Indian shares have had a rough few weeks. On 8 October 2026 the BSE Sensex fell about 1,045 points (1.44%) to 71,593, and the Nifty 50 dropped 371 points (1.64%). That came after a 1,124-point Sensex fall on 28 September that left the index at its lowest close since March. If you are searching "why is the stock market falling today", the short answer is that four pressures are hitting at the same time.
1. Crude oil is above $100 a barrel
India imports most of the oil it uses, so expensive crude hurts in several ways at once. Brent crude rose about 5% to $105.30 on 8 October, and it has spent much of the year well above the ~$60 level seen in February because of the conflict in West Asia and disruption around the Strait of Hormuz.
- Higher import bill: India needs more dollars to buy the same oil, which weakens the rupee.
- Inflation risk: fuel feeds into transport and manufacturing costs, which squeezes company margins.
- Sector damage: oil marketing companies, paints, aviation, tyres and chemicals are especially sensitive.
2. Foreign investors (FPIs) keep selling
Foreign portfolio investors pulled about ₹44,166 crore out of Indian equities in the first part of October alone, according to NSDL data reported on 11 October. Estimates put total 2026 outflows at roughly ₹3 lakh crore, far more than all of last year. When large global funds sell, prices fall across heavyweight stocks such as banks and IT, and that drags the indices down.
Why are they selling? Higher US bond yields make safer US assets more attractive, a falling rupee cuts dollar returns, and Indian valuations are still higher than many other emerging markets.
3. The rupee is near record lows
The rupee closed near 96.78 per US dollar on 7 October, just a few paise from its all-time low of about 96.96. A weak rupee raises the cost of imports and makes foreign investors' returns smaller in dollar terms, which can trigger more selling, a loop that is hard to break while oil stays high.
4. Interest rates are going up
The Reserve Bank of India raised the repo rate by 25 basis points to 5.50% and moved its stance to "calibrated tightening" to fight imported inflation and support the rupee. Higher rates make borrowing costlier for companies and households and tend to weigh on rate-sensitive sectors such as banks, NBFCs, real estate and autos.
What the fall looks like across the market
| Factor | Latest reading | Why it matters |
|---|
| Brent crude | ~$105 / barrel (8 Oct) | Import bill, inflation, margins |
| FPI equity flows | −₹44,166 cr in October (to 11 Oct) | Selling in index heavyweights |
| Rupee | ~96.8 per $ (7 Oct) | Costlier imports, lower dollar returns |
| RBI repo rate | 5.50% after a 25 bp hike | Costlier loans, pressure on valuations |
| India VIX | Up ~10% on 8 Oct | Higher fear, bigger daily swings |
The selling has not been limited to large caps. Mid-cap and small-cap stocks also fell, and these usually drop harder in a risk-off market.
Is there any good news?
Not every sector is falling. IT stocks rallied strongly on 13 October after HCLTech's strong Q2 results, and the Nifty gained about 1.6% that day as fear eased. A weak rupee also helps exporters such as IT and pharma, because they earn in dollars.
What should investors do now?
- Don't panic-sell good businesses. Market falls driven by global factors often reverse when those factors ease.
- Keep your SIPs running. Falling markets let SIPs buy more units at lower prices.
- Check your asset allocation. If a fall makes you lose sleep, you may hold more equity than suits you.
- Avoid leverage. Borrowed money and F&O positions can turn a temporary dip into a permanent loss.
