Story
How fast factory, mine and power output grew, compared with the same month last year.
What is happening now As of Sep 2026
Industrial output grew 6.7% in September 2026 over September 2025, by the quick estimate of 28 October 2026. Growth slowed from 7.8% in August (final estimate). The National Statistics Office (NSO) says manufacturing grew 7.6% and electricity and gas supply 11.2%, while mining and quarrying fell 6.2%.
Within manufacturing, 17 of 23 industry groups grew; motor vehicles (19.0%), electrical equipment (33.9%) and rubber and plastics products (19.9%) contributed most. By use, intermediate goods grew 12.2% and capital goods 10.4%, while consumer non-durables grew only 1.4%. From April to September 2026, output grew 6.8%, against 4.4% in the same months of 2025.
Why it matters
Factories, mines and power plants turn raw materials into goods and employ millions of people. When the Index of Industrial Production (IIP) rises, factories are running harder, which usually means more orders for suppliers, more freight and more hiring. A fall warns of weaker demand for goods.
The index comes every month, while Gross Domestic Product (GDP) comes every quarter, so it is one of the earliest official signs of whether the economy is speeding up or slowing. The National Statistics Office (NSO) uses it to estimate industry's part of quarterly GDP. Its use-based groups show where demand comes from: investment (capital goods), building (infrastructure and construction goods) or households (consumer goods).
What it is
The Index of Industrial Production (IIP) measures the volume of output in mining, manufacturing, electricity and, since 2026, water supply and waste management.
Manufacturing carries about 76% of the weight in the 2022-23 series.
The first figure for a month is a quick estimate. The National Statistics Office (NSO) revises it in the next month's release.
