Why the Stock Market Crashed Today: Top 5 Reasons for the February 12, 2026 Sell-off
By Kaushik
Published on 12, February 2026.
If you look at your portfolio today, you likely saw a sea of red. On Thursday, February 12, 2026, the Indian stock market snapped its four-day winning streak with a significant correction. The BSE Sensex tumbled over 550 points to settle at 83,674, while the NSE Nifty 50 slipped below the 25,850 mark, closing at 25,807.
Investors lost approximately ₹3 lakh crore in a single session. But what exactly triggered this sudden “nosedive” correction? Here is a breakdown of the primary factors that spooked Dalal Street today.
1. The “Anthropic Shock” and IT Sector Meltdown
The biggest culprit behind today’s crash was the Information Technology (IT) sector. The Nifty IT index plummeted by a staggering 5.5%, marking one of its worst intraday sessions this year.
The trigger? News from the US-based AI startup Anthropic. The company unveiled a new AI tool specifically designed for corporate legal and compliance teams. This tool can automate complex tasks like contract analysis and legal brief preparation—tasks that have traditionally been high-volume revenue generators for Indian IT giants. This “AI disruption” anxiety led to heavy selling in heavyweights like Infosys, TCS, and Tech Mahindra, which fell between 4% and 6%.
2. Strong US Jobs Data: The “Rate Cut” Dilemma
Ironically, good news from the United States turned into bad news for global markets. New data showed that US non-farm payrolls added 130,000 jobs in January, significantly higher than expectations. While a strong economy is usually positive, it signaled to investors that the US Federal Reserve is unlikely to cut interest rates anytime soon.
Higher interest rates for a longer period generally lead to a “risk-off” sentiment, prompting foreign investors to pull money out of emerging markets like India and move it back to US bonds.
3. Weak Cues from Wall Street
Indian markets often mirror the performance of US tech indices. Overnight, the Nasdaq Composite and S&P 500 ended in negative territory, largely driven by a 6.5% crash in IBM shares. This negative sentiment spilled over into the Asian opening bell, giving Indian bears the upper hand from the start of the session.
4. Rising Crude Oil Prices & Geopolitical Tensions
Energy costs play a massive role in India’s inflation dynamics. Today, Brent crude oil prices edged higher toward $70 per barrel. Additionally, lingering geopolitical tensions between the US and Iran have kept investors on edge. Analysts suggest that these “macro-headwinds” make it difficult for the market to sustain higher valuation levels, leading to cautious profit-booking.
5. Technical Profit Booking
After a strong rally in early February, many traders decided to “take money off the table.” Having hit psychological resistance levels near 26,000 (Nifty) and 84,000 (Sensex), the market was ripe for a healthy correction.
”The fall is largely sector-specific pressure from the IT pack. While sectors like Finance and Defense tried to provide support, it wasn’t enough to offset the heavy drag from technology,” says market strategist Dr. V.K. Vijayakumar.
Summary Table: Market Snapshot (Feb 12, 2026)
Index Closing Level Change (%) Key Laggard
BSE Sensex 83,674.92 -0.66% Tech Mahindra (-6.4%)
NSE Nifty 50 25,807.20 -0.57% Infosys (-5.9%)
Nifty IT 33,160.00 -5.51% TCS (-5.7%)
What Should Investors Do?
While today’s crash feels painful, many analysts view it as a structural correction rather than a long-term bear market. The Indian economy remains fundamentally strong, and foreign institutional investors (FIIs) have recently been net buyers. For long-term investors, such dips often provide an entry point into high-quality stocks at better valuations.
