South Korea’s largest lender, KB Kookmin Bank, is set to introduce a blockchain-based cross-border payment service in August 2026, becoming the first financial institution in the country to leverage J.P. Morgan’s Kinexys platform for commercial payments. The initiative targets corporate import and export customers, initially facilitating U.S. dollar transactions across 10 countries: South Korea, the United States, Singapore, Saudi Arabia, India, Thailand, Qatar, the United Arab Emirates, Bahrain, and South Africa.
The service will integrate Kinexys—a permissioned institutional blockchain supporting real-time settlement and programmable payments—with the existing SWIFT network. This approach preserves payment messaging and compliance procedures while using blockchain for near-instant settlement, operating around the clock. KB Kookmin confirmed the rollout on July 26 following a remittance agreement with J.P. Morgan, though customer fees and transaction limits have not been disclosed.
The move builds on KB Financial Group’s growing blockchain portfolio. In June, the bank completed a $100 million digital bond issuance via HSBC’s Orion platform, shortening settlement from five to three days. It also participates in South Korea’s government-backed tokenized deposit project and earlier this year announced a hybrid stablecoin credit card system with Avalanche and OpenAsset. With approximately $552.76 billion in assets (per S&P Global), KB Kookmin leads institutional adoption of blockchain in the region, mirroring J.P. Morgan’s expansion of Kinexys across multiple currencies and markets—including recent integrations with Qatar National Bank, Axis Bank, and others—that reduce cross-border transfer times from days to minutes.
