📌 Chapter 8.7 — MARGIN TRADING

Picture this: a high-net-worth client with a long-standing relationship calls your dealing desk, requesting a massive jump in their Margin Trading Facility (MTF) to accumulate a specific mid-cap stock. As the middle-office professional monitoring the firm’s risk, your first instinct is to check the exposure ledger before even considering the trade. You know that while the firm might have an overall MTF capacity, the regulator mandates strict boundaries on how much of that facility can be tied up in a single relationship to prevent systemic concentration risk.

In the Indian markets, the regulator imposes a ceiling where a broker’s exposure to a single client cannot exceed 10% of the maximum allowable MTF facility. If your firm’s total authorized margin funding capacity is Rs. 50 Crores, then no single client—regardless of their creditworthiness or assets under management—can be funded beyond Rs. 5 Crores.

This rule acts as a fundamental circuit breaker in your firm’s operations, ensuring that the default of one large client does not cripple the firm’s net worth or trigger a liquidity crisis that impacts other clients.

Operationalizing this requirement goes beyond a simple arithmetic check. Your risk management system must flag any order that pushes a client toward this 10% threshold in real-time, preventing the trade from flowing through to the exchange. If you allow the breach, you are not just failing a compliance audit; you are exposing the firm’s capital adequacy to unnecessary volatility.

When dealing with MTF, you must treat the ledger as a dynamic document where daily MTM fluctuations can inadvertently push a client over their limit as their position value changes, even if no new trades are executed.

Ultimately, this limit is your safeguard against the ‘all-eggs-in-one-basket’ scenario. By enforcing these caps, you ensure that the firm maintains a diversified risk profile, which is essential when dealing with leveraged positions in volatile securities. Always prioritize these hard limits over client pressure, as the regulatory consequences for exceeding concentration caps are far more severe than the temporary frustration of an aggressive trader.

Nuance

⚠️ Nuance
A common mistake candidates make is confusing the broker’s aggregate borrowing limit—which is 5 times the net worth—with the individual client’s exposure cap. The 10% limit applies to the ‘maximum allowable facility’ the broker has set for themselves, not the broker’s entire net worth or total capital. Always clarify whether the question refers to firm-wide leverage or individual client concentration, as mixing these leads to errors in calculating risk thresholds.

Check Your Understanding

Practice Question 1

A broker has a maximum allowable MTF facility of Rs. 20 Crores. What is the maximum exposure the broker can legally maintain for a single client under these regulations?

Practice Question 2

In the context of internal risk controls for MTF, why is it critical for the middle office to monitor the 10% single-client exposure limit daily?
