US-Iran War Triggers Global Oil Crisis and Inventory Collapse
The Government of the United States and Iran are locked in a conflict that has closed the Strait of Hormuz, causing global fuel inventories to plummet.
Military conflict between the Government of the United States and Iran has triggered a global energy crisis following the effective closure of the Strait of Hormuz. Hostilities escalated in early June 2026 with U.S. strikes on Qeshm Island and an Iranian oil tanker, followed by Iranian ballistic missile attacks on U.S. naval bases in Bahrain and Kuwait. While President Donald Trump indicated a willingness to maintain a ceasefire with Iran, diplomatic progress remains stalled.
The closure of the Strait of Hormuz has removed approximately 12.8 million barrels per day from the global supply. In response, the U.S. Department of Energy authorized a record 172-million-barrel release from the Strategic Petroleum Reserve and the administration invoked the Defense Production Act for California offshore drilling. Despite these measures, U.S. petroleum inventories have fallen to their lowest levels since 2004, with jet fuel hitting a 63-year low. At the Cushing, Oklahoma hub, inventories are approaching operational minimums due to record-high exports intended to stabilize global markets.
The crisis has already impacted the aviation sector, forcing Spirit Airlines to cease operations and Lufthansa to cancel 20,000 flights. In Europe, officials report no immediate jet fuel shortage but warn of a potential global recession if the waterway does not reopen. Meanwhile, Iran has institutionalized the disruption by establishing the Persian Gulf Strait Authority to charge tankers transit tolls in yuan and cryptocurrency.
