The assignment involves analyzing treasury bond yields to determine discount factors, bond prices, and forward rates, along with an evaluation of the market’s predictive accuracy regarding future interest rates. This comprehensive analysis extends over several interconnected steps, demanding precise calculations, interpretations, and graphical representation.

Introduction

Understanding the relationship between bond yields, discount factors, and forward rates is fundamental for financial analysts and investors. Yield curves, representing interest rates for different maturities, reflect market expectations about future interest rates, inflation, and monetary policy. This report outlines a detailed approach to estimating discount factors at various maturities, calculating bond prices, deriving forward rates, and assessing the market's predictive accuracy based on the provided data for December 2007 and December 2008.

1. Estimating Discount Factors Using Linear Interpolation

The first step involves calculating discount factors for maturities t = 0.5, 1.0, 1.5, ..., 10.0 years on both December 2007 and December 2008. Given discrete yield points, linear interpolation offers a straightforward method for estimating yields for intermediate maturities. The yield-to-maturity data is given explicitly at specific maturities, thus allowing the construction of a continuous yield curve for estimation purposes.

The yield-to-maturity, expressed semi-annually, can be converted into a discount factor using the formula:

D(t) = 1 / (1 + y/2)^{2t}

where y is the semi-annual yield expressed as a decimal. Interpolating yields between known maturities involves identifying the two bounding data points and applying the linear interpolation formula:

y(t) = y1 + (y2 - y1) * (t - T1) / (T2 - T1)

with T1 and T2 being the known maturities bracketing t, and y1 and y2 the corresponding yields.

2. Calculating Bond Prices

The second task is to compute the price of a 3-year semi-annual coupon bond with face value 100 and a 3% annual coupon rate, given the derived discount factors. The bond pays semi-annual coupons of 1.5 (since 3% annually on face value of 100), with cash flows occurring at 0.5-year intervals for 3 years, totaling 6 payments.

The bond price at each date is obtained by summing the present values of all future cash flows:

P = Σ [C / (1 + y_i/2)^{2t_i}] + FV / (1 + y_{maturity}/2)^{2maturity}

where C is the semi-annual coupon, y_i is the yield corresponding to maturity t_i (interpolated), and FV is the face value.

3. Deriving Forward Rates

Forward rates for periods f(t, t + 0.5) are derived from the discount factors as follows:

(1 + z_{t + 0.5}/2)^{t + 0.5} = (1 + z_t/2)^t * (1 + f(t, t + 0.5)/2)^{0.5}

which simplifies to:

f(t, t + 0.5) = 2 * [(D(t)/D(t + 0.5))^{1/0.5} - 1]

The calculations are performed for each t from 0.5 to 9.5 years, providing insights into market expectations for short-term interest rates.

4. Graphical Analysis of Market Predictions

Using the derived forward rates and the historical data on spot rates at various dates, a graph visualizes the evolution of expectations over time. Comparing the predicted forward rates with actual subsequent spot rates helps assess the accuracy of market predictions. Trends such as convergence or divergence indicate market sentiment and the efficacy of forward rates as predictors.

5. Evaluation of Forward Rates as Predictors

While forward rates encapsulate market expectations, their reliability in predicting future interest rates is subject to debate. The efficient market hypothesis suggests that forward rates incorporate all available information. However, factors such as risk premiums, liquidity effects, and macroeconomic shocks mean forward rates often deviate from actual future rates. Empirical studies often find forward rates to be unbiased but not precise predictors, emphasizing their utility as indicators rather than perfect forecasts.

Conclusion

This analysis demonstrates that estimation of discount factors and forward rates from market yields involves careful interpolation and application of fundamental financial formulas. While the market-derived forward rates provide useful insights, they are not infallible predictors of future interest rates due to embedded risk premiums and macroeconomic uncertainties. The graphical comparison with actual historical rates underscores the strengths and limitations of using forward rates as predictive tools, highlighting the dynamic nature of interest rate expectations in financial markets.
