In a recent briefing, South Korea’s budget office highlighted the potential financial impact that stablecoins could have on the nation’s retail sector. According to the office’s projections, if merchants across the country were to adopt stablecoins for everyday transactions, they could collectively save up to $3.8 billion each year.
This figure is derived from an analysis of transaction fees, currency conversion costs, and the inefficiencies inherent in the current banking‑centric payment infrastructure. Stablecoins are a type of cryptocurrency that aim to maintain a stable value by being pegged to a fiat currency, a basket of assets, or an algorithmic mechanism. In the Korean context, the most common reference point is the South Korean won, although many stablecoins are also pegged to the U.S. dollar, which enjoys widespread acceptance in international trade.
By using a digital token that mirrors the value of a stable fiat currency, merchants can bypass several layers of traditional banking that typically add fees and processing delays. The budget office’s report outlines three primary ways in which stablecoins could generate savings for merchants. First, transaction fees associated with credit‑card processing can be substantial, often ranging from 2% to 3% of the sale amount.
Stablecoin payments, by contrast, are processed on blockchain networks where fees are generally lower and more predictable. Second, currency conversion costs are minimized when stablecoins are pegged to the same currency used for the transaction, eliminating the need for costly foreign‑exchange services. Third, the settlement period for stablecoin transfers can be near‑instantaneous, reducing the cash‑flow lag that businesses experience when waiting for bank‑cleared funds. While the financial upside is compelling, the budget office also warned of several systemic risks that could arise from a rapid shift toward stablecoins.
One of the chief concerns is the erosion of banks’ traditional role as credit intermediaries. In the current system, banks evaluate creditworthiness, extend loans, and manage risk across a wide range of borrowers. If merchants begin to rely heavily on stablecoin payments, the volume of cash flowing through banks could diminish, potentially reducing the pool of funds available for lending. This, in turn, could tighten credit conditions for both businesses and consumers, especially in sectors that depend heavily on short‑term financing.
Another risk highlighted in the report relates to the stability of the stablecoin peg itself. Stablecoins maintain their value through a combination of reserves, collateral, and algorithmic controls. In a scenario where a large number of users attempt to redeem their tokens for fiat currency simultaneously—a situation often referred to as a "run"—the underlying reserves could be strained.
If the issuer is unable to meet redemption demands, the token’s value could deviate from its intended peg, leading to market volatility and potential losses for holders. To mitigate these risks, the budget office recommends a series of regulatory measures.
These include requiring stablecoin issuers to hold transparent, fully audited reserves that are readily accessible in the event of mass redemptions. Additionally, the office suggests implementing real‑time monitoring systems that can detect unusual redemption patterns early, allowing authorities to intervene before a systemic shock occurs. The report also calls for close coordination between financial regulators, the central bank, and the technology firms that develop and maintain stablecoin platforms.
From a broader economic perspective, the adoption of stablecoins could have ancillary benefits beyond direct cost savings. By facilitating faster and cheaper cross‑border payments, stablecoins could make South Korean e‑commerce firms more competitive in the global marketplace.
Small and medium‑sized enterprises (SMEs), which often face higher relative transaction costs, could especially benefit from a more efficient payment ecosystem. Moreover, the increased use of blockchain technology could spur innovation in related fields such as supply‑chain tracking, digital identity verification, and smart‑contract‑based automation.
However, the transition to a stablecoin‑centric payment environment will not happen overnight. It will require significant investment in digital infrastructure, education for both merchants and consumers, and a clear legal framework that defines the rights and responsibilities of all parties involved. The budget office emphasizes the importance of a phased approach, starting with pilot programs in select industries or regions, followed by a gradual scaling based on observed outcomes and risk assessments. In summary, the South Korean budget office’s analysis paints a nuanced picture of stablecoins’ potential.
On one hand, the technology promises substantial cost reductions—up to $3.8 billion annually—for merchants who adopt it, along with faster settlement times and reduced reliance on traditional banking fees. On the other hand, it raises legitimate concerns about credit intermediation, peg stability, and the need for robust regulatory oversight. By balancing innovation with prudent risk management, South Korea could position itself at the forefront of the next wave of digital finance, leveraging stablecoins to enhance economic efficiency while safeguarding the stability of its financial system.
