Methodology
Each corridor figure models the total cost of a US$10,000 business transfer — flat fees plus the FX margin over the interbank mid-market rate, combined into a single % of principal.
Bank wire: published correspondent-bank wire fees (sending, intermediary and receiving) plus the average retail bank FX margin for the currency pair`s liquidity tier. Corridors requiring double conversion (e.g. NGN→USD→CNY) carry both margins.
Modern rails: typical licensed fintech pricing routing through domestic instant-payment systems (NIBSS, GhIPSS, PesaLink, UPI, CIPS, NAPAS and peers) with wholesale FX.
Stablecoin: USDT/USDC settlement including on-ramp and off-ramp spreads and network fees, via regulated partners.
Figures are indicative estimates refreshed quarterly, intended for comparison between routing methods and corridors — not as a quote. For a live, bookable rate use the KeyBS Pay quote engine. Corridor detail pages: Global Payouts hub.
