Best Bonds & Fixed Income ETFs on the ASX

A Bonds & Fixed Income ETF invests in a portfolio of government bonds, corporate bonds, or hybrid securities to provide regular income with lower volatility than equities. On the ASX, popular options include VAF (Vanguard Australian Fixed Interest), IAF (iShares Core Composite Bond), and VACF (Vanguard Australian Corporate Fixed Interest). These ETFs hold hundreds of individual bonds, providing diversification across issuers and maturities that would be impractical for retail investors to replicate directly in Australia's OTC bond market.

Focus on duration - a measure of interest rate sensitivity - since higher-duration funds like VAF (approximately 5–6 years) lose more value when RBA rates rise than short-duration alternatives like VSO or RSM. Compare the yield-to-maturity against the management fee to understand net income: if the ETF yields 4.5% but charges 0.20%, your net yield is roughly 4.3%. Assess credit quality (government vs investment-grade corporate vs sub-investment-grade), currency hedging for global bond ETFs like VBND, and whether distributions are monthly or quarterly for cashflow planning.

Duration measures how much a bond ETF's price moves for each 1% change in interest rates - a fund with 5-year duration loses approximately 5% in capital value if rates rise 1%. When the RBA hiked rates aggressively in 2022–2023, VAF fell roughly 10% despite being a 'defensive' asset, shocking many conservative investors. Conversely, when rates fall, longer-duration funds deliver capital gains on top of yield. Australian investors should match duration to their investment horizon and consider short-duration ETFs like RSM (1–2 year duration) if rate cuts are uncertain.

Key risks include duration/interest rate risk, credit risk (corporate bond defaults), and inflation risk eroding real returns if yields don't keep pace with CPI. Bond ETF distributions are generally unfranked, making them less tax-efficient than franked equity income for Australian taxpayers - though they can suit accumulation-phase super funds. These ETFs are appropriate for conservative investors, retirees seeking capital preservation with steady income, and those building diversified portfolios with a defensive allocation to offset equity volatility.
