South Korea has the most card-intense consumer economy in the G20: credit-card spending alone runs at roughly 90% of nominal GDP, supported by a three-decade policy stack of tax credits for card use, mandatory acceptance and subsidised merchant pricing. Super-app wallets (KakaoPay, Naver Pay, Toss) sit on top of cards as their settlement backbone rather than displacing them. Project Han-gang's Phase 2 went live in March 2026 with nine banks testing won-pegged deposit tokens, while the new BOK governor has publicly prioritised CBDC and bank tokens over stablecoins.
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.

Korea has the most actively-managed merchant fee regime among OECD markets. FSC conducts a triennial review setting mandatory SMB fee caps tiered by merchant annual revenue; enforcement via Credit Finance Business Act.

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.
