India’s June IIP Growth Explained: Why Strong Industrial Output Masks Weak Demand

Measure of physical output: The Index of Industrial Production, or IIP, is a composite index that measures changes in the volume of industrial production relative to a selected base year.

Industrial coverage: The current series covers mining and quarrying, manufacturing, electricity and gas supply, and water supply, sewerage and waste management.

Compiling institution: It is compiled and released by the National Statistics Office under the Ministry of Statistics and Programme Implementation.

Monthly frequency: The index is released every month with a time lag of approximately 28 days, making it one of India’s important high-frequency economic indicators.

Index value: In the base year, the index is assigned a value of 100. An index above 100 indicates that industrial production is higher than its average base-year level.

Growth rate: The year-on-year growth rate compares production in a month with production in the corresponding month of the previous year.

Example: A positive IIP growth rate means that the measured volume of industrial output was higher than a year earlier. It does not necessarily mean that every industrial sector or every factory recorded growth.

Volume rather than value: The objective is to measure real production. Where factories report production in monetary value rather than physical quantity, an appropriate price deflator is used to remove the effect of price changes.

Reference period: A base year is the period against which changes in production are measured. Its index value is normally set at 100.

Need for revision: The structure of an economy changes as new industries, products and technologies emerge while older goods lose importance. Continuing with an outdated base year can make the index less representative.

Current base: The present IIP series uses base year 2022-23, replacing the 2011-12 series.

Tenth revision: This is the tenth revision of India’s IIP base year. The first series used 1937 as its base.

Updated classification: The revised index is aligned with the National Industrial Classification 2025.

Expanded basket: The revised basket covers 1,042 products mapped to 463 item groups. It contains 120 newly added item groups, while 64 outdated or less relevant groups have been removed.

Emerging products: Newly represented goods include magnetic-stripe cards, CCTV cameras, aircraft and spacecraft parts, stents and certain vaccines.

New economic activities: The coverage has been expanded to include rare earth minerals, minor minerals, gas supply, water supply, sewerage and waste management.

Greater detail: Separate sub-indices are now available for renewable and non-renewable electricity, fuel minerals, metallic minerals, non-metallic minerals and gas supply.

Factory substitution: The revised methodology permits replacement of permanently closed or non-responsive factories with comparable units and allows newly commissioned large factories to enter the reporting panel.

Weighted index: Every sector, industry and item does not receive equal importance. Weights are assigned according to their relative contribution to industrial economic activity.

Weighting basis: Sectoral weights are derived from each sector’s share in Gross Value Added, while weights within manufacturing are distributed using Annual Survey of Industries data on GVA and Gross Value of Output.

Mathematical method: The new series uses a Laspeyres fixed-base index. It compares current production with base-period production while retaining base-year weights.

Hybrid reporting: Physical quantity is used for relatively homogeneous products. Value-based output is used where goods differ significantly in specification or quality.

Problem of price changes: If a factory reports output in rupees, a rise in value can occur either because more goods were produced or because prices increased.

Deflator: A deflator removes the effect of prices so that the remaining change better represents real production.

Methodological revision: MoSPI adopted the Output Producer Price Index in place of the Wholesale Price Index for value-reported industrial items.

Extent of change: The revision affects 234 of the 463 item groups, accounting for 36.02% of the total IIP weight. The PPI-adjusted series supersedes the initially released WPI-deflated version of the 2022-23 series.

Sectoral classification: It groups production according to the industry undertaking it, such as mining, manufacturing, electricity or water supply.

Use-based classification: It reorganises industrial goods according to their predominant economic use. The use-based classification helps analysts understand whether industrial growth is being driven by raw materials, machinery, construction activity or household consumption.

Six categories: These are primary goods, capital goods, intermediate goods, infrastructure or construction goods, consumer durables and consumer non-durables.

Natural or basic inputs: Primary goods are obtained directly from natural sources or constitute basic inputs used in further production.

Examples: Ores, minerals, petroleum fuels, natural gas and electricity are classified as primary goods.

Economic signal: Their output reflects the availability of basic energy and material inputs for the wider economy.

Means of production: Capital goods are manufactured assets used to produce other goods and services rather than being consumed immediately.

Examples: Machinery, boilers, transformers, tractors, industrial compressors and commercial vehicles may be included.

Investment indicator: Rising capital-goods production can indicate that businesses or governments are investing in new productive capacity.

Qualification: Capital-goods growth can be influenced by large individual orders, exports, public infrastructure projects or a favourable base effect. It should not automatically be interpreted as evidence of economy-wide private investment.

Inputs for further production: Intermediate goods are incomplete or semi-finished products that enter the manufacture of another product.

Examples: Steel pipes, automobile components, yarn, plywood, fasteners and industrial chemicals can serve as intermediate goods.

Supply-chain signal: Strong production may indicate rising demand from downstream factories, inventory rebuilding or expanding manufacturing supply chains.

Caution: If final consumer demand remains weak, inventories can eventually accumulate and reduce future orders for intermediate inputs.

Construction inputs: These are finished goods primarily used in infrastructure and construction activities.

Examples: Cement, bricks, tiles, railway materials, cables and certain paints are included.

Policy connection: Growth in this category may reflect public capital expenditure, housing construction, roads, railways, power networks and industrial projects.

Consumer durables: These are goods used directly by consumers and expected to last for more than one year. Examples include televisions, air conditioners, mobile phones, two-wheelers, passenger cars and pressure cookers.

Consumer non-durables: These are consumed immediately or within a relatively short period. Examples include food products, edible oils, milk, medicines, tea, coffee, biscuits and toiletries.

Economic meaning: Durables are often discretionary and sensitive to income expectations, interest rates and credit availability. Non-durables contain a large mass-consumption and essential-goods component.

Different growth engines: Total IIP is a weighted average. Rapid expansion in machinery, electrical equipment, intermediate materials and infrastructure goods can lift the headline index even when consumer-oriented industries grow slowly.

Investment-led pattern: Public infrastructure expenditure and corporate investment can generate strong demand for steel, cement, electrical equipment, commercial vehicles and machinery.

Mass-consumption weakness: Slow production of consumer non-durables can indicate pressure on the purchasing power of lower- and middle-income households, particularly when companies are unable to raise volumes.

Uneven economy: Higher-income consumers may continue buying premium products while price-sensitive consumers reduce quantities, delay purchases or shift to smaller packages. An average industrial figure may conceal this divergence.

Main conclusion: The June data point towards strong supply-side and investment activity, but not necessarily an equally broad recovery in final household demand.

No automatic equivalence: IIP measures factory production, not retail sales or household expenditure.

Inventory effect: A company may temporarily reduce production while selling goods from existing inventories. Conversely, it may increase production in anticipation of future demand even when current sales remain weak.

Exports: Some goods classified by use may be exported rather than purchased by Indian consumers.

Supply disruptions: Production can decline because of raw-material shortages, plant shutdowns, import constraints or logistics problems even when demand exists.

Category composition: Pharmaceutical products, processed foods, electronics, apparel and other industries can strongly influence consumer-goods indices for reasons not directly related to general household spending.

Correct interpretation: Persistent weakness over several quarters becomes meaningful, but it should be confirmed with sales volumes, rural and urban consumption indicators, employment, wages, credit and household expenditure data.

Largest demand component: Household consumption is measured in the national accounts through Private Final Consumption Expenditure, or PFCE. It represents expenditure by households and non-profit institutions on final goods and services.

Multiplier effect: When consumption rises, businesses receive higher sales, reduce inventories, expand production, hire workers and invest in additional capacity.

Investment-demand relationship: Businesses are more likely to invest when they expect sustained demand for their future output. Therefore, investment growth without durable consumption growth may eventually lose momentum.

Inclusive-growth dimension: Broad-based consumption indicates that income gains are reaching a larger share of the population. Premium consumption alone may coexist with stress among lower-income households.

Food and fuel inflation: Higher expenditure on food, fuel and transport leaves households with less money for discretionary purchases.

Income and employment: Weak real-wage growth, insufficient quality employment and informal-sector uncertainty can make households cautious.

Rural conditions: Agricultural income, monsoon distribution, crop prices, rural wages and government transfers influence demand for both essential and durable goods.

Borrowing costs: Interest rates and lending standards affect demand for automobiles, appliances and housing-linked goods.

Household indebtedness: Families with high loan repayments may reduce fresh consumption even when credit remains available.

Unequal recovery: Growth concentrated in capital-intensive sectors or higher-income groups may not immediately create enough mass demand.

Government capital expenditure: Public spending on roads, railways, defence, energy and urban infrastructure creates demand for machinery and construction materials.

Private investment: Some industries, including electronics, automobiles, renewable energy and data infrastructure, may be expanding capacity.

Industrial incentives: Production-linked incentives and supply-chain diversification can support investment in selected manufacturing sectors.

Replacement demand: Factories periodically replace old machinery even without constructing entirely new plants.

Export and defence orders: Capital-goods output can also rise because of foreign demand or government procurement.

Need for caution: Sustained investment requires adequate capacity utilisation, profitable demand expectations, access to finance and policy certainty.

Comparison problem: A growth rate is calculated relative to the level in the corresponding period of the previous year.

Low base: If production was unusually weak last year, even a moderate increase in current output can generate a high growth rate.

High base: Strong production in the previous year can make present growth appear weak despite a relatively high absolute output level.

Interpretation: Analysts should examine both the index level and the growth rate rather than relying only on the percentage change.

Volatility: Industrial output can fluctuate because of holidays, weather, plant maintenance, bulk orders, inventory adjustment and the timing of exports.

Quick estimates: Initial data are compiled before all reporting units have submitted final information and are subsequently revised.

Seasonality: Production patterns differ across months. The new series does not yet publish seasonally adjusted data because it requires a sufficiently long and stable time series.

Better approach: Three-month, quarterly and annual trends provide a more dependable picture than one monthly observation.

IIP: It covers a broad basket of industrial goods and is compiled by the NSO under MoSPI.

Core Industries Index: It measures output in strategically important basic industries and is compiled by the Office of the Economic Adviser under the Department for Promotion of Industry and Internal Trade.

Revised core index: The new core-industries series uses 2022-23 as its base year and includes nine industries after the addition of iron ore.

Relationship: Core-industry items form an important part of the broader IIP, but the two indices are not identical.

IIP: It is a monthly volume index of selected industrial output.

Manufacturing GVA: It measures value added by manufacturing after subtracting the value of intermediate inputs.

GDP: It measures the value of final goods and services produced across agriculture, industry and services.

Coverage difference: IIP excludes services and does not directly measure profits, wages, taxes, final expenditure or value addition.

Use in national accounts: Because it is available quickly, IIP is one of several indicators used for assessing industrial activity before more comprehensive GDP estimates become available.

Official production data: IIP is compiled from production information obtained from factories and administrative source agencies.

Business survey: The Purchasing Managers’ Index, or PMI, is based on responses from purchasing managers regarding output, new orders, employment, suppliers’ delivery times and inventories.

Different scales: IIP measures percentage change in output. PMI uses 50 as the dividing line between reported expansion and contraction.

Complementary indicators: PMI is timely and captures business sentiment, while IIP provides official production measurements. They can occasionally move in different directions.

Manufacturing leadership: Manufacturing was the principal contributor because it carries the largest weight in the IIP.

Electrical equipment: Strong growth was associated with switchgear, circuit-protection equipment, control panels, UPS systems and optical-fibre connectors.

Automobiles: Auto components, passenger cars and commercial vehicles supported motor-vehicle production.

Food products: Tea, non-basmati rice and starch products were important contributors within food manufacturing.

Unequal industry performance: Wearing apparel, wood products, petroleum refining, chemicals and pharmaceuticals showed weakness in some monthly or cumulative measures, illustrating that the industrial recovery was not universal.

Positive investment signal: Strong capital and intermediate-goods production suggests that infrastructure and industrial investment are supporting growth.

Consumption concern: Weak non-durable performance raises questions about mass-market purchasing power and the sustainability of consumption-led expansion.

Inflation-growth tension: Higher input and household prices can compress corporate margins and reduce real consumption simultaneously.

Employment issue: Capital-intensive growth can raise output without creating employment on the scale generated by labour-intensive manufacturing and services.

Fiscal dependence: If industrial growth relies mainly on public capital expenditure, maintaining momentum may require stronger private investment and consumer demand.

Policy lesson: A healthy industrial cycle should eventually become broad-based across investment, employment, wages and household consumption.

Strengthen household purchasing power: Sustainable consumption requires growth in real wages, stable employment, farm income and social protection rather than excessive dependence on household borrowing.

Control food and fuel pressures: Better food-supply management, logistics, storage, energy diversification and competition can protect disposable incomes without relying solely on demand compression.

Promote employment-intensive manufacturing: Textiles, garments, leather, food processing, furniture, tourism-linked products and MSMEs can connect industrial growth more directly with jobs and mass consumption.

Crowd in private investment: Public infrastructure expenditure should be used to reduce logistics and energy costs, thereby encouraging firms to invest on the basis of sustainable commercial demand.

Support MSME productivity: Timely payments, technology adoption, formal credit, cluster infrastructure, skilling and market access can broaden the industrial recovery beyond large capital-intensive firms.

Protect rural demand: Irrigation, crop diversification, agricultural value chains, rural infrastructure and effective implementation of employment programmes can reduce the vulnerability of consumption to monsoon shocks.

Use targeted fiscal support: Transfers or tax relief should focus on groups with a high propensity to consume while preserving medium-term fiscal sustainability.

Avoid indiscriminate credit expansion: Consumer credit can temporarily support sales but may weaken household balance sheets when income growth is inadequate.

Improve industrial diversification: India should reduce excessive dependence on a few high-growth sectors by strengthening labour-intensive exports, domestic value addition and supply-chain linkages.

Develop granular consumption indicators: Policymakers should combine IIP with PFCE, GST and e-way bills, rural wages, retail sales, employment, credit, company volumes and household-consumption surveys.

Focus on quality of growth: Industrial policy should assess not merely output growth but also employment generation, wage growth, regional spread, energy efficiency and domestic value addition.

Interpret data cautiously: Monthly IIP figures should be evaluated through rolling quarterly trends and revisions before being used for major policy conclusions.
