U.S. and Indian equity markets fell sharply as Iran war fears, soaring oil and expensive AI projects sparked broad‑based selling.
The past two trading sessions have seen a sharp reversal in equity performance across the Atlantic and the sub-continent. In the United States, the S&P 500 slipped 1.2% while the technology-heavy Nasdaq fell 2.6%, driven by a mix of geopolitical nerves and concerns over the mounting cost of artificial intelligence infrastructure.
Meanwhile, Indian benchmarks such as the Nifty 50 and the S&P Sensex also closed lower, reflecting the impact of rising oil prices, heightened market volatility and sector-specific weakness.
United States equities falter on Iran war risk and AI cost worries
A wave of speculation that the United States and Israel are preparing a joint strike against Iran has unsettled investors. Reports suggest that potential targets include Iran’s energy facilities and nuclear sites, prompting a rally in Brent crude to just under $113 a barrel – its highest level since May – and U.S.
WTI climbing past $99 a barrel. The surge in energy prices lifted the oil-related risk premium, while risk-averse traders poured money into Treasuries, pushing the 10-year yield under the 5% threshold for the first time since September.
Tech giants lead the decline in the US
Within the equity decline, the technology sector bore the brunt. Meta Platforms disclosed that a shortage of computing capacity is hampering the rollout of its new Muse assistant abroad, and the firm signalled an additional $825 billion in AI-related contracts for the coming year. Though its earnings beat expectations when legal penalties were excluded, the guidance on future spending sparked a sell-off. Tesla also disappointed, trimming capital expenditures and merely confirming a modest expansion of its Cybercab fleet in Texas, which fell short of investor expectations for a more aggressive growth narrative. The sentiment was reinforced when Nvidia CEO Jensen Huang warned that financing the AI boom is becoming “scarce” as interest rates rise and existing commitments strain capital availability.
Indian benchmarks tumble as oil, volatility and sector pressure build
Across the Asian Pacific, Indian markets mirrored the global risk-off mood. The S&P Sensex ended down 0.17% at 73,123.83, while the Nifty 50 slipped 0.39% to 22,600, after briefly recovering from intra-day lows. The decline was not uniform; mid-cap and small-cap indexes suffered the steepest drops, with the Nifty Midcap 100 down 3.1% and the Nifty Smallcap 250 falling 3.6%. The Nifty Realty index plunged close to 4%, and defence-related stocks such as Nifty India Defence also lagged, highlighting the breadth of the sell-off.
Mid-cap and small-cap stocks bear the brunt in India
The heightened pressure on the smaller-cap segment reflects a broader shift toward large-cap safety, as investors seek liquidity and valuation comfort amid uncertain macro conditions. Banking shares, represented by the Nifty Bank, were down roughly 1.5% in the afternoon, while the Nifty IT index managed to stay relatively flat, showing some resilience among technology firms. The India VIX jumped more than 6% to 16.73, underscoring heightened expectations of volatility. Analysts point to the combination of elevated crude oil prices, firm U.S. Treasury yields, and lingering doubts about the sustainability of AI-driven capital spending as the primary catalysts behind the bearish stance.
Overall, the dual market dip underscores how intertwined geopolitical developments, commodity price swings, and the emerging reality of costly AI infrastructure investments can rapidly reshape investor sentiment. While U.S. indexes remain close to recent record highs, the lingering uncertainty may constrain further rallies, and the Indian market’s dependence on liquidity could see additional pressure if external risks persist.
