Answer:
$976.90 will be the new price if interest rates increase to 8.5 percent.
Explanation:
YTM = 8%
Change in interest rate = (8.5% - 8%) = 0.5% (Increase of 0.5% )
%Change In Price of Bond = -Duration/(1+YTM) X Change in Rate
= -4.99/(1+0.08) X 0.5%
= -2.310%
There will be a decrease of 2.310% in Bond Price
New Bond Price = 1000 - (1000 X 2.310%)
= 1000 - 23.10
= $976.90
