21 September 2026 (Navroze Bureau) : Indian stock markets are set for a cautious start on September 21, with investors tracking developments in the Middle East conflict, crude oil prices, global bond yields and foreign fund flows.
The GIFT Nifty was trading around 23,338.5, indicating a discount of nearly 40 points from the previous Nifty futures close and pointing to a potentially subdued opening for the benchmark indices.
Here are five key factors likely to influence market sentiment during Monday’s session.
1. GIFT Nifty Signals Cautious Opening
GIFT Nifty remained in focus ahead of the Indian market opening. Its trading level around 23,338.5 suggested that investors were preparing for a cautious session.
The indicator reflects sentiment in the offshore derivatives market and is closely watched for clues about the opening direction of the Nifty 50.
2. Middle East Conflict Remains a Major Risk
Developments in the US-Iran conflict remain one of the biggest variables for global markets.
Any renewed escalation could disrupt energy supplies, push crude prices higher and increase concerns about inflation. Investors are also watching diplomatic efforts and developments involving oil shipments through the region.
For Indian equities, prolonged geopolitical uncertainty could weigh on risk appetite, particularly if it causes another sharp rise in crude prices.
3. Crude Oil Prices Stay Above $100
Crude remains a major concern for India because the country imports a large share of its oil requirements.
Brent crude was trading around $104 a barrel in early market indications, although prices have recently eased as Saudi Arabian shipments recover. Other reports put Brent around $101.70 after another decline.
Lower oil prices can provide some relief to India’s inflation outlook and reduce pressure on the country’s import bill. However, crude remains elevated compared with levels seen before the conflict.
4. US Treasury Yields Near 5%
US bond yields are another important factor for Indian equities.
The benchmark 10-year US Treasury yield moved above 5%, raising concerns about global borrowing costs and the attractiveness of US assets relative to emerging-market equities.
Higher US yields can also influence foreign portfolio flows into India and put pressure on emerging-market currencies, including the rupee.
5. Asian Markets and Global Sentiment
Asian markets opened mixed as investors assessed the Middle East conflict and movements in oil prices.
South Korea’s Kospi gained at the open, while Australia’s S&P/ASX 200 declined. Japanese markets remained closed for a holiday.
Wall Street had ended a volatile week with mixed performance, while investors continued to monitor technology stocks, Treasury yields and commodity prices.
Indian Market Faces Multiple Headwinds
The Indian benchmarks are also coming into the session after recording their sixth consecutive weekly decline, according to Reuters.
At around 9:23 a.m. IST on September 21, the Nifty 50 was down 0.07% at 23,330.2, while the Sensex was up 0.32% at 74,535.18. The market was also dealing with liquidity concerns linked to the large NSE IPO, which was scheduled to close that day.
What Investors Will Watch
Apart from crude and geopolitical developments, traders are likely to monitor the rupee, FII and DII activity, bond yields and global market cues.
A sustained decline in oil prices could offer some relief to Indian equities, while another escalation in the Middle East could quickly reverse that trend.
For now, the market backdrop remains sensitive to external developments, making crude oil and geopolitical headlines particularly important for the direction of the Sensex and Nifty 50.
