There aren't too many exchange-traded funds (ETFs) on the ASX that I would describe as 'safe'. It would be irresponsible and downright untruthful. Any ASX ETF that holds underlying shares within it is, by definition, an investment that does not guarantee capital protection.
Whilst it is still, at least in my view, a great idea to invest in share-based ETFs for long-term wealth creation, investors must do so with the understanding that there is always a chance they will permanently lose capital. It's an issue that particularly vexes retirees and other investors who rely on the share market to generate income. After all, if your primary source of income is no longer active, it is exceedingly difficult to overcome a capital loss.
That's why I would recommend the BetaShares Australian High Interest Cash ETF (ASX: AAA) to anyone looking for a truly safe, income-producing investment today.
AAA is not an ASX ETF that invests in stocks. Instead, it holds a portfolio of cash assets, which mainly consist of interest-bearing cash deposits with established banks and financial institutions. These include National Australia Bank Ltd (ASX: NAB), Bank of Queensland Ltd (ASX: BOQ), Rabobank, and Bendigo and Adelaide Bank Ltd (ASX: BEN). It also holds accounts with international banks like JPMorgan Chase, Citibank, and Sumitomo Mitsui Banking Corporation.
Until recently, I would not have advocated this kind of ETF to most investors. Cash is an asset class that has historically underperformed shares. That's the trade-off for that increased capital protection.

A safe ASX ETF with a 4% yield?
However, we are not living in conventional financial times. Interest rates are at a 15-year high, yet the share market is also bobbing along at record highs of its own. An historically unusual situation. As such, the yield one can obtain from a truly safe cash investment is, at least right now, matching or even outstripping the dividend income available from many ASX shares.
Many income investors might find this particularly appealing. Many wouldn't wish to risk their capital by investing in shares at all-time highs when an inflation-beating yield from a cash investment is on the table.
Let's look at the Betashares Australian High Interest Cash ETF to illustrate. This ASX ETF happens to pay out dividend distributions monthly. Over the past 12 months, AAA has doled out a total of $2.02 per unit in dividend distributions. These have ranged from 15.24 cents per unit to 19.52 cents per unit. The higher payments have come in more recent months, reflecting the three interest rate increases we've seen in 2026 so far.
At the current unit price of $50.12, that gives this ASX ETF a trailing dividend distribution yield of 4.03%. If we annualise AAA's most recent monthly payout of 18.89 cents per unit, we get an annualised yield of 4.52%.
Foolish Takeaway
This ASX ETF will protect investors' capital. Case in point, AAA units have only moved 0.21% higher since 2012. The most investors have lost at any point since then has been about 0.4%. And that was a very short-lived fluctuation. The only factor that can meaningfully influence this ETF's returns is interest rates, which will cause AAA's dividend distributions to rise or fall accordingly.
With what is (at least for now) a 4% yield, well above many ASX blue-chip dividend yields, I think this ASX ETF is well worth a look for any income investors today.
