KB Kookmin Bank Launches Blockchain-Based Overseas Remittance Service Using JPMorgan's 'Kinexys'

Starting in August 2026, KB Kookmin Bank will begin a corporate overseas remittance service utilizing Kinexys, a blockchain platform by JPMorgan. This move by KB Kookmin Bank, which boasts the largest asset scale in South Korea, signifies a transition toward a 24/7 digital financial infrastructure that transcends the limitations of traditional financial networks.

This service is designed to allow import and export companies to perform near real-time dollar settlements 24/7 without the complex intermediary procedures of the past. It is interpreted as a strategic attempt to resolve the delays and cost issues inherent in existing SWIFT-based legacy systems.

According to foreign media outlets such as Yonhap News and Cointelegraph, KB Kookmin Bank officially announced the launch plan for this service on July 26, 2026. The service primarily targets import and export corporate clients engaged in international trade and focuses on resolving clearinghouse delay issues in the existing financial sector.

Kinexys is a blockchain-based payment system created in late 2024 when JPMorgan rebranded its existing 'Onyx' platform. The platform operates as a permissioned blockchain, providing institutional participants with high security and a regulatory-compliant environment.

Technical Capabilities and Scale of Kinexys Infrastructure

Currently, Kinexys' cumulative transaction volume has exceeded $4 trillion, with an average daily transaction volume reported to be over $7 billion. This large-scale transaction processing capability was a decisive factor in KB Kookmin Bank joining the global financial network.

• Introduction of a direct settlement method that bypasses traditional correspondent banks and clearinghouses
• Support for 24/7/365 uninterrupted real-time remittance and settlement
• Reduction in operating costs through the automation of fund transfer processes
• Enhanced transaction transparency and traceability through blockchain technology

Through this partnership, KB Kookmin Bank now stands alongside global financial institutions such as Qatar National Bank (QNB) and EBANX. The addition of KB Kookmin Bank, one of the largest banks in Asia, is expected to further solidify the influence of the Kinexys network in the Asian market.

On June 29, 2026, J.P. Morgan expanded its global payment network by adding support for currencies such as the Japanese Yen, Chinese Yuan, and Singapore Dollar on Kinexys. KB Kookmin Bank plans to focus on U.S. Dollar (USD) remittances initially, with plans to increase supported currencies in line with future market conditions.

Regulatory and Strategic Implications for the Korean Financial Market

The introduction of this service will serve as an opportunity to establish KB Kookmin Bank as a leader in the field of 'global digital payments' within the Korean financial sector. Given the trade-dependent structure of the Korean economy, the establishment of an efficient trade settlement system is a matter directly linked to national financial competitiveness.

Looking ahead, KB Kookmin Bank is keeping the possibility open for integration with tokenized assets and commercial bank-issued digital currencies (CBDC), beyond simple remittances. According to a research report by J.P. Morgan, blockchain technology like Kinexys has significant potential to evolve into core infrastructure that supports the private issuance and operation of central bank digital currencies.

The traditional SWIFT network had the disadvantages of incurring fees through multiple intermediary banks and taking several days for settlement. By eliminating these intermediate steps, the Kinexys platform helps companies manage their cash flow more predictably.

Large corporations and asset managers such as Siemens and BlackRock are already participating in the Kinexys ecosystem, proving the efficiency of blockchain-based payments. KB Kookmin Bank's participation is expected to serve as an important bridge for Korean companies to keep pace with these global standards.
