Session 5: Estimating Hurdle Rates - The Risk free Rate

New Section

In this section, the concept of a risk-free rate in finance is discussed, emphasizing its importance as a fundamental input for financial calculations and the challenges in determining an accurate risk-free rate.

Understanding the Risk-Free Rate

• A risk-free rate represents the return on a guaranteed investment and serves as a crucial starting point for calculating hurdle rates.

• The significance of the risk-free rate has grown over time, especially in current market conditions where it plays a key role in determining expected returns using models like CAPM.

• The expected return in CAPM comprises the risk-free rate as a base, beta reflecting relative risk, and an equity risk premium, highlighting the complexity involved in estimating an accurate expected return.

• Key criteria for defining a risk-free investment include zero default risk from the issuer and no reinvestment risk to ensure certainty of returns.

• Challenges arise when analyzing investments with cash flows at different time points, necessitating matching each cash flow with an appropriate duration-matched risk-free rate.

Risk-Free Rate Calculation Strategies

This section delves into strategies for calculating and applying risk-free rates effectively in financial analysis to mitigate risks associated with varying cash flow timings.

Duration Matching Approach

• For precise analysis, each cash flow ideally requires its unique duration-matched risk-free rate based on zero-coupon Treasury bonds corresponding to the cash flow period.

• "Duration matching" offers a simplified approach by aligning average durations of assets with liabilities to manage interest rate risks effectively.

• By considering weighted average durations of cash flows and selecting a comparable duration for the risk-free rate, analysts can enhance accuracy in evaluating investments despite not achieving perfection.

Practical Application of Risk-Free Rates

This segment explores practical applications of determining currency-specific risk-free rates and their impact on investment analyses across different currencies.

Currency-Specific Risk-Free Rates

• Selecting an appropriate currency-specific default-free bond with a matching maturity period can serve as an effective proxy for deriving a reliable currency-specific risk-free rate.

Risk-Free Rate and Currency Analysis

In this section, the speaker discusses the concept of risk-free rates in different currencies and how to determine them based on government bond rates and default risks.

Risk-Free Rate in Euros

• To calculate a risk-free rate in euros for Deutsche bank hurdled rate, one needs to consider 10-year government bond rates denominated in euros. Different countries have varying rates due to perceived default risks.

• The market perceives more default risk in countries like Greece, Spain, and Portugal compared to Germany. Therefore, the 10-year German bond rate (1.75%) is suggested as a close approximation of a risk-free rate in euros.

Risk-Free Rates in Different Currencies

• For currencies with default risk like Indian Rupee, Brazilian Real, or Chinese Yuan, determining a risk-free rate involves adjusting the government bond rate by subtracting the estimated default spread.

• In the case of Indian Rupee, if the government bond rate is 8.82% with an estimated default spread of 2.25%, the resulting risk-free rate would be calculated as 6.57%.

Currency Analysis and Alternatives

This part delves into strategies for dealing with currency considerations when analyzing investments and offers alternatives to using local currency risk-free rates.

Local Currency Risk-Free Rates

• One approach is to stick with the local currency and adjust for default risk by netting out from the government bond rate. Another method involves incorporating expected inflation and interest rates to derive a synthetic risk-free rate.

• Some analysts opt for conducting analyses in U.S. dollars instead of local currencies due to complexity or uncertainty surrounding local currency risk-free rates.

Alternative Currency Choices

• Shifting analysis to a different currency can simplify calculations but introduces exchange rate considerations that impact cash flows conversion.

Real Terms Analysis

• An alternative strategy involves conducting analyses in real terms by removing inflation from cash flows and utilizing real risk-free rates such as TIPS (Treasury Inflation Index Bond) rates for discounting purposes.

Analysis of Default Spreads and Risk-Free Rates

In this section, the speaker discusses the importance of determining default spreads and risk-free rates in various currencies for financial analysis.

Ways to Obtain Default Spread

• To calculate default spreads accurately, it is crucial to decide early on the currency or real analyses being conducted. This decision influences obtaining a risk-free rate in that specific currency.

Obtaining Default Spread: Market-Based Measures

• There are three primary ways to acquire a default spread. These methods may vary in applicability depending on the circumstances:

• Utilize market-based measures such as government bonds denominated in foreign currencies like U.S. dollars to derive default spreads.

• Another market-based measure involves referencing the Credit Default Swap (CDS) market, where sovereign CDS spreads provide insights into perceived default risks.

Using Sovereign Ratings for Default Spreads

• When market-based measures are unavailable, sovereign ratings can serve as a valuable alternative for determining default spreads.

• By creating lookup tables with average spreads corresponding to different ratings classes, one can estimate typical default spreads based on sovereign ratings.

Risk-Free Rates Across Currencies

The discussion shifts towards understanding risk-free rates across different currencies and their implications for financial analysis.

Variability of Risk-Free Rates

• Risk-free rates exhibit significant variability across currencies due to differences in inflation levels.

• High inflation currencies tend to have higher risk-free rates, while low inflation currencies typically offer lower risk-free rates.

Impact of Currency Choice on Cash Flows

• Selecting a currency with low inflation for discount rates necessitates cash flows also being denominated in that same low inflation currency.

• Transitioning from a low inflation currency to a high inflation one may not confer cost advantages due to offsetting effects related to inflation disparities.
