South Korea’s recent decision to halt its innovative CBDC pilot—Project Han River—is a stark reminder that government-led financial experiments often falter in the face of commercial realities. The Bank of Korea’s (BOK) initial enthusiasm was rooted in the belief that a state-controlled digital currency could modernize the financial ecosystem and enhance monetary sovereignty. However, the mounting costs, lack of a clear path to profitability, and the banks’ outright rejection exposed fundamental flaws in the policymakers’ assumptions. The central bank overestimated its capacity to spearhead a national digital currency, trusting that technology alone could drive adoption. It underestimated the importance of practical business models, consumer demand, and the willingness of financial institutions to shoulder substantial costs for unproven benefits.
The BOK’s attempt to underpin its CBDC with a government-driven project was rooted in a central-related optimism that, as with traditional fiat, state-issued currency should dominate the digital future. But reality struck hard: private banks are primarily profit-driven entities that prioritize sustainable revenue streams over ideological stances on monetary sovereignty. When the banks refused to escalate their investments without a viable profit plan, the project was effectively shelved. The BOK’s decision not to back the program financially beyond a symbolic gesture underscores the original misjudgment of market appetite and operational risks involved.
The Rise of Private Stablecoins: An Uncontrollable Power Shift
In the wake of the CBDC suspension, the private financial sector has responded assertively, forming a formidable consortium to launch its own stablecoin solutions pegged to the Korean won. This strategic pivot signals a broader shift: private entities see an opportunity to shape the digital currency landscape to their advantage, positioning themselves as the primary arbiters of digital liquidity within the country. Rather than relying on the state’s slow-moving and often risk-averse approach, commercial banks like KB Kookmin and Shinhan have taken proactive steps—registering trademarks, developing technical proofs-of-concept, and mobilizing resources—to deploy their own stablecoins.
This move is motivated not only by profit but also by the imperative to preempt disintermediation caused by emerging fintech competitors and foreign dollar-pegged cryptocurrencies. The banks’ initiative aims for a quick rollout by late 2025 or early 2026, utilizing their extensive customer bases to capture revenue streams through digital token offerings. The underlying logic is straightforward: control the means of digital exchange, and profits follow. This strategic shift demonstrates that the private sector views stablecoins as the new storefront for financial dominance—an end-run around state-controlled monetary frameworks that could compromise macroeconomic stability.
Government Policy: From Skepticism to Support, But at What Cost?
The political landscape in Korea has shifted toward a more crypto-friendly stance, especially under President Lee Jae-myung, whose campaign platform openly embraced stablecoins and digital assets. The impending “Digital Asset Basic Act” exemplifies this ideological pivot. Granting primary regulatory authority to the Financial Services Commission (FSC) rather than the Bank of Korea signifies a deliberate decentralization of control that favors private entrepreneurs. The act’s low capital requirement of ₩500 million ($370,000) is a calculated move to lower entry barriers, encouraging rapid proliferation of stablecoin issuers at the expense of oversight and risk management.
This regulatory environment invites a highly competitive atmosphere, where large banks are preemptively staking strong claims. Their trademark filings—like KB Kookmin’s 17 proposed stablecoin tickers—are not just symbolic but strategic, aiming to secure exclusive rights in an emerging market. Shinhan’s previous experiments with international remittances using stablecoins further exemplify a readiness to seize opportunities rather than wait for bureaucratic processes. There is a clear message: private sector innovation, not government-led control, will define Korea’s digital money future.
The Risks of an Unregulated Wild West
While private stablecoins promise flexibility and rapid deployment, they also pose systemic risks that cannot be ignored. The central bank’s warnings about unrestrained private issuance echo past crises such as Terraform/Luna, which demonstrated how unregulated digital assets can destabilize financial markets. The recent surge in USD-pegged stablecoin transactions—over Т₩56.95 trillion in just the first quarter of 2025—indicates a growing dependence on foreign currency proxies. This volume suggests that market players are increasingly favoring assets outside the control of local monetary authorities, challenging the sovereignty and stability of the Korean won.
By framing its suspended CBDC efforts as a “countermeasure,” the BOK reveals its own discomfort with losing control, yet the truth is that private stablecoins are already shaping the financial narrative. Their proliferation risks creating a dual-currency environment that complicates monetary policy, increases capital flight, and amplifies systemic vulnerabilities. The government’s cautious stance—favoring regulation and controlled phasic expansion—may be insufficient to contain this developing chaos. Private institutions, motivated by profit and competitive advantage, are rapidly outpacing regulatory safeguards, creating an unpredictable landscape that could threaten Korea’s economic stability.

Note: This critique emphasizes the dangers of private sector dominance over public monetary policy and argues that Korea’s current trajectory hints at a future where financial stability could be compromised by unrestrained innovation driven by profit motives rather than systemic safety.
