Producers Price Index : June 2020

Reference Number: 2020-176
Release Date: 30 July 2020
Table A



The Producer Price Index (PPI, 2000=100) for manufacturing continued to descend at an annual rate of 3.9 percent in June 2020. This decrease was slightly faster than the decline of 3.7 percent in May 2020. In June of the previous year, the PPI increased at an annual rate of 1.4 percent.

The downtrend of the PPI in June 2020 can be attributed to the decreases in the indices of 12 industry groups led by paper and paper products which posted a two-digit annual decrement (-12.5%). On the other hand, furniture and fixtures, which increased by 19.7 percent, led the eight industry groups that recorded annual growth increments. (Tables A-1 and 1)

The PPI for manufacturing dropped by 0.3 percent month-on-month in June 2020, following a faster rate of decrease of 0.5 percent in May 2020. In June 2019, PPI also was at a downtrend with monthly rate of -0.2 percent.

Twelve industry groups recorded negative monthly growth rates in June 2020 with leather products posting the highest monthly decrement of 2.3 percent. On the other hand, the PPI for six industry groups posted monthly increments while the rest remained the same. (Tables A-2 and 1)

Technical Notes
  • Introduction
The Philippine Statistics Authority generates various price indices, one of which is the Producer Price Index (PPI). The PPI is generated from the results of the Producer Price Survey (PPS) which is conducted nationwide. The survey gathers monthly producer prices of selected products included in the market basket of PPI from sample establishments.
The PPI is used as a deflator of the Monthly Integrated Survey of Selected Industries (MISSI) to derive indicators for the Volume of Production Index (VoPI) and Volume of Net Sales (VoNSI).
  • Method of Index Computation
PPI utilizes the Paasche-type method of index computation. The weights are computed from the value of production from the Census of Philippine Business and Industry (CPBI) or Annual Survey of Philippine Business and Industry (ASPBI). The weights are updated as soon as new results of the ASPBI or CPBI are available and these are applied at the beginning of each survey year.
For the 2020 PPI, the weights of the major industry groups and industry classes were computed based on the final results of the 2017 ASPBI for Manufacturing establishments with total employment of 20 and over.
The computation of PPI adopts the following formula:
Formula 1
Formula 2
Formula 3


Starting with the January 2017 PPI, a link factor has been used to adjust weight effects to measure the correct price change.


  • Computation of Growth Rates

Year-on-year growth rates are computed by dividing the current month index by the index in the same month of the previous year less 1.

Month-on-month growth rates are computed by dividing the current month index by the previous month’s index less 1.

  • Imputation and Revision

Imputation is done for sample establishments that are in operation during the reference period but no received response during the release date. Results are revised accordingly when the actual data are received and these revisions are reflected in the next release.


  • Industry Coverage

Starting with the January 2013 reference month, the PPI utilizes the 2009 Philippine Standard Industrial Classification (PSIC) to classify sectors and industries. Selected industry classes of the 2009 PSIC were grouped to form the 20 major industry groupings of the 2020 PPS. These are presented in the table below.
