GEOPOLITICS: THE STRAIT OF HORMUZ

Let’s call it the world’s most expensive bottleneck: a 21-mile-wide sip of water between Iran and Oman that quietly decides what you pay at the pump, what lights up Tokyo, and whether a container of urea makes it to a farm in Iowa.

GEOPOLITICS 

THE STRAIT OF HORMUZ

The Strait of Hormuz: a sliver of sea, an outsized shadow

Picture the map. The Persian Gulf is a bathtub of oil; the Strait of Hormuz is the drain. At its narrowest point it’s just 33–52 km wide (21–33 miles), with shipping lanes only 2 miles across each way. Yet in 2025 it carried roughly 20 million barrels of oil a day—about one in every five barrels the world consumes, and roughly a third of all seaborne crude trade. Add LNG, and you’ve got ∼20% of global liquefied natural gas squeezing through the same channel (Qatar alone exported >112 bcm via the strait in 2025). 

Why it matters beyond oil:

• Asian lifeline. China moves ∼40% of its oil imports through Hormuz (≈4.9 mb/d) and ∼30% of its LNG from Qatar/UAE. Japan and South Korea are similarly exposed; India leans on it for the bulk of its crude.  • Food security ripple. Around one-third of globally traded fertiliser—including nearly half of urea and sulphur exports—transits the strait. Block the water, and you eventually pinch farms, not just fuel tanks.  • No Plan B. The much-talked-about bypass pipelines (Saudi East-West, UAE’s ADCOP) can only offset a fraction of the flow; combined spare capacity is minimal. If the strait stops, the world’s spare production capacity—concentrated in the same Gulf states—gets stranded too.  

2026: the year the chokepoint snapped

On 28 February 2026 the strait effectively closed to commercial traffic amid the US-Israel-Iran confrontation. The shock was immediate: analyses put stranded crude at ∼14.8 mb/d with no viable export route. Oil spiked toward 100/bbl, U.S. gasoline touched ~3.59/gal, and insurers and lines (Maersk, MSC, Hapag-Lloyd, CMA CGM, COSCO) suspended or curtailed transits. Dry-bulk passages plunged ∼91% in March, with ∼280 bulk carriers reportedly stuck inside the Gulf. 

The political scramble is now a daily headline:

• The U.S. has pressed China, the UK, France, Japan, South Korea and others to send warships to help secure the lane; President Trump publicly urged a multinational naval presence while vowing U.S. strikes on Iranian boats.  • The EU’s foreign policy chief said member states are discussing measures to keep Hormuz open.  • France and Italy have explored talks with Iran to negotiate safe passage, even as Iran’s foreign minister insists the strait is “open—except to enemies”. 

Why it’s hard to “just keep it open”

Geography is brutal. Iran sits on the north shore; Oman/UAE on the south. The lanes themselves are international waters under UNCLOS, but the margins are tight and contested. A single drone, mine, or missile in that 2-mile-wide channel can freeze traffic. And because the Gulf holds >90% of the world’s spare production capacity, a closure removes not just today’s barrels but the emergency buffer the market relies on. 

Bottom line for the rest of us

When Hormuz coughs, the global economy catches a cold—fast. A short disruption is an oil price story; a prolonged one becomes inflation, shipping reroutes around Africa (adding 1–2 weeks per voyage), and a squeeze on gas and fertiliser that hits power bills and food chains. That’s why, for a strip of water you could cross in a short ferry ride, the whole world keeps an eye on it. 
