What Is a Wire Transfer? Meaning, Timing, and How It Differs from SEPA

A wire transfer is a method of transferring money electronically. It involves financial institutions exchanging instructions over a network, debiting the sender and crediting the recipient. Most wire transfer instructions are sent via the SWIFT network, but euro transfers between some European countries are processed on the SEPA network.

What is a wire transfer?

A wire transfer is an instruction from a sender’s financial institution to the recipient’s financial institution, requesting the recipient’s account to be credited. Instructions can pass through multiple institutions before reaching the recipient’s final institution. 

Most bank wire transfers occur on the SWIFT network, which processes the majority of cross-border transactions. There’s also the Single Euro Payments Area (SEPA) network, which processes foreign euro payments between 41 European countries, plus additional territories.

What the SWIFT network does

SWIFT, officially the Society for Worldwide Interbank Financial Telecommunications, is the secure messaging system that financial institutions use to exchange wire transfer instructions. All institutions plugged into the network have a unique SWIFT code, letting them quickly identify and communicate with each other. 

The SWIFT network doesn’t actually hold or transfer funds. Instead, it transmits payment instructions between financial institutions. 

How a wire transfer works

The payment path

An international wire transfer starts with the sender providing the beneficiary’s details (and the amount) to their financial institution. The sender’s institution verifies the instructions and, once verified, begins transmitting them to the beneficiary’s institution. Instructions may pass through one or two correspondent institutions before getting to the beneficiary’s institution. 

Details the sender is asked for

To process an international wire transfer, the sender’s institution asks for details, including 

• The beneficiary’s institution name
• The beneficiary’s account number or IBAN
• SWIFT code of the beneficiary’s institution
• A payment reference number and, in some cases, an address or identification for the sender or recipient.

Accuracy is essential when processing wire transfers, as wrong details are a major reason for delayed or rejected payments.

How long a wire transfer takes

A wire transfer takes anywhere from one to five days, depending on the instructions. The currency, amount, time zone between the sender and receiver, cutoff times, and compliance checks affect how long a wire transfer takes. For example, large transfers and first-time transfers usually take longer because of additional checks. 

Why a wire transfer can take longer

Large transfers generally require more compliance checks, making them take longer to process. Also, if the sender misses their institution’s daily cutoff time, transfer processing will be pushed to the next day, and the funds take longer to arrive. Transfers initiated on weekends or public holidays see similar delays.

Wire transfer vs. SEPA

What SEPA is

SEPA is a network that facilitates cross-border euro payments between 41 participating European countries and additional territories. It’s not just a messaging system like SWIFT but an integrated payment framework that standardizes and processes euro transfers. A SEPA payment doesn’t work like a typical international wire transfer, but instead is processed on an account-to-account transfer system between institutions. 

Wire transfer, SEPA Credit Transfer, and SEPA Instant

Here’s how a wire transfer, SEPA Credit Transfer, and SEPA Instant transfer differ in use cases, currency, timing, and other factors:

When each rail is the relevant one

• SEPA: A euro payment from one SEPA-participating country to another.
• SEPA Instant: A euro payment from one SEPA-participating country to another, if both the sender’s and recipient’s institutions support SEPA Instant.
• Wire transfer: A non-euro cross-border transfer between any countries, whether U.S. dollars, British pounds, Swiss francs, etc.

Before sending a wire transfer

What to check and what a beneficiary provides

What the sender checks:

• Recipient’s name
• Recipient’s institution and SWIFT code
• Account number or IBAN of the recipient

What the recipient provides:

They provide their name, institution and SWIFT code, and account number or IBAN to the sender. This information must be accurate to successfully process a wire transfer online.

Common questions

What is a domestic wire transfer?

The term “domestic wire transfer” is most commonly used in the U.S. market, denoting a transfer between domestic banks. However, in European markets where SEPA is available, domestic transfers are usually called “SEPA transfers” or “local transfers,” not wire transfers.

What’s the difference between a wire transfer and a bank transfer?

A wire transfer denotes electronic transfers, usually processed via the SWIFT messaging system, while a bank transfer is a broad term that covers both foreign and domestic transfers. 

Can you cancel a wire transfer?

A wire transfer generally can’t be cancelled once the sending institution has passed on the instructions. Always verify the details before sending because there’s no guarantee of cancelling a wire transfer.

A European payment account for euro transfers

Wire transfers are cross-border transactions associated with the SWIFT network, while SEPA transfers are exclusively euro transfers facilitated on the SEPA network. You can open a European business account on Satchel for remotely sending and receiving SEPA payments. Identity checks apply before creating one. If activated, a Satchel account enables seamless SEPA transactions for your business.
