Assume today’s 6-month forward rate is 7% and every 6 months it can increase or decrease by 1%, i.e., in 6 months the 6-month forward rate can be either 6% or 8%; and in 1 year it can be either 5%, 7%, or 9%. Assume also that currently 1-year spot rate is 7.2% and the 1.5-year spot rate is 7.3%. Like in lectures, assume that the risk-neutral probability depends on the time period but not on the exact node. Find the price of a 1-year call option with a strike price of $960 on the 1.5-year zero-coupon bond. Assume all bonds have a $1000 face value. Keep at least 5 decimal digits.

All interest rates are annual interest rates with semi-annual compounding. All coupon rates are annual rates paid semi-annually.
