Bank of Korea advances CBDC deposit tokens

TLDR

South Koreas central bank is moving its CBDC-based deposit token project from technical trials into larger, real-world banking and payment use.

1. The Bank of Korea (BOK) is scaling Project Hangang so commercial banks can use CBDC-backed deposit tokens for everyday payments, transfers, and even government subsidies.
2. Deposit tokens turn bank deposits into blockchain-based money settled over a wholesale CBDC, sitting between traditional deposits, stablecoins, and a retail CBDC in design and impact.
3. Regulatory clarity and commercialization decisions over the next couple of years will determine how far this model spreads and how it competes with private stablecoins.

Deep Dive

1. What The BOK Is Actually Doing

The BOK has moved its CBDC program, Project Hangang, into live testing with up to 100,000 users making real transactions using deposit tokens backed by a wholesale CBDC held only by banks. In this setup, commercial banks tokenize customer deposits, while the wholesale CBDC is the settlement asset for interbank transfers of those tokens, enabling QR code payments at participating merchants and lower card-fee style costs for retailers.

According to briefing materials and local reporting, the next phase targets a much broader rollout, with plans to expand participants toward 500,000 users, add person to person transfers, auto top ups, and payments at larger merchants, plus pilot government programs like electric vehicle charging subsidies delivered as deposit tokens. These steps push the project from sandbox-style experiments toward an infrastructure that could be run continuously and prepared for full commercialization.

2. Where Deposit Tokens Sit In The Crypto Landscape

Deposit tokens here are digital representations of commercial bank deposits on a ledger, issued by regulated banks but settled over a BOK wholesale CBDC rather than private rails. That differs from classic stablecoins, which are liabilities of non bank issuers backed by reserve assets, and from a pure retail CBDC, which would be a direct liability of the central bank to the public.

For users, the promise is near instant, 24/7 payments, lower merchant fees, and programmable flows such as targeted subsidies. For crypto markets, this model offers bank grade tokenized fiat that can coexist with, and potentially compete against, stablecoins as the default on chain cash, especially in regulated, domestic contexts.

3. Regulation, Commercialization And What To Watch

Despite strong technical progress, Korean regulators are still shaping the legal framework for deposit tokens and won stablecoins, creating a gap between what the BOK can run in pilots and what can be fully commercialized. Banks involved in the project are asking for a long term commercialization roadmap because the expanded pilots require heavy investment in anti money laundering systems, fraud detection, and new compliance processes.

Key signals to watch are: the official size and scope of the next pilot phase, whether deposit tokens enter a regulatory sandbox with clear consumer protection rules, and how rules differentiate bank issued tokens from private KRW stablecoins. Outcomes in Korea will likely inform other jurisdictions that are weighing similar tokenized deposit and CBDC architectures.

Conclusion

The Bank of Korea is turning CBDC backed deposit tokens from a concept into a large scale operational test, positioning tokenized bank money as a serious alternative to both card networks and private stablecoins. How regulators translate these pilots into permanent rules will shape whether this model becomes a core part of on chain money infrastructure or remains a niche, domestic payment rail.
