International Wire Transfers: SWIFT, SEPA, CHAPS and How to Send Money Abroad

Sending money internationally seems straightforward — you tell your bank where to send it and how much — but the mechanics underlying international transfers are more complex than domestic payments. Understanding those mechanics explains why transfers sometimes take longer than expected, why fees are unpredictable, and how to choose the most efficient route for your situation.

SWIFT

SWIFT (Society for Worldwide Interbank Financial Telecommunication) is the messaging network that the overwhelming majority of international bank-to-bank transfers use. SWIFT does not itself move money — it transmits messages between banks instructing them to credit or debit accounts. The actual settlement of funds happens through a network of correspondent banking relationships.

How a SWIFT transfer works. When you instruct your bank to send money abroad, your bank identifies a route to the destination bank. If the two banks have a direct relationship — they hold accounts at each other — the transfer is relatively simple. Often they do not, and the payment routes through one or more correspondent banks — banks that act as intermediaries and have relationships with both ends of the chain. Each correspondent bank processes the payment instruction and may charge a fee.

SWIFT GPI. The SWIFT Global Payments Innovation (GPI) initiative has significantly improved international payment speed and tracking. Banks participating in GPI commit to processing payments quickly (most within 24 hours) and providing end-to-end tracking. SWIFT GPI is now standard at most major banks, though full adoption across smaller correspondent banks remains incomplete. When making a large transfer, it is worth asking your bank whether they support SWIFT GPI and providing a unique end-to-end transaction reference.

Costs. SWIFT transfer fees are typically charged in two ways: the sending bank charges a transaction fee (£15–£40 is common) and the recipient bank may charge a receiving fee. In addition, correspondent banks in the chain may deduct an intermediary charge (typically USD 5–25 each) from the transfer amount — which means the amount received can be less than the amount sent, even after the sending bank's fee is paid.

Timescales. Most SWIFT transfers complete within 1–3 business days. Complex routes through multiple correspondents, or payments subject to compliance screening, can take 3–5 business days.

SEPA

SEPA (Single Euro Payments Area) is a European payment network that standardises euro-denominated bank transfers across more than 40 countries and territories — the eurozone plus a number of additional European countries including the UK (for SEPA Credit Transfers only, post-Brexit, with some limitations). SEPA processes bank transfers within the zone efficiently, at low cost, and typically within one business day.

SEPA operates through two main schemes:

SEPA Credit Transfer (SCT). Standard euro transfers within the SEPA zone. Settlement within one business day. Fees are low — typically a few euros at most, and many banks offer free SEPA transfers. Requires IBAN and BIC of the recipient.

SEPA Instant Credit Transfer (SCT Inst). Near-real-time euro transfers (typically within 10 seconds) between participating banks. The previous €100,000 per-transaction cap was removed on 5 October 2025 under the EU Instant Payments Regulation, although individual banks may still set their own transaction limits. Under that regulation, euro-area banks must also offer instant transfers at no higher price than standard SEPA Credit Transfers. Adoption continues to grow.

For anyone regularly transferring euros within Europe — paying rent, receiving salary in euros, transferring between personal accounts — SEPA is the standard and cost-effective tool.

CHAPS

CHAPS (Clearing House Automated Payment System) is the UK's same-day high-value payment system. CHAPS is used for large domestic UK sterling transfers — property completions, large investment transfers, pension transfers — where same-day settlement is required. It is not an international payment system but is commonly used in conjunction with international transfers: for example, receiving SWIFT funds in a UK account and then making a CHAPS payment to a UK solicitor on the same day for a property completion.

CHAPS transfers typically cost £25–£35 at most high-street banks. CHAPS payments must be submitted before a cut-off time (typically around 2:00 pm–4:00 pm, varying by bank) to guarantee same-day settlement.

Tracking a transfer

Transfers can go wrong or be delayed. The most common causes are:

• Incorrect or incomplete beneficiary details (wrong IBAN, missing BIC, incorrect account name)
• Compliance screening — large or unusual payments may be held by the sending or correspondent bank for anti-money laundering checks
• Public holidays in one of the countries on the routing chain
• Correspondent bank processing delays

If a transfer has not arrived within the expected timeframe, the process for tracing it is:

1. Contact your sending bank and ask for the SWIFT transaction reference (also called UETR if the payment is SWIFT GPI)
2. Ask your bank to trace the payment — they can send a SWIFT gSRP (payment status request) message to identify where the payment is in the chain
3. If the payment has been credited to a correspondent but not forwarded, the correspondent can be contacted directly via the bank

Alternatives for smaller amounts

For transfers under approximately £10,000–£20,000, specialist platforms offer faster, cheaper alternatives to traditional SWIFT:

Wise (formerly TransferWise). Uses a peer-to-peer model to match transfers in opposite directions, avoiding the correspondent banking chain entirely for supported currency pairs. Charges a small percentage fee (typically 0.3–1%) plus a fixed fee, at the mid-market rate. Regulated by FCA. Fastest option for many currency pairs.

Revolut. Offers international transfers at competitive rates, particularly for currencies within its supported range. Useful for day-to-day transfers of smaller amounts.

Both Wise and Revolut have per-transfer limits that may not be suitable for very large amounts. For property purchases or large investment transfers, a specialist FX broker combined with a SWIFT transfer is typically more appropriate.
