Dalal Street’s ‘fear gauge’ spikes 90% in CY26 as US-Iran war rattles equities; here’s what India VIX is signalling

When geopolitical shocks shake equity markets, investors instinctively look at benchmark indices. But the sharper signal often comes from elsewhere - the India VIX, Dalal Street’s own “fear gauge,” which captures how nervous traders expect markets to become in the coming weeks.

And in 2026, the VIX has told a story of rising anxiety, war-driven uncertainty, and relentless foreign capital outflows.

The India VIX has surged nearly 90% this year, climbing from 9.45 on January 2 to 17.91 on May 22, as investors grappled with escalating geopolitical tensions in the West Asia, surging crude oil prices, and growing macroeconomic policy uncertainty, including concerns around global trade tariffs, rising U.S. treasury yields, and currency volatility.

The benchmark Sensex and Nifty mirrored that nervousness. Both indices have declined nearly 10% on a year-to-date basis, while the January-March quarter witnessed intense selling pressure of around 15%. March alone saw a sharp 10% fall, the steepest monthly decline for Indian equities since the pandemic-driven turmoil of 2020.

For much of January, however, markets appeared relatively calm. The VIX largely traded between 9 and 11, levels usually associated with stable market conditions and investor confidence. February began similarly, although volatility gradually crept higher toward the 13–14 range as global macro concerns intensified.

US-Iran war intensifies volatility

By February 26, the India VIX stood at 13.06, already up about 38% from the start of the year. But the real shock came after the US-Iran war escalated, triggering fears of a broader regional war involving Israel and threatening global energy supply chains.

Between February 26 and March 30, the India VIX more than doubled, surging from 13.06 to 27.89, its highest level of the year. March became the defining month for volatility, with several sessions witnessing double-digit jumps in the VIX as traders scrambled to hedge portfolios and reduce risk exposure.

The spike in fear coincided with a sharp rise in crude oil prices, a weakening rupee nearing ₹92 per US dollar, and rising US Treasury yields, which made dollar assets more attractive relative to emerging markets like India.

FIIs responded with aggressive selling

So far in calendar year 2026, foreign institutional investors (FIIs) have remained net sellers in each of the first five months, pulling out more than ₹2.22 lakh crore from Indian equities. January saw outflows of ₹41,435 crore, followed by ₹6,641 crore in February. Selling accelerated dramatically in March, when FIIs offloaded a record ₹1.23 lakh crore worth of shares amid the U.S.-Israel-Iran conflict. The pace moderated somewhat in April, with outflows of ₹70,135 crore, while May selling up to May 23 stood at ₹30,374 crore.

Notably, cumulative FII selling in just five months of 2026 has already exceeded the total outflow of ₹1.66 lakh crore recorded in the whole of 2025.

Market experts believe volatility is unlikely to cool meaningfully in the near term.

“India VIX continues to hover near the 17.8 mark, indicating that market uncertainty remains elevated despite the recent recovery,” said Hariprasad K, Sebi-registered Research Analyst and Founder of Livelong Wealth.

He noted that elevated volatility has kept option premiums expensive, limiting aggressive option-selling strategies. “Unless markets witness a more sustained directional rally supported by improving global stability and cooling crude oil prices, volatility is likely to remain elevated,” he added.

Ajit Mishra, SVP–Research at Religare Broking, said investors should maintain a cautious and selective approach given geopolitical uncertainty, currency volatility, elevated crude prices, and uncertain foreign flows.

“Traders should avoid aggressive leverage and continue disciplined risk management practices. With volatility expected to remain elevated, a hedged and stock-specific approach will remain critical in the near term,” Mishra said.

He added that sectors such as energy, pharma, metals, capital markets, and defence continue to appear relatively attractive, while caution is warranted in IT stocks after the recent recovery.

Analysts at Bajaj Broking also highlighted that persistent geopolitical tensions, elevated crude oil prices, a weakening rupee, and rising bond yields have kept investor sentiment fragile. According to the brokerage, institutional flows are likely to remain highly sensitive to developments around US-Iran tensions and oil-price movements in the weeks ahead.

Even though the VIX has cooled from its March panic peak, Dalal Street’s fear gauge suggests investors remain far from comfortable. Beneath the surface, markets are still pricing in uncertainty, geopolitical fragility, and the risk of further shocks.
