Introduction

The current political tension between the United States and Iran focuses on a maritime blockade and its effect on Iran's ability to export oil and manage its storage capacity.

Main Body

The United States has used a blockade to seriously limit Iran's crude oil exports. According to data from Kpler, Iran is facing a crisis where it cannot move its oil, with about 1.8 million barrels per day unable to be exported. Experts claim that Iran may run out of onshore storage space between May 16 and May 20 if exports do not increase. Furthermore, stopping production for too long could cause permanent damage to Iran's oil reservoirs, leading to a lasting drop in production. To reduce these risks, Tehran has used old, large oil tankers as floating storage. However, the Iranian government is struggling to balance the need to protect its reservoirs with the need for oil revenue to fund the state. The success of the U.S. strategy depends largely on China, which has historically bought over 80% of Iranian oil. If China reduces its imports due to U.S. pressure, Iran's storage crisis will happen faster; whereas continued Chinese buying would give Iran more time. From the Iranian side, Parliament Speaker Mohammed Ghalibaf has emphasized a strategy to resist U.S. pressure. He asserted that while the U.S. has already used its own oil reserves, Iran still has options to create leverage. Specifically, he pointed to the Bab el-Mandeb strait and various pipelines as areas where Iran could cause disruptions. Additionally, Iranian officials criticized the U.S. approach, noting that oil prices often rise during the summer when demand increases, which could lead to higher market volatility.

Conclusion

The situation remains a struggle between Iran's limited oil storage and China's willingness to continue imports, balanced against Iran's ability to disrupt key global shipping routes.
