Korean Market Rout: Nithin Kamath Warns of Margin Funding Risks in India

Zerodha CEO Nithin Kamath warns that the sharp boom-and-bust in South Korea's stock market highlights risks from rising margin funding in India. He describes the Korean market rout as his "biggest nightmare," noting that Zerodha's Rs 9,000 crore MTF book is its biggest risk since 2010. Nearly half of the firm's MTF exposure is in non-F&O stocks, which can hit lower circuits and make exits difficult during declines. Kamath cautions that a steep correction could trigger forced selling and a self-reinforcing loop, especially in small- and mid-cap stocks.

Korean market rout highlights risks of rising margin funding in India: Zerodha's Nithin Kamath

New Delhi, July 29

Zerodha Founder and CEO Nithin Kamath on Wednesday said the sharp boom-and-bust witnessed in South Korea's stock market has highlighted the risks associated with rising margin funding in India, warning that a steep market correction could trigger widespread selling in small- and mid-cap stocks.

In a post on X, Kamath described the developments in the Korean market as his "biggest nightmare" as a broker, saying the rapid growth in Margin Trading Facility (MTF) books across the industry has significantly increased market risks.

"My biggest nightmare as a broker is what's happening in the Korean markets right now. The source of my nightmare is the way our MTF book has been growing along with the industry as a whole," Kamath said.

He added that Zerodha's Rs 9,000-crore MTF book is "by far the biggest risk we have taken since we started in 2010."

According to Kamath, the key concern lies in the composition of the firm's MTF portfolio, with nearly half the exposure concentrated in non-F&O stocks that can hit lower circuits for multiple sessions, making exits difficult during sharp market declines.

Explaining the risks, Kamath said a strong market rally often leads to an increase in leverage as the value of pledged collateral rises, allowing investors to borrow more.

However, when markets reverse, falling collateral values trigger margin calls, resulting in forced selling that can accelerate market declines.

"When the markets fall, things get really ugly. The first leg of selling tends to be small, but as collateral and margin values drop, margin calls increase, leading to forced selling... this downside move becomes a self-reinforcing loop until things stabilize," he said.

The comments come after South Korea's benchmark KOSPI index has witnessed extreme volatility in recent months. After surging more than 60 per cent between April and June, the index has corrected sharply, falling over 35 per cent in the past month amid heavy selling.

The benchmark is currently trading at around 5,663, with the sharp reversal drawing attention to the risks associated with leverage-driven rallies and forced deleveraging during market downturns.

Kamath noted that India's MTF market has expanded rapidly only over the past three to four years and has not yet experienced a sharp correction comparable to the one seen in South Korea since the COVID-19 pandemic.

He cautioned that although MTF remains a relatively small proportion of India's overall market capitalisation, a steep decline in domestic equities could result in severe selling pressure across many small- and mid-cap stocks, as brokers currently offer MTF on nearly 1,500 stocks.

Kamath, however, credited market regulator SEBI for preventing excessive leverage in India.

"Luckily, thanks to SEBI, we've avoided the worst excesses that typically arise from unchecked leverage," he said.

Finally someone speaking sense. The FOMO in the market right now is unreal. Everyone is taking loans to invest in penny stocks and small caps. Kamath's warning about non-F&O stocks hitting lower circuits for multiple sessions is scary. Imagine being stuck in a stock that falls 20% in one day and you can't sell.

Respect to Nithin for admitting this is his biggest risk. But honestly, Zerodha and other brokers are also at fault here - they offer MTF so easily. A 9,000 crore MTF book is massive. The industry should have learned from the Harshad Mehta and Ketan Parekh days - leverage always ends badly for retail investors.

Great perspective from Kamath. But I think he is also trying to manage expectations because Zerodha's own MTF expansion. Yes, SEBI has done well to cap leverage, but brokers are finding ways to offer more margin through pledge-based lending. The Korean situation is a perfect example of what happens when leverage spirals out of control.

I work in a small broking firm and can confirm MTF is growing like crazy. Our top clients are all using maximum margin to buy midcaps. Everyone thinks they are genius until the market turns. Kamath's nightmare is real. Small and midcap stocks will get hammered if there's even a 5% correction. 😬

Kamath is one of the most honest voices in Indian finance. He could easily have kept quiet, but he chose to warn investors
