Australian share prices plummet $45bn after Trump recession fears tank US market

The Australian share market has plummeted, shedding more than $45bn after US markets tanked overnight on recession fears.

The benchmark S&P/ASX200 dropped more than 140 points, or about 1.79%, to 7820.1 after jumping off a cliff at the start of Tuesday’s session.

The broader All Ordinaries index was down about 1.9%, or 156.4 points, to 8035.3 points.

The main index lost as much as $45bn in market value, from Monday’s close of $2.6tn, in the first half of the trading day.

US president Donald Trump’s on-again, off-again tariffs have fanned investor uncertainty at a time when the growth outlook of the world’s largest economy is being questioned.

“The market’s reacting at the moment to a number of factors, but things like concerns of Trump’s tariffs, that this could trigger an economic slowdown,” Steven Daghlian, a CommSec market analyst, said.

“The unpredictability of the trade war was something that really weighed on markets last week.”

On Sunday – and in the wake of weaker than expected US jobs and inflation data – Trump could not say if his protectionist policies could lead the US into a recession, sending shockwaves through global markets.

China’s retaliatory tariffs on select US imports are set to take effect by Monday. At the same time, US Congress is scrambling to agree to a spending bill to avoid a government shutdown.

On Wall Street, the S&P500 lost 155.21 points, or 2.69%, to end at 5,614.99 points, while the tech-heavy Nasdaq Composite lost 726.01 points (3.99%) to 17,470.21. The Dow Jones Industrial Average fell 890.63 points (2.08%) to 41,911.09.

The tech sell-off impacted the so-called “Magnificent Seven” stocks of Amazon, Apple, Meta, Google owner Alphabet, Microsoft, Nvidia, and Tesla, all down more than 5%.

Tech stocks account for roughly a third of the US share market and the Magnificent Seven alone had a combined valuation of US$18tn (A$29tn) in February, greater than the GDP of any nations except the US and China.

“When you have seven stocks that are so large and have such a significant weight on an impact on the broader market, you know that’s obviously a risk,” Daghlian said.

All 11 Australian sectors on the local bourse were in the red, led by IT stocks which fell by 4.9%.

The resource sector and financials, which account for more than half of Australia’s share market by company size, were down 2.0% and 1.7% respectively.

Consumer discretionary stocks fell more than 2%, while industrials, real estate and health care stocks were all down more than 1% by midday.

The Australian share market slumped about 8.1% from reaching an all-time-high of 8615 on 14 February.

“Yes, we’re down heavily, but this is after record highs just weeks ago,” Daghlian said.

The Australian dollar was buying 62.68 US cents, down from 63.16 on Monday afternoon.
