RBA warns an AI stock correction could hit Australian household spending
A Reserve Bank of Australia paper estimates how a slump in AI shares could ripple through wealth, superannuation and consumption
Australia does not have a Nvidia. Australians, it turns out, own a fair slice of the AI trade anyway.
The Reserve Bank of Australia is warning that a sharp drop in artificial intelligence stocks could weigh on the domestic economy. The channel is household wealth, and from there consumer spending.
A paper from the RBA’s domestic markets division, released on September 1, 2026, estimates that Australian households hold approximately 5.4-5.5% of their financial wealth in AI-related stocks.
Where the exposure sits
According to the RBA paper, around 1.7 percentage points of that exposure comes from shares households hold directly. The larger portion, about 3.7 percentage points, sits inside superannuation funds, Australia’s compulsory retirement savings system.
Nearly 90% of Australian households’ AI stock exposure is held in foreign markets, mostly US equities.
That means a selloff on Wall Street would not stay on Wall Street. It would show up in Australian retirement balances, even if the local share market barely moved.
What a 20% drop would do
The RBA ran the numbers on a specific scenario: a permanent 20% decline in AI stock prices.
In that case, the central bank projects a long-run reduction in household consumption of about 0.7%. If the downturn spread beyond AI and dragged on broader equity markets, the hit could potentially widen to 2.4%.

RBA officials did add an important caveat. The estimates may overstate the actual impact, because many households do not keep a close eye on how their superannuation funds are performing.
The bigger worry: debt and circular money
The RBA’s Financial Stability Review, released in October 2026, took a hard look at the rapid growth in AI investment.
The review focused in particular on areas funded by debt, such as data centers and the infrastructure that powers them. It flagged inflated valuations and lofty expectations about future earnings as key vulnerabilities.
It also pointed to circular financing practices in the sector, where companies invest in one another and buy each other’s products, which can make demand look sturdier than it really is.
The FSR warned of a potential “sharp repricing” of firms heavily invested in AI if profitability expectations are not met.
RBA Governor Michele Bullock has highlighted possible inflationary pressures stemming from AI, and has voiced concern about an “AI bubble” that could burst unexpectedly.
What this means
For Australian households, a meaningful share of AI exposure sits in super funds, so many people may be more concentrated in US tech than they realize.
Because nearly 90% of the exposure is offshore, Australian portfolios are effectively importing US market volatility. Diversification at home does not offer much protection if the risk lives in someone else’s index.
The 0.7% consumption hit from an AI-only correction looks manageable. The 2.4% figure, if a selloff spread to broader equities, would be a more serious headwind for an economy that leans heavily on household spending.
