Core Viewpoint - The article discusses the economic stimulus plan introduced by Prime Minister Kishi Sanae, which is expected to weaken the yen and increase inflationary pressures in Japan. The combination of expansive fiscal policy and tight monetary policy may lead to risks of a reversal in carry trade, necessitating caution regarding the divergence in monetary policies between the Bank of Japan and the Federal Reserve [2][8]. Group 1: Economic Stimulus Plan - Kishi Sanae's economic stimulus plan amounts to 21.3 trillion yen (approximately 135 billion USD), slightly exceeding market expectations of 17 trillion yen. The fiscal deficit rate for Japan is projected to rise significantly in 2026 [3][9]. - The stimulus plan focuses on three main areas: 55% for inflation subsidies and social welfare (11.7 trillion yen), 34% for strategic industry investments (7.2 trillion yen), and 8% for defense and diplomacy (1.7 trillion yen) [3][15]. Group 2: Impact on GDP and Inflation - The expansive fiscal policy may raise Japan's GDP growth by 0.5 percentage points in 2026, which is lower than the contributions expected from the US (0.6 points) and Germany (0.63 points). The fiscal deficit rate is expected to increase by 1.77 percentage points in Japan, compared to 1.0 points in the US and 0.84 points in Germany [4][23]. - While the inflation subsidies may temporarily lower the overall CPI growth by 0.7 percentage points in early 2026, they could simultaneously increase core inflation pressures in the medium term due to rising real incomes and a weaker yen [4][29]. Group 3: Risks of Carry Trade Reversal - The combination of high inflation and a weak yen makes it difficult for Kishi's expansive fiscal policy to coexist with the Bank of Japan's loose monetary policy. Recent hawkish signals from the Bank of Japan suggest a potential shift towards interest rate hikes [5][35]. - The divergence between the yen and US dollar interest rates, with the yen reaching a low of 157.9 against the dollar while the US-Japan 2-year interest rate spread narrows to around 2.5%, indicates that the market has priced in risks associated with Japan's fiscal expansion [5][41]. - The current conditions suggest a potential for a reversal in carry trade, although the impact may be milder compared to August 2024. Factors such as net short positions in the yen, the degree of divergence between exchange rates and interest rates, volatility, and triggering conditions should be monitored [5][47].
