South Korea’s central bank isn’t just talking about tokenization anymore. It’s building the infrastructure.
Bank of Korea Governor Shin Hyun-song took the stage at the ECB Forum on Central Banking in Sintra, Portugal on June 30, presenting a paper titled “A unified ledger in practice: lessons from Project Hangang.” The core argument: tokenizing government bonds on a single permissioned ledger could fundamentally simplify how sovereign debt gets issued, settled, and managed.
What Project Hangang actually does
Project Hangang is the Bank of Korea’s flagship experiment in building what it calls a Digital Currency System, or DCS. The platform is permissioned, meaning it’s not an open blockchain anyone can join. It’s a controlled environment run by the central bank, designed to host tokenized central bank money, commercial bank deposits, and other tokenized assets on one unified ledger.
The key technical concept here is atomic settlement. When a bond trade happens, the exchange of the asset and the payment occurs simultaneously and automatically, with no gap between delivery and payment.
Phase I of the project ran from April to June 2025 and involved roughly 80,000 users and 12,000 merchants. Phase II is scheduled to begin in the second half of 2026, expanding the system’s capabilities.
Governor Shin’s paper emphasized that the system preserves the “two-tier monetary structure” — the existing arrangement where central banks issue base money and commercial banks create deposits on top of it. The DCS uses tokenized wholesale central bank digital currency as the settlement asset while keeping commercial banks in the loop.
South Korea’s regulatory momentum
South Korea’s Financial Services Commission is expected to release tokenized-securities guidelines in July 2026, creating a regulatory framework that would sit alongside the BOK’s technical infrastructure.
Governor Shin’s vision also aligns with broader international efforts. The Bank for International Settlements has been championing cross-border interoperability through Project Agorá, which explores how tokenized financial systems in different countries could communicate with each other.
One notable absence from the paper: any mention of public crypto tokens or specific blockchain technologies. The BOK is interested in the tokenization concept, not the crypto ecosystem that popularized it.
What this means for investors
The broader competitive landscape is worth watching. Singapore’s Monetary Authority has been running its own tokenization experiments. The European Central Bank hosted this very forum where Shin presented, and has its own Appia project. And the BIS is actively building frameworks for cross-border token interoperability. South Korea’s combination of a completed Phase I, a Phase II launching in the second half of 2026, and incoming regulatory guidelines from the FSC in July 2026 puts it near the front of the pack.
For the crypto industry specifically, the signal is mixed. Central banks adopting tokenization validates the core thesis that blockchain-style infrastructure can improve financial markets. However, projects like Hangang are explicitly designed to operate outside the public crypto ecosystem, using permissioned systems, central bank-issued settlement assets, and regulated participants.
