An investor purchased a "par bond" for $500 with the principal $500. Over n = 6 years the bond will pay 2% coupon annually. Find the IRR of the cash flow stream (also called Yield to Maturity). Note: The bond has the following cash flow stream: at time zero payment $500 is made; for 6 years, at the end of each year the coupon payment (2/100)*500 is made; also at the end of year 6 the principal $500 is paid in addition to the last coupon.

2.0%

Explanation:

Coupon received annually = $500*2% = $10

We have the cash flow from year 0 to year 6 as below:

Year 0($500)

Year 1$10  

Year 2$10  

Year 3$10  

Year 4$10  

Year 5$10  

Year 6$510   (Principal $500 & coupon $10)

IRR (internal rate of return) whereas  the present value of all cash flow is nil

It is very difficult to calculate IRR manually, but easily in excel = IRR(-500,10,10,10,10,10,510) = 2%

Please see excel attached

due to the changes the federal reserve is making the unused reserves will impact the economy by them facing inflation. inflation is definfed as the increase in pricing of a good or service but the decline of the value of money used for purchasing those items. when the economy has a high inflation rate, they are subject to money loss and hurt on the economy.
