Summary
The dollar stablecoin OUSD (Open USD) has brought 140 companies worldwide on board as partners. Among them are 13 South Korean firms, including Samsung Electronics, Shinhan Financial Group, KB Kookmin Card, and Dunamu. At the core of the model is a structure that distributes reserve-management income — traditionally monopolized by the issuer — to partner companies. But for this partnership to translate into real profit, another door must still open: Korea's regulatory environment.
What Happened
A structural flaw in the dollar stablecoin market has long drawn criticism. Issuers keep the entire income generated from reserves invested in dollars, U.S. Treasuries, and similar assets for themselves, while coin holders and ecosystem partners are excluded outright. Tether's net profit disclosed last year — which topped $13 billion — is a direct product of this structure.
OUSD is launching with a design intended to extend this income structure across the entire ecosystem. Samsung Electronics' participation stands apart from the other partners in that it represents a hardware-payment ecosystem touchpoint — it signals a pathway for Samsung Pay, embedded in Galaxy devices, to operate on stablecoin rails. Shinhan Financial Group and KB Kookmin Card are aiming to serve as a bridge connecting existing won-based payment networks with the dollar stablecoin. Dunamu is expected to play a liquidity-provision and on/off-ramp role through Upbit.
Structural Background
Underlying this trend is the ongoing U.S. legislative debate over stablecoins. With the GENIUS Act passing the U.S. Senate, the mainstream regulatory integration of dollar stablecoins has come into clearer view. Once the law takes effect, reserve-holding requirements, audit standards, and licensing frameworks will be codified, and only coins that meet these standards will gain access to global payment networks. Signing on as a partner now is not simply marketing — it is positioning to secure a stake within the ecosystem before the regulatory framework is finalized. Korea's regulatory landscape is different: even after the Virtual Asset User Protection Act took effect, the Financial Services Commission has yet to finalize the legal classification standard for stablecoins. This regulatory uncertainty is precisely the piece the market has not yet priced in.
Stock (Ticker) and Industry Sector Impact
- Samsung Electronics (005930): Joins as the only hardware-and-platform operator capable of grafting stablecoin rails onto a Galaxy-device-based payment ecosystem. This is less about a short-term stock (ticker) price reaction and more about opening a mid-to-long-term fintech monetization pathway. Expect a lag of at least several quarters after service launch before the revenue model becomes visibly reflected in earnings.
- Shinhan Financial Group (055550): Shinhan Financial Group has the most direct exposure to fee-structure changes in dollar payments, foreign exchange, and trade finance. Having maintained a comparatively fast-moving position on digital asset services among domestic financial holding companies, it stands a relatively high chance of a real benefit once regulations are clarified.
- KB Financial Group (105560): Its subsidiary KB Kookmin Card has joined as a partner. It is exposed to the expansion of dollar-payment-accepting merchants and to changes in foreign-exchange margin structures, and experiments linking the card payment network with stablecoins could affect long-term fee structures.
- Kakao (035720): Holds a stake in the unlisted Dunamu, creating an indirect path to benefit from the expansion of the OUSD ecosystem. The key variable is the scale of revenue Dunamu earns from providing liquidity.
- Fintech and Blockchain Infrastructure: Expansion of the stablecoin ecosystem comes with demand for KYC, AML, and payment-processing solutions. Domestic fintech infrastructure solution providers fall within the group of indirect beneficiaries.
Bull vs. Bear Scenarios
Bull Scenario: If the Financial Services Commission issues stablecoin service guidelines within the year following the GENIUS Act taking effect, dollar stablecoin service launches by domestic financial firms become a reality. As long as the high-interest-rate environment persists, the scale of reserve-income distribution stays meaningful, keeping the business model attractive. It also cannot be ruled out that the network effect of the 140 partner companies could erode some of the entrenched dominance of USDT and USDC.
Bear Scenario: If the Financial Services Commission strictly classifies stablecoins as virtual assets, the domestic service launch gets delayed. If the Federal Reserve enters a rate-cutting cycle, reserve-management yields themselves decline, shrinking the scale of income distribution that is OUSD's core differentiator. The network effects and incumbent-defense strategies of USDT and USDC remain a valid barrier to entry for a late mover.
Investor Action Points
- Track the timing of the Financial Services Commission's stablecoin regulatory guidelines. This is the primary trigger that will determine the service-launch roadmap for domestic financial stocks.
- Check the timeline for the U.S. GENIUS Act's presidential signature and effective date. Once the law takes effect, dollar stablecoin standards will go global, creating conditions for Korean policy to move faster as well.
- Watch interest-rate direction in parallel. The Federal Reserve's benchmark interest rate level directly determines the scale of OUSD's reserve-income distribution. The lower rates go, the more this business model's unit economics are diluted.
- After OUSD actually launches, check quarterly trading volume and the number of partner-service integrations. Partnership announcements get priced into the stock (ticker) in advance, but trading volume is what proves the revenue model — the gap between these two figures will determine the next direction for the stock (ticker) price.
