    • Fixed-income securities

      • Treasury Securities
      • Federal Agency Securities
      • Corporate Securities
      • Municipal Securities
      • Mortgage-backed Securities
      • Derivatives (CDO's, CDS's, etc.)

    • Fixed-Income Market Participants

      • Issuers: Governments, Corporations, States, Municipalities, SPVs
      • Intermediaries: Primary Dealers, Other Dealers, Investment Banks, Credit-rating Agencies, Credit Enhancers, Liquidity Enhancers
      • Investors: Governments, Pension Funds, Insurance Companies, Commercial Banks, Mutual Funds, Hedge Funds, Foreign Institutions, Individuals
    • Bonds
      Debt obligations of issuers (borrowers) to bondholders (creditors)
    • When the bond matures, the issuer repays the debt by paying the bond's par value
    • The coupon rate of the bond determines the interest payment: The annual payment is the coupon rate times the bond's par value
    • Treasury notes are issued with original maturities ranging between 1 and 10 years, while Treasury bonds are issued with maturities ranging from 10 to 30 years
    • Bond example

      • Par value of $1,000, coupon rate of 8%, 30-year maturity
    • Bond types based on coupon or cash flow pattern
      • Straight-bond
      • Zero-coupon bond
      • Deferred-coupon bond
      • Perpetuity bond
    • Foreign bonds
      Bonds issued by a borrower from a country other than the one in which the bond is sold
    • Eurobonds
      Bonds denominated in one currency, but sold in other national markets
    • Inverse Floaters

      Bonds where the coupon rate falls when the general level of interest rates rises
    • Asset-Backed Bonds

      Bonds where the payments are tied to the performance of a particular asset
    • Catastrophe Bonds
      Bonds that transfer "catastrophe risk" from the firm to the capital markets
    • Indexed Bonds

      Bonds where payments are tied to a general price index or the price of a particular commodity
    • Example 1: 3-year coupon bond
      • Principal of $1,000, annual coupon payment of 5%
    • Valuation components
      • Time value of principal and coupons
      • Risks: Inflation, Credit, Timing (callability), Liquidity, Currency
    • Valuation of discount bonds

      1. P0 = F / (1 + r)^T
      2. P0 = Present value
      3. F = Face value
      4. r = Interest rate
      5. T = Maturity
    • Valuation of coupon bonds

      1. Discount the cashflow by the opportunity cost of capital
      2. P0 = C1 / (1 + y)^1 + C2 / (1 + y)^2 + ... + (C + F) / (1 + y)^T
      3. P0 = Present value
      4. C = Coupon payment
      5. y = Yield to maturity
      6. T = Maturity
      7. F = Face value
    • Example 2: IBM bond
      • Pays $115 every September 30 for 5 years, plus $1,000 in September 2025
      • Yield to maturity is 7.5%
    • Example 2 continued

      • Another bond: $100 interest payment per year, 5 year maturity, $1,000 face value, 12% yield to maturity
    • Coupon bond
      Bond that pays a coupon (interest payment) annually
    • Valuation of Coupon Bonds

      1. Discount the cashflow by the opportunity cost of capital (normally government bill rate)
      2. Calculate the present value of the bond
    • P0
      Present value of the bond
    • y
      Yield to maturity
    • F
      Face value of bond
    • For pure discount bonds, the YTM's are the current spot rates
    • (P0, y, C) is over-determined; any two determines the third
    • Valuation of Coupon Bonds
      • Example 2
      • Example 3
    • As interest rates rise and fall
      Bondholders experience capital losses and gains
    • Bond prices and yields

      • Negative relationship: larger yields mean lower bond prices
      • Non-linear relationship: progressive increases in the interest rate result in progressively smaller reductions in the bond price
    • Yield to maturity (YTM)

      The interest rate that makes the present value of the bond's payments equal to its price
    • Interest rate risk
      • As interest rates rise, bondholders experience capital losses
      • As interest rates fall, bondholders experience capital gains
      • These gains or losses make fixed-income investments risky, even if the coupon and principal payments are guaranteed
    • Duration
      The weighted average term to maturity (or the times to each of the cash payments)
    • Modified duration

      Sensitivity of bond prices to yield changes = Duration/(1+yield)
    • Measures of Interest rate risk
      • Example 5
    • Duration decreases with coupon rate
    • Duration decreases with YTM
    • Duration usually increases with maturity
