BlackRock, SBI and Startale explore JPYSC fund connection

BlackRock Financial Management and BlackRock Japan signed a memorandum of understanding with SBI Holdings and Startale Group to explore connecting tokenized money market funds with JPYSC, according to the companies.

The review covers three areas: technology and infrastructure, business and distribution, and regulation and market development. The parties will examine the technical requirements for an integration, consider distribution models that use their respective networks and market access, and assess relevant regulatory developments.

That is the verified extent of the plan. The announcement describes an exploration, not a live connection. It sets no launch date or final product terms. It also establishes no immediate route for investors to access JPYSC through a BlackRock fund.

BlackRock launched its tokenized fund BUIDL in 2024. The release said it has grown into one of the largest of its kind, with around $2.17 billion in U.S. Treasurys, overnight repos and cash under management. That record shows the scale of BlackRock’s tokenized-fund activity. It does not establish that BUIDL will connect with JPYSC because the MOU names no target fund.

Yoshitaka Kitao, SBI Holdings’ representative director, chairman and president, tied the project to Japan’s position in global finance. “The shift to onchain finance is becoming an unavoidable global trend. If Japan is to lead this transformation rather than fall behind, we must prepare early and build the foundations for the next generation of financial markets,” he said.

What could the JPYSC connection change?

For tokenized fund providers, the practical question is how a yen stablecoin could connect with a tokenized portfolio. The MOU does not answer that. It starts with infrastructure, then tests whether the parties can turn the link into a repeatable distribution model.

The three parties will explore the technical requirements and infrastructure needed to support the integration. They will also examine potential business models and distribution opportunities by leveraging their respective networks and market access. The collaboration is designed to remain open to other financial institutions and businesses in Japan and internationally.

SBI and Startale launched JPYSC in June, according to the announcement, as Japan’s first trust bank-backed yen stablecoin. SBI Shinsei Trust Bank manages its issuance. SBI VC Trade, a licensed crypto exchange, handles its distribution. That division gives the proposal a defined stablecoin operating chain. The unresolved part is how tokenized funds enter it.

Japan’s stablecoin rules add another layer. The country amended the Payment Services Act in 2022, and the framework came into force a year later. The rules classify fiat-backed stablecoins as Electronic Payment Instruments and limit their issuance to licensed banks, trust companies and registered money transfer services.

Regulatory review is therefore part of the work, not a closing formality. The parties will consider relevant regulatory developments when assessing the market environment for tokenized assets and stablecoins. The companies said: “The next step is to develop the infrastructure, distribution channels, and regulatory frameworks needed to connect tokenized assets with stablecoins and support broader market adoption.”

The announcement gives no public deadline. If the project advances, the first visible change will be a disclosed technical design, distribution arrangement and regulatory path; until then, JPYSC remains a proposed link rather than an operating feature of BlackRock’s tokenized funds.
