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.

The exchange rate usually costs more than the fee

Most people compare transfer providers on the visible charge, which is the smaller of the two costs on any sizeable payment. The larger cost is the margin applied to the exchange rate — the difference between the rate at which currency actually trades between banks and the rate you are offered.

That margin is not usually disclosed as a fee. It is embedded in the rate, which is why two providers quoting the same headline charge can deliver materially different amounts to the beneficiary. The practical discipline is simple: before you send, look up the interbank rate for the pair, then look at the rate you are being offered, and treat the gap as part of the price. On a small payment the difference is trivial and the fixed fee dominates. On a property deposit or a pension transfer, the relationship reverses entirely and the rate is almost the only thing that matters.

Two corollaries follow. First, ask whether a better rate is available on larger amounts — for many providers it is, but the improved rate is offered rather than published, so it goes to the customers who ask. Second, splitting a large transfer into several smaller ones to stay within a platform's limits usually costs more, not less, because you pay the margin repeatedly and may lose the volume treatment altogether.

Choosing the fee option deliberately

The SHA, OUR and BEN instruction is presented as an administrative box and is in fact a decision with consequences. The default, shared charges, means intermediary and receiving charges come out of the transfer, so the amount arriving is not the amount sent. That is usually harmless for a routine payment and actively damaging where a precise sum is required.

Payments where a shortfall causes a real problem include property completions, tax payments, school fee invoices, minimum subscription amounts for an investment, and any payment where the recipient must reconcile an exact figure. For these, instructing that the sender bears all charges is worth the extra cost, because the alternative is a shortfall discovered by the recipient at the worst possible moment and a second payment to make it good.

Large and time-critical transfers

For anything substantial or dated, the failure modes are predictable enough to plan around.

• Send a small test payment first. Where a relationship is new and the timetable allows, a nominal amount confirms that the details work end to end. The cost is one fee; the alternative is a large sum sitting unresolved in a correspondent chain.
• Work backwards from the deadline. Cut-off times, weekends and public holidays in every country on the routing chain all apply, and a payment initiated late in the day may not be processed until the next working day at the sending bank, let alone at the receiving one.
• Warn the bank in advance. A payment far outside your normal pattern is precisely what monitoring systems are designed to flag. Telling the bank what is coming, and why, before you initiate it converts a hold into a formality.
• Have the supporting documents ready. A sale contract, a completion statement, a fund subscription agreement or a scheme transfer instruction will answer most compliance questions immediately.
• Keep the reference field meaningful. Recipients that handle many incoming payments — solicitors, developers, schools, fund administrators — match on the reference. An unlabelled receipt can sit unallocated for days.

Payment redirection fraud

The largest single risk in an international transfer is not the banking system failing. It is the banking system working perfectly on a payment you were tricked into authorising.

The pattern is consistent. A criminal gains access to correspondence between two parties in a transaction, usually by compromising an email account, and sends the payer amended bank details shortly before payment is due. The details look plausible, the timing is right, the tone matches previous messages, and the payer sends the money to an account controlled by the fraudster. Because the payer authorised the payment, recovery is difficult and often impossible once the funds have moved on.

The defence is procedural rather than technical. Verify beneficiary details by telephone, on a number you already held and did not take from the email requesting payment, and treat any late change of bank details as suspicious by default however reasonable the explanation sounds. Where a transaction involves a solicitor, agent or developer, agree at the outset how details will be confirmed. It is a short conversation that prevents the most expensive mistake in this guide.

What to have ready before you initiate

• The beneficiary's full legal name exactly as the receiving bank holds it
• IBAN or account number, and BIC or SWIFT code
• The beneficiary bank's name and address, and in some corridors the branch or routing detail
• The beneficiary's address, which some corridors require
• The purpose of the payment, and documentation supporting it for larger sums
• Your chosen charge instruction, and confirmation of the rate applied

Currency values move, and the amount a recipient receives in their own currency will differ from the amount you expect if the rate changes between quotation and execution. Where an exact sum in the destination currency is essential, agree how the rate is fixed before you send.
