SBI Maps Five-Layer Path to Zero-Cost Stablecoin Infrastructure

Japan’s SBI Group is pursuing a phased migration of traditional financial services onto blockchain rails, putting regulatory compliance ahead of product expansion. Its strategy treats stablecoins not merely as payment tokens but as foundational infrastructure that financial institutions could use routinely at near-zero cost. The approach reflects a broader industry effort to combine blockchain settlement and tokenized assets with the controls required in regulated markets.

SBI has now outlined a five-layer architecture spanning a Canton Network-based settlement layer, stablecoins, tokenized assets and higher-level market trading functions. The group said the layers would be introduced deliberately as regulation and supporting infrastructure mature. SBI did not disclose an investment amount or a firm launch date, but presented the sequencing as essential to moving conventional finance on-chain without deploying products before compliance and settlement foundations are ready.
