International discussion has intensified over whether the United States’ ongoing economic and naval sanctions can effectively stop Iran’s oil exports. Iranian Parliament Speaker Mohammad Bagher Ghalibaf stated that despite the sanctions, no major damage has occurred to Iran’s oil fields and the country is prepared to withstand economic pressure for at least 30 more days. The US, however, maintains that its sanctions are working, arguing that if Iran cannot export oil, storage limits will eventually force production cuts.

Satellite data show that since the sanctions began on April 13, Iran’s oil storage has risen sharply. By April 20, storage tanks on Kharg Island—through which about 90 percent of Iran’s oil exports pass—were 74 percent full, with an additional three million barrels added, according to the Center on Global Energy Policy. Analysts note that oil companies typically avoid filling storage beyond 80 percent for safety reasons.

Experts suggest that while the sanctions are increasing pressure, they are unlikely to halt production immediately. Instead, Iran may face a gradual slowdown leading to a prolonged economic strain.
