Problem $5$: Six$-$Month Negotiable $CD$

Problem: A bank has issued a six$-$month, $$2$ million negotiable $CD$ with $a0\mathrm{.}52$ percent quoted annual interest rate. Calculate the bond equivalent yield, the EAR, the maturity amount, and the $secondary$ market yield $if$ the $CD$ price falls.

Step $1$: Bond Equivalent Yield $(BEY)$

The Bond Equivalent Yield $is$ calculated using the quoted rate and maturity period.

Formula:

BEY$=(F)x\frac{365}{360}$

Solution:

$=0\mathrm{.}52\frac{365}{360}=0\mathrm{.}5272$

Step $2$: Effective Annual Return $(EAR)$

The EAR reflects compounding over the year.

Formula:

$(1+\frac{\text{B}\text{E}\text{Y}}{365n}){?}^{(}\frac{365}{n})1$

Solution:

$==(1+\frac{0\mathrm{.}5272}{365180})\frac{{?}^{(}365)}{{?}^{180}}-1$

$=2\mathrm{.}18\%$

Step $3$: Amount Received $at$ Maturity

The maturity amount $is$ calculated using simple interest.

Formula:

Maturity Amount$=P(1+Fn360)$

$P=2,000,000$

Quoted $=0\mathrm{.}52\%$

$n=180$

$360$

Solution:

$=2,000,000(1+0\mathrm{.}52x180360)$
