ASX 200 Set for Lift-Off as AI Selloff Rocks Wall Street - 24 Jun 2026

7 min read | June 24, 2026 10:06 AM AEST | By Sam

Highlights

  • Australian shares are poised for a stronger start despite heavy selling across US technology and semiconductor stocks.
  • Commodity prices weakened sharply overnight, placing pressure on mining and resource-related sectors.
  • Defensive sectors such as healthcare, utilities and consumer staples outperformed as market sentiment shifted away from high-growth technology names.

Australian shares are set for a mixed session as technology weakness, falling commodity prices and shifting interest rate expectations shape market sentiment.

Australian shares are expected to open firmer despite a turbulent overnight session on Wall Street that saw technology stocks suffer a broad-based selloff. The latest market rotation was driven by renewed concerns around artificial intelligence valuations, semiconductor demand trends and expectations of tighter monetary policy in the United States. While major US benchmarks closed lower, defensive sectors attracted strong buying interest, providing a mixed backdrop for local markets. The Australian market, represented by the ASX 200, is likely to see a divergence between defensive sectors and resource stocks following a sharp decline across major commodity markets.

AI Trade Unwinds as Technology Stocks Lead Losses

Technology shares experienced heavy selling pressure overnight as traders moved away from some of the market's strongest-performing themes.

Semiconductor companies were among the hardest hit, with memory chip manufacturers leading the decline amid concerns about future demand and valuation sustainability.

The selloff began in Asian markets before spreading through Europe and eventually reaching Wall Street.

Semiconductor Stocks Under Pressure

The semiconductor sector has been one of the strongest beneficiaries of artificial intelligence enthusiasm over the past year.

However, growing concerns surrounding:

  • Elevated valuations
  • Slowing capital inflows
  • Future memory pricing
  • Regulatory scrutiny
  • Competitive pressures

have prompted a wave of profit-taking across the sector.

Technology-heavy benchmarks bore the brunt of the selling, with investors rotating towards more defensive areas of the market.

AI Remains a Dominant Theme

Despite the pullback, artificial intelligence remains one of the most influential themes shaping global markets.

Large technology companies continue investing heavily in infrastructure, data centres and computing capacity.

However, recent trading suggests market participants are becoming increasingly selective about where future growth opportunities may emerge.

Defensive Sectors Come Back into Favour

While technology stocks struggled, defensive sectors delivered stronger performances.

Healthcare, consumer staples, utilities and real estate all finished higher as traders sought more stable areas of the market.

Healthcare Gains Momentum

Healthcare companies benefited from the broader shift towards defensive positioning.

The sector continues to attract attention because of its relatively stable demand profile and resilience during periods of market uncertainty.

Australian healthcare names could attract attention if this defensive rotation continues.

Consumer Staples and Utilities Outperform

Consumer staples and utilities often perform relatively well when market participants become more cautious.

These businesses typically provide essential goods and services that remain in demand regardless of economic conditions.

Their performance overnight highlighted the growing preference for stability over growth.

Commodity Markets Suffer Broad Selloff

One of the biggest developments overnight came from commodity markets.

A broad-based decline across metals and energy commodities created fresh challenges for resource-related sectors heading into today's session.

Copper Leads Losses

Copper prices experienced one of the sharpest declines among major commodities.

The metal is often viewed as a barometer for global economic activity due to its widespread industrial applications.

Weakness in copper may weigh on companies associated with ASX Metal & Mining Stocks when local trading begins.

Precious Metals Retreat

Gold and silver also moved lower as broader commodity selling intensified.

Although gold remains elevated compared to historical levels, overnight weakness may place pressure on precious metals producers.

Silver experienced an even steeper decline as traders reduced exposure to risk-sensitive commodity assets.

Aluminium and Strategic Metals Slide

Industrial metals were not spared from the selloff.

Aluminium and strategic metals weakened significantly as concerns surrounding global growth and manufacturing activity resurfaced.

This trend could affect sentiment across several mining and exploration companies listed on the Australian market.

Oil Prices Ease as Middle East Concerns Fade

Oil markets continued to retreat as fears surrounding supply disruptions eased.

Improved shipping activity through key energy corridors and signs of stabilising export flows contributed to weaker prices.

Energy Markets Stabilise

Recent geopolitical tensions had supported higher oil prices due to concerns about supply interruptions.

However, improving confidence around energy transportation routes helped ease those fears.

As a result, crude oil benchmarks moved lower overnight.

Impact on Energy Stocks

While lower oil prices may create short-term pressure for some producers, energy markets remain heavily influenced by broader geopolitical developments.

Companies associated with ASX Oil and Gas Stocks are likely to remain sensitive to developments across global energy markets.

Interest Rate Expectations Shift Again

Monetary policy returned to the spotlight following a major shift in expectations from leading financial institutions.

Higher-for-Longer Narrative Returns

Recent commentary from major economists suggests inflation may remain more persistent than previously expected.

This has led to renewed speculation that interest rates could remain elevated for longer.

The shift has prompted markets to reassess previous expectations surrounding future policy easing.

Bond Markets React

Government bond markets reflected the changing outlook as traders adjusted expectations around future monetary policy settings.

The prospect of tighter financial conditions has contributed to increased volatility across global equity markets.

Asian Markets Triggered the Global Selloff

The weakness seen on Wall Street was initially sparked by heavy selling across Asian markets.

South Korean Technology Stocks Tumble

South Korea's technology-heavy market experienced significant declines after concerns emerged around semiconductor valuations and speculative activity.

Given the country's importance within the global technology supply chain, the move quickly spread to other regions.

Global Markets Followed

The selloff eventually flowed into European markets before reaching US equities.

The sequence highlights how interconnected global markets have become, particularly around major themes such as artificial intelligence and semiconductor demand.

What Australian Traders Will Be Watching

Several key developments could shape today's local trading session.

Inflation Data Takes Centre Stage

Australia's latest inflation update is expected to be one of the most closely watched economic releases of the week.

The data may influence expectations around future Reserve Bank policy decisions.

Resource Stocks Face Headwinds

The sharp decline across commodities suggests miners and resource producers could encounter selling pressure during the local session.

Copper, aluminium, gold and silver all experienced substantial weakness overnight.

Defensive Shares Could Benefit

Healthcare, utilities and consumer-focused businesses may attract attention if the defensive rotation observed on Wall Street continues locally.

Corporate Developments to Monitor

Several company-specific developments are also likely to remain on market watchlists.

Infrastructure Activity

Corporate activity surrounding infrastructure assets continues generating interest across the Australian market.

Retail and Consumer Trends

Consumer-facing businesses remain under scrutiny as economic conditions evolve and household spending patterns shift.

Technology Sector Sentiment

Local technology companies could experience increased volatility as global sentiment towards growth stocks continues to fluctuate.

Final Takeaway

Global markets experienced a sharp shift overnight as the artificial intelligence trade came under pressure, triggering broad selling across technology and semiconductor stocks. While Wall Street's major benchmarks finished lower, defensive sectors such as healthcare, consumer staples and utilities attracted strong buying interest.

For Australian shares, today's session is likely to be shaped by three major themes: commodity weakness, inflation data and the continuing rotation away from high-growth technology stocks. Resource companies may face challenges following steep declines in metals prices, while defensive sectors could benefit from changing market sentiment. With inflation data due later today, traders will also be watching closely for signals that could influence the outlook for Australian monetary policy.
