plainmoney — Market brief — Thursday 30 Jul 2026 — 06:45 AEST
The straight answer
Wall Street fell hard overnight, with the S&P 500 down 1.5% as investors reassessed the AI outlook. This risk-off mood means the ASX 200 is set for a softer open, and the Aussie dollar slipped 0.5% to 0.6953.
What's moving markets
US shares took a hit, with the S&P 500 falling 1.5% to 7,316.1, the Nasdaq down 1.7% to 24,442.9, and the Dow dropping 2.2% to 51,594.1. This broad sell-off was driven by a reassessment of the AI outlook, with chipmakers leading the decline. The VIX, a measure of market fear, jumped 13.5% to 20.7.
Despite the risk-off sentiment in equities, oil prices surged. WTI crude was up 6.9% to US$84.7, and Brent crude climbed 8.0% to US$90.8. This was largely due to escalating Middle East tensions, per SMH.com.au and Bloomberg.com. Gold also rose 2.0% to US$4,117.9 as investors sought safe haven assets.
For Australia: The ASX 200 is expected to open softer, following the lead from Wall Street. The Aussie dollar fell 0.5% against the US dollar to 0.6953, reflecting the broader risk-off move. Iron ore, Australia's top export, saw a minor dip of 0.1% to US$98.3, which could put slight pressure on the big miners.
World & geopolitics
Middle East tensions escalated, sending oil prices sharply higher, per SMH.com.au and Bloomberg.com. This matters for markets because higher oil prices can fuel inflation and impact global economic growth.
The US Federal Reserve kept interest rates on hold, as reported by Reuters. This decision, while expected, contributed to investor nerves as markets parsed comments from Fed officials.
A chipmaker slump hit global markets, with investors reassessing the AI outlook, per EnterpriseAM. This is a significant development for the ongoing AI capex cycle thread, as it suggests a potential cooling in the rapid growth seen in the tech sector.
What it means for your money
Your super will feel the pinch from the global equity sell-off, especially if you're heavily invested in international tech. Your cost of living could see upward pressure from the jump in oil prices, which translates to higher petrol costs.
What to watch
The next big catalyst is China's NBS PMI data, due this Friday (1 Aug), 11:30am AEST. This is a key read on the health of China's manufacturing and services sectors.
Possible outcomes: If the print comes in strong, it could signal improving demand from Australia's largest trading partner, potentially boosting commodity prices and the AUD. If it's weak, it could reinforce concerns about China's economic slowdown, putting pressure on the miners and the Aussie dollar.
The live indicator to watch is the iron ore price. If the PMI data is strong, expect iron ore to tick up; if weak, it'll likely soften.
Your call
The maths leans towards a cautious open for the ASX given the global risk-off mood. The surge in oil prices is a real factor for your petrol costs, but the Fed holding rates steady offers some stability. Keep an eye on that China PMI data this Friday; it's the one that could shift the dial for our commodity exports and the Aussie dollar.
