BoJ is reportedly likely to keep rates unchanged in October, but could signal that a rate hike could come in December; the Bank may also raise its FY27 inflation forecast slightly, sources say.

Source-sourced previews of this kind are an established feature of BoJ communication, which has historically used press guidance to condition positioning ahead of live meetings and thereby blunt the surprise that has on past occasions triggered outsized moves in JGBs and the yen. The pattern to note is the sequencing: a hold paired with explicit forward signalling has tended to keep the front end bid while the yen's reaction hinges on whether the December signal is read as conditional or as a commitment, a distinction the Governor's press conference language on the output gap and wage momentum has typically settled. A modest upward revision to the outer-year inflation forecast is the more durable tell, as forecast changes of this kind have historically mattered more for the path than for any single meeting, and one that leaves the projection at or above target strengthens the case for normalisation continuing into the next fiscal year. The actors worth tracking are the board's known hawks, whose dissents have in past cycles prefigured the timing of subsequent moves, and the political backdrop, since government pressure has occasionally slowed but rarely reversed tightening sequences. Follow-ons are further source stories in the days ahead, the meeting statement, and the post-meeting briefing, where the precise wording on the December conditionality will determine whether the market treats this as a locked-in date or an open option. As a preview rather than a decision, the signal is directional and subject to revision.
