2026 Iran Conflict: Economic Disruption and the Closing of the Strait of Hormuz

The conflict initiated by the United States and Israel against Iran on February 28, 2026, has prompted a strategic response from the Islamic Republic: disrupting global energy supplies by attacking Gulf infrastructure and closing the Strait of Hormuz. This action has triggered a surge in global energy prices and presents significant challenges for the international economy.

Escalation and Key Events

The conflict began with wide-ranging strikes by the U.S. And Israel targeting Iran’s missile infrastructure, military sites, and leadership in Tehran and across the country . A key outcome of these strikes was the death of Iran’s Supreme Leader, Ayatollah Ali Khamenei . Following his death, Mojtaba Khamenei was appointed as his successor on March 8 .

In response, Iran has targeted Israel and U.S.-allied states in the Gulf, extending attacks to civilian sites and energy facilities . Iran has too threatened to maintain the Strait of Hormuz closed, a critical waterway for global oil transport .

Economic Impact: Rising Energy Prices

The closure, or threatened closure, of the Strait of Hormuz has had an immediate impact on global oil prices, which have risen above $100 a barrel . This increase in energy costs is contributing to broader economic disruption and concerns about inflation.

International Response

The United Nations Security Council convened on March 12, 2026, to discuss the escalating conflict and its impact, particularly on Lebanon, where clashes between Hezbollah and Israel are occurring . The UN Secretary-General has condemned the attacks by the U.S. And Israel , and many countries are urging a return to negotiations.

Casualties and Humanitarian Concerns

As of March 11, 2026, the U.S.-based group Human Rights Activists in Iran (HRANA) reported 1,825 people killed in Iran, including 197 military personnel and 1,276 civilians, with at least 200 children among the civilian casualties . Earlier, Iran’s ambassador to the UN reported over 1,300 deaths .

Looking Ahead

With Israel committed to its objectives and Iran vowing revenge, the conflict shows no immediate signs of de-escalation. The continued disruption of energy supplies and the potential for further escalation pose a significant threat to global economic stability. Finding an “off-ramp” to the conflict, as suggested by President Trump, will be crucial to mitigating further economic damage and preventing a wider regional war.
