Global Tensions Spike: Indian Markets Brace for Volatility as US-Iran Conflict Threatens Oil Supply​

Indian equity markets reacted with cautiousness after the renewed US-Iran conflict resurfaced, shattering the investor sentiment that had built up following the collapse of a fragile ceasefire. The rise in geopolitical risk has immediately shifted focus back to crude oil prices and global supply chain stability. While benchmark indices showed minor dips on subsequent trading days, the market mood is decidedly wary, reflecting concerns over energy supplies and potential inflation spikes.

Market Reversal: From Rallies to Renewed Caution​

The renewed tensions have halted a rally that had been gathering momentum since the ceasefire was first established in early April. Between early April and July 10, the Sensex and Nifty saw gains of around 8 percent each. Broader market segments performed even better during this bullish period; the BSE MidCap 150 Index and BSE SmallCap 250 Index advanced a robust 20 percent and 23 percent respectively.

However, the post-ceasefire euphoria has not lasted. Since July 10, sentiment has turned noticeably cautious across the board. The Sensex and Nifty have slipped approximately 0.5 percent each in subsequent sessions. Concurrently, the BSE MidCap 150 Index and BSE SmallCap 250 Index declined around 0.7 percent each.

Geopolitical Risk and Crude Oil Concerns​

The market's attention is intensely focused on the Strait of Hormuz, a crucial shipping route that facilitates nearly one-fifth of global oil and gas supplies. Investors are currently assessing whether this latest disruption will prove temporary or if it is evolving into a prolonged supply shock capable of driving crude prices higher.

This instability has been reflected in commodity movements. Brent crude oil has climbed 12 percent, while the India VIX index has risen by 13 percent since the conflict reignited. The concern remains that a sustained rise in imported inflation could delay expectations of monetary easing by the Reserve Bank of India (RBI).

Analyst View: Key Risk Thresholds and Economic Impact​

SBI Securities' Sunny Agrawal stated that the primary worry is the impact on energy prices. Although crude has risen 8-10 percent, it remains below $85 a barrel. He noted that companies have largely factored in higher oil costs through strategic measures like price hikes, product mix adjustments, and cost optimisation.

However, Agrawal issued a strong warning: if Brent climbs above the $100-$120 a barrel range, markets could transition into a broader risk-off phase. This scenario would put pressure on both the rupee and bond yields, reviving inflation concerns and potentially widening fiscal and current account deficits, triggering foreign institutional selling.

Sectoral Sensitivity: Who Faces Pressure?​

The immediate impact of this uncertainty is expected to be elevated volatility rather than a sustained shift in India's long-term growth trajectory, according to analysts. Similar geopolitical flares over the past year have typically resulted in short-term profit booking rather than fundamental market change.

Aamir Makda of Choice Broking highlighted that aviation, paints, automobiles, and oil marketing companies are likely to face pressure due to higher crude prices. Conversely, oil exploration firms and defensive sectors like IT and pharma could benefit from the trend.

Agrawal also noted that aluminium prices have begun firming up amid renewed supply disruption concerns. Furthermore, companies with significant exposure to the Middle East, including structural steel and tube pipe manufacturers and Larsen & Toubro, could face pressure if the conflict escalates further. Cranthi Baithini added that while crude oil remains the biggest variable, better-than-expected monsoon progress and the ongoing earnings season remain supportive factors for equities.
