KB Kookmin Bank touches Kinexys. Why is partnership important for blockchain payments?

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 JP Morgan’s blockchain payment network for transactions.
Summary
- KB Kookmin Bank plans to launch South Korea’s first Kinexys powered blockchain payment service for corporate exchanges next month.
- The service will initially support the transfer of US dollars to 10 countries through the bank’s branches in Korea and Singapore.
- The launch builds on KB Kookmin’s recent Blockchain initiatives, including the issuance of a $100 million digital bond and a stablecoin payment card project with Avalanche.
- JP Morgan’s Kinexys offers programmable payments and real-time settlement to institutional clients using blockchain technology.
South Korea’s Yonhap News Agency reported that KB Kookmin Bank plans to launch the service in partnership with JP Morgan’s Kinexys, with the rollout scheduled for next month.
According to the report, the bank will be the first financial institution in the country to adopt a blockchain payment network to accommodate import and export companies.
KB Kookmin Bank brings Kinexys to corporate payments
The upcoming service will be provided by KB Kookmin Bank’s domestic operations in South Korea and the Singapore branch, according to Yonhap. When launched, the bank plans to prioritize US 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 JP Morgan’s blockchain business that provides structured payments, asset tokenization and near-real-time payments to institutional clients. By connecting to the network, corporate customers will be able to process payments for cross-border transactions using the blockchain infrastructure instead of relying entirely on traditional settlement systems.
The report did not disclose transaction limits or the categories of businesses that will gain access during the first phase. It also did not specify whether additional funds or countries would be added after the initial release.
For KB Kookmin Bank, the planned launch adds another production deployment to the blockchain strategy that has gradually expanded across payments, fundraising and digital financial infrastructure rather than always being limited to pilot projects.
Previous blockchain projects have included fundraising
The latest payment system follows another blockchain milestone completed by the bank earlier this year.
In June, KB Kookmin Bank completed the issuance of a $100 million digital bond, becoming the first South Korean bank to raise foreign currency financing through distributed ledger technology, according to previous local media reports.
The two-year US dollar bond was privately placed in Hong Kong and traded at the Secured Overnight Financing Rate, or SOFR, plus 0.4 basis points. HSBC acted as sole bookrunner, while issuance was carried out on Orion, the bank’s digital asset platform.
According to the bank, blockchain technology supports the entire bond lifecycle, including issuance, registration, trading and settlement. The new structure shortened the settlement from five business days under normal procedures to three business days. A bank official told local media at the time that the approach simplified operational processes while reducing the risk of default.
The lender described the transaction as a practical use of blockchain technology in raising capital rather than a proof of concept, placing it among the first blockchain fundraising deals completed by a South Korean commercial bank.
Blockchain development within KB Financial Group has been extended to consumer payments.
Earlier this year, KB Kookmin Card announced that it was partnering with Avalanche and OpenAsset to create a hybrid stablecoin credit card system. According to local outlet JoongAng Economy, previously cited by several 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 debited 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 to receive payment through the existing payment infrastructure.
Avalanche is expected to handle the blockchain portion of the system, including stablecoin issuance, wallet transfers and on-chain payments, while KB Kookmin’s traditional card network continues to handle authorization, clearing and merchant payments.
According to previous statements from the bank, customers will continue to receive existing card benefits and rewards programs despite the addition of blockchain payment functionality.
South Korea’s banking sector has increased its adoption of blockchain
Kinexys’ latest partnership also comes as many South Korean financial institutions are experimenting with blockchain infrastructure under regulated frameworks.
Government-backed programs already include 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 bank token deposits for public sector spending, with implementation scheduled for the fourth quarter of 2026.
Nine banks, including KB Kookmin, Shinhan, Woori and Hana, are participating in the program. According to the ministry, the program will link the government’s Digital Budget and Accounting System with a distributed ledger network, which will allow spending situations to be planned in advance while creating an auditable record of public spending.
