Stoxx 600, FTSE, DAX, Iran latest, Hungary election

LONDON — European stocks began the week in negative territory as global traders assessed developments in the Middle East over the weekend.

The pan-European Stoxx 600 provisionally ended the trading session 0.2% lower, with all major bourses sliding and most sectors in the red.

The U.S. began blocking ships from entering or exiting the Strait of Hormuz at 10 a.m. ET on Monday, in an attempt to pressure Iran to reopen the key oil route.

The move was announced by U.S. President Donald Trump in a post to his social media platform Truth Social on Sunday: “Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz.”

He added: “The Blockade will begin shortly. Other Countries will be involved with this Blockade. Iran will not be allowed to profit off this Illegal Act of EXTORTION.”

Travel and leisure stocks were among the worst hit, falling 0.9%, with carriers Wizz Air, EasyJet and Lufthansa down 6.1%, 3.5% and 2%, respectively, as concerns over the supply of jet fuel to European airports rattled markets. Tui was 2.6% lower, while German aircraft engine maker MTU Aero Engines slipped nearly 1%.

In contrast, Vår Energi, the Norwegian oil and gas giant, was up almost 2% in afternoon dealmaking, as energy prices moved above $100 a barrel after Trump announced plans to blockade the Strait of Hormuz. The move was announced after talks between Washington and Tehran at the weekend failed to produce an agreement to end the Middle East conflict.

European bourses followed Asia-Pacific stocks lower on Monday as investors reacted to the breakdown of negotiations between Iran and the U.S., which has reignited fears of a prolonged conflict as crude oil prices surged. Separately, President Trump has threatened China with what he called “staggering tariffs” of around 50% should Beijing provide air defense systems, arms and other military assistance to Iran, potentially stoking tensions further.

Elsewhere, European investors are keeping an eye on Hungary after long-term conservative leader Viktor Orban conceded defeat to Peter Magyar’s pro-EU Tisza following the opposition party’s landslide election win. The victory is a blow for Russia and the Trump administration, which saw an ally in Eurosceptic Orban. Hungary’s forint rallied following the result, strengthened 2.51% against the dollar to 313.7 forint, and 2.42% against euro.

Earnings come from LVMH, Christian Dior and Galp Energia on Monday. There are no major data releases.

U.S. stocks opened lower, as the Dow Jones Industrial Average fell 247 points, or 0.5%. The S&P 500 was flat, and the Nasdaq Composite lost 0.2%.
