Factors Affecting Yields Among
Securities
 Debt securities offer different yields because
they exhibit different characteristics
Unfavorable characteristics result in higher
yields to entice investors
2
Factors Affecting Yields Among
Securities
 Security yields and prices are affected by levels
and changes in:
Default risk (also called Credit Risk)
Liquidity
Tax status
Term to maturity
Special contract provisions such as
embedded options
3
Factors Affecting Yields Among
Securities
 Credit (Default) Risk
Benchmark: Risk-free treasury securities
Default Risk Premium = Risky security yield Treasury security yield of same maturity
Risk premiums for a particular bond can
change over time
4
Factors Affecting Yields Among
Securities
 Credit (Default) Risk
Investors can assess default risk by
checking bond ratings set by Rating
Agencies
• Moody’s Investor Service
• Standard and Poor’s Corporation
Anticipated or actual ratings changes can
impact security prices and yields
Different bonds issued by the same firm can
differ in rating
5
Factors Affecting Yields Among
Securities
 Liquidity
A liquid investment is easily converted to
cash without a loss in value
Investors pay more (lower yield) for a more
liquid investment
• Securities with lower liquidity must offer a
higher yield
Short-term, low default risk, marketable
securities have higher liquidity
6
Factors Affecting Yields Among
Securities
 Tax Status
Investors are more concerned with after-tax
return or yield
Investors require higher yields for higher
taxed securities
Investors in high tax brackets benefit most
from tax-exempt securities
7
Factors Affecting Yields Among
Securities
 Term to Maturity
Interest rates typically vary by maturity
The term structure of interest rates defines
the relationship between maturity and yield
• The Yield Curve is the plot of current
interest yields versus time to maturity
8
%
Yield
Time to Maturity
Years
An upward sloping yield curve indicates that Treasury
Securities with longer maturities offer higher annual yields
9
Factors Affecting Yields Among
Securities
 Special Provisions
Call Feature: enables borrower to buy back
the bonds before maturity at a specified price
• Call features are exercised when interest
rates have declined
• Investors demand higher yield on callable
bonds, especially when rates are expected
to fall
10
Factors Affecting Yields Among
Securities
 Special Provisions
Convertible Bonds
• Convertibility feature allows investors to
convert the bond into a specified number of
common stock shares
• Investors will accept a lower yield for
convertible bonds
11
A Closer Look At the Term Structure
 Theories Explaining Shape of Yield Curve
Pure Expectations Theory
Liquidity Premium Theory
Segmented Markets Theory
12
A Closer Look At the Term Structure
 Pure Expectations Theory
Long-term rates are average of current shortterm and expected future short-term rates
Yield curve slope reflects market
expectations of future interest rates
Investors select maturity based on
expectations
13
A Closer Look At the Term Structure
 Pure Expectations Theory
Assumes investor has no maturity
preferences and transaction costs are low
Long-term rates are averages of current short
rates and expected short rates
• Forward rate: market’s forecast of the
future interest rate
14
A Closer Look At the Term Structure
 Pure Expectations Theory
Upward Sloping Yield Curve
• Expected higher interest rate levels
• Expansive monetary policy
• Expanding economy
Downward Sloping Yield Curve
• Expected lower interest rate levels
• Tight monetary policy
15
A Closer Look At the Term Structure
 Liquidity Premium Theory
Investors prefer short-term, more liquid,
securities
Long-term securities and associated risks are
desirable only with increased yields
Explains upward sloping yield curve
When combined with the expectations theory,
yield curves could still be used to interpret
interest rate expectations
16
A Closer Look At the Term Structure
 Segmented Markets Theory
Theory explaining segmented, broken yield
curves
Assumes investors have maturity preference
boundaries, e.g., short-term vs. long-term
maturities
Explains why rates and prices vary
significantly between certain maturities
17
A Closer Look At the Term Structure
 Which Theory is Correct?
Although research results differ, there is
evidence that expectations theory, liquidity
preference theory, and segmented markets
theory all have some validity
• If term structure is used to assess
market’s expectations of future rates,
should net out liquidity premium and
unique segment characteristics
18
A Closer Look At the Term Structure
 Uses of the Term Structure
Forecast interest rates
Forecast recessions
Investment decisions
• Individuals
• Financial institutions
Financing decisions
19
International Structure of Interest
Rates
 Capital flows to the highest expected after-tax,
real (inflation and other risk-adjusted), foreign
exchange adjusted rates of return
20
International Structure of Interest
Rates
 Yield differences between countries are related
to:
Expected changes in forex rates
Varied expected real rates of return
Varied expected inflation rates
Varied country and business risk
Varied central bank monetary policy
