The closure of the Strait of Hormuz following the outbreak of military conflict with Iran on Feb. 28, 2026, is the latest example of a geopolitically driven oil supply disruption. Recent Federal Reserve Bank research quantifies the potential effects on global output, allowing detailed analysis of a range of scenarios.

The Islamic Revolutionary Guard Corps is structured into five main branches, including the Ground Forces, Aerospace Force, Navy, Quds Force, and Basij, under a command hierarchy that reports to the Supreme Leader.

Recent developments since February 2026 suggest ongoing adjustments to its operational structure in response to heightened security threats.

UNHCR estimates the Afghan national population in Iran at 4.4 million as of January 2026, encompassing both registered and unregistered refugees.
