Lets Decode Harshad Mehta Here…

Massive Success

He rose from being a relatively small broker in the 1980s to becoming one of the most influential market operators in India by 1991–92.

He owned luxury assets that were extraordinary for that era, including a large sea-facing residence and high-end cars.

He controlled or influenced positions worth hundreds and, at times, thousands of crores through market operations and financing arrangements.

The estimated scam exposure was around ₹4,000–5,000 crore, which gives an idea of the scale at which he was operating.

Reason Of Success

In the late 1980s and early 1990s, Harshad Mehta understood something many market participants overlooked: liquidity can move prices faster than fundamentals.

When money enters the market aggressively, prices can rise much faster than earnings. He recognized how banking liquidity, particularly through the Ready Forward (RF) mechanism, could create powerful momentum in select stocks. The Harshad Mehta episode highlights one of the most powerful forces in the stock market—liquidity.

This remains a timeless market truth:

Momentum is not magic. It is money in motion.

How things moved?

Harshad Mehta’s success was built on his understanding of liquidity and the banking system. During the early 1990s, banks frequently entered into Ready Forward (RF) deals, which were short-term transactions backed by government securities. As a broker, Harshad Mehta acted as an intermediary between banks. Through irregular use of Bank Receipts (BRs) and weaknesses in the settlement system, large sums of money that were intended for government securities transactions became available for stock market purchases.

These funds were then used to buy shares aggressively, creating strong demand and pushing stock prices sharply higher. As prices rose, more investors entered the market, further increasing momentum. The rising stock prices created an impression of exceptional opportunities, attracting additional participation and liquidity. This cycle continued as long as fresh money kept entering the market.

However, the structure depended heavily on continuous liquidity and confidence. Once irregularities in the transactions were discovered, banks and regulators tightened controls and demanded settlement of funds. The flow of money stopped, liquidity dried up, and stock prices began to fall. What had fueled one of the biggest bull runs in Indian market history quickly turned into a sharp market correction. The episode remains one of the most powerful examples of how liquidity can drive markets far beyond fundamentals, but also how quickly momentum can reverse when that liquidity disappears.

What Went Wrong?

Harshad Mehta was intelligent, influential, and deeply aware of how markets functioned but in short term but what was needed to create a long-term story he was not having idea.

 Once liquidity was tightened, the rally could no longer sustain itself.

Markets delivered one of their oldest lessons:

Liquidity can create momentum, but it cannot permanently replace fundamentals.

Fast growth in the short term is often driven by liquidity. Long term Growth, however, is driven by business performance and compounding.

From this rise and downfall

Lesson for Traders & Investors

1. Liquidity can move even weak Stocks: Even weak businesses can experience sharp rallies when liquidity enters aggressively. Traders may profit from such moves, but investors should not confuse liquidity-driven momentum with long-term value creation.
2. Exit Discipline is everything for traders: If you are trader and buying due to liquidity you must know when to exit even in loss else capital will be ruined.
3. Invest in Business that can recover: Invest only in stocks that will rise back again due to strong valuations. An important lesson is that the market did not return to 1,000 after. Genuine business growth, economic reforms, and improving investor participation remained intact. However, a substantial part of the liquidity-driven excess was removed.
4. Invest only with amount with has long term Liquidity: Don’t invest for long term based on current liquidity. If you don’t need money for next 10 years then only invest now for long term, Investors don’t leverage.
5. Stock market is a place to build huge Profits and Wealth.
