SBI Holdings, the Japanese financial services group, and Startale Group, a Singapore-registered Web3 infrastructure developer, have joined Open Standard, an alliance backing the U.S. dollar stablecoin Open USD (OUSD).

In a statement last Friday, SBI said the two companies will also explore collaborating the yen-denominated stablecoin JPYSC with OUSD. The pilot can help speed up yen-dollar settlement onchain.

Open Standard has more than 140 members, including Visa, Stripe, Mastercard, BlackRock, and Coinbase. Its goal is to make OUSD a common settlement layer for the onchain economy. The alliance started in June 2026 and launched OUSD on the Solana blockchain.

Open Standard said partners can issue and redeem OUSD without fees or transaction limits. Most reserve income after costs goes back to partners, it added.

JPYSC is a yen stablecoin issued by SBI Shinsei Trust Bank under Japan’s Payment Services Act and trust law. SBI and Startale launched it on June 24, 2026, for clients of the SBI VC Trade platform, with plans for wider use on public blockchains once legal, tax, and regulatory approvals are in place.

Yoshitaka Kitao, chairman, president and CEO of SBI Holdings, said cross-border transactions will become more common as finance moves onchain. SBI is working to build an “SBI APAC Digital Economic Zone” and seamless conversion between yen and dollar stablecoins is essential to that goal. He noted that SBI was the first in Japan to offer the dollar stablecoins USDC and RLUSD.

Sota Watanabe, CEO of Startale Group, said the companies see a pilot linking JPYSC and OUSD as highly significant. Cnnecting yen and dollar assets onchain can unlock new opportunities, the executive added.

The two companies said that in July 2026, SBI Global Asset Management, DigiFT Tech and Startale announced a proof of concept for settling and distributing tokenized securities, with potential future use of JPYSC.
