Can anyone please explain to me how spot rates are not equal to the annual coupon payments of a bond?
Say a bond is paying 8% coupons annually, how is it that the spot rate is then say 6%?
As the spot rate is supposed to be the current value of a single payment at one time in the future, so why isnt it the same as the promised coupon rate say a year from now if the coupon is paying annually?
I feel like I am fundamentally not understanding something here.
