Key takeaways
- A correspondent bank holds an account for another bank, so that bank can send and receive payments in a currency or country where it has no presence of its own.
- The money doesn't cross the border. Settlement happens in the currency's home country, and messages update account balances along the chain.
- Each bank in the chain runs its own checks and may take a fee. That's why wires arrive short, stall or need extra information.
- The network is shrinking: active correspondents fell about 22% from 2011 to 2019, while payment value and volume kept growing.
The short answer
A correspondent bank holds an account for another bank, so that bank can send and receive payments in a currency or country where it has no presence of its own. As of November 2026, these relationships still sit behind SWIFT wires, and they explain why a wire can arrive short, arrive late or stop for questions.
For a finance team, the practical point is simple: the more banks in the chain, the more fees and checks a payment meets. If you can keep a payment inside one country's system, you take those banks out.
How a payment moves, step by step
A BIS Bulletin from May 2024 gives a clear example. A US manufacturer owes a Korean supplier $100, and the supplier banks only in Korea.
- The manufacturer tells its US bank to pay.
- Its bank pays the correspondent bank. This is a domestic US payment, settled at the Federal Reserve.
- The correspondent credits the account it holds for the Korean bank.
- The Korean bank sees the dollars in that account and credits the supplier in won.
As the BIS points out, no money crosses the border. Settlement happens only in the United States, and messages tell each bank which balance to update. SWIFT carries those messages, so it's a messaging network and doesn't hold or move the money itself.
The same example shows how to avoid the chain. The BIS notes that if the supplier had a US bank account, the two US banks would settle directly through the central bank.
The terms you'll meet
| Term | What it means | Where you'll see it |
|---|---|---|
| Correspondent bank | A bank holding accounts for other banks | A supplier's payment instructions |
| Intermediary bank | A bank a specific payment passes through | The intermediary line on a wire form |
| Nostro account | "Our account" at a foreign bank | Bank statements and treasury reports |
| Vostro account | "Your account," the same account seen by the bank holding it | Bank-to-bank records |
| Corridor | A pair of countries linked by correspondents | BIS and FSB reports |
| Charge bearer | Who pays the fees: OUR, SHA or BEN | The wire form |
The cross-border payments glossary covers more.
Why it costs what it costs
Each bank has to do real work. The BIS says each one must check that the message is complete, that the amount complies with restrictions, that no party is on a sanctions list, and that AML checks pass. These run one after another, with a lot of duplicated effort, and if a problem appears, completed steps have to be unwound.
What you see as a customer:
- Deductions. Wise estimates correspondent fees at $15 to $50 or the equivalent, and says they can be higher. They're taken from the payment unless the sender covers all charges.
- Receiving fees. In the FSB's 2025 survey, receiving-side fees averaged 0.1% to 1.3% of the amount, weighing most on small payments.
- FX margins. Where the receiving provider converts the money, the FSB's global averages were 0.7% to 1.1%.
Here's how deductions show up on a $10,000 invoice paid with the SHA option. The per-bank amounts use Wise's range, and the two-bank row is an illustration.
| Banks deducting | Fee per bank | Payee receives | Short by |
|---|---|---|---|
| None | $0 | $10,000 | $0 |
| One | $15 to $50 | $9,950 to $9,985 | $15 to $50 |
| Two | $15 to $50 | $9,900 to $9,970 | $30 to $100 |
A shortfall this small is expensive in staff time: someone has to chase it, write it off or reissue the invoice. OUR, SHA and BEN covers how to prevent it.
Why the network is shrinking
CPMI data published by the BIS shows active correspondents fell by about 22% from 2011 to 2019, and corridors by about 12%. Over the last year of that period, the value of payments rose about 5% and the volume about 4%. So fewer banks are handling more money.
The later BIS Bulletin confirms that the decline continued through 2022 and was global. It says banks cite compliance risk as the main reason for cutting ties, especially with countries with weaker governance, and that some are leaving corridors because the risk-return trade-off is poor. The Federal Reserve's August 2026 note says North America had the smallest drop in active correspondents from 2011 to 2017, at 9.3%.
If your supplier is in a thinly connected corridor, this affects you directly. Fewer banks means longer chains, more questions, and more risk that a payment stops. A route that worked last year can stop working if a bank leaves the corridor.
What to do about it
| What happens | Likely cause | What to do |
|---|---|---|
| The payment arrives short | A bank deducted a fee under SHA | Use OUR if your bank offers it, or pay locally |
| The payment stops with a request for information | A compliance check at one bank | Give the invoice and the purpose quickly, through your own bank |
| The payment comes back after days | Bad details, or a bank refused it | See why payments get returned |
| You can't see where it is | It's between banks | Ask for the UETR and track the payment |
| Your supplier's bank needs a named correspondent | A thin corridor | Get the correspondent details from the supplier, in writing |
| A corridor stops working | A bank ended the relationship | Ask your bank for another route, or use a different rail |
Before you set up a new supplier in a difficult corridor, send a small test payment. It shows you the real time and the real deduction.
How to take banks out of the chain
Use local account details. If you have details inside the payer's own system, the payment can stay domestic. A US customer pays a US account by ACH or wire, and a European customer pays a euro account by SEPA. Named vs pooled virtual IBANs explains what to check, and wire fees shows the savings on being paid in full.
Use stablecoins where both sides can. A USDC or USDT transfer doesn't go through correspondent banks; the next section explains why. Stablecoin vs SWIFT compares the cost.
Stay with SWIFT where it's the only option. It reaches places other rails don't. Good data and the right charge option solve most problems.
Why a stablecoin transfer has no correspondent chain
A stablecoin payment reaches the payee in minutes, at any hour, with no bank in between to deduct a fee or hold it for questions. A stablecoin is a digital dollar (or euro) that moves between companies in minutes, any day, and can be turned back into money in a bank account. There's no chain because no bank holds an account for another: a USDC transfer changes two balances in one shared public ledger, the blockchain. No nostro needs funding, and no correspondent can leave the corridor. The checks don't disappear, though. They move to the two ends, where the providers converting between bank money and stablecoins check who is paying whom and swap sender and recipient details under the Travel Rule where it applies. Those conversions still run on bank rails, with their own hours and fees. A payment sent to the wrong address can't be recalled, and the payee has to be able to accept stablecoins lawfully where it's based. In a well-served corridor, to a payee who wants a bank transfer, a wire or a local transfer is simpler. Align holds and sends USDC and USDT next to its USD, EUR, GBP and AED balances.
How Align fits
Align gives registered companies named USD, EUR, GBP and AED account details, so customers can pay on local rails rather than through a chain of correspondents where those rails apply. For USD, ACH and wires run through a US banking partner, on request and after its own review, and SWIFT reaches more than 180 countries.
SWIFT payments through Align still pass through correspondent banks, and those banks can still take fees or ask questions. Align isn't a bank, and balances aren't covered by deposit insurance. Your own bank may be all you need if you pay a few suppliers in major currencies and aren't troubled by short payments.

Common questions
- What is a correspondent bank?
- It's a bank that holds accounts for other banks and makes and receives payments for them. A small bank in Korea with no US branch, for example, can hold dollars in an account at a US bank. That US bank is its correspondent.
- What is the difference between a correspondent bank and an intermediary bank?
- People often use the terms for the same thing. A correspondent bank is defined by the account relationship it has with another bank. An intermediary bank is the role any bank plays when a particular payment passes through it on the way to the payee's bank.
- What are nostro and vostro accounts?
- They're two names for the same account, from each side. A bank calls the account it holds at a foreign correspondent its nostro, meaning ours. The correspondent calls that same account a vostro, meaning yours.
- Why did a correspondent bank deduct money from my payment?
- Banks in the chain can take a fee from the amount unless the sender chose to cover all charges. Wise estimates these fees at $15 to $50 or more. If your invoice has to be paid in full, ask the payer to use the OUR charge option.
