FX.co ★ Mexico’s Core Inflation Re-Accelerates in January, Raising Policy Questions

Mexico’s core Consumer Price Index (CPI) quickened in January 2026, signaling renewed inflationary pressure at the start of the year. Month-over-month, core CPI rose 0.60%, up from a 0.41% increase recorded in December 2025, according to data updated on 9 February 2026.

The comparison is made on a month-over-month basis, meaning January’s 0.60% reflects the change versus December 2025, while December’s 0.41% measured the change against November 2025. The acceleration suggests that underlying price pressures—stripped of more volatile components—are firming again, a development likely to be watched closely by investors and policymakers assessing the trajectory of Mexican inflation and the potential implications for monetary policy in the coming months.
