Correspondent Banking

TL;DR

Correspondent banking is the arrangement that lets one bank make payments and hold deposits in a currency or jurisdiction it does not directly access, by using another bank (the correspondent) as its access point. The two banks settle through nostro accounts (the respondent’s account at the correspondent) and vostro accounts (the same account, viewed from the correspondent’s side). Almost every cross-border bank wire routes through at least one correspondent, and each correspondent in the chain typically deducts a lifting fee and may apply an FX margin. Correspondent banking carries significant AML risk and is governed in the US by the Bank Secrecy Act (31 USC 5318(i), https://www.law.cornell.edu/uscode/text/31/5318) and globally by FATF guidance (https://www.fatf-gafi.org/en/topics/correspondent-banking.html).

What Is Correspondent Banking?

Correspondent banking is the institutional arrangement under which one bank (the correspondent) holds deposits, makes payments, and provides other financial services for another bank (the respondent). The most common reason is cross-border payments. A bank that wants to settle a payment in a foreign currency, or to a beneficiary in a country where it does not maintain its own branch, opens an account with a bank that does. That account becomes the operational link.

Correspondent banking is the connective tissue of the international payments system. The Federal Reserve has written extensively on its function and on the stresses it has come under in the past decade (https://www.federalreserve.gov/econres/notes/feds-notes/the-stress-on-correspondent-banking.htm). Almost every SWIFT-messaged cross-border wire is settled across a correspondent chain.

Nostro and Vostro Accounts

The two terms most associated with correspondent banking are nostro and vostro. They describe the same account from opposite sides.

• Nostro account. From Bank A’s point of view, the account Bank A holds at Bank B in Bank B’s local currency. Latin nostro means “ours” (as in “our account with you”). A US bank that wants to settle euro payments opens a nostro EUR account at a European correspondent.
• Vostro account. From Bank B’s point of view, the same account. Latin vostro means “yours” (as in “your account with us”). The European correspondent records the US bank’s EUR balance as a vostro account.

When the US bank instructs a EUR payment, its EUR balance at the European correspondent is debited, and the correspondent credits the beneficiary or routes the funds onward to another correspondent if it does not bank the beneficiary directly. The mirror entries net out across the global ledger.

How Multi-Hop Chains Form

Few banks hold direct correspondent relationships in every currency and country. A US community bank wiring USD to a beneficiary in Bangladesh does not typically have a Bangladeshi correspondent. The payment routes:

1. US community bank to large US money-centre bank (which has the global correspondent network).
2. US money-centre bank to a regional correspondent in Singapore, Dubai, or another hub with Bangladeshi banking ties.
3. Regional correspondent to the Bangladeshi beneficiary bank.
4. Bangladeshi beneficiary bank credits the beneficiary’s account.

Each leg in the chain is messaged over SWIFT (now in ISO 20022 pacs.008 format after the November 2025 CBPR+ migration) and settled across nostro and vostro accounts. Each intermediary correspondent typically deducts a fee.

Intermediary Fee Structure

The fee structure on a cross-border correspondent-routed payment has several layers:

• Origination fee. The sender’s bank charges a retail wire fee, commonly $15 to $50.
• Lifting fees. Each intermediary correspondent in the chain typically deducts a fee from the payment amount, commonly $10 to $30 per leg, though it varies widely by bank and corridor.
• FX margin. Where a currency conversion happens at a leg, the correspondent applies an FX margin away from the live mid-market rate, commonly 0.5 to 2 percent on major corridors and higher on exotic currencies.
• Beneficiary credit fee. The receiving bank often charges an inbound credit fee, commonly $5 to $25.

The combined effect is that a nominal $1,000 USD payment can land with $30 to $80 less in nominal value plus an FX margin of 1 to 4 percent on the converted amount. SWIFT’s CBPR+ ISO 20022 messaging exposes more of this detail in structured charge-bearer and remittance fields than the legacy MT103 format did.

AML Risk and Regulatory Treatment

Correspondent banking enables a correspondent to give indirect access to its payment infrastructure to the respondent’s customers, whom the correspondent does not know directly. If the respondent’s KYC and AML controls are weak, the correspondent can process payments for sanctioned parties, politically exposed persons, or money launderers without direct visibility.

The Financial Action Task Force (FATF) treats correspondent banking as a higher-risk activity and has published detailed guidance (https://www.fatf-gafi.org/en/topics/correspondent-banking.html). The Basel Committee has issued parallel guidance on customer due diligence. In the United States, the Bank Secrecy Act at 31 USC 5318(i) (https://www.law.cornell.edu/uscode/text/31/5318) imposes specific due-diligence requirements on US banks maintaining correspondent accounts for foreign financial institutions, including enhanced due diligence on accounts maintained for foreign banks operating under offshore banking licences or in jurisdictions identified as having weak AML regimes.

These compliance costs, combined with reputational risk after several high-profile AML enforcement actions, have driven large global banks to de-risk correspondent relationships with smaller banks in higher-risk jurisdictions. The contraction has been documented by FATF, the Financial Stability Board, and the World Bank. The practical effect is fewer direct corridors, more multi-hop routing, higher fees, and slower settlement on affected corridors.

How Omnivoo Helps

Omnivoo’s Contract Management cross-border payout flow surfaces the correspondent routing detail at origination, including the expected number of hops, the all-in lifting and FX cost, and the SWIFT BIC of each correspondent in the chain on supported corridors. Finance teams see the real landed cost before approval rather than discovering it on the reconciliation side, and a UETR is attached to every supported payment for end-to-end tracking.
