Japan Faces Market Volatility Over Proposed ¥370 Trillion Fiscal Expansion

The Japanese government has proposed a ¥370 trillion investment plan targeting 17 industrial sectors through 2040. The initiative aims to double economic growth to over 1% while reducing trade reliance on China and advancing AI capabilities. However, the lack of a clear funding mechanism has triggered significant investor concern regarding long-term fiscal sustainability.

Financial markets have responded negatively, with the yen depreciating to 163 against the US dollar, a four-decade low. Yields on Japanese government bonds have climbed to 2.8%, marking a 29-year high. These movements reflect broader market anxiety over the potential for an unfunded fiscal shock similar to previous international precedents.

Inflationary pressures remain a primary risk, as the weakened yen increases the cost of energy and raw material imports. While core inflation has hovered near the Bank of Japan’s 2% target, recent geopolitical instability has pushed quarterly figures into the mid-2% range. The government’s proposed policy framework has also raised concerns regarding the preservation of central bank independence, despite cabinet-level assurances to the contrary.
