1992 Indian stock market scam

The techniques used by Mehta involved having corrupt officials sign fake cheques, abusing market loopholes, and using fabrication to drive stock prices up to 40 times their original value. Stock traders making good returns as a result of the scam were able to fraudulently obtain unsecured loans from banks. When the scam was discovered in April 1992, India's stock market crashed, and the same banks suddenly found themselves holding millions of Indian rupees (INR) in useless debt.

1992 Scandal

Overview

This was the biggest money market scam ever committed in India, amounting to approximately ₹ 5,000 crores. The main perpetrator of the scam was a stock and money market broker, Harshad Mehta. It was a systematic stock scam using fake bank receipts and stamp paper that caused the Indian stock market to crash. The scam exposed the inherent loopholes in the Indian financial system and resulted in a completely reformed system of stock transactions, including the introduction of online security systems.

Security fraud refers to the diversion of funds from the banking system to various stockholders or brokers. The 1992 scam was a systematic fraud committed by Mehta in the Indian stock market, which led to the complete collapse of security systems. He siphoned off over ₹1000 crore from the banking system to buy stocks on the Bombay Stock Exchange. This impacted the entire exchange system as the security system collapsed and investors lost hundreds of thousands of rupees. The scope of the scam was so large that the net value of the stocks was higher than the combined health and education budget of India. The scam was orchestrated in such a way that Mehta secured securities from the State Bank of India against forged cheques signed by corrupt officials and failed to deliver the securities. Mehta inflated stock prices through fictitious practices and sold the stocks he owned in these companies. The impact of the scam had many consequences, including losses incurred by lakhs of families and the immediate crash of the stock market. The index fell from 4500 to 2500, representing a loss of ₹ 1000 billion in market capitalization. The 1992 scam raised many questions about bank officials responsible for colluding with Mehta. An interview with Montek Singh Ahluwalia (Secretary, economic affairs at the Ministry of Finance) revealed that many top bank officials were involved.

Bank funds scam

In the early 60's and 70's, banks in India were not allowed to invest in the equity markets. However, they were expected to post profits and to retain a certain ratio (threshold) of their assets in government fixed interest bonds. Mehta squeezed capital out of the banking system to address this requirement of banks and pumped this money into the share market. He promised the banks higher rates of interest, while asking them to transfer the money into his personal account, under the guise of buying securities for them from other banks. At that time, a bank had to go through a broker to buy securities and forward bonds from other banks. Mehta used this money temporarily in his account to buy shares, hike up demand of certain shares (such as that of ACC, Sterlite Industries, and Videocon) dramatically, sell them off, pass on a part of the proceeds to the bank and keep the rest for himself. This resulted in stocks like ACC, which was trading in 1991 for ₹200/share, catapult to nearly ₹9,000 in just 3 months.

Bank receipt scam

Another major instrument was the bank receipt (BR). In a ready forward deal, securities were not moved back and forth in actuality. Instead, the borrower, i.e. the seller of securities, gave the buyer of the securities a BR. The BR serves as a receipt from the selling bank, and also promises that the buyer will receive the securities they have paid for at the end of the term. Having figured this out, Mehta needed banks, which could issue fake BRs, or BRs not backed by any government securities.

Once these fake BRs were issued, they were passed on to other banks and the banks in turn gave money to Mehta, plainly assuming that they were lending against government securities when this was not really the case. He took the price of ACC from ₹200 to ₹9,000. That was an increase of 4,400%. Since he had to book profits in the end, the day he sold was the day when the markets crashed.

Ready forward deal scam

The ready forward deal is a way where a single broker liaisons between two banks. When one bank wants to sell securities, it approaches the broker. This broker goes to another bank and tries to sell the securities and vice versa for buying. Since Mehta was a renowned broker, he issued cheques in his name instead of the bank. When the bank wanted money for the securities, he approached another bank and repeated the same process, and invested the bank money in the stock market. Mehta used the ready forward deal and applied it to the Bank Receipts system of the Indian financial systems. This system was the most flawed system as the Janakiraman Committee restructured the entire Bank Receipts system after the 1992 scam.

Mehta used forged BR's to gain unsecured loans, and used several small banks to issue BRs on demand. Since these banks were small, Mehta held on to the receipts as long as he wanted. The cheques in favour of both the banks were credited into the brokers' accounts which was the account of Mehta. As a result, banks made heavy investments in BOK and MCB as they showed positive signs of growth. Using the BR scam, Mehta took the price of ACC from ₹200 to ₹9000 in a short span of time. This 4400% percent increase was seen in several other stocks and as he sold the stocks, the market crashed.

This went on as long as the stock prices kept going up, and no one had a clue about Mehta's operations. Once the scam was exposed, though, a lot of banks were left holding BRs which did not have any value – the banking system had been swindled of a whopping ₹4,000 crore (equivalent to ₹340 billion or US$3.5 billion in 2026). They knew that they would be accused if their involvement in issuing cheques to Mehta was discovered. Subsequently, it transpired that Citibank brokers like Pallav Sheth and Ajay Kayan, industrialists like Aditya Birla, Hemendra Kothari, a number of politicians, and the RBI Governor S.Venkitaramanan all had played a role in allowing or facilitating Mehta's rigging of the share market.

Realization of scam and market crash

The scam first became apparent in late April 1992, when it became clear that Mehta was a disproportionately large investor in government securities. At the time, Mehta was doing more than a third of the total securities business in India. When the public realized that Mehta's investments were illegitimate and that his stocks were likely worthless, it set off a selling frenzy of Mehta's stocks. The banks that had loaned money to Mehta were suddenly holding hundreds of millions in unsecured loans. The combination of the selling frenzy and the fact that numerous banks been defrauded crashed the Indian stock market, with prices dropping 40% immediately. Stocks eventually dropped 72%, and a bear market lasted for about 2 years.
