📌 Chapter 2.2 — Calculate the following

Imagine you are an analyst at a Mumbai-based wealth management firm, reviewing two client portfolios for a high-net-worth individual. One portfolio holds traditional, fixed-rate government bonds, while the other features floating-rate debentures linked to the Mumbai Interbank Outright Rate (MIBOR). As the Reserve Bank of India (RBI) signals a potential repo rate hike to combat inflationary pressures, you must determine how these two instruments will behave.

Relying solely on the coupon rate would be a critical error; the real work lies in assessing how each asset’s price sensitivity—or duration—responds to changing market conditions.

Risk assessment is fundamentally about quantifying uncertainty regarding future cash flows. In fixed-income securities, interest rate risk is the primary concern: when market rates rise, the present value of fixed future cash flows declines, leading to capital depreciation. Conversely, floating-rate instruments offer a hedge against this specific risk because their coupons adjust periodically to match prevailing market rates. However, this feature introduces basis risk, where the spread between the reference rate and the actual market yield may widen, potentially leading to underperformance compared to inflation or alternative benchmarks.

To effectively compare these risks, you must look beyond the nominal yield. Consider a scenario where an investor moves capital from a long-term fixed deposit into a series of floating-rate corporate bonds. While the floating-rate option provides protection against rising rates, it exposes the investor to credit spread volatility, as corporate issuers may face different liquidity constraints than the sovereign. Your valuation model must incorporate these risk premiums; otherwise, you risk misrepresenting the stability of the client’s future retirement income.

Ultimately, a professional recommendation hinges on the investor’s risk appetite and liquidity needs. If your client requires absolute certainty of cash flow for a specific liability, fixed-income instruments remain the standard, provided the maturity aligns with the liability timeline. If the objective is to participate in rising interest environments without suffering the price volatility of long-duration bonds, floating-rate instruments are superior. Evaluating these risks is not merely a mathematical exercise but an exercise in predicting the economic environment and aligning asset behavior with the client’s financial goals.

Nuance

⚠️ Nuance
Candidates often erroneously assume that floating-rate instruments are ‘risk-free’ regarding interest rate movements. While they do mitigate the price-decline risk associated with rising rates, they remain highly sensitive to credit risk—the risk that the issuer’s default spread might increase. An astute analyst must distinguish between interest rate risk, which is curtailed by floating coupons, and credit risk, which remains fully present regardless of the coupon structure.

Check Your Understanding

Practice Question 1

An analyst is evaluating a portfolio of corporate bonds with coupons that reset every six months based on the prevailing MIBOR. If the Reserve Bank of India increases the repo rate, what is the primary expected impact on these bonds compared to fixed-rate bonds of similar duration?

Practice Question 2

Which of the following scenarios describes the greatest risk for an investor holding a floating-rate note linked to a commercial bank’s lending rate?
