The United States has recently increased the flow of non-Iranian oil through the Strait of Hormuz, reversing a blockade established by Iran at the start of the conflict in February 2026. While the U.S. military has facilitated greater exports for Gulf countries, a U.S. blockade has simultaneously reduced Iran's own oil exports to roughly 255,000 barrels a day in August, down from 1.85 million in the spring. Despite these shifts in maritime control, the war involving the U.S., Israel, and Iran continues without a clear diplomatic resolution.
The current conflict began in February 2026 and was originally intended by U.S. and Israeli planners to last only a few weeks. A diplomatic agreement reached in June collapsed shortly after its signing, leading to a return to low-level fighting and persistent economic tension. Iran had initially used its control over the Strait of Hormuz, where 20% of global oil and gas transits during peacetime, to pressure the global economy while maintaining its own exports to China.
According to data from trade monitor Kpler, non-Iranian oil exports through the strait rose to 8.4 million barrels a day in September, up from 300,000 at the peak of the Iranian blockade. U.S. Energy Secretary Chris Wright stated on Sunday, September 6, that flows have returned to approximately two-thirds of pre-conflict levels. However, maintaining this traffic requires a significant U.S. military presence that officials say is straining resources. The war has resulted in the deaths of 18 U.S. service members and cost U.S. taxpayers over $37.5 billion.
The scale of the economic impact is significant, with Iran's oil exports falling by approximately 86% since the spring, dropping from 1.85 million to 255,000 barrels per day. This reduction has caused severe domestic strain in Iran, where citizens are facing long lines at gas stations and rising prices for basic goods. Meanwhile, the Houthi group in Yemen has expanded the conflict by attacking Saudi Arabian oil infrastructure, including the Jizan refinery. These attacks have caused Saudi oil volumes passing through the Bab el-Mandeb strait toward Asia to drop from 3.4 million barrels a day in June to 128,000 in August, though they recovered to 700,000 in September.
The persistent fighting and lack of an exit strategy create uncertainty for international shipping and energy markets. Military experts note that while the U.S. has achieved tactical success in reopening the strait, Iran has shown a willingness to escalate through missile attacks on Arab countries hosting U.S. forces and through regional proxies. With U.S. supplies of interceptor missiles reportedly under strain, the risk of further escalation remains. The next significant milestones are the U.S. midterm elections in November, which may be influenced by the ongoing costs and fuel prices associated with the war.
