📌 Chapter 4.12 — Criteria to evaluate loans

Imagine you are drafting a debt-servicing analysis for a corporate client in India who is considering a large expansion project. You are reviewing two loan term sheets: one linked to a fixed-rate structure and another indexed to an external benchmark like the repo rate plus a spread. As a research analyst, your primary concern is not just the current cost of capital, but how the volatility of the interest rate cycle could erode the client’s debt service coverage ratio (DSCR).

Modeling this requires a sensitivity analysis that assumes multiple rate-hike scenarios to ensure the firm remains solvent even when the Reserve Bank of India (RBI) initiates a tightening cycle.

Floating rate loans are inherently sensitive to monetary policy shifts. When a central bank increases interest rates to curb inflation, the cost of borrowing for firms on floating rate structures rises almost immediately, depending on the reset frequency of their specific benchmark. Unlike fixed-rate debt, which acts as an insurance policy against rising costs, floating rate debt forces the borrower to absorb the full impact of market volatility.

For an analyst, this means the ’effective cost’ of a floating rate loan is dynamic; it is a moving target that fluctuates alongside the macro environment.

Consider a scenario where a mid-sized manufacturing company holds a term loan tied to the MCLR (Marginal Cost of Funds based Lending Rate). During a cycle of rising repo rates, the bank will eventually reset the MCLR upwards, increasing the company’s interest outflow. If the company’s operating margins are thin, this incremental cost can suddenly exhaust cash reserves, leading to a liquidity crunch despite the firm’s core operations remaining profitable.

The analyst’s role is to stress-test the borrower’s balance sheet against these spikes, ensuring the debt structure does not become a catalyst for insolvency.

Ultimately, your recommendation regarding a client’s liability management should be informed by their appetite for risk and their ability to hedge against these rate fluctuations. While floating rate loans often start with lower ’teaser’ or current rates compared to fixed-rate alternatives, they carry significant ’tail risk’ during periods of economic tightening. A prudent professional must quantify this exposure by building a ‘worst-case’ interest rate scenario into the valuation model, rather than relying solely on the current, favorable rate environment.

By evaluating the spread and the reset period, you provide the client with a clearer picture of their long-term financial resilience. [^1] [^2]

Nuance

⚠️ Nuance
A common professional misconception is that floating rate loans are always ‘cheaper’ simply because the initial rate is lower than the fixed-rate equivalent. Candidates often ignore the ‘convexity’ of the borrower’s risk; as interest rates rise, the debt service cost increases, but the value of the firm’s assets may simultaneously decline due to higher discount rates. A sophisticated analyst must understand that the ‘cheapness’ is actually a premium paid by the borrower for the lender’s protection against market risk. Never assume the current rate represents the lifetime cost of the debt without conducting an interest rate stress test.

Practice Question 1

A firm has a 5-year loan with a floating interest rate reset annually based on the repo rate. If the Reserve Bank of India increases the repo rate by 75 basis points in an environment of rising inflation, which of the following is the most immediate consequence for the borrower?

Practice Question 2

When conducting a sensitivity analysis on a floating rate loan, why should an analyst prioritize the ‘reset frequency’ of the benchmark?
