A correspondent bank and an intermediary bank are not the same thing, even though both can show up in the same international wire. The difference between a correspondent bank and an intermediary bank comes down to the nature of the relationship: a correspondent bank holds accounts for another bank under a long-term contract, while an intermediary bank simply routes funds through a single transaction when the sending and receiving banks lack a direct connection.
What a Correspondent Bank Is
A correspondent bank provides ongoing banking services to another financial institution, called the respondent bank, usually in a different country. The Bank for International Settlements defines the arrangement as one “under which one bank (correspondent) holds deposits owned by other banks (respondents) and provides payment and other services to those respondent banks.”1Bank for International Settlements. CPMI Correspondent Banking Consultative Report The relationship is formalized through a bilateral contract and typically lasts years or decades. It is infrastructure.
The mechanical backbone is a pair of mirrored accounts. The respondent bank holds a “nostro” account (Latin for “ours”) at the correspondent, denominated in the correspondent’s local currency. From the correspondent’s side, that same account is a “vostro” account (“yours”). These accounts let the respondent clear payments, settle foreign exchange trades, and do business in a jurisdiction where it has no branch and no direct link to the local central bank.
The services extend past moving money. Correspondent banks handle cash management, foreign exchange, and trade finance, including letters of credit and documentary collections. A mid-sized bank in Southeast Asia can issue a letter of credit to a European supplier because its correspondent bank in Frankfurt has the local presence to confirm and pay it. Without that arrangement, the smaller bank would have to open its own branch abroad.
What an Intermediary Bank Is
An intermediary bank plays a narrower, transactional role. It appears in a wire transfer when the originating bank’s correspondent cannot reach the beneficiary’s bank directly. The intermediary exists in the payment chain only for the duration of that single transfer, passing the funds from one institution to the next until they arrive.
Picture a small credit union in the United States sending euros to a regional bank in Portugal. The credit union’s correspondent bank in New York handles the dollar-to-euro conversion but has no direct relationship with the Portuguese bank. A larger European bank with connections to both steps in as the intermediary, receives the funds from the New York correspondent, and forwards them to Portugal. Once the payment settles, the intermediary’s role is done.
“Intermediary” describes a function within a specific payment, not a permanent status. A bank that acts as an intermediary on one transfer might be someone else’s correspondent on the next. In the SWIFT messaging standard used for most international wires, the intermediary institution has its own designated field (field 56a) in the payment message, separate from the field identifying the correspondent or account-with institution.2Goldman Sachs Developer. Swift Payments That structural separation in the message itself reflects the functional separation between the two roles.
The Practical Differences at a Glance
Three distinctions do most of the work:
- Duration. A correspondent relationship is a standing contract. An intermediary appears in a single wire and disappears from your payment history when it settles.
- Accounts. Correspondent banks hold nostro/vostro accounts for the respondent. Intermediary banks do not hold accounts on behalf of the sender or receiver; they simply route funds through their own network.
- Scope of service. Correspondent banks provide a menu of services: payments, foreign exchange, trade finance, cash management. Intermediary banks perform one function on one transaction.
One clarification worth stating outright: the two roles are not mutually exclusive. The same institution can be a correspondent to one bank and an intermediary in another bank’s wire on the same day. The label depends on what it is doing, and for whom.
How the Two Roles Show Up in a Wire
Trace a cross-border wire and the difference becomes concrete. In a direct transfer, the originating bank sends the payment message and debits its nostro account at its correspondent, which then credits the beneficiary’s bank through their own account relationship. Two institutions, one handoff, fast settlement.
An indirect transfer adds one or more intermediaries into the chain because that direct link doesn’t exist. The payment hops from the originator to its correspondent, then through the intermediary, and finally to the beneficiary’s bank. Each additional hop adds processing time, chances for error, and fees. If the funds get delayed or lost, tracing them requires cooperation from every institution in the chain rather than just two.
SWIFT’s Global Payments Innovation service assigns a Unique End-to-End Transaction Reference to each payment, which lets banks and their customers follow the transfer from initiation to final credit, including processing times at each stop, the number of intermediaries involved, and the fees each one charged. According to SWIFT, nearly 60 percent of payments processed through this system reach the beneficiary within 30 minutes, and almost 100 percent settle within 24 hours.3Swift. Swift GPI If your bank offers this tracking, ask for it. The visibility alone is worth the request.
Why the Difference Costs You Money
Every intermediary bank in the payment chain charges a processing fee, and those fees come out of what the recipient actually receives. Intermediary charges generally run between $15 and $50 per transaction, depending on the currency, amount, and institution. When a payment passes through two intermediaries, the recipient can lose $30 to $100 before the money even hits their account. A direct correspondent relationship avoids this because no middleman ever touches the funds.
When you initiate an international wire, your bank asks you to choose a fee instruction that decides who absorbs the charges along the way. There are three options:
- OUR: you, the sender, pay all transfer fees. The full amount should reach the beneficiary.
- SHA (shared): you pay your own bank’s outgoing fee, and the recipient absorbs any intermediary or receiving bank charges. This is the most common instruction.
- BEN (beneficiary): the recipient pays everything. All fees are deducted from the transfer amount before delivery, so the recipient gets less than expected.
Choosing OUR sounds like it guarantees full delivery, but intermediary banks sometimes deduct fees anyway, particularly in jurisdictions where the OUR instruction isn’t consistently honored. For payments where the exact amount matters, like a real estate closing or a tuition installment, confirm with your bank whether they can guarantee the full amount will arrive or whether you should send extra to cover possible deductions.
The Compliance Weight Falls on Correspondents
The two roles carry very different regulatory loads, and that is another reason banks (and their customers) care about which is which. Correspondent banking sits squarely in regulators’ crosshairs because the ongoing account relationship creates opportunities to obscure the source or destination of funds over time. Section 312 of the USA PATRIOT Act requires every U.S. financial institution that maintains a correspondent account for a foreign bank to establish a due diligence program with risk-based policies and controls designed to detect and report money laundering.4eCFR. 31 CFR 1010.610 – Due Diligence Programs for Correspondent Accounts for Foreign Financial Institutions
At minimum, the U.S. bank must assess the money laundering risk the foreign bank poses, apply monitoring controls proportional to that risk, and review account activity periodically. Certain categories of foreign banks trigger enhanced due diligence: banks operating under an offshore license, banks in a jurisdiction designated as non-cooperative with international anti-money-laundering standards, and banks in a country flagged by the Treasury Secretary as a money laundering concern.5FFIEC BSA/AML InfoBase. Due Diligence Programs for Correspondent Accounts for Foreign Financial Institutions Enhanced due diligence means the U.S. bank must scrutinize the foreign bank’s own anti-money-laundering program, monitor transactions flowing through the correspondent account, and determine whether the foreign bank itself maintains correspondent accounts for other foreign banks piggybacking on the relationship.
Intermediary banks handle individual payment messages and screen them, but they do not carry the same standing due diligence obligation toward the sender or the ultimate beneficiary that a correspondent carries toward its respondent. That is one reason the compliance cost of maintaining correspondent accounts has climbed. For many large global banks, keeping a correspondent relationship with a smaller foreign bank now costs more than the revenue it generates, driving a trend called de-risking in which major banks terminate relationships they view as too expensive or too risky to monitor. The Bank for International Settlements has flagged de-risking as a concern for financial inclusion because businesses in affected countries lose access to affordable international payment channels.1Bank for International Settlements. CPMI Correspondent Banking Consultative Report
For the sender or receiver of a wire, the takeaway is simpler. When you see a “correspondent bank” on your wire instructions, you are looking at your bank’s ongoing partner abroad. When you see an “intermediary bank,” you are looking at a bank that agreed to pass your money along on this one payment, will take a fee for the trouble, and will not appear on your next transfer unless the same routing gap exists again.
