A man in India haunted the stock market in the early 1990s by taking advantage of banking regulations. Banks were required to maintain a certain percentage of deposits in government bonds, known as the Statutory Liquidity Ratio (SLR). Each day, banks had to submit reports detailing their balances and verifying sufficient investment in government bonds. This man would borrow money from multiple banks each day, using the funds from one bank to repay loans from others. By keeping the cycle going, he effectively retained control over the money from the first bank for the whole week.
