Oil prices surged past $100 a barrel on Monday, March 9, 2026, as escalating tensions in the Middle East threaten critical shipping lanes and fuel concerns about global supply disruptions. The price increase follows attacks on vessels and a de facto closure of the Strait of Hormuz, a vital waterway for global energy markets.
Iran has challenged the United States to deploy warships to escort tankers through the Strait of Hormuz, according to reports from Iranian state media. A spokesperson for Iran’s Revolutionary Guard stated, “We welcome the escort of tankers and the presence of American forces during the passage of the Strait of Hormuz. We are actually waiting for their arrival.” The statement, reported by BFMTV, comes as Washington considers a $20 billion plan to reassure shipping companies despite persistent risks.
The conflict in the Middle East has already disrupted maritime traffic and energy exports via the strait, which handles approximately 20% of the world’s oil supply. At least nine ships have been attacked since fighting in Iran began over the weekend and the Revolutionary Guard ordered vessels to avoid the crucial shipping route.
U.S. President Donald Trump indicated on Tuesday, March 3, 2026, via Truth Social that the U.S. Navy could begin escorting tankers through the Strait of Hormuz if necessary. But, threats from Iran to attack any ships in the region are overshadowing these assurances, as highlighted by CNN. Commercial seafarers express continued safety concerns, with zero tankers transiting the Strait of Hormuz on Wednesday, March 5, 2026.
Major shipping lines, including Maersk and Hapag-Lloyd, have already suspended accepting most cargo destined for Persian Gulf countries. The situation is prompting fears of a “stagflationary shock” for Europe, according to RTL.fr, with Nobel laureate in economics Philippe Aghion predicting a resurgence of inflation and a slowdown in economic growth.
French President Emmanuel Macron has emphasized the need for Iran to guarantee freedom of navigation by ending the effective closure of the Strait of Hormuz, France24 reported. Meanwhile, French authorities are working to calm consumers and markets, according to Le Figaro.
The situation underscores the sensitivity of global energy markets to geopolitical instability. The disruption in the Strait of Hormuz is reminiscent of past incidents, such as the 1987 fire on the American supertanker Bridgeton, as noted by the Iranian spokesperson. The current crisis is likely to keep investors focused on supply chain vulnerabilities and potential inflationary pressures.
