But what exactly is SWIFT? How does it work? How long does it take? And what should you know before sending your next international payment?

This guide covers everything you need to know about SWIFT international wires.

What Is SWIFT?

SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It is not a bank and does not hold or move money itself.

Instead, SWIFT provides a highly secure messaging network that allows financial institutions around the world to communicate standardized payment instructions to one another.

Today, SWIFT connects more than 11,000 financial institutions across over 200 countries and territories, making it the most widely used network for international bank transfers.

Think of SWIFT as the global postal service for banks: it delivers the message that tells banks where money should go and how much should be transferred.

How Does a SWIFT Wire Transfer Work?

When you send an international wire through the SWIFT network, several steps occur behind the scenes:

1. The Sender Initiates the Transfer

The sender provides:

• Recipient's full name
• Recipient's bank name
• Account number or IBAN
• SWIFT/BIC code
• Transfer amount and currency

2. SWIFT Sends the Payment Instructions

The sending bank transmits a secure SWIFT message to the recipient's bank (or intermediary banks if needed).

3. Correspondent Banks May Get Involved

Not all banks maintain direct relationships with one another.

In many cases, one or more intermediary (correspondent) banks help route the transaction to its final destination.

4. Funds Arrive at the Recipient Bank

Once the receiving bank gets payment confirmation and settlement instructions, the funds are credited to the beneficiary's account.

What Is a SWIFT Code?

A SWIFT Code (also called a BIC – Bank Identifier Code) identifies a specific financial institution during international transfers.

A SWIFT code typically contains:

Section	Purpose
First 4 characters	Bank code
Next 2 characters	Country code
Next 2 characters	Location code
Last 3 characters (optional)	Branch code

Example:

BOFAUS3NXXX

• BOFA = Bank of America
• US = United States
• 3N = New York
• XXX = Main branch

Without the correct SWIFT code, an international payment may be delayed, rejected, or returned to the sender.

SWIFT vs. IBAN: What's the Difference?

Many people confuse SWIFT codes and IBANs.

They serve different purposes:

SWIFT/BIC	IBAN
Identifies the bank	Identifies the specific account
Used worldwide	Common in Europe, Middle East, and parts of Africa
Required for most international wires	Required in countries that use the IBAN system

A useful way to think about it:

• SWIFT tells money where the bank is.
• IBAN tells money which account inside the bank to reach.

How Long Does a SWIFT Transfer Take?

Most SWIFT payments arrive within:

✅ 1–3 business days

However, several factors can affect delivery speed:

Faster Transfers

• Direct banking relationships
• Major currencies (USD, EUR, GBP)
• Complete recipient information
• Banks participating in SWIFT gpi tracking

Slower Transfers

• Multiple intermediary banks
• Compliance reviews
• Public holidays
• Time zone differences
• Missing or incorrect information

In some cases, transfers can take 4–5 business days or longer, particularly when additional verification is required.

What Information Is Required to Send a SWIFT Wire?

Before sending an international transfer, make sure you have:

Recipient Information

• Full legal name
• Address (sometimes required)

Banking Details

• Bank name
• Bank address
• Account number or IBAN
• SWIFT/BIC code

Payment Information

• Currency
• Transfer amount
• Reason for payment (when required for compliance)

Even a small typo can result in delays, investigations, or returned funds, so accuracy is critical.

What Are the Fees for SWIFT Transfers?

International wire fees can come from several sources.

Sending Bank Fee

Most banks charge a fixed outgoing wire fee.

Intermediary Bank Fees

If correspondent banks handle the payment, they may deduct additional charges during processing.

Receiving Bank Fee

Some recipient banks charge a fee to receive international transfers.

Exchange Rate Margin

This is often the largest hidden cost.

Many financial institutions add a markup to the exchange rate, increasing the total cost of the transaction without displaying it as a separate fee.

---

What Are SWIFT Fee Types?

SWIFT transfers generally use one of three fee structures:

OUR

The sender pays all fees.

The recipient receives the full transfer amount.

SHA

Fees are shared.

Each party pays charges from their own bank.

BEN

The recipient pays all fees.

Charges are deducted from the transferred amount.

For business payments and supplier invoices, OUR is often preferred to ensure the beneficiary receives the exact amount expected.

What Is SWIFT gpi?

SWIFT Global Payments Innovation (gpi) is a modernization initiative that improves speed, transparency, and tracking.

Benefits include:

• Faster settlement times
• End-to-end payment tracking
• Greater transparency of fees
• Real-time status updates

Many international payments now arrive within hours rather than days thanks to SWIFT gpi.

For businesses managing global cash flow, this added visibility can be extremely valuable.

Common Reasons SWIFT Transfers Get Delayed

Even well-prepared transactions can be delayed.

Some common reasons include:

Incorrect Bank Details

The most common cause of failed or delayed wires.

Compliance Reviews

Banks must screen transactions for:

• Anti-money laundering (AML) requirements
• Sanctions screening
• Regulatory requirements

Missing Documentation

Large-value or high-risk transfers may require additional information before processing.

Intermediary Bank Routing

Each additional bank in the chain can introduce processing delays.

---

Are SWIFT Wires Secure?

Yes.

SWIFT is considered one of the most secure international financial communication networks in the world.

Security measures include:

• Encrypted communications
• Authentication protocols
• Standardized message formats
• Continuous monitoring and compliance controls

While no system is immune to fraud attempts, SWIFT remains the global standard for secure cross-border banking communications.

Flexi Tip: Before sending an international wire, always compare the total cost—not just the transfer fee. Exchange rate markups and intermediary bank charges can significantly impact the final amount your recipient receives.
