The Strait of Hormuz has always been a fuse. Now Iran’s Islamic Revolutionary Guard Corps has lit a match. On Thursday, the IRGC warned against any attempt to bypass the strategic waterway, calling a proposed alternative route a “hostile act” that could derail ongoing negotiations.
The warning came just days after reports emerged that several Gulf states and international shipping firms were exploring a new passage to reduce reliance on Hormuz. The strait, a narrow chokepoint between Oman and Iran, handles about 20% of the world’s oil traffic. For decades, Iran has used its control over Hormuz as leverage — a geopolitical crowbar that few dare to challenge.
The anatomy of a threat
IRGC commander Hossein Salami didn’t mince words: “Any vessel using an illegal route under the pretext of avoiding Hormuz will be considered a target.” That’s not diplomatic language. That’s a red line drawn in saltwater.
The Corps has a history of backing up such rhetoric with action. In 2019, Iran seized tankers, shot down a US drone, and was widely blamed for attacks on Saudi oil facilities. The IRGC’s naval wing operates fast boats, mines, and anti-ship missiles. They don’t bluff.
So when they say a new route is unacceptable, the shipping industry listens. Lloyds of London has already raised insurance premiums for vessels in the region. Oil futures wobbled. The market knows that a single IRGC speedboat can turn a routine transit into an international incident.
The alternative route: a workaround that works?
The proposed bypass is not new. It involves a pipeline from the UAE to Fujairah on the Gulf of Oman, plus a Saudi-led plan to build a canal across the Arabian Peninsula. Technically feasible. Politically explosive.
Proponents argue it would reduce Iran’s stranglehold, lower shipping costs, and provide a buffer against military escalation. But experts say the economics are shaky. The pipeline capacity is limited. The canal would take years and billions. And neither option eliminates the need for Hormuz entirely — they just trim its dominance.
More importantly, any alternative route would require the cooperation of Iran’s rivals: Saudi Arabia, the UAE, and Israel. That alone makes it a provocation in Tehran’s eyes.

Negotiations in the balance
The warning comes at a delicate time. Iran and the Gulf states are engaged in talks under Iraqi and Omani mediation, aiming for a comprehensive agreement on maritime security, trade, and diplomatic relations. The Hormuz issue is the elephant in the room — or maybe the battleship.
Iran wants transit fees indexed to oil prices and a guarantee that its own ships won’t be harassed. The Gulf states want unimpeded passage and a mechanism to resolve disputes without Iranian gunboat diplomacy.
The IRGC’s statement suggests that even discussing alternatives is a deal-breaker. That complicates matters for negotiators who need to show their domestic audiences that they’re not surrendering to Iranian pressure.
“The IRGC is signaling that the talks have limits,” said Sanam Vakil, director of the Middle East programme at Chatham House. “They’re willing to talk, but not about the strait itself. That’s the one card they won’t fold.”
Oil market jitters
Oil prices rose 2% on the news. Brent crude flirted with $88 a barrel. Traders hate uncertainty, and Hormuz is uncertainty squared.
If the IRGC follows through on its threat, the impact could be immediate. Iran has already been accused of targeting tankers with limpet mines in the past. A single attack on a vessel testing the alternative route could send insurance costs through the roof and push oil above $100.
But there’s also a chance this is posturing. The IRGC knows that a full blockade would invite US naval retaliation — something Iran wants to avoid as it struggles with sanctions and internal unrest. Still, the risk is real.
The US Fifth Fleet, based in Bahrain, has its hands full. Washington has warned Iran against “reckless actions” but has not committed to protecting any alternative route. The message: you’re on your own.
What’s next?
Talks will continue, but the shadow of the IRGC looms large. The Gulf states must decide whether to push ahead with the alternative route and risk confrontation, or back down and accept Iran’s terms. Neither option is good.
The smarter move might be to keep the alternative on the table as leverage, while negotiating a better deal on Hormuz transit fees. But the IRGC’s ultimatum makes even that seem like a threat.
This is not just about shipping; it’s about power. The Strait of Hormuz is Iran’s last great lever of influence in a region where its proxies are under pressure and its economy is in tatters. Give it up, and the regime loses its teeth. That’s why the IRGC will fight for it — with words, with mines, or with blood.
Nobody said diplomacy was easy. But when the IRGC talks, the world listens. And right now, it’s hearing the sound of a trigger being cocked.
