Mexico’s inflation unexpectedly accelerated in November, casting doubt on the timing and pace of monetary easing by the central bank. Consumer prices rose 3.80% year-on-year, above both the 3.70% consensus forecast and October’s 3.57% reading, according to data from INEGI. Core inflation, which strips out volatile food and energy components, also edged higher to 4.43%, remaining well above the upper bound of Banco de México’s 3% ±1 percentage point target.
The inflation data arrive just days before Banxico’s final monetary policy meeting of the year, where a 25-basis-point rate cut had been broadly anticipated. The central bank had previously signaled a likely reduction at its December 18 meeting, potentially bringing the benchmark rate to 7.0%. However, the persistence of core inflation may prompt a more cautious stance, particularly as the institution seeks to preserve its inflation-targeting credibility amid growing scrutiny.
Electricity tariffs, public transport fares, and prepared food prices were among the main contributors to the November increase, while some agricultural goods such as avocados and potatoes saw price declines. The mixed composition suggests that while some of the pressure may be seasonal or transitory, underlying inflationary dynamics remain sticky—especially in services and administered prices.
Persistent core inflation may delay Banxico’s easing cycle and test its inflation-targeting credibility.
This stickiness is particularly problematic given the broader macroeconomic backdrop. Banxico recently halved its 2025 GDP growth forecast to just 0.3%, citing weak domestic demand. Sluggish growth would typically ease inflationary pressures over time, but the resilience of core inflation complicates that narrative. Some board members still expect headline inflation to converge toward target by the third quarter of 2026, but the path appears increasingly uncertain.
The central bank’s credibility is under strain. One board member recently warned of a potential crisis of confidence if Banxico fails to rein in inflation effectively—its primary mandate. Investors are watching closely for signs of policy consistency, especially as inflation surprises can ripple through exchange rates and asset prices in an already volatile external environment.
While a December rate cut remains on the table, the latest data may shift expectations for subsequent moves. Banxico has already hinted at a possible pause in February 2026, and any further evidence of entrenched inflation could extend that pause or even halt the easing cycle altogether. For investors and businesses operating in Mexico, this introduces an additional layer of monetary uncertainty at a time when clarity is in short supply.
