Indian equity markets witnessed broad-based weakness across energy-linked and cyclical sectors on Thursday, as escalating geopolitical tensions in West Asia triggered a sharp spike in global crude prices and renewed uncertainty around supply chains.

Oil marketing companies (OMCs) were among the worst hit, reflecting immediate sensitivity to crude price movements. Brent crude surged nearly 7 percent to $107.29 per barrel, intensifying concerns around margin compression for downstream refiners and fuel retailers.

Shares of Hindustan Petroleum Corporation declined 3.55 percent, while Bharat Petroleum Corporation and Indian Oil Corporation also traded lower, reflecting investor concerns over the sustainability of marketing margins if crude remains elevated.

The pressure on OMCs stems from a structural challenge: while crude prices react instantly to geopolitical developments, retail fuel prices in India often adjust with a lag due to policy sensitivities. This creates a temporary mismatch that can compress refining and marketing spreads. If elevated crude levels persist, the sector may face earnings downgrades.

Beyond energy, the metals segment also came under selling pressure. Industrial metals such as copper, aluminium, and zinc declined globally after renewed geopolitical rhetoric from the United States signaled a potential escalation in the ongoing conflict involving Iran.

US President Donald Trump reiterated the possibility of targeting Iran’s civilian infrastructure, including power facilities, if negotiations fail. While he suggested that military action may be nearing completion, markets interpreted the statement as a signal of heightened risk rather than resolution.

This uncertainty weighed on global commodity sentiment, particularly for metals that are highly sensitive to both supply disruptions and global demand expectations.

Shares of APL Apollo Tubes and Hindustan Copper declined between 1 and 2 percent, tracking weakness in underlying metal prices.

The reaction in metals reflects a dual risk. On one hand, any disruption in West Asia can affect logistics and energy costs, indirectly impacting production. On the other, rising oil prices act as a tax on global growth, potentially dampening industrial demand—particularly from major economies.

Fertiliser stocks also saw mild declines, indicating a broader transmission of energy price shocks across input-heavy sectors. Shares of Rashtriya Chemicals and Fertilizers and Fertilisers and Chemicals Travancore slipped up to 1.5 percent.

The linkage here is direct: fertiliser production is energy-intensive, and higher natural gas and fuel costs can inflate production expenses. This raises concerns about subsidy burdens for the government and margin pressures for manufacturers if cost pass-through remains limited.

However, India’s diversified sourcing strategy for fertiliser imports provides a degree of insulation against immediate supply shocks. Unlike crude oil, where dependence on imports is significantly higher, fertiliser procurement has relatively broader geographic diversification, which may cushion extreme volatility.

From a macro perspective, the current development underscores the re-emergence of geopolitical risk as a key market driver. Elevated crude prices have implications beyond sectoral earnings—they feed directly into inflation expectations, currency stability, and fiscal calculations.

For India, sustained crude above the $100 mark could complicate the inflation trajectory and limit monetary policy flexibility. It may also widen the current account deficit, particularly if accompanied by currency depreciation.

Market participants are now closely tracking whether the current escalation remains contained or evolves into a prolonged disruption. The trajectory of crude prices will be a critical determinant of near-term sectoral performance.
