Indian stock markets came under heavy selling pressure on Monday, August 31, as rising crude oil prices and renewed geopolitical tensions weakened investor sentiment. The Sensex fell around 500 points during the session, while the nifty50 slipped towards the crucial 24,000 mark.

A major concern for investors was the sharp rise in crude oil prices. Brent crude moved above $90 per barrel after renewed tensions between the United States and Iran raised fears of disruptions to oil supplies through the strategically important Strait of Hormuz. Higher oil prices are a concern for India because the country relies heavily on imported crude, potentially increasing inflation and pressure on the rupee.

Selling was visible across several sectors. The IT sector was among the major losers, with the Nifty IT index falling about 2%. Metal stocks also faced strong selling, with the Nifty Metal index declining more than 2%. Stocks including Hindustan Zinc, NALCO and Vedanta fell sharply.

Investors were also cautious because of rising US bond yields and growing expectations of a possible US Federal Reserve rate hike. The upcoming MSCI index reshuffling added another layer of uncertainty to trading.

Market participants are now closely watching crude oil prices, global geopolitical developments, the rupee and upcoming economic data. The combination of higher oil prices and global interest rate concerns could keep Indian markets volatile in the near term.
