[MARKET UPDATE] Further JPY strength seen in the minutes after Mimura's commentary 156.70 the current base.

Mimura occupies the currency diplomacy post at the Ministry of Finance, the chair from which verbal intervention against yen weakness has historically been run, and the market's reflex to comments from that office is well established: the yen firms in the minutes after remarks, with the size of the move scaling to how far rhetoric escalates relative to the last statement. The established escalation ladder runs from expressions of concern through warnings against excessive moves to language about readiness to act, and each rung up has historically bought less yen strength per comment as jawboning without follow-through loses credibility. The key distinction is between verbal intervention, which this is, and actual spot operations, which the ministry has on past occasions conducted after a period of intensified commentary and thin, one-sided positioning. Whether the strength holds typically depends on the broader rate differential backdrop, since past episodes show rhetoric slowing depreciation rather than reversing a trend driven by yield gaps. Tells for escalation are follow-up comments from the finance minister, any reference to being in contact with overseas counterparts, and the speed rather than the level of moves in the pair.
