Wholesale Price Index (WPI)

The Wholesale Price Index (WPI) measures the average change in the prices of goods at the wholesale level, generally before they reach the retail market. It typically captures price movements of raw materials, intermediate goods and other bulk commodities, and is used to monitor inflationary pressures at the production and distribution stages. Specific coverage and methodology may vary across countries. Part of the Inter-American Development Bank (IDB) Latin Macro Watch, this indicator helps researchers, policymakers and journalists track upstream price dynamics across Latin America and the Caribbean.

Coverage

The series covers 6 countries across Latin America and the Caribbean at annual, monthly and quarterly frequency over the period 1990–2026. Values are available as an index (including a 2023 = 100 base, average-of-period and end-of-period variants) and on a year-to-date (YTD) basis, with month-on-month (MoM %), quarter-on-quarter (QoQ %) and year-on-year (YoY %) transformations.

Sources

Data are compiled by the IDB from national statistical agencies and central banks, including INDEC - Argentina, the Banco Central de Venezuela, INEC - Panamá, the Instituto Nacional de Estadística Guatemala, the Instituto Nacional de Estadística de Bolivia and the Instituto Nacional de Estadística e Informática de Perú.

Data notes	What does the Wholesale Price Index (WPI) measure? It measures the average change in the prices of goods at the wholesale level, generally before they reach the retail market, typically covering raw materials, intermediate goods and bulk commodities. How does it differ from a consumer price index? The WPI captures prices upstream — at the production and distribution stages — while a consumer price index measures prices paid by households at the retail level. How many countries and what period does it cover? It covers 6 countries across Latin America and the Caribbean at annual, monthly and quarterly frequency over 1990–2026. What units and transformations are available? Values are available as an index (including a 2023 = 100 base and average/end-of-period variants) and on a year-to-date basis, with MoM %, QoQ % and YoY % changes. Where does the data come from? The IDB compiles the series from national statistical agencies and central banks, including INDEC - Argentina, the Banco Central de Venezuela, INEC - Panamá, the Instituto Nacional de Estadística Guatemala, the Instituto Nacional de Estadística de Bolivia and the Instituto Nacional de Estadística e Informática de Perú. What is the Wholesale Price Index used for? It is used to monitor inflationary pressures at the production and distribution stages and to anticipate price movements that may later pass through to consumers. How do I cite this indicator?
