Episode notes
How War Raises Prices Beyond Gasoline
- War-driven oil price shocks ripple through fertilizers, plastics, shipping, and airline fuel, raising costs beyond gasoline.
- Anna Helhoski explains diesel, jet fuel, petrochemicals, and strait-of-Hormuz disruptions cause staged price increases over 6–12 months.
Oil Spike From Strait Disruptions Drove Recent Gas Hike
- Brent crude spiked from about $80 to over $100 per barrel after the Iran conflict, pushing U.S. pump prices up roughly 43%.
- The Strait of Hormuz closure and pipeline attacks made global supply volatile, briefly lowering prices only after a fragile ceasefire.
Fertilizer And Plastics Face Delayed Price Shocks
- Fertilizer and plastics are especially exposed because large shares of seaborne exports and feedstocks transit the strait.
- Anna notes about a third of seaborne fertilizer and ~85% of Middle Eastern polyethylene exports move through that route.
