The current price of $1 par of a zero maturing at time 2 is
$0.90. In addition, you can
contract today to purchase, at time 2, $1 par of a zero maturing at
time 3. The forward
price to pay at time 2 for this zero maturing at time 3 is $0.94.
It costs nothing today
to enter into this forward contract.
a)
What is the forward rate from time 2 to time 3?
b)
Describe transactions in the 2-year zero and the forward contract
that together
synthesize a spot purchase of $1 par of the zero maturing at time
3. (With the spot
purchase, you pay for the zero today, rather than in 2
years.)
c)
Assuming there are no arbitrage opportunities, what is the current
spot price (the
price to pay today) for $1 par of the zero maturing at time 3?
