📌 Chapter 2.2 — Product Definitions / Terminology

Imagine you are calibrating the risk-free rate component for your Weighted Average Cost of Capital (WACC) model to value a blue-chip infrastructure company. You instinctively reach for the yield on government securities, but you pause: do you use the yield on a 91-day Treasury Bill or a 10-year Government of India bond? In the Indian market, misidentifying the maturity profile of these ‘Gilt’ instruments can lead to significant errors in your discount rate, effectively skewing the valuation of long-term projects.

Treasury Bills (T-Bills) are short-term debt obligations issued by the Government of India, typically maturing in 91, 182, or 364 days. Because they are issued at a discount to face value and redeemed at par, they do not pay explicit interest coupons; instead, the return is the difference between the purchase price and the redemption value. As a research analyst, you view T-Bills primarily as a tool for liquidity management.

They serve as a proxy for the ’near-term’ risk-free rate and are sensitive to immediate shifts in the Reserve Bank of India’s (RBI) monetary policy, such as changes in the repo rate.

In contrast, Dated Government Securities (G-Secs) represent the long-term borrowing arm of the government, often issued with maturities ranging from 5 to 40 years. Unlike T-Bills, these instruments pay semi-annual coupons, providing a steady cash flow that allows investors to lock in interest rates over extended horizons. When you analyze a company’s long-term capital structure, you look to these instruments to derive the term premium—the extra yield investors demand for holding long-duration assets.

Consider a case where the yield curve is inverted; short-term T-Bill yields exceed 10-year bond yields. If you blindly apply a short-term T-Bill rate to discount a 20-year cash flow projection, you will artificially inflate the discount rate, leading to an undervalued stock recommendation. A prudent analyst recognizes that T-Bills reflect the ‘cost of cash’ in the immediate future, whereas Dated G-Secs reflect the ‘cost of capital’ over the life of an investment.

Mastering this distinction ensures that your financial models accurately capture the time value of money and the prevailing interest rate risk.


Nuance

⚠️ Nuance
A common pitfall for candidates is the assumption that the ‘risk-free rate’ is a monolithic number applicable to all models. In reality, the ‘risk-free’ nature of a Gilt instrument applies to credit risk—the government will not default—but not to market risk. Candidates often fail to account for duration risk, erroneously believing that because a T-Bill is ‘risk-free,’ its yield is the only benchmark one should use for all valuation timeframes. Always match the maturity of your risk-free proxy to the duration of the asset you are valuing.
