The United States' efforts to choke off Iran's oil exports through the Strait of Hormuz are facing new challenges as attacks on critical bypass routes and other shipping lanes threaten to disrupt global energy supplies. A drone attack last week significantly damaged Saudi Arabia's East-West Pipeline, a key conduit for crude oil to the Red Sea, which could be out of service for up to five weeks. In parallel, Iran-backed Houthi rebels have increased their control over strategic islands in the Bab el-Mandeb Strait, a vital link between the Red Sea and the Gulf of Aden.
These disruptions are already impacting American consumers, with U.S. diesel prices reaching a national average of $6.23 a gallon and regular gasoline averaging $4.32. Brent crude climbed to approximately $110 a barrel amid the escalating tensions.
Washington has implemented sharp restrictions on Iran's oil exports and trade. However, the conflict continues to affect energy supplies across the region, particularly with the Houthi rebels solidifying their positions along Yemen's coast. This situation raises concerns about increasing costs for everyday goods, shipping, and housing.
Iran's crude oil exports have seen a dramatic reduction. Since the U.S. reinstated its naval blockade on July 14, no Iranian crude cargoes have reportedly reached China, Iran's primary oil customer. Loadings of Iranian crude and condensate fell to an estimated 220,000 to 255,000 barrels per day in August, a sharp decline from approximately 740,000 in July and 2 million in March.
Commercial shipping traffic through the Strait of Hormuz also remains heavily disrupted. Data tracking global commodity flows and maritime shipping has indicated very low numbers of visible commodity-vessel transits in recent weeks. Experts suggest that the combined pressure of sanctions, the naval blockade, and increasing diplomatic isolation is beginning to affect Iran's broader economy beyond its oil industry. Restrictions on trade channels with the United Arab Emirates and Turkey are reportedly making it more difficult for Iran to obtain foreign currency and essential imports.
Gasoline availability could become a significant pressure point for Iran, which, despite being a major crude producer, lacks sufficient refining capacity and relies on imports. While the Iranian regime can partially offset financial blows by printing currency and paying salaries, physical shortages of goods like gasoline are more challenging to resolve. Miad Maleki, a senior fellow at the Foundation for Defense of Democracies, noted that while Iran can print its currency, it cannot print gasoline.
Experts caution against viewing every Houthi action as a direct, coordinated Iranian strategy to shift leverage from the Strait of Hormuz to the Bab el-Mandeb. Arash Azizi, an Iran expert, stated that Tehran's ability to control the Strait of Hormuz has diminished, and while Iran supports the Houthis, it does not exercise full operational control over the group. The Houthi expansion around Bab el-Mandeb, including the capture of key islands, has increased their influence, yet they have permitted many vessels to pass, avoiding a complete blockade.
Azizi described the instability in the Bab el-Mandeb as a complex situation for Tehran, potentially increasing costs for adversaries but also complicating Iran's objective of ending the current conflict and beginning reconstruction. He believes Iran is prepared to make concessions to end the war and preserve the Islamic Republic, with the primary concern being the regime's survival.
The U.S. has demonstrated its ability to exert significant economic pressure on Iran. The key question remains whether this pressure will yield the desired concessions from Washington's perspective, and whether the costs imposed by Iran and its allies will ultimately improve Tehran's bargaining position or deepen its isolation. Azizi suggested that Iran's negotiating stance has softened, and the current red line for the regime is its own survival. He emphasized that Iran is experiencing significantly more economic pain than the United States due to the blockade, which has fundamentally worsened Iran's outlook by restricting trade without clear indications of when normal commercial activity might resume.
