Diplomatic efforts to reopen the world’s most important oil chokepoint have stumbled, while attacks on shipping and Saudi Arabia’s oil infrastructure threaten to put millions more barrels of global supply at risk.
Diplomacy aimed at easing the crisis around the Strait of Hormuz has hit a major setback, raising fresh fears over global oil supplies as attacks across the Middle East continue to disrupt two of the world’s most important energy corridors.
A meeting between Iran and Gulf Arab states, expected to take place in Oman, has been postponed as negotiators struggle to reach a regional consensus on a proposal for managing shipping through the strategic waterway.
The development comes as oil prices have climbed above $100 a barrel, while shipping traffic through the Strait of Hormuz has fallen sharply.
For the global economy, the stakes are enormous.
The Strait normally carries roughly one-fifth of global oil supplies, making any prolonged disruption a potential threat to fuel prices, inflation, transportation and economic growth around the world.
Why the strait of hormuz matters
The Strait of Hormuz is a narrow waterway between Iran and Oman that connects the Persian Gulf with the Gulf of Oman and the Arabian Sea.
Despite its relatively small size, it is one of the world’s most strategically important energy routes.
Before the current conflict, approximately 20% of global oil supplies passed through the strait.

That means even a partial disruption can have consequences far beyond the Middle East.
Fewer ships crossing the waterway means less oil reaching international markets.
Reduced supply can push prices higher.
Higher crude prices can then translate into more expensive petrol, diesel, aviation fuel, transportation and manufactured goods.
And eventually, consumers around the world can feel the impact.
Diplomacy hits a wall
There had been hopes that Oman could help broker an arrangement between Iran and Gulf states to protect shipping through the strait.
But those hopes weakened after Oman’s Foreign Minister, Sayyid Badr Albusaidi, announced that the scheduled regional meeting had been postponed in the interests of reaching consensus.
Iran also confirmed the postponement, saying it was made jointly with Oman after requests from some regional countries.
The delay comes at a particularly sensitive moment.
Iranian Foreign Minister Abbas Araqchi has reportedly said that even if Tehran reaches an agreement with Oman, Iran will not reopen the Strait of Hormuz until the United States meets its demands.
That means the diplomatic route to restoring normal shipping remains uncertain.
Shipping through hormuz falls
The uncertainty is already showing up in shipping data.
Preliminary ship-tracking information indicates that commodity vessel traffic through the Strait of Hormuz fell to single-digit transits per day over the weekend.
That is significantly below the recent 10-day average of about 14 vessels per day.
The figures may not capture vessels that have switched off their tracking systems to avoid detection, but the broader trend points to a severely disrupted shipping corridor.
The latest incident involved a vessel that was struck by a projectile while travelling through the strait, according to the British maritime security agency UKMTO.
A fire broke out and the crew was evacuated.
Iran also reported that an Iranian commercial vessel was struck off its coast, killing one person and injuring four crew members.
Saudi pipeline adds to the pressure
The crisis is not confined to the Strait of Hormuz.
Saudi Arabia has shut down its 1,200-kilometre East-West pipeline, which provides an alternative route for moving oil to the Red Sea without using the Strait of Hormuz.
That development has removed an important safety valve for Gulf oil exports.
Saudi oil buyers and traders told Reuters that the kingdom currently has enough oil stored at its Red Sea port of Yanbu to maintain exports for only about five to seven days if the pipeline remains offline.
If the pipeline remains shut for longer, as much as 4% of global oil supply could be placed at additional risk.
That would come on top of the millions of barrels already affected by the disruption to shipping through Hormuz.
Oil prices are already responding
Global oil markets have reacted sharply to the growing supply concerns.
Crude prices jumped more than 3% on Monday, after attacks on Saudi Arabia, the pipeline disruption and further incidents involving shipping in the Gulf.
Oil had already climbed above $100 a barrel last week for the first time since July.
The pressure is also being felt downstream.
U.S. retail diesel prices rose above $6.20 per gallon, setting another record.
The longer the disruption continues, the greater the potential impact on global energy markets.
Why this matters to ordinary consumers
The Strait of Hormuz may be thousands of kilometres away from most consumers, but an extended disruption could eventually reach household budgets.
Higher crude prices can raise the cost of:
- Petrol and diesel
- Aviation fuel
- Shipping and freight
- Food transportation
- Manufacturing
- Electricity generation in some markets
- Consumer goods
For countries that import petroleum products, the consequences can be particularly severe.
Higher international crude prices can increase import costs, put pressure on currencies and worsen inflation.
For businesses, more expensive energy means higher operating costs.
For households, it can mean higher transportation and food bills.
A crisis in a narrow waterway can therefore become a cost-of-living crisis thousands of kilometres away.
The other chokepoint: bab el-mandeb
At the same time, the Bab El-Mandeb Strait — the strategic gateway connecting the Red Sea to the Gulf of Aden — is also facing renewed instability.
Iran-aligned Houthi rebels in Yemen have continued attacks in the region while advancing along parts of the Red Sea coast.
The Houthis have also claimed attacks against Saudi military targets.
Their activity creates another threat to international shipping.
Together, Hormuz and Bab El-Mandeb represent two critical gateways for global energy and commercial trade.
Disruption at both could significantly increase shipping costs and pressure already-fragile supply chains.
Saudi arabia seeks help
The growing Houthi threat has also put Saudi Arabia in a difficult position.
Three sources told Reuters that Saudi Crown Prince Mohammed bin Salman spoke with U.S. President Donald Trump on Thursday and requested military assistance against the Houthis.
For now, Washington reportedly offered intelligence support rather than direct military involvement.
The dilemma for the United States is complicated.
Washington wants to protect its Saudi ally and international shipping routes, but deeper military involvement risks opening another front in an already expanding regional conflict.
Trump says he wants a deal
President Trump has maintained that he expects the Iran conflict to end this year.
During a weekend trip to Ireland, he reiterated that position and suggested that the war could potentially conclude after the U.S. midterm elections in November.
Trump has also said Iran has been repeatedly seeking talks.
But Tehran’s position remains firm: the Strait of Hormuz will not fully reopen until the United States meets its demands.
That leaves diplomacy facing a difficult test.
What happens if hormuz stays closed?
The biggest concern is duration.
A short disruption could create a temporary shock in oil markets.
A prolonged closure could be much more damaging.
The longer ships remain unable or unwilling to pass through Hormuz, the greater the pressure on available global oil inventories.
If alternative supply routes cannot compensate, prices could rise further.
Higher energy costs could then feed into inflation, transportation and manufacturing — creating a ripple effect across the global economy.
And if the Saudi pipeline remains offline at the same time, the pressure could become even greater.
