Assume the following: - Annual risk-free rate on US dollars (=4 %). - Annual risk-free rate on
Question:
Assume the following:
- Annual risk-free rate on US dollars \(=4 \%\).
- Annual risk-free rate on British pounds \(=2 \%\).
- \(\$ /\) BP spot exchange rate \(=\$1.30 / \mathrm{BP}\).
- Mean annualized logarithmic return (for \(\$ / B P\) exchange rate) \(=\mu^{\mathrm{A}}=0\).
- Annualized logarithmic return's standard deviation \(=\sigma^{\mathrm{A}}=\)0.25 .
- BP futures contract expiring in 120 days.
- The BP futures price is determined by the interest-rate-parity condition:
\[f_{0}=E_{0} e^{\left(R_{\$}-R_{B P}\right) n_{f} \Delta t}\]
Determine the following:
a. The price of a European BP futures call option with an exercise price of \(\$1.30\) and expiration of 60 days using the Black futures option model.
b. The price of a European BP futures call with an exercise price of \(\$1.30\) and expiration of 60 days using the binomial Excel program for the case of \(n=30\) subperiods of length \(\Delta t=\) \(2 / 365\).
c. The price of a European BP futures put with an exercise price of \(\$1.30\) and expiration of 60 days using the Black futures option model.
d. The price of an European BP futures put with an exercise price of \(\$1.30\) and expiration of 60 days using the binomial Excel program for the case of \(n=30\) subperiods of length \(\Delta t=\) \(2 / 365\).
