Key Takeaways
- SIPs during market crashes buy more units at lower prices. This is rupee cost averaging working for you
- Historically, investors who continued SIPs through every correction outperformed those who paused by 1.5-2.5% CAGR
- The urge to pause is behavioral, not rational. 63% of SIP investors who pause never restart
- If you have surplus cash during a crash, consider increasing your SIP, not pausing it
Why Your Brain Tells You to Stop
When the Nifty drops 15% in a month, your portfolio shows red, and financial news runs apocalyptic headlines, your brain screams “stop the bleeding.” This is loss aversion. It’s the single biggest destroyer of long-term wealth in India.
Here’s what’s actually happening: your SIP is now buying units at a 15% discount. The same ₹10,000 that bought 100 units last month now buys 115 units. Over the next recovery (and every correction in Indian markets has been followed by a recovery), those extra units compound.
63% of Indian investors who pause their SIP during a correction never restart it. They wait for the "right time," which never feels right, and miss years of compounding. The pause becomes permanent.
The Math: Pausing vs. Continuing
Let’s look at real numbers. Two investors start a ₹10,000/month SIP in a Nifty 50 index fund. Investor A continues through every correction. Investor B pauses for 6 months during each major dip (2008, 2011, 2015, 2018, 2020).
Same monthly amount. Same fund. The only difference: Investor A kept investing when it felt terrible. That “terrible” feeling was actually the best buying opportunity.
Between 2008 and 2023, the Nifty 50 had 7 corrections of 10% or more. Investors who continued SIPs through all 7 earned a CAGR of 13.2%. Those who paused during corrections earned 10.8%. A 2.4% CAGR gap compounds into lakhs over a decade.
How Rupee Cost Averaging Actually Works
Rupee cost averaging isn’t a strategy you choose. It’s a mathematical consequence of investing a fixed amount regularly.
| Market Condition | NAV | ₹10,000 Buys | Units |
|---|---|---|---|
| Normal market | ₹100 | ₹10,000 | 100 |
| 20% correction | ₹80 | ₹10,000 | 125 |
| 40% crash | ₹60 | ₹10,000 | 167 |
| Recovery to ₹100 | ₹100 | ₹10,000 | 100 |
During the crash, you accumulated 167 units instead of 100. When the market recovers to the same level, those extra 67 units represent pure additional wealth, created by the correction itself.
The correction wasn’t a threat to your SIP. It was fuel for it.
What You Should Actually Do During a Market Crash
- Keep your existing SIPs running. Don’t log into your mutual fund app to check daily. Set it and forget it.
- If you have surplus cash, increase your SIP temporarily. A 20% correction is a 20% sale on future wealth.
- Revisit your asset allocation, not your SIP. If the crash is making you anxious, your equity allocation might be too high for your risk tolerance. Adjust allocation, don’t stop investing.
- Remember the base rate. Every single correction in Indian market history has been followed by a recovery. Every one.
The best investors during corrections aren't the ones with the best analysis. They're the ones with the best systems. Automated SIPs that run regardless of market conditions. Delegation removes the emotional decision point entirely.
