Europe's financial hubs are awash in green as President Trump's decision to shelve US plans for guiding ships through the Strait of Hormuz sparks a broad risk appetite revival. The Stoxx 50 jumped 1% in early trade, mirroring Wall Street's record S&P 500 close and a rallying yen, with traders pricing in a potential Iran deal to end the simmering war. Samsung's 16% bid frenzy underscores the tech-driven momentum spilling into the continent.

Yet beneath the euphoria, cracks appear: Lufthansa's Q1 loss of 612 million euros, though better than feared, underscores airlines' vulnerability to geopolitical volatility. The carrier's cautious outlook tempers optimism, as fuel costs remain elevated amid Red Sea disruptions. EU economic commissioners hailed the market lift as evidence of resilience, but warn of overexposure to US policy whims.

Geopolitical tailwinds from Trump's overtures extend beyond the Gulf. Scrapped missile plans in Germany ease fears of Russian retaliation, potentially unlocking energy deals with Moscow and stabilizing gas prices. Tech challengers like AMD and Infineon shine, with CEO interviews signaling outperformance against Nvidia amid AI hype. Novo Nordisk's earnings beat adds pharma firepower to the rally.

For EU policymakers, the surge offers breathing room to push fiscal integration, but society's broader woes—stagnant wages, migration strains—persist. As markets bet on peace dividends, Brussels must convert fleeting gains into structural reforms, lest the boom prove as ephemeral as Trump's dealmaking.
