Japanese officials have largely stopped issuing explicit verbal warnings on the yen, signaling a possible shift in how Tokyo handles potential FX intervention.
The quieter stance comes with the yen trading near its weakest level against the dollar in about 40 years, leaving traders with less guidance and more uncertainty over when authorities might act.
Economist Norihiro Yamaguchi of Oxford Economics said the lack of information itself may be part of the strategy, putting markets on the back foot rather than telegraphing intervention risk.
The change marks a contrast with Japan's earlier approach, when officials more clearly threatened action to support the currency.
