Tim wants to invest in zero-coupon risk-free bonds for the next 5 years. The 5-year spot rate is 3.5%. The 3-year spot rate is 3.0%. if he purchases a 3-year zero-coupon bond (bond A) and then reinvests his proceeds in a 2-years zero-coupon bond (bond B) when bond A matures, what does he expect the spot rate to be on bond B?
