The significance of closing the southern Omani route goes beyond the specific ships that use it. The U.S. Navy's dark transit escort operations — helping oil tankers transit with transponders turned off — have used that Omani corridor as the operational pathway. If that route closes under a finalized Iran-Oman agreement, the dark transit workaround that has been moving a small but meaningful volume of oil also closes. Iran would then control both the northern corridor through its territorial waters and the southern corridor that would be shut under the deal — giving Tehran the comprehensive Hormuz management role it has been seeking since the conflict began. |
For the United States, this is the specific scenario it has repeatedly said it will not accept. Bessent, Rubio, and Trump have all explicitly stated the U.S. will not allow Iran to establish a toll-collection framework or transit management role over an international shipping lane. A deal that closes the southern Omani route and establishes Iran-managed corridors as the only passage options is, by the U.S. definition, precisely that framework — regardless of what it is called in the Oman-Iran joint statement. |
