FX.co ★ Mexico’s Mid-October Inflation Accelerates as 1st Half-Month CPI Rises to 0.41%

Mexico’s consumer prices picked up pace in mid-October, with the 1st half-month Consumer Price Index (CPI) advancing to 0.41% in October 2026, up from 0.33% recorded in mid-September 2026. The latest reading, updated on 22 October 2026, indicates a modest acceleration in price pressures compared with the previous half-month period.

The uptick from 0.33% to 0.41% suggests that inflationary dynamics remain present in the Mexican economy at the start of the fourth quarter. While the magnitude of the increase is not dramatic, the sequential rise will be closely watched by market participants and policymakers monitoring the trajectory of consumer prices and its implications for monetary policy and household purchasing power.

The fresh October data add another reference point for investors assessing the near-term inflation path in Mexico. Any continued firming in the 1st half-month CPI could influence expectations around interest rate decisions and broader financial conditions as the year progresses.
