SBI Holdings Taps Solana to Build Japan’s Institutional On-Chain Finance Market

SBI Holdings has entered into a strategic partnership with the Solana Foundation to build an on-chain financial market for real-world assets, stablecoins and institutional settlement.

Under the agreement, the Solana Foundation will acquire an equity stake in SBI R3 Japan, joining existing shareholders SBI Holdings and Sumitomo Mitsui Financial Group, a G-SIB. Financial terms have not been disclosed.

The entity is expected to be renamed SBI Solana Global following standard corporate procedures.

From Pilots to On-Chain Market Infrastructure

SBI Solana Global will focus on four areas. The first is stablecoins, including support for issuing and distributing JPYSC and other yen-denominated tokens.

The second is real-world asset tokenisation. The partners plan to bring corporate bonds, commercial paper, real estate and investment funds onto Solana infrastructure.

The third is cross-border settlement. According to SBI, the platform is intended to connect Japanese financial assets with global liquidity pools.

The fourth is payments infrastructure for AI agents. No launch timeline has been disclosed.

Building on Japan’s Regulatory Framework

The partnership builds on Japan’s existing regulatory framework for stablecoins and security token offerings, one of the more established regimes among major financial markets.

SBI said the venture is intended to support Japan’s position as a regional hub for on-chain finance by expanding the market for Japan-originated digital assets.

The structure combines regulated Japanese financial assets—including stablecoins issued under Japan’s Payment Services Act and tokenised securities governed by existing disclosure rules—with Solana’s public blockchain infrastructure.

Open Questions

Several important details remain undisclosed. SBI has not revealed the size of Solana Foundation’s equity stake, launch timelines for individual products or revenue expectations for the venture.

The announcement also follows several recent digital asset initiatives by SBI, including the March launch of a regulated yen stablecoin with Startale, RLUSD distribution in Japan through Ripple and a non-binding letter of intent to acquire Bitbank.

Whether Bitbank, SBI VC Trade or another group entity will ultimately distribute products developed through SBI Solana Global has not been disclosed.
