KR · KRW @ 0.0006580/USD
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.

Rails & infrastructure
The instant rail, the RTGS spine, the card switch, the direct-debit scheme, and the country's CBDC stance. Each rail is reported with operator, launch year, and 2024 flow so the relative scale across rails is readable at a glance.
CBDC status is deliberately granular: live, pilot, preparation, live stalled, and sceptical, no pilot are different things.
BOK's 2020-23 retail CBDC simulation closed without an issuance decision. Project Han-gang Phase 2 launched 18 March 2026 expanded to nine commercial banks testing won-pegged deposit tokens for nationwide retail payments and government subsidy disbursement, with biometric authentication and P2P transfer features. BOK has positioned the asset as 'an intermediate stage between a CBDC and stablecoins'. New governor Shin Hyun-song's April 2026 address centred CBDC and bank tokens; full retail issuance is not premised by the Han-gang work.
Instant payments
KFTC Inter-Bank System (with Open Banking overlay)
The instant leg typically carries the vast majority of retail consumer flow in modern payment systems — and sits in direct tension with card networks and wallets for the same transactions.

RTGS
Real-time gross settlement
The RTGS spine clears high-value interbank flow — including the settlement of the instant-rail cycles and card-network net positions. Transaction count is modest; cleared value is enormous.
