The market was dented by a defensive trade play and proposals from the government, which in turn triggered a massive sell‑off in the market. Along with the rebounding crude oil prices and US Treasuries hitting multi‑year highs, the sentiment was further dented by a defensive trade play and proposals from the government, which in turn triggered a massive sell‑off in the market. Equity investors continue to monitor the geopolitical sentiment and the talks between the United States and Iran, while keeping a close eye on energy prices, all of which are essential for an import‑heavy country like India.

India’s near‑term volatility index, Nifty India VIX, ended 6.9% higher this week as of Sept. 25, due to overall increased volatility in the market caused by several key factors which resulted in changes in prices and risk sentiment. One of the biggest factors which impacted the Indian stock market this week was the US Treasury yields rallying to a multi‑year high level of 5.23% on Friday due to the elevated geopolitical risk sentiment in the market, prompting equity investors to move towards safe‑haven assets. With frequent escalations in the West Asia region and no concrete signs of a potential peace deal between the United States and Iran, crude oil prices rebounded to above $107 per barrel (bbl) after declining below $100 per bbl earlier this week in the global market.

The benchmark Nifty Midcap 100 data showed that stocks like Patanjali Foods, Mankind Pharma, ICICI Lombard General Insurance Co., Phoenix Mills, and Steel Authority of India (SAIL) were the top five gainers this week.

Foreign institutional investors (FIIs) sold around ₹3,693.93 crore worth of capital market assets in a single day during the trading session on Friday, while domestic institutional investors purchased a total of ₹2,838.17 crore worth of capital market assets in a single day. As of the week ended September 25, foreign investors have remained net sellers in the Indian stock market due to higher risk sentiment for emerging market equities, the bounce back in global crude oil prices and elevated US Treasury yields. The domestic buying support added to the support, lifting the benchmark indices higher on Sept. 25, despite the 19‑year high of US Treasury yields amid the volatile geopolitical environment.
