$7 Trillion Japan Bond Market is Moving to the Blockchain

Japan is preparing to overhaul its bond and stock settlement infrastructure by moving to blockchain technology. Regulators aim to enable near‑instant, round‑the‑clock settlement for Japanese government bonds (JGBs) and equities.

Timeline and Leadership

The initiative will begin this summer, led by the Financial Services Agency (FSA), the Ministry of Finance, and the Bank of Japan. A development plan is expected by early 2027, with a possible live system in the early 2030s.

Current Settlement Delays

Today, a stock trade in Tokyo settles in two days and a JGB trade in one day. The new blockchain rails aim to reduce this lag to near zero, allowing sellers to reinvest cash almost immediately.

Scale of the Market

Japan holds roughly 1,166 trillion yen in outstanding government bonds and bills, equivalent to about $7 trillion at current exchange rates.

Industry Participation

Four major Japanese banks are already testing blockchain collateral for JGBs, and firms such as Mizuho, Nomura, JSCC, Digital Asset, SBI, and the Solana Foundation are involved in related tokenisation and stablecoin projects.

Market Context

The move comes as Japan’s bond yields are near multi‑decade highs, with the 10‑year JGB yield around 2.9% and the 30‑year above 4%. Faster settlement does not address yield pressures but could improve capital efficiency by eliminating idle cash during settlement.

Next Steps

The plan still requires formal approval, and the final choice of blockchain platform will indicate the seriousness of the rollout.
