MUMSS expects JGBs to trade rangebound with an upward bias during the week of August 17, 2026, aided by moderating US inflation and stabilizing UST yields. The BoJ is anticipated to raise policy rates in September 2026, reaching a terminal rate of 1.75% by June 2027.
Key Takeaways
- 1.JGBs are projected to trade rangebound with an upward bias for the week of August 17, supported by easing US inflation and fading expectations of an early Fed rate hike.
- 2.Market pricing reflects an ~80% probability of a BoJ rate hike in September 2026; MUMSS forecasts rate hikes to 1.25% in September 2026, 1.50% in January 2027, and a terminal rate of 1.75% in June 2027.
- 3.Fiscal policy and political changes pose key risks; speculation around FY27 budget requests, consumption tax cut funding, and a potential replacement of Finance Minister Satsuki Katayama could pressure the yen and steepen the JGB curve.
