Japan's September PPI Rises 6.8% YoY, Easing Short-Term Rate Hike Pressure on BOJ
nashnova research
Japan's September PPI (producer price index) slowed to 6.8% year-on-year from 7.6% in August, the sharpest single-month drop since May, easing near-term rate-hike pressure — but swap markets still price in another hike by January at the latest.
How big was the PPI pullback?
September corporate goods prices rose 6.8% year-on-year, down sharply from August's 7.6%, with a 0.3% month-on-month decline.
This is the largest single-month deceleration since May 2025. This means → input-cost inflation for businesses may have peaked for now — the most intense pricing pressure has eased.
But 6.8% is still elevated. Prices are still rising, just more slowly.
What will the BOJ do next?
After the release, markets broadly concluded the BOJ does not need to hike again at its October 30 policy meeting.
In plain terms = the BOJ hiked last month; this data gives it a reason to pause and watch.
But the hiking path is not over. Overnight swap pricing — the tool traders use to bet on rate moves — shows the market expects another hike by January at the latest, with some bets on a move as early as December.
Which prices are falling and which are still rising?
Agriculture, forestry and fishery products fell 13.3% year-on-year, dragged down mainly by rice — which had surged sharply in spring 2025 and is now retreating.
Oil and coal product inflation narrowed to 11.5%, held down largely by government subsidies.
This reflects a cooling that is not broad-based: some categories are suppressed by policy subsidies, and prices could bounce back once those subsidies are withdrawn.
Are inflation expectations actually falling?
The BOJ's Tankan survey shows corporate long-term inflation expectations edged down from a record 2.6% to 2.5%.
Yet the willingness to pass costs through — intensified by Middle East conflict — remains strong. Firms are inclined to push higher input costs onto downstream customers.
In plain terms = inflation expectations are "taking root": companies have grown accustomed to raising prices and are unlikely to cut them voluntarily, even as PPI decelerates. Whether PPI continues to cool will be the key variable determining when the next hike lands.
