Stock Market Crashes In India

COVID-19 Crash – March 2020

The COVID-19 crash stands out as one of the fastest and most severe market declines in modern history. As the COVID-19 pandemic spread across the globe, financial markets experienced unprecedented panic and volatility.

On 23rd March 2020, the Indian stock market witnessed one of its worst single-day crashes:

• The Sensex dropped by 3,935 points (13%), closing at 25,981.
• The Nifty fell by 1,135 points (13%), marking one of the steepest falls in a decade.
• The VIX (Volatility Index) soared to 71.56, reflecting extreme market fear.
• Of the 2,401 stocks regularly traded on the BSE, 2,036 stocks declined, while only 233 stocks advanced.

The downward spiral wasn’t limited to a single day. Within a week, the Sensex plunged from 42,273 to 28,288, erasing over ₹13.88 trillion in market value.

Global Impact

The panic selling wasn’t confined to Indian markets—it triggered a global meltdown. During the week of February 24, 2020, the Dow Jones and S&P 500 tumbled 11% and 12%, respectively, marking their biggest weekly declines since the financial crisis of 2008. The Dow suffered a historic 9.99% drop on March 12—its largest single-day decline since 1987—only to plunge even further by 12.9% on March 16. Global indices from Europe to Asia experienced similar sharp declines as uncertainty gripped financial markets worldwide.

Why Did the Market Crash?

The Indian government announced a nationwide lockdown starting from 23rd March, causing fears of an economic standstill.
Uncertainty about the duration and severity of the pandemic led to panic selling.
Large-cap stocks dropped over 15% in a single session.

Interestingly, the market rebounded quickly due to massive stimulus packages and liquidity support from the Reserve Bank of India (RBI). The Sensex recovered its pre-pandemic level within six months, one of the fastest recoveries in history.
 

Demonetisation and US Election Crash – November 2016

On 9th November 2016, the Indian market experienced a sharp decline following two major global events: the Indian government's surprise demonetisation announcement and Donald Trump's unexpected victory in the US presidential election.

• The Sensex fell by 1,688 points (6.12%) in a single day.
• The Nifty plunged over 540 points (6.33%).
• Crude oil prices dropped by 2.65%, adding to global market instability.

Why Did the Market Crash?

• The Indian government banned ₹500 and ₹1,000 notes to curb black money, causing uncertainty in the cash-dependent Indian economy.
• Donald Trump's early lead in the US election created uncertainty in global financial markets.
• Real estate stocks such as DLF, Godrej Properties, and Indiabulls Real Estate dropped by over 15%.

Yuan Devaluation and Brexit Crash – June 2015 to June 2016

The period between June 2015 and June 2016 saw a prolonged sell-off driven by multiple global factors, including China’s yuan devaluation and the UK’s Brexit vote.

• On 24th August 2015 (Black Monday), the Sensex dropped 5.94%, wiping out nearly ₹7 lakh crore.
• Between April 2015 and February 2016, the Sensex shed over 26%.

Why Did the Market Crash?

• China's economic slowdown and yuan devaluation triggered a global market sell-off.
• Falling oil prices added pressure on commodity-dependent economies.
• The Brexit vote in June 2016 created uncertainty about the future of the European Union, leading to a sharp rise in bond yields.
   

Global Financial Crisis – March 2008

The 2008 financial crisis is regarded as the worst global economic downturn since the Great Depression. It was triggered by the collapse of the US housing market and the subsequent failure of major financial institutions.

• On 17th March 2008, the Sensex fell by 950 points (6%).
• Just two weeks earlier, the index had dropped by 900 points.
• Between 2008 and 2009, the Indian market lost over 50% of its value.

Global Impact

• The crisis sent shockwaves through global financial markets.
• By September 2008, the Dow Jones had lost nearly 20% of its value.
• The Dow reached its lowest point on March 6, 2009—standing 54% below its previous peak in October 2007.
• It took nearly four years for the Dow to fully recover from the crash.
• Global markets collectively lost over $10 trillion in value within months as investor confidence evaporated.

What Exactly Went Wrong?

The roots of the crisis trace back to the late 1990s when the Federal National Mortgage Association (Fannie Mae) began making home loans more accessible to borrowers with low credit ratings, known as subprime borrowers. These borrowers were offered mortgages with higher interest rates and variable payment schedules to reflect their elevated risk profiles.

This surge in subprime mortgage lending fueled a housing boom, driving up home prices and encouraging further borrowing. Financial institutions also capitalized on the housing boom by bundling these risky mortgages into complex financial products (mortgage-backed securities) and selling them to investors.

The cracks began to show in March 2007 when Bear Stearns, a major investment bank, could not cover its losses linked to subprime mortgages. While the market initially brushed this off—climbing to a peak of 14,164 points in October 2007—the situation spiraled out of control by September 2008 when Lehman Brothers filed for bankruptcy. Panic selling followed, and financial markets around the world plunged into turmoil.

Why Did the Market Crash?

• Banks offered risky subprime mortgages to borrowers with poor credit.
• The collapse of Lehman Brothers triggered a financial contagion.
• Excessive debt and over-leveraging in the housing market created a fragile financial system.
• Global markets lost over $10 trillion in value within months.
   

Dot-Com Bubble Burst – 1999–2000

During the late 1990s, internet-based stocks experienced an unprecedented boom. The Nasdaq Composite Index surged from 1,000 points in 1995 to over 5,000 points in early 2000. However, the bubble burst when overvalued tech stocks crashed.

The primary cause of the crash was the overvaluation of internet stocks—many dot-com companies had little to no revenue but were still attracting heavy investment. Investors speculated that these companies would eventually dominate the market, driving up valuations to unsustainable levels. The bubble finally burst when the Federal Reserve Board tightened its monetary policy, raising interest rates and constraining the flow of capital.

• The Nasdaq peaked at 5,048.62 on March 10, 2000 before plummeting by 76.81% to 1,139.90 by October 2002.

Why Did the Market Crash?

• Overvaluation of internet stocks with little to no revenue.
• Speculative investing and easy credit fueled the bubble.
• The Federal Reserve’s interest rate hikes reduced liquidity.
   

Harshad Mehta Scam – April 1992

On 29th April 1992, the Sensex crashed by 570 points (12.77%) following the exposure of the Harshad Mehta scam. Harshad Mehta, known as the Big Bull of the Indian stock market, orchestrated a massive market manipulation scheme that sent shockwaves through the financial system.

Mehta would buy large volumes of shares in specific companies, driving up demand and artificially inflating prices. For instance, he invested in ACC Limited, causing its share price to skyrocket from ₹200 to ₹9,000 within just 2–3 months. To finance these trades, Mehta exploited loopholes in the banking system, siphoning off over ₹1,000 crore from banks to fuel his market activities.

The scam unraveled when a journalist, Sucheta Dalal, exposed the fraudulent practices in April 1992. The shock triggered a prolonged bear market that lasted for nearly two years as investor confidence eroded.

• The market lost nearly 40% of its combined value in the following months and dropped by around 2,000 points to levels of 2,500.

Why Did the Market Crash?

• Fraudulent banking practices were used to inflate stock prices.
• Loss of investor confidence led to panic selling.
   

Black Monday – October 1987

On October 19, 1987, the Dow Jones Industrial Average fell by 22%—the largest single-day decline in stock market history, wiping out over $500 billion in market value. In the weeks leading up to the crash, the U.S. market had been on an extended bull run, with the Dow Jones climbing over 40% in the first nine months of the year. 

However, rising interest rates and growing geopolitical tensions created unease among investors. The breaking point came when automated program trading, designed to limit losses, triggered a wave of forced selling. Panic spread to other markets, causing steep declines in London, Hong Kong, and Tokyo.
 

The 1982 Dhirubhai Ambani Incident

In 1982, Reliance Industries found itself at the center of an intense battle in the Indian stock market. A powerful bear cartel from Kolkata initiated a large short-selling operation involving nearly 1.1 million Reliance shares. The goal was to drive down the stock price and profit from the decline. As a result, Reliance shares fell from ₹131 to ₹121, creating panic among investors. However, Dhirubhai Ambani was quick to respond. He mobilized his supporters, known as the "Friends of Reliance," who started buying back the shares aggressively to counteract the bearish attack.

The situation escalated rapidly, forcing the Bombay Stock Exchange (BSE) to intervene. Ambani took a bold stand, declaring that the market would not reopen until all outstanding deals were settled. His firm stance resulted in an unprecedented three-day market shutdown, a rare event in Indian market history. This strategic move not only stabilized Reliance’s stock price but also protected small investors from major losses. The incident exposed the vulnerabilities of India’s stock market and highlighted the growing influence of corporate giants in shaping market trends.

What Happened?

Bear operators short-sold Reliance shares to drive down the price.
Ambani’s supporters intervened, causing a price surge.

Impact:

Reliance’s stock price surged despite the attack.
The incident solidified Dhirubhai Ambani’s dominance in Indian markets.
 

The Great Depression – 1929 Stock Market Crash

The 1929 crash remains the worst in history, wiping out billions in wealth and plunging the world into a decade-long depression.

• On Black Monday and Black Tuesday (October 28–29), the Dow lost over 25% of its value.
• By mid-1932, the Dow had fallen 89% from its peak.

Why Did the Market Crash?

• Excessive leverage and speculative investing.
• Weak banking regulations and overvaluation of stocks.
   

Lessons from History

Stock market crashes often follow periods of market euphoria and excessive risk-taking. While they cause significant short-term pain, history shows that markets eventually recover. Investors who remain patient and diversify their portfolios tend to weather market downturns better than those who panic. Understanding the causes and patterns of the worst stock market crashes can help investors navigate future volatility with greater confidence.
