Escalating U.S.-Iran tensions dominated overnight macro sentiment, driving crude oil sharply higher — Brent crude surged 2.57% to USD 85.44/bbl and WTI gained 2.32% to USD 79.95/bbl — while gold extended its safe-haven bid to USD 4,056/oz (+1.48%). Despite the geopolitical backdrop, the VIX closed lower at 16.50 (-3.85%), suggesting equity markets are not yet pricing a full risk-off event, though U.S. Treasury yields rose across the curve with the 10-year climbing 6bp to 4.62% and the 30-year touching 5.10%, adding pressure to rate-sensitive assets. Central bank focus remains acute: the ECB's June 25bp hike (deposit rate to 2.25%) and the Bank of England's expected hold at 3.75% reflect divergent paths amid energy-driven inflation stickiness.
For Asia-Pacific markets opening Wednesday, the combination of higher oil, rising U.S. yields, and geopolitical uncertainty creates a mixed backdrop. The AUD caught a bid overnight, rising 0.84% to 0.6976 against the USD, supported by firmer copper (+2.13%) and precious metals, which is a mild tailwind for ASX resources names. However, the KOSPI's dramatic -8.95% fall and the Nikkei's -1.92% decline — with the Nikkei VIX still elevated at 37.23 — signal regional risk aversion that could weigh on sentiment at the open, particularly for industrials and export-oriented sectors. The ASX VIX ticked up 6.41% to 11.12, a modest warning flag that local options markets are beginning to price in slightly more near-term uncertainty.
