Echoes From The Past: What The “Twin Oil Crises” From The 1970s Teach Us About The Coming Impacts Of Hormuz’s Blockade.

The closure of the Strait of Hormuz following escalating tensions between the US and Iran has triggered a global energy crisis reminiscent of the “twin oil crises” of the 1970s. The recent blockade has disrupted a critical energy corridor, causing widespread economic repercussions and a significant shortfall in oil supply. Even if the conflict were resolved swiftly, the damage to infrastructure and lost production will require months or years to restore, highlighting the vulnerability of the fossil fuel-dependent global economy. The twin crises of the 1970s, comprising the 1973 Oil Embargo and the 1979 Islamic Revolution in Iran, provide a historical parallel to today’s situation. The 1973 embargo, initiated by Arab nations in response to Western support for Israel, ended a period of low oil prices by drastically reducing supply and tripling prices within months. The 1979 revolution further compounded the disruption, with Iranian oil production plummeting and prices soaring to unprecedented levels. These events fundamentally altered the global energy landscape, with lasting effects on oil pricing and supply dynamics. Beyond immediate price shocks, the twin crises prompted profound shifts in both supply and demand. On the supply side, they spurred investment in alternative oil sources such as Alaska, the North Sea, and Venezuela, reducing Middle Eastern dominance in global production. Demand-side changes included a near-decade-long stagnation in oil consumption, increased efficiency, and a pivot towards alternative energy sources like nuclear, coal, and gas. These shifts also catalysed innovation in automotive industries, favouring more fuel-efficient vehicles from Japan and South Korea over traditional US models. The lessons from the 1970s suggest that the current Hormuz blockade could similarly reshape the global energy economy. Prolonged disruption may accelerate the transition away from fossil fuels and prompt diversification of supply sources, while also encouraging technological advancements in energy efficiency and alternative power generation. Policymakers and industries may need to prepare for a period of adjustment that challenges established energy dependencies and economic structures, potentially hastening the shift towards more sustainable energy systems.
