A South Korean insurer and a major Japanese financial group have pulled off something neither institution had tried before: moving digital money across the Japan-Korea border without ever touching the U.S. dollar. Kyobo Life Insurance and Japan’s SBI Group announced on Sept. 17 that they had completed a cross-border stablecoin pilot testing direct exchange between yen- and won-denominated stablecoin representations, according to Yonhap. The Korea Japan stablecoin pilot ran on test infrastructure rather than live money, but it offers an early look at how two of Asia’s biggest financial markets might eventually settle cross-border payments without routing through dollar-denominated intermediaries.
Key takeaways
- Kyobo Life Insurance and SBI Group completed a pilot that tested direct yen-won stablecoin exchange, avoiding a U.S. dollar conversion step, running from July through the Sept. 17 announcement.
- The project used the Canton Network test environment to simulate institutional fund transfer, foreign exchange, and settlement between Japan and South Korea.
- Only test tokens were used; no real stablecoins or institutional funds changed hands during the exercise.
- Kyobo Life described it as South Korea’s first cross-border institutional stablecoin test by an insurer, a characterization not yet validated by any regulator.
- SBI is separately building Project Musubi, a Japan-Korea stablecoin payment network with Korean firm Nodeinfra, distinct from the Kyobo Life pilot.
Kyobo Life and SBI Group complete cross-border stablecoin pilot
The pilot modeled a transaction path where a yen-denominated stablecoin could be swapped directly for its won-denominated counterpart, cutting out the usual intermediate step of converting yen into dollars and then dollars into won. That structural choice is the whole point of the exercise: it’s a test of whether two currencies can talk to each other on a shared settlement layer without a third currency acting as translator.
Kyobo Life said the project had been running since July in partnership with SBI Digital Practice, SBI’s blockchain-focused subsidiary. The companies used test tokens representing yen and won stablecoins rather than production assets, and reporting from Financial News and TokenPost confirmed that no real institutional funds or live stablecoins were transferred at any point. In practice, this means the pilot proved a technical route works, not that a commercial version is ready to launch.
Kyobo Life billed the exercise as South Korea’s first cross-border institutional stablecoin test conducted by an insurance company. That claim comes directly from Kyobo Life itself and hasn’t been confirmed or endorsed by a regulator, so it should be read as a company characterization rather than an established industry record.
What the test actually measured
During the run, the two firms checked how transaction data could be tracked and verified in real time, and how digital assets arriving from overseas would be processed and settled once inside South Korea. Kyobo Life said the results demonstrated the “technical feasibility and efficiency” of stablecoin-based institutional transfers, arguing that fewer currency-conversion steps could shorten processing time and lower transaction costs. The company did not publish any figures quantifying those savings, so the efficiency claim remains qualitative for now.
Canton Network infrastructure underpins the pilot
The entire exchange ran on Canton Network, a blockchain built specifically for regulated financial institutions that need configurable privacy and permission controls when moving assets and settlement data. That design matters because insurers and banks generally can’t operate on fully public blockchains where transaction details are visible to anyone.
SBI has been leaning into Canton as the backbone of its institutional blockchain push. Back in July, SBI Holdings renamed its subsidiary SBI Security Solutions to SBI Digital Practice, tasking the unit with building financial infrastructure and applications on Canton. The retooled group now covers settlement, tokenized securities, and stablecoin-related projects under one roof.
Canton has already drawn other financial players into similar experiments. Visa and Brale tested stablecoin settlement on the network to see whether institutions could settle on-chain without exposing sensitive transaction data publicly. Separately, South Korea’s Shinhan Asset Management and Shinhan Investment & Securities have each struck their own cooperation deals tied to Canton for exploring tokenized Korean assets and overseas market access, signaling that adoption of the infrastructure among Korean institutions extends well past this one pilot.
Implications and future developments
Why does a yen-won pilot without real money matter? Because it tests the plumbing before anyone commits actual capital. If institutions can prove that a direct currency swap works technically, the case for skipping a dollar-conversion leg in cross-border settlement becomes easier to make to regulators and boards alike. That’s a meaningful step even without hard numbers on cost or time savings.
The Kyobo Life pilot isn’t the only Japan-Korea stablecoin effort in motion. SBI Digital Practice and Nodeinfra, a South Korean blockchain infrastructure company, signed a separate agreement in August to develop Project Musubi, a payment network intended to support yen- and won-denominated settlement on Canton Network. Project Musubi is built around payment-versus-payment settlement and distributed netting, with SBI Digital Practice connecting Japanese financial institutions and Nodeinfra developing settlement protocols on the Korean side. The initial phase, like the Kyobo Life pilot, will rely on test tokens before any shift toward regulated commercial stablecoins.
These two efforts shouldn’t be confused with one another. The Kyobo Life test began in July and focused narrowly on one insurer’s institutional transfer model, while Musubi was announced separately in August as a broader network-development program with a different Korean partner. Both point toward the same destination — a working Japan-Korea stablecoin corridor — but they are distinct tracks moving at their own pace.
There’s also a capability gap worth watching. SBI’s yen-side infrastructure is considerably further along than South Korea’s won-side framework. Earlier in 2026, the company rolled out its yen-pegged JPYSC stablecoin via SBI Shinsei Trust Bank, subsequently broadening its application to lending and tokenized-asset initiatives. Then on Sept. 7, SBI disclosed that a portion of the trust assets underpinning JPYSC had started being channeled into Japanese government bonds — an operational milestone that South Korea’s won-denominated stablecoin market has yet to reach.
South Korea, for its part, is still working out a complete legal framework for won-backed stablecoins. The Bank of Korea has continued to favor bank-led issuance, while lawmakers remain split over the country’s broader digital asset legislation. Private-sector pilots like this one have kept moving forward regardless, which suggests companies are positioning themselves for whatever regulatory framework eventually lands rather than waiting for it to be finalized.
FAQ
What was the scope of the Kyobo Life and SBI stablecoin pilot?
The pilot tested direct exchange between yen- and won-denominated stablecoin representations without converting through U.S. dollars, using Canton Network in a simulated institutional fund transfer.
Did the pilot involve real institutional funds or stablecoins?
No, the pilot used test tokens representing stablecoins, and no real institutional funds or stablecoins were transferred.
What is Canton Network and how was it used in the pilot?
Canton Network is a blockchain infrastructure for regulated financial institutions offering privacy and permission controls. It was used to simulate fund transfer, foreign exchange, and settlement processes.
What are the regulatory implications of this pilot?
South Korea has not yet finalized a legal framework for won-backed stablecoins, favoring bank-led issuance, while Japan’s SBI has a more developed yen stablecoin infrastructure.
