The Diary of a CEOSteve Keen: Why Hormuz risks famine, not just an oil shock
How the Strait of Hormuz carries fertilizer the world depends on. Why a closure cascades into chip shortages, energy GDP shocks, and nuclear-escalation paths.
At a glance
WHAT IT’S REALLY ABOUT
Strait of Hormuz risks trigger energy, chip, and food crises worldwide
- Keen claims the Strait of Hormuz is the true global choke point because it routes not only oil but also major shares of fertilizer inputs and helium, making supply disruption a direct threat to food and semiconductor production.
- He predicts fertilizer shortages could translate into sharp falls in global food output within months, potentially creating a worldwide famine rather than localized crises.
- He outlines five war-end scenarios ranging from catastrophic nuclear escalation (including Israel’s “Samson Doctrine”) to Iran neutralizing Israel’s nuclear capability, which he presents as the most likely and safest outcome.
- The discussion broadens into macroeconomics: energy availability tightly tracks GDP, so sustained energy supply losses could cause a sizable global output contraction and worsen cost-of-living pressures and inequality.
- Keen warns of a separate near-term financial downturn driven by an AI investment boom-bust cycle and argues policies like universal basic income may become necessary as AI/robots erode employment.
IDEAS WORTH REMEMBERING
5 ideasThe Hormuz chokepoint is framed as a food-and-chips risk, not just an oil story.
Keen argues 20–30% of fertilizer-related flows and ~30% of helium supply are tied to the Gulf routing, so disruption threatens crop yields and semiconductor output alongside fuel prices.
Fertilizer constraints are presented as a fast-moving famine trigger.
He claims major import-dependent countries could exhaust fertilizer supplies within months, implying a rapid hit to planting, yields, and global food availability rather than a slow price-only effect.
Energy supply shocks propagate directly into global GDP contraction.
Using an energy vs. gross world product relationship, Keen contends a 5–10% energy drop could produce a comparable fall in world output, amplifying inflation and job stress.
Critical industrial inputs (helium) are treated as non-substitutable bottlenecks.
Because helium is difficult to stockpile and has no chemical substitute for certain chipmaking steps, Keen suggests a supply interruption could halt parts of semiconductor production, compounding tech and logistics disruptions.
The most catastrophic tail risk discussed is nuclear escalation via ‘Samson Doctrine.’
He argues that if Israel perceives existential defeat, it could consider extreme escalation; he assigns a non-trivial probability to nuclear-use scenarios and stresses disabling nuclear options as decisive for survival.
