In a recent analysis, South Korea’s fiscal oversight body highlighted the transformative potential of stablecoins for the nation’s retail sector. The report suggests that if merchants across the country adopt stablecoins as a regular payment method, they could collectively save as much as $3.8 billion each year. This figure stems from a combination of reduced transaction fees, lower currency conversion costs, and the elimination of many of the intermediaries that traditionally inflate the price of electronic payments.

Stablecoins are digital assets that aim to maintain a stable value by being pegged to a fiat currency, a basket of assets, or an algorithmic mechanism. Because they are designed to avoid the volatility that characterises most cryptocurrencies, they are increasingly being viewed as a practical bridge between traditional finance and the emerging world of blockchain‑based payments. For South Korean merchants, the appeal lies in the ability to receive payments that are instantly settled, transparent, and less costly than conventional card‑based systems that often charge merchants between 1.5 and 3 percent per transaction, not to mention additional fees for cross‑border processing.

The budget office’s calculations take into account the average annual sales volume of small‑ and medium‑sized enterprises (SMEs) in South Korea, which constitute the backbone of the country’s economy. By switching to stablecoins, these businesses could bypass the traditional banking infrastructure that currently acts as a credit intermediary. In a typical transaction, a merchant’s bank not only processes the payment but also extends short‑term credit, holds the funds for a settlement period, and charges a spread for these services.

Stablecoin transactions, by contrast, settle on a blockchain within seconds, removing the need for the bank’s credit function and the associated costs. However, the fiscal watchdog also issued a cautionary note about the broader financial implications of a rapid shift toward stablecoins. One of the primary concerns is that banks could see a significant erosion of their role as credit intermediaries. Banks traditionally assess credit risk, provide loans, and manage liquidity for both consumers and businesses.

If merchants increasingly rely on stablecoins for payments, the volume of funds flowing through traditional banking channels could decline, potentially reducing banks’ capacity to lend. This could have a cascading effect on the overall credit availability in the economy, especially for sectors that depend heavily on bank financing. Another risk highlighted in the report concerns the stability of the stablecoin pegs themselves. While stablecoins are engineered to maintain a one‑to‑one relationship with a reference currency—most commonly the U.S.

dollar—this peg is only as robust as the reserves or mechanisms backing it. In a scenario where a large number of users attempt to redeem their stablecoins for fiat currency simultaneously—a “mass redemption” event—the peg could come under pressure. If the issuer of the stablecoin does not have sufficient liquid reserves, or if market confidence wanes, the token could deviate from its intended value, leading to financial losses for merchants and consumers alike. To mitigate these risks, the budget office recommends a series of regulatory and supervisory measures.

First, it suggests that stablecoin issuers be required to hold transparent, audited reserves that match the total supply of tokens in circulation. This would provide a clear audit trail and reassure users that redemption can be fulfilled at any time.

Second, the office calls for the establishment of a supervisory framework that monitors the systemic impact of stablecoin adoption on the banking sector, ensuring that credit intermediation does not become overly constrained. In addition to regulatory safeguards, the report emphasizes the importance of education and infrastructure development. Merchants need clear guidance on how to integrate stablecoin payment gateways into their existing point‑of‑sale systems, as well as training on best practices for managing digital wallets and safeguarding private keys.

The government could play a pivotal role by offering subsidies or tax incentives for early adopters, thereby accelerating the diffusion of the technology while allowing time for the financial system to adjust. From a macroeconomic perspective, the potential savings of $3.8 billion represent a notable boost to South Korea’s competitiveness. Lower transaction costs can translate into lower prices for consumers, higher profit margins for businesses, and increased disposable income that can be redirected toward consumption or investment. Moreover, the adoption of stablecoins could position South Korea as a leader in the integration of blockchain‑based financial services, attracting fintech talent and encouraging innovation in related sectors such as digital identity verification, smart contracts, and decentralized finance (DeFi).

In conclusion, while stablecoins offer a compelling avenue for South Korean merchants to reduce operational costs and streamline payments, the transition must be managed carefully. Policymakers need to balance the economic benefits with the potential disruption to traditional banking functions and the inherent risks of token peg stability. By implementing robust oversight, encouraging responsible adoption, and fostering a supportive ecosystem, South Korea can harness the advantages of stablecoins while safeguarding the stability of its broader financial system.
