BlackRock Signs With SBI and Startale to Link Funds to JPYSC

SBI Holdings, Startale Group and two BlackRock entities signed a memorandum of understanding on Monday to study whether tokenized money market funds can be settled against JPYSC, the yen stablecoin SBI launched in June. BlackRock Financial Management and BlackRock Japan are both party to it. The work is split three ways: technology and infrastructure, business and distribution, and regulation and market development. Nothing in it commits anyone to a product, and no launch date appears in any of the three accounts read here. The memorandum's own text was not read at source.

Why the trust bank matters

JPYSC is issued through SBI Shinsei Trust Bank and distributed by SBI VC Trade, the group's licensed exchange. Japan amended its Payment Services Act in 2022 to make room for stablecoins, with the rules in force a year later, and fiat-backed tokens are classed as Electronic Payment Instruments that only licensed banks, trust companies and registered money transfer firms may issue. The Block is the one account read here that sets out that background. Bitcoin.com adds that the trust-type structure JPYSC uses escapes a 1 million yen cap on balances and transfers that applies to fund-transfer-type tokens such as JPYC. No other account carries the point, so it stands unconfirmed.

The fund half of the pairing has no name

Neither company said which funds would be linked. The Block names BUIDL, BlackRock's tokenized Treasury fund, as an example and is explicit that the memorandum identifies none. BUIDL launched in 2024 and holds about $2.17 billion in US Treasurys, overnight repurchase agreements and cash. Bitcoin.com carries the same figure, so it survives a cross-check; CoinGape does not mention the fund at all. The gap is wider on the stablecoin side. Four months after JPYSC went live, no account read here gives a circulating supply for it, and none of the three asked.

"The shift to onchain finance is becoming an unavoidable global trend," Yoshitaka Kitao, chairman and president of SBI Holdings, said.

All three accounts carry that sentence in the same words. The second quote in circulation is thinner. CoinGape attributes to Yukiko Hashimoto, president of BlackRock Japan, a line about advances in digital assets opening new possibilities for financial markets, then follows it with "he added" a sentence later. No other outlet carries the quote. Jonathan Steel, a managing director at BlackRock Financial Management, is paraphrased in that same piece on connecting traditional finance with digital-asset ecosystems and quoted nowhere.

What SBI has been assembling

Distribution has been the group's project for months. In August it bought about 20% of Indonesia's Ajaib with the yen token named as part of the reasoning, and CoinGape says SBI and Startale have joined the Open USD alliance to look at interoperability between JPYSC and OUSD. That last detail is one outlet's, like several here. What Monday adds is an asset manager on the other side of the trade, and a reason for a yen token to hold something other than payments.

The memorandum is open to other institutions in Japan and abroad, and that is the clause that would decide whether any of it travels. For now there is no fund, no settlement path and no date. What exists is three study areas and four signatures.
