Revolutionary Step by the Bank of Japan: 24/7 Blockchain-Based Payment Trial Begins

A historic turning point is unfolding in Japan's financial system. The Bank of Japan (BOJ), in an announcement by Governor Kazuo Ueda on March 3, 2026, has decided to test the instantaneous, 24/7 settlement of current account deposits (reserves) held by banks at the central bank using blockchain technology. This initiative is a key part of a "sandbox" project that pushes the boundaries of traditional financial infrastructure and has the potential to shape the payment systems of the future.

In today's financial system, interbank transfers and securities settlements are generally limited to working hours and holidays. This can lead to liquidity shortages and the risk of "gridlock," especially during periods of economic stress. The trial launched by the BOJ aims to solve precisely these problems: thanks to tokenized reserves on the blockchain, transactions can now be completed almost instantly, day and night, weekends and holidays included. This will fundamentally improve liquidity management for financial institutions and significantly reduce systemic risks.

The project is progressing within the framework of the BOJ's existing "sandbox" studies. Tests, starting with prototype development in the second quarter of 2026, will continue with real-world trials with selected financial institutions throughout 2027. The results are expected to be publicly released in early 2028. During the trials, critical elements such as how the blockchain infrastructure can be integrated with the existing BOJ-NET system, security level, transaction speed, and cost-effectiveness will be rigorously examined.

In his speech, Governor Ueda emphasized that blockchain technology is not only a tool for innovation but can also become the fundamental infrastructure of a next-generation financial ecosystem while maintaining the "anchor of trust" role of central bank money. The project focuses specifically on use cases such as domestic interbank payments and securities settlements (DVP - delivery versus payment). Studies, conducted with the participation of external experts, will test the practical applicability of the technology and its compatibility with existing systems.

This step makes Japan the first G7 country to test central bank reserves on blockchain technology. It also strongly demonstrates Japan's ambitious position in the digital transformation race among the world's leading central banks.

The BOJ's bold experiment could be a catalyst not only for the Japanese financial system but also for the global monetary and payment ecosystem. Opening the doors to a 24/7 instant settlement era, this project is poised to go down in history as one of the most concrete examples of bridging the gap between traditional finance and the blockchain world.

The financial architecture of the future is taking shape in Japan today.
