Flow of Fundsby Fintech North

How a cross-border wire actually works

A cross-border wire moves money by debiting and crediting a chain of bank accounts that banks hold with each other, while SWIFT carries the instructions that tell each bank what to do.

Smart non-experts new to payments: founders, ops, product, and BD who need to understand why an international wire takes days and loses money along the way.

When you send an international wire, your bank rarely has a direct relationship with the beneficiary's bank. Instead it routes the payment through one or more correspondent banks where each side holds accounts with the other (nostro/vostro). SWIFT carries the messages that instruct each hop; the actual money moves by debiting one account and crediting the next down the chain. FX conversion, per-hop fees, and time-zone cutoffs are why a wire can take one to several business days.

How it moves, step by step

  1. 1
    messageSender

    The sender gives their bank the payment details: beneficiary name, account/IBAN, the beneficiary bank's BIC, amount, and currency.

  2. 2
    messageSender's bank

    The sender's bank works out a route. If it has no direct relationship with the beneficiary's bank, it picks one or more correspondent banks that can bridge the gap.

  3. 3
    moneySender's bank

    The bank debits the sender's account for the amount plus its fee. No money has crossed a border yet; this is a local debit.

  4. 4
    messageSender's bank

    The bank sends a SWIFT payment instruction (an ISO 20022 message called a pacs.008, which replaced the old MT103 in November 2025) to the first correspondent. SWIFT carries the instruction, not the funds.

  5. 5
    moneyCorrespondent bank(s)

    Each hop settles by moving money between the accounts the two banks hold with each other: one bank's nostro account is debited and the counterparty's account is credited, and so on down the chain.

  6. 6
    moneyCorrespondent bank(s)

    If the currency changes, a bank in the chain converts it at its own FX rate and typically takes a margin. Intermediaries may also deduct their own fees, so the amount can shrink at each hop.

  7. 7
    messageBeneficiary's bank

    The final SWIFT message reaches the beneficiary's bank telling it how much to credit and to whom.

  8. 8
    moneyBeneficiary's bank

    The beneficiary's bank credits the beneficiary's account, often after compliance and sanctions screening. The payment is final once this credit is made and any holds clear.

  9. 9
    exceptionBeneficiary's bank

    If a name, account, or compliance detail looks wrong, a bank in the chain can hold the payment for investigation or return it, which adds days and sometimes more fees.

When it’s final

Often one to several business days. Each correspondent hop settles on its own schedule, and time-zone cutoffs plus weekends and holidays in any country along the route can pause the chain. Modern tracking (such as SWIFT gpi) has shortened many wires, but speed still depends on the route, currencies, and screening involved.

Common misconceptions

  • Myth: SWIFT sends the money internationally.

    Reality: SWIFT is a secure messaging network. It carries the instructions that tell banks what to do; the money itself moves through correspondent accounts that banks hold with each other.

  • Myth: The amount you send is exactly what the beneficiary receives.

    Reality: Intermediary banks can deduct fees and apply their own FX margin along the way, so the beneficiary may receive less than the sent amount unless fees are pre-arranged.

  • Myth: A wire is instant because it's electronic.

    Reality: Electronic doesn't mean instant. Each hop settles separately and is subject to cutoff times and compliance checks, which is why cross-border wires commonly take days.
