Harshad Mehta Scam — What Actually Happened

The Harshad Mehta scam was a 1991–92 stock-market manipulation scheme in which broker Harshad Mehta diverted inter-bank lending money — meant for government-bond settlements — into shares using fake or unbacked bank receipts. Cash that powered the rally evaporated when journalist Sucheta Dalal exposed the loophole on 23 April 1992, crashing the Sensex by 43%.

If you've watched Scam 1992 on Sony LIV, or read about Harshad Mehta in passing, you probably know the broad strokes. A broker. A bull run. A fall.

What you may not have learned is how the actual mechanism worked: the bank receipt, the ready-forward deal, and the fact that the entire scheme leaned on trust between banks more than on outright forgery, at least at the start.

That's what this article is for. I want to walk you through what Mehta actually did in language a beginner can follow, and end with three things from his story that any Indian retail investor should still be paying attention to in 2026.

The system Mehta was gaming

Before you can understand the scam, you have to understand the boring plumbing it abused. Bear with me — this is the part most retellings skip, and it's the part that actually matters.

In the early 1990s, every Indian bank had to keep a chunk of its deposits parked in government bonds. The Reserve Bank's Statutory Liquidity Ratio (SLR) demanded it. Miss the ratio at the end of the reporting fortnight, and you got penalised.

But banks don't always have the exact bonds they need on the exact day they need them. So they lent each other government securities for short windows (typically 15 days). The lending bank got the bond back at a small premium; the borrowing bank got a temporary float. This was called a ready-forward (RF) deal.

Here's where it gets interesting. Banks didn't physically move the bonds back and forth every fortnight. That would have been operationally insane. Instead, the lending bank issued a bank receipt (a BR), confirming that the bonds existed and would be delivered on settlement.

A BR was an IOU between two banks. Worth nothing on its own. Worth crores if you trusted the bank that issued it.

And in the middle of these RF deals sat brokers. Their job was to introduce the two banks, take a small commission, and step out of the way. They were never supposed to handle the cash or the securities themselves.

Mehta — and a handful of his peers — slowly turned that custom inside out. He convinced banks to write the cheques in his name, "for a few days," promising to settle directly with the counter-party bank. In those few days, that money sat in his personal trading account.

The scheme escalated. With the help of two small banks, the Bank of Karad (BOK) and the Metropolitan Co-operative Bank (MCB), Mehta started getting fake BRs issued. Receipts not backed by any government bond at all. Just paper.

Those fake BRs went to other banks as collateral. The other banks, trusting the system, sent cash.

The cash went into shares. The shares went up. Mehta sold a sliver, settled the BR, and started the cycle over with a bigger denomination.

How the bull run actually got built

Once Mehta had bank money in his trading account, even briefly, he could do what brokers were never supposed to do — trade with it. And he picked his stocks carefully.

Cement major Associated Cement Company (ACC) was his most famous canvas. Apollo Tyres, Reliance, TISCO, Sterlite, Videocon, BPL. All of them rallied dramatically while he was running the play. He wasn't picking obscure names; he was picking respectable, recognisable index stocks where his buying could be passed off as institutional conviction.

To justify the runaway prices, he sold a story to anyone who would listen. He called it the replacement cost theory: the idea that ACC's market cap should be priced at what it would cost to physically rebuild every cement plant from scratch. By that logic, even ₹9,000 a share was a bargain.

It wasn't economics. It was a sales pitch dressed in MBA language. But it worked, because the surrounding conditions were perfect for it.

India had just opened up under Manmohan Singh's 1991 reforms. The Sensex went from around 1,100 in early 1991 to 4,467 by 23 April 1992 — a 274% return in barely a year. Taxi drivers, paan-shop owners, salaried professionals all rushed in. Anything Mehta touched looked like a 5x in months.

He drove ACC from roughly ₹200 to nearly ₹9,000, a 4,400% gain in a single name. He bought a 15,000-square-foot sea-facing apartment in Worli with a swimming pool, a fleet of imported cars including a Toyota Lexus that cost ₹40 lakh in an India that had barely seen one before, and the press began calling him the Amitabh Bachchan of the stock market.

How it ended

On 22 April 1992, a tip-off walked into the news editor's office at The Times of India in Mumbai. State Bank of India had asked Harshad Mehta to pay back ₹500 crore — a number that didn't make sense unless something much larger was wrong with the bank's books.

The reporter who took the story was Sucheta Dalal. She had been covering the government securities desk for nearly a decade and was one of the few journalists in India who actually understood the inter-bank market. She also happened to be one of the few who hadn't been invited to Mehta's parties.

Her column ran on 23 April 1992. Within days, the BR mechanism was public knowledge.

Mehta wasn't exposed by the regulator, the bank board, or a forensic auditor. He was exposed by one journalist who refused to be a fan.

The unravelling was fast. SBI confirmed the missing securities. Banks that had taken Mehta's BRs as collateral suddenly realised they were holding paper. They started calling in their loans all at once.

Mehta normally settled bank liabilities by selling stock — but the moment the news hit, his stocks collapsed. He had no exit. The same liquidity that had built the rally evaporated with him on the wrong side of it.

The Sensex fell from 4,467 in late April 1992 to 2,529 by August — a 43% crash in roughly four months. The CBI registered 27 criminal charges against him, and over 600 civil suits piled up. He was banned from the markets for life.

Casualties spread well beyond Mehta. The chairman of Vijaya Bank reportedly died by suicide in the aftermath. Senior treasury officials at SBI, UCO Bank and the National Housing Bank lost their jobs. The RBI faced relentless parliamentary scrutiny.

Mehta died of a heart attack in Thane prison on 31 December 2001, at the age of 47. Of the 27 criminal charges he was facing at the time, only 4 had resulted in conviction. Many of the proceedings were still unresolved at his death, and the legal aftermath continued in various courts for years.

One small, telling detail: market lore widely credits two now-legendary investors, Rakesh Jhunjhunwala and Radhakishan Damani, with being on the bear side of the 1992 bull run, betting that the rally's underlying numbers couldn't justify the prices.

The same skill that lets a trader spot a manufactured bubble is the skill that compounds wealth across a career.

Three things this story teaches us today

1. When liquidity is the engine, the chart is lying to you

The most common defence Mehta's followers offered then, and still offer now, is "but the stocks went up, didn't they?" They did. The point is why.

ACC didn't sell ₹8,800 worth of additional cement per share between 1991 and 1992. The cement plants didn't multiply by 44. Only the buying did.

Whenever a stock rallies hard with no corresponding change in earnings, market share, capacity, or order book — slow down. The chart is telling you somebody is buying with conviction. It is not telling you the company is worth more.

2. Read the shareholding pattern. It tells the truth before the price does.

Concentration is a tell. When a small number of accounts are accumulating a stock aggressively, it shows up in the disclosures: promoter pledging, FII/DII flows, bulk and block deals, public shareholding ratios. All of it visible long before the crash.

This is the most actionable lesson from the entire story. You don't need to be a forensic accountant. You just need to look at the things most people don't.

3. Charisma is not a strategy

Every era has a face. In 1992 it was Harshad Mehta. In 2000 it was Ketan Parekh, a man who had once worked at Mehta's own firm.

In 2008 it was the global housing wave. In 2020 it was the SPAC mania. In 2024 it was every Telegram-channel "sir" advertising a 90% accuracy rate.

The mechanism varies. The pattern doesn't. A charismatic figure tells a confident story, the price moves with the story for a while, and the people who confused price action for proof get hurt the most when the story stops working.
