The Pakistan Bureau of Statistics’ consumer price release for September 2026, published on 1 October, reported monthly inflation of 1.27% and annual inflation of 10.26%. The monthly rate compares the September 2026 index with August 2026, while the annual rate compares September 2026 with September 2025. The Bureau also reported average inflation of 10.20% for the July–September 2026–27 quarter against the same quarter of the previous fiscal year. The three figures cover different reference periods.

The monthly increase was 1.31% in urban areas and 1.23% in rural areas. On an annual comparison, the urban CPI rose 10.12% and the rural CPI 10.47%. The national index is a weighted combination of the urban and rural indexes, so the national rate should not be read as a simple arithmetic average of the two regional rates. The quarterly average also summarizes a comparison for the entire July–September quarter, rather than only the price movement in September.

In the release’s monthly group table, housing, water, electricity, gas and other fuels rose 3.05% nationally, while transport rose 5.75%. Food and non-alcoholic beverages increased 0.19%. The stronger monthly movement in transport illustrates why the headline 1.27% does not mean every group rose by the same amount. A group rate measures the monthly movement in that group’s own price index; it is not the same as that group’s contribution to the overall index.

The annual table also shows different movements: housing, water, electricity, gas and other fuels increased 12.39%; transport rose 27.43%; and food and non-alcoholic beverages rose 8.20%. Their weights differ as well. Food accounts for 34.58% of the national basket, housing and energy for 23.63%, and transport for 5.91%. A high group inflation rate alone does not establish that the group made the largest contribution to annual inflation; contribution depends on both the price movement and the weight.

PBS’s CPI is an index based on 2015–16. Its stated coverage includes 35 cities and 356 consumer items for the urban CPI, and 27 rural centres and 244 items for the rural CPI. The national CPI for 12 major expenditure groups is calculated as a weighted average of the urban and rural indexes. It represents price changes for selected goods and services. It does not mean every household buys the same items in the same quantities or experiences a cost of living identical to the national rate.

The reference periods need to remain clear. September’s 1.27% is a month-on-month price change; 10.26% compares with the same month a year earlier; and 10.20% compares the July–September quarterly average with the corresponding quarter of the previous fiscal year. These are not components that can be added together or interchangeable alternatives. The release also provides urban and rural series; the national index combines those areas using weights.

These figures track price-level movement; they do not directly measure wages, household income, quantities purchased, or business costs. A single month’s increase is not enough to establish a lasting trend. The PBS release is the official source for index changes and the weighted coverage described above. It should also be kept distinct from Pakistan’s weekly Sensitive Price Indicator: the SPI is a separate weekly measure, whereas this CPI is monthly, uses a 2015–16 base, and combines urban and rural consumer-price indexes.
