Mexico’s month-over-month core inflation eased in September 2026, with the annualized indicator slipping to 3.75% from 3.88% in August 2026, according to data updated on 8 October 2026. The latest figure indicates a continued moderation in underlying price pressures in Latin America’s second-largest economy.

The September reading reflects a comparison of price changes in that month versus August, while the prior 3.88% figure measured the change in August against July. The gradual slowdown suggests that core inflation—closely watched for its exclusion of volatile items—is moving further away from earlier peaks and may provide policymakers with more room to maneuver on monetary policy in the coming months.

The downward shift from August to September reinforces the view that inflationary dynamics are cooling on a sequential basis, an important signal for markets tracking the trajectory of Mexican interest rates and broader financial conditions.
