Breaking Down The Three Most Common Bank Transfer Networks

Sending money across borders shouldn’t feel like solving a puzzle.

For the average consumer however, bank transfers are synonymous with complex acronyms, lengthy processing times and hidden fees. There are three primary networks that process the majority of bank-to-bank payments worldwide:

• SWIFT
• SEPA
• ACH

Every provider works differently. Fees vary. And they each offer different transfer options, such as direct-to-card transfers, which are quickly becoming a popular alternative internationally.

Learn everything there is to know about all three networks and when to apply them…

Here’s what’s covered:

1. What Are Bank Transfer Networks?
2. How SWIFT Transfers Work
3. How SEPA Transfers Work
4. How ACH Transfers Work
5. Where Direct-to-Card Transfers Fit In

What Are Bank Transfer Networks?

A bank transfer network is the system that moves money between banks.

Each network is like its own money postal service. They each have different rates, speed, fees and geographic locations they serve. When you transfer money from your bank account to another person’s, it gets sent through one of these networks behind the scenes.

The three biggest are:

1. SWIFT — global bank-to-bank wires
2. SEPA — euro transfers across Europe
3. ACH — domestic transfers within the US

For anyone considering newer alternatives such as direct-to-card transfers, this SWIFT vs SEPA vs ACH transfers explained blog is a great place to start. It features a comparison of each network and discusses speed, fees and ideal use cases.

However, to fully comprehend the differences between each network you must understand how each network actually functions. Let’s digress…

How SWIFT Transfers Work

SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication.

SWIFT is the largest global banking network. It facilitates cross-border payments for over 11,500 institutions globally across 200+ countries.

Here’s the thing most people don’t realise…

SWIFT isn’t moving any money around. It’s simply a messaging service. When a SWIFT transfer is initiated the network transfers encrypted payment messages from bank to bank. The money itself moves via correspondent banks in the background.

That’s why SWIFT transfers can be:

• Slow — typically 1 to 5 business days to settle
• Expensive — fees usually range from $20 to $50 per transfer
• Unpredictable — intermediary banks often deduct extra charges along the way

The painfully slow and expensive process is one of the reasons why direct-to-card transfers gained popularity for cross-border payments.

Best for: Large international wires where speed is not essential and the sender prefers the security of dealing with an established network.

How SEPA Transfers Work

SEPA (Single Euro Payments Area) handles euro-denominated transfers across Europe.

SEPA spans 41 countries – all EU countries, and some non-EU countries such as Norway, Switzerland and Iceland. SEPA was designed to make euro transfers across borders as easy as making national transfers within each country.

There are two main types of SEPA transfers:

SEPA Credit Transfer: The standard option. Funds usually arrive within one business day.

SEPA Instant: The newer, faster option. Funds arrive in under 10 seconds, 24/7.

And here’s a big change for 2025-2026…

Effective October 2025, EU regulation mandated that all banks within the eurozone provide SEPA Instant transfers and they must be free of additional charges when compared to normal transfers. SEPA is one of the easiest transfer networks to use globally.

Best for: Sending euros to another bank account within the SEPA zone. It’s quick, inexpensive, and convenient.

How ACH Transfers Work

ACH (Automated Clearing House) is the backbone of US domestic payments.

It processes payroll, bill pay, person to person payments, and business payments. ACH is also the network that most bank accounts in the US use behind the scenes.

It’s big data. Throughout 2024, the ACH network processed 33.6 billion payments valued at $86.2 trillion. That’s 141 million transactions per day.

ACH transfers come in two main flavours:

• Standard ACH: Takes 1 to 3 business days. Fees are extremely low and often free for consumers.
• Same-Day ACH: Settles within hours, with a limit of $1 million per transaction.

The catch? ACH only transfers money domestically. For international transactions, senders must use SWIFT (or newer alternatives like direct-to-card).

Best for: Domestic US transfers, payroll, recurring payments, and bill pay.

Where Direct-to-Card Transfers Fit In

Here’s where things get interesting…

Regular bank transfers (SWIFT, SEPA, ACH) always need the recipient to have a bank account. What if the recipient has only a debit card? There are direct-to-card transfers for that.

Direct-to-card transfers distribute funds directly to the recipient’s debit card through card networks such as Visa Direct or Mastercard Send. They are a relatively new method of transferring funds and they solve many issues found in traditional networks.

Why direct-to-card transfers are gaining popularity:

• Speed: Funds usually arrive in minutes, not days
• Global reach: Works in countries where SWIFT is slow or expensive
• No bank account needed: Recipients only need a debit card
• Transparent fees: No surprise intermediary charges

Sending money internationally to friends and family members in nations that lack widespread banking services can be much more efficient with direct-to-card transfers than with a standard SWIFT wire.

 

Here’s some context for that gap: the global average cost of sending $200 was 6.5% in early 2025. That’s over twice the global target of 3%.

Which Network Should You Use?

It really depends on what’s being sent and where it’s going.

Here’s a quick guide:

• Sending money internationally between bank accounts? SWIFT works, but expect fees and delays.
• Sending euros within Europe? SEPA is fast, cheap, and easy.
• Sending money inside the US? ACH is the cheapest option for domestic transfers.
• Sending money to someone without an account? Sending money directly to a card is typically the best option.

The right decision can save you hours and dollars. The wrong decision can cost you more in fees than the transfer is worth.

Bringing It All Together

Bank transfers aren’t as simple as they look.

SWIFT, SEPA and ACH are each money movers. SWIFT wires are the global standard. SEPA rules euro transactions in Europe. ACH processes most domestic payments in the US.

But none of these networks are perfect.

Slow speeds, opaque fees and limited accessibility are problems — particularly for international payments. That’s where direct-to-card transfers come in. These payments are growing in popularity because they provide speed, transparency, and worldwide accessibility that legacy networks can’t match.

Before you send money overseas next time, pause and consider which network will work best for you. The best choice can save you days and dollars.
