Two financial groups in East Asia have completed a proof-of-concept exercise designed to show how stablecoins might one day support institutional payments between Japan and South Korea without routing money through the US dollar.
SBI Digital Practice, a subsidiary of Japan’s SBI Holdings (TYO: 8473) focused on Canton Network projects, worked with Kyobo Life Insurance, one of South Korea’s leading life insurers and an equity-method affiliate of SBI Holdings, to test the full workflow of a cross-border transfer.
The trial, which ran from July and was announced on September 17, 2026, used test tokens rather than live funds or commercially issued stablecoins.
On the Canton Network test environment, a token modeled on a yen-denominated stablecoin was sent from Japan, exchanged for a token representing a won-denominated stablecoin, and received in South Korea.
The exercise covered institutional fund movement, foreign-exchange conversion, settlement, real-time tracking of transaction data, and the operational steps a Korean insurer would need to accept and hold digital assets arriving from overseas.
Traditional correspondent-banking routes between the two countries typically convert yen into dollars and then dollars into won.
That process can involve several intermediaries, extra fees, delayed settlement, and additional foreign-exchange exposure.
The pilot was intended to examine whether a direct yen-to-won token swap could shorten those steps and lower costs.
Both companies said the test confirmed that such a structure is technically feasible and could, if later commercialized under appropriate regulation, reduce processing time and simplify conversion.
Kyobo Life described the project as the first time a South Korean insurance company has verified an end-to-end institutional cross-border transfer, exchange, and settlement process using this type of digital-token model.
For SBI Digital Practice, the work fits a broader effort to connect regulated institutions to blockchain infrastructure for settlement, tokenized assets, and stablecoin use cases.The two groups already have a long-standing relationship.
SBI Holdings first invested in Kyobo Life in 2007 and, together with SBI Digital Asset Holdings, signed a strategic digital finance partnership with the Kyobo group in 2024 that included research on security-token issuance and distribution.
The latest pilot is presented as an extension of that collaboration rather than a standalone experiment.
No live stablecoins changed hands and no commercialization timetable was announced.
Regulatory frameworks for digital assets and stablecoins in both Japan and South Korea will need further development before similar transactions can move from a test environment into production.
Even so, the companies indicated they will continue exploring ways to link digital asset exchange, settlement, and asset-management activities between the two markets and to study new crypto-related financial services.
The exercise illustrates a wider regional interest in building payment rails that do not automatically rely on the dollar as an intermediary currency.
For insurers and other large institutions that regularly move funds across the Japan–Korea corridor, a working model of direct stablecoin settlement could eventually offer faster finality and clearer audit trails.
It remains to be seen now if that potential is realized. It will most likely depend on future regulation, operational readiness, and the willingness of additional counterparties to join similar networks.
