Airwallex plugged into Australian interbank rails

This was the move that let Airwallex act like a bank before it had built a bank sized network. By plugging into Australian interbank rails, Airwallex could send money through domestic bank infrastructure instead of routing everything through SWIFT and correspondent banks. That cut out multiple middlemen, got it closer to mid market FX pricing, and gave early export heavy customers a much cheaper way to collect from overseas buyers and pay suppliers abroad.

• In practice, the product was simple. A merchant funded Airwallex locally in Australia, Airwallex used bank partners and local clearing to move money into destination markets, then added about a 0.2% margin on top of cheaper wholesale FX. That is how it could beat legacy B2B FX providers by 50% to 80% on total fees.

• This is the same playbook later used by modern cross border fintechs. Build local bank access first, then replace partner dependence with owned accounts and direct local payout capability. Airwallex now says 93% of transactions run outside SWIFT, which shows how far it has moved from bank assisted routing to its own internal network.

• The customer shape explains why this mattered. Airwallex had relatively few customers doing very large volumes, about $1M per customer at $100B TPV in 2024, versus Wise Business at about $66K and Payoneer at about $15K. Large marketplace and platform customers care a lot about shaving even small percentages off FX and payout costs.

The next phase is less about winning a single transfer and more about becoming the default money movement layer inside other software. As Airwallex expands cards, embedded payouts, and platform APIs, every new volume stream makes its internal network denser, lowers unit costs further, and strengthens the advantage that began with those early bank rail partnerships.
