The investment company JPyorgen is buying ten loans from a retail bank. All ten loans have the same principal of $400,000, the same interest rate/yield of 5% (annualized), and the same maturity of 30 years. In a loan, principal plus interest rates are paid on a monthly basis. 1. What is the aggregate monthly loan payment from the 10 bonds? 2. Imagine that these loans are sold to JPyorgen for $380,000 each. What is the change in yields under the new bond price? Hint: Use command rate in Excel. 3. What is the duration, in years, of the aggregate asset/bond purchased by JPyorgen? 4. How should the loan price react to an increase in interest rates of 3% from the original 5%
