President Donald Trump announced on March 16, 2026, that efforts to form a coalition to protect oil tankers in the Strait of Hormuz have stalled, as several U.S. allies remain unwilling to participate. Trump expressed frustration, stating, 'Some are very enthusiastic, and some are less than enthusiastic,' and noted that some countries the U.S. has protected for decades are reluctant to join the mission [1]. He declined to name which nations have agreed to help, but indicated that a list of participating countries would be released soon [1].
The disruption in tanker traffic through the Strait, caused by Iranian attacks, has led to the largest oil supply disruption in history. Crude prices have surged approximately 40% since the U.S. and Israel attacked Iran two weeks ago [1]. Trump has been pressuring allies to send military forces to restore oil exports, but resistance persists. British Prime Minister Keir Starmer was hesitant to send two aircraft carriers at the U.S. request, stating that reopening the Strait 'is not a simple task' and emphasizing the need for a coordinated plan with allies to restore freedom of navigation in the Persian Gulf [1].
French President Emmanuel Macron has signaled support for restoring navigation, with France deploying an aircraft carrier strike group to the Eastern Mediterranean. However, the French Foreign Ministry clarified that the carrier remains in a defensive posture and its status has not changed [1]. German Chancellor Friedrich Merz stated that Berlin will not participate in any mission in the Strait as long as the war continues [1].
Trump remains confident in U.S. capabilities, saying, 'We don't need anybody. We're the strongest nation in the world,' but continues to seek broader international involvement. The ongoing disruption has significant implications for global oil markets, with prices sharply higher and uncertainty about when normal tanker traffic will resume [1].
CONCLUSION
Efforts to form an international coalition to secure the Strait of Hormuz have been hampered by reluctance among key U.S. allies, contributing to a historic oil supply disruption and a 40% surge in crude prices. The situation remains fluid, with the U.S. poised to announce participating nations and allies working on plans to restore stability. Market uncertainty persists as the coalition's readiness and the reopening of the Strait are unresolved.
