US-Iran Peace Talks Teeter as Trump’s Blockade and Ship Seizure Spark Global Oil Surge
ISLAMABAD — The prospect of a diplomatic breakthrough is fading as the second round of US-Iran peace talks hangs in the balance.
Iran announced Monday that it has yet to decide if its officials will join U.S. envoys in Pakistan, following a volatile weekend that saw Washington seize an Iranian ship.
Esmail Baghaei, the spokesperson for Iran’s Foreign Ministry, confirmed there are currently “no plans” for the next phase of negotiations. He emphasized that Tehran will prioritize its national interests as it evaluates its next move.
While Iranian President Masoud Pezeshkian expressed a desire for diplomacy Monday morning, his tone remained cautious. He noted that while every rational path to reduce tension should be used, “distrust of the enemy and vigilance” remain absolute necessities, he stated via state media.
The uncertainty casts a shadow over the scheduled meetings in Islamabad. Despite Iran’s hesitation, the U.S. delegation—headed by Vice President J.D. Vance—is proceeding with the trip. Vance is expected to arrive late Monday with special envoy Steve Witkoff and Jared Kushner.
The situation is further complicated by a fragile two-week cease-fire set to expire early Wednesday. The truce is now under extreme pressure after the U.S. seizure of an Iranian cargo ship.
The vessel was allegedly attempting to skirt President Donald Trump’s blockade in the Strait of Hormuz, a maritime chokepoint through which roughly 20% of the world’s oil flows.
President Trump claimed the U.S. Navy intercepted the ship in the Gulf of Oman by “blowing a hole in the engine room,” effectively taking custody of the vessel.
Adding to the tension, U.S. Central Command (CENTCOM) reported Monday that 27 vessels have been ordered to turn back or return to Iranian ports since the blockade began on April 13, according to CENTCOM records.

A Cycle of Mutual Accusations and Regional Spillover
Tehran has characterized the U.S. blockade and the subsequent ship seizure as “maritime piracy,” according to reports from Iran’s joint military command.
First Vice President Mohammad Reza Aref warned Sunday that Iran will maintain economic pressure on global naval navigation so long as the blockade persists.
“The choice is clear: Either a free oil market for all or the risk of significant costs for everyone,” Aref stated.
Foreign Ministry spokesperson Baghaei labeled the blockade a criminal violation of the Pakistani-mediated cease-fire. He further claimed that violations are also occurring in Lebanon.
This comes as the Israeli military confirmed it is maintaining positions in southern Lebanon and issuing new evacuation warnings.
The broader regional stability rests on a 10-day cease-fire between Israel and Lebanon brokered by Trump. Despite the friction, Reuters reports that this specific agreement is largely holding.
Conversely, President Trump has accused Iran of firing bullets in the Strait of Hormuz over the weekend, violating the U.S.-Iran truce.
The U.S. President renewed his threat to strike Iranian infrastructure if a deal is not reached. “The United States is going to knock out every single power plant, and every single bridge, in Iran,” Trump warned.
Baghaei dismissed these claims, asserting that Iran does not accept ultimatums when securing its national interests.
Global Economic Shockwaves: Oil Prices Spike
The instability in the Gulf has sent shockwaves through energy markets. Early Monday, Brent crude climbed to approximately $95 per barrel, a sharp 5% increase from Friday’s close.
This surge follows a pattern of instability that began with U.S.-Israeli strikes on Iran on Feb. 28, leading to restrictive maritime access in the Strait.
European leaders are now prioritizing the total reopening of the waterway. British Prime Minister Keir Starmer and French President Emmanuel Macron recently led a summit in Paris to support the freedom of navigation.
The two leaders announced a multinational defensive mission to protect merchant ships and clear mines, though it will only be deployed following a sustainable cease-fire.
Meanwhile, Chinese President Xi Jinping called for an immediate, comprehensive cease-fire to restore normal trade passage.
Can diplomacy prevail when trust has been completely eroded? Or is the world watching the preamble to a much larger conflict?
Will the U.S. strategy of “maximum pressure” via blockade eventually force Tehran to the table, or will it only accelerate a global energy crisis?
The Strategic Weight of the Strait of Hormuz
To understand the gravity of the current impasse, one must look at the geography of the Strait of Hormuz. This narrow waterway connects the Persian Gulf with the Gulf of Oman and the Arabian Sea.
For the global economy, it is a singular point of failure. Because there are few viable overland alternatives for transporting oil from Saudi Arabia, Iraq, and the UAE, the Strait is the primary artery for global energy security.
Historically, Iran has used the threat of closing the Strait as a strategic lever against international sanctions. According to the Council on Foreign Relations, the ability to disrupt this flow gives Tehran disproportionate influence over global Brent crude pricing.
Furthermore, the volatility in oil prices is closely monitored by the International Energy Agency (IEA), as spikes often lead to inflationary pressures in developed economies, affecting everything from transport costs to consumer goods.
