Vanguard Total Bond Market ETF holds more than 11,400 bonds, including US Treasuries, mortgage-backed securities and investment-grade corporate bonds, tracking the Bloomberg US Aggregate Float Adjusted Index. With a 4.82 percent 30-day SEC yield in mid-September 2026, it provides income-oriented exposure to the US bond market at a low 0.03 percent expense ratio, with a price around $71.31 in one October 2026 snapshot and a dividend yield of 4.12 percent in another.
Credit quality is universally investment-grade, BBB and above, but a higher 5.7-year duration can create sensitivity to interest rate changes. In one 5-year comparison, growth of $1,000 was $979, worse than the muni fund comparator, reflecting the rate shock of recent years. For a single core bond holding, BND remains the benchmark choice.
What we like- Over 11,400 bonds
- 0.03 percent expense ratio
- 4.82 percent 30-day SEC yield mid-September 2026
- Investment-grade only
Watch out for- 5.7-year duration creates rate sensitivity
- 5-year total return was negative in one comparison
- No inflation-protected bonds

Best for: Closest core rival

Free planNot applicable
iShares Core US Aggregate Bond ETF is the BlackRock rival to BND, with $139.16 billion in assets, a price around $96.05 in one October 2026 snapshot, and a 0.03 percent expense ratio. It tracks the same broad US investment-grade bond market, holding Treasuries, agencies, corporates and mortgage-backed securities.
Its performance closely tracks BND, and the choice between them often comes down to brokerage preference or tax-lot management. For investors who already hold iShares funds, AGG is the natural core bond holding, with liquidity that suits large trades.
What we like- $139.16 billion in assets
- 0.03 percent expense ratio
- Broad aggregate exposure
- High liquidity
Watch out for- Similar duration risk to BND
- 5-year return also pressured by rates
- No international bonds

Free planNot applicable
Schwab US Aggregate Bond ETF offers the same core aggregate exposure at 0.03 percent, with $10.78 billion in assets and a price around $22.45 in one October 2026 snapshot. It suits Schwab brokerage clients who want a single core bond fund without switching platforms.
Its smaller asset base means slightly lower liquidity than BND or AGG, but it remains ample for most investors. For Schwab clients, SCHZ is the obvious core bond choice.
What we like- 0.03 percent expense ratio
- $10.78 billion in assets
- Broad aggregate exposure
- Schwab ecosystem fit
Watch out for- Smaller asset base than BND or AGG
- Similar duration risk
- No international bonds

Free planNot applicable
SPDR Portfolio Aggregate Bond ETF is State Street low-cost core bond fund, with $10.44 billion in assets, a price around $24.73 in one October 2026 snapshot, a 0.03 percent expense ratio and a dividend yield around 4.22 percent. It tracks the broad US investment-grade bond market, with Treasuries and investment-grade bonds as its core holdings.
One guide lists SPAB among the best fixed income ETFs for cost-conscious investors, citing its very low expense ratio and diverse portfolio. For State Street or SPDR users, SPAB is the natural core bond holding.
What we like- 0.03 percent expense ratio
- $10.44 billion in assets
- Broad aggregate exposure
- State Street scale
Watch out for- Smaller asset base than BND or AGG
- Similar duration risk

iShares National Muni Bond ETF targets high-quality municipal bonds from across the US, holding 7,544 securities, with $53.92 billion in assets, a price around $103.82 in one October 2026 snapshot, and a 0.05 percent expense ratio. It paid $3.42 per share over the trailing 12 months, working out to a 3.3 percent yield at a recent $102.48 share price.
That headline yield looks lower than BND 4.2 percent distribution yield, but muni income is exempt from federal tax, so it can beat taxable bonds after tax for high earners. In one 5-year comparison, MUB maximum drawdown was 11.6 percent versus 17.4 percent for BND, and growth of $1,000 was $1,015 versus $979. For taxable accounts, MUB deserves a close look.
What we like- Tax-exempt federal income
- $53.92 billion in assets
- 7,544 securities
- Lower 5-year drawdown than BND in one comparison
Watch out for- Lower headline yield at 3.3 percent

Vanguard Total International Bond ETF offers a diversified international bond portfolio, with $84.46 billion in assets, a price around $47.24 in one October 2026 snapshot, and a 0.07 percent expense ratio. One 2026 guide cites a competitive yield of 4.85 percent, while another snapshot lists a dividend yield of 4.64 percent and a price of $47.29.
Currency hedging reduces exchange-rate risk, but international rate cycles differ from US cycles, adding diversification that can smooth returns. For investors who want global bond exposure alongside US core holdings, BNDX is the leading international choice.
What we like- $84.46 billion in assets
- Diversified international bonds
- 4.85 percent yield in one 2026 guide
- Currency hedged
Watch out for- Higher 0.07 percent expense ratio
- International rate and currency risks
- Lower yield than some US funds in other snapshots

iShares 5-10 Year Investment Grade Corporate Bond ETF (IGIB)
Best for: Mid-term corporate income
Visit ishares.com
Starting priceSee website
Free planNot applicable
iShares 5-10 Year Investment Grade Corporate Bond ETF mirrors a benchmark of high-quality corporate debt, all denominated in US dollars, with maturities from five to 10 years, and no single position above 0.23 percent of assets. It paid $2.56 per share over the trailing 12 months, working out to a 4.80 percent yield at a recent $52.95 share price, versus 4.00 percent for BND in the same comparison.
That higher payout appeals to income seekers, but corporate bonds carry credit risk that Treasuries do not, and its 5-year drawdown of 20.60 percent exceeded BND 17.90 percent in one comparison. For income-focused investors who accept corporate risk, IGIB is a strong mid-term choice.
What we like- Higher yield at 4.80 percent in one comparison
- High-quality corporate debt
- 5 to 10 year maturities
- No single holding above 0.23 percent
Watch out for- Corporate credit risk
- 5-year drawdown of 20.60 percent in one comparison
- No Treasury or muni exposure

Vanguard Short-Term Corporate Bond ETF offers short-term investment-grade corporate bonds, with $44.82 billion in assets, a price around $77.63 in one October 2026 snapshot, a 0.04 percent expense ratio and a dividend yield around 4.54 percent. Its short duration limits interest-rate sensitivity, making it steadier than intermediate or long-term funds when rates rise.
Corporate credit risk remains, and yields can lag longer funds when the yield curve steepens. For investors who want corporate income with less rate risk, VCSH is a leading short-term choice.
What we like- $44.82 billion in assets
- 0.04 percent expense ratio
- Short duration limits rate risk
- 4.54 percent dividend yield
Watch out for- Corporate credit risk
- Lower yield than longer funds in some periods
- No Treasury or muni exposure
How we chose
We compared funds on expense ratio, asset size, diversification, duration, liquidity and yield, using October 2026 market snapshots. BND and AGG lead on scale, SCHZ and SPAB match them on cost, MUB leads on tax efficiency, BNDX leads on international diversification, and IGIB and VCSH lead on corporate income at different maturities. Yields and prices change daily, so we reported snapshot figures and wrote See website for current prices. This article is general information only, not financial advice, and we did not claim hands-on investment experience.
Building a bond ETF portfolio
Start with a core holding, such as BND, AGG, SCHZ or SPAB, which covers the broad US investment-grade market at 0.03 percent. Add MUB in taxable accounts where the tax exemption beats taxable yields after tax, and add BNDX for international diversification where you want global exposure. Use IGIB or VCSH for a corporate income tilt, choosing maturity by your rate outlook: short-term funds suit rising-rate worries, while intermediate funds suit stable or falling rates.
Check duration before buying, since longer duration means larger price swings when rates move, and check credit quality, since corporate and high-yield funds carry default risk that Treasury funds do not. Rebalance periodically, since bond weights drift as stocks move, and hold bonds in tax-advantaged accounts where possible, except munis, which belong in taxable accounts to capture their tax benefit.
Frequently asked questions
What is the best index fixed income ETF?
Vanguard Total Bond Market ETF (BND) is best for a single core holding, with iShares AGG as the closest rival. Schwab SCHZ and SPDR SPAB match them on cost, while MUB suits taxable accounts and BNDX adds international diversification.
What is the cheapest bond ETF?
BND, AGG, SCHZ and SPAB all charge 0.03 percent, the lowest in this list. BNY Mellon Core Bond ETF (BKAG) lists 0.00 percent in one screener, but its $1.46 billion asset base is far smaller, so liquidity and tracking matter too.
Should I buy BND or MUB?
Buy BND for broad taxable bond exposure in tax-advantaged accounts, and MUB for tax-exempt income in taxable accounts, especially if you are in a high tax bracket. Compare after-tax yields, not headline yields, since muni income is federal tax-exempt.
What is duration risk?
Duration measures how much a bond fund price moves when interest rates change. A 5.7-year duration, like BND, means a 1 percent rate rise roughly cuts price by 5.7 percent, before income offsets it. Short-term funds have lower duration and steadier prices.
Are bond ETFs safe?
Bond ETFs reduce single-bond risk through diversification, but they are not risk-free. Prices fall when rates rise, corporate bonds can default, and inflation can erode real returns. Investment-grade funds are steadier than high-yield funds, but no bond fund guarantees principal.
How often do bond ETFs pay income?
Most bond ETFs pay monthly distributions, with yields that change as holdings and rates change. Check the fund 30-day SEC yield for a standardised income measure, and the distribution yield for recent payouts, since the two can differ.
