PRODUCER PRICE INDICES FOR THE QUARTER ENDING SEPTEMBER, 2025

Introduction The National Bureau of Statistics hereby releases the Producer Price Index (PPI) for the third quarter July-September of 2025. The PPI measures the average change over time in the prices received by selected domestic producers for the production of goods. A basket includes a list of selected commodities of goods that are being priced on quarterly basis. The producer prices are collected as at 15 th of the mid-month of every quarter that is; (Q1: January -March), (Q2: April -June), (Q3: July -September) and (Q4: October-December).

Weights and a Reference Period The index weights are based on gross output derived from the 2015 Annual Survey of Industrial Production (ASIP 2015). The P PI on this release reports the indices with reference to the Fourth Quarter (October -December) of the year 2018(2018Q4=100). The result shows the producer price changes since December 2018 up to the third quarter of 2025, the index has been linked back up to the first quarter of the year 2013 to show the trend of price movements on three major sub -sectors of industry (Mining, Manufacturing, and Utilities).

Classification Industrial Classification follows the International Standard Industrial Classification of All Economic Activities (ISIC) Rev.4.

Methodology In the process of deriving the structure and weights, a top -down approach was adopted in order to maximize the indirect representation of industries and items. The basket was selected and base weights were calculated from Gross Output (GO) based on The

During the process of weights calculation, establishments with a contribution of at least 80% of Gross Output were selected in each ISIC Rev.4 Group. A sample of establishments for inclusion in the price survey was then selected using cut-off sampling procedures.

The first level of aggregation is the class 4-digit ISIC; these indices are the un-weighted Elementary Aaggregates (EA) and are being compiled using the Jevons geometric mean aggregation formula which refers to the Geometric Mean of the price relatives.
The Elementary Aggregates indices are then being progressively combined with higher levels within the index structure (i.e. Group 3-digit, 2-digit division and 1-digit Section levels of the ISIC, and then the all -groups level s) using the standard base -weighted Laspeyres formula.
