What Happens When the Market Crashes?
A market crash is one of the most frightening things a new investor can experience. Understanding what actually happens — and why — makes it far less scary and helps you make better decisions.
Key takeaways
What is a market crash?
A market crash is a sudden, sharp fall in stock prices across the board — usually 10% or more in a very short period. It is different from a slow bear market. A crash happens fast, often within days or weeks, triggered by a specific event or a sudden shift in investor sentiment. The COVID crash in March 2020 saw the Nifty fall nearly 40% in just 30 days.
What causes a crash?
Crashes can be triggered by many things. A global health crisis like COVID-19. A financial system failure like the Lehman Brothers collapse in 2008. A sudden spike in inflation or interest rates. A geopolitical shock like a war. Sometimes markets have simply risen too fast for too long and a correction was inevitable — one piece of bad news is enough to start a chain reaction of panic selling.
What actually happens during a crash?
Fear spreads quickly. Investors who borrowed money to invest are forced to sell to repay loans — this adds more selling pressure. Mutual funds sometimes face large redemption requests and have to sell their holdings to pay investors back. Algorithmic trading systems trigger automatic sell orders when prices fall below certain levels. All of this accelerates the fall and makes it feel worse than the underlying reality.
Should you sell when the market crashes?
For most long-term investors, the answer is no. When you sell during a crash, you lock in your losses permanently. Markets have recovered from every single crash in history. The Nifty 50 fell 38% during COVID in March 2020 — and recovered fully within 6 months, going on to hit all-time highs by early 2021. Selling in panic means you miss the recovery. And the recovery often happens fast — sometimes in a matter of weeks.
What should you actually do during a crash?
If you have a SIP running, keep it running. Falling markets mean you are buying more units at lower prices — this is rupee cost averaging working in your favour. Do not check your portfolio every hour. The people who come out best after crashes are the ones who stayed invested and stayed calm. Every generation of investors faces at least one major crash — 2000, 2008, 2020. In every single case, patient long-term investors recovered and grew their wealth. Short-term panic sellers did not.
