Key Takeaways
- U.S. Central Command (CENTCOM) officially rejected Iranian state media claims that Tehran has restricted shipping to specific routes in the Strait of Hormuz, asserting that Iran does not control the waterway.
- Maritime traffic has ground to a near-standstill as of July 9, 2026, following two days of intensive tit-for-tat military strikes between the U.S. and Iran, leaving approximately 6,000 seafarers stranded on hundreds of vessels.
- Oil prices spiked approximately 7% this week, with WTI crude rising toward $75.30 per barrel after President Donald Trump declared the June 18 ceasefire memorandum "over" following Iranian attacks on commercial tankers.
- U.S. forces have conducted strikes on nearly 100 targets within Iran over the last 48 hours, including air defense systems, coastal radar sites, and more than 60 IRGC small boats to degrade Tehran's ability to disrupt international commerce.
Escalation in the Strait of Hormuz
U.S. Central Command (CENTCOM) issued a sharp rebuttal to Iranian media reports on Thursday, stating that claims of restricted passage through the Strait of Hormuz are "categorically false." The command emphasized that the waterway remains under international authority and that Tehran does not possess the legal or military control to dictate shipping routes. This statement follows an attempt by Iran’s newly formed Persian Gulf Strait Authority to mandate that all commercial vessels use specific, Tehran-approved routes or face "strict prohibition."
The dispute centers on conflicting interpretations of the June 18 Memorandum of Understanding (MOU). While Iran argues the agreement grants it the right to manage "arrangements for safe passage," the United States maintains that the strait must remain an open international trade corridor. In response to recent Iranian aggression, CENTCOM reported that its forces have supported the safe movement of more than 800 commercial ships carrying roughly 380 million barrels of crude oil since early May.
Military and Economic Impact
The security situation has deteriorated rapidly since July 7, when the U.S. launched a massive wave of airstrikes hitting over 80 targets in southern Iran. These strikes were a direct response to Iranian drone and projectile attacks on three commercial tankers. On July 8, a second wave of strikes targeted an additional 90 military sites, including command-and-control networks and anti-ship missile batteries. In retaliation, the Islamic Revolutionary Guard Corps (IRGC) launched missiles and drones at U.S. military facilities in Bahrain, Kuwait, and Jordan.
The renewed hostilities have effectively frozen one of the world's most vital energy chokepoints. Ship-tracking data from Bloomberg (BLP) shows that most observable traffic is now occurring only along the northern, Iran-approved routes, while the U.S.-supported Omani corridor remains largely empty. Many vessel operators have reportedly turned off their transponders to avoid detection, a practice that hasn't been seen at this scale since the height of the February 2026 conflict.
Market Reactions and Outlook
Global energy markets are reacting with high volatility to the collapse of the fragile truce. The U.S. Treasury Department has revoked oil sanctions waivers previously granted to Iran, further tightening global supply. Analysts at Argus Media noted that the resumption of direct military confrontation has reversed the downward trend in oil prices seen throughout June.
While President Trump has suggested that talks could potentially continue, he warned of "much worse" consequences if Iran continues to target commercial shipping. The United Nations International Maritime Organization (IMO) has advised all transit through the Strait of Hormuz be avoided until safety conditions are restored. As of Thursday evening, the region remains on high alert, with the risk of a broader regional conflict reaching its highest point in months.
