Stock market crashes in India
Since the beginning of the Bombay stock exchange, stock markets in India, particularly the Bombay Stock Exchange and National Stock Exchange of India have seen a number of booms as well as crashes. This page lists these crashes and sharp falls in the two primary Indian stock markets, namely the BSE and NSE. Financial Times terms a double-digit percentage fall in the stock markets over five minutes as a crash, while Jayadev et al. describe a stock market crash in India as a "fall in the NIFTY of more than 10% within a span of 20 days" or "difference of more than 10% between the high on a day and the low on the next trading day" or "decline in the NIFTY of more than 9% within a span of 5 days". As per the latter definition, the Nifty experienced 15 crashes during the period 2000 to 2008 with a number of them having occurred in the months of January, May and June 2008. The crash of 1865
As per the Business Standard, India experienced its first stock market crash in 1865. Although the Bombay stock exchange had not yet been formed, Gujarati and Parsi traders often traded shares mutually at the junction of Rampart row and Meadows Street. In the preceding years, speculation about the results of the American Civil War had led to irrational increases of stocks of new Indian companies. Shares of the Back Bay reclamation (face value Rs. 5,000) touched Rs. 50,000 and those of Bank of Baroda (face value Rs.50000000) touched Rs. 29,00,050. Money made from cotton was pumped into the stock market driving prices of stocks higher. Banks loaned money to speculators further fueling the bull run and wealthy merchants like Premchand Roychand dispensed advice that led to ordinary people placing their bets on shares. On 16 November 1864, the governor warned civil servants not to participate in the current frenzy. New companies were floated with new share issues publicized in the newspapers. Forward contracts further promoted speculative purchases. However, the market crashed in May 1865 when the civil war ended, causing cotton prices to fall. Shares of the Backbay reclamation fell by 96% to under Rs. 2,00,000 and a number of merchants including Behramji Hormuzjee Cama went bankrupt. The crash not only led to a dwindling of the financial fortunes of many, it also led to a decrease of the city's population by 21% due to the closing down of many enterprises. On 1 July 1865,  when hundreds of "time bargains" had matured (as the future contracts were then known), buyers and sellers alike defaulted leading to the burst of the bubble. A share of Bank of Bombay which had touched Rs 2,850 at the peak of the market slumped to just Rs 87 in the aftermath of the bust. Crash of 1982 
In 1982, the bear cartel of Bengal started short selling shares targeted primarily of Reliance. Stocks around 110,0000 was short sold. The value of shares decreased significantly. The BSE was shut down for three consecutive days. Crash of 1991
After economic liberalization in India in 1991, the stock market saw a number of cycles of booms and busts, some related to scams such as those engineered by players such as Harshad Mehta and Ketan Parekh, some due to global events and a few due to circular trading, rigging of prices and the irrational exuberance of investors leading to bubbles that finally burst. Crash of 1992
On 28 April 1992, the BSE experienced a fall of 12.77% - due to the Harshad Mehta Scam. UPA 1 election crash of 2004
On 17 May 2004, the BSE fell 15.52% - its largest fall in history (in terms of percentage). Crash of 2006

In 2007, there were five sharp falls in the stock markets. 2 April 2007: The Sensex fell by 617 points to 12,455 though during the course of the day, it fell further.

 on 21 Jan 2008, the BSE fell by 1,408 points to 17,605 leading to one of the largest erosions in investor wealth. The BSE stopped trading for a while at 2:30 pm due to a technical snag although its circuit filter allows swings of up to 15% before stopping trading for an hour. Referred to in the media as "Black Monday", the fall was blamed by analysts at HSBC mutual fund and JP Morgan on a large variety of reasons including change in the global investment climate, fears of  United States' economy going into a recession, FIIs and foreign hedge funds selling in order to reallocate their funds from risky emerging markets to stable developed markets, a cut in US interest rates, global bourses (often referred to as event related volatility), volatility in commodities markets, a combination of global and local factors ("...other emerging markets were down nearly 20% so India is playing catch-up..."), huge build-ups in derivatives positions leading to margin calls and that many IPOs had sucked out liquidity from the primary market into the secondary market. HSBC mutual funds analysts predicted further falls in the stock market, and the analysts at JP Morgan were of the opinion that market would fall a further 10-15%. On the next day on 22 January 2008, the Sensex again fell by 875 points to 16,729. Jan 22, 2008: The Sensex saw its biggest intra-day fall on Tuesday when it hit a low of 15,332, down 2,273 points. However, it recovered losses and closed at a loss of 875 points at 16,730. The Nifty closed at 4,899 at a loss of 310 points. Trading was suspended for one hour at the Bombay Stock Exchange after the benchmark Sensex crashed to a low of 15,576.30 within minutes of opening, crossing the circuit limit of 10 per cent. On 11 Feb 2008, the Sensex fell by a further 834 points to 16,630. On 3 March 2008, the Sensex fell by 900 points to settle at 16,677.

On 26 November 2008, the Sensex continue to fall, in the bargain (as per the financial newspaper Livemint) "...dashing middle class dreams". Analysts at Livemint and Ajmera associates, Anagram capital and Ace financial services ascribed a number of reasons for this, ranging from large sales by foreign institutional investors (FII), withdrawal of money by the insurance sector. They all felt that the Sensex could rise by at the most 20-30% in 2009, from its them level of 9000 points. Crash of 2009
On 6 July 2009, the Sensex fell by 869 points to 14,043. Crashes 2015 
 On 6 January 2015, the Sensex fell by 854 points to 26,987. On 24 August 2015, the BSE Sensex crashed by 1,624 points and the NSE fell by 490 points. Finally the indices closed at 25,741 points and the Nifty to 7,809 points. The reason given for this crash was given as a ripple effect due to fears over a slowdown in China, as the Yuan had been devalued two weeks ago leading to a fall in the currency rates of other currencies and the rapid selling of stocks in China and India. The Shanghai stock exchange too fell by 8.5%. A variety of other reasons too were given for this fall by analysts including disappointing earnings in the first quarter for many Indian companies, somber commentaries by their management leading to doubts regarding their recovery and a below average monsoon for that year. Crashes of 2016
The stock markets in India continued to fall in 2016. By 16 February 2016, the BSE had seen a fall of 26% over the past eleven months, losing 1607 points in four consecutive days of February. The reasons given for this included NPAs of Indian banks, "global weaknesses" and "global factors". In the four months from November 2015 to February 2016, FIIs were reported to have sold equities worth Rs 17,318 crore as, in the opinion of analysts, concerns grew over growth in China and as crude oil prices tumbled below $30 per barrel

On 9 November 2016, crashed by 1689 points, believed by analysts to be due to the crackdown on black money by the Indian government, resulting in frantic selling. The Sensex nosedived by 6% to 26,902 and the Nifty dropped by 541 points to 8002. These were said to be due to the demonetization drive by the Modi government. The Hindu was of the opinion that the weakening rupee and the US presidential election too had some bearing on the behavior of investors. The fall was concurrent with falls in other Asian stock markets including the Hang Seng, Nikkei and the Shanghai Composite. The S&P had also fallen by 4.45%. Crashes of 2018
 Although not classified as a crash, the BSE and NSE fell sharply on 2 and 5 February 2018, sparked by the comments of the Finance minister's proposal in the budget speech to introduce a 10% long term capital gains tax (LTCG) on equity shares sold after 12 months.

The fall was also weighed by the global breakdown amid coronavirus pandemic centered in China. On 28 February 2020, Sensex lost 1448 points and Nifty fell by 432 points due to growing global tension caused by COVID-19 pandemic, which W.H.O said has a pandemic potential.
