The straight answer
Wall Street closed slightly lower overnight, with the S&P 500 down 0.2%, setting a cautious tone for the ASX open. The Aussie dollar, however, gained 0.4% to 0.7090, while iron ore held steady at US$95.2.
What's moving markets
US equities saw a slight dip, with the S&P 500 falling 0.2%, the Nasdaq down 0.3%, and the Dow off 0.2%. Small caps on the Russell 2000 bucked the trend, rising 0.5%. The VIX, a measure of market fear, eased 2.6% to 14.2. US 10-year bond yields held at 4.70%.
The Aussie dollar gained 0.4% against the greenback to 0.7090, despite mixed global risk sentiment. Iron ore prices were little changed, up 0.1% to US$95.2. Gold rose 1.7% to 4,437.3, and crude oil prices climbed, with Brent up 1.7% to US$88.5 and WTI up 1.4% to US$82.4. Bitcoin in AUD terms slipped 0.1% to 88,919.
For Australia: The ASX 200 is expected to open little changed, following the lead from Wall Street. On Friday, the ASX 200 fell 0.8% to 9,115.2. The Materials sector was hit hardest, down 2.6%, with BHP falling 3.3%, Rio Tinto 3.1%, and Fortescue 1.3%. Financials also slipped 0.1%. The AU–US 10-year bond spread remains at +32 basis points, a key factor for the Aussie dollar.
World & geopolitics
The ongoing debate around central bank interest rates continues to dominate, with The Guardian reporting on the "interest rate dilemma for central banks as inflation rises but growth slows." This highlights the tightrope central banks, including the Fed and RBA, are walking. Meanwhile, per EnergyNow, an "Iran War Splits Global Markets Into Clear Winners and Losers," suggesting geopolitical tensions are creating distinct market reactions. The "AI capex cycle" remains an active thread, with the Northern Rivers Times noting "Chinese AI Disrupts Global Technology Markets," which could impact global tech valuations and demand for commodities like copper and uranium.
What it means for your money
Your super will see global equity movements flow through, with the slight dip in US markets potentially offsetting the AUD's gain. Your cost of living could feel the pinch from rising oil prices, which directly impact petrol costs.
What to watch
The next big local data point is the AU Labour Force report this Thursday (20 Aug), 11:30am AEST. This is a key read on the health of the Australian economy and will influence the RBA's thinking on interest rates. If the unemployment rate comes in lower than expected, it could signal a tighter labour market, potentially leading to speculation about future rate hikes. Conversely, a weaker report could ease rate hike concerns. The live indicator to watch is the AUD/USD reaction immediately after the release.
Your call
The market is in a quiet holding pattern ahead of key local data. The slight dip in US equities suggests caution, but the Aussie dollar's resilience and stable iron ore prices offer some support. Keep an eye on the Labour Force report this week — it's the one that could shift expectations for the RBA cash rate and, by extension, your mortgage repayments.
