Year-on-Year
The Producer Price Index (PPI) for manufacturing continued at downtrend with an annual rate of -1.5 percent in July 2021. This decline was slower than the annual drop of -2.6 percent in June 2021. In July 2020, the PPI similarly registered a downturn with an annual rate of -4.8 percent. (Table A)
The decline in the PPI in July 2021 can be attributed to the annual decreases in the indices of seven industry divisions led by manufacture of wood, bamboo, cane, rattan articles and related products which posted a double-digit annual decrement of -22.2 percent. On the other hand, manufacture of coke and refined petroleum products, with an annual increase of 15.7 percent, led the 15 industry divisions that recorded positive annual growth rates. (Tables A-1 and 1)
Month-on-Month
Month-on-month, the PPI for manufacturing in July 2021 registered the same growth rate with that of June 2021 at 0.8 percent. In July 2020, the PPI posted a monthly decrease at -0.2 percent. (Table A)
Sixteen industry divisions recorded positive monthly growth rates in July 2021 led by manufacture of coke and refined petroleum products with monthly increment of 5.9 percent. On the contrary, the PPI of three industry divisions recorded monthly decrements, with manufacture of wood, bamboo, cane, rattan articles and related products posting the highest monthly decrement of -7.3 percent. The monthly growth rates of other three industry divisions were at 0.0 percent. (Tables A-2 and 1)

- Introduction
- Method of Index Computation
- 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.
