SWIFT Transfers Explained: How They Work, Fees, and Timing

A SWIFT transfer is an international bank-to-bank payment sent via the SWIFT network — the global messaging system used by more than 11,000 financial institutions in over 200 countries. SWIFT doesn’t move money itself. It sends secure instructions between banks telling them where to send funds, how much, and in which currency. Transfers typically take 1 to 4 business days and cost a mix of fixed fees plus an exchange rate margin.

This guide covers how SWIFT works, exactly what it costs, how long it takes, what information you need, and how it compares to alternatives like SEPA and specialist currency brokers. For the full fee picture, see our guide on bank wire transfer fees explained. For delivery times, see how long international bank transfers take.

What Is a SWIFT Transfer?

SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It’s a Belgian-based cooperative that runs the secure messaging network banks use to send payment instructions across borders. When you make a SWIFT transfer, a standardised message called an MT103 is sent from your bank to the recipient’s bank. The terms SWIFT transfer, telegraphic transfer (TT), and international wire transfer are used interchangeably.

How Long Does a SWIFT Transfer Take?

Most SWIFT transfers take 1 to 4 business days. The exact time depends on: direct vs indirect routing (intermediary banks add delay), time zones, compliance checks on larger amounts, cut-off times (each bank has a daily SWIFT cut-off, usually early afternoon local time), and weekends/public holidays. SWIFT gpi (Global Payments Innovation) is the modern upgrade — around half of all payments credit within 30 minutes and almost all complete within 24 hours, with end-to-end UETR tracking. See the full breakdown of how long international transfers take by destination.

What Does a SWIFT Transfer Cost?

A SWIFT transfer has two separate costs. Most people only see the first one.

1. Fixed transfer fees: Sending bank fee (£10–£40 for most UK banks), intermediary bank fees (£10–£30 per intermediary, deducted mid-flight), and receiving bank fee (often £5–£20). You can select who pays via SWIFT charge codes: OUR (sender pays all), BEN (recipient pays all), or SHA (each side pays their own).

2. Exchange rate margin (the hidden cost): Most banks quote a rate 2–5% worse than the live interbank rate. On a £50,000 transfer, a 3% margin costs £1,500. Specialist currency brokers charge margins of 0.25–1.5% and no transfer fee. See our full cost to transfer money abroad guide for a bank-by-bank breakdown, and why banks give worse exchange rates.

What Information Do You Need for a SWIFT Transfer?

To send a SWIFT transfer, you need: full legal name of the account holder, recipient’s address, IBAN (required for most European and many other destinations), account number (used where IBANs aren’t standard — e.g. the US, Canada, Australia), SWIFT/BIC code (8 or 11 characters identifying the recipient’s bank), bank name and address, and routing number or sort code (sometimes required). For a guide to the difference between routing numbers and sort codes, see our sort code vs routing number guide.

How a SWIFT Transfer Works: Step by Step

1. You instruct the transfer — provide recipient details, amount, and currency to your bank or broker
2. Compliance and identity checks run (AML, sanctions, fraud screening)
3. Exchange rate is locked if a currency conversion is needed
4. Funds are debited from your account
5. MT103 message is sent via SWIFT to the recipient’s bank, directly or via correspondent banks
6. Intermediary settlement happens if needed
7. Recipient bank credits the account after their own compliance checks

When Should You Use a Currency Broker Instead of a Bank?

Use a specialist currency broker when you’re transferring £5,000 or more, want to lock a rate in advance with a forward contract, need recurring international payments for pensions or payroll, or want a named dealer who verifies beneficiary details before funds go out. See our guide on transferring large sums internationally and who gives the best exchange rates for large transfers.

Common SWIFT Transfer Scenarios

SWIFT is the mechanism behind most large UK international payments: paying USD invoices from the UK, paying euro bills from the UK, property purchases in Spain, and receiving UK pension income abroad. The same network, the same fees — but very different outcomes depending on whether you use a bank or a specialist. All Cambridge Currencies transfers are processed through FCA-authorised payment partners and are fully safeguarded.

Frequently Asked Questions

What is a SWIFT transfer in simple terms?

How long does a SWIFT transfer take?

Most SWIFT transfers take 1 to 4 business days. SWIFT gpi payments often arrive within 30 minutes to 24 hours.

How much does a SWIFT transfer cost?

Banks typically charge £10–£40 in fees plus a 2–5% exchange rate margin. Specialist brokers charge no fee and margins of 0.25–1.5%.

Why is the exchange rate more important than the fee?

A £20 fee is fixed, but a 3% exchange rate margin on £50,000 is £1,500. On any transfer above a few thousand pounds, the rate decides the true cost — not the headline fee.
