What is SWIFT?

SWIFT (Society for Worldwide Interbank Financial Telecommunication) is a global messaging network that banks use to send secure payment instructions for international transfers. SWIFT itself doesn't move money - it transmits the information banks need to complete cross-border payments.

SWIFT handles critical international banking operations:

• International wire transfers and cross-border payments
• Securities trading and settlement instructions
• Treasury and cash management between multinational subsidiaries
• Trade finance including letters of credit
• Foreign exchange confirmations

Founded in 1973 to replace the unreliable Telex system, SWIFT now connects more than 11,000 financial institutions across 200+ countries. Banks send an average of 42 million SWIFT messages daily, making it the dominant infrastructure for international payment coordination.

SWIFT operates as a member-owned cooperative headquartered in Belgium. Banks elect a 25-member board of directors to govern the organization. The G10 central banks, European Central Bank, and National Bank of Belgium oversee SWIFT's operations.

How SWIFT payments work

A SWIFT payment begins when the sender authorizes their bank to transfer money internationally. The sender provides the recipient's account details, the amount, and the currency.

The sending bank creates a SWIFT message using standardized formats like MT103 (payment instruction), MT202 (interbank transfer), or MT910 (confirmation). This message includes payment details, bank identifiers (SWIFT codes), and routing information. The sending bank transmits the message through the SWIFT network to the receiving bank.

If the banks have no direct relationship, the message routes through one or more correspondent banks. 75% of SWIFT payments involve intermediary banks, which adds processing time and fees. Each intermediary validates the message, applies compliance checks, and forwards it to the next bank in the chain.

The receiving bank gets the SWIFT message, performs its own compliance checks, converts currency if needed, and credits the recipient's account. Settlement happens through separate channels between the banks involved, not through SWIFT itself.

SWIFT processing times and costs

SWIFT transfers vary significantly in speed and cost depending on the banks involved and the payment corridor.

Processing times:

• Average processing time: 18 hours 18 minutes based on analysis of 2,000 transactions
• 66% of payments arrive within 24 hours
• Standard range: one to five business days for full settlement
• Transfers with intermediary banks: average 1 day 11 hours
• Direct bank-to-bank transfers: average 15 hours
• Weekend and holiday timing extends processing - Friday transfers may not complete until Tuesday

Transaction costs:

• Sending bank fee: $35-$50 for outgoing international transfers
• Intermediary bank fees: $10-$25 per intermediary (deducted from transfer amount)
• Receiving bank fee: $10-$15 to process incoming payments
• Currency conversion markup: 1%-3% on the exchange rate
• 75% of payments involve intermediary banks, which multiplies fees

SWIFT vs other payment rails

SWIFT dominates international bank transfers but faces competition from faster, cheaper alternatives.

SWIFT processes through correspondent banking networks over one to five business days. Instant payment rails like FedNow (domestic US) and SEPA Instant (Europe) settle in seconds. For cross-border payments, stablecoin infrastructure combines instant settlement with costs 5-10x lower than SWIFT.

SWIFT's advantages include universal bank coverage, established trust, and support for all major currencies. Every significant bank globally connects to SWIFT, making it reliable for reaching any destination. SWIFT handles both small consumer transfers and multi-million dollar corporate transactions.

The disadvantages center on cost, speed, and transparency. Multiple intermediaries create opacity - the sender often doesn't know the exact fees or how much the recipient will receive. SWIFT has been criticized for inefficiency, with transfers passing through multiple banks before reaching their destination.

Common SWIFT use cases

SWIFT enables diverse cross-border financial operations. Here are the primary ways institutions use the network:

• International wire transfers: Consumers and businesses use SWIFT to send money across borders. A company paying an overseas supplier initiates a SWIFT transfer through their bank. The payment travels through the SWIFT network to the supplier's bank, settling the invoice in the supplier's local currency.
• Securities trading: Investment banks and brokers use SWIFT to settle cross-border securities transactions. When an investor buys foreign stocks or bonds, SWIFT messages coordinate the delivery of securities and payment between the trading parties.
• Treasury operations: Multinational corporations use SWIFT to move money between subsidiaries in different countries. A parent company might use SWIFT to transfer funds for working capital, dividend payments, or cash pooling across its global operations.
• Trade finance: Banks use SWIFT to issue and manage letters of credit for international trade. The messages coordinate document exchange, payment terms, and compliance requirements between importers, exporters, and their respective banks.
• Correspondent banking: Banks maintain relationships with correspondent banks to service customers in countries where they don't operate. SWIFT messages coordinate these correspondent banking arrangements, enabling global reach without physical presence.

SWIFT codes and identification

Every institution on the SWIFT network receives a unique identifier called a SWIFT code or BIC (Bank Identifier Code). These codes are 8 or 11 characters long and specify the bank, country, and location.

The first four characters identify the bank. The next two specify the country code using ISO standards. Characters seven and eight indicate the location or city. Optional characters nine through eleven designate a specific branch.

For example, BOFAUS3N is Bank of America's SWIFT code. BOFA identifies the bank, US indicates United States, 3N specifies New York. SWIFT codes appear on bank statements and are required to receive international transfers.

SWIFT alternatives and competition

While SWIFT remains dominant, alternative networks serve specific regions and use cases.

China's CIPS (Cross-border Interbank Payment System) launched in 2015 to internationalize the yuan. CIPS handles RMB-denominated transactions between 1,467 institutions across 111 countries. Russia developed SPFS (System for Transfer of Financial Messages) after facing SWIFT exclusion threats.

Emerging payment infrastructure challenges SWIFT's model. Stablecoin networks enable instant cross-border settlement without correspondent banks. Real-time payment rails like SEPA Instant connect directly between countries at lower cost. These alternatives offer speed and cost advantages but lack SWIFT's universal coverage and regulatory acceptance.

For fintech operators, choosing between SWIFT and alternatives depends on use case requirements. SWIFT provides maximum reach and regulatory compliance for traditional banking relationships. Alternative rails offer better economics and speed for specific corridors or for businesses comfortable with newer infrastructure.
