Cards dominate by value; instant payments have moved from niche to primary rail in under a decade. The RBA's March 2026 Review confirmed a 1 October 2026 ban on card surcharges and a cut in interchange caps to 0.30% wholesale, alongside a new foreign-card interchange cap from April 2027. Contactless is saturated; PayTo is displacing direct debit; CNP fraud remains the headline security problem.
Tab 04
The macro backdrop that actually bends payment behaviour. Nominal GDP, real growth, CPI, policy rate, and FX volatility set the backdrop; interchange, MDR, FX regime, and capital-control posture set the industry-specific dynamics.

Interchange caps
Interchange is the per-transaction fee an acquirer pays an issuer — the floor underneath every MDR merchants see. Domestic caps (where they exist) shape the market far more than individual network schedules.
Regulator · Reserve Bank of Australia
RBA caps are the most aggressive in the G20 and are under active 2026 review. Mandatory least-cost-routing on debit has been extended to mobile wallets (2024 rule change).

Merchant discount rate
The MDR is the fully-loaded cost of card acceptance to the merchant — interchange, scheme fees, and acquirer margin. Small-merchant pricing is routinely 2-3x the large-merchant average.
1.3–1.9% for small business; blended-pricing dominates below A$10m annual volume
