You own more Nvidia than CBA.

The mental model of an Australian ETF portfolio is banks and miners with a global fund bolted on the side. The look-through says the opposite. Resolve every ETF’s holdings to the underlying companies and the offshore book, at A$148.5bn, is 65% larger than the entire ASX book at A$90.0bn. The average passive investor in this country is now more exposed to global mega-cap technology than to the Big Four combined.

Nothing illustrates the shift better than a single ranking. Sort every company, Australian or foreign, by the dollars the ETF complex holds in it, and Nvidia lands at number two, wedged between BHP and Commonwealth Bank. The largest holdings Australians have quietly stopped being only their own champions.

The offshore book is not a broad basket of the world. It is a wager on eight American companies. The Magnificent Seven plus Broadcom account for A$31bn, or 21% of the entire A$148.5bn, and once the rest of the semiconductor complex is added, Taiwan Semiconductor, ASML, Micron, AMD, roughly a third of every offshore dollar Australians hold sits in AI and the chips that feed it. This is not a criticism of the funds; it is what capitalisation-weighting a concentrated market produces. But it means the words “globally diversified”, on the tin of most international ETFs, describe a portfolio whose fate is largely a single theme’s.

Apply the intensity lens, mechanical demand as a share of each name’s ETF base, and August’s offshore cross-section rhymes with the home market to a striking degree. The names the passive bid pressed hardest were gold and defensives: precious-metals streamers Wheaton and royalty miner Agnico Eagle at the very top, alongside regulated utilities (Duke, Southern, Enbridge) and a Canadian bank. The names it pressed coolest were the crowded technology winners, Korean memory makers and the cybersecurity complex, running at a third of the median pace.

Gold and defensives led the passive bid on both sides of the Pacific. This is not an Australian quirk; it is what August’s flows did to the index everywhere Australians invest.

The median offshore name ran at 1.92% intensity, well above the home market’s 1.40%, a quiet confirmation that in August Australians pushed harder into global funds than domestic ones. The tilt within that push, though, was the same rotation seen at home: toward gold and the defensives, away from the crowded growth names that already dominate the book.

A word on how to read Part 2 against Part 1, because they are not the same instrument. At home, mechanical demand is a genuine market force: local ETFs are a meaningful marginal buyer of ASX stocks, so the bid moves prices and the signal is tradeable. Offshore it is not. A$140m of monthly Nvidia demand is a rounding error against a company worth trillions; Australian flows do not move Nvidia. So Part 2 is not a demand signal. It is an exposure and crowding lens, and on that basis it earns its place:

• Know the real portfolio. The look-through is the only way to see what an Australian’s diversified ETFs actually own. The honest answer is: a large, concentrated, single-currency bet on US technology.
• Measure the crowding you inherit. Breadth offshore is extreme, Alphabet and Nvidia sit in 60-plus funds each. The same name arrives through dozens of “different” products, so apparent diversification hides a single concentrated position.
• Watch the theme, not the ticker. With a third of the book in AI and semiconductors, the risk that matters to an Australian passive investor is not a stock, it is a theme derating. This lens sizes that exposure precisely.
