Key points (as at Q2 2026)
- A bond ETF holds a basket of bonds and pays the interest as regular distributions; unlike shares, bond prices move inversely to interest rates.
- Duration is the single most important concept: it measures how much a fund's price moves when rates change.
- The ASX menu spans government (AGVT, VGB), composite (IAF, VAF), floating-rate (FLOT, QPON), cash (AAA) and credit/hybrid (HBRD, SUBD) funds.
- Bond distributions carry no franking credits. General information only, not financial advice.

Bond ETFs are one of the least understood corners of the ASX. They are often described as the "defensive" part of a portfolio, but the way they actually behave — including why they can fall in value — surprises many investors. This guide explains the mechanics in plain English, then maps them onto the real funds available on the ASX, with live fee and yield data for each category.

What a bond ETF is and how distributions work
A bond is a loan. When a government or company issues a bond, it borrows money and agrees to pay regular interest (called a coupon) and return the principal at a set maturity date. A bond ETF holds a basket of these bonds and passes the coupon payments to you as regular distributions — typically monthly or quarterly, more frequently than most share ETFs.
Two features make bond ETFs behave differently from share ETFs:
- Income comes from interest, not dividends. A bond ETF's distributions are coupon payments. They are generally more predictable than share dividends, but they are taxed as ordinary income and carry no franking credits — franking is an equity concept and bonds are not equity.
- Prices move inversely to interest rates. When interest rates rise, newly issued bonds pay more, which makes existing lower-rate bonds less valuable — so their price falls. When rates fall, the reverse happens. This single relationship explains most of what a bond ETF does.
Duration: the most important concept
Duration measures how sensitive a bond fund's price is to interest-rate changes, expressed in years. As a rule of thumb, a fund with a duration of 5 years would be expected to fall by approximately 5% if interest rates rose by 1%, and rise by approximately 5% if rates fell by 1%, all else being equal.
- Short duration (e.g. cash and floating-rate funds) means low sensitivity to rates — more price stability, but typically a lower yield.
- Long duration (e.g. long-dated government bond funds) means high sensitivity — larger price swings, with more to gain if rates fall and more to lose if they rise.
The 2022 bond sell-off is the clearest illustration. Central banks raised interest rates rapidly to combat inflation, and the price of existing bonds fell as a result. Longer-duration bond ETFs fell significantly — a year in which "defensive" assets lost value surprised many investors. Past performance is not a reliable indicator of future returns, and ETFLens does not forecast interest rates. The point is structural: a bond ETF's price can fall, and duration tells you roughly how much it might move when rates change.
This is also why a bond ETF's running yield is not the same as its total return. The yield tells you the income being distributed; the total return also includes any change in the price of the underlying bonds. A fund can have a healthy yield and still post a negative total return in a year when rates rise.
Three "yields" that are not the same thing
Bond fund yields are quoted in several ways, and confusing them is a common source of disappointment. The three you will see most often:
- Distribution (running) yield — the income paid out over the past 12 months as a percentage of the current price. This is the figure ETFLens shows. It tells you the recent income, not the future total return.
- Yield to maturity (YTM) — an estimate of the total return if the underlying bonds were held to maturity, accounting for the price paid versus face value. It is generally a better guide to forward income than the running yield, though it is still not guaranteed.
- Total return — the actual change in value including both income and any movement in the price of the underlying bonds. In a year when rates rise, total return can be negative even while the distribution yield is positive.
The practical takeaway: a high distribution yield does not mean a high total return, and it can mask price falls. Always read a yield figure alongside the fund's duration and credit quality. Yields shown on this page are approximate trailing distribution yields.
The categories on the ASX
Australian bond ETFs fall into a few broad groups, ordered roughly from most rate-sensitive to least:
Government bonds — AGVT, VGB
These hold sovereign (government) bonds — the highest credit quality, since they are backed by governments. They tend to have longer duration, so they are the most sensitive to interest-rate changes. AGVT charges 0.1% p.a. (yield approximately 3.9%); VGB charges 0.16% p.a. (yield approximately 3.4%).
Composite bonds — IAF, VAF
The most widely held category. Composite funds hold a mix of government and investment-grade corporate bonds, giving diversified exposure across the Australian bond market in one fund. IAF charges 0.1% p.a. (yield approximately 3.4%); VAF charges 0.1% p.a. (yield approximately 3.2%). The two are close substitutes — see the IAF vs VAF comparison.
Floating-rate bonds — FLOT, QPON
Floating-rate funds hold bonds whose coupon resets with the cash rate, so their duration is very low and their price barely moves when rates change. That makes them far less rate-sensitive than fixed-rate funds, with income that rises and falls alongside the cash rate. FLOT charges 0.22% p.a. (yield approximately 5%); QPON charges 0.22% p.a. (yield approximately 4.4%).
Cash and ultra-short — AAA
Cash-like funds hold deposits and very short-term instruments. Duration is minimal, so the price is highly stable; the trade-off is that the yield moves directly with the cash rate. AAA charges 0.18% p.a. with a yield of approximately 3.9%.
Credit and hybrids — HBRD, SUBD
These reach for higher income by taking on more credit risk — lending to lower-rated or subordinated borrowers. They typically yield more but can behave more like shares in a market sell-off. HBRD charges 0.55% p.a. (yield approximately 5%); SUBD charges 0.39% p.a. (yield approximately 4.5%). Higher yield reflects higher risk, not a free lunch.

Credit quality: what the borrower's rating means
Alongside duration, the second big driver of a bond fund's risk is credit quality — how likely the borrowers are to repay. Bonds are rated by agencies on a scale from the highest investment grade (such as AAA) down through investment grade (to around BBB−) and then into sub-investment grade ("high yield") below that.
- Government bond funds (AGVT, VGB) sit at the top of the credit-quality scale, since they lend to governments. Their main risk is duration, not default.
- Composite funds (IAF, VAF) blend government bonds with investment-grade corporate bonds, taking on a little credit risk in exchange for a slightly higher yield.
- Credit and hybrid funds (HBRD, SUBD) deliberately take more credit risk to lift income. Subordinated debt ranks below senior bonds if a borrower fails, and hybrids can behave more like shares in a stress event — which is why their yields are higher.
Higher yield almost always means higher risk somewhere — more duration, more credit risk, or both. There is no free lunch in fixed income, and a yield figure on its own says little without knowing where the risk sits.
Bond ETFs, term deposits and individual bonds
Investors often weigh bond ETFs against two alternatives:
- Term deposits pay a fixed rate for a fixed term and (within limits) carry a government guarantee, so their capital value does not move. A bond ETF, by contrast, has a price that fluctuates with rates but offers daily liquidity and diversification across many bonds. A cash ETF such as AAA sits somewhere between the two — highly stable, but without the fixed term or guarantee of a deposit.
- Buying individual bonds directly is possible but can require larger amounts and more effort to diversify. A bond ETF packages hundreds of bonds into a single ASX trade, which is the main reason many investors use them.
Each option has different liquidity, risk and tax characteristics. Which (if any) suits an investor depends on their circumstances, which ETFLens cannot assess.
Where bonds may fit in a portfolio
This is a general framework, not a recommendation, and ETFLens does not suggest any allocation percentage. Investors generally consider bond ETFs for one or more of three roles:
- Defensive ballast — lower volatility than equities, which some investors value as a counterweight to share holdings.
- Income — regular, relatively predictable distributions from coupon payments.
- Capital stability — shorter-duration and cash-like funds aim for a more stable price than longer-dated bonds or shares.
As neutral descriptions: a composite or government bond fund may suit investors approaching or in retirement who want lower volatility than equities; a floating-rate or cash fund may suit investors seeking income with minimal interest-rate sensitivity. Whether bonds suit you at all, and in what mix, depends on your objectives, situation and needs — which ETFLens cannot assess.
How bond ETF income is taxed
Bond ETF distributions are interest income, and they are taxed differently from share dividends. The main points to understand, at a general level:
- No franking credits. Franking attaches to Australian-company dividends. Bond coupons are not dividends, so bond ETF distributions carry no franking and cannot reduce your tax the way franked share income can.
- Generally taxed as ordinary income. Interest distributions are usually included in your assessable income at your marginal tax rate, much like bank interest. Some funds may attribute small amounts of other components, set out in the annual AMIT statement.
- Capital gains and losses can also arise when you sell units, separate from the income you receive along the way.
This is general information only, not tax advice — the treatment depends on your circumstances and the specific fund. Speak with a registered tax adviser, and see how ETF distributions are taxed in Australia for the broader picture.
Fees and what to watch
Fees matter more in bonds than in equities, because bond returns are typically lower — a fee that is a small fraction of an equity return can be a larger fraction of a bond return. It is worth modelling the long-run impact on the Fee Analyser, and comparing the close substitutes directly: IAF, VAF and AGVT.
