Correspondent banking is the system that lets a bank in one country move money to a bank in another country when the two banks have no direct relationship. Instead of connecting to every bank worldwide, a bank maintains accounts with a small number of "correspondent" banks in major financial centers, and payments hop through that chain to reach their destination. It is the invisible infrastructure behind most SWIFT wire transfers — and the source of much of their cost and delay.
No single bank has a direct account relationship with every other bank on Earth — there are tens of thousands of banks globally. Instead, banks build a network of correspondent relationships: a mid-sized bank in Ghana might hold a USD account with a large US bank, which in turn has relationships with other major banks worldwide. When a payment needs to reach a bank with no direct relationship to the sender's bank, it is routed through one or more correspondents that do have a path to the destination — sometimes called a "nested" correspondent chain.
Say a US bank needs to send USD to a bank in Kenya with no direct USD account at a US institution. The US bank sends the payment to its own correspondent bank (often a large US money-center bank), which forwards it to a correspondent that has a relationship with the Kenyan bank, which then credits the recipient's account. Each hop is a separate SWIFT message and a separate settlement step — and each intermediary can deduct a fee ("lifting fee") before passing the remaining funds along, meaning the sender frequently does not know the exact final amount the recipient will receive.
Every additional hop in the correspondent chain adds processing time — each bank in the chain works within its own business hours and compliance review window — and often an additional fee of $10-25 per intermediary. A transfer that looks like a single wire to the sender may actually pass through two or three banks before reaching the recipient, which is why cross-border SWIFT wires commonly take 2-5 business days and cost $30-80 all-in on a $1,000 transfer, factoring in FX markup as well.
Modern payment rails are built specifically to avoid the correspondent chain. Fintechs like Wise pre-fund local accounts in destination countries and settle transfers locally rather than wiring internationally for each transaction — cutting out intermediary hops entirely. Digital asset rails go further: a USDC transfer on Stellar or Tron settles directly between two blockchain wallets in seconds, with no correspondent banks involved at all. The tradeoff for digital asset rails is that both sender and recipient need an account at an exchange to convert between local currency and stablecoin. RemitRoutes compares the all-in cost of correspondent-banking-based wires against these alternatives for your specific corridor.
A correspondent bank is a financial institution that holds accounts on behalf of another bank and processes transactions for it in a country or currency where the other bank has no direct presence. It acts as the local intermediary that lets a bank effectively operate wherever its correspondent network reaches.
Each bank in the correspondent chain processes the payment during its own business hours, applies its own compliance checks, and often deducts a fee before forwarding the remaining funds. A payment that hops through two or three correspondent banks accumulates delay and cost at every step, which is why cross-border wires commonly take 2-5 business days and cost 3-8% all-in.
In most cases you cannot know in advance — the sending bank chooses the routing, and it can vary transaction to transaction. SWIFT gpi tracking lets some banks show a status update as the payment moves through the chain, but the number of hops and their fees are typically not disclosed upfront.
Providers that pre-fund local accounts in the destination country (like Wise) settle transfers locally instead of wiring internationally each time, avoiding the correspondent chain. Digital asset rails avoid it entirely by settling directly on a blockchain between two exchange accounts. RemitRoutes shows both approaches side by side for your corridor.
