Risk-off sentiment dominated Wednesday's session as the seven-month-old US-Iran conflict escalated once more, with fresh attacks on energy infrastructure and renewed Strait of Hormuz disruption pushing Brent crude above US$100 per barrel for the first time since July — a move that stoked inflation fears across global markets. The VIX rose 4.71% to 16.46 while the Nikkei VIX surged a striking 46.61% to 32.05, signalling a sharp jump in near-term anxiety in Asian volatility markets. Central bank policy divergence added further complexity, with the ECB virtually certain to deliver a 25 basis point rate hike to 2.65% on Thursday, the BoJ expected to hike next week as the yen firms toward seven-month highs, and the Fed watching Friday's US CPI print with close attention given energy-driven upside inflation risks. US Treasury yields rose across the curve, with the 10-year climbing 2bp to 4.80% — its highest since November 2023 — reinforcing the 'higher for longer' rate narrative.
For Asia-Pacific markets opening today, the combination of a triple-digit Brent price, rising US yields, and a broadly stronger US dollar creates a challenging backdrop for rate-sensitive and import-dependent economies. The ASX 200 closed down 1.00% on Wednesday and faces continued headwinds from domestic sector weakness in Financials (down 1.63%) and Consumer Discretionary (down 1.88%), though ASX Energy and gold-exposed names stand to benefit from overnight commodity strength — Brent at US$102.14 and gold at US$4,447/oz. The AUD held relatively firm at US$0.7222 (up 0.03%), supported by iron ore at US$100.02/t and China's stronger-than-expected August trade data, providing a partial offset for Australian resource exporters heading into the open.
