South Korea Expands Digital Won Pilot with Tokenized Deposit Trials

The Bank of Korea is set to broaden its CBDC pilot program, introducing regional financial institutions and testing the distribution of government subsidy payments through tokenized bank deposits. This expansion marks a significant step in the country’s multi-year effort to modernize its financial infrastructure using distributed ledger technology.

As part of this upcoming phase, Busan Bank and Jeonbuk Bank will join the existing roster of participating commercial lenders. The inclusion of these regional players is intended to test the technical feasibility of a digital currency ecosystem beyond the major national banks based in Seoul. By integrating Busan Bank and Jeonbuk Bank, the central bank aims to ensure that the digital won can operate seamlessly across different banking tiers and geographic regions.

A primary focus of the new trials involves the issuance and circulation of tokenized bank deposits. Unlike a direct retail CBDC, which represents a claim on the central bank, tokenized deposits are digital versions of traditional commercial bank holdings recorded on a shared ledger. This model is increasingly favored by global financial regulators because it preserves the existing two-tier monetary system while introducing the efficiencies of blockchain, such as instant settlement and programmability.

The pilot will specifically explore the use of “purpose-bound” money. This feature allows the government to issue subsidies that can only be spent at designated merchants or for specific services. By utilizing tokenized bank deposits for government subsidy payments, the state can potentially reduce administrative overhead, minimize fraudulent claims, and ensure that welfare funds are used as intended. This mirrors similar experiments conducted by the Bank for International Settlements (BIS) regarding the future of programmable finance.

Technical testing will also extend to consumer-facing applications. Participants in the trial will be able to make purchases using QR code payments, a method already deeply integrated into South Korea’s highly digitized retail sector. The central bank is working closely with the Financial Services Commission and the Financial Supervisory Service to establish a robust legal and regulatory framework for these digital assets.

South Korea’s push toward a digital currency comes as central banks worldwide accelerate their own research. According to data from the BIS, over 90% of central banks are currently exploring CBDCs in various stages. South Korea is particularly well-positioned for this transition due to its exceptionally high rate of non-cash transactions and advanced mobile telecommunications infrastructure. The Financial Services Commission has previously emphasized that any digital currency implementation must prioritize financial stability and consumer protection while fostering innovation in the fintech sector.

The upcoming phase follows earlier wholesale-level tests that focused on interbank settlements. By moving toward retail-adjacent use cases like subsidies and merchant payments, the Bank of Korea is moving closer to a comprehensive assessment of whether a digital won is necessary for the nation’s long-term economic security.
