The dominant overnight macro driver is the first direct US-Iran military exchange in over a month, with US forces striking Iranian rocket launchers on Larak Island in the Strait of Hormuz on 30 August and Iran retaliating against US positions in Jordan and the UAE. Brent crude surged to $90.49/bbl (+1.32%) and WTI to $85.76/bbl (+2.83%), while Dutch TTF front-month gas topped €70/MWh for the first time since March (+4.91%), compounding energy market stress at a moment when EU gas storage sits below seasonal norms at ~64.7% full. Separately, Fed Chair Kevin Warsh's hawkish remarks at Jackson Hole on 28 August pushed the probability of a September Fed rate hike to ~57%, driving the US 2-year yield up 14bp to 4.34% and the 10-year up 6bp to 4.73%, steepening the global tightening narrative and lifting the DXY 0.27% to 99.43.
For European markets, the combined oil and rate shock creates a bifurcated picture heading into Tuesday's open. The EUR/USD fell 0.57% to 1.1589, reflecting both USD strength on Warsh's comments and risk-off positioning tied to Hormuz escalation; GBP/USD slipped 0.42% to 1.354 with EUR/GBP down 0.15% to 0.8558, suggesting sterling held marginally better on the crosses. The DAX closed down 0.41% to 26,258 and the FTSE 100 fell 0.79% to 10,792, while the Euro Stoxx 50 ended flat at -0.07% as southern European bourses — IBEX 35 +0.47%, MIB +0.67% — outperformed on financial-sector strength. Energy producers and utilities face a complex backdrop of elevated spot prices versus demand destruction risk, while industrials, chemicals, and autos are most exposed to surging input costs; financials present the notable counterweight, with the ECB widely expected to deliver a 25bp hike on 10 September and European Financial Services the session's top-performing sector at +2.45%.
