European benchmarks extended their slide on Tuesday as Iran shifted to an offensive military posture and Washington ruled out a ceasefire extension. The Stoxx Europe 600 marked a sixth straight session of declines, on track for its longest losing streak since November 2025, while Brent crude surged to its highest level since July 30, above $91 a barrel.
The pan-European Stoxx Europe 600 Index inched 0.2% lower on Tuesday, marking its sixth consecutive session of declines and its lowest level since August 5. If the losses hold through the close, the benchmark locks in its longest daily losing streak since November 2025.
Germany's DAX dropped 0.4%, while France's CAC 40 and London's FTSE 100 traded flat.
Iran shifts to offensive posture
Geopolitical friction reached a new tipping point after Reuters reported Tehran announced a pivot to a fully offensive military posture following a total breakdown in negotiations for a permanent end to the war. Citing Iranian officials, Reuters said Tehran discarded defensive constraints after Washington explicitly ruled out extending a temporary framework ceasefire that expired this week.
The shift raises fears of direct strikes on regional energy facilities and maritime transit corridors, extinguishing remaining hopes for a diplomatic resolution and sending risk premiums surging across global commodity and currency hubs.
Crude surges above $91
The escalation triggered a fresh leg higher in energy markets. Brent crude futures surged 0.8% to $91.49 a barrel, their highest level since July 30.
That renewed surge threatens to reignite cost-push inflation across European supply chains. Desks worry a prolonged energy shock could limit central banks' ability to deliver monetary easing this autumn, even as regional growth stays fragile.
Earnings tailwind fizzles
Through June and July, a robust European reporting season fueled the Stoxx 600's charge to record peaks, with surging bank profits, resilient luxury margins and strong energy beats giving desks reason to buy dips. Now, with the Q2 cycle largely behind it, that earnings tailwind has fizzled and the equity risk premium sits near 25-year lows, leaving the market exposed to macroeconomic shocks. That has forced trading desks to rely entirely on top-down geopolitical headlines.
