Strait of Hormuz : Not just fuel

The Iran war has turned the Strait of Hormuz into the world’s most dangerous shipping lane—and the shock to our wallets is only just beginning.

From tanker traffic to triple‑digit oil

Roughly a fifth of global oil trade and about 20% of liquefied natural gas (LNG) normally squeeze through this narrow waterway.
Since late February, Iranian threats and missile and drone strikes have choked traffic, with many tankers diverting or going dark to avoid detection.
Markets reacted fast: Brent crude jumped from under 80 dollars a barrel before the attacks to above 100 dollars by mid‑March, with peaks around 107 dollars on 26 March—its highest level in nearly two year.

Asian spot LNG prices have more than doubled from about 10–11 dollars per MMBtu to over 20–25 dollars, hitting their highest levels since 2023 as 20% of global LNG supply sits effectively shut in.

Those numbers translate into higher petrol, power and transport costs that will filter through to everything from Grab rides to air tickets over the coming months.

Fertilisers: the hidden link to your grocery bill

Energy isn’t the only thing trapped at Hormuz. About a third of globally traded fertiliser components—especially nitrogen products like ammonia and urea—moves through this corridor. When shipping is “all but stopped,” producers face higher gas feedstock costs and can’t get product out, pushing fertiliser prices sharply higher.

Farmers in poorer regions respond by cutting application rates, which quietly sets up weaker harvests later in the year.
We are already seeing the first tremors: wheat prices are up about 15% and rice around 8% since the war began, while the FAO Food Price Index has climbed to a 14‑month high. If the conflict drags on into the planting season, analysts warn of another wave of food inflation and even unrest in import‑dependent regions like the Middle East and North Africa.

Plastics in almost everything

The Gulf is a powerhouse for LPG and petrochemical feedstocks such as naphtha, which are turned into plastics and synthetic fibres.
When those flows are disrupted, the cost of making packaging, textiles and everyday plastic components jumps, even if end consumers don’t see it immediately.

From food wrappers and shampoo bottles to phone casings and car interiors, these incremental increases quietly lift the price of “almost everything” on the shelf.

Qatar’s helium squeeze: chips and hospitals

Qatar normally supplies roughly a third of the world’s helium, shipped out with its LNG through Hormuz. Force‑majeure declarations and export halts have removed a big chunk of that capacity, triggering warnings of a global helium shortage. Helium is essential for cooling the extreme‑precision equipment that etches semiconductor wafers and for operating MRI scanners.

That means slower ramp‑ups for AI chips and advanced electronics, and higher costs or longer waiting times for critical medical imaging if the crunch persists.

Insurance, delays and the “second‑round” inflation

Even ships that still sail through the Gulf now pay a hefty risk premium. War‑risk insurance rates and freight costs on Hormuz‑exposed routes have jumped, and many vessels are rerouting around Africa, adding weeks and fuel costs to journeys.

These are classic “second‑round” effects: they don’t show up at the petrol pump immediately, but they raise the delivered cost of everything from grain and cooking oil to electronics and fertilisers.

Economists warn that if current conditions persist, the combined impact of energy prices, shipping costs and fertiliser shortages could push global food and energy inflation higher into late 2026, even if a ceasefire comes earlier.

Where the Iran war stands now

The crisis escalated after joint US‑Israeli strikes killed Iran’s supreme leader at the end of February, prompting Iran to declare parts of the Strait of Hormuz off‑limits and threaten attacks on “enemy‑linked” ships.

March brought a pattern of missile and drone strikes, harassment of commercial vessels and tightly controlled “safe passage” for ships from selected countries, keeping overall traffic well below normal.

Naval deployments from the US and its allies have increased, but reports of possible mine‑laying and the recent killing of a senior Iranian naval commander mean miscalculation risk remains high as of 29 March 2026.

For households, investors and policymakers, the lesson is clear: what happens in a 39‑kilometre‑wide strait is no longer just about oil. From your grocery basket and electricity bill to AI chips and hospital MRIs, the Strait of Hormuz is now a single chokepoint with many inflation shockwaves still rolling toward us.
