FX.co ★ Colombia’s Monthly Inflation Eases Slightly in September, CPI Slips to 0.37%

Colombia’s consumer price inflation edged down in September 2026, with the month‑over‑month Consumer Price Index (CPI) slowing to 0.37%, compared with 0.39% in August 2026. The latest data, updated on 7 October 2026, point to a marginal moderation in price pressures as the pace of monthly increases cooled slightly.

The comparison is based on month‑over‑month changes, meaning September’s figure reflects how prices moved relative to August, while the previous indicator captured August’s change versus July. Although the move from 0.39% to 0.37% is modest, it signals a small step toward more contained inflation dynamics in the Colombian economy as the third quarter of 2026 draws to a close. Investors and policymakers will be watching upcoming releases closely to assess whether this easing trend can be sustained in the months ahead.
