The confirmation closes off speculation that Japanese authorities had stepped into the market during a stretch of September, so any yen moves in that window were left to private flows rather than official action. That matters most for traders who read sharp currency swings as possible intervention and for policymakers weighing how much verbal signaling alone can accomplish. Whether the MOF's restraint holds if volatility returns is the open question.
