South Korea’s Leading Bank Launches Cross-Border Payment Solutions for Kinexys
KB Kookmin Bank is poised to launch a blockchain-powered cross-border payment service targeted at import and export businesses in August 2026.
Overview
- Initially, KB Kookmin will provide Kinexys-based U.S. dollar payments to ten countries starting August 2026.
- This service merges blockchain settlement with SWIFT, facilitating corporate transfers outside traditional banking hours.
- KB is the first South Korean financial institution to employ Kinexys for corporate import and export payments.
The South Korean bank aims to utilize Kinexys by J.P. Morgan to enable U.S. dollar payments spanning ten nations.
This service will connect Kinexys with the current SWIFT system, facilitating nearly immediate transfers and foreign exchange settlements throughout the day. Customers can access this service via KB Kookmin Bank’s domestic branches and its Singapore branch.
KB Kookmin leads as the first Korean bank to implement Kinexys
KB Kookmin Bank announced its agreement with J.P. Morgan regarding blockchain remittance services on July 26. As noted by Yonhap News Agency, this initiative will mark the first instance of a South Korean financial entity utilizing Kinexys for payment services aimed at import and export firms. The agreement focuses on increasing the speed of cross-border remittances for businesses engaged in overseas trade, supplier payments, and foreign exchange settlements.
The initial phase will concentrate on U.S. dollar transactions. Supported markets include South Korea, the U.S., Singapore, Saudi Arabia, India, Thailand, Qatar, the United Arab Emirates, Bahrain, and South Africa. The bank has yet to reveal customer fees, transaction limits, or a precise launch date in August.
Kinexys connects blockchain settlement with existing banking systems
J.P. Morgan describes Kinexys as a bank-led blockchain platform for payments, asset tokenization, and near-immediate settlements. The network operates continuously, allowing approved institutions to transfer funds without the constraints of traditional banking hours. Previously known as Onyx, it has broadened its functionality.
The KB service won’t replace SWIFT; rather, it will integrate Kinexys with existing messaging and correspondent banking systems. This strategy allows banks to leverage blockchain for quicker movement and settlement while upholding current compliance guidelines, account structures, and foreign exchange processes.
J.P. Morgan has expanded Kinexys’ reach into various markets. In June, the bank unveiled blockchain deposit accounts in multiple currencies including Australian dollars, Hong Kong dollars, Japanese yen, Chinese yuan, and Singapore dollars. This expansion supports eight currencies, enabling 24/7 payments, programmable treasury functionalities, and on-chain foreign exchange.
Other financial institutions have already harnessed the platform for corporate payments. Qatar National Bank adopted Kinexys for U.S. dollar transactions in 2025, allowing corporate transfers beyond regular banking hours and significantly reducing certain settlement times to minutes.
KB accelerates its institutional blockchain endeavors
This payment initiative builds on various blockchain efforts within KB Financial Group. In June, KB Kookmin Bank successfully executed a $100 million digital bond issuance using HSBC’s Orion platform. This two-year U.S. dollar bond was settled in just three business days, compared to five days under previous processes.
KB Kookmin is also involved in South Korea’s tokenized deposit initiatives. The Ministry of Economy and Finance has appointed nine banks, including KB, for a project connecting tokenized deposits to government spending systems. The upcoming pilot aims to implement programmable conditions alongside a shared record of public payments.
Additionally, KB Kookmin Card has been developing a payment system that merges stablecoins with traditional credit. As per reports by Crypto.news, this project utilizes the Avalanche and OpenAsset infrastructure, allowing users to transact from stablecoin wallets while maintaining standard card settlements for merchants.
Major banks are integrating blockchain into operational payment services
KB Financial Group has been recognized as South Korea’s largest lender by assets, according to S&P Global Market Intelligence’s 2026 Asia-Pacific bank review, ranking 28th in the region with approximately $552.76 billion in assets. This substantial scale provides the bank with a robust corporate network to launch the new service.
This launch further contributes to the widespread adoption of tokenized deposits and blockchain settlements. In May, J.P. Morgan, Mastercard, Ripple, and Ondo Finance conducted a cross-border Treasury redemption experiment. Kinexys managed the payment orders and U.S. dollar settlements, while the tokenized asset facilitated transactions on the XRP Ledger.
Furthermore, J.P. Morgan has implemented Kinexys in collaboration with entities such as Axis Bank, Mitsubishi Corporation, and EBANX. In July, EBANX reported that the platform reduced certain internal cross-border transaction times from over 24 hours to mere minutes by removing local cutoff restrictions.
For KB Kookmin’s corporate clients, the significant change will be the availability of extended operating hours and quicker settlements within certain trade corridors. The bank has not yet outlined plans to add further currencies or countries following the initial phase. The August rollout will clarify how the service integrates with the existing SWIFT processes for commercial payments.
