BlackRock, SBI and Startale Explore JPYSC Tokenized Fund Link

BlackRock has signed a memorandum of understanding with SBI Holdings and Startale Group to explore connecting tokenized money market funds with JPYSC, a yen-denominated trust-type stablecoin issued by SBI Shinsei Trust Bank. According to the official Startale announcement published October 27, the agreement covers technology and infrastructure, business and distribution, and regulatory and market-development work. The collaboration involves BlackRock Financial Management and BlackRock Japan, alongside SBI Holdings and Startale.

The agreement is exploratory rather than a production deployment. The companies have not identified a specific BlackRock fund that would be connected to JPYSC, disclosed a technical architecture, or announced a commercial launch date. That distinction matters because BlackRock already operates several tokenized cash-management products, while the MOU refers only to tokenized MMFs as a category. The partnership therefore establishes a framework for evaluating connectivity, not a live bridge between JPYSC and BUIDL or another named fund.

Japan Builds Yen Settlement Infrastructure

Japan’s stablecoin framework gives the project a defined regulatory perimeter. JPYSC launched on June 24 as a trust-type electronic payment instrument, with SBI Shinsei Trust Bank as issuer and SBI VC Trade handling distribution. Its initial rollout was limited to SBI VC Trade accounts, while the group said broader public-chain circulation would follow as legal and tax arrangements were addressed. By September, part of JPYSC’s backing assets had begun to include short-term Japanese government bonds.

The proposed connection would extend a broader institutional trend in which tokenized fund shares are being integrated with digital-asset settlement and collateral systems. BlackRock has already expanded beyond BUIDL with tokenized money market products designed for institutional cash management and stablecoin reserves, while eligible OKX clients can use BUIDL as off-exchange trading collateral. Tokenized RWA active AUM surpassed $31 billion in October, illustrating the growing financial infrastructure surrounding blockchain-based securities.

Under the MOU, the parties will examine how tokenized MMFs and JPYSC could interact across infrastructure, distribution and regulation. The stated objective is to develop compatible on-chain workflows for regulated fund products and yen-denominated digital settlement. However, the announcement does not establish that fund subscriptions, redemptions or secondary transfers will settle directly in JPYSC, nor does it specify which blockchain networks would support any eventual integration.

Tokenized Funds Move Toward Financial Utility

The initiative builds on SBI and Startale’s existing work around JPYSC. Earlier in October, the companies joined Open Standard and said they would explore interoperability between JPYSC and the dollar-denominated Open USD stablecoin. Startale has also announced a digital corporate bond whose interest and principal are scheduled to be paid in JPYSC. Those initiatives are expanding the potential roles of JPYSC across payments, settlement and regulated financial products, although each remains subject to its own operational structure and implementation timeline.

For BlackRock, the Japanese MOU broadens the geographic scope of its tokenization work without yet creating a new investable product. Tokenized funds are increasingly being designed for uses beyond passive holding, including collateral, liquidity management and blockchain settlement. The CFTC has separately clarified how qualifying tokenized money-market fund shares can fit within existing collateral rules for regulated derivatives firms. The underlying legal wrapper therefore remains important even when fund ownership and transfer infrastructure moves on-chain.

The immediate milestone is the feasibility agreement itself: BlackRock, SBI and Startale will jointly assess whether tokenized MMFs can be connected to JPYSC within Japan’s regulatory framework. Any practical impact will depend on the specific fund structure, settlement design, eligible users and regulatory requirements that emerge from that work. Until those details are disclosed, the MOU represents an institutional effort to build yen-based on-chain financial infrastructure rather than evidence of an already functioning tokenized-fund settlement market.
