A SWIFT transaction is an international payment instruction sent between banks through the SWIFT messaging network. Despite how it sounds, SWIFT doesn’t actually move money. It sends secure, standardized messages that tell banks where to send funds, how much to send, and who should receive them. The actual money moves separately through the banks’ own accounts with each other.
How SWIFT Transactions Work
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It operates as a messaging network that more than 11,000 financial institutions in over 200 countries use to communicate payment instructions. Think of it like a highly secure postal service for banks: it delivers the letter, but it doesn’t carry the cash.
Here’s what happens in a typical SWIFT transaction. Say you need to send money from your U.S. bank account to a friend’s account at a bank in Italy. Your bank creates a SWIFT message containing the payment details and sends it over the network to the Italian bank. When the Italian bank receives that message, it credits the funds to your friend’s account. The two banks settle the actual money between themselves through accounts they hold with each other, or through one or more intermediary banks if they don’t have a direct relationship.
Those intermediary banks (sometimes called correspondent banks) are a key part of the system. If your bank and the recipient’s bank don’t hold accounts with each other directly, the payment gets routed through one or more banks that bridge the gap. Each intermediary bank in the chain processes the message and passes it along. This is why some international transfers take longer and cost more than others: each extra bank in the chain adds time and potentially fees.
Information You Need to Send One
To initiate a SWIFT transaction, you’ll need to provide your bank with a few specific pieces of information. According to U.S. Bank, the essentials are:
- Receiving bank’s SWIFT code: An 8- or 11-character code that identifies the specific bank and branch. Every institution on the SWIFT network has one. For example, U.S. Bank’s SWIFT code is USBKUS44IMT.
- Receiving bank’s name and address: The full legal name and location of the bank receiving the funds.
- Recipient’s name and account number: The person or business receiving the money, along with their account number. In many countries, especially in Europe, you’ll also need an IBAN (International Bank Account Number), which is a standardized format that includes the country code, bank identifier, and account number in one string.
- Recipient’s address: The physical address of the person or business receiving the payment.
Getting any of these details wrong can delay your transfer or cause it to be returned. Double-check the SWIFT code and account number before submitting.
How Long a SWIFT Transaction Takes
SWIFT transactions are faster than most people expect. Thanks to SWIFT’s Global Payments Innovation (gpi) initiative, nearly 60% of cross-border payments are credited to the recipient’s account within 30 minutes. Almost 100% arrive within 24 hours.
The biggest factor affecting speed is how many intermediary banks sit between the sender and recipient. A transfer between two banks that hold accounts directly with each other can clear in minutes. A payment that needs to pass through two or three correspondent banks might take a full business day or occasionally longer, especially if the payment crosses time zones and lands outside of a bank’s operating hours.
Currency also plays a role. Transfers in major currencies like U.S. dollars, euros, or British pounds tend to process faster because there are more direct banking relationships and higher transaction volumes. Payments involving less commonly traded currencies may require additional intermediary steps.
Tracking Your Payment
One of the biggest improvements to the SWIFT system in recent years is end-to-end tracking. SWIFT gpi introduced a Unique End-to-End Transaction Reference (UETR) for every payment, which works like a tracking number for a package. You can see exactly where your money is at every stage of the process.
Since November 2020, financial institutions on the SWIFT network are required to confirm when a payment has been credited, is on hold, or has been transferred outside of SWIFT. This means your bank can tell you in real time whether your payment has arrived, is still in transit, or is stuck somewhere in the chain. SWIFT gpi also includes a stop-and-recall service that lets banks halt a payment that’s still in flight if something goes wrong, notifying every institution in the chain automatically.
Who Pays the Fees
SWIFT transactions typically involve fees from multiple banks: your own bank’s outgoing wire fee, any intermediary bank charges, and sometimes a fee from the receiving bank. Total costs vary widely, but international wire fees at major banks commonly range from $15 to $50 on the sending side alone, with intermediary charges adding more on top.
When you initiate a SWIFT transfer, you’ll usually choose one of three fee codes that determine who absorbs those costs:
- OUR: You, the sender, pay all fees, including intermediary bank charges. The recipient gets the full amount you sent.
- BEN: The recipient (beneficiary) pays all fees. The charges are deducted from the transfer amount, so the recipient receives less than what you originally sent.
- SHA (shared): You pay your bank’s outgoing fee, and any intermediary or receiving bank charges are deducted from the amount in transit. Both sides share the cost.
SHA is the most common option for personal transfers. If you’re paying an invoice or sending money where the recipient needs to receive an exact amount, OUR ensures nothing gets deducted along the way. Keep in mind that choosing OUR is usually the most expensive option for the sender, since you’re covering charges from banks you don’t even have a relationship with.
When SWIFT Transactions Are Used
SWIFT transactions are the standard method for sending money across borders between bank accounts. You’ll encounter them when wiring money to family overseas, paying for international real estate, settling invoices with foreign suppliers, or receiving a salary from an employer in another country. Businesses use them heavily for trade payments, and they remain the backbone of global interbank communication.
For smaller personal transfers, online money transfer services may offer lower fees or better exchange rates than a traditional SWIFT wire. But for large sums, business payments, or transfers where you need the security and traceability of bank-to-bank communication, SWIFT remains the dominant system. The network processes tens of millions of messages per day, and its standardized format is what makes it possible for banks in different countries, using different systems and languages, to understand each other’s payment instructions instantly.
