South Korea's largest bank will process U.S. dollar payments across 10 countries using J.P. Morgan's blockchain platform, keeping SWIFT for compliance. Fees and exact date are not yet disclosed.
Blockchain-based cross-border payments will go live at KB Kookmin Bank in August 2026, making South Korea's largest lender the first domestic bank to use J.P. Morgan's Kinexys platform for commercial services.
The system will handle U.S. dollar transactions across 10 countries – South Korea, the United States, Singapore, Saudi Arabia, India, Thailand, Qatar, the UAE, Bahrain, and South Africa – while keeping existing SWIFT messaging and compliance in place. Blockchain will settle the payments; the rest of the infrastructure stays the same.
KB Kookmin announced the service on July 26 after signing a blockchain remittance agreement with J.P. Morgan. The bank has not disclosed fees, transaction limits, or the exact August launch date.
Kinexys already supports eight currencies. In June, J.P. Morgan added blockchain deposit accounts in Australian dollars, Hong Kong dollars, Japanese yen, Chinese yuan, and Singapore dollars, enabling round-the-clock payments and programmable treasury functions.
The payment launch follows a string of digital-asset projects across KB Financial Group. In June, KB Kookmin issued a $100 million digital bond through HSBC's Orion platform, using blockchain for issuance, registration, trading, and settlement. The two-year U.S. dollar bond settled in three business days instead of five.
KB Kookmin also participates in a government-backed tokenized deposit pilot. South Korea's Ministry of Economy and Finance selected nine banks, including KB Kookmin, to test tokenized deposits linked to public-sector spending in the fourth quarter of 2026. The project connects the government's Digital Budget and Accounting System to a distributed ledger that records transactions and lets the government program spending conditions.
Earlier this year, KB Kookmin Card said it would develop a hybrid stablecoin credit card system with Avalanche and OpenAsset. The design lets customers spend stablecoins from blockchain wallets, with a traditional credit line kicking in automatically if wallet balances run short.
KB Kookmin held about $552.76 billion in assets, the top spot among 28 South Korean banks in S&P Global Market Intelligence's 2026 Asia Pacific bank review.
The bank's payment service lands as institutional blockchain settlement picks up speed. J.P. Morgan, Mastercard, Ripple, and Ondo Finance recently tested cross-border U.S. Treasury redemption on the XRP Ledger, using Kinexys to process payment instructions and settle in dollars while the tokenized asset moved on the ledger. J.P. Morgan has also brought Kinexys to Qatar National Bank, Axis Bank, Mitsubishi Corporation, and EBANX. EBANX said in July that the platform cut cross-border transfer time from over 24 hours to minutes.
