Cross-Border Payments

Cross-border payments travel over several infrastructure paths depending on currencies, countries, and institutions involved.

‍

The traditional route is correspondent banking: the originating bank transmits a SWIFT message through a chain of correspondent banks until funds reach the destination. Each correspondent deducts fees, applies an FX spread, and forwards the net amount. Total cost is typically 1%–5%; settlement takes 1–5 business days.

‍

Card networks handle cross-border card payments through global authorisation and settlement infrastructure. The issuing bank converts the transaction currency to the cardholder's billing currency, adding a cross-border fee of 0.5%–1.5% to interchange. Settlement is T+1 to T+2.

‍

Alternative rails are growing. Fintech payment networks use local bank accounts in multiple countries to settle cross-border transactions domestically at each end, eliminating the correspondent chain. Payment stablecoins enable USD-denominated transfers settling on blockchain rails in seconds at near-zero cost.

‍

Regulatory compliance is layered: each jurisdiction has its own AML and sanctions requirements; the payment must comply with the rules of the originating country, all intermediary countries, and the destination country.

Cross-border payment costs are a material business problem. The G20 and Financial Stability Board have set targets for cross-border payments, including a global average retail cost of no more than 1% with no corridor above 3%, a benchmark that reflects how far current infrastructure falls short. For businesses with significant international payment volumes, cost and speed improvements translate directly to working capital and margin impact.

‍

E-commerce has dramatically expanded cross-border payment needs. A UK merchant selling to US, European, and Asian customers needs to accept multiple currencies, convert proceeds, and settle without excessive FX and scheme fees on every transaction.

‍

For B2B payments, cross-border friction affects supply chain liquidity. Delayed international supplier payments can disrupt production; high correspondent banking fees erode relationships and margins. The shift to SWIFT GPI, stablecoin rails, and eventual CBDC corridors is partly driven by corporate treasury demand for faster, cheaper execution.
