Problem $6$: Market Value $of$ a Negotiable $CD$

Problem:

You have just purchased a three$-$month, $$500,000$ negotiable $CD,$ which will pay $a5\mathrm{.}5$ percent

annual interest rate. $If$ the market rate rises $to6$ percent, what $is$ its current market value? $If$ the

market rate falls $to5\mathrm{.}25$ percent, what $is$ its current market value?

Given:

$Fv$: $500,000$

$R$: $6\%$

$n=90$ days

$360$

Step $1$: Market Value $if$ Rate Rises $to6\%$

Use the Present Value Formula $to$ adjust for changes $in$ the market rate.

Formula:

$PV=\frac{FV}{1+(\frac{\text{R}\text{a}\text{t}\text{e}\text{D}\text{a}\text{v}\text{s}}{360})}$

Solution

$PV=\frac{500,000}{1+(\frac{0\mathrm{.}0690}{360})}$

$=$$$492,610\mathrm{.}84$

Step $1b$: Market Value $if$ rate falls $5\mathrm{.}25\%$

Formula:

$PV=\frac{FV}{1+(\frac{\text{R}\text{a}\text{t}\text{e}\text{D}\text{a}\text{v}\text{s}}{360})}$

Solution:

$PV=\frac{500,000}{1+(\frac{0\mathrm{.}052590}{300})}$

$=$$$493,522$
