Sensex and Nifty opened lower on Tuesday, 25 August, as investors weighed escalating geopolitical tensions in the Middle East and their potential spillover on crude oil supplies. Caution also gripped the market ahead of the monthly expiry of Nifty 50 derivatives contracts, amplifying intraday volatility.
Early Session Losses
The BSE Sensex fell as much as 223 points, or 0.28%, to touch an intraday low of 77,146 in morning trade. The Nifty 50 slid 90 points, or 0.37%, to 24,128. The selling was broad-based, with most sectoral indices trading in negative territory.
Sectoral Movers and Laggards
Nifty Media, PSU Bank, and Nifty Chemicals were among the few bright spots, each gaining up to 0.6%. On the downside, Nifty Metal was the worst performer, declining 0.48%, followed by Nifty Oil and Gas, which fell 0.4%. Nifty IT dropped 0.37%, while Nifty Auto and Nifty Realty each slipped 0.32%. Shares in FMCG, healthcare, consumer durables, and pharma also traded lower.
Crude Oil and Iran Sanctions in Focus
Crude oil prices steadied on Tuesday after a sharp decline in the previous session, as markets assessed the impact of tighter US sanctions on Iran and the threat of secondary sanctions on countries trading with Tehran. Analysts warn that elevated oil prices could constrain any sustained equity rally in the near term, given India's sensitivity to import costs. This marks the latest instance of global energy uncertainty feeding directly into domestic market sentiment.
Analyst Outlook and Near-Term Range
Analysts expect the broader market to remain range-bound, with buying interest emerging at lower levels and selling pressure at higher levels. The near-term range for the Nifty is pegged at 24,100–24,500. According to market analysts, 'Despite slipping through the day, yesterday's pull back in the closing hour encourages us to look for a rise to 24,400 today. Alternatively, inability to float above 24,200 or slippage past 24,144 will expose 23,575, with last support seen at 24,060.'
Institutional Activity and Midcap Interest
In the previous session on Monday, foreign institutional investors turned net buyers, purchasing equities worth ₹1,181 crore. Domestic institutional investors extended their buying streak for the 10th consecutive session, investing ₹2,493 crore. Notably, market activity has remained concentrated in the midcap and smallcap segments, where positive corporate news flow has continued to attract buying interest despite broader valuation concerns.
With the monthly derivatives expiry adding a layer of uncertainty, traders are expected to stay cautious through the session. The direction of crude oil prices and any fresh geopolitical developments out of the Middle East will remain the key near-term triggers for Indian equities.
Point of View
So every spike in Middle East risk is a direct hit to the current account and corporate margins — particularly in autos, FMCG, and logistics. The Iran sanctions angle is underappreciated: secondary sanctions could force Indian refiners, who have leaned heavily on discounted Iranian and Russian crude, into a costly pivot. Meanwhile, the FII buying in midcaps despite valuation concerns signals liquidity-chasing rather than conviction — a fragile foundation if oil sustains above current levels.
