Mitsubishi UFJ plans to launch "real-time settlement" for Japanese government bond transactions as early as fiscal year 2027. What’s noteworthy is not blockchain technology itself. By leveraging tokenized deposits and stablecoins, the time required for settlement can be significantly reduced, and the idle capital that financial institutions must hold can be minimized. In other words, this is about enhancing capital efficiency through digital assets. I advocate for “Digital Capital Management”—the strategic use of AI, data, digital assets, and stablecoins as new forms of corporate capital. Use AI to improve operational efficiency. Use data to elevate decision-making. Use digital assets to transform finance. Use stablecoins to revolutionize fund movements. Digital Capital Management is not merely digital transformation (DX). It is the digital redesign of “how a company’s money flows,” aimed at increasing capital efficiency and corporate value. This initiative by MUFG demonstrates that this trend has now reached the core of Japan’s financial system.
