Zerodha founder and CEO Nithin Kamath has raised concerns over what he describes as a growing vulnerability within India’s equity markets, cautioning that the rapid expansion of margin trading could worsen the impact of any future market downturn. In a post shared on X, Kamath highlighted how the margin trading facility (MTF), which allows investors to buy shares by borrowing funds from brokers, has surged dramatically in recent years. According to him, the size of MTF exposure has grown nearly five times in the past four years and now exceeds Rs 1.10 lakh crore. Shift From Derivatives To Cash Market LeverageKamath pointed out that this sharp rise has been particularly noticeable after regulators increased margin requirements and securities transaction tax (STT) in derivatives trading.
