Have you ever thought about how money travels around Europe so easily nowadays? Well, it all comes down to SEPA. So, if you’ve sent euros to a friend in Paris or paid a bill in Berlin, you’ve likely used SEPA – or Single Euro Payments Area.

This is a financial system that was introduced just to make moving money between European countries easier, more convenient, and with fewer costs.

But how does the process work? We are interested in the details of this system, which is why we decided to take a deep dive into how SEPA payments are processed.

Even though it might appear as a simple system, if we break it down, we can see the use of complex technologies that make all of this possible. The SEPA system is the lifeline of the European continent, which allows money to circulate between countries as fast as possible.

So, how does it work? Let’s find out.

Initiate the Transfer

So, it all starts with you, or whoever is sending the money. Let’s say that you are in Dublin, wanting to see the next Real Madrid match in the Champions League with your friend from Madrid.

How will you send the money for the tickets? Well, you need to log into their banking app or go to a physical branch if you are old-school and set up a SEPA transfer.

You then need to enter a bunch of financial information like International Bank Account Number (IBAN), and sometimes banks require you to enter Bank Identifier Code (BIC), but in most cases, IBAN is enough for SEPA transfers.

Then, you just type the amount, let’s say €350, add a note “Money for Tickets” and hit send. Some banks don’t have SEPA transfers in their apps, so you might be required to go to a physical location.

The Banks Job

Now that you’ve given the green light and sent the transaction, your bank takes over. They check your account first (have you got enough euros to cover it + fees?). If yes, they debit your €350 (plus any tiny fee they might charge, although SEPA rules keep those low).

The next step is to bundle your payment details into a digital message, just like a secure email, with all the payment information like your IBAN, your friend’s IBAN, the amount, and notes.

This message follows a standard called ISO 20022, which is like a universal language all SEPA banks must speak.

The Middleman

Now, your money doesn’t travel immediately to Madrid. Instead, it hands the payment off to a clearing house, which is sort of like the middleman that keeps SEPA transactions going. In Europe, there are systems like EBA Clearing’s STEP2 or the European Central Bank’s TARGET2 that act as the middleman.

They process millions of transactions daily (over 46 billion a year – over 46 billion a year, according to the European Payments Council’s 2024.

But what is the job of the clearing house? Well, they are responsible for verifying all the information. Whether the IBAN is legit, is it formally, right? If it’s a standard SEPA Credit Transfer (SCT), they also aim to settle it within one business day.

But if you picked SEPA Instant Credit Transfer (SCT Inst), which has been available since 2017, your transaction will settle in 10 seconds after your bank initiates the payment to the network, and the system works 24/7, making money transfer between European countries faster and easier than ever before.

Receiving the Transaction

The next step is your friend in Madrid receiving the transactions. They get all the payment details from the clearing house, and credit his account with the €350 you sent. In some cases, banks will usually require him to state the source of income and process the transaction within 1 business day or may ask for additional documents.

So, for regular SCT, your friend, we’ll see the money by the next business day, and with SCT instant, the money is there in just a few minutes.

Everyone’s Happy (Usually)

That’s it—money moved; mission accomplished. SEPA’s whole deal is making this smooth and cheap. Back in 2008, when it launched, cross-border payments were a hassle, slow, and pricey.

Now, the European Commission says fees can’t exceed what you’d pay domestically, often nothing at all. In 2024, Regulation (EU) 2024/886 even mandated instant payments as an option across all 36 SEPA countries (27 EU states plus Iceland, Norway, etc.), so banks have to offer that 10-second magic alongside the one-day version.

What’s Under the Hood?

Behind the scenes, it’s not just banks chatting—it’s a system built on trust and tech. The European Payments Council sets the rules, ensuring every bank from Lisbon to Helsinki plays nice.

Your payment’s encrypted, tracked via IBANs, and backed by laws like the Payment Services Directive (PSD2), which adds fraud protection. If something goes wrong—like a typo in the IBAN—you might need to chase your bank, but SEPA’s refund rules (up to 13 months for direct debits) have your back.
