The launch marks a first for a South Korean bank.

According to The Block, KB Kookmin Bank plans to introduce the new service next month under a partnership with Kinexys by J.P. Morgan. The platform will initially support U.S. dollar payments for import and export settlements across 10 countries: South Korea, the United States, Singapore, Saudi Arabia, India, Thailand, Qatar, the United Arab Emirates, Bahrain, and South Africa. The service will be available through the bank's domestic branches as well as its Singapore branch.

Blockchain expands into institutional banking

Kinexys is JPMorgan's blockchain business focused on programmable payments, tokenized assets, and near-real-time settlement for institutional customers. Rather than targeting retail cryptocurrency users, the platform is designed to modernize traditional banking infrastructure by reducing settlement times and improving transaction efficiency.

For KB Kookmin Bank, the partnership represents another step in a broader digital payments strategy. Earlier this year, KB Kookmin Card announced plans to develop a hybrid stablecoin payment model using Avalanche technology, highlighting the group's increasing investment in blockchain-based financial services.

The new cross-border payment platform is expected to streamline international trade transactions for corporate customers by allowing payments to move more efficiently across multiple jurisdictions while operating within existing banking frameworks.

South Korean banks accelerate digital payments

The agreement also reflects wider momentum in South Korea's financial sector. Banks and payment companies are increasingly exploring blockchain infrastructure as regulators become more receptive to tokenized financial services and digital settlement systems.

Payment provider NHN KCP, for example, signed a memorandum of understanding with Ava Labs earlier this year to develop a payments-focused Layer 1 blockchain network. Those initiatives suggest financial institutions are focusing less on speculative digital assets and more on practical applications such as international payments, trade finance, and settlement infrastructure.

As competition intensifies, banks are seeking technologies that reduce transaction costs while improving settlement speed and transparency for corporate clients operating across global markets.

Blockchain moves further into mainstream banking

The rollout demonstrates how blockchain technology is increasingly being adopted behind the scenes of traditional finance rather than replacing it. Large banks are integrating distributed ledger infrastructure into existing payment systems to improve efficiency without changing how customers access banking services.

For JPMorgan, the partnership expands the international reach of Kinexys. For KB Kookmin Bank, it strengthens its position in digital corporate banking as demand grows for faster, always-available cross-border payment services.
