KB Financial Group has successfully completed a proof-of-concept for a won-pegged stablecoin, bringing South Korea one step closer to everyday blockchain payments — even as lawmakers and regulators haggle over the country’s digital asset rulebook.
What KB tested
- Partners: KG Inicis (electronic payments), Kaia (Layer 1 blockchain), and OpenAsset (digital asset solutions).
- End-to-end workflow: the pilot tied together issuance of a won-denominated stablecoin, offline merchant payments, merchant settlements and cross-border remittances — migrating internal settlement onto blockchain while leaving customer-facing services unchanged.
- Real-world demo: consumers paid at a Hollys coffee kiosk with a QR code — no digital wallet installation required — and a blockchain smart contract executed settlement automatically.
- Cross-border test: the won stablecoin was swapped on-chain into a dollar stablecoin using Kaia’s liquidity, then routed through a Vietnam partner to the recipient’s bank account. The transfer completed in under three minutes and reportedly cut fees by about 87% compared with traditional methods.
Why it matters
KB says the trial shows how “digital financial services closely integrated into daily life” can be built by combining trusted financial infrastructure with blockchain. The bank also said it aims to be ready to roll out services once South Korea finalizes the legal and regulatory framework for digital assets.
Regulatory roadblock
Stablecoins are central to South Korea’s digital asset plans, but key legislation has stalled for months. The second phase of the Virtual Asset User Protection Act (the Digital Assets Act) was expected before the end of 2025, yet disagreement between the Financial Services Commission (FSC) and the Bank of Korea (BOK) has held things up since December.
At issue is the proposed role of banks in issuing stablecoins. The BOK wants any approved issuer to be majority-owned (at least 51%) by a consortium of banks. The FSC counters that such a requirement could squeeze out tech firms and stifle innovation.
Voices from the field
- Lawmakers have urged the National Assembly to prioritize stablecoin legislation, warning that while Korea debates governance, the global market advances.
- Professor Ahn Soo-hyun (Hankuk University of Foreign Studies) pointed out last week that South Korea — which accounts for roughly 10% of global digital asset transactions — risks falling behind as other jurisdictions refine crypto rules.
- At a recent Korea Chamber of Commerce and Industry forum, industry leaders called the stablecoin framework a “critical juncture” for the country.
- BOK Deputy Governor Chang Cheong-soo said the won-pegged stablecoin “could serve as a complementary and competitive payment method in future monetary systems,” helping in virtual asset transactions and cross-border payments.
Bottom line
KB Financial’s pilot demonstrates practical benefits — faster settlements, lower fees and a smooth, wallet-free customer experience — reinforcing the real-world case for won-pegged stablecoins. But widespread adoption hinges on regulatory clarity: until South Korea resolves the bank-versus-tech governance debate and passes the Digital Assets Act, commercial rollouts will remain on hold.
