The US–Iran conflict, now in its fourth month, reasserted itself as the dominant macro driver on Monday after fresh US and Israeli strikes and reports of Israeli troops pushing deeper into Lebanon reignited ceasefire collapse fears. WTI crude surged 5.93% to close at $92.54/bbl and Brent rose 4.24% to $97.79/bbl — partially reversing a ~20% May decline — while the IEA estimates the effective closure of the Strait of Hormuz has removed 11.1 million barrels per day of global supply since March, with Iranian crude loadings collapsing from 1.7 mb/d in March to below 0.3 mb/d in May. The VIX ticked up 4.77% to 16.05, gold fell 1.87% to $4,475/oz as risk appetite rotated into equities, and Bitcoin slid 3.07% to $71,320 — a pattern consistent with a geopolitical risk re-pricing rather than a broad flight to safety.
For European markets opening Tuesday, the oil spike is a stagflationary headwind: the DAX fell 0.40%, FTSE 100 dropped 0.68%, and the IBEX 35 was the worst performer among major indices at -0.97%, reflecting Spain's elevated energy import sensitivity. European sector data confirms the pressure is concentrated in Construction (-2.20%), Industrials (-2.12%), Healthcare (-1.34%) and Insurance (-1.01%) — all cost-sensitive to energy inputs or exposed to broader economic slowdown — while Chemicals (+1.70%) and Basic Resources (+1.40%) outperformed, benefiting from commodity price pass-through. The SMI's -1.75% decline stands out as the sharpest national index loss, consistent with its defensive, healthcare-heavy composition facing sector-specific selling. EUR/USD slipped 0.03% to 1.1649 and EUR/GBP edged down 0.05% to 0.866, with the modest EUR softness reflecting ECB hike uncertainty and energy import cost pressure, while GBP/USD's +0.06% gain to 1.3452 suggests relative UK resilience; USD/CHF fell 0.23% to 0.7819, with the franc's strength against the dollar contrasting with the SMI's equity weakness and pointing to safe-haven FX demand running alongside equity outflows from Swiss-listed defensives.
