Kyobo Life Insurance and Japan’s SBI Group have completed a cross-border pilot testing direct exchange between yen- and won-denominated stablecoin representations, routing institutional transfers without converting funds through the U.S. dollar.
Yonhap, citing Kyobo Life on Sept. 17, reported that the project had run since July with SBI Digital Practice and used the Canton Network test environment to model institutional fund transfer, foreign exchange and settlement between Japan and South Korea. No actual institutional money or live stablecoins moved during the demonstration.
Kyobo Life called the project South Korea’s first cross-border institutional stablecoin test conducted by an insurance company — a characterization that comes from the insurer itself rather than from a regulator.
Cutting out the dollar leg
The pilot modeled a transaction route in which a yen-denominated stablecoin could be exchanged directly for a won-denominated stablecoin, avoiding an intermediate conversion from yen into U.S. dollars and then from dollars into won. That two-step dollar detour is how most cross-border institutional flows settle today, and each hop adds time, cost and counterparty exposure.
The companies used test tokens inside Canton Network rather than production stablecoins. Reporting from Financial News and TokenPost confirmed the exercise did not transfer real stablecoins or institutional funds, limiting the result to a technical and operational demonstration.
Even so, Kyobo Life said the test covered the complete sequence of moving institutional funds across borders, including exchange and settlement. During the exercise, the companies examined how transaction information could be checked and tracked in real time, and tested procedures for handling digital assets arriving from overseas and processing related settlement activity inside South Korea.
Kyobo Life said the test demonstrated the technical feasibility and efficiency of stablecoin-based institutional transfers, arguing that fewer currency-conversion steps could reduce processing time and transaction costs — though the company did not publish comparative figures quantifying those savings.
Canton Network as the institutional rails
The pilot ran on Canton Network, a blockchain infrastructure designed for regulated financial institutions that need configurable privacy and permission controls when exchanging assets and settlement information. That privacy model is precisely what makes it attractive to insurers and banks that cannot expose transaction details on public ledgers.
SBI Digital Practice has made Canton a central pillar of its institutional blockchain strategy. In July, SBI Holdings renamed SBI Security Solutions as SBI Digital Practice, saying the subsidiary would focus on building financial infrastructure and applications on Canton Network — spanning settlement, tokenized securities and stablecoin-related projects.
Canton has appeared in other financial-sector stablecoin tests as well. Visa and Brale tested stablecoin settlement on the network while examining whether institutions could complete on-chain settlement without exposing sensitive transaction information publicly. In South Korea, Shinhan Asset Management and Shinhan Investment & Securities have entered cooperation arrangements involving Canton to study tokenized Korean assets and access to overseas markets.
Separate from Project Musubi — but pointing the same direction
The Kyobo Life pilot sits beside a separate SBI project announced in August with South Korean blockchain infrastructure company Nodeinfra. The two companies agreed to develop Project Musubi, a Japan-Korea payment network intended to support yen- and won-denominated settlement on Canton Network, starting with test tokens before any move to regulated commercial stablecoins.
Project Musubi is designed around payment-versus-payment settlement and distributed netting. SBI Digital Practice is responsible for connecting Japanese financial institutions and existing systems, while Nodeinfra develops settlement protocols and supports participating Korean institutions. The Kyobo test and Musubi should not be conflated — one was a July-starting institutional transfer demonstration with an insurer, the other an August network-development program — but both target the same direct yen-won corridor.
The asymmetry between the two countries is instructive. SBI launched the yen-denominated JPYSC through SBI Shinsei Trust Bank earlier in 2026 and has expanded its use into lending and tokenized-asset initiatives. On Sept. 7, SBI said part of the trust assets backing JPYSC had begun being invested in Japanese government bonds. South Korea, by contrast, remains in the process of defining a complete legal framework for won-backed stablecoins, with the Bank of Korea and lawmakers still negotiating the boundaries of a regime.
The Kyobo pilot suggests Korean institutions are not waiting for the domestic framework to mature before testing the plumbing. By demonstrating direct won-yen settlement inside a permissioned environment, the insurer has built operational experience that could transfer to production rails once regulation catches up — and it has done so alongside the Japanese group best positioned to anchor the other end of the corridor.
Both companies said they plan further work linking digital asset exchange, settlement and asset management between the two markets.

yen straight to won skipping the dollar leg is the whole product. desks pay two spreads today for the privilege, this is an fx cost story before its a blockchain story
july through september with SBI Digital Practice on canton test env. zero real money moved, sure, but the direct yen-won pair skipping usd is the part fx desks will actually steal
yen stablecoin straight to won stablecoin without the dollar detour is quietly huge for settlement costs. every hop today is a fee and a delay
^ this. the two-step usd conversion is where the real friction lives, not the blockchain part
Kyobo and SBI actually tested inbound digital asset handling with procedures for settlement inside Korea. Not just another press release pdf pilot.
canton network again. the permissioned chain nobody can verify quietly winning all the institutional pilots smh
a korean insurer and a japanese securities group would never get signoff on a public chain for this. permissioned rails are the only reason this pilot exists at all
nobody can verify is exactly why kyobo legal signed off. an insurer is never putting claims flow on a chain where anyone can watch the balances, hate the design all you want
thats the point tho. no insurer wants counterparties reading their settlement flows on a public chain. permissioned is the feature here not the bug
every cross border desk in seoul is watching this. the usd detour adds a full business day to yen to won flows, cut that to hours and the treasury case writes itself
cutting a full business day out of yen-won flows is a treasury story before it is a crypto story. insurers move enough volume that hours saved compound fast
Cutting the dollar leg out of yen to won settlement is the entire story. Every hop through USD adds fees, time and counterparty exposure, and institutional treasury desks feel that daily.
and the delay per hop is worse than the fees. tokyo to seoul settlement takes days through correspondent banks, insurers feel that on every claim payout
Worth remembering this was test tokens on a Canton test environment, not live stablecoins. Technically promising, but zero real money moved so the operational kinks remain unknown.
fair on the test tokens, but they ran the full inbound handling and settlement sequence inside Korea. most of these pilots stop at the press release stage
test tokens sure, but the FX and settlement procedures ran against real counterparties on both sides. the unknown kinks are operational and those show up in exactly this kind of dry run
fair on the test tokens point but two months of running since july is still more than a weekend hackathon. kinks at least got poked at
An insurer running what it calls the first institutional stablecoin test in Korea is the notable part. These pilots usually come from banks. Kyobo doing it says something about where settlement demand actually is.
Kyobo being an insurer and not a bank is the detail everyone skips. cross border claims settlement is where the multi day delays actually hurt people
claims settlement is the sleeper use case. a won payout to a beneficiary in osaka today is a two bank hop with a USD leg in the middle. if the pilot result holds that turns into hours
claims settlement is the right wedge. a beneficiary in osaka waiting on a two bank hop with a usd leg in the middle is exactly the friction this should kill
