Core CPI
Core CPI is the consumer price index that excludes regulated and seasonal items — such as administered prices, energy, and certain food products — to capture underlying price dynamics. The precise coverage of core CPI varies across countries. This Core CPI series is part of the Latin Macro Watch (LMW) database maintained by the Inter-American Development Bank (IDB) on data.iadb.org, giving economists, central-bank watchers, and journalists a harmonized measure of underlying inflation pressure across Latin America and the Caribbean.
Coverage
The series spans 10 countries across Latin America and the Caribbean at annual, monthly, and quarterly frequency, covering the period 1990–2026. Index values are available in several forms, including a base index, an index rebased to 2023 = 100, and year-to-date (YTD) variants, each reported as an average of period or end of period. Month-on-month (MoM %), quarter-on-quarter (QoQ %), and year-on-year (YoY %) transformations support inflation-trend analysis.
Sources
Data are compiled from official national statistical offices and central banks, including INEGI - Mexico, INDEC - Argentina, the Banco Central de El Salvador, and the Central Statistical Office of Trinidad & Tobago. The IDB standardizes these national sources into a comparable cross-country dataset.
