Japanese bond investors are primed to react to any changes at the Government Pension Investment Fund (GPIF), as Japan shifts to expansionary fiscal policy, according to a wire report.

The GPIF is one of the world's largest pension funds and a significant holder of Japanese government bonds (JGBs). Any adjustment to its portfolio allocation under the new fiscal stance could influence JGB yields and the broader Japanese equity market (N225). The report highlights investor sensitivity to shifts in domestic fiscal and monetary policy coordination.
