The 1992 Harshad Mehta Scam: When Borrowed Billions Fuelled a Bubble
When prices are driven by borrowed money rather than business value, the unwind is only a matter of time — always ask WHO is buying and with WHOSE money.
In the early months of 1992, the Indian stock market felt like a place where anyone could get rich overnight. The Bombay Stock Exchange (BSE) Sensex, which hovered around the 1,000 level in early 1991, rocketed to an all-time high of approximately 4,467 points by April 2, 1992. Ordinary retail investors watched in disbelief as shares of industrial companies climbed to astronomical heights. The poster child of this boom was Associated Cement Companies (ACC), which saw its share price driven from around ₹200 to over ₹9,000 during this intense speculative run. It seemed like a new era of prosperity, partially supported by the genuine positive market sentiment generated by India's 1991 economic liberalization. But beneath the surface, this monumental rally was not built on corporate earnings or economic fundamentals. It was fueled by a secret pipeline of diverted bank funds.
The setup
To understand how this happened, one must look at the structural flaws of the Indian financial system in the early 1990s. Public sector banks at the time suffered from manual ledger systems, weak internal controls, and a lack of modern technology. When banks needed short-term liquidity, they engaged in "ready-forward" (RF) deals—essentially short-term loans secured by government securities. However, the RF market lacked a centralized, real-time registry to track these physical securities. Instead of transferring actual bonds, banks issued Bank Receipts (BRs) as temporary proof of the transaction. This manual, trust-based system had a massive loophole: brokers acted as market makers and intermediaries in these interbank transactions. This allowed prominent stockbrokers, most notably Harshad Mehta, to hold and divert large sums of cash during settlement lags.
What happened
Beginning in early 1991, Harshad Mehta aggressively leveraged diverted interbank funds to purchase equities. By late 1991, he targeted specific stocks like ACC, using these ready-forward deal funds to buy up massive blocks of shares and drive prices upward. The mechanism relied on systemic collusion. Small private banks, such as the Bank of Karad (BoK), and RBI-owned institutions like the National Housing Bank (NHB) issued fake Bank Receipts that were completely uncollateralized by actual government securities. Mehta used these fake receipts to siphon hundreds of crores of rupees from public sector giants like the State Bank of India (SBI) directly into his personal brokerage accounts. The cash was then used to corner shares in the stock market, creating a self-fulfilling prophecy of rising prices.

Why it worked, until it didn't
The system worked as long as the cash kept flowing and the settlement cycles could be rolled over. But with manual ledgers and weak reconciliation, a reckoning was inevitable. In February 1992, the management of the State Bank of India detected a shortfall in its government securities ledger, indicating an unauthorized diversion of funds. The bubble began to crack. On April 23, 1992, journalist Sucheta Dalal published a ground-breaking exposé in The Times of India. The report revealed that Harshad Mehta had used fake Bank Receipts to siphon funds from SBI, starting with an initial reported shortfall of ₹500 crore.
Once the source of the capital was exposed, the credit pipeline dried up instantly. The market, deprived of its artificial liquidity, went into a tailspin. Over the year following the exposure, the BSE Sensex dropped by approximately 50%. While the total estimated scam size was a staggering ₹4,000 to ₹5,000 crore, this figure did not represent permanently lost cash; instead, it reflected a complex web of asset locks, tax claims, and massive settlement backlogs that took years to untangle. Investigations also revealed that Mehta was not the sole perpetrator, as foreign banks like Citibank and ANZ Grindlays were also systemically involved in similar irregular securities transactions.
The aftermath
The shock of the 1992 scam forced a complete overhaul of the Indian financial infrastructure. To prevent brokers from exploiting settlement lags, the Reserve Bank of India introduced the Delivery Versus Payment (DVP) system, securing interbank government securities transactions. The Securities and Exchange Board of India (SEBI), which had been granted statutory powers via an ordinance in January 1992, was subsequently given comprehensive enforcement powers to police capital markets. To eliminate the risks of physical certificates, the Depositories Act of 1996 was passed, ushering in the dematerialisation of shares. Furthermore, the National Stock Exchange (NSE) was established in 1992 to provide a transparent, electronic limit order book system, ending the era of opaque trading floors.
