South Korea's Shinhan Card has joined forces with Japan's SBI Group to explore blockchain-based payments and cross-border settlements under a new financial partnership that could eventually allow Japanese travelers to make everyday purchases in South Korea with yen-backed stablecoins. The initiative is designed to connect digital assets with traditional payment systems while improving transaction efficiency.

Shinhan and SBI Launch Stablecoin Payment Initiative

Shinhan Card announced the agreement on October 21, following a signing ceremony held in Tokyo on October 20. The partnership involves two SBI Group subsidiaries: SBI VC Trade and SBI XDC APAC.

The companies will run proof-of-concept trials covering card-linked stablecoin payments, wallet-to-wallet transfers, and international trade settlements. They will also examine potential participation in the XDC Network ecosystem, which supports blockchain-based financial transactions.

Under the proposed system, Japanese visitors would be able to spend yen-denominated stablecoins through familiar card payment channels. Tourists could, for example, potentially pay at South Korean restaurants or stores without directly managing conventional currency exchanges.

Stablecoins are digital tokens pegged to a fiat currency — in this case, the yen — allowing holders to spend a familiar unit of value over blockchain rails. The tourist-facing concept also addresses a substantial travel corridor: Japan ranks among the largest sources of inbound visitors to South Korea.

Blockchain Payments Could Streamline Cross-Border Transfers

Beyond tourism, the collaboration will investigate stablecoin transfers between digital wallets and businesses operating across national borders. The partners aim to determine whether blockchain technology can reduce settlement delays and improve efficiency compared with traditional international payment networks.

That comparison matters because conventional cross-border payments typically pass through chains of correspondent banks and can take several business days to settle — the friction these token-based trials are designed to test against.

Security remains a central consideration. Before any broader implementation, the companies plan to evaluate anti-money laundering procedures and fraud detection systems.

The project is still in its testing stage. The partners have not announced a commercial launch date, nor have they identified the specific yen stablecoin that would support the proposed payment services.

Growing Institutional Interest in Stablecoin Infrastructure

The agreement reflects mounting interest among Asian financial institutions in integrating stablecoins into mainstream payment infrastructure. Shinhan Financial Group previously partnered with Visa in August to explore digital assets and artificial intelligence-powered financial services. SBI, for its part, has expanded its digital asset initiatives through partnerships involving stablecoin settlements and blockchain infrastructure, and its latest collaboration with Shinhan could provide another practical testing environment for these technologies.

The regulatory backdrop also differs across the two markets: Japan has operated a licensing framework for fiat-backed stablecoins since its revised Payment Services Act took effect in 2023, while South Korea is still shaping dedicated stablecoin legislation.

Successful trials could eventually offer travelers more convenient payment options while helping businesses streamline international transfers. Nevertheless, commercial adoption will depend on technical performance, regulatory compliance, and effective integration with existing financial systems. For now, the Shinhan-SBI partnership represents another step toward connecting traditional banking services with blockchain-based payments across Japan and South Korea.
