This report analyzes the impact of the Takaichi administration's reflationary policy stance on Japan's interest rate environment. Mizuho expects short-term bear-steepening of the JGB curve but maintains a baseline scenario of limited long-term rate increases.

Key Takeaways

  • 1.Market participants are increasingly focused on potential reflationary economic policies under the Takaichi administration, including expansionary fiscal policy and potential government pressure to keep monetary policy dovish.
  • 2.Baseline expectations do not project a sustained, long-term rise in interest rates above current levels, despite short-term volatility and testing of the upside.
  • 3.The JGB curve has shown bear-steepening tendencies, influenced by weak 10y JGB auction results and ongoing market sensitivity to potential policy shifts.
