The New York buyers are selling some lucky retirees a $1,000 bond
that pays 4%, but when interest rates rise, that bond price drops. If
interest rates went from 4% to 8% then that bond drops from $1,000 to
$500.
Now if interest rates rise, and you go into a recession, that bond
will be worth $350. The best part is Goldman Sachs gets fees for the
bond float, the bond sale, and the bond resale.
