Stablecoins May Help South Korean Retailers Cut Up to $3.8 Billion Annually, According to Budget Office

In a recent analysis released by South Korea’s budget office, officials highlighted the considerable financial upside that stablecoins could offer to the nation’s retail sector. By leveraging these digital assets, merchants across the country stand to slash operating costs dramatically—potentially saving as much as 3.8 billion US dollars each year.

The projection is based on a series of assumptions about how stablecoins would be integrated into everyday commerce, ranging from point‑of‑sale transactions to cross‑border payments and supply‑chain financing. ### How Stablecoins Cut Costs for Merchants Stablecoins are a class of cryptocurrencies designed to maintain a stable value, usually by being pegged to a fiat currency such as the US dollar or the Korean won. Because their price does not swing wildly like Bitcoin or Ethereum, they can be used much like traditional cash for everyday purchases. The budget office’s model suggests that merchants could benefit in three primary ways: 1.

**Lower Transaction Fees**: Conventional card networks charge merchants anywhere from 1.5 % to 3 % per transaction, plus additional fixed fees. Stablecoin payments, by contrast, are processed on blockchain networks that can settle transactions for a fraction of a cent.

Even after accounting for the modest gas fees associated with major public blockchains, the overall cost per transaction can be reduced by a factor of ten or more. 2.

**Faster Settlement Times**: Credit‑card settlements typically take one to three business days to clear, tying up working capital and requiring merchants to manage short‑term liquidity. Stablecoin transfers settle within minutes, and in some layer‑2 solutions, even seconds. This immediacy allows retailers to reinvest funds almost instantly, improving cash flow and reducing the need for expensive short‑term financing.

3. **Reduced Currency‑Conversion Overheads**: South Korean merchants who sell to overseas customers often face multiple conversion steps—first from the buyer’s currency to a local one, then to the Korean won.

Stablecoins that are pegged to a globally recognized currency can act as a universal bridge, eliminating the need for multiple foreign‑exchange transactions and the associated spreads. When these savings are aggregated across the nation’s roughly 2.5 million registered retailers, the cumulative effect becomes substantial. The budget office’s estimate of $3.8 billion in annual savings reflects a scenario where stablecoins capture a modest 10 % of total retail transaction volume—a figure that could rise as consumer confidence and regulatory clarity improve.

### Potential Risks Highlighted by the Budget Office While the financial upside is compelling, the budget office also warned about several systemic risks that could arise from a rapid shift toward stablecoins: - **Erosion of Banks’ Credit‑Intermediation Role**: Banks traditionally serve as the middlemen that collect deposits and extend credit to businesses. If merchants bypass banks by receiving payments directly in stablecoins, the volume of deposits that banks can leverage for lending may shrink.

This could constrain credit availability for small and medium‑sized enterprises that rely on bank loans for inventory purchases, expansion, or payroll. - **Peg Stability Under Stress**: Stablecoins maintain their peg through a combination of collateral reserves, algorithmic mechanisms, or a mix of both. In a scenario where a large number of users attempt to redeem their stablecoins for fiat simultaneously—a so‑called “run”—the underlying reserves could be tested. If the issuer cannot meet redemption demands, the peg could break, leading to a sudden devaluation that would hurt both merchants and consumers holding the tokens.

- **Regulatory Ambiguity**: South Korea’s financial regulator is still shaping its approach to digital assets. Unclear or rapidly changing rules could create compliance headaches for merchants, especially those that operate across multiple jurisdictions. The budget office emphasized the need for a clear, consistent regulatory framework that protects consumers while fostering innovation. ### Mitigation Strategies and Policy Recommendations To balance the benefits with the risks, the budget office suggested several policy measures: 1.

**Strengthening Stablecoin Oversight**: Require issuers to maintain transparent, regularly audited reserve accounts and to disclose their peg‑maintenance mechanisms. This would boost confidence among merchants and reduce the likelihood of a destabilizing run. 2. **Encouraging Bank‑Stablecoin Partnerships**: Rather than viewing stablecoins as a competitor, banks could act as custodians or liquidity providers for stablecoin transactions.

Such collaborations would allow banks to retain a role in credit intermediation while offering merchants the efficiency of digital payments. 3. **Gradual Implementation**: Pilot programs in specific sectors—such as tourism, e‑commerce, or logistics—could provide real‑world data on cost savings and operational challenges. Lessons learned can then inform broader rollout strategies.

4. **Consumer Protection Measures**: Implement clear dispute‑resolution processes for stablecoin transactions, ensuring that merchants and buyers have recourse in cases of fraud or technical failures. ### Broader Implications for the Korean Economy If the projected savings materialize, the ripple effects could be far‑reaching.

Lower operating costs would likely translate into lower prices for consumers, enhancing purchasing power and potentially stimulating demand. Moreover, the increased efficiency could make South Korean retailers more competitive on the global stage, particularly in e‑commerce where speed and cost are critical differentiators.

On the macroeconomic front, a shift toward stablecoins could also influence the country’s payment‑system architecture. The Bank of Korea has already been exploring a central‑bank digital currency (CBDC), and the coexistence of a CBDC with privately issued stablecoins could create a layered digital‑currency ecosystem.

Properly managed, this ecosystem could improve financial inclusion, offering unbanked or underbanked populations a reliable means of transacting. ### Conclusion The budget office’s report paints a picture of both opportunity and caution. Stablecoins have the potential to unlock billions of dollars in savings for South Korean merchants by slashing transaction fees, accelerating settlement, and simplifying cross‑border payments.

However, the transition must be managed carefully to avoid undermining banks’ traditional credit‑intermediation function and to safeguard the stability of the tokens themselves. By instituting robust oversight, fostering collaboration between banks and stablecoin issuers, and rolling out the technology through measured pilots, South Korea can harness the efficiency of stablecoins while preserving financial stability. The path forward will require coordinated effort among regulators, financial institutions, technology providers, and the merchants themselves, but the payoff—significant cost reductions and a more modernized payment landscape—could be well worth the effort.
