European STOXX 600 declined 0.6% amid heightened U.S.-Iran conflict
Brent crude oil surged more than 2.6% to reach $85 per barrel, following a previous 9.6% rally
President Trump imposed a naval blockade on Iranian vessels and introduced a 20% charge on Strait of Hormuz shipments

Federal Reserve’s Waller cautioned rates could climb if inflation persists above 2%, ahead of today’s CPI release

European equity markets experienced a downturn Tuesday following renewed U.S. military action against Iran and an American-imposed maritime blockade that propelled crude oil prices to their strongest level in four weeks, unsettling investors throughout the continent.

The broad-based pan-European STOXX 600 index retreated between 0.4% and 0.6% during morning trading sessions. Germany’s benchmark DAX index declined 0.3%, while France’s CAC 40 registered a 0.6% loss, and both London’s FTSE 100 and Italy’s FTSE MIB recorded modest decreases.

The market weakness stemmed from escalating geopolitical tensions after President Donald Trump declared a naval blockade targeting Iranian maritime traffic in the Persian Gulf region. Additionally, the administration announced it would levy a 20% surcharge on all commercial freight transiting the strategically vital Strait of Hormuz.

These developments followed a third straight evening of American military operations targeting Iranian positions. The aggressive maneuvers marked a sharp reversal from what appeared to be a de-escalation period just weeks earlier, when a regional diplomatic breakthrough seemed to have quelled hostilities in the Middle East.

Crude Oil Rallies, Aviation Sector Takes Heavy Losses

Brent crude futures climbed over 2.6% to reach $85 per barrel. This advance built upon the previous session’s impressive 9.6% rally, pushing the international benchmark to its most elevated price point in approximately thirty days.

Energy sector equities emerged as one of the rare winners, advancing 1.4% as elevated petroleum prices buoyed the industry. BP shares climbed 3% following the company’s announcement that its oil trading division is anticipated to deliver modestly improved performance in the second quarter relative to the first three months of the year.

Airline stocks absorbed the most significant damage. Shares of Air France and Lufthansa each tumbled roughly 2% as climbing jet fuel expenses threatened to compress profit margins. The broader travel and leisure segment plummeted 2%, representing the steepest sectoral decline across European markets.

Monetary Policy Uncertainty Compounds Market Anxiety

Beyond Middle Eastern developments, market participants remained attentive to evolving signals regarding U.S. monetary policy. Federal Reserve Governor Christopher Waller cautioned that the central bank might be compelled to elevate interest rates should inflationary pressures persist above the institution’s 2% objective.

This positioned U.S. Consumer Price Index data scheduled for release later Tuesday as a critical focal point. Freshly appointed Federal Reserve Chair Kevin Warsh was also preparing to commence two days of congressional testimony, further amplifying market uncertainty.

Financial markets are entering the second-quarter earnings reporting period with a distinctly cautious sentiment. Several major American banking institutions were scheduled to unveil their quarterly results later in the trading day.

Stock Movers

Among individual corporate developments, Ericsson plunged 8% after the Swedish telecommunications equipment manufacturer reported quarterly revenue figures that fell short of analyst projections and issued warnings about escalating component expenses.

Evotec suffered a dramatic 30% decline after the German pharmaceutical research company slashed its 2026 financial outlook, citing delays in crucial partnership agreements that have been postponed until 2027.

Hapag-Lloyd defied the broader negative trend, climbing nearly 6% following an upward revision to its annual financial guidance.
