Bond Types
Government Bonds
Treasury Bills (T-Bills):
Maturity: 4 weeks to 1 year
Income: Sold at discount, mature at par (no coupon)
Risk: Essentially zero credit risk
Tax: Federal tax only (exempt from state/local)
Best for: Cash management, short-term parking
Treasury Notes (T-Notes):
Maturity: 2 to 10 years
Income: Semi-annual coupon payments
Risk: Interest rate risk (prices fall when rates rise)
Tax: Federal tax only
Best for: Core fixed-income allocation
Treasury Bonds (T-Bonds):
Maturity: 20 to 30 years
Income: Semi-annual coupon
Risk: High interest rate sensitivity (long duration)
Tax: Federal tax only
Best for: Long-term income, pension matching
TIPS (Treasury Inflation-Protected Securities):
Maturity: 5, 10, or 30 years
Income: Fixed coupon on inflation-adjusted principal
Risk: Protected against inflation, still has real rate risk
Tax: Federal tax on coupon AND inflation adjustment (phantom income)
Best for: Inflation protection, real return preservation
Warning: Best held in tax-advantaged accounts due to phantom income
I-Bonds (Series I Savings Bonds):
Maturity: 30 years (redeemable after 1 year, 3-month interest penalty before 5 years)
Income: Fixed rate + inflation rate (adjusted semi-annually)
Limit: $10,000 per person per year (electronic)
Risk: Essentially none (no market price fluctuation)
Best for: Inflation-protected savings, emergency fund supplement
Municipal Bonds
General Obligation (GO) Bonds:
Backed by: Full faith and credit (taxing power) of issuer
Risk: Low (depends on municipality's fiscal health)
Tax: Usually exempt from federal tax
Often exempt from state tax if same state
Revenue Bonds:
Backed by: Specific revenue source (toll road, water utility, hospital)
Risk: Higher than GO (depends on project revenue)
Tax: Same as GO bonds
Tax-Equivalent Yield Calculation:
Tax-equivalent yield = Muni yield / (1 - marginal tax rate)
Example: 3.5% muni yield, 37% federal tax bracket
Tax-equivalent = 3.5% / (1 - 0.37) = 5.56%
With state tax (e.g., 10%):
Tax-equivalent = 3.5% / (1 - 0.37 - 0.10) = 6.60%
Decision rule: Compare tax-equivalent yield to comparable taxable bond yield.
If tax-equivalent > taxable yield -> buy muni
If tax-equivalent < taxable yield -> buy taxable
Corporate Bonds
Investment Grade (rated BBB/Baa or higher):
Risk: Low to moderate credit risk
Yield: 1-2% above Treasuries (credit spread)
Best for: Core bond allocation with yield pickup
High Yield (rated BB/Ba or below, "junk bonds"):
Risk: Meaningful credit risk, higher default probability
Yield: 3-6% above Treasuries
Best for: Yield-seeking investors with diversification
Warning: Correlates more with stocks than with other bonds
Not a safe-haven asset during market stress
Yield Curve
Interpreting the Yield Curve
The yield curve plots interest rates across different maturities:
Normal (upward sloping):
Short rates < Long rates
Interpretation: Economy is healthy, investors demand premium for longer lending
Action: Typical environment, standard ladder approach works
Flat:
Short rates = Long rates
Interpretation: Transition period, uncertainty about economic direction
Action: Shorter-duration bonds may offer similar yield with less risk
Inverted (downward sloping):
Short rates > Long rates
Interpretation: Market expects economic slowdown or rate cuts
Historically: Has preceded every US recession since 1955
Action: Consider locking in long-term rates before they fall further
Steepening:
Long rates rising faster than short rates
Often signals economic recovery or inflation expectations
Action: Be cautious with long-duration bonds
Flattening:
Short rates rising toward long rates
Often signals tightening monetary policy
Action: Reduce duration exposure
Duration and Risk
Understanding Duration
Duration: Measure of a bond's price sensitivity to interest rate changes.
Modified Duration example:
A bond with duration of 5 years will lose approximately 5%
in price if interest rates rise 1%.
10-year Treasury with 4% coupon:
Duration approximately 8 years
If rates go from 4% to 5%: price drops ~8%
If rates go from 4% to 3%: price rises ~8%
Duration rules of thumb:
- Higher coupon = lower duration (getting cash back sooner)
- Longer maturity = higher duration
- Zero-coupon bonds: duration = maturity (maximum sensitivity)
Practical implications:
If you expect rates to RISE: shorten duration (buy shorter bonds)
If you expect rates to FALL: lengthen duration (buy longer bonds)
If uncertain: match duration to your investment horizon
Duration by Bond Type
| Bond Type | Typical Duration | Rate Sensitivity |
|---|---|---|
| Money market / T-bills | 0-0.5 years | Very low |
| Short-term bonds (1-3 yr) | 1-3 years | Low |
| Intermediate bonds (3-10 yr) | 3-7 years | Moderate |
| Long-term bonds (10-30 yr) | 8-20 years | High |
| TIPS (10 yr) | 7-9 years | Moderate (real rates) |
| High yield | 3-5 years | Moderate (but credit risk dominates) |
Bond Ladder Strategy
How to Build a Ladder
A bond ladder: Buy bonds with staggered maturities.
As each bond matures, reinvest at the longest rung.
Example: $100,000 across 5 rungs
Rung 1: $20,000 in 1-year bonds
Rung 2: $20,000 in 2-year bonds
Rung 3: $20,000 in 3-year bonds
Rung 4: $20,000 in 4-year bonds
Rung 5: $20,000 in 5-year bonds
Year 1: Rung 1 matures -> reinvest in new 5-year bond
Year 2: Rung 2 matures -> reinvest in new 5-year bond
...and so on
Benefits:
- Reduces interest rate risk (averaging across rate environments)
- Provides regular liquidity (annual maturities)
- Eliminates need to time interest rate changes
- Predictable income stream
When to use:
- Income-focused investors
- Retirees needing predictable cash flow
- Anyone uncomfortable timing interest rates
Ladder Implementation Options
Individual Bonds (for larger portfolios, $100K+):
- Buy individual Treasury or muni bonds through broker
- Know exactly when each bond matures and what you'll receive
- No management fees
- Requires more effort to build and maintain
Bond ETFs (for smaller portfolios):
- Target maturity ETFs (e.g., iShares iBonds, Invesco BulletShares)
- ETF matures in a specific year, distributing proceeds
- Combine multiple target-date ETFs to build a ladder
- Low cost, easy to manage, liquid
Example ETF ladder:
IBTA (iShares iBonds Dec 2026 Term Treasury) -> 2026
IBTB (iShares iBonds Dec 2027 Term Treasury) -> 2027
IBTD (iShares iBonds Dec 2028 Term Treasury) -> 2028
...and so on
Credit Analysis
Rating Scale
Investment Grade:
AAA/Aaa: Highest quality (US Treasuries, Microsoft, J&J)
AA/Aa: High quality (Apple, Exxon)
A/A: Upper-medium (most large corporations)
BBB/Baa: Medium grade (still investment grade, but watch carefully)
Below Investment Grade ("Junk"):
BB/Ba: Speculative (fallen angels, leveraged companies)
B/B: Highly speculative
CCC/Caa: Substantial risk of default
CC/Ca: Near default
D: In default
Default Rates (historical annual average):
AAA: 0.00%
AA: 0.02%
A: 0.07%
BBB: 0.18%
BB: 0.81%
B: 4.28%
CCC: 26.85%
Portfolio Allocation
Bond Allocation by Life Stage
Young Professional (25-40):
10-30% bonds
Focus: Intermediate-term, total return
Example: AGG or BND (broad market bond ETF)
Pre-Retirement (40-55):
30-50% bonds
Focus: Mix of intermediate and short-term
Begin building income-producing allocation
Early Retirement (55-70):
40-60% bonds
Focus: Ladder for income, TIPS for inflation protection
Tax-advantaged munis in taxable accounts
Late Retirement (70+):
50-70% bonds
Focus: Short to intermediate, capital preservation
Emphasize quality (Treasury, investment-grade)
Rule of thumb: Bond allocation = your age (or age - 10 for more growth)
This is a starting point, not a rigid rule.
Where to Hold Which Bonds
Tax-advantaged accounts (IRA, 401k):
- Corporate bonds (fully taxable interest)
- TIPS (phantom income from inflation adjustment)
- High-yield bonds (taxed as ordinary income)
Taxable accounts:
- Municipal bonds (tax-exempt interest)
- Treasury bonds (state tax exempt)
- I-Bonds (tax deferred until redemption)
This tax-efficient placement maximizes after-tax return.
