Indian sector review: metals bear the brunt of the oil and yield shock

The three tracked sectors ended the week lower, with metals recording the heaviest decline. The common macro thread was a sharp rise in Brent crude, a weaker rupee and higher domestic bond yields. Traders linked the broad risk reduction to renewed Middle East tensions and the resulting concern over inflation, interest rates and imported costs.

The pressure was not uniform. Metals faced the combined effect of commodity-price volatility and doubts about Chinese demand. Auto companies had stronger underlying volume data, but the market weighed that against fuel and input-cost risks. Power demand and generation were firm, yet higher yields and tighter coal availability complicated the outlook for capital-intensive utilities.

Metals came under pressure as global commodity signals became less supportive despite some firm prices. Three-month copper had reached a record area during the week, while reports also pointed to lower copper imports by China in August and rising price sensitivity among Chinese buyers. China’s August unwrought-copper imports were 382,000 tonnes, down from 425,000 tonnes in July, while January-to-August imports were 6.7% below the year-earlier period. That combination left Indian producers exposed to a gap between high headline prices and uncertain near-term demand.

The selling was concentrated in the large counters. In Friday’s broad sell-off, Hindalco Industries fell 3.21%, JSW Steel declined 2.99% and Tata Steel lost 2.02%. The market also had to weigh higher crude and a weaker rupee against steel economics. Domestic hot-rolled coil prices were reported at Rs 62,000 a tonne for the week ended September 4, up 25% year-on-year, while rebar was at Rs 57,000 a tonne, up 20% year-on-year. No new Indian export-duty change was identified in the material available for the week. The coming week’s scheduled item with a direct company relevance is Hindustan Zinc’s analyst meeting at the Jefferies India Forum on September 16; no new metals-policy decision was identified as scheduled.

Auto shares weakened even though the operating data remained constructive. August retail sales were the strongest for that month, with total vehicle sales at 24,23,201 units and passenger-vehicle sales at 4,02,398 units, up 16.14% year-on-year. Electric-vehicle retail sales reached 2,98,448 units, up 52.9% year-on-year, lifting overall EV penetration to 12.3% from 9.5% a year earlier. Tata Motors led electric passenger-vehicle sales with 13,158 units, followed by Mahindra & Mahindra with 6,464 units.

The market instead focused on the margin risk from Brent, which rose 8.7% over the week to $104.61 a barrel, and on continuing raw-material pressure. Maruti Suzuki announced price increases of up to Rs 20,000 on selected models from September, while Tata Motors, Mahindra and Hyundai had also raised prices in stages during the year. In Friday’s session, Eicher Motors fell 2.17% and Maruti Suzuki declined 1.51%, while Tata Motors rose 0.20%; those moves illustrate the market’s preference for companies with stronger product or EV momentum, without removing the sector-wide cost concern. August sales were already reported, and no additional monthly volume print or company result was identified as scheduled for the coming week.

Power stocks weakened even as the underlying demand signal strengthened. During September 1 to 7, average maximum demand met was about 251.7 GW, 23% higher than in the corresponding period of 2025, while gross generation rose about 21% year-on-year to 41.1 TWh. Coal-fired generation supplied most of the incremental requirement, with coal generation rising about 27% year-on-year to 25.6 TWh. Renewable generation also rose, but its share of the mix was broadly maintained because demand expanded quickly and hydro generation was weaker.

The immediate input risk is coal availability, while the financing input is the India 10-year yield, which rose 6 basis points over the week to 7.0233%. Coal stocks at power plants fell from 28.64 million tonnes on September 1 to 26.7 million tonnes on September 6, and the number of plants with critical inventories rose from 45 to 58. In Friday’s trading, Power Grid fell 0.9%, NTPC declined 0.8% and Tata Power slipped 0.15%. The Central Electricity Authority’s draft proposal for new renewable projects to include co-located storage and grid-forming equipment also raises near-term execution and capital requirements, although it could support grid reliability over time. The scheduled event to watch is the G20 Energy Ministerial Meeting in Houston from September 14 to 16, where energy security, affordability and resilient supply chains are on the agenda.

Indian equities will reopen on Tuesday, September 15, after the September 14 Ganesh Chaturthi market holiday. The immediate cross-asset signals are therefore likely to remain important: Brent’s weekly rise has implications for inflation and transport costs, the rupee’s move raises the local cost of imported commodities, and the higher 10-year yield affects financing-sensitive companies.

For metals, the focus is whether Chinese buying and global steel margins stabilise, alongside Hindustan Zinc’s September 16 analyst meeting. For auto, the next evidence will be whether strong August demand can absorb price increases and higher fuel-related costs. For power, the G20 energy meeting and continuing coal-stock data will help frame the balance between near-term thermal dispatch and the longer-term investment required in renewable capacity, storage and transmission.
