Key Differences
Oil Supply Disruption
- Iran war: Strait of Hormuz blockade affects ~20% of global oil supply. Oil hit $100+/barrel within two weeks.
- Ukraine war: Russia’s invasion disrupted ~5-10% of global supply through sanctions. Oil peaked at ~$130/barrel but took several weeks to get there.
Verdict: The Iran war’s oil disruption is more immediate and affects a larger volume of supply.
Gas Price Impact
- Iran war: US gas prices up 17% in two weeks. California above $5/gallon.
- Ukraine war: US gas prices rose ~45% but over several months (Feb-June 2022).
Verdict: The Iran war is driving faster gas price increases, though the Ukraine war ultimately pushed prices higher over a longer period.
Fertilizer and Food
- Iran war: Gulf states produce 49% of global urea and 30% of ammonia. Disruption hits during spring planting season.
- Ukraine war: Russia and Ukraine are major grain and fertilizer exporters. Disruption caused global food price spikes.
Verdict: Both are severe. The Iran war’s fertilizer disruption may be worse due to the Gulf’s dominant share of nitrogen fertilizer production.
Stock Market
- Iran war: S&P 500 fell 0.7% on day one, Dow dropped 400+ points. Airline stocks hit hard.
- Ukraine war: Markets fell 1-2% initially, then recovered within weeks before a longer downturn.
Verdict: Similar initial reactions. Duration will determine which is worse for portfolios.
The Big Picture
The Iran war’s economic threat is more concentrated (energy chokepoint) while the Ukraine war’s was more diffuse (grain, energy, manufacturing). For the average American consumer, the Iran war is producing faster pain at the gas pump and grocery store, but the Ukraine war ultimately had a larger cumulative impact on inflation over 2022-2023.
If the Iran war ends quickly, its total economic damage will be less. If it drags past April, it could surpass the Ukraine war’s impact on US consumers.
