Mexico’s 1st half-month core Consumer Price Index (CPI) showed a modest acceleration in October 2026, underscoring persistent underlying price pressures in Latin America’s second-largest economy. The indicator rose to 0.25% in the first half of October, up from 0.17% recorded in the first half of September 2026.
The pickup in core inflation — which excludes volatile items and is closely watched as a gauge of underlying price trends — suggests that disinflation may be losing some momentum, even as headline inflation dynamics are not detailed here. The latest figures, updated on 22 October 2026, will likely feed into market expectations on the future stance of Mexican monetary policy, with investors and analysts scrutinizing whether continued core pressures could delay or limit any potential rate cuts.
While the move from 0.17% to 0.25% is incremental, it is significant in the context of central bank efforts to steer inflation sustainably toward target. Market participants will be watching upcoming releases closely to see whether October’s uptick marks a temporary fluctuation or the start of a more persistent firming in core prices.
