The newly released Japan core CPI for September 2026 (Q3 2026) reached 102.3, climbing steadily from the previous value of 102.0. Although the data series provided by DataTrack recently showed a base period drop discrepancy, the index's rebounding trend is consistent with the external market consensus of a 2.1% YoY growth rate in the September core CPI. The spreading pressure of rising prices has significantly boosted market calls for a Bank of Japan rate hike in December.
