THE BOND MARKET Frederick University 2014
The Bond Market • Bond supply • Bond demand • Bond market equilibrium
Bond supply • bond issuers/ borrowers • look at Qs as a function of price, yield
Bond supply • lower bond prices • higher bond yields • more expensive to borrow • lower Qs of bonds • so bond supply slopes up with price
S Bond price Q of bonds
Bond Demand • bond buyers/ lenders/ savers • look at Qd as a function of bond price/yield
Bond yield Qd of bonds bond demand slopes down with respect to price price of bond Qd of bonds
D Bond price Quantity of bonds
Changes in bond price/yield • Move along the bond demand curve • What shifts bond demand?
Wealth • Higher wealth increases asset demand • Bond demand increases • Bond demand shifts right
P D D Qd
a change in expected inflation • rising inflation decreases real return inflation expected to demand for bonds (shift left)
a change in exp. interest rates • rising interest rates decrease value of existing bonds demand for bonds (shift left) int. rates expected to
a change in the risk of bonds relative to other assets demand for bonds (shift left) relative risk of bonds
a change in liquidity of bonds relative to other assets relative liquidity of bonds demand for bonds (shift rt.)
Bond supply • Changes in bond price/yield • Move along the bond supply curve • What shifts bond supply?
Shifts in bond supply • Change in government borrowing • Increase in government borrowing • Increase in bond supply • Bond supply shifts right
S S’ P Qs
a change in business conditions • affects incentives to expand production supply of bonds (shift rt.) exp. profits • exp. economic expansion shifts bond supply rt.
a change in expected inflation • rising inflation decreases real cost of borrowing supply of bonds (shift rt.) exp. inflation
Bond market equilibrium • changes when bond demand shifts, and/or bond supply shifts • shifts cause bond prices AND interest rates to change
Example 1: the Fisher effect • expected inflation 3%
exp. inflation rises to 4% • bond demand -- real return declines -- Bd decreases • bond supply -- real cost of borrowing declines -- Bs increases
bond price falls • interest rate rises
Fisher effect • expected inflation rises, nominal interest rates rise
bond demand • decline in income, wealth • Bd decreases • P falls, i rises • bond supply • decline in exp. profits • Bs decreases • P rises, i falls
shift Bs > shift in Bd • interest rate falls
Why shift Bs > shift Bd? • changes in wealth are small • response to change in exp. profits is large • large cyclical swings in investment
Why are bonds risky? • 3 sources of risk • Default • Inflation • Interest rate
Default risk • Risk that the issuer fails to make promised payments on time • Zero for government debt • Other issuers: corporate, municipal, foreign have some default risk • Greater default risk means a greater yield
Inflation risk • Most bonds promise fixed interest payments • Inflation erodes the real value of these payments • Future inflation is unknown • Larger for longer term bonds
Interest rate risk • Changing interest rates change the value (price) of a bond in the opposite direction. • All bonds have interest rate risk • But it is larger for the long term bonds
