IMACEC

.

The Monthly Economic Activity Index (Imacec) is an estimate that summarizes the activity of the different branches of the economy in a given month, at prices from the previous year; its inter-annual variation constitutes an approximation of GDP evolution. The calculation of the Monthly Economic Activity Index is based on multiple supply indicators, which are weighted by the share of economic activities in the previous year’s GDP.

The Monthly Economic Activity Index is published on the first business day of each month taking into account a lag of 31 days in relation to the month being measured. In addition to this, a breakdown is published which distinguishes mining from all other activities —mining and non-mining series—, as well as the series at factor cost. All series are presented in both original and seasonally adjusted figures.

Consistent with the established publication policy, the Monthly Economic Activity Index series are revised along with the quarterly and annual national accounts.

June 2026's monthly indicator of economic activity, Imacec

According to preliminary information, the Imacec increased 2.4% in June 2026, compared with the same month of the previous year (Table 1). The seasonally adjusted series rose 0.6% from the previous month and 1.4% annually. The month came with one more working day than June 2025.

The Imacec result reflected an increase in the mining, services and the wholesale and retail trade industries (Figure 1). The same industries contributed to the increase in the seasonally adjusted Imacec (Figure 2).

The non-mining Imacec grew 1.4% compared with the same month of the previous year, while the seasonally adjusted series rose 0.1% from the previous month and 0.4% annually.

Analysis by industry

1. Goods-producing industries

Goods-producing industries increased 3.9% compared with the same month of the previous year. This result reflected an increase in the mining sector, particularly in copper mining. Other goods-producing industries grew 1.1% while manufacturing decreased 0.7%, driven by a lower processing and preserving of fish.

The seasonally adjusted series for goods-producing industries increased 0.7% from the previous month, mainly driven by a growth in copper mining.

2. Wholesale and retail trade

Wholesale and retail trade grew 5.4%, compared with the same month of the previous year. All trade categories showed positive results, wholesale trade being the largest contributor to growth. Wholesale trade increase was driven by sales of machinery and equipment. Major contributors to retail trade increase were sales of clothing and food in specialized stores and online sales. Sales and repairs of motor vehicles also contributed positively.

The seasonally adjusted series for wholesale and retail trade rose 1.5% from the previous month, mainly driven by growth in wholesale trade, followed by retail trade and sales and repairs of motor vehicles.

3. Services sector
