The Risk the War in Iran Poses to the Global Economy

TL;DR

Iran's closure of the Strait of Hormuz threatens 20% of global oil supply, triggering inflation, trade disruption, and economic shockwaves far beyond the region.

Key Points

• 1.Strait of Hormuz closure: Iran's Revolutionary Guard closed the strait after US-Israel strikes, stranding hundreds of ships and halting ~31% of seaborne crude daily. Oil prices surged — WTI hit ~$90/barrel (up 30%), Brent rose 25% to $91.
• 2.Alternative routes exist but fall short: Saudi Arabia's pipeline can redirect ~5M barrels/day and UAE has direct Gulf of Oman access, but Ryside Energy still estimates a supply drop of 8–10 million barrels/day (~10% of global supply).
• 3.Beyond oil — natural gas and food: European natural gas futures jumped 60%; urea (a key fertilizer) prices rose 25% as ~1/3 of global supply also flows through the strait, threatening food prices worldwide.
• 4.Regional economic damage: Gulf nations with nationalized oil face direct revenue loss; tourism-dependent UAE (14% of GDP) faces capital flight; Saudi Aramco was targeted by drone strikes, though infrastructure was undamaged.
• 5.US economic risks: Higher inflation from oil and freight costs may force the Fed to hike rates; Treasury yields have risen (unusual for wartime); war spending could worsen the deficit, especially after tariff revenue losses from a recent Supreme Court ruling.
• 6.Long-term scenario: The Keel Institute estimates a sustained war could cost Iran $1 trillion in capital and shrink its economy 30% over 5 years, with other nations losing a cumulative $1 trillion+ in GDP.
