Japan FX chief Mimura: No comment on current FX moves

Mimura's refusal to comment on current moves while flagging dissatisfaction signals a deliberate shift in verbal intervention strategy, likely aimed at keeping markets guessing rather than telegraphing specific action. This matters because it maintains maximum flexibility for actual intervention while avoiding the self-imposed pressure of explicit thresholds. The open question is whether this ambiguity will be enough to steady the yen, or if markets will test authorities with sharper moves before any concrete step emerges.
