Pass Certification Examination for Mutual Fund - Specialized Investment Fund Distributors Difficulty: Intermediate 2 Questions   5 min read
📌 Chapter 20.4 — Lot Size, Tick Size and Change in Contract Value for each Tick change

A regular client in your Mumbai wealth office, who typically allocates to liquid mutual funds, asks how a shift in market yields will impact their tactical position in 91-Day T-Bill futures. They are confused why the price of their futures contract moves in the opposite direction to the interest rate, and how that translates into their potential profit or loss.

As their advisor, you must bridge this gap by explaining the inverse relationship between yield and price, which is fundamental to managing risk in any debt-oriented portfolio, whether it is a standard mutual fund or a Specialized Investment Fund strategy.

In the Indian debt market, when the implied yield of a 91-Day T-Bill rises, the price of the future contract falls. Understanding this mechanism is vital because your client might be using these futures as a hedge against a rise in short-term interest rates. If you fail to explain that the yield movement is measured in basis points and that each change has a direct currency impact on their collateralized position, you risk failing your suitability assessment obligations.

You aren’t just discussing market movements; you are explaining the financial mechanics that protect their capital from volatility.

Consider an HNI client who intends to hedge a portfolio against a 25-basis-point (bps) hike in short-term rates. By knowing that the T-Bill future price effectively discounts the yield, you can demonstrate the potential mark-to-market loss on their futures position. This calculation helps the client realize that the futures hedge is a surgical tool, not a passive investment.

When you provide such clarity, you move from being a mere product distributor to a trusted advisor who understands the underlying mechanics of institutional-grade debt instruments, which is the standard expected when navigating complex investment strategies.

Ultimately, the precision of your advice reinforces your compliance posture. When a client understands the cost of a yield move, they are less likely to panic during market turbulence or complain about unforeseen losses. Your ability to translate abstract yield changes into specific rupee impacts is the hallmark of a professional who treats the client’s financial stability as the priority, ensuring they remain informed throughout the lifecycle of their investment.

Nuance

⚠️ Nuance
A common professional misconception is conflating the yield movement with the tick price. Candidates often mistake the ’tick value’ for the absolute ‘yield change’ value, forgetting that the tick value is a standardized exchange constant, whereas the yield movement is a market-driven variable. A skilled advisor must calculate the price change based on the yield delta first, then apply the contract multiplier to determine the actual financial impact, rather than simply guessing the volatility.

Check Your Understanding

Practice Question 1

An investor holds a short position in 5 lots of 91-Day T-Bill futures. If the implied yield of the T-Bill increases by 10 basis points, causing the price of the contract to drop by Rs 0.25, what is the impact on the investor’s total contract value? (Assume a face value of Rs 100 per unit and a lot size of 10,000 units).

Practice Question 2

Why is it critical for a distributor to accurately calculate the currency risk arising from yield movements for a client using T-Bill futures?
