MTF Hits Record ₹1.27 Lakh Crore as Investors Borrow Heavily to Buy Stocks; Is a Leverage Risk Building?

India's Margin Trading Facility (MTF) book has surged to an all-time high of ₹1.27 lakh crore in May 2026, highlighting the growing use of borrowed money in the stock market. According to CareEdge Ratings, the industry's average MTF book jumped 65.4% year-on-year and rose 11.1% month-on-month, despite flat market trading volumes and heavy foreign investor selling.

The sharp rise in leveraged investing is now raising concerns about potential risks if markets witness a sudden correction.

What is Margin Trading Facility (MTF)?

Margin Trading Facility (MTF) allows investors to buy stocks by paying only a portion of the total value while borrowing the remaining amount from their broker.

For example:

• Investor invests ₹25
• Broker funds ₹75
• Total stock purchase becomes ₹100

While MTF can amplify profits during rising markets, it can also magnify losses when stock prices fall.

MTF Explained

Particulars	Example
Investor Capital	₹25
Broker Funding	₹75
Total Investment	₹100
Benefit	Higher Buying Power
Risk	Higher Losses

Why is MTF Rising So Rapidly?

Several factors are driving the surge in margin-funded stock purchases:

• Strong retail participation
• Bullish sentiment in equities
• Easy access to leverage
• Competition among brokers
• Growing interest in cash market investing

Despite foreign investors pulling out nearly ₹2.8 lakh crore from Indian equities this year, retail investors continue increasing their exposure through borrowed funds.

Why Experts Are Worried

The biggest concern is that a large portion of MTF exposure is concentrated in mid-cap and small-cap stocks, many of which have lower liquidity.

According to industry estimates:

• Nearly 50% of the MTF book is linked to non-F&O stocks.
• Sharp market declines can trigger margin calls.
• Forced selling can accelerate price falls.
• Brokers may face losses if stocks hit lower circuits.

This creates a potential risk for both investors and brokerage firms.

Zerodha CEO Nithin Kamath Flags Risks

Nithin Kamath, Founder and CEO of Zerodha, recently highlighted concerns around the rapid growth of MTF books across the brokerage industry.

According to Kamath:

• Leverage appears to be growing despite stagnant markets.
• Risk increases significantly when investors borrow against stocks.
• Small-cap and mid-cap stocks could become vulnerable during market corrections.
• Excessive leverage can create systemic risks for the broader ecosystem.

Could MTF Become a Market Risk?

MTF itself is not dangerous when used responsibly. However, excessive leverage can amplify volatility during market downturns.

Key Risks

Risk Factor	Impact
Margin Calls	Negative
Forced Selling	Negative
Liquidity Crunch	Negative
Broker Exposure	Negative
Market Volatility	Negative

If markets remain stable, leverage may continue supporting buying activity. However, a sharp correction could trigger widespread selling pressure.

RBI Rules Could Impact Market Liquidity

Market participants are also closely watching upcoming RBI regulatory changes, scheduled to come into effect in July 2026.

Analysts believe the new framework could:

• Affect market liquidity
• Impact trading volumes
• Influence leveraged positions
• Test investor risk appetite

The coming months may provide a clearer picture of whether current leverage levels remain sustainable.

Key Highlights

• MTF book hits record ₹1.27 lakh crore
• Growth of 65.4% year-on-year
• Retail investors increasing leveraged bets
• Nearly 50% exposure linked to non-F&O stocks
• Experts warn of margin call risks
• Nithin Kamath raises concerns over rising leverage
• RBI's new regulations to take effect in July 2026
• Market participants closely watching liquidity trends

Conclusion

The record rise in India's MTF book reflects growing confidence among retail investors, but it also highlights the increasing role of leverage in the stock market. While margin funding can boost returns during bull markets, it can quickly become a source of risk during corrections. With MTF exposure now at ₹1.27 lakh crore and fresh RBI regulations approaching, investors and brokers alike will be watching closely to see whether leverage continues to fuel the rally or becomes a vulnerability for the market.
