The Surging Loan Book
The margin trading facility loan book has ballooned to an unprecedented Rs 1.16 trillion as of January 19. This figure represents a nearly 50 per cent year-on-year increase and a more than four-fold surge over the past four years. Brokers, facing regulatory shifts and curbs on derivatives, have increasingly promoted MTF as a key revenue stream.
Margin Trading Explained
Margin trading allows investors to borrow funds from their brokers to purchase securities. Investors pay only a portion of the total transaction value upfront, with the broker financing the remainder at an interest cost. This facility enables larger positions but inherently increases leverage.
Kamath's Risk Assessment
Kamath contends that risk management in MTF is more complex than in futures and options (F&O). Clients can maintain leveraged positions for months, and MTF is permitted across over 1,300 stocks, including many illiquid ones. Indian equities often show high liquidity during market upswings but liquidity 'dries up' during corrections, with minimal natural demand for selling.
Layered Leverage Amplifies Losses
He further highlighted the danger of layered leverage, where pledged shares as collateral can significantly magnify exposure. For instance, Rs 1 lakh worth of shares could back an MTF position of up to Rs 5 lakh. This amplification mechanism can magnify investor losses dramatically during market declines.
Regulatory Safeguards Under Scrutiny
While the Securities and Exchange Board of India (Sebi) has implemented caps on MTF exposure relative to broker net worth and borrowings, Kamath suggests these primarily protect the system from broker failures. They offer less protection for brokers against potential client defaults.
Looming 'Mayhem'
Kamath warned that the market has not experienced a severe downturn since MTF scaled significantly. He anticipates that when such an event occurs, it could lead to 'mayhem,' not necessarily from broker failures, but from cascading forced selling into illiquid markets, creating self-reinforcing downward spirals.
