KB Kookmin Bank has expanded its blockchain strategy by preparing to launch a Kinexys-powered cross-border corporate payment service next month, becoming the first South Korean bank to use J.P. Morgan’s blockchain payment network for trade settlements. Summary KB Kookmin Bank plans to launch South Korea’s first Kinexys powered blockchain payment service for corporate trade settlements next month. The service will initially support U.S. dollar cross border transfers across 10 countries through the bank’s Korean and Singapore branches. The launch builds on KB Kookmin Bank’s recent blockchain initiatives, including a $100 million digital bond issuance and a stablecoin payment card project with Avalanche. Kinexys by J.P. Morgan provides programmable payments and near real time settlement for institutional clients using blockchain technology. South Korea’s Yonhap News Agency reported that KB Kookmin Bank plans to introduce the service through a partnership with Kinexys by J.P. Morgan, with the rollout scheduled for next month. According to the report, the bank will become the country’s first financial institution to adopt the blockchain payment network for corporate import and export settlements. KB Kookmin Bank brings Kinexys to corporate payments The upcoming service will be offered through KB Kookmin Bank’s domestic operations in South Korea as well as its Singapore branch, according to Yonhap. At launch, the bank plans to prioritize U.S. dollar transfers involving 10 countries: South Korea, the United States, Singapore, Saudi Arabia, India, Thailand, Qatar, the United Arab Emirates, Bahrain and South Africa. Kinexys is J.P. Morgan’s blockchain business that provides programmable payments, asset tokenization and near-real-time settlement for institutional clients. By connecting to the network, corporate customers will be able to process cross-border trade payments through blockchain infrastructure instead of relying entirely on conventional settlement systems. The report did not disclose transaction limits or the categories of businesses that will receive access during the initial phase. It also did not specify whether additional currencies or countries will be added after the first rollout. For KB Kookmin Bank, the planned launch adds another production deployment to a blockchain strategy that has gradually expanded across payments, fundraising and digital financial infrastructure rather than remaining limited to pilot programs. Earlier blockchain projects have covered fundraising The latest payment initiative follows another blockchain milestone completed by the bank earlier this year. In June, KB Kookmin Bank completed a $100 million blockchain-based digital bond issuance, becoming the first South Korean bank to raise foreign-currency funding through distributed ledger technology, according to previous local media reports. The two-year U.S. dollar-denominated bond was privately placed in Hong Kong and priced at the Secured Overnight Financing Rate, or SOFR, plus 0.4 percentage points. HSBC served as the sole bookrunner, while the issuance was carried out on Orion, the bank’s digital asset platform. According to the bank, blockchain technology supported the entire bond lifecycle, including issuance, registration, trading and settlement. The new structure shortened settlement from five business days under conventional processes to three business days. A bank official told local media at the time that the approach simplified operational procedures while reducing settlement default risk. The lender described the transaction as a practical application of blockchain technology for capital raising instead of a proof-of-concept exercise, placing it among the first production-grade blockchain fundraising deals completed by a South Korean commercial bank. Blockchain development within KB Financial Group has also extended into consumer payments. Earlier this year, KB Kookmin Card announced that it was working with Avalanche and OpenAsset to build a hybrid stablecoin credit card system. According to local outlet JoongAng Economy, cited previously by multiple industry publications, the design allows users to connect a blockchain stablecoin wallet to an existing credit card. Under the patented payment structure, purchases are first deducted from the customer’s stablecoin wallet. If the available balance is insufficient, the remaining amount is automatically charged to the linked credit card while merchants continue receiving settlement through existing payment infrastructure. Avalanche is expected to manage the blockchain portion of the system, including stablecoin issuance, wallet transfers and on-chain settlement, while KB Kookmin’s traditional card network continues handling authorization, clearing and merchant payouts. According to earlier statements from the bank, customers will continue receiving existing card benefits and reward programs despite the addition of blockchain payment functionality. South Korea’s banking sector has increased blockchain adoption The latest Kinexys partnership also arrives as more South Korean financial institutions experiment with blockchain infrastructure under regulated frameworks. Government-backed initiatives have already included KB Kookmin Bank among participating institutions. Earlier this year, South Korea’s Ministry of Economy and Finance selected a regulatory sandbox project that will use tokenized bank deposits for public-sector spending, with implementation planned for the fourth quarter of 2026. Nine banks, including KB Kookmin, Shinhan, Woori and Hana, are participating in that program. According to the ministry, the system will connect the government’s Digital Budget and Accounting System with a distributed ledger network, allowing spending conditions to be programmed in advance while creating an auditable record of public fund usage.
