What History Tells Us About Oil Shocks: Lessons for Today’s Crisis

History offers both warning and guidance as the world confronts one of the most severe oil price shocks in decades. The Iran conflict’s more than 25% weekly surge in Brent crude — to above $91 a barrel, the biggest weekly gain since the Covid-19 pandemic — has historical parallels that illuminate both the potential severity of the current situation and the conditions under which oil shocks typically end.
The 1973 Arab oil embargo remains the archetype of a geopolitical oil shock. Within months of the embargo’s start, oil prices had quadrupled, triggering recessions in major importing economies, and contributing to a decade of stagflation. The lesson from 1973 is that oil shocks driven by deliberate political action can be sustained as long as the political will to sustain them exists — and that their economic consequences can be severe and lasting.
The 1990 Gulf War oil spike offers a different lesson. Oil surged dramatically when Saddam Hussein invaded Kuwait, but quickly reversed when the military intervention proved swift and decisive. The lesson from 1990 is that oil shocks driven by military conflict can reverse quickly if the conflict is resolved — but that the reversal requires a clear and credible military outcome, not just diplomatic statements.
The post-Covid oil surge of 2021-2022 offers yet another lesson: that supply-side oil shocks can be remarkably persistent, lasting much longer than initial forecasts suggest. The combination of constrained Gulf production, damaged LNG infrastructure, and closed shipping lanes in the current crisis has structural parallels to the supply chain disruptions of 2021-2022 — suggesting that the price impact could persist even if the military conflict is resolved relatively quickly.
Kuwait has cut production, Saudi Arabia and UAE face storage exhaustion within 20 days, and Qatar’s minister warns of $150 oil if all exporters halt. Financial markets have already registered their alarm. History’s lesson is that oil shocks rarely resolve as quickly as hoped, that their inflationary consequences tend to be underestimated in the early stages, and that the economic damage they inflict accumulates over time. Policymakers and investors would do well to plan for a crisis that lasts longer than they currently expect.
