Taiwan’s consumer price inflation accelerated modestly in September 2026, with the month‑over‑month Consumer Price Index (CPI) rising 0.17%, up from a 0.13% increase in August 2026. The latest data, updated on 7 October 2026, point to a mild firming in price momentum across the economy.
On a month‑over‑month basis, the September figure reflects a slightly faster pace of price gains compared with the previous month, when August’s CPI increase of 0.13% was measured against July levels. The current 0.17% reading similarly compares September prices to those in August, in line with the standard methodology for monthly CPI tracking.
While the uptick remains small in absolute terms, the back‑to‑back increases suggest that price pressures, though still contained, are inching higher. Investors and policymakers will be watching upcoming releases closely to determine whether this represents the start of a more pronounced inflation trend or a temporary fluctuation in monthly price dynamics.
