Key takeaways
- An FBO (for benefit of) account is a bank account a company holds on behalf of its users. The money is pooled, and a ledger says who owns what.
- FDIC pass-through insurance can cover each owner separately up to $250,000 per ownership category, but only if the records meet the rules and only if the bank itself fails.
- The Synapse bankruptcy in 2024 showed the risk: no bank failed, yet people couldn't reach their money for months, because the ledger was in doubt.
- If you're a fintech, the ledger is the product. Know who holds it, how often it's reconciled, and what happens to it if a partner fails.
The short answer
An FBO account, short for "for benefit of," is a bank account a company holds on behalf of its users. The company's name is on the account, many users' money sits in it together, and a ledger records who owns what. Modern Treasury describes it as an account that lets a company manage funds on behalf of its users without assuming legal ownership of the account.
FBO accounts are how many US fintechs hold customer money without being a bank. As of November 2026, the main thing to understand about them is this: the bank knows the total, and the ledger knows the owners. Everything that can go wrong is about that gap.
How the structure works
| Layer | What it holds | Who runs it |
|---|---|---|
| FBO account | The pooled cash | The partner bank |
| Virtual accounts | Sub-account numbers for matching payments | The bank or a middleware provider |
| Ledger | Each user's balance | The fintech, the bank or a third party |
| App | What users see | The fintech |
Virtual accounts add convenience, but they don't separate the money. Modern Treasury notes that funds in the pooled account are fungible, with the ledger tracking the balances. For the same question in Europe, see named vs pooled virtual IBANs.
What pass-through insurance really covers
FDIC insurance applies to deposits at insured banks. The FDIC's 2022 advisory says it applies in the event of an insured bank's failure, and that the FDIC doesn't insure assets issued by non-bank entities, such as crypto companies.
For a pooled account, coverage can pass through to each owner. The FDIC's 2024 proposal describes the existing rule: it may rely on records kept by parties other than the failed bank if they're kept in good faith and in the regular course of business. If the requirements are met, each owner's interest is insured separately up to $250,000 per ownership category. If they aren't, the deposit is insured to the person named on the bank's records.
Here's what that means with numbers. Say a fintech holds $3 million in one FBO account for 30 customers, at $100,000 each, and the bank fails.
| Records meet the rules | Records don't | |
|---|---|---|
| Treated as owned by | Each of the 30 customers | The account holder |
| Insured amount | Up to $100,000 for each, so $3 million in total | Up to $250,000 in total |
| Uninsured | $0 | $2,750,000 |
This is a simplified illustration. A customer's other deposits at the same bank in the same category are added together, and a customer with $400,000 in the pool would be insured only up to $250,000.
Now the case that matters more in practice: the bank is fine, but the fintech or its middleware provider fails. Deposit insurance isn't triggered, because no insured bank failed. That's what happened with Synapse.
What Synapse showed
The FDIC's proposal summarizes the case. Synapse, a middleware provider, filed for bankruptcy in late April 2024. In early May, a bank froze deposits linked to Synapse-serviced fintechs after Synapse cut off its access to a key system. Consumers were unable to reach their money for months, a trustee struggled to obtain and reconcile the data, and the FDIC cites more than 1,000 consumer inquiries.
None of the partner banks had failed. The FDIC says the same record problems would likely have slowed a deposit insurance determination if one had.
The FDIC's proposed rule
In September 2024, the FDIC proposed recordkeeping requirements for custodial deposit accounts with transactional features, published in the Federal Register on 2 October 2024. The proposal covers accounts that are set up for beneficial owners, hold their deposits together, and let an owner direct a transfer to a third party. Trust, government, broker-dealer and some other accounts are exempt.
Banks would have to:
- Keep records identifying each beneficial owner, the balance for each owner, and the ownership category.
- Reconcile against those records at least at the close of each business day.
- Where a third party keeps the records, have direct, continuous and unrestricted access to them, even if that third party fails.
We couldn't find a final rule as of November 2026, so treat this as a proposal and check the FDIC's site for its status. Whatever happens to it, it's a sensible checklist for any fintech.
FBO compared with other ways to hold customer money
| FBO account | Account in the customer's own name | Your own money transmitter licenses | |
|---|---|---|---|
| Whose name is on it | The platform, for its users | The customer | The platform |
| Speed to launch | Depends on finding a partner bank | Depends on the provider | Modern Treasury calls licensing time-consuming, varying by state |
| Main risk | Ledger and partner failure | Onboarding effort for each customer | Cost and compliance load |
| Deposit insurance | Possible, on a pass-through basis | Depends on the provider | Depends on where the funds are held |
If your customers are companies moving money abroad, an account in each customer's own name has a further benefit: payers and banks see the right name on the payment, which matters for matching and verification of payee checks.
Questions to ask before you rely on an FBO setup
Fintech teams should get these answered in writing:
- Who keeps the ledger of record: you, the bank or a third party?
- Does the bank have direct, continuous access to it, and would that survive a provider's failure?
- How often is the ledger reconciled to the bank balance, and who signs it off?
- What happens to users' money if you or the middleware provider fails?
- Are funds at one bank or spread across several?
- How is interest handled, and who keeps it?
- What exactly do your marketing pages say about insurance?
Be careful with the last one. What a non-bank says about deposit insurance is a legal question, so have counsel read your wording.
How Align fits
Align isn't a bank. Balances aren't bank deposits and aren't covered by deposit insurance, so don't assume FDIC or any other deposit protection. Is my money safe with Align? explains how balances are held and what isn't covered.
For platforms, AlignConnect offers named account details and payouts through an API, and Align's own customers are registered companies, each with accounts in its own name. If you need insured US deposits for consumers, a partner bank with a well-run FBO structure is a better fit than Align. Align Payments Ltd. is registered with FINTRAC as a money services business (N300000203), and regulated services are provided through licensed financial institutions.

Common questions
- What is an FBO account?
- It's a bank account opened by a company for the benefit of its customers. It's common in fintech: the company's name is on the account, the funds of many customers are pooled inside it, and a separate ledger records how much belongs to each one.
- Are FBO accounts FDIC insured?
- They can be, on a pass-through basis, if the account is at an insured bank and the records meet FDIC rules. Coverage then applies per owner, up to $250,000 per ownership category, if the bank fails. It doesn't cover the failure of a fintech or other non-bank.
- What does FBO mean on a check?
- It means for benefit of. A check payable to a company FBO a named person means that the company receives the money and holds it for that person.
- What's the difference between an FBO account and a virtual account?
- An FBO account is the real, pooled bank account. Virtual accounts are often sub-accounts layered on top of it, each with its own account and routing numbers, so payments can be matched to a user. The funds below remain pooled.
