Title: Chapter 6 Government Bonds
1Chapter 6Government Bonds
- How are Treasury bonds and notes sold in the
primary market? In the secondary market? - How do we adjust bond prices to reflect accrued
interest? - What are agency bonds?
- What types of individuals would be interested in
municipal bonds?
2Some US Treasury facts
- US Dept of Treasury is the largest debt issuer in
the world - Treasury securities about 3 trillion while all
corporate issues are about 1½ trillion - Debt from years of running a federal budget
deficit - Recall difference between T-bills, T-notes, and
T-bonds - Weve already discussed T-bills
3Primary MarketT-bonds and T-notes
- T-bonds and T-notes use auction procedure
- Coupon rate is set based on the results of the
stop bid yield of the auction - Rounded down to the nearest eighth
- Typical auction schedule
- 2-year notes once a month
- 5- and 10-year quarterly
- 30-year semi-annually
- The Federal Reserve acts as agent for US Treasury
4Competitive vs. Non-Competitive Bids
- Why are you not shut out if you bid
non-competitively (quantity bid)? - Which is better?
- By making a competitive bid you are setting the
maximum price (minimum yield) that you will accept
5Primary dealers
- Approximately 25 dealers are designated as
primary dealers - Only ones that deal directly with the Fed
- They submit bids for yields based on
noncompetitive (quantity) or competitive basis - They must participate
6When issued market
- After the Treasury officially announces the
auction, but before the securities are actually
issued, trading begins on the securities in the
when issued market - When issued market trading ends when the
securities are issued - Helps primary dealers determine the best price to
offer in the upcoming auction
7Short squeeze
- When trades in the when issued market exceed the
actual amount available in the auction, prices
can be volatile - Salomon tried to corner the market by owning a
majority of a particular issue - They tried to exploit short sellers who would
have to close out their position - Few bonds were available so price rose
- There are limits that are supposed to prevent
this so Salomon got in trouble
8Sources of dealer profits
- Bid-ask spread
- Sell at high price and buy at the low price
- Price appreciation of securities held
- Carry
- Dealers typically finance their securities
inventories using repurchase agreements (the
T-notes, T-bonds are highly liquid collateral) - In a normal yield curve environment, what is the
net yield of such a position?
9T-note and T-bond price quotes
- Although bids are based on yields, reported price
quotes are based on dollars assuming a 100 face
value - Basically prices are in percentage terms
- Quotes are in 32nds (or 64ths)
- 10020 means 100 and 20/32
- Prices are listed by maturity month and year
- All T-notes and T-bonds mature on the 15th
- n signifies that the issue is a note (see p.212)
10Accrued interest
- Recall that one of the principles of accounting
is accrual basis - Recognize income when earned not when cash is
received - If a bond is sold between coupons, shouldnt the
seller get part of the coupon?
11An Example
- Suppose that a 5, 1,000 bond matures on
December 15 and today is March 19 - Kurt sells the bond to Belinda
Last Dec 15

June 15

12Dividing the coupon
Last Dec 15

March 19
Coupon 25
Coupon 25
Kurt
Belinda
Belinda owns for (31-19)303115 88 days
Kurt owns for 313128(19-15) 94 days
13Dividing the coupon p.2
- Rather than waiting for June 15 coupon, Belinda
will pay Kurt on the sale date for fraction of
coupon - Total price paid to Kurt on the sale date is the
invoice price which equals the base (quoted)
price plus the accrued interest - Invoice price is the PV of cash flows
- This is different from quote in WSJ
14Example continued
- Suppose the yield on the above bond is 6
- We can discount the cash flows to get a bond
price of 1005.67 - Since Kurt owned the bond for 94 out of 182 days,
the accrued interest portion of the price is
15The Same Example with less work
- Use the calculator
- The base price becomes a plug between the present
value of the cash flows and the accrued interest - See book for another example
16The call feature
- Details will come in corporate bond chapter
- If a bond is callable, it can be redeemed by the
issuer prior to maturity - Why call a bond?
- Some Treasuries used to be issued as callable
- But callable Treasuries still exist in the market
17A little review
- Recall that a bond can be viewed as a portfolio
of zero coupon bonds - Example of a 1½ year bond

18Stripping Treasuries
- Converting coupon T-notes or T-bonds to zero
coupon bonds is called stripping - Why do this?
- Investors may be interested in tailoring their
portfolios to have specific cash flows - Use the STRIPS program approved by the US
Treasury Separate Trading of Registered
Interest and Principal Securities
19Strip example in book p. 216
- 5 year, 1 million, 5 coupon T-note
- Why is the value of the stripped securities
different from the original bond price? - In column 3, the value of the coupons is from
discounting by the YTM of the bond - In column 6, coupons are discounted by spot rate
- Note that the values of zero coupon bonds (using
spot rates) should equal the bond price or else
arbitrage will take place
20Federal Agency Debt
- Federal government sets up fiscal agents to
promote credit availability - Agencies borrow from capital markets and use
money to make loans - Loans offered in sectors of the economy to
promote credit availability such as housing,
education, farming - Although not explicitly backed by the full faith
and credit of the US Government, agency
securities are regarded as safe
21Some federal agencies
- Federal National Mortgage Association (FNMA) or
Fannie Mae - Federal Home Loan Mortgage Corporation (FHLMC) or
Freddie Mac - Student Loan Marketing Association (SLMA) or
Sallie Mae
22A note about agency debt
- Investors in agency bonds are not secured by any
assets underlying the agencys loans - The issues are debentures
- Debentures are unsecured debt and is backed only
by the general credit of issuer
23Municipal bonds
- Aside from the federal government, state and
local governments also issue bonds - Can be counties, school districts, townships
- Bonds issued by governments other than the
federal government are called municipal bonds or
munis
24Issuers
- States
- State GO bonds have little default risk since
default would impair future issues - Local governments such as cities and counties
- Issuer may buy default protection
- Special districts such as school districts,
sanitary district
25Types of munis
- General obligation (GO) bonds are backed by
full faith and credit of issuer - Ability to raise taxes determines default risk
- Revenue bonds fund specific projects and
bond cash flows are derived from
revenues of the project - Highways may have tolls
- Industrial development bonds help fund new
construction of industrial sites for businesses
at favorable rates
26Tax treatment
- Munis are interesting because of tax status
- Government (or federal) securities are exempt
from state tax and municipal securities are
exempt from federal taxation - Usually state of issue will exempt their own
securities from tax - Exemption applies to interest, not price
appreciation
27Effect on yields
- Tax exemption of munis allows them to yield less
on a pre-tax basis
- The equivalent municipal yield is given by
28A new risk
- Weve talked about default risk and call risk
- The tax exemption of munis introduces the risk
that the tax status of the bond will change - Marginal tax rate
- Exempt status
29Muni markets
- Munis are underwritten for sale in the primary
market - See article distorting the primary market
- The secondary market is OTC
- Generally larger denominations than (federal)
government debt
30Summary of Chapter 6
- Federal government sells T-bonds and notes
- Accrual accounting pays bond sellers a portion of
the coupon income - Municipal bonds are issued by governments other
than the federal government and have special tax
treatment
