The shipping lanes around the Persian Gulf are open again. Just a day after President Donald Trump and Iranian President Masoud Pezeshkian signed the Islamabad Memorandum of Understanding, US Central Command confirmed its warships are standing down. The 110-day naval blockade on Iranian ports is officially over.
It is a massive development. Oil tankers are already moving. Overnight, more than 12.5 million barrels of crude pushed through the Strait of Hormuz. That is the highest volume since this brutal conflict flared up. If you have noticed gas prices dipping below four dollars a gallon this week, this deal is the exact reason why.

But do not confuse a temporary stand-down with lasting peace. This agreement opens a high-stakes 60-day window of frantic diplomacy. Washington and Tehran are trying to untangle a catastrophic war, but the structural triggers that started the fighting are still very much alive.
The Cost of the 110-Day Squeeze
To understand why CENTCOM lifting this blockade is such a big deal, we have to look at what the last few months looked like. The US military locked down Iran's coasts on April 13. This happened right after Iran shut down the Strait of Hormuz in March. They were retaliating for the joint US-Israeli airstrikes that killed Supreme Leader Ali Khamenei on February 28. Similar reporting on this matter has been provided by The Guardian.
The economic fallout was immediate. The Strait of Hormuz handles roughly 20 percent of the world's petroleum and liquefied natural gas. When the US blocked Iranian ports and Iran choked off the strait, global energy markets went into absolute chaos.
The blockade was aggressive. CENTCOM used everything from F-35 fighter jets and MQ-9 Reaper drones to AH-64 Apache helicopters to enforce the perimeter. According to military data released earlier this month, American warships turned away 134 vessels and disabled seven others that tried to run the blockade. It was a chokehold designed to break Iran's financial spine. It worked well enough to force Tehran to the negotiating table, but it almost took the global economy down with it.
Inside the Islamabad Deal
The deal that ended the blockade did not happen overnight. Pakistan Prime Minister Shehbaz Sharif acted as the primary mediator, bringing both sides to a digital signing ceremony. What they produced is a 14-point framework known as the Islamabad MoU.
Here is what the initial phase actually guarantees. You get an immediate cessation of the naval blockade. Iran gets temporary US sanctions waivers so it can sell its oil again. In return, Tehran has to pause its uranium enrichment and let international inspectors verify and destroy its highly enriched stockpiles.
Vice President JD Vance made the administration's stance clear during a White House briefing. He openly admitted that Washington is not relying on trust. The administration is watching actions, not words. The US Navy is keeping its warships in the Persian Gulf and the Gulf of Oman. They are not blocking traffic anymore, but they are absolutely monitoring every single ship. Trump has already threatened to resume heavy military strikes if a final, permanent treaty is not hammered out before the 60-day clock runs out in Switzerland.
The Complications Most People Are Ignoring
It looks like a win on paper. Tankers are moving, prices are dropping, and the immediate threat of a wider global depression has receded. But if you look closer, the friction points are glaring.
First, look at the money. Rumors are flying about Iran getting access to 300 billion dollars in frozen assets or reconstruction funds. Vance flatly denied that the US would provide a single penny. Any outside foreign investment from wealthy Gulf Arab states like the UAE will require strict US sign-offs. Washington wants to use that economic access as a leash. If Iran behaves, the US allows the investment. If they do not, the economic trap snaps shut again.
Then there is the issue of transit fees. Mohammad Bagher Ghalibaf, Iran's chief negotiator, went on state television to declare that the Strait of Hormuz will never return to prewar conditions. Iran is honoring a 60-day toll-free window right now. Once that expires, they plan to charge commercial vessels transit fees to pass through the waterway. The White House has repeatedly stated that international waterways must remain free of tolls. This issue alone could tank the upcoming Swiss negotiations.
The Wildcard in Southern Lebanon
You cannot look at this agreement in a vacuum. Geopolitics do not work that way. While Washington and Tehran are pausing their fight, the regional proxy dynamics remain explosive.
Iran's foreign ministry issued a blunt warning right after the MoU was signed. They stated that Israel's ongoing military presence in southern Lebanon could completely void the agreement. Israel has actually expanded its operational zones in the south, completely ignoring calls to withdraw. Hezbollah leaders are claiming the MoU is a victory that proves Israel can be pushed out, while Israeli Prime Minister Benjamin Netanyahu shows zero intention of dismantling his buffer zone.
If Israel and Hezbollah escalate further north of the Litani River, Iran could easily pull the plug on the framework. If that happens, the US naval blockade goes back up within hours.
Track the shipping data over the next two weeks. Watch the progress of the nuclear inspectors entering Iranian facilities. If those inspections stall, or if Iran tries to enforce early maritime restrictions in the strait, the energy market will panic again. The blockade has lifted, but the ships are sailing through incredibly shallow diplomatic waters.
