Enforcement remains intense and diplomacy stalled, so an official U.S. announcement ending the Iranian naval blockade by October 31 is a meaningful underdog.

The visible evidence leans firmly against a timely lifting announcement: U.S. forces continue redirecting vessels, Washington is sustaining military and economic pressure, and diplomacy remains stalled. The outcome remains live because Oman is pursuing a regional shipping framework and Washington has already shown it can reverse blockade policy quickly through official channels. Continued enforcement beyond October 31 is the most likely result.

Points to NO

Active U.S. enforcement shows the blockade remains fully operational rather than winding down.
On September 12, U.S. forces were still enforcing the blockade, and CENTCOM reported redirecting 100 commercial vessels during the preceding 60 days.
Trump has pointed to a conflict endpoint after the announcement deadline.
On September 10, Trump said the Iran war would end immediately after the November midterm election, which falls after October 31.
Current negotiations have not produced an imminent settlement of the shipping dispute.
As of September 12, negotiations were continuing, but officials did not expect an immediate agreement resolving commercial-shipping security concerns.

Points to YES

The Oman process provides an active diplomatic route toward restoring maritime traffic.
On September 12, Iran's president said Iran and Oman would sign a shared-route agreement in Muscat on September 14 with Arab foreign ministers present.
Washington has previously ended comparable enforcement abruptly through an official military announcement.
On June 18, CENTCOM announced that the blockade on maritime traffic entering and exiting Iranian ports had been lifted and all enforcement efforts had ceased.
