Answer:
less desirable to other investors
Explanation:
<u>Given</u>: Current fixed coupon rate 5%
Market rate of interest 5%
New Market Rate of Interest 6%
Value of a bond is inversely related to economy interest rate or the yield to maturity (YTM). Value of a bond is expressed by the following equation:

wherein, C = Coupon rate of interest
YTM = Market Rate of Interest or interest rate in the economy or investor's expectation
n= Years to maturity
RV = Redemption value
In the given case, C = YTM i.e par value bond. When ytm rises to 6%, the value of the bond shall fall making such a bond less attractive since it represents lower coupon payments than investor expectations.
Thus, now the bond would be less desirable to other investors.
