The rate of return on 90-day U.S. treasury securities is 3.9% and the rate of return on 90-day U.K. risk-free securities is 5.0%. Using the spot exchange information from Table 17-1, estimate the 90-day forward exchange rate.

Using knowledge of interest rate parity, the following problem is set up.
Spot exchange rate (direct quotation) =			1.3071
Home nominal interest rate =			3.9%
Foreign nominal interest rate =			5.0%
Time to maturity on securities (in years) =			0.25

ft / (spot exchange rate)

=

[ (1+rh) / (1+rf) ]

Home periodic interest rate = ?

Foreign periodic interest rate =?

estimate the 90-day forward exchange rate =?
