Term Structure of Interest Rates • The yield curve is a graph that displays therelationship between yield and maturity • Information on expected future short term rates can be implied from yield curve • Three major theories are proposed to explain the observed yield curve
Yields Upward Sloping Flat Downward Sloping Maturity Yield Curves
Today’s Yield Curve • 3-month T-Bill: 4.78% • 6-month T-Bill: 5.12% • 1-Yr T-Bill: 5.23% • 2-Yr T-Note: 5.63% • 5-Yr T-Note: 5.81% • 10-Yr T-Bond: 5.94% • 30-Yr T-Bond 6.07%
Forward Rates from Observed Long-Term Rates fn = one-year forward rate for period n yn = yield for a security with a maturity of n
Example of Forward Rates • 4 yr = 9.993 3yr = 9.660 fn = ? • (1.0993)4 = (1.0966)3 (1+fn) • (1.46373) / (1.31870) = (1+fn) • fn = .10998 or 11% • Note: this is expected rate that was used in the prior example

Theories of Term Structure • Expectations • Liquidity Preference • Upward bias over expectations • Market Segmentation • Preferred Habitat
Expectations Theory • Observed long-term rate is a function of today’s short-term rate and expected future short-term rates • Long-term and short-term securities are perfect substitutes • Forward rates that are calculated from the yield on long-term securities are market consensus expected future short-term rates
Liquidity Premium Theory • Long-term bonds are more risky • Investors will demand a premium for the risk associated with long-term bonds • Yield curve has an upward bias built into the long-term rates because of the risk premium • Forward rates contain a liquidity premium and are not equal to expected future short-term rates
Liquidity Premiums and Yield Curves Yields Observed Yield Curve Forward Rates Liquidity Premium Maturity
Market Segmentation and Preferred Habitat • Short- and long-term bonds are traded in distinct markets • Trading in the distinct segments determines the various rates • Observed rates are not directly influenced by expectations • Preferred Habitat • Modification of market segmentation • Investors will switch out of preferred maturity segments if premiums are adequate
