What Is SWIFT?
Bank TransferSWIFT (Society for Worldwide Interbank Financial Telecommunication) is the global messaging network that banks use to securely send and receive international wire transfer instructions. It connects over 11,000 financial institutions in more than 200 countries, handling the majority of cross-border payments worldwide.
How It Works
1. **Initiation**: The sender instructs their bank to make an international wire transfer, providing the beneficiary's account details, SWIFT/BIC code, transfer amount, and currency. 2. **SWIFT message**: The sending bank creates a standardized SWIFT message (typically MT103 for customer payments) and transmits it through the secure SWIFT network. 3. **Routing**: If the sending and receiving banks don't have a direct relationship, the message is routed through one or more correspondent (intermediary) banks. 4. **Compliance checks**: Each bank in the chain performs anti-money laundering (AML), sanctions screening, and other compliance checks, which may add processing time. 5. **Settlement**: Banks settle funds through their correspondent banking relationships using nostro/vostro accounts. Each intermediary processes its leg of the transfer. 6. **Credit**: The beneficiary's bank receives the SWIFT message and credits the funds to the recipient's account, completing the transfer.

Pros & Cons
- True global reach — SWIFT connects over 11,000 financial institutions in 200+ countries, making it the only payment method that can reach virtually any bank account in the world.
- Supports all major currencies (150+), enabling businesses to send and receive payments in the currency of their choice across international borders.
- Highly secure — SWIFT uses multi-layered security including encryption, authentication, and integrity checking. The network has an excellent track record for message security.
- SWIFT gpi has dramatically improved speed and transparency, with nearly 50% of payments arriving within 30 minutes and full end-to-end tracking available.
- Suitable for high-value transfers — there are typically no per-transaction limits imposed by SWIFT itself, making it appropriate for large B2B payments, trade finance, and corporate treasury operations.
- Expensive — total fees for a single transfer can range from $25 to $100+, including sending bank fees, correspondent bank charges, and receiving bank fees.
- Slow compared to modern alternatives — standard transfers take 1-5 business days due to correspondent banking chains, compliance checks, and time zone differences.
- Fee unpredictability — when fees are shared (SHA) or paid by the beneficiary (BEN), the exact amount deducted by intermediary banks is often unknown in advance.
- Correspondent banking adds complexity — payments may pass through multiple intermediary banks, each adding fees and potential delays, with limited visibility into the chain.
- Not suitable for small or frequent payments — the high per-transaction cost makes SWIFT impractical for low-value transfers, subscriptions, or consumer payments.
Use Cases
- International B2B payments — businesses use SWIFT to pay overseas suppliers, vendors, and partners in their local currency.
- Cross-border payroll — companies with international employees use SWIFT wire transfers to pay salaries in countries without local payment infrastructure.
- Trade finance — importers and exporters use SWIFT for letters of credit, documentary collections, and payment for goods shipped internationally.
- Foreign direct investment — corporations use SWIFT for large-value capital transfers when investing in foreign subsidiaries or acquiring overseas assets.
- Remittances — individuals and money transfer operators use SWIFT to send funds to family members or beneficiaries in other countries.
SWIFT, the Society for Worldwide Interbank Financial Telecommunication, is the dominant global network for international bank-to-bank financial messaging. Founded in 1973 and headquartered in La Hulpe, Belgium, SWIFT connects more than 11,000 financial institutions across over 200 countries and territories. It is the infrastructure behind the vast majority of international wire transfers, processing an average of over 45 million messages per day. When a business or individual sends money internationally between banks, the payment instruction almost certainly travels over the SWIFT network.
## What Is SWIFT?
It is important to understand that SWIFT itself does not move money. SWIFT is a messaging network — it transmits standardized payment instructions between banks, telling them how much to transfer, from which account, to which account, in which currency. The actual movement of funds is handled by the banks themselves through their correspondent banking relationships and settlement systems.
Think of SWIFT as the postal service for banks. When you send an international wire transfer, your bank creates a SWIFT message containing all the payment details and sends it to the recipient's bank (or through intermediary banks). The receiving bank then acts on the instruction by crediting the beneficiary's account.
SWIFT is owned and governed cooperatively by its member financial institutions, overseen by the National Bank of Belgium in partnership with the central banks of the G10 countries.
## SWIFT Codes and BIC
Every bank on the SWIFT network is identified by a unique SWIFT code, also known as a BIC (Bank Identifier Code). A SWIFT/BIC code is 8 or 11 characters long and encodes the bank's identity and location:
- **Characters 1-4**: Bank code (identifies the institution) - **Characters 5-6**: Country code (ISO 3166-1 alpha-2) - **Characters 7-8**: Location code (city or region) - **Characters 9-11** (optional): Branch code (specific branch; "XXX" or omitted for the head office)
For example, "CHASUS33" is the SWIFT code for JPMorgan Chase's head office in New York. When initiating an international wire transfer, you need the recipient's SWIFT/BIC code along with their IBAN or account number to route the payment correctly.
## How SWIFT Messages Work
SWIFT messages follow standardized formats known as MT (Message Type) or the newer MX (ISO 20022) format. The most common message type for customer wire transfers is MT103, which contains all the information needed to process a payment: sender and receiver details, amount, currency, charges, and remittance information.
A typical SWIFT payment flow works as follows:
1. **Initiation**: The sender instructs their bank to make an international wire transfer, providing the beneficiary's name, account number/IBAN, SWIFT/BIC code, amount, and currency. 2. **Message creation**: The sending bank creates a SWIFT MT103 message and transmits it through the SWIFT network. 3. **Correspondent banking**: If the sending bank does not have a direct relationship with the receiving bank (which is common), the message is routed through one or more intermediary (correspondent) banks that facilitate the transfer between the two. 4. **Settlement**: Each bank in the chain settles its portion of the transfer. The sending bank debits the sender's account, correspondent banks move funds between their nostro/vostro accounts, and the receiving bank credits the beneficiary. 5. **Confirmation**: The beneficiary's bank notifies the recipient that funds have been received.
## Correspondent Banking
Correspondent banking is a critical part of how SWIFT transfers work. Most banks do not maintain direct relationships with every other bank in the world. Instead, they maintain accounts (nostro accounts) with larger correspondent banks that serve as intermediaries. A single SWIFT transfer might pass through two or three correspondent banks before reaching its destination.
Each correspondent bank in the chain may deduct a fee from the transfer and may add processing time. This is why international wire transfers can be expensive and slow — each intermediary takes its cut and adds its processing time.
## Fees
SWIFT transfers are among the more expensive payment methods. Typical fees include:
- **Sending bank fee**: $15-$50 for outgoing international wire transfers - **Correspondent bank fees**: $10-$30 per intermediary bank (there may be 1-3 intermediaries) - **Receiving bank fee**: $0-$20 for incoming international wires - **Currency conversion**: 1-4% markup on the exchange rate
In total, a single international wire transfer can cost anywhere from $25 to $100 or more, depending on the banks involved, the corridor (which countries), and the fee structure chosen:
- **OUR**: Sender pays all fees (most expensive for sender but full amount reaches beneficiary) - **SHA (Shared)**: Sender pays sending bank fees, beneficiary pays receiving bank fees - **BEN**: Beneficiary pays all fees (deducted from the transfer amount)
## Processing Time
SWIFT transfers typically take 1 to 5 business days, depending on the countries involved, the number of correspondent banks in the chain, time zones, local banking cut-off times, and any compliance checks that need to be performed. Transfers between major banking centers (US to UK, for example) often settle in 1-2 business days. Transfers to less connected banking systems in developing countries may take 3-5 business days.
## SWIFT gpi
SWIFT gpi (Global Payments Innovation), launched in 2017, is an initiative to improve the speed, transparency, and traceability of cross-border payments on the SWIFT network. SWIFT gpi introduces:
- **End-to-end tracking**: A unique tracking reference (UETR) allows senders to track their payment in real time through every bank in the chain, similar to package tracking. - **Speed**: SWIFT gpi requires that banks process payments within the same day they are received. As a result, nearly 50% of SWIFT gpi payments are credited to the beneficiary within 30 minutes, and over 90% within 24 hours. - **Fee transparency**: All fees deducted along the chain are visible to the sender, eliminating the surprise of unexpected intermediary charges. - **Remittance data**: gpi ensures that remittance information (invoice numbers, payment references) is passed through the full chain without being altered or truncated.
Over 4,000 banks have adopted SWIFT gpi, and it now accounts for the majority of cross-border payment value on the SWIFT network.
## SWIFT vs SEPA
SWIFT and SEPA serve different domains. SEPA is a European payment scheme specifically for euro-denominated transfers within 36 European countries. It is fast (1 business day), cheap (free or under €1), and standardized. SWIFT is a global messaging network for payments in any currency between any two countries. It is slower (1-5 days), more expensive ($15-$50+), and involves more complexity.
For euro payments within Europe, SEPA is always the better choice. SWIFT is necessary for payments outside the SEPA zone, payments in non-euro currencies, and payments to countries that are not part of the SEPA network.
## Who Uses SWIFT?
SWIFT is used by banks, financial institutions, corporations, and governments worldwide for international payments. Common use cases include international trade payments, cross-border payroll, foreign direct investment, remittances, and treasury management. For businesses that operate internationally, SWIFT is often the only viable option for large-value cross-border payments, particularly in currencies or corridors not covered by regional payment schemes like SEPA or ACH.
Among payment service providers, Adyen offers SWIFT-based international payouts as part of its platform capabilities, enabling marketplaces and platforms to disburse funds to sellers and partners in countries not covered by local payment methods.
