Remit Definition: How Banks Process International Payments

Most traditional banks do not actually move physical cash across borders. Instead, they use electronic messaging systems to update ledgers between institutions.

The SWIFT Network

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the backbone of international banking, connecting over 11,000 financial institutions globally [2]. When you initiate a “remit” instruction, your bank sends a SWIFT message (such as an MT103) to the destination bank.

It is important to note that SWIFT is a messaging system, not a settlement system. It tells the receiving bank that money is coming and provides the instructions, but the actual value moves through a chain of correspondent banks.

Correspondent Banking: The “Chain” Effect

If your bank doesn’t have a direct relationship with the recipient’s bank in, for example, Singapore or Brazil, it must use an intermediary. According to Airwallex, a single international payment can pass through up to four intermediary banks before reaching its destination [2]. Each bank in this chain typically charges a fee—often between $10 and $25—which can result in the recipient receiving significantly less than the original sent amount.

When you “remit” funds through a traditional bank branch or online portal, the transaction follows a standardized lifecycle:

1. Initiation and Instruction: The sender provides the recipient’s name, IBAN (International Bank Account Number) or SWIFT/BIC code, and the currency.
2. Verification and Funding: The bank verifies that the sender has sufficient funds and performs an initial fraud check [3].
3. Compliance Scrubting: This is a critical stage where banks check the transaction against global sanctions lists. As detailed in our Deep Dive into Anti-Money Laundering Practices in International Banks, institutions must ensure they aren’t inadvertently facilitating illegal activity.
4. Currency Conversion: If the sender is paying in USD and the recipient needs EUR, the bank performs the exchange. Banks usually charge a “spread”—a markup on the mid-market exchange rate—which functions as a hidden fee.
5. Settlement: Intermediary banks settle the funds via nostro and vostro accounts (accounts held by one bank for another).
6. Final Credit: The receiving bank accepts the funds and credits the recipient’s account. This typically takes 1 to 5 business days [1].

While domestic transfers are often near-instant, international remittances face several friction points:

• Intermediary Fees: As mentioned, each “hop” in the correspondent banking network extracts a toll.

• Time Zone Differences: Since settlement often requires banks in both countries to be open, a Friday afternoon transfer might not even begin processing until Monday morning.

• Regulatory Friction: Cross-border payments are subject to the laws of both the sending and receiving jurisdictions. This requires extensive “Know Your Customer” (KYC) data [4].

• Legacy Systems: Many banks still rely on infrastructure built in the 1970s. However, the industry is shifting. You can read more about modern updates in our article on The Future of Financial Transactions: Contactless and Mobile Payments.

According to data from Alchemy, the average cost of a cross-border payment can be as high as 6.5% once all fees and exchange rate markups are factored in [5].

For frequent travelers or expatriates, choosing a bank with a robust international presence can reduce these headaches. Some institutions offer “Global Transfers” between their own branches that bypass the SWIFT network’s intermediaries entirely. For recommendations on these types of accounts, see our guide on popular banks for international travelers.

• Remit Defined: In banking, it refers to the intentional transfer of funds across borders to settle a debt or send money to individuals.

• Infrastructure: Most banks use the SWIFT messaging network, which relies on a chain of correspondent banks to move actual value.

• Cost Drivers: Expenses come from outgoing/incoming wire fees ($20-$50), intermediary bank fees ($10-$25 each), and currency exchange markups (1-3%).

• Timeline: Domestic wires are same-day; international remittances take 1 to 5 business days due to time zones and compliance checks.

• Irrevocability: Once a wire transfer is accepted by the receiving bank, it is generally impossible to reverse [1].

Action Plan

1. Compare Rates: Always check the “mid-market” rate on Google before agreeing to a bank’s exchange rate.
2. Use Local Rails: If possible, use fintech providers that have local bank accounts in your destination country to avoid SWIFT intermediary fees.
3. Verify Details: Ensure the SWIFT/BIC and IBAN are 100% correct; errors in international transfers can lead to weeks of “tracing” fees.
4. Account for Fees: If you need to pay exactly $1,000 to a vendor, send $1,030-1,050 to cover potential intermediary bank deductions.

Final Thought: While the definition of “remit” is simple, the process is a relic of 20th-century banking. By understanding the roles of SWIFT and correspondent banks, you can navigate the system with fewer delays and lower costs.
