Japan's Finance Minister Satsuki Katayama Announces Largest Budget Reform Since WWII
Japan's Finance Minister Satsuki Katayama stated that Japan is undergoing the largest budget system reform since the end of World War II, aimed at reducing reliance on supplementary budgets and incorporating more unexpected expenditures into the initial budget.
The reform is set against the backdrop of a recently approved ¥3.1 trillion supplementary budget (including a ¥2.5 trillion reserve fund to address inflation from the Middle East conflict), with the current fiscal year's general accounting budget size at approximately ¥122 trillion. This move enhances expenditure predictability and supports planning for the private sector and local governments.
From a market mechanism perspective, the reform signals guide bond investors and institutional funds to reprice the risk of Japanese government bonds, reducing the pressure of additional bond issuance that raises yields. Beneficiaries include businesses and households that rely on a stable fiscal environment, while those under pressure are short-term speculative funds that depend on temporary stimulus.

Satsuki Katayama, as Japan's first female finance minister, has been promoting fiscal policy adjustments since taking office in October 2025. This reform continues her emphasis on "responsible proactive fiscal policy" under the Takaichi cabinet, having participated in expenditure control and supplementary budget management amid high debt-to-GDP ratios.
In terms of capital pathways, the Japanese government aims to mobilize public funds and private capital resources through budget system optimization, bringing unexpected expenditures from supplementary budgets into the initial budget. This move seeks to reduce market uncertainty regarding additional bond issuance, providing a more stable financing environment for long-term debt management and economic growth, while supporting a wage-price positive cycle strategy.
Similar to the expansionary budget promoted by Ikeda Hayato in the 1960s through the income doubling plan, Japan is currently in a controlled phase of transitioning from a post-war high-frequency supplementary budget model to a standardized initial budget, aiming to rebuild fiscal discipline and strengthen its policy autonomy among globally high-debt economies.
Essentially, this represents a regulatory change and capital concentration: budget reform compresses the flexibility of temporary expenditures through mechanism adjustments, forcing fiscal resources to concentrate on more predictable priority areas, accelerating the shift of public capital from reactive responses to strategic allocation, and reshaping the power structure between government and market in long-term investment pricing.
