Let me begin with a confession. When I first started investing in the mid-1990s, I was brilliant. At least, I thought I was. The markets were rising. Every stock I touched turned golden. I attended every market seminar and quietly agreed with every bull who said the only direction was up. I had opinions. I had conviction. And for a brief, dangerous moment, I had the thought: “What if I borrowed a little money and put it into the market too?”

I didn’t do it. Not because I was wise — I wasn’t, not yet. I didn’t do it because a retired uncle of mine, who had been through the 1992 Harshad Mehta scam and lived to tell the tale, grabbed me by the collar (metaphorically) and said something I have never forgotten:

That single sentence may have saved my financial life. Over the next 25 years, I watched dozens of smart, educated, well-meaning investors break this rule — and almost every single one of them paid a devastating price for it. This article is my attempt to pass that lesson on, with a bit more detail and a lot more examples than my uncle’s three-second wisdom.

What Does It Actually Mean to Invest with Borrowed Money?

Before we get into the horror stories, let’s make sure we understand what we’re talking about. Investing with borrowed money simply means taking on debt — from any source — and deploying that money into the equity markets.

This happens in several forms, and many investors don’t even realise they’re doing it:

• Margin trading: Your broker gives you leverage — you put up ₹50,000 and the broker lets you buy ₹1,00,000 worth of stocks. Great when markets rise. Catastrophic when they fall.
• Loan against property (LAP): “My house has appreciated a lot. Let me mortgage it and invest in the market to get even better returns.” This sentence has destroyed more middle-class families than I care to count.
• Personal loans: Banks offer personal loans at 14–24% interest. Some investors take these and put the money in stocks, hoping to earn 30% and pocket the difference. Sounds like easy math. It isn’t.
• Credit card debt: At 36–42% annual interest, using a credit card cash advance to buy stocks is less of an investment strategy and more of a cry for help.
• Borrowing from friends and family: “No interest, just repay when you can.” Until the market crashes and the awkward festival lunches begin.

The Fastest Way to Destroy Wealth

I want you to understand a piece of mathematics before we go further, because numbers don’t lie even when our emotions do.

Let’s say markets fall 40% — which, by the way, happens with remarkable regularity. It happened in 2000–2001, 2008, and again in early 2020. It will happen again. No one knows exactly when, but it will.

Here’s what that 40% fall looks like without leverage vs. with leverage:

That’s the mathematics of leverage in a falling market. Your losses don’t just double — they can wipe out nearly everything you put in, while the debt remains, coldly indifferent to your pain.

Now add to this the interest burden. If you borrowed ₹1,00,000 at 15% per annum, you owe ₹15,000 a year just in interest. The market needs to earn 15% just to break even — before taxes, before transaction costs, before any consideration of actual returns for you.

Bull Markets Make Everyone Feel Like a Genius

Here’s the uncomfortable truth about bull markets: they are the most dangerous time to be alive as an investor. Not because markets are falling — obviously they’re not — but because rising markets create a profound and deeply seductive illusion of skill.

I saw it in 1999 when IT stocks were tripling in months. Software engineers were moonlighting as stock traders. Taxi drivers gave stock tips. My own cousin, who was a geography teacher, had opened a margin account and was “crushing the market.” He was also, as it turned out, about six months away from a devastating margin call when the dot-com bubble burst.

I saw it again in 2007. Real estate and infrastructure stocks were zooming. A friend in Pune mortgaged his flat, took a loan against property worth ₹30 lakhs, and ploughed it all into infrastructure and power sector mutual funds and stocks. “The government is spending billions on infrastructure,” he reasoned. “How can it fail?” The 2008 crisis had thoughts on that matter.

And I saw it most recently in 2021 — when meme stocks, crypto, and small-cap darlings made every new investor feel like they’d discovered a secret that the old guard was hiding. New demat accounts were opening at over a lakh per day. Social media was full of screenshots of 200% returns. Everyone was a bull. Everyone was a genius.

Until they weren’t.

Bull markets breed a particular kind of cognitive bias called recency bias — the human brain’s tendency to believe that recent trends will continue indefinitely. When markets have been rising for two years, three years, five years, the brain quietly stops processing the possibility of a fall. The idea that “markets only go up” stops being a hope and starts feeling like a law of nature.

It is not. It never has been. It never will be.

Debt Turns Investing Into Gambling

There is a fundamental difference between investment and gambling, and it is not the activity itself — it is the consequence of being wrong.

When you invest your own money, being wrong means you lose your own money. That’s painful but survivable. Markets have always recovered. Patient investors who survived without leverage have, in every meaningful historical example, eventually been rewarded.

When you invest borrowed money, being wrong means you lose your own money AND still owe the borrowed money plus interest. That’s not just painful — it can be financially fatal.

Consider what debt does to the investor’s psychology:

• It creates a compulsory exit timeline. You must repay the loan by a certain date, regardless of where the market is. Good investing has no deadline. Good investing requires patience. Debt destroys patience.
• It makes you a forced seller. When markets crash and your broker issues a margin call — or your bank starts calling about your loan EMI — you are forced to sell at the worst possible time. Not because you want to. Because you have no choice.
• It increases emotional volatility. A 5% market drop feels like background noise when it’s your own money. It feels like an emergency when you’re leveraged. That emergency triggers panic decisions, which trigger more losses.
• It removes the most powerful tool in an investor’s arsenal: time. The greatest wealth creator in equity investing is time in the market. Debt, with its repayment deadlines, cuts your time horizon to a knife’s edge.

The Silent Stress of Leveraged Investing

Nobody talks about this enough, and I think it’s the most important point in this entire article.

Investing borrowed money doesn’t just put your money at risk. It puts your entire mental and emotional equilibrium at risk.

I knew a man — let’s call him Vikram — a senior manager at a manufacturing company in Pune. Smart man. 2006. Markets booming. He’d taken a personal loan of ₹5 lakhs “just to boost his portfolio a bit.” He told himself it was temporary, that he’d repay it in 18 months when the market gave him his expected 40% return.

By early 2008, his portfolio was up 50%. He felt invincible. He borrowed another ₹3 lakhs.

By October 2008, the Sensex had fallen 60% from its January peak. His ₹8 lakhs of borrowed money had bought assets now worth ₹3.8 lakhs. He owed ₹8 lakhs plus interest — roughly ₹9.5 lakhs by then. His actual net investment was negative. He had to liquidate his own savings, his wife’s jewellery, and borrow from family just to clear the loans.

He didn’t sleep properly for eight months. His marriage suffered. His performance at work suffered. He told me years later that the worst part wasn’t the money — it was that he’d been cheerful and optimistic when taking the loans, and the guilt of that cheerfulness haunted him through the dark months that followed.

Why I Never Broke This Rule in 25 Years

I want to be honest with you. There were moments — several of them — when the temptation was real.

In 2003, when the markets were beginning their epic recovery from the dot-com bust, a colleague kept nudging me to take a personal loan and “go all in.” “Yaar, look at the valuations. Everything is cheap. You’ll double in two years.” He wasn’t wrong about the market direction, as it turned out. But I still said no. Because I didn’t know what I didn’t know. And I knew that I didn’t know.

In 2020, after the COVID crash, I had every reason to believe the market would recover strongly. Central banks were printing money. Valuations were attractive. I was genuinely excited. But I invested only my surplus cash — money I could genuinely afford to lock away without anxiety. I never touched a loan.

My rule has always been simple:

This rule meant I missed some upswings. I underperformed some leveraged investors in bull years. But it also meant I sailed through 2000, 2008, and 2020 without a single forced sale, without a single sleepless night caused by a margin call, and without once questioning whether my investing strategy was going to destroy my family’s future.

That peace of mind is not a soft benefit. It is a concrete, quantifiable advantage that compounded over 25 years into significant wealth preservation and growth.

Behavioural Finance: Why Smart People Make This Mistake

If this is such an obviously bad idea, why do intelligent, educated investors keep doing it? Behavioural finance has some fascinating and humbling answers.

Overconfidence Bias

Studies consistently show that investors overestimate their ability to predict markets. After a run of successful investments, the human brain begins to attribute market gains to personal skill rather than market conditions. “I’ve called three consecutive up years correctly. I obviously know something.” This inflated self-confidence makes borrowing feel like a rational extension of an edge that doesn’t actually exist.

Availability Bias

We make decisions based on recent memories. If the last thing you remember is markets going up for three years, that’s what feels “normal.” The 2008 crash feels distant and unlikely. The COVID crash feels like a one-off. The brain waves away inconvenient historical data and clings to the recent trend.

FOMO — Fear of Missing Out

When your colleague, your brother-in-law, and three people in your apartment building WhatsApp group are all making money and talking about it loudly, the social pressure to participate is immense. Borrowing to invest often happens not because of careful analysis, but because the pain of not participating feels worse than the risk of borrowing.

Loss Aversion Paradox

Ironically, loss aversion — our tendency to feel losses more acutely than gains — can lead people to take bigger risks to “recover” losses. An investor who’s down ₹2 lakhs on a bad trade may borrow money to “average down” and recover, doubling down on a losing position with borrowed capital. This is how small mistakes become large disasters.

Anchoring to Peak Returns

If a market or stock returned 60% last year, investors unconsciously anchor to that number as a baseline expectation. They borrow because they assume similar returns will cover the cost of debt. Anchoring to past performance while ignoring the possibility of mean reversion is one of the most reliable paths to financial pain.

How Debt Destroys the Most Powerful Tool in Investing: Patience

Here’s something I want you to genuinely sit with for a moment.

The single most important edge a retail investor has over institutions, over hedge funds, over every sophisticated player in the market, is this: you don’t have to do anything.

You can hold a quality company for 10, 15, 20 years. No hedge fund can do that without facing redemptions. No institutional manager can do that without facing quarterly performance reviews. But you, investing your own money at your own pace, can simply wait. You can let compounding do what compounding does, which is create seemingly impossible amounts of wealth over long periods.

Debt eliminates this advantage completely.

When you have a loan, you have a repayment timeline. When you have an EMI, you have a monthly outflow that creates constant pressure. When markets fall — as they inevitably do — and your loan still needs repaying, you cannot simply wait. You must either:

• Sell assets at a loss to service the loan
• Take more debt to repay the old debt (a death spiral)
• Liquidate other assets — emergency funds, fixed deposits, family savings — to stay afloat

Each of these options is worse than simply having invested with your own money and holding through the downturn.

The SIP Investor vs. The Leveraged Investor: A Tale of Two Approaches

Let me paint you two pictures — same person, same ambition, radically different outcomes.

Priya is boring. Nobody posts about her on social media. Nobody at parties asks her about her hot stock picks. But over twenty years, Priya is likely to be significantly wealthier — and far less stressed — than every Rohan who went the leverage route.

The Difference Between Courage and Recklessness

One thing I hear often from investors who borrow to invest is that they’re being “bold” or “entrepreneurial.” And I want to gently but firmly push back on that.

Courage in investing means staying invested through a market crash when everyone around you is selling. It means buying quality stocks when they’re deeply unpopular and sentiment is at its darkest. It means having the conviction to hold a position through years of underperformance if your original thesis remains intact.

Recklessness is buying things you can’t afford with money you don’t have, in the hope that markets will cooperate with your repayment schedule.

Courage is sustainable. It requires no particular skill to weather a storm in a solid house. Recklessness requires everything to go right — markets must rise, they must rise fast enough, they must stay up long enough for you to exit profitably, and all of this must happen within your loan tenure. That’s not investing. That’s wishful thinking with interest payments attached.

Why Peace of Mind Is an Underrated Financial Asset

I have met very wealthy investors over the past two and a half decades. Some of them made extraordinary amounts of money through leverage and came out intact — I won’t pretend that’s impossible. But I have never once heard a deeply leveraged investor describe their journey as peaceful or enjoyable, even in hindsight.

And the ones who came out intact were often survivors of enormous luck as much as skill. They happened to borrow at the right time, markets happened not to crash badly during their loan tenure, and everything worked out. Repeat that experiment enough times, and the law of large numbers will catch up. Eventually, the crash comes at the wrong moment. Eventually, the margin call arrives. Eventually, the EMI cannot be paid from a falling portfolio.

Investing your own money means you can genuinely not check your portfolio for three months and feel fine. You can go on a holiday without checking stock prices. You can read a negative market headline and shrug because you know — with complete certainty — that you are under no obligation to sell. That freedom is priceless.

Lessons Across Market Cycles: What 25 Years Teaches You

The Dot-Com Era (1999–2001)

Technology stocks were supposed to change the world. They did — eventually. But first they fell 70–90%. Every leveraged investor in those stocks was wiped out before the recovery arrived. Unleveraged, patient investors who held quality companies recovered and went on to enormous gains. But they had to be alive — financially — to see the recovery. Leveraged investors weren’t.

The 2008 Global Financial Crisis

The Sensex fell from 21,000 to 8,000 — a fall of over 60%. If you had taken a loan against property in 2006–2007 to invest in infrastructure or real estate stocks, you were facing the prospect of losing not just your portfolio value, but potentially your home too. This was not a theoretical risk. This happened to real people with real families in real Indian cities.

The COVID Crash (March 2020)

Markets fell 38% in roughly five weeks. Margin call season arrived with unusual speed. Traders on leverage were obliterated before they could react. But investors with no debt who simply held — or better, kept buying via SIP — saw their portfolios multiply over the following eighteen months. The recovery from COVID was the fastest in modern market history. Leveraged investors missed it because they were forced out at the bottom.

A Slow Investor Often Becomes a Rich Investor

I want to leave you with perhaps the most counterintuitive insight from 25 years of watching markets:

The investors who built the most wealth were rarely the most aggressive ones. They were the most patient ones. The ones who put away ₹5,000 a month, every month, through good times and bad, for 15–20 years. The ones who didn’t try to outsmart the market, didn’t time it, didn’t borrow to accelerate it — just let time and compounding do the heavy lifting.

There’s something almost anticlimactic about the truth of wealth creation. It doesn’t involve genius. It doesn’t involve insider knowledge. It doesn’t involve leverage or sophisticated derivatives or multi-bagger stock picks shared by an influential Twitter account.

It involves: surplus money, consistent investment, diversification, patience, and — most critically — staying in the game long enough for compounding to work its quiet, extraordinary magic.

Borrowed money cuts your time in the game. Your own money, invested patiently, extends it indefinitely.

The Power of Surviving Market Cycles

Here is what 25 years of investing has taught me about market cycles:

• Bull markets end. Always. Without exception.
• Bear markets also end. Always. Without exception.
• The question is never whether the market will recover. It always does. The question is whether you will still be in it when it does.
• Leveraged investors are eliminated from the game at precisely the moments when they should be accumulating.
• Unleveraged investors with patience and surplus capital are given the extraordinary opportunity to buy great companies at panic prices during crashes — and they can take that opportunity because they aren’t under pressure to sell.

Survival is the most underrated skill in investing. Not picking the right stock. Not timing the market. Simply surviving — remaining financially solvent, emotionally stable, and invested — through the inevitable downturns.

Leverage is the greatest threat to that survival. And this is why — in 25 years, through multiple cycles, through opportunities that looked irresistible, through bull markets that made borrowing seem like the obvious move — I never once invested borrowed money into equity markets.

Not once. And I have never regretted it.

Conclusion: The Principle That Outlasts Every Bull Market

Markets will boom again. Tipsters will reappear. Friends will share screenshots of 3x returns. The whisper network will hum with talk of “sure bets.” And somewhere, someone will be arranging a personal loan to invest in the next big thing.

I hope that person is not you.

Because here’s the truth I’ve learned across 25 years, four major crashes, three epic bull markets, and more market cycles than I can count: wealth is built slowly, carefully, and with one’s own money. It is protected by discipline, patience, and an almost boring refusal to do exciting, dangerous things with borrowed capital.

The markets will reward patience. They have always rewarded patience. But they will only reward patience if you are still standing when the reward arrives — and borrowed money has a remarkable talent for making sure you’re not.

Invest with your own money. Invest only what you can truly afford to lose. Take the long view. Sleep well at night. And let time and compounding do what no loan, no leverage, and no margin account can ever do: build lasting, sustainable, peaceful wealth.
