Tech Volatility Hits Global Markets as Rate Hike Fears Grow
Key Metrics
- ASX 200: +18.4 points (+0.2%) to 8,805.4
- S&P 500: -1.4% (vs +11 weekly gains in last 12 weeks)
- Nasdaq: -2.2%
- Tech sector (S&P 500): +25.5% (3 months), +16.6% (YTD)
- Interest rate hike probability: 85% (vs 60% a week earlier)
The Australian sharemarket staged a modest rebound while technology stocks continued to roil global markets, with growing expectations of interest rate hikes by year-end prompting investors to reassess high-flying tech valuations.
Tech Sector Turmoil
Wall Street's benchmark S&P index fell 1.4%, dragged down by technology stocks that have driven much of the market's gains this year. The Nasdaq composite dropped 2.2%, while the Dow Jones, less influenced by tech, was down just 0.1%. In Asia, South Korea's Kospi has nearly doubled so far in 2026 despite Tuesday's plunge.
Australian tech stocks rebounded Wednesday morning after Tuesday's heavy losses:
- WiseTech: +5.2%
- Xero: +4.3%
- Technology One: +1.8%
- NEXTDC: +1.5%
However, the broader tech sector remains under pressure as concerns mount about potentially higher interest rates by the end of 2026.
Mining and Resource Declines
Mining stocks lost ground across the board:
| Company | Change | YTD Performance |
|---|---|---|
| BHP | -1.1% | -2.3% |
| Fortescue | -0.4% | +8.7% |
| Rio Tinto | -2.2% | -1.5% |
| Northern Star | -1.0% | -5.2% |
| Evolution Mining | -2.2% | -12.4% |
Gold miners fell as the precious metal dropped below $US4,100 per ounce, prompting investors to cut bullion holdings to cover losses elsewhere in their portfolios. The tech-led sell-off on Wall Street has created portfolio rebalancing pressures across commodity markets.
Financial and Energy Sectors
Financial stocks showed mixed performance:
- Commonwealth Bank: +0.7%
- National Australia Bank: +0.8%
- Westpac: -0.1%
- ANZ Bank: -0.6%
Energy stocks slid lower as oil prices extended declines in early Asian trade:
- US crude: -0.6% to $US72.76
- Brent crude: -0.5% to $US76.66
- Woodside Energy: -1.5%
- Santos: -0.5%
- Ampol: -0.4%
- Viva Energy: -2.2%
Space Exploration outlier
SpaceX, which had a soaring market debut less than two weeks ago, wavered in early trading then closed 1% higher. The space exploration and artificial intelligence company plans to raise money through a bond offering, partly to fund AI development.
Interest Rate Expectations
The Federal Reserve has signaled it could raise interest rates at least once before the end of 2026. Wall Street now sees an 85% chance that the central bank will raise its benchmark interest rate this year, compared to 60% a week earlier, according to data from CME Group.
"Viewed through this lens, a period of consolidation is reasonable, in our view, after such a sharp move higher," wrote Brock Weimer, investment strategy analyst at Edward Jones, in a research note.
Inflation and Market Impact
Inflation has been heating up throughout 2026, with tariffs helping halt and reverse what had been an easing of inflation growth. The US war with Iran has pushed energy prices higher, including gas prices. Higher energy costs have also made shipping more expensive for a wide range of goods, weighing on businesses and households.
A report due Thursday with an inflation measure preferred by the Fed is expected to show that inflation rose to 4.1% in May.
International Developments
Chinese tech and e-commerce giant Alibaba sued the US Department of Defence for designations including saying it was a "Chinese military company," according to a court filing.
"The determinations have no basis in fact or law," Alibaba said in its lawsuit. "Its products and services are built for retail, logistics, and enterprise information technology—not weapons, defence, or intelligence."
Watch Points / Risks
- Interest rate trajectory: The Fed's potential rate hikes could continue to pressure tech valuations
- Geopolitical tensions: US-Iran conflict and trade disputes may further impact energy prices and supply chains
- Tech sector rotation: Continued rotation from growth to value stocks could persist
- Inflation persistence: Persistent inflation may force more aggressive monetary policy
- Portfolio rebalancing: Ongoing rebalancing by institutional investors could create volatility
