Tarlac’s CPI was at 116.7 in April 2022
Consumer Price Index (CPI) is an indicator of the changes in the average retail prices of a fixed basket of goods and services commonly purchased by households relative to a base year. The CPI is most widely used in the calculation of the inflation rate and purchasing power of peso. It is a major statistical series used for economic analysis and as a monitoring indicator of the government’s economic policy.
The Survey of Retail Prices of Commodities conducted by the Philippine Statistics Authority (PSA) has generated a CPI of 116.7 as of April 2022 for the province of Tarlac, using 2018 as the base year. This means that for a typical Filipino household in the province to afford the same values of goods and services in April 2018 at Php100.00, needs an additional Php16.7 in April 2022. The CPI April 2022 was recorded at 116.7 and in April 2021 at 111.4 using 2018 as the base year. See Figure 1
In April 2022, commodities under Alcoholic Beverages and Tobacco recorded the highest CPI at 179.1. This was followed by the commodity groups of Financial Services at 146.0, followed by the commodity groups of Transport at 136.8, Furnishings, Household, Equipment and Routine Household Maintenance at 120.5, and the commodity group of Health at 117.5. On the other hand, CPIs lower than the provincial average was observed in the commodity groups: Housing, Water, Electricity, Gas, and Other Fuels at 116.6, Recreation, Sport and Culture at 115.2, Clothing and Footwear at 113.2, Restaurants and Accommodation Services at 112.9, Personal Care, and Miscellaneous Goods and Services at 111.4, Food and Non-Alcoholic Beverages at 111.0, Information and Communication at 105.0, and Education Services at 98.9. See Table 1
Tarlac’s Inflation at 4.8% and Purchasing Power of Peso at Php 0.86 in April 2022
The inflation rate is the annual rate of change or the year-on-year change of the CPI expressed in percent. Inflation is interpreted in terms of declining purchasing power of money.
The inflation rate in the province of Tarlac went up to 4.8% in April 2022 compared to 3.9% in March 2022. The inflation rate was 6.0% in April 2021. The purchasing power of peso in the province is 86 centavos for the month of April 2022.
This implies that if you paid Php15.00 for a can of sardines in April 2021 and if on average, prices went up by 4.8% after a year’s time, you will now need Php15.72 to buy the same brand of a can of sardines in April 2022. See Table 2.
The highest inflation among the commodity groups in April 2022 was observed in the indices of seven out of thirteen commodity groups: Transport (11.9%), Housing, Water, Electricity, Gas and Other Fuels (11.3%), Alcoholic Beverages and Tobacco (7.2%), Recreation (5.4%), Heath (5.0%). These commodity groups were higher than the provincial average of 4.8%. On the other hand, the commodity groups lower than the provincial average of 4.8% are the Furnishings, Household, Equipment and Routine Household Maintenance (3.7%), Clothing and Footwear (3.5%), Personal Care, and Miscellaneous Goods and Services (3.0%), Food and Non-Alcoholic Beverages (2.2%), Information and Communication (1.8%), Education Services (0.0%) and Financial Services (0.0%).
However, negative inflation was recorded in the indices of Restaurants and Accommodation Services (-0.7%). See Table 3.
On selected food and non-alcoholic beverages items, negative inflation was recorded in the following groups:
• Fruits and Nuts (-7.7%)
• Water (-4.2)
• Milk, other dairy products, and eggs (-1.7%)
Meanwhile, Oils and fats (18.4%), Vegetables, tubers, plantains, cooking bananas and pulses (11.4%), Sugar, confectionery and desserts (10.0%), Soft drinks (6.5%), and Cocoa drinks (5.0%), and Coffee and coffee substitutes (5.0%) had the highest inflation rates, higher than the average Inflation Rate. See Table 4.
Purchasing Power of Peso (PPP) remained at 0.86
Purchasing Power of Peso (PPP) shows how much the peso in the base period is worth in the current period. It is computed as the reciprocal of the CPI for the period under review multiplied by 100. The PPP is inversely related to the inflation rate. Thus, as the inflation rate increases, PPP declines.
The PPP in April 2022 was 0.86. This implies that the Php1.00 in April 2018, as the base year, values only Php0.86 in April 2022. The PPP during the same month of 2021 was 0.90. The PPP recorded in March 2022 was 0.86. See Figure 2.
Computation of Consumer Price (CPI)
The computation of the CPI involves consideration of the following important points:
a. Base Period – The reference date or base period is the benchmark or reference date or period at which the index is taken as equal to 100.
b. Market Basket – A sample of the thousand varieties of goods purchased for consumption and services availed by the households in the country selected to represent the composition price behavior of all goods and services purchased by consumers.
c. Weighting System – The weighting pattern uses the expenditures on various consumer items purchased by households as a proportion to total expenditure.
d. Formula – The formula used in computing the CPI is the weighted arithmetic mean of prices relatives, the Laspeyre’s formula with a fixed base year period (2006) weight.
e. Geographic Coverage – CPI values are computed at the national, regional, and provincial levels, and for selected cities.
Inflation Rate is the rate of change of the CPI expressed in percent. Inflation is interpreted in terms of the declining purchasing power of peso.
Headline Inflation refers to the rate of change in the CPI, a measure of the average standard “basket” of goods and services consumed by a typical family.
Purchasing Power of Peso shows how much the peso in the base period is worth in the current period. It is computed as the reciprocal of the CPI for the period under review multiplies by 100.
