JPYSC Passes 30B Yen as SBI Wires a Stablecoin Balance Sheet in One Week

Japan’s RWA push is moving from “tokenizing assets” to “circulating capital”: a stablecoin cash leg, yield assets, credit assets, and cross-border settlement rails all connected by SBI within a single week.

On November 2, SBI VC Trade announced that the handled balance of its yen stablecoin JPYSC had surpassed 30 billion yen, with the lending balance alone exceeding 10 billion yen. What makes the number notable is the timing: roughly five months after launch, SBI signed four deals in the same week with BlackRock, CRB Group, SMBC, and Erebor Bank. The yen stablecoin race is shifting from “who can issue” to “who can make the coin circulate on a balance sheet.”

1. Beyond 30B Yen: A Trust-Type Stablecoin Enters Real Capital Use

JPYSC uses a trust structure: SBI Shinsei Trust Bank is the issuer managing the trust property, SBI VC Trade handles distribution, and Startale provides the technical infrastructure. Reserve assets have begun to include Japanese government bonds, connecting off-chain reserves directly to the traditional yen money market. The lending product launched in July offers three tranches, 2% annualized at 28 days, 2.5% at 84 days, and 3% at 168 days, with applications accepted every Thursday. With 10 billion of the 30 billion yen held as loans, the stablecoin has begun to take on a deposit-like cash management function.

SBI made clear in the announcement that JPYSC still needs legal amendments before it can be “publicized,” meaning free circulation on a public blockchain. For now, the more accurate positioning is a digital yen infrastructure expanding inside the regulated financial system, not a stablecoin already open to DeFi markets. Unlike the global path of “open first, regulate later,” Japan is choosing to build the rails first and release the water later.

2. Four Deals in One Week: From Yield Assets to Credit Assets to Cross-Border Rails

On October 27, SBI, Startale, and BlackRock signed a basic cooperation agreement to study connecting a tokenized money-market fund to JPYSC, covering technical infrastructure, business distribution, and regulatory market building. On October 28, SBI formed a strategic partnership with CRB Group, the parent of US lender Cross River Bank, to set up a joint venture in Japan developing RWA products such as loan receivables, and to study JPYSC as a settlement tool for tokenized-asset and cross-border transactions. On October 30, SBI and the SMBC Group reached a capital and business alliance, with SMBC taking a 5% stake in SBI Startale Marketing so its 24 million retail customers can use JPYSC. On November 2, SBI announced a $100 million investment in Erebor Bank through its US subsidiary.

The four deals stitch together a complete on-chain balance sheet: JPYSC is the cash and settlement layer, the tokenized MMF is the low-risk yield asset, loan receivables and private credit are the credit assets, and Erebor Bank and Cross River are the cross-border settlement rails and distribution entry points. Erebor, co-founded with Anduril co-founder Palmer Luckey, holds an OCC national bank charter and FDIC insurance, opened in February 2026, passed $7 billion in deposits by September, and runs its own blockchain-based core system supporting 24/7 settlement and stablecoin deposits and withdrawals. Robinhood Ventures had already invested $30 million in preferred stock in October.

3. Contrast with JPYC: The License Pioneer Loses on Distribution

The same week, JPYC, the first licensed yen stablecoin, admitted it had “not grown in its first year”: one year after launch, circulation is around 3 billion yen, a quarter of its internal target, with the 1 million yen per-transaction cap cited as a key constraint. The contrast is sharp: JPYC got the license earlier, but SBI is winning through deep binding with bank channels and asset management channels. Distribution decides outcomes; issuance capability itself has been commoditized.

JPYC is not without progress. After Japan’s duty-free system switched to “pay first, refund later” on November 1, Japan Tax Free and UPBOND began paying consumption-tax refunds to tourists in JPYC on the Avalanche C-Chain, the first government public-payment use case for a yen stablecoin. UPBOND also plans to add refund functionality to its Agentic Wallet. But overall, the yen stablecoin scaling narrative has been taken by SBI.

4. Global Mix: The Fed’s Regulatory Gap

On November 5, Cleveland Fed President Beth Hammack said at the SNB conference that AI agents using stablecoins would be a major shift in how money moves, and that smart contracts and agentic workflows could significantly increase stablecoin demand, and with it demand for dollar assets. But current US rules do not comprehensively cover smart contracts or agentic AI payments; the GENIUS Act rules take effect by January 2027 at the latest, still leaving responsibility, compliance, and oversight gaps. While the US debates rules, Japan has already built the rails directly on licensed institutions’ balance sheets.

5. Conclusion

JPYSC passing 30 billion yen and SBI’s four deals in one week mark Japan’s stablecoin push moving from “issuance narrative” to “balance-sheet access.” When a stablecoin can buy tokenized funds, tokenized funds manage cash, loan receivables enter on-chain asset pools, and banks provide custody, distribution, and cross-border settlement, RWA becomes genuinely new financial infrastructure. For practitioners, the real watershed is not issuing more tokens but forming a stable loop among yen cash, yield assets, credit assets, and cross-border settlement.
