PRODUCER PRICE INDICES FOR THE QUARTER ENDING DECEMBER, 2025
Introduction The National Bureau of Statistics hereby releases the Producer Price Index (PPI) for the fourth quarter October-December of 2025. The P PI 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 fourth 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

Annual Survey of Industrial Production of 2015. 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.

Note: There has been a revision of the index for the third quarter 2025 (July -Sept 2025), from 118.69 to 119.24 . This change resulted from the late receipt of questionnaires, which caused the index for in manufacturing of food products change to 135.57, compared to the previously reported 132.72.
Overall index recorded an increase of 0. 07 percent from 119.24 in third quarter of 2025 to 11 9.32 in fourth quarter of 2025. An increase was attributed to manufacture of machinery and equipment n.e.c. by 1.89 percent followed by manufacture of beverages by 1.66 percent and manufacture of chemicals and chemical products by 1.36 percent. On the other hand, manufacture of leather and related products decreased by 1.61 percent followed by manufacture of paper and paper products by 1.39 percent and manufacture of coke and refined petroleum products by 1.17 percent.
Looking at the percentage change for the corresponding quarter (fourth quarter of 2024 to fourth quarter of 2025), the overall index increased by 2.44 percent, rising from 116.48 in the fourth quarter of 2024 to 119.32 in the fourth quarter of 2025. This growth was mainly driven by an increase in the manufacture of food products, which rose by 7.24 percent, followed by the manufacture of beverages at 5.27 percent and the manufacture of paper and paper products at 4.38 percent. Conversely, some subsectors recorded declines during the same period. The manufacture of coke and refined petroleum products decreased by 7.94 percent, followed by the manufacture of leather and related products, which declined by 1.61 percent, and printing and reproduction of recorded media, which fell by 0.81 percent.
