Please do not forget to show swaps graphically as said. Otherwise I will not become a full solution. Thank you.

Companies A and B face the following interest rates: Assume that A wants to borrow U.S. dollars at a floating rate of interest and B wants to borrow British Pounds at a fixed rate of interest. A financial institution is planning to arrange a swap and requires a 20-basis-point spread to provide that service.

(b) If the swap is equally attractive to A and B, and the currency exchange risk is on company B, what possible rates of interest will A and B can end up paying? Show the swap graphically
