Mr. Peters also learns that the three-month forward rates for the pound and the euro versus the US dollar are $1.37/1 and $1.20/1, respectively. The banker offers to set up a forward hedge for selling the euro receivable for pound sterling based on the / cross-forward exchange rate implicit in the forward rates against the US dollar.
