SBI VC Trade said on the 7th that part of the reserve assets backing the yen-pegged stablecoin JPYSC is now being managed in short-term Japanese government bonds, in a move tied to Japan’s June easing of rules on eligible stablecoin reserve assets.

SBI Shinsei Trust Bank and SBI VC Trade are managing part of JPYSC’s reserve assets in Japanese short-term government bonds. SBI VC Trade said the initial amount moved into those instruments is 1 billion yen, or about $9.4 million.

JPYSC is structured as a yen-pegged stablecoin designed to maintain a 1:1 value with the Japanese yen. According to the announcement, SBI Shinsei Trust Bank is responsible for issuance and management, while SBI VC Trade handles issuance and distribution.

The reserve shift follows a June regulatory change in Japan. Under the revised Payment Services Act, trust-type stablecoins can, if certain conditions are met, manage up to 50% of their issuance amount in government bonds or time deposits with maturities of three months or less. Before that change, funds corresponding to the issuance amount of trust-type stablecoins had to be held in demand deposits.

SBI said the approach is intended to connect digital finance with traditional financial markets by using high-credit yen assets, including Japanese government bonds. The announcement did not disclose further operational details such as the broader size of JPYSC issuance, the pace of additional reserve reallocation, or whether the full 50% allowance will be used.

Why It Matters

This is an early example of how Japan’s stablecoin rules are being applied in practice rather than remaining a policy change on paper. Reserve composition is central to how regulated stablecoins manage safety, liquidity, and redemption design, so a shift from pure demand deposits to short-dated sovereign assets could influence how future yen-backed products are structured.

The move also highlights Japan’s effort to integrate stablecoins more closely with established financial infrastructure. If that model expands, it could strengthen the case for regulated local-currency stablecoins as payment and settlement tools within a framework that remains tied to traditional banking and high-quality reserve assets.
