-party suppliers to entrance fuel and wrap it right into a fiat payment.
The OCC is now saying banks can maintain these native tokens themselves as principal in the event that they’re solely wanted to run the pipes.
For big custodians, tokenization desks, and stablecoin issuers working underneath the GENIUS Act framework, that shift means they’ll lastly be full-stack on particular networks with out outsourcing the final lacking piece.
How this connects to GENIUS and the March pivot
The OCC explicitly hyperlinks the letter to actions already allowed underneath the GENIUS Act stablecoin framework.
The company mentioned these actions would require banks to pay community charges “as agent for the client or as a part of its custody operations.”
The letter additionally builds on the broader March-Might 2025 pivot, when the OCC rolled again previous “it’s essential to get prior approval for any crypto exercise” steering and reaffirmed that banks can have interaction in crypto custody, some stablecoin exercise, and participation in distributed-ledger networks with out pre-clearance, topic to straightforward threat administration.
Letter 1186 zooms in on a particular operational snag inside that new framework: you’ll be able to’t do on-chain custody or tokenized deposits in the event you’re not allowed to carry the fuel token.
American Banker quotes the letter’s logic immediately. If serving as a node is permissible, then “accepting the crypto asset community payment” and holding it for some interval should even be acceptable.
In any other case, a financial institution may very well be “virtually barred” from a lawful exercise. That reasoning offers massive custodians a cleaner path to take care of a small fuel steadiness in-house somewhat than farming that perform to fintech intermediaries or staying off-chain altogether.
The identical letter confirms that banks also can maintain restricted quantities of crypto as principal to check in any other case permissible crypto-asset platforms, whether or not constructed in-house or purchased from a 3rd celebration.
In different phrases, the OCC is blessing small, working inventories of native tokens so banks can really transfer transactions on the rails they’re allowed to make use of, and safely take a look at these rails earlier than committing buyer funds or balance-sheet capital to manufacturing deployments.
What adjustments for custody and funds
For funds and settlement, that is about plumbing, not proprietary buying and selling. The change issues most for banks operating stablecoin operations or tokenized deposit packages that choose public chains.
These establishments now have specific authority to carry the fuel wanted to course of buyer transactions with out structuring workarounds or counting on exterior liquidity suppliers.
The steering additionally covers conditions the place the financial institution pays charges on behalf of consumers in its function as custodian or agent, particularly for GENIUS-compliant stablecoins.
A number of summaries stress that holdings are restricted to “operational wants,” together with payment buffers for settlement and for testing custody platforms, not open-ended speculative positions.
That’s the excellence between payment custody and balance-sheet crypto publicity: banks can maintain sufficient ETH to cowl foreseeable transaction volumes and platform testing, however they’ll’t construct a speculative e-book or deal with native tokens as an funding asset.
The OCC’s framing makes clear that is operational stock, not a brand new asset class for financial institution treasuries.
For custody desks, the ruling removes a layer of counterparty threat and operational complexity.
Banks that beforehand relied on third events to supply fuel now have the choice to internalize that perform, which shortens execution timelines and eliminates intermediaries that may themselves face liquidity constraints throughout community congestion or market volatility.
It additionally positions nationwide banks to compete extra immediately with crypto-native custodians which have all the time held native tokens as a part of their service stack.
The constraints banks nonetheless face
The OCC stresses that each one of this have to be finished in a “protected and sound” method and in compliance with current regulation.
The company’s press launch and commentary from the American Bankers Affiliation spotlight that banks should slender the dimensions of those holdings, tie them to particular permissible actions, and run the standard market, liquidity, operational, cyber, and BSA/AML threat frameworks round them.
The OCC solely oversees nationwide banks, whereas the Federal Reserve has, in a separate coverage assertion, continued to explain holding crypto as principal as “unsafe and unsound” for state member banks, creating cross-regulator friction even after the OCC loosened its stance earlier this yr.
That divergence means OCC-chartered banks have the inexperienced gentle to make use of operational fuel balances. Nonetheless, the broader US financial institution universe nonetheless faces blended alerts, relying on constitution sort and first regulator.
Banks may even have to navigate value volatility. Native tokens like ETH fluctuate, which suggests the greenback worth of a financial institution’s fuel stock can swing daily even when the token amount stays fastened.
The OCC’s “moderately foreseeable operational want” customary implies banks ought to measurement buffers conservatively and keep away from holding extra tokens that might expose them to speculative threat.
That creates a balancing act: maintain too little and banks threat operating out of fuel throughout high-congestion intervals. Then again, holding an excessive amount of implies carrying risky property on the steadiness sheet and not using a clear operational justification.
What’s at stake for the business
The broader query Letter 1186 solutions is whether or not US banks can take part in on-chain finance with out regulatory workarounds or structural disadvantages relative to crypto-native opponents.
For years, the implicit reply was no: banks may supply crypto companies solely by staying off-chain, partnering with third events, or looking for case-by-case approval for actions that concerned direct token dealing with.
The March pivot opened the door to custody and stablecoin exercise. This letter removes the final operational blocker by permitting banks to carry the fuel wanted to really settle transactions.
If the stance holds, anticipate nationwide banks with current tokenization or stablecoin packages to convey fuel administration in-house over the following yr.
That shift received’t change the basic economics of on-chain funds. Nonetheless, it should consolidate extra of the service stack inside regulated establishments and scale back reliance on fintech intermediaries for primary settlement features.
It additionally units a precedent for the way regulators would possibly method different operational requirements that require holding native tokens, from staking for proof-of-stake networks to liquidity provisioning for decentralized-finance protocols that banks would possibly ultimately contact.
The danger is that this stays an OCC-only place. If the Fed doesn’t observe swimsuit with related steering for state member banks, the result’s a two-tier system through which constitution selection determines whether or not a financial institution can maintain fuel tokens in any respect.
That might push extra establishments towards nationwide charters for crypto-related companies, concentrating exercise underneath a single regulator and leaving state-chartered banks at a aggressive drawback for on-chain companies.
For now, Letter 1186 is permission, not coverage convergence, and the gap between these two will outline how far US banks can really go.
