ASX Market Wrap: ASX 200 Seesaws After Wall Street Tech Selloff as Investors Eye Inflation Data

Key Highlights

• ASX 200 edges 0.11% higher despite weakness in technology and mining stocks

• Wall Street tech rout spills into Australia after NASDAQ falls 1.32%

• Healthcare and financial stocks provide support for the local market

• Inflation and employment data loom large for investors this week

• KPMG crisis deepens as major clients and government contracts disappear

The Australian share market spent much of Tuesday caught between two competing forces.

On one side was the drag from a bruising overnight session on Wall Street, where technology stocks came under renewed pressure. On the other was steady buying in defensive sectors such as healthcare and financials, helping the benchmark S&P/ASX 200 remain in positive territory.

By midday, the ASX 200 was up 0.11% at 8,825.5 points, while the broader All Ordinaries index was effectively flat at 9,031.1 points. The technology-heavy All Technology Index fell 1.07%, reflecting a cautious mood among growth-stock investors.

The Australian dollar slipped 0.25% to 69.84 US cents.

Wall Street’s tech stumble reaches Australia

The local market’s uneven performance followed a mixed session in the United States.

The Dow Jones rose 0.29%, but technology stocks faced heavy selling. The S&P 500 lost 0.37%, while the NASDAQ dropped 1.32%, weighed down by a 5% fall in Google and a sharp 16% decline in SpaceX.

The selloff highlights a growing debate around technology valuations as investors reassess how quickly artificial intelligence investments will translate into earnings growth.

At the same time, stronger performances across Asian markets offered some support. Japan’s Nikkei 225 gained 1.55%, while China’s Shanghai Composite climbed 1.78%. European markets also finished higher overnight.

Inflation takes centre stage

Market attention is increasingly shifting away from geopolitics and back toward economic data.

Australia’s May Consumer Price Index figures are due on Wednesday, followed by employment data on Thursday and a speech from Reserve Bank Deputy Governor Andrew Hauser.

The numbers will be closely watched after inflation proved more stubborn than expected throughout the first half of the year.

The Commonwealth Bank economics team expects headline inflation to ease slightly to 4.1%, helped by lower fuel prices. However, underlying inflation, which strips out more volatile items and remains the Reserve Bank’s preferred measure, is forecast to edge higher to 3.5%.

“There continues to be a lot of uncertainty around the extent to which businesses pass higher costs on to consumers,” CBA economists noted. “While we expect some increase in pass-through during May, the available data suggest that the more severe inflation scenarios considered in the immediate aftermath of the Middle East conflict have so far not materialised.”

Investors are also watching developments in the United States, where the Federal Reserve’s preferred inflation measure, the PCE index, is expected to show inflation remaining above target levels. That could reinforce expectations that interest rates stay higher for longer.

Healthcare and banks carry the market

Sector performance reflected a defensive tone.

Healthcare led gains, rising 0.84%, followed by financials up 0.82% and utilities higher by 0.70%.

Technology stocks were the weakest performers, falling 1.41%, while energy and materials also retreated.

Among individual stocks, Ioneer (ASX: INR) surged 19.64% after announcing strategic partnerships with South Korean institutions linked to its Rhyolite Ridge lithium-boron project in Nevada.

Telix Pharmaceuticals (ASX: TLX) climbed 4.15%, helping drive healthcare sector gains.

Meanwhile, WiseTech Global continued to recover after Monday’s heavy selloff. The logistics software giant is attempting to regain ground after Executive Chair Richard White strongly denied allegations that sparked an 18% plunge in the share price.

On the downside, Iluka Resources dropped 9.72% amid broader weakness across the materials sector, while Viva Energy slipped 1.40% despite reporting progress on refinery repairs following an April fire.

Data centres become the next infrastructure challenge

Away from share markets, another trend is beginning to capture attention.

A coalition of 40 major cities, including Melbourne, London and Phoenix, has launched the Global Urban Data Centres Pact, highlighting concerns about the growing energy and water demands of artificial intelligence infrastructure.

In Melbourne alone, data centres are projected to consume 10% of the city’s electricity by 2030 and potentially 20% by 2040.

Melbourne Lord Mayor Nicholas Reece compared the shift to the arrival of air conditioning decades ago.

“Data centres are the biggest thing to hit the energy grid since air conditioning in the 1950s,” Reece said.

“Where the rollout of air conditioning took decades, this is happening in a few short years. In the race to be smart cities, we don’t want to ruin the planet.”

The comments underline a growing challenge facing governments globally as they attempt to balance economic growth from AI with energy security and sustainability goals.

KPMG’s troubles deepen

Corporate governance also remained firmly in the spotlight.

KPMG Australia is facing one of the most serious crises in its history after a parliamentary inquiry into the misuse of confidential client information and whistleblower treatment.

Several senior leaders have departed, including former CEO Andrew Yates, former audit chief Julian McPherson and national chairman Martin Sheppard.

Interim CEO Stan Stavros acknowledged the firm’s failures.

“We did not meet the standards expected of us,” Stavros said. “Trust will only be rebuilt through sustained action and demonstrable change. We are determined to confront what went wrong, act transparently and ensure these failings are not repeated.”

The fallout continues to grow. Lendlease has terminated KPMG as its auditor after a 68-year relationship, while the Federal Government has suspended the firm from bidding for new taxpayer-funded contracts until September.

Former judge Anthony Whealy KC believes the consequences may yet intensify.

“They’ve been caught out well and truly,” Whealy said. “A suspension until September is a slap on the wrist and nothing more.”

What investors are watching next

For now, markets remain caught between resilient economic activity and lingering inflation concerns.

Fuel prices have eased, commodity prices remain relatively stable, and market volatility remains low. Yet investors know that one unexpected inflation print or a shift in central bank rhetoric could quickly change the outlook.

The next 48 hours may provide the clearest indication yet of whether Australia’s inflation battle is nearing an end, or whether higher interest rates will remain part of the economic landscape for longer than many hoped.
