Mexico’s consumer price momentum accelerated in September 2026, with the month‑over‑month Consumer Price Index (CPI) rising 0.42%, more than double the 0.20% increase recorded in August. The fresh data, updated on 8 October 2026, point to a renewed pickup in price pressures after a comparatively subdued reading the month before.
On a month‑over‑month basis, the latest figure shows that prices in September grew at a significantly faster pace than in August, when the indicator had essentially stabilized at a modest 0.20%. The comparison framework means September’s “actual” reading reflects the change from August to September 2026, while the “previous” figure captured the change from July to August 2026.
The sharper uptick in September’s CPI suggests that inflationary forces may be re‑emerging after a brief easing in late summer. While no breakdown by component was provided, the move higher will likely draw close attention from market participants and policymakers monitoring whether this marks the start of a new inflation trend or a one‑off monthly spike.
