SkimNews Take
A 7-for-7 historical record sounds damning, but the framing conflates correlation with causation—blurring whether oil itself drags markets down or merely shares the same geopolitical trigger already punishing them.

- Israel and Iran have traded attacks on key energy infrastructure during the three-week war, triggering fresh spikes in oil and natural gas prices.
- Brent crude was trading around $105 a barrel as of March 20, up 50% from pre-war levels.
- The S&P 500 is down 5% this month and just finished its fourth straight losing week, while the Nasdaq Composite is approaching correction territory (a 10%+ pullback).
- The duration of elevated oil prices hinges on whether the Strait of Hormuz reopens and the extent of lasting damage to Gulf energy infrastructure.
- Since 1973, seven oil spikes of 40% or more have each preceded an S&P 500 bear market — except in 1979 and 2011, when the index only approached one.
- The market entered the war already fragile, with only about 200,000 jobs added in the past year, stubborn inflation, rising household debt, weak consumer sentiment, and a historically expensive S&P 500.
Why it matters: The S&P 500 entered this war with historically expensive valuations, anemic job growth, and weak consumer sentiment — making it more vulnerable to an oil shock than in prior episodes. With every major oil spike since 1973 (except two) ending in a bear market, sustained energy disruption could expose pre-existing cracks and tip a fatigued bull market into a full retreat.
