SBI Holdings, Inc and Startale Group Pte. Ltd today announced they have joined Open Standard, the fast-growing alliance of more than 140 leading global companies, including Visa, Stripe, Mastercard, BlackRock, and Coinbase, driving the adoption of Open USD (OUSD), a U.S. dollar-denominated stablecoin built for global-scale settlement.

As part of this move, the two companies will explore interoperability between OUSD and JPYSC, the yen-denominated trust-type stablecoin issued by SBI Shinsei Trust Bank. The public launch of OUSD onchain provides a foundation for this partnership, with the companies working toward faster, more efficient settlement between the world’s two most-traded currencies.

The move comes as the global financial system undergoes a historic shift toward blockchain-based settlement. Landmark U.S. legislation, namely the GENIUS Act, has accelerated the build-out of regulated, enterprise-grade stablecoin infrastructure worldwide. In June 2026, this momentum culminated in the launch of Open Standard, uniting more than 140 companies spanning finance, payments, and technology behind a single mission: establishing OUSD as a common settlement layer for the onchain economy.

SBI and Startale have been at the forefront of this transformation in Asia. In July 2026, SBI Global Asset Management, DigiFT Tech Pte. Ltd., and Startale unveiled a proof-of-concept for settlement and distribution payments on tokenized securities, a project designed with JPYSC’s future utility in mind. Startale has continued to broaden JPYSC’s real-world use and to build institutional-grade trading infrastructure, extending onchain finance well beyond payments.

Against this backdrop, SBI and Startale see growing interoperability between JPYSC and OUSD as a powerful lever, one capable of streamlining yen-dollar settlement and unlocking new use cases for stablecoins across the onchain financial landscape. With OUSD now publicly launched, the companies will explore concrete opportunities to advance this vision.

Yoshitaka Kitao, Representative Director, Chairman, President & CEO, SBI Holdings, Inc, commented:

“As onchain finance continues to evolve, cross-border transactions will become increasingly prevalent. SBI Group is working to establish the ‘SBI APAC Digital Economic Zone,’ and believes that enabling seamless transactions across borders and currencies lies at the heart of this vision.

In particular, ensuring seamless convertibility between yen-denominated and U.S. dollar-denominated stablecoins is essential. Our participation in Open Standard and exploration of a proof of concept for interoperability between OUSD and JPYSC represent an important step toward achieving this goal. SBI Group has already become the first in Japan to offer the U.S. dollar-denominated stablecoins USDC and RLUSD, and will continue to promote the broader adoption of digital assets through collaboration with leading partners in Japan and overseas.”

Sota Watanabe, CEO, Startale Group Pte. Ltd, added:

“Our participation in Open Standard reflects the shared conviction of SBI and Startale that the future of finance is onchain, borderless, and interoperable by design. We see the opportunity to pilot interoperability between JPYSC and OUSD as highly significant. The yen and the dollar are two of the world’s strongest and most trusted currencies and enabling them to be exchanged and utilized seamlessly onchain could unlock significant opportunities. By working closely with the SBI Group and Open Standard’s partner companies, we aim to connect Japanese assets and financial services with global onchain markets through the creation of concrete use cases and help build that future.”

By joining Open Standard, SBI and Startale are positioning JPYSC for deeper integration with global stablecoin infrastructure, a move aimed at strengthening the international liquidity of yen-denominated assets. The companies will continue to deepen collaboration with Open Standard’s global partner network, working within applicable regulatory frameworks to build a safe, trusted, and truly interoperable stablecoin ecosystem for the onchain era.
