Five Down Weeks and a Record SIP Month: What Ten Crore Standing Instructions Understand About Falling Markets

The Nifty 50 has now fallen for five consecutive weeks. The latest was the largest of the five: down 2.09% to 23,398.10, with the Sensex down 2.27% to 74,781.76. Oil is back above $100 a barrel. Saudi Arabia shut the pipeline it had been using to route crude around the Strait of Hormuz. Markets are pricing a rate hike from the US Federal Reserve on 16 September.

In the same week, the Association of Mutual Funds in India published its August data. Indian households put ₹32,297 crore into SIPs that month — a new high. The number of SIP accounts contributing crossed 10 crore for the first time.

August was a month in which the Nifty closed lower in every week from the 10th onward. Ten crore standing instructions executed on schedule through it anyway. That gap, between what the headlines said and what households did, is worth understanding properly.

First, size the fall

“Five straight down weeks” sounds like a crisis. The phrase describes a streak, not a size, and the size is what matters to your money.

The Nifty closed at 24,570.65 on 7 August. On 11 September it closed at 23,398.10. That is a fall of 4.77% across five weeks. The weekly moves were −0.83%, −0.47%, −0.31%, −1.15% and −2.09%.

That is a real decline, and nobody enjoys watching it. It is also a fall of under 5%, spread over more than a month, in an asset most people hold for ten or twenty years. Over any long holding period, stretches like this are ordinary, not exceptional. The streak count makes it feel larger than the arithmetic does.

The first discipline in a falling market is simply to convert the headline into a number and compare that number with your actual horizon.

What actually moved prices this week

Two forces did most of the work, and neither started in India.

The first was oil. For months the Strait of Hormuz has been largely closed, and Saudi Arabia has kept exporting by pumping around 5 million barrels a day across the country through its East–West pipeline to the Red Sea. On 10–11 September, drone strikes launched from Iraqi territory hit that pipeline and Riyadh shut it. Brent crossed $100 on Wednesday and settled near $104.47, up about 9% for the week. On India’s MCX exchange, crude rose 13.15% to ₹9,759 a barrel — more than 22% in two weeks. India imports most of its oil, so this is a real cost to the economy.

The second was the price of money in America. Strong US jobs data had markets expecting the Federal Reserve to raise rates, and by Friday futures implied roughly 85% odds of a hike. US 10-year bond yields approached 4.98%, their highest since late 2023.

You can see that second force clearly in which sectors fell hardest. Nifty Realty lost 6.5% — property is the classic interest-rate-sensitive sector. Nifty IT lost 5.8%, with Infosys down 8.17% and HCL Technologies down 6.75%, because Indian IT companies earn from American clients who spend less on technology when borrowing costs rise. Just two weeks earlier, the same IT index had risen 3.51% in a single day on Nvidia’s results. Its direction was set in the United States both times.

The decision that mattered was made years ago

Here is the part that is easy to miss about that record SIP number.

Very few of those 10 crore accounts involved a decision in August. Their owners decided once — often years earlier — to invest a fixed amount every month. What they did in August was the harder thing: they did not change that decision each time the news offered a reason to.

That is not passivity. Declining to override a sound plan when the headlines are loud is one of the hardest behaviours in investing, and in August it was carried out on a national scale.

It is also mechanically sensible. A SIP instalment buys units at whatever price prevails on its date. When prices fall, the same rupees buy more units. Every instalment over the past five weeks bought at a lower price than the one before it. Stopping would turn that built-in feature into a decision you would then have to time correctly twice — once to stop, and again to restart. Very few people get the second one right.

The one pattern inside the good news

The August data carried a second message, and it deserves the same honesty as the first.

Small-cap funds took a record ₹7,973 crore in the month, and small-cap and mid-cap funds together took just over half of all equity inflows. Large-cap funds saw money leave for a second month in a row.

That followed a period in which smaller companies had comfortably outperformed the Nifty. Money following the most recent winner is one of the most reliable patterns in investing. It is also how a portfolio drifts away from the plan its owner chose, without anyone ever deciding that it should.

Small-cap funds are not a problem in themselves. They can play a sensible part in a long-term plan. The question is whether your own new money has quietly tilted toward whatever performed best last year, taking your overall allocation somewhere you never intended. That is worth checking in any week, and a falling market is a natural moment to do it.

A price you cannot sell at is not a price

One more story from the week is worth keeping, because the lesson travels well beyond it.

The National Stock Exchange fixed the price band for its IPO at ₹1,700–1,785 a share. In the unlisted market, where shares change hands privately before a listing, NSE shares had touched around ₹2,400 in June 2025. The top of the IPO band is about 26% below that peak.

Nothing about the exchange became 26% worse. The unlisted price was simply a quote between a small number of willing parties, with no obligation on anyone to honour it. The previous week, grey-market premiums had misjudged two IPO listings in opposite directions. Unlisted quotes, grey-market premiums and tips share one feature: nobody stands behind them. This is an observation about how prices are formed, not a view on whether anyone should apply for any IPO.

What a long-term investor can usefully do this week

Very little, and it helps to be specific.

Convert the fall into a number. Five down weeks is −4.77%. Compare it with the number of years your money is meant to stay invested.

Leave the standing instruction alone. The households who set a record in August did not need to be right about oil, the Fed or the pipeline. They only needed to keep going.

Check your allocation rather than the market. Ask your Relationship Manager to show your current split between large, mid, small and flexi-cap funds against the plan you started with. If recent top-ups have pulled it off course, that is a conversation worth having calmly — not a reason to react to a headline.

The one line to keep

Warren Buffett is often quoted as saying the stock market is a device for transferring money from the impatient to the patient.

This week tested impatience with every tool it had: oil, war, a pipeline and a central bank. In August, more than 10 crore SIP accounts answered by doing nothing different. Over the horizon on which people actually build wealth, that is usually the answer that holds up.
