Mumbai

Cement manufacturers have welcomed the Union Budget 2026–27’s strong infrastructure thrust, with public capital expenditure increased to Rs 12.2 trillion, saying it reinforces infrastructure as the central engine of economic growth and strengthens medium-term prospects for the cement sector. In a statement, the Cement Manufacturers’ Association (CMA) has welcomed the Union budget 2026-27 for reinforcing the ambitions for the nation’s growth balancing the aspirations of the people through inclusivity inspired by the vision of Narendra Modi, Prime Minister of India, for a Viksit Bharat by 2047 and Atmanirbharta.

The budget underscores India’s steady economic trajectory over the past 12 years, marked by fiscal discipline, sustained growth and moderate inflation, and offers strong demand visibility for infrastructure linked sectors such as cement.

The Budget’s strong infrastructure push, with public capital expenditure rising from Rs 11.2 trillion in fiscal year 2025–26 to Rs 12.2 trillion in fiscal year 2026–27, recognises infrastructure as the primary anchor for economic growth creating positive prospects for the Indian cement industry and improving long term visibility for the cement sector. The emphasis on Tier 2 and Tier 3 cities with populations above 5 lakh and the creation of City Economic Regions (CERs) with an allocation of Rs 50 billion per CER over five years, should accelerate construction activity across housing, transport and urban services, supporting broad based cement consumption.

Logistics and connectivity measures announced in the budget are particularly significant for the cement industry. The announcement of new dedicated freight corridors, the operationalisation of 20 additional National Waterways over the next five years, the launch of the Coastal Cargo Promotion Scheme to raise the modal share of waterways and coastal shipping from 6 per cent to 12 per cent by 2047, and the development of ship repair ecosystems should enhance multimodal freight efficiency, reduce logistics costs and improve the sector’s carbon footprint. The announcement of seven high speed rail corridors as growth corridors can be expected to further stimulate regional development and construction demand.

Commenting on the budget, Parth Jindal, President, Cement Manufacturers’ Association (CMA), said, “As India advances towards a Viksit Bharat, the three kartavya articulated in the Union Budget provide a clear context for the Nation’s growth and aspirations, combining economic momentum with capacity building and inclusive progress. The Cement Manufacturers’ Association (CMA) appreciates the Union Budget 2026-27 for the continued emphasis on manufacturing competitiveness, urban development and infrastructure modernisation, supported by over 350 reforms spanning GST simplification, labour codes, quality control rationalisation and coordinated deregulation with States. These reforms, alongside the Budget’s focus on Youth Power and domestic manufacturing capacity under Atmanirbharta, stand to strengthen the investment environment for capital intensive sectors such as Cement. The Union Budget 2026-27 reflects the Government’s focus on infrastructure led development emerging as a structural pillar of India’s growth strategy.”

He added, “The Rs 200 billion CCUS outlay for various sectors, including Cement, fundamentally alters the decarbonisation landscape for India’s emissions intensive industries. CCUS is a significant enabler for large scale decarbonisation of industries such as Cement and this intervention directly addresses the technology and cost requirements of the Cement sector in context. The Cement Industry, fully aligned with the Government of India’s Net Zero commitment by 2070, views this support as critical to enabling the adoption and scale up of CCUS technologies while continuing to meet the Country’s long term infrastructure needs.”

Dr Raghavpat Singhania, Vice President, CMA, said, “The government’s sustained infrastructure push supports employment, regional development and stronger local supply chains. Cement manufacturing clusters act as economic anchors across regions, generating livelihoods in construction, logistics and allied sectors. The budget’s focus on inclusive growth, execution and system level enablers creates a supportive environment for responsible and efficient expansion offering opportunities for economic growth and lending momentum to the cement sector. The increase in public capex to Rs 12.2 trillion, the focus on Tier 2 and Tier 3 cities, and the creation of City Economic Regions stand to strengthen the growth of the cement sector. We welcome the budget’s emphasis on tourism, cultural and social infrastructure, which should broaden construction activity across regions. Investments in tourism facilities, heritage and Buddhist circuits, regional connectivity in Purvodaya and North Eastern States, and the strengthening of emergency and trauma care infrastructure in district hospitals reinforce the cement sector’s role in enabling inclusive growth.”

CMA also noted the Government’s continued commitment to fiscal discipline, with the fiscal deficit estimated at 4.3 per cent of GDP in FY27, reinforcing macroeconomic stability and investor confidence.

Going forward, domestic steel mills are targeting capacity expansion
of nearly 40 per cent through till FY31, adding 80-85 mt, translating
into an investment pipeline of $ 45-50 billion. So, Jhunjhunwala points
out that continuing the safeguard duty will be vital to prevent a surge
in imports and protect domestic prices from external shocks. While in
FY26, the industry operating profit per tonne is expected to hold at
around $ 108, similar to last year, the industry’s earnings must
meaningfully improve from hereon to sustain large-scale investments.
Else, domestic mills could experience a significant spike in industry
leverage levels over the medium term, increasing their vulnerability to
external macroeconomic shocks.(~$ 60/tonne) over the past one month,
compressing the import parity discount to ~$ 23-25/tonne from previous
highs of ~$ 70-90/tonne, adds Jhunjhunwala. With this, he says, “the
industry can expect high resistance to further steel price increases.”

Domestic HRC prices have increased by ~Rs 5,000/tonne
“Aggressive
capacity additions (~15 mt commissioned in FY25, with 5 mt more by
FY26) have created a supply overhang, temporarily outpacing demand
growth of ~11-12 mt,” he says…
