South Korea Prepares Second Phase of CBDC Pilot for September Launch

The Bank of Korea is preparing to launch the second phase of its central bank digital currency (CBDC) pilot as early as September, expanding both the scope of testing and the number of participating institutions.

According to reports, the next phase will bring two additional regional banks into the fold, broadening the pilot beyond the initial group of financial institutions that participated in phase one. The expansion signals that Korea's central bank is moving from experimental infrastructure tests toward real-world payment scenarios.

What the New Phase Covers

The second phase is expected to test several new capabilities:

  • Retail payments using tokenized bank deposits, allowing consumers to make purchases with digital won issued through commercial bank intermediaries
  • Government subsidy disbursements routed through the CBDC infrastructure, a use case that several central banks have identified as a high-value application for programmable money
  • Cross-institution interoperability, with the two new regional banks testing how well the system handles transactions across different intermediaries

The decision to incorporate government subsidy payments is notable. Programmable central bank money can enforce spending conditions automatically — for example, ensuring that a housing subsidy can only be used for housing-related expenses. Several countries, including China and India, have explored similar functionality in their own digital currency initiatives.

Tokenized Deposits Take Center Stage

Korea's approach leans heavily on a two-tier distribution model: the central bank issues the CBDC, but commercial banks distribute it to end users. This is consistent with how most central banks are designing their systems, as it preserves the role of commercial banks in the financial system and avoids the risk of disintermediation.

The pilot will use tokenized bank deposits — digital representations of commercial bank money that settle on infrastructure provided or overseen by the central bank. This is distinct from a pure retail CBDC, where consumers hold claims directly against the central bank. Tokenized deposits have gained traction among policymakers because they offer many of the benefits of digital currency — faster settlement, programmability, transparency — while keeping commercial banks in the payments chain.

Regional Context

South Korea is one of several Asian economies aggressively pursuing CBDC development. The People's Bank of China has been running its own e-CNY pilot for years, with varying degrees of adoption. Japan's central bank has been more cautious but has signaled increased interest in digital currency experiments. Singapore's Project Orchid has explored purpose-bound money through tokenized deposits.

Korea's pilot stands out for its methodical pace. Rather than rushing to a full launch, the Bank of Korea has taken an incremental approach — testing infrastructure, then adding use cases, then expanding participants. The September phase represents the most ambitious expansion yet in terms of real-world functionality.

Why It Matters

CBDC development has accelerated globally over the past two years, driven by concerns about falling behind in payments innovation, the potential erosion of monetary sovereignty, and the rise of private stablecoins. Korea's pilot is one of the most closely watched in the developed world, partly because the country has one of the highest rates of digital payment adoption and a banking system that is technically sophisticated.

The addition of subsidy payments to the test scope is a meaningful step. If successful, it demonstrates that CBDC infrastructure can handle more than just retail payments — it can serve as a platform for government fiscal policy, with potential efficiency gains over traditional disbursement methods.

The September launch timeline suggests the Bank of Korea is comfortable enough with the underlying technology to begin testing in production-adjacent environments. Whether this leads to a full retail CBDC launch remains an open question, but the trajectory is clear: Korea is building the rails, one phase at a time.
