U.S. Navy Blockade of Iran Begins as Peace Talks Collapse, Oil Surges Past $104
The morning briefing on the U.S. naval blockade of Iranian ports going live today, the collapse of Islamabad peace talks after 21 hours, and oil surging past $104 a barrel.
The United States Navy began blockading all maritime traffic entering and exiting Iranian ports at 10 AM ET this morning, hours after the most significant U.S.-Iran diplomatic talks since 1979 collapsed in Islamabad without a deal, sending oil prices surging past $104 a barrel and stock futures tumbling. CENTCOM confirmed the operation begins under a presidential proclamation, covering all vessels of all nations — including Chinese and Indian ships — calling at Iranian ports on the Persian Gulf and Gulf of Oman. CENTCOM did specify that non-Iranian shipping transiting the Strait of Hormuz to other ports will not be impeded, a narrower scope than Trump’s Truth Social post suggesting the entire strait would be blockaded.
The Islamabad talks — led by Vice President JD Vance, Steve Witkoff, and Jared Kushner for the U.S., and Parliament Speaker Mohammad Baqer Ghalibaf and Foreign Minister Abbas Araghchi for Iran — ran 21 hours across Saturday and Sunday before collapsing on three unresolved issues: Iran’s refusal to end uranium enrichment, continued funding of proxy groups including Hezbollah and Hamas, and the Strait of Hormuz toll question. Vance called the outcome “bad news for Iran much more than it’s bad news for the United States.” Iran’s FM Araghchi said they were “inches away from an MoU” and accused the U.S. of moving the goalposts. The two-week ceasefire, set to expire April 22, technically remains in place. The War Powers clock expires April 28. Congress has not been briefed.

Quick Hits
- Iran Calls Blockade "Illegal" and "Piracy" — Iran's armed forces described CENTCOM's port blockade as "illegal" and an act of piracy, saying it violates international law governing freedom of navigation. Iran's parliament speaker warned Americans to "enjoy" current gas prices, implying worse is coming. [Source]
- War Powers Clock: 15 Days Left, No Authorization, No Briefing — The 60-day War Powers Resolution clock expires April 28 — 15 days from today. Congress has not authorized the war, has not been briefed on the ceasefire or blockade terms, and is not represented in any active negotiation. The naval blockade is a new military operation executed without any congressional notification.
- Trump Admits Oil Prices Could Stay High Through Midterms — Asked about energy costs Sunday, Trump acknowledged that U.S. oil and gas prices may remain elevated through November's midterm elections — the first time he has publicly conceded the domestic political cost of the war's energy disruption. [Source]
- U.S. Considering Resuming "Limited" Strikes on Iran — Iran The Wall Street Journal reported Sunday that Trump is weighing resuming limited strikes against Iranian infrastructure alongside the blockade, citing administration sources. No formal announcement has been made. [Source]
- Ceasefire Expires April 22 — No Extension Mechanism in Place — The two-week ceasefire formally expires April 22. With no next round of talks scheduled, no mediator framework for an extension, and a new naval blockade beginning today, there is currently no diplomatic mechanism to prevent the war from resuming in full when the clock runs out.
What to Watch For
10:00 AM ET: CENTCOM naval blockade of Iranian ports goes live. Watch for Iran’s military response, first ship interdictions, and whether China or India formally protest the blockade of their shipping.
All day: Whether Iran retaliates against U.S. naval assets or resumes missile and drone attacks on Gulf states in response to the blockade.
All day: Oil price movement. WTI above $104 this morning — any incident in the strait could push it significantly higher. JPMorgan has warned of $150/barrel if diplomacy fully collapses.
Tuesday: Lebanese and Israeli ambassadors meet at the State Department for the first direct talks on a Lebanon ceasefire. Lebanon’s fate remains the unresolved thread that has strained every agreement.
War Powers: 15 days until April 28. The blockade is a new, unilateral military escalation. No AUMF has been introduced. No hearing scheduled.
By The Numbers
Price per barrel of WTI crude oil this morning, up 8% overnight on the blockade announcement. Brent topped $103. Oil has risen roughly 60% since Operation Epic Fury began February 28.
National average price for a gallon of regular gasoline, up 25-30% since the war began. Trump acknowledged Sunday the price may not drop before November's midterms.
Hours the Islamabad talks ran before collapsing Sunday without a deal, a Memorandum of Understanding, or a scheduled follow-up session.
Days until the War Powers Resolution 60-day clock expires April 28. The naval blockade represents a new, unauthorized military escalation.
Kilograms of highly enriched uranium the U.S. is demanding Iran surrender — the single issue that killed the Islamabad talks. Iran has refused to give up enrichment under any terms presented.
Quote of the Day
"The bad news is that we have not reached an agreement. And I think that's bad news for Iran much more than it's bad news for the United States. They have chosen not to accept our terms." — Vice President JD Vance, press conference in Islamabad, April 12, 2026.

Bottom Line
The Iran war entered a new and more dangerous phase this morning. The Islamabad talks produced 21 hours of the most direct U.S.-Iran engagement since 1979 and collapsed on a gap that six weeks of bombing did not close — Iran's nuclear program. The naval blockade now going live is a major military escalation executed without congressional authorization, 15 days before the War Powers clock expires. Oil is back above $104. The ceasefire expires April 22 with no renewal mechanism and no follow-up talks scheduled. The Six — Maj. O'Brien, Capt. Khork, CWO3 Marzan, Sgt. 1st Class Amor, Sgt. 1st Class Tietjens, Sgt. Coady — died in a war that Congress still has not voted to authorize. That gap has not closed either.
