Paper 43 · 10 min read
When markets fall, the instinct is to "pause the SIP until things settle." It feels prudent. It is the single most expensive thing an SIP investor can do — because the instalments you skip in a downturn are the ones buying units at the deepest discount you will ever see. Pause for a year and you don't lose a year of contributions. You lose a multiple of them.
The whole power of a Systematic Investment Plan is rupee-cost averaging: a fixed amount buys more units when the price is low and fewer when it is high. The falls are not the enemy of the SIP — they are the source of its edge. The cheap units bought during a crash are what generate the outsized returns when the market recovers.
Pausing the SIP in a downturn does the exact opposite of what the plan is designed to do. It switches off the buying at the precise moment buying is most valuable. You keep the SIP running through the expensive years at the top and switch it off through the cheap months at the bottom — buying high and refusing to buy low, on autopilot, in reverse.
And the harm is not the missed instalments. It is what those particular instalments would have bought. Skip ₹3 lakh of contributions across a 12-month crash and you have not lost ₹3 lakh — you have lost the ₹13–15 lakh those cheap units would have grown into. The instalments are small; the units they buy at the bottom are not.
A ₹25,000 monthly SIP over 20 years at 11%. In one version it runs uninterrupted through a mid-way crash. In the other, the investor does the natural thing — pauses for the 12 months the market is down and scary, then restarts once it has recovered. The only difference is those twelve skipped instalments.
The multiplier is the whole point. In every other month, ₹25,000 buys units at roughly fair value. In the crash months, that same ₹25,000 buys units at a deep discount — units that then ride the entire recovery. Removing exactly those instalments removes the most productive rupees in the whole plan.
The simulation above is generous — it assumes you restart the SIP the moment the crash bottoms, exactly 12 months later. Real investors don't. The same fear that stopped the SIP keeps it stopped: you wait for "confirmation" the recovery is real, which by definition arrives only after prices have already climbed back. A pause intended for a few months routinely stretches to a year or two — and every extra month is another block of cheap units forgone.
This is why SIP persistency — simply keeping the instruction running — is one of the strongest predictors of whether an investor reaches their goal. Not fund selection. Not timing. Just: did the SIP keep going through the years it felt worst to continue.
For the advisor, the crash is the moment the whole relationship earns its keep. Not with a clever call or a fund switch — with a single, boring instruction held firm: do not pause the SIP. The client who keeps buying through the fear is not braver than the one who stops. They just had someone to tell them that the falling market was not the problem to be escaped — it was the opportunity the plan was built to capture.
