What major economic event in 1973 caused gas shortages in the U.S.?

The major economic event in 1973 that caused gas shortages in the U.S. was OPEC's production cut. During this time, the Organization of the Petroleum Exporting Countries (OPEC) decided to reduce oil production significantly. This decision was a response to political tensions in the Middle East, particularly following the Yom Kippur War, and aimed to leverage oil as a tool for political influence and economic pressure.

The effect of the production cut was immediate and severe, leading to a dramatic increase in oil prices worldwide. As prices surged, American consumers faced long lines at gas stations and limited fuel availability, which resulted in widespread gas shortages.

Understanding this event underscores the interconnectedness of geopolitics and economics, illustrating how decisions made in one part of the world can have far-reaching consequences on daily life in another, particularly in terms of energy supply and pricing.
