Portugal’s consumer price index (CPI) rose 3.6% year-on-year in September 2026, unchanged from the previous reading, according to the latest data updated on 13 October 2026. The annual inflation rate therefore remains steady, suggesting price pressures have neither intensified nor eased compared with the prior month’s dynamics.
The September figure is based on a year-over-year comparison, measuring the change in prices in September 2026 against the same month in 2025. The previous indicator, also at 3.6%, reflected the annual change recorded for the prior month on a similar year-on-year basis. The stabilization at 3.6% may signal a period of relative price stability for Portugal, with inflation neither accelerating nor decelerating on the annual horizon.
