4. Another bank purchased 30 million fixed-rate, euro-denominated notes issued by a high-grade company. The 0.55% note matured in one year and was purchased at par. The bank entered into a 30 million, euro-denominated interest rate swap with a maturity of one year. The fixed-pay interest rate swap was then priced at the ask rate of 0.60% (pay 0.60% and receive six-month Euribor). How did the swap change the yield and repricing characteristics of the investment? The bank could have purchased similar credit quality floating-rate investments to yield six-month Euribor flat (i.e., no spread). Did the bank earn the best rate of return for similar credit quality investments? 4. Another bank purchased 30 million fixed-rate, euro-denominated notes issued by a high-grade company.
