Most declines are a cost decision. The bank weighs what it will spend supervising a digital-asset account against what that account earns, and these files are expensive to supervise. My view is that the NAICS code absorbs far more attention than it deserves. It routes your application and can drop you into a review queue before anyone reads a word. It will never rescue a file that fails to explain itself.
Part of our guide: Wyoming Crypto LLC.
The short version
- A decline prices monitoring cost against expected revenue. What a bank owes on your account barely changes with the balance.
- Federal supervisors stepped back in 2025. The FDIC rescinded its notification regime and the Federal Reserve withdrew its 2022 letter, so you are meeting one institution’s appetite.
- The NAICS code is a routing signal, scored by onboarding software before a human opens the file.
- A code that misdescribes the business is a misrepresentation to a financial institution, and that is worse than being told no.
- Legibility is what moves a file: documented source of funds, a written forecast of expected activity, and entity records that agree.
What the bank is actually deciding
A bank underwrites an account the way it underwrites anything else: what it costs to run, against what it produces. The cost side runs high here for one reason worth naming plainly. The bank sees the fiat legs of your activity and very little else. Wires to and from an exchange or custodian land in its own systems; on-chain history does not, and seeing it means licensing blockchain analytics and staffing someone to read the output. That is a fixed cost one small account will not cover, before monitoring and screening draw on a compliance team already committed elsewhere.
The supervisory backdrop changed recently, and most writing on this describes the old one. In March 2025 the FDIC rescinded its notification requirement, stating that “FDIC-supervised institutions may engage in permissible crypto-related activities without receiving prior FDIC approval.” The Federal Reserve followed in April 2025, saying it will “monitor banks’ crypto-asset activities through the normal supervisory process.” Executive Order 14331, signed 7 August 2025, directed the federal banking regulators to remove reputation risk from their examination materials and set the standard this way:
“Banking decisions must instead be made on the basis of individualized, objective, and risk-based analyses.”
That is where the constraint now sits. No federal rule directs a bank to refuse you, so a decline tells you about that bank’s capacity and appetite.
What the rules require the bank to know
Underneath appetite sit obligations the bank cannot negotiate away. The Bank Secrecy Act rules live in 31 CFR Chapter X, and two shape nearly every question you will be asked. The first is the customer identification program, which requires risk-based verification procedures:
“The procedures must enable the bank to form a reasonable belief that it knows the true identity of each customer.”
“Reasonable belief” is the operative phrase, and it has to survive an examiner asking how it was formed. Every document request is the bank building that record.
The second is beneficial ownership. Under 31 CFR 1010.230 the bank must identify each individual owning 25 percent or more of a legal entity customer’s equity, plus one individual with significant responsibility to control it. A vague operating agreement stalls at this step, which is one reason to settle manager duties first.
A third question changes everything, and applicants often miss it is being asked. An entity moving digital assets for other people may be a money transmitter, carrying FinCEN registration and state licensing obligations. An entity holding its own assets sits elsewhere. Say which you are, precisely, in the first conversation.
What the NAICS code does
The North American Industry Classification System is a statistical instrument. The Census Bureau maintains it so federal agencies classify establishments consistently when publishing economic data. Nothing in that design contemplates account underwriting.
It reaches underwriting anyway because it is a clean machine-readable field, and onboarding systems score clean fields. A code in a finance or investment family will often route an application into enhanced review before a human opens it. That is the whole of its power. It says nothing about source of funds, counterparties, or expected volume, which are what the review turns on.
Here is where I would push back on most of the advice circulating. Choosing a code because it looks less likely to attract scrutiny is a misrepresentation on an application to a financial institution, and it fails on its own terms. The code that opens the account is the same one that makes a large custodian transfer look anomalous later. A decline costs an afternoon. A closure for cause follows you to the next bank.
The workable approach is ordinary. Describe what the entity does in plain language, find the classification matching it through the Census NAICS search, then make sure that description appears on the EIN record, the state filing, the operating agreement, and the application.
Whether the account is the right ask
Worth settling first: what does the entity need a bank for? A holding company owning assets at a custodian, never converting to dollars, pays the registered agent, the state fee, the CPA, and the custodian’s invoices. That is a low-volume account with predictable outbound payments, and it opens readily where a trading operation would be refused. Size the request to the structure you actually built.
What I actually see
The most common pattern is a one-line answer where a paragraph was needed. The form asks what the business does and the applicant writes “cryptocurrency investment.” Compliance now holds a category and no facts, and declining is the cheapest thing to do with that. Nobody is going to call and invite you to elaborate.
The second is code shopping. A forum suggests a general consulting classification because it reads as less alarming, the account opens without friction, and then a large wire arrives from a custodian into what the file calls a consulting business. That is the transaction that gets escalated, and the record now holds a description the company’s own activity contradicts.
The third is paperwork disagreeing with itself. The EIN record says one thing, the state filing another, the operating agreement a third activity, the application a fourth. Nobody lied. Nobody reconciled them either, and a bank reading four descriptions of one company cannot form the belief the rule requires.
The check I would run before touching any form: write one paragraph covering what the entity does, where its assets came from, what will move in and out over the next year, and who is on the other side. Then ask whether the classification you planned to use fairly summarizes what you wrote. Where the two disagree, the paragraph is the fact and the code is the error. Hand it to the banker, because it is what they have to write anyway.
Where this goes wrong
The failures cluster around descriptions that do not match activity.
Specifically: an application answered in three words, leaving compliance to guess. A classification chosen for how it looks, which turns the first large transfer into an escalation. Source of funds that stops at “I bought it years ago.” An operating agreement never naming who controls the company, so the beneficial ownership check cannot close. Expected activity described as “varies,” which a monitoring team reads as unforecastable. And a personal account paying entity expenses, the same commingling that damages the tax records.
The decision rule
- Settle whether the entity is a money transmitter first, because that drives the licensing question and the bank’s category for you.
- Write the activity paragraph first, then choose the classification that fairly summarizes it.
- Look the code up at the source through the Census NAICS search, never from a forum thread.
- Reconcile the four records. EIN letter, state filing, operating agreement, and application should describe one business.
- Document source of funds back to acquisition, with exchange statements and transfer records, before anyone asks.
- Forecast expected activity in writing: monthly count, typical size, direction, and named counterparties.
- Ask the institution whether it onboards digital-asset entities, and reach the person who owns that answer, rarely the branch.
- Size the account to what the business does, and read a decline as information about that bank’s program.
Where this sits
Banking is the last structural decision, and people leave it until the entity exists. The entity choice determines what you are describing to a bank. Custody determines who can produce statements for the assets, and a titled custody account is the cleanest source-of-funds evidence an applicant can bring. The Wyoming LLC hub covers what comes upstream.
These questions get answered by people who never see each other’s work. The attorney drafts the operating agreement, the CPA picks an activity description for the return, the custodian onboards under its own rules, and the applicant fills in the bank form from memory. Each answer is defensible alone. The bank reads them together, and the join is where it fails.
