Using Hard Currency Credit Calculator: $10-$year US Treasury yields $2\mathrm{.}75\%.$ Benin sovereign credit spread is $2\mathrm{.}50\%$ above US Treasury. Benin quasi$-$sovereign credit spread is $\mathrm{.}50\%$ above Benin$$s sovereign spread. Benin BigBank, a private company, has a credit spread $\mathrm{.}75\%$ higher than the Benin quasi$-$sovereign spread. Benin BigBank, a private company, has a $10-$year US$ bond with an annual coupon of $8\mathrm{.}5\%.$ Imagine that US Treasury yields immediately rise to $3\mathrm{.}00\%$ and the Benin sovereign and quasi$-$sovereign spreads do not change. If Benin BigBank$$s spread widens to $\mathrm{.}95\%$ above the quasi$-$sovereign, what gain or loss should be made on $$100$ of Benin BigBank$$s $10-$year bond?
