The Harshad Mehta scam is one of the most infamous financial frauds in Indian stock market history. Even decades later, Scam 1992 continues to be discussed by investors, regulators, and anyone interested in understanding how loopholes in the system can be exploited. Popularly known as the “Big Bull,” Harshad Mehta changed the face of Dalal Street forever – both positively and negatively.
This detailed guide breaks down the Harshad Mehta scam story, how it worked, why it shook India’s financial system, and what modern investors can learn from it.
Who Was Harshad Mehta?
Harshad Shantilal Mehta was a stockbroker who rose from humble beginnings to become one of the most powerful traders in India during the late 1980s and early 1990s. Starting as a jobber on the Bombay Stock Exchange (BSE), he gradually built a reputation for aggressive trading strategies and an uncanny ability to move markets.
At his peak, Harshad Mehta was credited with triggering a massive bull run in Indian equities, pushing the Sensex from around 1,000 points to over 4,500 points in a short span. For many retail investors, he symbolized opportunity, ambition, and fast wealth creation – until the truth came out.
What Is the Harshad Mehta Scam?
The Harshad Mehta scam refers to a massive securities fraud that took place between 1988 and 1992, involving the manipulation of the banking system to illegally divert funds into the stock market.
In simple terms, Harshad Mehta exploited loopholes in the inter-bank transaction system and used fake bank receipts to access thousands of crores of rupees. This money was then pumped into select stocks, artificially inflating their prices.
How the Harshad Mehta Scam Worked
To understand the scam clearly, it’s important to know how banking and government securities trading worked at that time.
1. Ready Forward (RF) Deals
Banks used Ready Forward deals to lend and borrow money for short durations using government securities as collateral. These deals were meant to be secure and low-risk.
2. Fake Bank Receipts
Instead of actual government securities, Harshad Mehta used fake bank receipts (BRs) issued by small banks. Large banks accepted these BRs without proper verification.
3. Flow of Illegal Money
Using these fake BRs, Harshad Mehta diverted huge sums of money from banks into the stock market. Since the money did not belong to him, this was essentially an interest-free, unsecured loan.
4. Stock Price Manipulation
He invested this money heavily in a few select stocks such as ACC, pushing prices up sharply. Rising prices attracted more retail investors, creating a self-feeding rally.
Why the Harshad Mehta Scam Collapsed
Every market manipulation eventually runs out of fuel. The Harshad Mehta scam collapsed when journalist Sucheta Dalal exposed the fraud in April 1992. Once banks started asking for their money back, the entire structure crumbled.
Stock prices crashed, banks were left with massive losses, and investor confidence was shattered.
Impact of the Harshad Mehta Scam on Indian Markets
The Harshad Mehta scam was a turning point for India’s financial ecosystem.
1. Stock Market Crash
The Sensex crashed sharply, wiping out billions of rupees in investor wealth.
2. Banking System Reforms
The scam exposed deep flaws in the banking system, leading to stricter controls and audits.
3. Strengthening of SEBI
The Securities and Exchange Board of India (SEBI) gained more regulatory powers after the scam. This marked the beginning of tighter oversight of brokers and exchanges.
4. Rise of SEBI Registered Investment Advisory
Post-scam, the importance of dealing with a SEBI registered investment advisory became increasingly evident for investors seeking transparency and accountability.
Role of Media in Exposing the Scam
Investigative journalism played a crucial role in uncovering the Harshad Mehta scam. The exposé highlighted how unchecked power, weak regulation, and blind trust can combine to create systemic risk.
Scam 1992 and Modern-Day Fraud Parallels
While the Harshad Mehta scam involved banks and stock markets, modern investors face different kinds of frauds such as cashback scams in India, fake trading apps, and unregistered tip providers.
The common thread remains the same – lack of due diligence and promises of unrealistic returns.
