Year-on-Year

The Producer Price Index (PPI) for manufacturing continued at a downward trend with an annual rate of -2.4 percent in June 2021. This decrease was slower than the -4.1 decline percent in May 2021. In June 2020, the PPI likewise dropped with an annual rate of -5.3 percent.  (Table A)

The downturn in the PPI in June 2021 can be attributed to the annual contractions in the indices of nine industry divisions led by manufacture of computer, electronic, and optical products which posted a double-digit annual decrement of -19.6 percent. On the contrary, manufacture of coke and refined petroleum products, with an annual increase of 9.8 percent, led the 13 industry divisions that recorded positive annual growth rates.  (Tables A-1, and 1)

Month-on-Month

Month-on-month, the PPI for manufacturing increased by 0.8 percent in June 2021, following a decrease of -0.3 percent in May 2021. In June 2020, the PPI posted a monthly decline of -1.0 percent.  (Table A)

Fifteen industry divisions registered positive monthly growth rates in June 2021 led by manufacture of wood, bamboo, cane, rattan articles and related products with monthly increment of 4.3 percent. On the other hand, the PPI of six industry divisions recorded monthly decrements, with manufacture of wearing apparel posting the highest monthly decrement of -2.4 percent. The monthly growth rate of manufacture of tobacco products remained the same.  (Tables A-2 and 1)

Technical Notes
 
  • Introduction
Starting January 2021 reference period, the Producer Price Index (PPI) for Manufacturing uses 2018 as base year, from 2000 base period. The PPI for Manufacturing measures the changes in the producer price of key commodities produced by the Manufacturing sector. One of its uses is as a deflator to derive the Volume of Production Index (VoPI) and Volume of Net Sales Index (VoNSI).
 
The PPI for Manufacturing 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.
 
  • Method of Index Computation
The PPI utilizes the chained Paasche-type method of index computation where the base year is normalized. 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), whichever is the more recent. The weights are updated as soon as new results of the CPBI or ASPBI are available and these are applied at the beginning of each survey year.
 
For the 2021 PPI, the base year is 2018 and the weights of the industry divisions and industry groups were computed based on the final results of the 2018 CPBI for Manufacturing establishments with total employment of 20 and over.
 
The computation of PPI adopts the following formula:
 
Formula 1
Formula 2
 
 
 
Formula 3

  • Computation of Growth Rates

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

Month-on-month growth rates are computed by dividing the current month’s 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 with 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, PPI utilizes the 2009 Philippine Standard Industrial Classification (PSIC) to classify sectors and industries. Selected industry groups of the 2009 PSIC were grouped to form the 22 industry divisions of the 2021 PPS. These are presented in the table below.
