Geopolitics & money, explained calmly

Hormuz in plain English

Oil is flowing again. So why is it still so expensive?

More oil is getting out of the Gulf than in the summer, but attacks on ships, scarce diesel and LNG, and thin stockpiles are keeping prices high.

What happened

What happened (fact)

The US-Israeli war with Iran began on 28 February 2026. Its biggest economic effect runs through the Strait of Hormuz, the narrow sea passage between Iran and Oman that most Gulf oil and all of Qatar’s LNG exports pass through.

Before the war, about 20 million barrels a day (mb/d) went through it, roughly a fifth of world oil use (US Energy Information Administration, EIA, 2024 data). The International Energy Agency (IEA) counted 10.9 mb/d in September, around half the pre-war level.

Producers also go around it: routes that bypass the Strait, mainly pipelines, carried 5.6 mb/d in September. Counting both, Gulf crude exports were “over 75% of pre-war” (IEA).

But the threat is still there:

  • Ships. The Washington Institute counted 28 confirmed and reported attacks on ships near Hormuz in October (to 23 Oct), its worst month on record, Reuters reported.
  • Saudi Arabia. Yemen’s Houthis (an Iran-aligned armed group) made 20 attacks on Riyadh’s main airport from 1 to about 15 October, the Saudi-led coalition said (Arab News). Saudi Arabia’s aviation authority (GACA) said the 10 October strike killed 12 people, including one American, and injured 309. The coalition later put that day’s toll at 13, and its figures add up to 17 dead across attacks from 8 to 11 October.
  • LNG. Iranian strikes knocked out about 17% of Qatar’s capacity to export LNG (liquefied natural gas, chilled for shipping); repairs will take three to five years, QatarEnergy’s chief executive told Reuters in March.

Why it matters

What happened (fact)

Brent crude, the main global oil benchmark, has two prices. The futures price is agreed today for oil delivered later; the spot price is what a physical cargo costs for loading in the coming weeks.

That spot price was $115.22 a barrel on 20 October. December futures settled lower that day, at $108.79 (Dow Jones Market Data; Reuters); near-term cargoes costing more than later ones usually signals scarcity. Futures then rose on 22–23 October, settling at $116.72 on 23 October (Dow Jones).

Prices stay high partly because refined products, fuels such as diesel and jet fuel, are recovering more slowly: Middle East exports were 1.9 mb/d in September against 4.7 mb/d pre-war, says the IEA, which calls diesel markets “under extreme pressure”.

Global oil stocks at end-September were 509 million barrels below end-February levels (IEA), and 4.8 mb/d of production was still shut in (switched off because it can’t be safely produced or shipped) in September (EIA).

How to read this

  1. These are fuels like diesel, not crude oil. Crude has recovered faster: Gulf crude exports were over 75% of pre-war in September, counting bypass routes.
  2. Each bar is a monthly average in million barrels a day, not a single day’s count.
  3. Better flows don’t refill the tank: global oil stocks were still 509 million barrels below end-February levels.

The bigger picture

What happened (fact)

US Central Command said on 13 October that US forces and partners “clearly control” the Strait; critics cite record ship attacks and high prices. Both use real data, so ask which number: Hormuz, all Gulf exports, or only crude.

From this explainer

The New York Times, citing unnamed officials, reports US-Israeli plans for strikes on Iran after the 3 November midterms (via CNBC).

Four Lenses

How four very different thinkers read this story

Views, not facts. Each view is labelled with what it covers; counterpoints come from data or officials.

01

Luke Gromen

His view; money and markets

On 20 October he argued oil markets were rejecting official claims of US control of the Strait and of lower prices after the midterms.

02

Ray Dalio

His view; big historical cycles

In March he warned of a significant risk that losing control of Hormuz would be for the US what the 1956 Suez crisis was for Britain.

03

Robert Pape

His view; war and escalation

He sees escalation building on several fronts, with danger peaking after Election Day.

04

Multipolarity

Mainly co-host Philip Pilkington, who argues for a ‘post-liberal’ politics

He calls the “oil glut” and “Hormuz mostly open” stories an information war; high prices, he says, show real scarcity.

Counterpoint · IEA and Kpler data

The IEA says Gulf crude exports were ‘approaching pre-war levels’ in September, and Kpler put crude through Hormuz at about 80% of pre-war. The IEA says renewed attacks, record freight costs, tight diesel supply and low stocks are keeping the market strained, and Kpler data show Qatar’s LNG exports at under a quarter of pre-war (Reuters columnist Ron Bousso).

Agree / disagree

Where they agree

Gromen, Pape and Multipolarity all doubt the crisis is easing as fast as officials suggest.

Where they disagree

On the driver: markets (Gromen), great-power cycles (Dalio), escalation (Pape) or contested data (Multipolarity).

What to watch next

  • 27–28 OctoberEIA’s weekly pump prices (surveyed 26 October), the first EIA weekly figures that can reflect the 22–23 October rise in oil futures, then its Brent spot update (daily prices through about 27 October).
  • 3 Novemberthe US midterms. Trump said prices would fall ‘right after the election’, while adding it could ‘take a little bit longer’.
  • 10 NovemberEIA’s next forecast, and October US inflation figures (BLS).
  • 13 Novemberthe IEA’s next Oil Market Report, with new flow figures.

Your wallet

What this could mean for your money

Context for everyday costs, not a recommendation.

01

Gas and diesel

On 19 October, US regular gasoline averaged $4.284 a gallon and diesel $6.276 (EIA).

02

Groceries

Diesel fuels trucks and farm machinery. The IEA expects the diesel market to stay tight ‘well into 2027’ unless Middle East fuel exports recover, and says record diesel prices are already raising the cost of goods. That can feed into food prices over time. So far US grocery inflation is modest: US food prices were 2.5% higher in September than a year earlier, and grocery (‘food at home’) prices 1.8% higher (BLS consumer price index, released 14 October).

03

Mortgage rates

Oil shocks can feed into wider inflation, and inflation worries can push up the long-term interest rates that mortgages are priced from, though the link is indirect. The average 30-year fixed mortgage rate was 7.32% in the week to 22 October, down from 7.40% the week before but up from 6.19% a year earlier (Freddie Mac).

04

Savings

When prices rise faster than the interest savings earn, cash buys less over time. Consumer prices rose 3.7% in the 12 months to September (BLS), while the FDIC’s national average savings rate was 0.38% (October), an average across all banks.

Reflection Point

When official statements and market prices tell different stories, which do you watch more?

In mid-October, US Central Command said US forces and partners ‘clearly control’ the Strait, and the IEA put Gulf crude exports in September, counting bypass routes, at over 75% of pre-war levels. Yet oil prices remain high.
