PV = FV / (1+i) ^ tPV = FV / (1+i) ^ tA dollar paid to you 1 year from now is A dollar paid to you 1 year from now is
worth less than one dollar paid to you worth less than one dollar paid to you todaytoday
Ex. PV of $250 paid in 2 years, i=15%Ex. PV of $250 paid in 2 years, i=15%PV = 250 / (1 + .15) ^ 2PV = 250 / (1 + .15) ^ 2 = $189.04= $189.04

Central Banks and Interest Central Banks and Interest RatesRates
Very important in determining interest Very important in determining interest ratesrates
Central banks determine lending rates and Central banks determine lending rates and heavily influence market interest ratesheavily influence market interest rates
Lending rate is the rate that the central Lending rate is the rate that the central bank will lend to other banks, thereby bank will lend to other banks, thereby insuring that all lending rates (inter-bank or insuring that all lending rates (inter-bank or otherwise) are above this rateotherwise) are above this rate

Rate of return on a bond not necessarily the yield to Rate of return on a bond not necessarily the yield to maturity of the bondmaturity of the bond
Rate of return is dependant on behaviour of market Rate of return is dependant on behaviour of market interest rates over the holding period of the bondinterest rates over the holding period of the bond
If a bond is held for its entire life, then yield to maturity is If a bond is held for its entire life, then yield to maturity is equal to the return of the bondequal to the return of the bond

Q. What is the rate of return on a bond Q. What is the rate of return on a bond bought for $988 and sold one year later for bought for $988 and sold one year later for $1200? The coupon rate is 5%, and face $1200? The coupon rate is 5%, and face value is $1000.value is $1000.
A. (C / Pt) + (Pt+1 – Pt) / PtA. (C / Pt) + (Pt+1 – Pt) / Pt
= ( 50 / 988) + (1200 – 988) / 988= ( 50 / 988) + (1200 – 988) / 988
