Iran Chamber of Commerce, Industries, Mines, and Agriculture (ICCIMA) has released the country’s new PMI data for the fiscal month of Azar (November 22 – December 21, 2025) which signals contraction continues across the economy.

The seasonally adjusted composite PMI was registered at 48.9, below the neutral 50 threshold that separates expansion from contraction.

The December PMI continued to fall for the 21st consecutive month although it has fallen less sharply compared to 46.6 of the preceding month.

According to the new reading, four out of the five main sub-indexes – business activities, suppliers’ delivery time, raw material inventory and employment – have declined in the month under review.

Seasonal adjustment, or deseasonalization, is a statistical method used to remove the seasonal component from a time series, allowing for the independent analysis of trends and cyclical deviations. After preparing dozens of PMI (Purchasing Managers’ Index) reports, the Research Center of Iran Chamber of Commerce, Industries, Mines, and Agriculture has now identified the seasonal components of these time series and prioritized seasonal adjustment in its monthly PMI reports.

The ICCIMA’s Statistics and Economic Analysis Center, the sponsor and coordinator of the survey, announces the whole economy PMI data in a report every month.

The headline PMI is a number from 0 to 100, such that over 50 shows an expansion of the economy when compared with the previous month. A PMI reading under 50 indicates contraction and a reading of 50 implies no change.

PMI is an index of the prevailing direction of economic trends, aiming to provide information about business conditions to company directors, analysts and purchasing managers.
