Why Indian Stock Market Crashed Today Dec 8 2025: Sensex Down 800 Points, Nifty Below 26K on FII Selling, Weak Rupee at 90.17, and Fed Caution

Here’s what’s behind today’s sharp drop in the Indian stock market — and what it might mean for broader investors:

The market tumbled because heavy foreign-institutional selling (FII), a weakening rupee (around ₹90.17 per dollar), and mounting anxiety ahead of the Federal Reserve (Fed) policy meeting spooked investors. Once those three hit together, they triggered a broad sell-off, sending BSE Sensex tumbling ~800 points and Nifty 50 below 26,000.

Key takeaways

• Foreign investors pulled out big — over ₹11,800 crore in the first week of December — draining liquidity from Indian equities.
• The rupee cracked under pressure again, weakening past ₹90 per dollar — that amplifies foreign investors’ losses, making Indian equities less attractive.
• Global uncertainty — especially on what the Fed will do — ratcheted up fear. Many investors sold off ahead of the rate-cut decision, opting out of emerging-market risk.
• The downturn hit not just big names — mid-caps and small-caps also dropped, as profit-booking spread across sectors.

Why did the markets crash so hard today?

FII selling — exit of large foreign money

Foreign institutional investors (FIIs) pulled out nearly ₹11,820 crore in just the first week of December, citing concerns over currency volatility and global uncertainty.
With foreign buyers stepping back, price support vanished — triggering widespread selling. What starts in mid-cap or small-cap segments quickly reached heavyweight stocks, amplifying the fall.

Rupee weakness: ₹90+ = red flag for foreign investors

The rupee weakened to roughly ₹90.17–₹90.24 per U.S. dollar today.
That matters. A weak rupee erodes returns for overseas investors when they convert profits — so depreciation often sparks outflows.
Moreover, a weak currency raises costs for imports, pushes up inflation expectations, and increases hedging demand — a negative feedback loop for the equity market.

Eye on the Fed: global risk-off sentiment

All eyes are on the Fed’s upcoming meeting. Investors are uncertain whether the Fed will cut rates by 25 bps or hold firm.
Uncertainty on U.S. interest rates tends to spook emerging-market flows. India — seen as riskier — bore the brunt.
As foreign capital flows out, Indian equities come under pressure, regardless of domestic fundamentals.

Broader market mood: profit-booking + risk tightening

Markets had surged earlier in November on hopes of economic growth, corporate earnings, and rate-cut expectations from domestic central bank Reserve Bank of India (RBI). But after hitting 14-month highs, investors started locking in profits.
Now, with foreign money exiting and rupee weakening, profit-booking intensified — across large, mid, and small caps. The result: a sharp, broad-based retreat.

What this slump means — and what to watch next

Short-term risks rising

• Continued FII outflows could drag markets further.
• If the rupee weakens more (say toward ₹90.50–₹91.00), foreign investors might accelerate exits.
• Global cues — especially Fed’s stance and U.S. economic data — could deliver more volatility.

Dollar-denominated risk for foreign investors

Foreign investors are now facing losses not only from falling stock prices but also from currency depreciation. That double-hit may dampen appetite for equities for weeks.

Domestic opportunities — but caution warranted

Weak rupee may help exporters, boosting select export-oriented companies.
Long-term domestic investors might find bargains, but volatility remains high. Enter carefully.

Background: Why these patterns echo past crashes

History shows that sharp rupee depreciation + heavy FII selling often coincide with market crashes in India.

For example:

• Markets fell when currency hit weak levels and global uncertainty spiked.
• Sell-offs tended to accelerate when both large and small-cap stocks came under pressure.

Today’s slide reflects that same dynamic: global headwinds + domestic currency stress + heavy foreign outflows = perfect storm.

What investors should do now

• Don’t panic-sell. If you’re a long-term investor, volatile sessions of this kind often offer buying opportunities — especially in quality, export-oriented firms.
• Keep an eye on Fed cues & rupee moves. These external factors will likely continue deciding near-term direction.
• Consider hedging currency risk if holding large overseas portfolios or foreign-denominated debt.
• Prioritize diversification. Given the volatility, avoid putting all eggs in mid/small-caps or single sectors.
