Rumblings of Another Crash

Imagine Rohan wants to reach a jar of laddoos on the very top shelf of the kitchen. He has three sturdy biscuit tins of his own, and he stacks them into a little tower. But three tins aren't tall enough. So he knocks on the neighbour's door and borrows nine more tins, promising, "I'll give them straight back the moment you ask." Now he builds a grand tower twelve tins high, climbs up, and - brilliant - he can touch the top shelf. For a while this feels like the cleverest trick in the world. Look how high he can reach with borrowed tins!

But hidden inside that clever trick is a quiet danger, and it has nothing to do with how good Rohan is at balancing. The danger is the promise. Those nine tins aren't his. The neighbour can knock on the door and say "I want my tins back - now" at any moment, for any reason. And here is the cruel part: the neighbour is most likely to want them back on exactly the day the tower is already wobbling, when everyone is nervous. So the day Rohan most needs his tower to stay tall and steady is the very day nine-twelfths of it can be yanked out from under his feet.

That borrowed-tower trick has a grown-up name in the world of money: leverage. It simply means using borrowed money to buy more than your own money could buy. And this chapter is about one stubborn truth that the Indian stock market has learned the hard way, more than once - that a tower of borrowed blocks can stand calm and tall for years, fooling everybody into thinking it is solid, and then come down all at once in a single terrible rush. India saw a leverage-fuelled market break in 1992, and then, less than a decade later, watched a strikingly similar thing happen again around 2001. Same shape, different year. The blocks were borrowed; the neighbour asked for them back; the tower fell.

Our whole job here is to understand why the same script keeps replaying - and how an ordinary person keeps their own money out of the falling tower. The first rule isn't to reach the highest laddoo; it's to make sure that whatever happens, nobody can yank the ground out from under you and knock you clean out of the game.

Before we watch the tower fall, we have to feel why borrowing to invest is so tempting in the first place. Because it isn't a silly thing that only foolish people do. It is a genuinely powerful trick - that is exactly what makes it dangerous. A thing that never works would never fool anybody. Leverage fools people precisely because, most of the time, it works beautifully.

Here is the magic. Suppose you have ₹100 and you buy something with it, and it goes up 10%. You now have ₹110 - a nice, honest ten-rupee gain. Now suppose instead you put in your ₹100 but also borrow ₹300, so you buy ₹400 worth of the same thing. It goes up the same 10%. Your ₹400 becomes ₹440. You hand back the ₹300 you borrowed, and you are left with ₹140. From the very same 10% move, you didn't make ₹10 - you made ₹40. Your own money grew by 40%.

Feel how thrilling that is. The market moved a gentle 10%, but your pocket moved a roaring 40%, because you were standing on borrowed blocks. This is the reason leverage spreads through a market like a happy rumour. The first people to use it look like geniuses. They aren't picking better companies than their careful neighbours; they are simply standing on a taller tower, so every small step the market takes lifts them four times higher. Word gets around. Everyone wants tins.

But - and this is the whole point - a lever works in both directions. The same borrowed blocks that multiply your gains by four will multiply your losses by four just as faithfully. The lever doesn't know which way you want to go; it only knows how to make things bigger. And a loss made four times bigger is a very different animal from a gain made four times bigger, for one simple reason we will keep coming back to: a big enough loss doesn't just hurt, it ends the game. You cannot play tomorrow with money that no longer exists. That asymmetry - gains you enjoy versus losses that can finish you - is why borrowing to invest deserves a great deal more fear than it usually gets.

Now let's look closely at the machinery, because the danger doesn't live in the borrowing alone. It lives in a small, easy-to-miss rule attached to the borrowing: the lender can ask for their money back at the worst possible moment, and if you can't pay, they sell your things for you.

When you borrow money from a broker to buy shares, the broker isn't being kind. They protect themselves with a rule. They watch the value of what you bought, and if it falls past a certain line, they send you a sharp message: "Put in more cash right now, or I sell your shares immediately to get my loan back." Grown-ups call this a margin call. It is the neighbour banging on the door demanding the tins back. And notice when it comes: never on a calm sunny day when prices are high. It comes precisely when prices are already falling - because that is exactly when the broker gets scared about being repaid. So the demand to sell always arrives on the day selling is the worst possible idea.

This is what turns an ordinary loss into a catastrophe. A person using only their own money, watching prices fall, can simply wait. They can fold their arms and say, "This will pass; I'll hold." But a person standing on borrowed blocks has lost that power. They are not allowed to wait. The neighbour decides, not them. They are forced to sell into the very worst prices, locking in the loss forever, at the one moment a patient person would have done nothing at all.

So the real machinery of a leverage crash isn't complicated. It's just this: borrowing takes away your right to be patient. And patience, it turns out, is the single most valuable thing an investor owns. Borrowed money quietly swaps your greatest strength - the ability to wait - for someone else's permission, and hands them the switch to sell you out at the worst possible moment.

Let's put real rupees on the table and watch leverage during the good times, because you can't understand the crash until you've felt how lovely it is right before. illustrative

Meet Arjun. He has saved ₹1,00,000. His broker offers him a deal that sounds like free money: "For every rupee of yours, I'll lend you three. Put in your ₹1,00,000 and I'll add ₹3,00,000, and you can buy ₹4,00,000 of shares." Arjun buys a spread of popular shares with the full ₹4,00,000.

In the first year, the market drifts up a calm 10%. Arjun's ₹4,00,000 of shares becomes ₹4,40,000. He still owes the broker exactly ₹3,00,000 - a loan doesn't grow. So his own slice is ₹4,40,000 minus ₹3,00,000, which is ₹1,40,000. He started with ₹1,00,000 of his own; now he has ₹1,40,000. A sleepy 10% market has turned into a 40% gain for Arjun.

The next year, another quiet 10% up. His shares climb from ₹4,40,000 to about ₹4,84,000; take away the ₹3,00,000 loan and his own slice is ₹1,84,000. Meanwhile his careful cousin Aayra, who used only her own ₹1,00,000 and borrowed nothing, has grown hers to about ₹1,21,000 over the same two calm years. Arjun looks at Aayra and feels a little sorry for her. He is winning so much more, so easily. He starts to think the borrowing wasn't risky at all - look, two whole years and nothing bad happened! In fact, he decides, he was too timid. Next time he'll borrow even more.

Sit with that feeling, because it is the trap closing softly. Nothing about Arjun's shares was safer than Aayra's - they own almost the same companies. The only difference is that Arjun is standing on a tower of borrowed blocks, so every gentle step up lifts him four times higher. The calm years haven't proven that his tower is solid. They've only proven that the neighbour hasn't knocked yet. But Arjun can't tell those two things apart, and neither can most people. The absence of disaster feels exactly like safety, right up until the moment it doesn't.

Here is the strangest twist in the whole story, and the one worth slowing right down for: the long stretch of calm isn't the reward for being safe. It is the thing that builds the danger.

Think again about Rohan's tower of tins. On day one, when he first borrows nine tins, he is nervous. He climbs carefully, he keeps one hand on the wall, he doesn't lean. But the tower doesn't fall on day one. Or day two. Or day fifty. And a funny thing happens inside Rohan's head. Every day the tower stays up, his fear shrinks a little. "See? It's fine. I've been doing this for weeks." So he starts to relax. He climbs faster. He stops holding the wall. And - this is the crucial bit - he borrows more tins to build an even taller tower, because the first tower "obviously" was safe. The longer nothing goes wrong, the bolder he gets, and the taller and thinner and wobblier the tower grows.

Now multiply Rohan by a whole market. When shares have risen calmly for a few years, everybody's fear shrinks together. Brokers, seeing no disasters, happily lend more. Ordinary people, seeing their neighbours get rich on borrowed money with no punishment, borrow too. The ones who stayed careful start to feel like fools, so they give in and borrow as well. Slowly, invisibly, the whole market climbs onto taller and taller towers of borrowed money - not despite the calm, but because of it. The peace itself is manufacturing the fragility. And the worst part is that from the outside it looks the safest it has ever looked, right at the moment it has quietly become the most dangerous it has ever been.

This is one of the deepest patterns in all of investing, and it has a name worth carrying for life. A long calm doesn't make a market safe - it teaches everyone that borrowing is harmless, so they borrow more and more, quietly stacking the very fragility that will one day break. The peace isn't the opposite of the crash. The peace is where the crash is grown.

Now let's return to Arjun and watch the same lever run the other way. illustrative

Arjun, feeling clever after two calm years, has done exactly what the calm taught him to do: he borrowed even more. He now has ₹1,80,000 of his own (his original money plus his gains), and he has borrowed enough to be holding a great tall tower of shares - let's say ₹7,00,000 of shares against ₹5,20,000 of borrowed money. Then, one ordinary week, the mood in the market simply turns. No single reason. Prices start to slip.

They fall 10%. Arjun's ₹7,00,000 of shares drops to ₹6,30,000. He still owes ₹5,20,000, so his own slice has shrunk from ₹1,80,000 to ₹1,10,000. A 10% market dip has cut his money by nearly 40% - the lever, faithfully working in reverse. He tells himself to stay calm, that it will bounce back. And on his own money, he could wait. But he isn't on his own money.

The next morning, the margin call arrives. The broker's rule has been crossed. The message is blunt: put in more cash today, or we sell your shares now. Arjun doesn't have more cash - it's all in the tower. So the broker sells. Not at yesterday's price, not at a price Arjun chooses, but at whatever the frightened market will pay this morning, which is the worst price of all. By the time the forced selling is done and the ₹5,20,000 loan is repaid, Arjun's own slice - which was ₹1,80,000 a week ago - is worth around ₹40,000. And here is the part that truly hurts: within a couple of months the market steadies and drifts back up. Aayra, who never borrowed, barely felt the dip; she simply held her shares and watched them recover. Arjun didn't get to hold anything. He was sold out at the very bottom, and the recovery happened without him, because he wasn't in the game to see it.

Let's line the two cousins up side by side once the dust settles, because the scoreboard is the whole lesson in one glance. Aayra never borrowed a rupee; when the market dipped 10% her shares dipped 10% too, from about ₹1,21,000 to ₹1,09,000, and a few months later they were back above where they started - she barely remembers the week. Arjun, holding the same shares on a tower of borrowed blocks, went from ₹1,80,000 to roughly ₹40,000, and unlike Aayra he had no shares left to recover with, because they'd been sold out from under him. Same shares. Same dip. Same rebound. One cousin shrugged; the other was ruined. The only difference in the entire story was the borrowed blocks.

Look carefully, then, at what actually ruined Arjun. It was not that he picked bad companies - he owned almost the same shares as Aayra, and hers were fine. It was not even that prices fell; falls happen and patient people wait them out. What ruined him was that the borrowing took away his patience at the one moment patience was worth everything. The lever magnified a survivable 10% dip into a total wipeout, and the margin call made sure he couldn't wait for the rebound. Aayra's ordinary bad week and Arjun's ruin were the same market - only one of them had promised his blocks to a neighbour.

We've watched one person's tower fall. But 1992 and 2001 weren't one person - they were a whole market coming down together, and to understand that we need one more step: how a single collapse spreads into a stampede.

Here is the chain, and it's worth walking through slowly because it explains why leverage crashes are so violent. illustrative When Arjun is force-sold, his broker dumps a big pile of shares onto the market all at once. That extra selling pushes prices down further. But Arjun isn't the only one on a borrowed tower - there are thousands of Arjuns, and the whole market climbed onto borrowed blocks during the calm. So the lower prices caused by Arjun's forced selling now trip the margin-call line for the next borrower, who is force-sold too, dumping more shares, pushing prices lower still, tripping the next borrower. Each forced sale becomes the cause of the next one. It is a line of dominoes where every domino that falls knocks over two more.

And it gets worse, because the brokers themselves were often borrowing too - borrowing to lend to the Arjuns. When enough of their customers can't pay, a broker can't repay their lenders, and the broker itself defaults. Now it isn't just individual investors being wiped out; it's the machinery in the middle breaking. That is precisely the shape of what India lived through in 1992 and again around 2001: leverage that had piled up quietly during calm years, a wobble that turned into forced selling, forced selling that fed on itself, and brokers in the middle who defaulted when the chain snapped. Two different decades, the very same machine.

And now step all the way back and you can see the biggest shape of all: this is not a one-time accident that got fixed. It is a cycle. The calm builds the borrowing; the borrowing builds the fragility; the fragility breaks into a crash; the crash scares everyone off borrowing for a while; the scars heal; a new calm begins; and slowly, as a fresh set of people who never felt the last crash climb onto fresh towers of borrowed blocks, the whole thing winds up to do it again. Markets don't fall once and learn forever - they move in cycles, and the danger is always largest at the top, in the calm, exactly when the fewest people can remember the last time it broke. The reason 2001 could rhyme so closely with 1992 is that a market has no single memory. Each generation of towers is built by people for whom "it stayed up last time" is the only lesson that feels real.

The slip is almost never "I decided to gamble with borrowed money." Nobody frames it that way. The slip is much quieter and much more human: mistaking a long calm for proof of safety.

Watch how it works on an ordinary, sensible person. They start out cautious. They see others borrowing and getting rich, and at first they resist. But the market keeps rising, month after month, and the careful person begins to feel not wise but silly - like the only child at the party not eating cake. The pain of watching others win is loud and daily, while the danger they're avoiding is silent and invisible. So, slowly, they talk themselves into it: "It's been three good years. The scary stories are ancient history. Just a little borrowing - I'll be careful, and I'll get out before any trouble." Every one of those thoughts is the calm doing its work, shrinking the fear right when the fear is most needed. And the plan to "get out before any trouble" is a fantasy, because trouble in a leverage crash arrives as a margin call overnight, not as a polite warning you can act on.

Now the honest part, because even a true warning can be twisted into a silly rule if you push it too far.

The lesson of this chapter is not "all borrowing is evil and nobody should ever owe anyone anything." That would be its own kind of foolishness. A family borrows sensibly to buy a home they'll live in for thirty years, and that's usually a fine, sturdy thing - because nobody sends a margin call on a home loan you're steadily repaying; the bank can't demand the whole sum back overnight just because house prices dipped for a month. Businesses borrow to build factories that will earn for decades. The danger we've been describing is a very specific animal: short-term borrowing to buy things whose prices jump around daily, held under a rule that lets the lender force you to sell at the worst moment. It's the forced-selling part, not the borrowing part, that turns a loss into a ruin. Miss that distinction and you'll either fear all debt blindly or, worse, assume your risky margin loan is as safe as a home loan.

There's a second way this idea can mislead, and it's subtler. Knowing all this, a clever person might decide, "Fine - I'll use leverage, but I'll be the smart one who gets out in time." This is the most dangerous conclusion of all, because it keeps you playing the exact game that ruins people while flattering you that the rules don't apply to you. Arjun didn't think he was reckless either; every borrower in every calm decade believed they'd be nimble enough to escape. The trouble is that the crash doesn't announce itself, and the margin call doesn't wait for your convenience. You cannot reliably outrun a stampede you're standing in the middle of.

And a third, quieter caution: don't read "survive the crash" as "predict the crash." Nobody in this chapter needed to know when the tower would fall. Aayra didn't time anything; she didn't sell at the top or buy at the bottom. She simply refused to stand on borrowed blocks in the first place, so that whenever the fall came - this year, next year, five years on - it couldn't reach her. That's the real skill on offer here. Not seeing the future, which no one can do, but arranging your money so that you don't need to see the future to survive it. The point isn't to be the cleverest person in the market. It's to be the one who is still standing when the clever people are being sold out at the bottom.
