Nomura Holdings Executive: Promoting Japanese Government Bonds into On-Chain Collateral System
Mizuho Financial Group, Nomura Holdings, Japan Securities Clearing Corporation, and Digital Asset have jointly launched a pilot project for the digital collateral management of Japanese Government Bonds (JGB), testing the transfer of rights and ledger updates within a multi-tiered account system based on the Canton Network under the current legal framework.
The focus of the experiment is to connect JGB to the on-chain system for 24-hour real-time collateral trading and cross-border mortgage scenarios without altering the legal attributes of JGB, while also assessing whether existing regulations need to be adjusted to accommodate the new clearing and custody model.
Digital Asset has previously advanced tokenized assets and institutional-level blockchain applications on the Canton Network with several international financial institutions. Related English research generally believes that high-credit assets like government bonds are the most likely financial products to achieve on-chain status first.

This experiment's key lies not in "blockchain applications," but in the "reconstruction of the collateral system." Government bonds are the core collateral assets in the global financial system, widely used for repos, derivatives margins, and inter-institutional liquidity management. If government bonds can achieve real-time transfer and settlement on-chain, it means that the speed of collateral circulation will be compressed from "T+1/T+0" to near real-time, directly enhancing capital efficiency.
Choosing to "not change legal attributes" is a core strategy. This means Japan is not trying to create new assets, but rather mapping existing safest assets onto a new technological track, thereby reducing institutional resistance. This approach aligns with the logic of the West promoting "tokenized government bonds": not to disrupt the system, but to upgrade the clearing layer.
The positioning of the Canton Network also indicates that this is not a public chain experiment, but a permissioned network aimed at institutions, emphasizing privacy, compliance, and multi-party collaboration. This reflects the current choices of mainstream financial institutions: to introduce blockchain efficiency in a controlled environment rather than directly migrating to a fully open system.
The deeper impact lies in global collateral competition. Whoever can make their national government bonds circulate more efficiently in the digital system can enhance their attractiveness as global collateral assets. Against the backdrop of the long-term dominance of U.S. Treasury bonds, Japan's attempts are essentially vying for a place in the future "on-chain liquidity" for yen assets.
