Renewed geopolitical tensions centred on the Strait of Hormuz and Iran-related developments dominated overnight sentiment, driving Brent crude up 9.31% to $83.09/bbl and WTI up 9.17% to $77.96/bbl in the sharpest single-session energy surge in recent months. This risk-off shock pushed the VIX sharply higher by 14.17% to 17.16, steepened inflation concerns across major economies, and weighed on US equities — the Nasdaq fell 1.55% as semiconductors sold off hard, while the S&P 500 dropped 0.79%. The ECB's June 25bp rate hike to a 2.25% deposit facility rate remains live policy backdrop, with its next meeting on 23 July, and Fed Chair Kevin Warsh faces congressional testimony this week following the Fed's June hold at 3.50–3.75%. US 2-year yields rose 5bp to 4.21% and the 30-year crossed 5.06%, reflecting markets repricing the inflation risk from surging energy costs.
For Asia-Pacific markets opening Tuesday, the oil spike is a double-edged signal: a clear tailwind for ASX-listed energy names and a headwind for import-dependent Asian economies, particularly Japan where USD/JPY sits at 162.43. The ASX 200 closed Monday up 0.50% to 8,806 — outperforming Wall Street — supported by Materials (+2.32%) and Financials (+0.55%), though the US selloff and gold's 2.23% drop to $4,012/oz overnight may temper early enthusiasm in gold miners today. China's trade data is due at 03:00 AEST with exports forecast at +15% YoY — a beat or miss will set the tone for iron ore and base metals sentiment across the region. The Nikkei's 1.20% gain and KOSPI's remarkable 2.52% surge from Monday's session reflect some Asia-specific resilience, but the jump in US VIX and semiconductor weakness may cap the upside at the open.
