By late September 2026, the yen weakened toward the 159 level as widening interest rate differentials and rising U.S. rates persisted. Market dynamics have shifted from a primary focus on interest rate differentials to a complex interplay between monetary policy and fiscal stability.

Analysts warn that if interest rates rise due to fiscal deterioration rather than normalization, it could trigger a ‘triple sell-off’ of the yen, bonds, and stocks.
