India’s stock market is drawing comparisons with South Korea’s past leverage excesses, as a growing share of retail investors borrow money to buy shares. The concern is not just the amount of debt being taken on, but the speed at which it has expanded while stock valuations are already seen as stretched.
At the center of the issue are brokers that have been extending larger sums to individual traders. As competition intensifies, especially among newer brokerage platforms, easy access to margin funding appears to be encouraging more risk-taking from small investors who may be chasing rising prices.
That combination can create broader market fragility. When leverage builds quickly, a market can look strong on the way up, but sudden price declines may force investors to sell, worsening volatility. South Korea is presented as a warning sign for what can happen when debt-fueled retail participation grows too fast.
For India, the worry is that a retail-driven rally supported by borrowed money could become a source of systemic stress if sentiment turns. The parallel with Korea highlights how rapidly expanding margin debt can move from a trading tool to a market vulnerability when valuations are high and brokers keep pushing credit.
