IGB questions answered
Written from the latest data on this page. General information only, not financial advice.
How diversified is iShares Treasury ETF?
iShares Treasury ETF holds 1 securities.
Its country exposure is almost entirely Australia (100.0%), based on holdings as at 2 Sept 2026.
Which ETFs does IGB double up with most?
IGB shares the most holdings with iShares Government Inflation ETF (ILB) (95% overlap), iShares 15+ Year Australian Government Bond ETF (ALTB) (76% overlap) and iShares Core Composite Bond ETF (IAF) (44% overlap). Overlap is the share of the portfolio the two funds hold in common, looking through to the underlying securities.
At 95%, owning both IGB and ILB would mostly double up on the same investments rather than spread your money further. Of these, ALTB has the lowest fee, at 0.15% a year against 0.18% for IGB.
How is iShares Treasury ETF managed – active or passive?
iShares Treasury ETF is passively managed: it follows an index and holds what that index holds, rather than relying on a manager's stock picks.
Among Australian fixed income funds, active funds charge a median 0.43% a year and index funds 0.22%.
What will I pay in fees for IGB?
IGB charges a management fee of 0.18% a year, about $18 for every $10,000 invested. That is cheaper than 87% of the 471 ASX ETFs we track, where the median fee is 0.44%. Among Australian fixed income funds, the median is 0.24%.
Lower-cost funds with a similar focus include Vanguard Australian Fixed Interest Index ETF (VAF) at 0.10%, iShares Core Composite Bond ETF (IAF) at 0.10% and Vanguard Australian Government Bond Index ETF (VGB) at 0.16%.
If you would rather have a manager choose the investments, active options such as Betashares Australian Hybrids Active ETF (HBRD) at 0.55% and Macquarie Subordinated Debt Active ETF (MQSD) at 0.29% cost more.
The fee is taken from the fund's assets and is already reflected in its returns. You'll also pay brokerage when you buy or sell, and the bid-ask spread, which has averaged 0.04% for IGB.
Does iShares Treasury ETF follow a theme?
No. iShares Treasury ETF is a broad fixed income fund: it aims to cover a wide slice of its market (Australia) rather than one theme or sector.
What is under the hood of IGB?
As at 2 Sept 2026, the largest issuers among IGB's holdings are AUSTRALIA (COMMONWEALTH OF) RegS (88.9% across 27 bonds), Australia (Commonwealth of) (9.8% across 2 bonds) and AUSTRALIA (COMMONWEALTH OF) GREEN RegS (1.2%).
It follows an index; the issuer's PDS sets out how that index chooses and weights its holdings.
How well has iShares Treasury ETF performed?
Based on its category, iShares Treasury ETF aims mainly to pay a regular income, with capital growth secondary.
To 23 Oct 2026, with distributions reinvested, it returned −1.2% over 1 year (median 0.4%; ranked 26 of 36), 3.7% a year over 3 years (median 4.5% a year; ranked 25 of 27) and −0.1% a year over 5 years (median 1.4% a year; ranked 19 of 22). The medians and rankings compare it with Australian fixed income funds. Since listing in 2012 it has returned 2.2% a year.
Tracking difference is the gap between a fund's return and its index's return. We don't hold index returns, so we can't measure it for IGB; the issuer reports it in the monthly fact sheet. As a guide, a well-run index fund trails its index by about its fee, here 0.18% a year, and a much bigger gap is a warning sign.
Past performance is not a reliable indicator of future performance.
