BlackRock, SBI and Startale Explore Linking Tokenized Funds With Yen Stablecoin

BlackRock is exploring a new way to connect traditional financial products with blockchain-based payments in Japan. The asset manager has signed a memorandum of understanding (MOU) with Japanese financial group SBI Holdings and blockchain infrastructure firm Startale Group to study linking tokenized money market funds with JPYSC, a yen-denominated stablecoin.

The agreement brings together BlackRock Financial Management, BlackRock Japan, SBI Holdings, and Startale. The companies will examine the technology, commercial opportunities, distribution channels, and regulatory requirements needed to connect tokenized money market funds with JPYSC.

The announcement, made on October 27, does not confirm a live integration, a specific fund for the project, or a commercial launch date. Instead, it establishes a framework for the companies to explore how tokenized investments and digital payments could work together.

How tokenized funds could work with JPYSC

Money market funds invest in short-term financial instruments, such as government securities and repurchase agreements. They are commonly used by investors and institutions to manage cash while earning a return.

Tokenization represents fund shares as digital tokens on a blockchain. Depending on the product's structure and rules, these tokens can support digital transfers and settlement while representing an investment in the underlying fund.

JPYSC, meanwhile, is a yen-denominated stablecoin developed by SBI Holdings and Startale. It is designed to maintain a value linked to the Japanese yen and provides a digital payment instrument for blockchain-based transactions.

Connecting the two could allow eligible users to move between tokenized fund investments and yen-denominated digital money through compatible infrastructure. In a potential model, JPYSC could serve as the payment leg when investors subscribe to or redeem tokenized fund shares, subject to the fund's terms and applicable regulations.

However, this remains a proposed use case. The companies have not announced how transactions would work, which fund would participate, or whether the integration would support subscriptions, redemptions, secondary-market transfers, or all three.

BlackRock expands its tokenization strategy

The MOU fits into BlackRock's broader effort to bring traditional financial products onto blockchain networks.

The asset manager launched its USD Institutional Digital Liquidity Fund, known as BUIDL, in 2024. The fund provides eligible investors with tokenized exposure to a portfolio built around cash, U.S. Treasury securities, and repurchase agreements.

BlackRock has continued expanding its tokenized money market offerings. In August 2026, it announced two additional products designed for institutional investors and digital-asset markets, including a vehicle intended to support stablecoin reserve management.

Altcoin Buzz previously covered BlackRock's launch of tokenized money market funds on Solana and Ethereum. That development shows how the company is extending traditional cash-management products into blockchain-based environments.

The Japanese initiative would explore a different connection: pairing tokenized investment products with a yen-based stablecoin rather than focusing only on the issuance of tokenized fund shares.

The latest announcement does not explicitly identify BUIDL or either of BlackRock's newer funds as the product that will be connected to JPYSC. Any specific fund integration would need to be confirmed by the participating companies.

SBI and Startale push Japan's onchain finance infrastructure

SBI Holdings brings established financial services operations to the partnership, including banking, securities, asset management, and digital-asset businesses. Startale contributes blockchain infrastructure and application development.

The two companies launched JPYSC in June 2026. SBI Shinsei Trust Bank handles issuance, while SBI VC Trade manages distribution.

Their work on the stablecoin is part of a broader effort to develop infrastructure for digital payments and tokenized financial products. SBI and Startale have also explored interoperability between JPYSC and Open USD, a dollar-denominated stablecoin, as they work toward connecting different digital payment systems.

The new BlackRock agreement expands that effort into tokenized money market funds. It also brings a major global asset manager into discussions about how traditional investment products could operate alongside yen-denominated digital money.

SBI Holdings Chairman and President Yoshitaka Kitao said the shift toward onchain finance was becoming an unavoidable global trend. He said the partnership would help build infrastructure for the next generation of financial markets in Japan and internationally.

Regulation remains a key part of the plan

Japan has established a legal framework for stablecoins through amendments to its Payment Services Act. That framework provides rules for qualifying digital payment instruments and the entities permitted to issue them.

Still, connecting a stablecoin with an investment fund involves more than making the two assets technically compatible. The companies must also examine how fund distribution, investor eligibility, settlement, custody, and other regulatory requirements would apply to the proposed arrangement.

The MOU identifies three areas for further work: technology and infrastructure, business and distribution, and regulation and market development.

The companies also intend to engage with other financial institutions and businesses in Japan and overseas. This leaves room for additional participants, although no further partners or commercial arrangements have been confirmed.

Regulatory review is particularly important because stablecoins and money market fund shares serve different purposes. JPYSC is designed to maintain a yen-linked value, while tokenized fund shares represent an investment whose value and returns depend on the underlying fund and its terms.

A successful connection would need to preserve those distinctions while allowing the assets to interact within the applicable rules.

What the partnership could mean for onchain finance

The proposed connection reflects a wider effort to make blockchain infrastructure useful for conventional financial activity. Tokenized funds can represent investment products digitally, while stablecoins can provide a means of transferring value onchain.

If the project advances, linking the two could make some financial transactions more compatible with digital settlement systems. It could also give institutions another way to explore how traditional cash-management products fit into blockchain-based markets.

But an MOU is an early step, not evidence that the intended benefits have already been achieved. The companies have not disclosed an investment commitment, expected transaction volume, or timeline for launching a combined service.

For now, BlackRock, SBI Holdings, and Startale are assessing whether the technical, commercial, and regulatory pieces can come together. The next meaningful milestones will be the selection of participating products, details of the proposed integration, and confirmation that the service is ready for market use.

The agreement puts Japan's yen stablecoin infrastructure and BlackRock's tokenization business into the same conversation. Whether that becomes a functioning financial product will depend on what the partners build next.
