Global risk sentiment remained fragile overnight as the US-Iran conflict continued to dominate macro narratives, with intraday whipsawing on Wall Street after President Trump suggested a deal to reopen the Strait of Hormuz could be days away — a claim markets are treating with increasing scepticism given its repetition without resolution. The VIX climbed 5% to 19.87, US 2-year Treasury yields jumped 7 basis points to 4.05% as traders priced in stickier inflation, and tonight's US CPI print for May — consensus at 4.2% YoY, the highest since April 2023 — looms as the week's single most important data release for global rate expectations. The ECB is widely expected to raise rates 25 basis points on Thursday morning AEST, while the RBA remains in a hawkish holding pattern with markets pricing 24 basis points of additional tightening through year-end. Central banks globally are caught in a stagflationary vice, balancing war-driven energy inflation against softening growth — a tension that will define policy paths well into H2 2026.
For Asia-Pacific markets opening Wednesday, the overnight session delivered a clear risk-off signal: the Nikkei fell 3.85% with its VIX surging 14.4% to 32.46, the KOSPI cratered 8.29%, and the SSE shed 1.70%, reflecting broad regional de-risking. Commodity markets added complexity — aluminium collapsed 9.09%, silver fell 4.50%, gold softened 1.32%, and crude oil retreated 2.27–2.67% on deal speculation, yet iron ore remains under pressure at $101/t, directly threatening ASX materials names. The AUD/USD sits at 0.7025 after a 0.21% overnight decline, compressing returns for unhedged offshore positions, while China's trade data due at 03:00 AEST and CPI/PPI prints expected mid-morning will set the tone for the ASX materials and energy open.
