Ch8. Bond ETF Investing — The Innovation of Accessibility and Liquidity

The Innovation of Bond ETFs

Why it is difficult for individuals to buy individual bonds directly:

Barriers to direct bond investing:
- Minimum trade size: often $100,000 or more
- Limited access to bond information
- Wide bid-ask spreads (individual investors are at a disadvantage)
- Managing dozens of bonds with different maturities

What ETFs solve:
- Invest from as little as 1 share (as low as a few dollars)
- A diversified basket of bonds in a single instrument
- Real-time trading like a stock
- Transparent costs (expense ratio clearly stated)

Key Characteristics of Bond ETFs

Unlike Individual Bonds, ETFs Have No Maturity Date

Individual bond: principal is repaid at maturity
Bond ETF: no maturity (bonds that mature are replaced; the fund runs continuously)

→ You can invest regardless of your holding period
→ However, if rates rise, net asset value can continue to decline
→ The strategy of "buy a bond and hold to maturity" cannot be replicated with an ETF

Distributions and Capital Gains/Losses

How returns are composed in a bond ETF:

1. Distributions (interest income): interest from bonds held → paid to investors
2. Capital gain/loss: change in ETF price (moves inversely with interest rates)

Example: when rates rise
→ Distribution yield rises
→ ETF price falls (capital loss)
→ Total return = distributions − capital loss

Major US-Listed Bond ETFs

Core ETFs

AGG (iShares Core U.S. Aggregate Bond):
→ Total US bond market (Treasuries + corporates + MBS)
→ AUM: $100 billion+
→ Expense ratio: 0.03%

BND (Vanguard Total Bond Market):
→ Similar to AGG, Vanguard version
→ Expense ratio: 0.03%

TLT (iShares 20+ Year Treasury Bond):
→ US Treasuries with 20+ year maturity
→ Strong capital gains when rates fall
→ Expense ratio: 0.15%

SHY (iShares 1-3 Year Treasury Bond):
→ Short-term Treasuries; defensive when rates rise
→ Expense ratio: 0.15%

Other Notable Bond ETFs

ETF	Benchmark	Expense Ratio	Characteristics
LQD	Investment-grade US corporate bonds	0.14%	High-quality corporate bond exposure
HYG	High-yield US corporate bonds	0.48%	Higher yield, higher risk
EMB	JP Morgan USD EM bonds	0.39%	Dollar-denominated EM exposure
TIPS	iShares TIPS Bond	0.19%	Inflation-protected US government bonds

Bond ETF Taxation

US Investors

Capital gains: short-term (held &lt;1 year) taxed as ordinary income;
               long-term (held 1+ year) taxed at 0%, 15%, or 20%
Distributions: taxed as ordinary income (or qualified dividends if eligible)
Tax-advantaged accounts (IRA, 401k): defer or eliminate taxes

Strategy:
Hold in tax-advantaged accounts when possible to maximize compounding

Key Notes for International Investors

US-listed ETFs:
Capital gains: taxed according to home country rules
Distributions: 15–30% US withholding tax (check treaty rates)
→ Check your country's tax treaty with the US

Locally-listed ETFs tracking US bonds:
Taxation handled according to local rules
Often more tax-efficient for non-US investors

Bond ETF Investment Strategy

Strategy by Interest Rate Cycle

Rate-rising environment:
→ Focus on short-duration ETFs (SHY, ultra-short Treasuries)
→ Keep duration short

When rates turn lower:
→ Shift into long-duration ETFs (TLT, 20–30 year Treasuries)
→ Position for capital gains

Uncertain environment:
→ Mix intermediate-term ETFs with TIPS
→ Absorb volatility

Core-Satellite Allocation

Core: AGG or BND (60–70%)
Satellite: TLT for rate-fall positioning (10–20%)
           EMB for EM yield pickup (10–15%)
           TIPS for inflation hedge (5–10%)

Direct Bonds vs ETFs Compared

Category	Direct Bonds	Bond ETFs
Minimum investment	Tens to hundreds of thousands of dollars	As low as a few dollars (1 share)
Maturity	Defined maturity	None (open-ended)
Locked-in yield to maturity	Possible	Not possible
Liquidity	Low	High (trades like a stock)
Diversification	Difficult	Automatic
Tax handling	Complex	Relatively straightforward

Bond ETFs = no fixed maturity; returns from distributions + capital gain/loss Rates rising → short-duration ETFs (SHY, ultra-short) / rates falling → long-duration ETFs (TLT, 20–30yr) Tax treatment: capital gains and distributions taxed per your home country rules For most individual investors, ETFs are superior to direct bond investing
