Indian equities are witnessing heightened volatility as a combination of surging crude oil prices, elevated US bond yields, a weaker rupee and geopolitical uncertainty weighs on investor sentiment.
The sell-off intensified on Monday, September 28, when the BSE Sensex dropped 1,124.02 points, or 1.52%, to close at 72,771.72. The Nifty 50 fell 360.25 points, or 1.56%, to 22,780.25. The decline erased nearly ₹8 lakh crore in market value, taking the total market capitalisation of BSE-listed companies to around ₹474 lakh crore.
1. Crude oil crosses $107
Oil has emerged as one of the biggest concerns for Indian markets. Brent crude moved above $107 a barrel, while WTI crude traded close to $94. Higher oil prices are particularly important for India because they can increase the import bill, add inflationary pressure and put pressure on the rupee and government finances.
2. US bond yields remain elevated
The US 10-year Treasury yield moved above 5.2%, reaching levels not seen in many years. Higher US yields can make dollar-denominated assets relatively more attractive and add pressure to emerging-market equities.
3. Rupee falls past ₹96
The Indian rupee also came under pressure, slipping beyond the ₹96-per-dollar level. Rising crude prices, a stronger dollar and elevated US yields have added to currency-market concerns.
4. Geopolitical uncertainty
Markets are closely tracking developments involving the US and Iran, particularly concerns surrounding the Strait of Hormuz and potential disruption to global oil supplies. The uncertainty has contributed to the sharp rise in crude prices and broader risk aversion.
5. Foreign investor selling
Foreign portfolio investors have also remained a source of pressure. ET reported that foreign investors sold ₹3,694 crore of Indian equities on Friday, with cumulative equity outflows through exchanges reaching ₹25,682 crore during September at that point.
6. Global market weakness
The selling has not been confined to India. Asian markets also came under pressure amid the oil-price surge, with South Korea's Kospi and China's Shanghai Composite among the major indices declining.
The market decline can cause the value of equity mutual fund portfolios to fall temporarily because their underlying stocks are marked to current market prices. However, a SIP is a periodic investment strategy, so each instalment buys units at the prevailing NAV. During market declines, the same investment amount can purchase more units, although this does not guarantee returns or protect against losses.
For investors, the key factors to monitor are crude oil prices, US Treasury yields, the rupee-dollar exchange rate, foreign fund flows and geopolitical developments. The September 29 session also showed continued volatility, with the Nifty moving sharply during intraday trade as investors assessed these factors.
The immediate market narrative therefore remains centred on whether the pressure from oil and global macroeconomic conditions persists, rather than on the movement of any single stock or sector.
