## 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.
