Tokyo, 29 July 2026 – Falling approval ratings for Prime Minister Sanae Takaichi’s cabinet are adding a political risk premium to Japan’s bond debate, as traders assess whether weaker public support could encourage fiscal measures that complicate the interest-rate outlook. The concern is how a pressured government may use tax cuts or other support to rebuild momentum.

Japan’s bond market is sensitive to policies that expand borrowing needs while inflation remains a concern. Expectations of fiscal support can lift longer-dated yields if investors anticipate heavier issuance or slower budget consolidation. Political uncertainty may also make monetary-policy communication harder because the central bank must separate economic conditions from shifting expectations around government spending.
