Bond ETFs don’t get nearly the attention that stock funds do, but they play a specific, deliberate role in a portfolio: reducing volatility, generating income, and — depending on which one you choose — either dampening or amplifying your sensitivity to interest rate changes. Unlike the stock ETFs covered elsewhere on this site, the single most important variable distinguishing one bond ETF from another isn’t sector or growth style — it’s duration, a measure of how sensitive a fund’s price is to interest rate movements.
This guide walks through duration first, since it’s the concept everything else in this article builds on, then compares six of the most widely held bond ETFs across the risk spectrum, from cash-like stability to long-duration Treasury exposure.
New to ETFs generally? Our What Is an ETF? guide covers the basics first.
Duration: The Concept That Explains Almost Everything Here
Duration measures roughly how much a bond fund’s price moves for every 1% change in interest rates. A fund with a duration of 2 years will move roughly 2% for a 1-percentage-point rate change; a fund with a duration of 15 years will move roughly 15% for that same 1-percentage-point change. Critically, this relationship runs in the opposite direction from what new bond investors sometimes expect: when interest rates rise, existing bond prices generally fall (since newly issued bonds now pay a more competitive rate), and when rates fall, existing bond prices generally rise.
The practical takeaway: a short-duration bond fund is built for stability — its price barely moves regardless of what the Federal Reserve does with rates. A long-duration bond fund is built to react sharply to rate changes — which can work strongly in your favor during a rate-cutting cycle, and just as strongly against you during a rate-hiking cycle. Every fund in this article sits somewhere on that duration spectrum, and that positioning is the main thing separating one from another.
Quick Comparison Table
| ETF | Category | Approx. Duration | Expense Ratio | Approx. Yield |
|---|---|---|---|---|
| BND | Total U.S. bond market | ~6 years | 0.03% | ~4.3%–4.5% |
| SHY | Short-term Treasury (1–3 yr) | ~1.9 years | ~0.15% | ~3.6%–3.7% |
| TLT | Long-term Treasury (20+ yr) | ~15–17 years | 0.15% | Varies with rates |
| SGOV | Ultra-short Treasury (0–3 month) | Under 3 months | 0.09% | ~3.5%–3.8% |
| TIP | Inflation-protected (broad) | ~7–8 years | 0.19% | Varies; inflation-linked |
| VTEB | Municipal, tax-exempt | Intermediate | 0.03% | ~3.3% (tax-exempt) |
Figures are approximate, change with market conditions, and can shift meaningfully as interest rates move. Always confirm current yield, duration, and expense ratio on the issuer’s official fund page before investing.
1. Vanguard Total Bond Market ETF (BND) — Best Core Holding
Tracks: Bloomberg U.S. Aggregate Float Adjusted Index
BND is the most widely held bond ETF in the U.S., and it earns that position by doing exactly what a “core” bond fund should: broad diversification across Treasuries, corporate bonds, and mortgage-backed securities, spanning more than 10,000 individual holdings, at a rock-bottom 0.03% expense ratio.
Worth knowing: iShares’ AGG tracks a nearly identical index at the same 0.03% expense ratio, and the two funds perform almost interchangeably for most retail investors. The choice between BND and AGG generally comes down to which brokerage prices it better or which one you already hold — there’s little practical reason to strongly prefer one over the other.
Best for: Investors who want one diversified core bond holding without needing to choose between Treasuries, corporates, and mortgage-backed securities individually.
2. iShares 1-3 Year Treasury Bond ETF (SHY) — Best for Stability
Tracks: Short-term (1–3 year) U.S. Treasury bonds
SHY sits at the short end of the duration spectrum, meaning its price is only mildly affected by interest rate changes. It won’t generate the sharp price gains a longer-duration fund can produce during a rate-cutting cycle, but it also won’t experience the sharp declines a fund like TLT can see when rates rise.
Worth knowing: SHY is backed exclusively by U.S. Treasuries, meaning it carries essentially no credit risk (the risk that a bond issuer defaults) — its main risk is the modest price sensitivity that comes from its still-existing, if limited, duration.
Best for: Investors prioritizing capital stability and predictability over maximizing yield or making a rate-direction bet.
3. iShares 20+ Year Treasury Bond ETF (TLT) — Highest Rate Sensitivity
Tracks: Long-term (20+ year) U.S. Treasury bonds
TLT sits at the opposite end of the spectrum from SHY. With a duration in the 15-17 year range, its price can move roughly that many percentage points for each 1-percentage-point shift in interest rates — a far larger swing than a typical stock investor might expect from a “safe” government bond fund.
Worth knowing: TLT is sometimes used specifically as a portfolio hedge against stock market declines, since Treasury prices have historically tended to rise during periods of stock market stress and flight-to-safety buying. It’s also a concentrated bet on the direction of long-term interest rates — TLT experienced significant price declines during the rate-hiking period of 2022-2023, illustrating that “Treasury bond fund” doesn’t automatically mean “low volatility.”
Best for: Investors who specifically want maximum interest-rate sensitivity, either as a directional bet on falling rates or as a hedge against equity market downturns — not a typical “safe” core holding for most portfolios.
4. iShares 0-3 Month Treasury Bond ETF (SGOV) — Most Cash-Like
Tracks: Ultra-short-term (0–3 month) U.S. Treasury bills
SGOV holds Treasury bills with maturities under three months, giving it a duration so short that its price barely moves regardless of what happens with interest rates. It’s often used as a place to hold cash-equivalent money inside a brokerage account while still earning a yield close to prevailing short-term rates.
Worth knowing: SGOV’s historical maximum drawdown has been negligible compared to every other fund in this article — a reflection of just how minimal its interest rate sensitivity is. The trade-off is that its yield moves closely with short-term rates, meaning it can offer a lower yield than intermediate or long-duration bonds during periods when the yield curve is shaped differently than usual.
Best for: Investors looking for a place to park cash or an emergency-fund-style allocation inside a brokerage account, prioritizing stability and liquidity over yield maximization.
5. iShares TIPS Bond ETF (TIP) — Inflation Protection
Tracks: Broad Treasury Inflation-Protected Securities (TIPS)
TIP holds Treasury Inflation-Protected Securities — government bonds whose principal value adjusts with inflation, as measured by the Consumer Price Index. That structure is designed to help protect purchasing power during inflationary periods, a role a standard nominal bond fund like BND doesn’t specifically play.
Worth knowing: For investors who want inflation protection with less interest rate sensitivity, Vanguard’s VTIP holds shorter-duration TIPS (around 2.5 years, versus TIP’s 7-8 years), at a lower 0.03%-0.04% expense ratio — a meaningful trade-off between TIP’s broader duration exposure and VTIP’s added stability.
Best for: Investors specifically concerned about inflation eroding their bond portfolio’s purchasing power, as a complement to — not a replacement for — a core nominal bond holding like BND.
6. Vanguard Tax-Exempt Bond ETF (VTEB) — Best for Taxable Accounts
Tracks: Investment-grade municipal bonds issued by U.S. state and local governments
VTEB’s defining feature isn’t its duration profile — it’s tax treatment. Interest from municipal bonds is generally exempt from federal income tax (and sometimes state tax, depending on your state of residence and the specific bonds held), making VTEB structurally different from every other fund in this article, all of which generate income taxed at your ordinary income rate in a taxable account.
Worth knowing: That tax exemption is why municipal bond funds like VTEB typically show a lower headline yield than a taxable bond fund like BND — the relevant comparison for a taxable-account investor is the after-tax yield, not the sticker yield, since VTEB’s income isn’t taxed the same way BND’s is. For investors in higher tax brackets, that after-tax comparison can favor VTEB even with its lower nominal yield.
Best for: Investors holding bonds specifically in a taxable brokerage account (rather than an IRA or 401(k)) who want to reduce the tax drag on their bond income.
Bond ETFs and Account Type: Where You Hold Them Matters
This is a detail that connects directly to our Best ETFs for a Roth IRA guide. Interest income from most bond ETFs — BND, SHY, TLT, SGOV, and TIP among them — is generally taxed as ordinary income, which can mean a meaningfully higher tax rate than the qualified dividend rate that applies to many stock ETFs. That’s part of why many investors specifically prioritize holding taxable bond funds inside tax-advantaged accounts like a Roth or traditional IRA, reserving taxable brokerage accounts for tax-exempt options like VTEB or for tax-efficient stock funds instead. This is general tax information, not personalized advice — a tax professional can help you determine what’s appropriate for your specific accounts and tax bracket.
Which Bond ETF Fits Your Situation?
Want one diversified core bond holding: BND (or AGG — functionally interchangeable).
Want maximum stability and minimal interest rate risk: SHY for short-term Treasuries, or SGOV for something even closer to cash.
Want to make a directional bet on falling rates, or hedge against a stock market downturn: TLT — understanding its high volatility relative to other “safe” bond funds.
Want protection against inflation eroding your bond portfolio’s value: TIP for broader TIPS exposure, or VTIP for a shorter-duration, lower-volatility version of the same idea.
Are investing through a taxable brokerage account and want to reduce your tax bill on bond income: VTEB, weighed against its lower headline yield using an after-tax comparison.
Frequently Asked Questions
Can bond ETFs lose money? Yes. Bond ETF prices can decline, particularly when interest rates rise, and longer-duration funds like TLT can see substantial price swings in either direction. Bonds are generally less volatile than stocks, but “less volatile” doesn’t mean risk-free.
What’s the difference between BND and AGG? Very little in practice — both track a similar broad, investment-grade U.S. bond index at the same 0.03% expense ratio, and their performance has historically been nearly identical. The choice mostly comes down to brokerage preference.
Why would I choose a short-duration bond fund over one with a higher yield? Yield and price stability are a trade-off. Short-duration funds like SHY or SGOV typically offer more price stability but can offer a lower yield than intermediate or long-duration alternatives, depending on the shape of the yield curve at any given time. The right choice depends on whether you prioritize stability or income, and your specific time horizon for the money.
Is TLT a good hedge against a stock market crash? TLT has historically tended to rise during some periods of stock market stress, as investors moved toward the safety of long-term Treasuries — but this relationship isn’t guaranteed to hold in every market environment, and TLT carries its own substantial volatility tied to interest rate movements. It shouldn’t be treated as a risk-free hedge.
Should I hold bond ETFs in a taxable account or a retirement account? Many investors prioritize holding higher-taxed bond funds (like BND, SHY, or TLT) inside tax-advantaged accounts, while using tax-exempt options like VTEB in taxable accounts, since municipal bond income avoids federal tax regardless of account type. This is general information, not a personalized recommendation — a tax professional can advise on your specific situation.
What does “duration” actually tell me? Duration estimates how much a bond fund’s price will move for each 1-percentage-point change in interest rates. A fund with a 6-year duration (like BND) will move roughly 6% for a 1% rate change; a fund with a 15-year duration (like TLT) will move roughly 15% for that same change. Higher duration means more price sensitivity to rate changes, in both directions.
