The dominant macro driver overnight was an escalating US-Iran military confrontation in the Strait of Hormuz, where tit-for-tat tanker attacks pushed Brent crude above $100 per barrel for the first time since July, settling at $101.21 — a move of 3.36% — while WTI rose 3.25% to $96.05. The oil shock has reignited inflation fears globally, lifting US 10-year Treasury yields to approximately 4.80–4.85%, their highest level since late 2023, and German 10-year bunds to their highest since 2011. The ECB is widely expected to hike its main refinancing rate 25 basis points to 2.65% at today's decision, the Fed carries roughly 60% market-implied odds of a 25bp hike at its September 15–16 meeting per CME FedWatch, and the BoJ is expected to move next week — a simultaneous global tightening impulse not seen in years. Risk sentiment deteriorated broadly, with the VIX rising 4.71% to 16.46 and Wall Street closing lower across all major indices, the sole exception being the energy sector.
For Asia-Pacific markets opening Thursday, the cross-asset picture is cautious but nuanced. The oil spike is a direct terms-of-trade headwind for energy-importing economies including Japan and parts of Southeast Asia, while Australia — as a major energy and commodity exporter — faces a more mixed but broadly supportive commodity backdrop, with gold at $4,416/oz (+0.50%), copper at $6.80/lb (+0.96%), and platinum surging 3.58%. The ASX 200 had already shown relative resilience, closing down just 0.11% versus falls of 1.31–1.94% across European bourses, with its VIX actually declining 1.84% to 11.75, signalling domestic calm. China's August inflation surprise — CPI +0.8% y/y and PPI +3.8% y/y, both above consensus and energy-driven — adds to the global reflation narrative and will be watched closely for implications on Chinese demand for Australian bulk and energy commodities. Investors should monitor today's ECB decision and Lagarde press conference at 08:45 ET, US PPI data at 08:30 ET, and any further Strait of Hormuz developments as the primary catalysts likely to set the tone for Friday's ASX open.
