Escalating Middle East hostilities remain the dominant macro driver, with Iran-backed Houthi attacks on Saudi energy infrastructure and renewed threats to the Strait of Hormuz pushing Brent crude to six-week highs near $99–100 per barrel and amplifying global inflation concerns now seven months into the US-Iran conflict. Bond markets responded sharply, with the US 10-year yield briefly breaching 4.80% before settling at 4.78%, and central bank pricing shifting decisively hawkish — markets now assign roughly 60% odds to a Fed 25bp hike on 16 September, with the ECB widely expected to deliver its own 25bp move on 10 September and the BoJ seen as highly likely to hike on 18 September amid a surging yen. The VIX ticked up 2.75% to 15.72, reflecting the market's unease, though overall fear gauges remain contained relative to the scale of the geopolitical shock. Gold held near $4,398/oz and copper hit fresh records on a combination of safe-haven demand, tariff concerns, and AI-driven supply anxiety.
For Asia-Pacific markets opening Wednesday, the cross-asset picture is cautiously mixed: oil at these levels is a double-edged sword — a tailwind for ASX energy names but a headwind for import-dependent economies and rate-sensitive equity sectors. The yen's strength on BoJ hike expectations pressured the Nikkei overnight (down 1.7% in the prior session) though South Korea's KOSPI surged 4.61%, standing out as the region's clear outperformer. The ASX closed barely positive at 9,010.9 (+0.06%) with energy and materials leading domestically, while the ASX VIX sits at a benign 10.56, suggesting local implied volatility remains subdued even as the global macro backdrop grows more complex ahead of a dense central bank calendar.
