SWIFT (Society for Worldwide Interbank Financial Telecommunication) is an international banking communication network designed to allow banks and financial institutions worldwide to exchange transaction information securely and quickly. It is often known as the backbone of the international money transfer system.
Main Roles and Functions:
- Financial Message Transmission: SWIFT provides standardized messaging formats for global financial institutions, handling remittances, payments, foreign exchange transactions, and securities transactions. The messages are used purely to convey information, with the actual movement of funds occurring separately.
- International Standards Provision: SWIFT provides standards like ISO 15022 and ISO 20022 for financial transaction messages. These standards ensure compatibility among national banking systems.
- Security and Reliability: It uses highly encrypted networks to guarantee the confidentiality and integrity of information. Offers real-time error detection and recovery for a reliable messaging environment.
- Identification via SWIFT Code: SWIFT codes, also known as Bank Identifier Codes (BIC), uniquely identify specific financial institutions. Example: "KRBK KR SE" identifies the Bank of Korea.

Structure and Operation:
- Structure:
- Member financial institutions: About 11,000 financial institutions in over 200 countries are part of the SWIFT network.
- Headquarters: Located in Brussels, Belgium, it operates as a neutral, non-profit organization.
- Operating centers: Distributed across various regions, including the US, Netherlands, and Switzerland.
- Operation:
- SWIFT only transmits data, and does not execute or hold financial transactions.
- Financial institutions exchange transaction information via messages over the SWIFT network.
- Fee Structure:
- SWIFT charges fees based on the number of messages sent by financial institutions.
- Fees vary based on message size, type, region, etc.
Structure of a SWIFT Code:
- SWIFT codes can be 8 or 11 characters long and are structured as follows:
- 4 characters: Bank code (e.g., KRBK for Bank of Korea)
- 2 characters: Country code (e.g., KR for Korea)
- 2 characters: Location code (e.g., SE for Seoul)
- 3 characters (optional): Branch code (e.g., 001 for a specific branch)
Advantages:
- Global Financial Network: Connects nearly all financial institutions worldwide, facilitating smooth international transactions.
- Standardization: Standardized transaction message formats allow efficient and reliable information exchange.
- Security: Ensures data security during message transmission using advanced encryption technologies.
Limitations and Controversies:
- Monopolistic Structure: Heavy reliance on SWIFT in international finance means transactions can be halted if specific countries or institutions are excluded.
- Example: Some banks were blocked from the SWIFT network following Russia's invasion of Ukraine in 2022.
- Cost Burden: Transactions using the SWIFT network incur relatively high fees.
- Real-Time Transaction Limitations: SWIFT is a messaging network rather than a real-time transaction system, meaning actual fund transfers can take time.
Alternative Systems to SWIFT:
- China's CIPS: China operates the Cross-Border Interbank Payment System (CIPS) as an alternative to SWIFT.
- TARGET2 in the Eurozone: The European Union processes transactions through its TARGET2 payment system.
Future of SWIFT:
- Integration with Digital Currencies: Exploring the potential of linking with Central Bank Digital Currencies (CBDCs).
- Transition to ISO 20022: Plans to adopt new messaging standards to further enhance the speed and efficiency of financial transactions.
Simple Example: International Remittance via SWIFT:
- Remittance Request: Bank A (Korea) requests a transfer to Bank B (USA) using a SWIFT code.
- Message Transmission: The transaction message is sent to Bank B via the SWIFT network.
- Fund Settlement: Actual funds move through interbank settlement accounts in each country.
