SBI and Startale join Open Standard to explore interoperability between JPYSC and OUSD

On October 16, SBI Holdings and Startale Group announced their participation in Open Standard to explore the interoperability of the dollar-pegged stablecoin OUSD and the yen-denominated trust-based stablecoin JPYSC. The article states that Open Standard will launch in June 2026, and the alliance already includes over 140 global companies, including Visa, Stripe, Mastercard, BlackRock, and Coinbase, with OUSD already publicly launched on-chain. The announcement clarified that this only involves exploring a pilot project and does not represent the launch of new commercial services or the initiation of production environment settlements or trading activities.

Yoshitaka Kitao, Representative Director, Chairman, President, and CEO of SBI Holdings, stated that cross-border transactions will become more common, and seamless conversion between yen and dollar stablecoins is crucial. Joining Open Standard and exploring related proof of concepts is an important step. He also mentioned that the SBI Group has been the first in Japan to offer dollar stablecoins USDC and RLUSD. Startale Group CEO Sota Watanabe stated that joining Open Standard reflects both parties' belief that the future of finance is on-chain, borderless, and interoperable, and that the pilot interoperability of JPYSC and OUSD is of significant importance.

JPYSC is issued by SBI Shinsei Trust Bank and is positioned as an on-chain yen settlement infrastructure compliant with Japan's Payment Services Act and trust law framework. In July 2026, SBI Global Asset Management, DigiFT, and Startale announced a proof of concept for tokenized securities settlement and distribution payments, considering the future use of JPYSC. Open Standard claims it was established in 2026, with founding partners including Coinbase, Mastercard, Shopify, Stripe, and Visa, and over 200 institutions have signed up to add OUSD to the platform.
