Project Hangang: Wholesale CBDC and Deposit Tokens

The Bank of Korea is advancing a major digital currency initiative called Project Hangang, designed to modernize Korea's payment and settlement infrastructure through blockchain-based wholesale CBDC and commercial bank-issued deposit tokens.

Project Architecture

Wholesale Layer: Central Bank Digital Currency (CBDC) for interbank settlement

Enables high-speed, low-cost settlement
Reduces settlement risk and operational complexity
Positions for international payment integration

Commercial Layer: Bank-issued deposit tokens

Won-pegged stablecoins issued by participating commercial banks
Backed by CBDC reserves held at the Bank of Korea
Enables retail transactions while maintaining central bank oversight

Current Phase (Phase 2) – Real-World Pilot

Launch Timeline: Phase 2 began March 2026

Participating Banks (9 total):

KB Kookmin
Shinhan Bank
Woori Bank
Hana Bank

Peer-to-peer (P2P) transfers between customers (Phase 1 enhancement)
Government subsidy disbursements
Large-scale corporate and merchant payments
Transaction cost reduction for small merchants (credit card fee elimination)
Consumer-to-business and business-to-consumer transactions

Use Cases in Phase 2

Government Subsidy Distribution: Testing direct disbursement of government subsidies in digital form, starting with electric vehicle (EV) charging infrastructure subsidies in H1 2026.

Merchant Payment Integration: Addressing merchant pain points by reducing credit card processing fees, particularly benefiting small merchants and SMEs.

Controlled private sector participation
Central bank oversight and monetary policy integration
Consumer protection through regulatory framework
Potential future integration with international payment systems

Regulatory Context

The broader deployment of KRW-pegged stablecoins and digital currency infrastructure in Korea is governed by the Digital Asset Basic Act, which remains under development with ongoing disputes regarding stablecoin issuance authority. The BoK's wholesale CBDC and deposit token framework is designed to operate in parallel with evolving stablecoin regulation.

Future Roadmap

Requires verification from official sources Planned future phases may include:

Expansion of deposit token participation to additional commercial banks
Integration with real-time gross settlement (RTGS) infrastructure
