Background History

The Strait of Hormuz is a critical maritime passage through which approximately 20% of the world's liquefied natural gas and 25% of seaborne oil trade passed before the current conflict. Tensions have been high since February 2026, when the United States and Israel began an air campaign against Iran, leading to a largely stalled shipping environment in the region.

The conflict in the Middle East has entered a volatile new phase as Iran-backed forces escalate their disruption of critical global shipping lanes. On Monday, the Iranian Revolutionary Guard Corps claimed responsibility for attacks on an oil tanker and other vessels in the Strait of Hormuz, a vital maritime choke point for global energy supplies. Simultaneously, Houthi rebels in Yemen announced an immediate maritime embargo against Saudi Arabia in the Red Sea, citing retaliation for a recent attack on Sanaa International Airport and a long-standing blockade on Yemen.
