European Markets Mixed: Defense Stocks Surge Amid Iran Tensions

European stocks closed mixed on Thursday, May 28, 2026, as escalating geopolitical tensions in the Middle East and Ukraine weighed on broad market sentiment, while defense and energy stocks surged on safe-haven demand and earnings surprises. The pan-European Stoxx 600 index fell 0.5%, with major bourses in London, Paris, and Frankfurt ending lower. However, Italy's FTSE MIB bucked the trend, rising 0.5% amid strong performances from defense and energy names.

Defense Stocks Rally on Geopolitical Uncertainty

Defense stocks were the standout performers, driven by heightened geopolitical risks. German tank parts maker Renk advanced 5.4%, while France's Exail Technologies and Germany's Rheinmetall popped 13.2% and 4.2%, respectively. The rally comes as investors price in increased defense spending amid ongoing conflicts in Ukraine and the Middle East. Ukrainian President Volodymyr Zelenskyy is currently in Sweden, signaling continued diplomatic efforts to secure military aid.

The geopolitical backdrop remains tense. U.S. forces launched fresh strikes in Iran, described as "measured, purely defensive" by a U.S. official, while Kuwait activated air defenses against missile and drone threats. Oil prices jumped 3% after Iran threatened to control the Strait of Hormuz, a critical chokepoint for global oil shipments. U.S. President Donald Trump stated he will not permit Iran to control the strait as part of any deal, while Secretary of State Marco Rubio noted progress in negotiations but acknowledged challenges.

Energy and Travel Stocks Shine

Polish energy giant Orlen reported a 22.8% jump in first-quarter adjusted core profit, with EBITDA beating analyst expectations, sending its shares higher. The strong performance reflects higher oil prices and robust demand. Meanwhile, Spain's eDreams soared 11.3% after posting a €52.2 million profit for its fiscal fourth quarter, signaling a strong rebound in travel demand.

Luxury Sector: Brunello Cucinelli Bucks the Trend

In the luxury sector, Brunello Cucinelli reported 14% revenue growth in the first quarter, defying industry headwinds. CEO Riccardo Stefanelli emphasized a long-term approach, stating, "We have to think on a long term instead of the short term imposed by the stock exchange." The Italian house consciously operates at lower margins to preserve a healthy supply chain and "gracious" growth, a strategy that continues to resonate with investors.

Financial Technology: BIS Project Agorá and Polymarket

In financial technology, the Bank for International Settlements (BIS) released findings from Project Agorá, a two-year experimental initiative demonstrating that cross-border wholesale payments can settle in seconds using tokenized central bank reserves and commercial bank deposits. The project involved seven central banks and over 40 regulated financial institutions. The prototype uses a two-layer blockchain architecture, achieving atomic settlement and reducing credit and settlement risk. Participating central banks include the Banque de France, Bank of Japan, Bank of Korea, Bank of Mexico, Swiss National Bank, Bank of England, and the Federal Reserve Bank of New York.

Separately, Polymarket clarified that it is not adding mandatory KYC checks to its existing service, following reports that the prediction market platform had considered user verification. Vice president of engineering Josh Stevens stated that identity checks are required only for a new beta product and will not be extended to the main platform. This comes as Polymarket faces widening access restrictions, including blocks in Brazil and Spain.
