Global financial markets responded nervously on Monday after the United States launched a series of airstrikes on Iranian nuclear and military facilities over the weekend, sparking fears of broader regional instability and a potential disruption to global oil supplies.
Brent crude rose 1.53% to $78.19 a barrel, while West Texas Intermediate (WTI) climbed 1.48% to $74.93 as of early Monday morning in Europe. The price surge came as tensions between Washington and Tehran intensified, raising concerns over the security of energy supplies through the Strait of Hormuz—a vital oil transit chokepoint.
The strikes marked a significant escalation in the ongoing conflict, which began with Israeli attacks on Iran earlier this month. U.S. President Donald Trump defended the action, stating that Iran must never be allowed to acquire a nuclear weapon. In response, Iranian President Masoud Pezeshkian vowed, “Iran will never surrender to bullying and oppression.” Meanwhile, Iranian Foreign Minister Abbas Araghchi arrived in Moscow for talks with Russian President Vladimir Putin, as diplomatic efforts ramped up.
European markets opened in negative territory. London’s FTSE 100 slipped 0.28% to 8,749.98, while France’s CAC 40 fell 0.66% and Germany’s DAX dropped 0.55%. Italy’s FTSE MIB posted the sharpest fall among major European indices, down 0.97%.
Broader indices across Europe also felt the impact. The pan-European STOXX 600 declined 0.28% and the EURO STOXX 50 dipped 0.26%.
U.S. futures mirrored the cautious sentiment. The S&P 500 was down 0.13%, while the Dow Jones Industrial Average futures dropped 0.2%. Nasdaq futures declined 0.18%, reflecting investor unease as markets opened for the week.
Asian markets were mixed. Japan’s Nikkei 225 lost 0.19%, South Korea’s Kospi fell 0.3%, and Australia’s ASX 200 dipped 0.37%. However, Hong Kong’s Hang Seng rose 0.35% and Shanghai’s Composite Index edged up 0.13%.
With Iran being a major oil producer and located along the critical Strait of Hormuz—through which roughly one-fifth of the world’s oil passes—investors are bracing for possible retaliatory actions. While shipping giant Maersk confirmed continued operations through the strait, vessel tracking showed that two supertankers made abrupt U-turns there on Sunday, suggesting growing operational risks.
Analysts say Iran is unlikely to close the Strait of Hormuz entirely, as it remains essential for its own oil exports, primarily to China. However, any interference in shipping lanes or attacks on regional oil infrastructure could trigger further price spikes and fuel market volatility.
In a post on Truth Social, President Trump hinted at possible political changes in Tehran, writing: “If the current Iranian regime is unable to make Iran great again, why wouldn’t there be regime change?” His comment appeared to contradict earlier assurances from Vice President J.D. Vance, who said regime change was not the administration’s goal.
For now, markets remain on edge as the world watches for Iran’s next move.
