Up until the late 1960s, the U.S. extracted most of its oil at home and didn’t rely much on foreign sources. But after domestic oil production peaked in 1970, the U.S. began importing more oil from other countries. By 1973, OPEC provided 30 percent of America’s oil. The cartel had existed since 1960, when five nations—Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela—banded together to control the supply and price of oil and secure fair prices for producers.
In October 1973, Egypt and Syria launched a surprise attack on Israel, in what became known as the “Yom Kippur War.” The U.S., an ally of Israel since its founding in 1948, supported Israel by supplying it with weapons and money.
To retaliate, OPEC announced a 5 percent monthly decrease in oil output and stopped exporting oil to the U.S. and later to other nations, including the Netherlands, Portugal, and South Africa. As a result, U.S. oil prices quadrupled, from about $3 a barrel to nearly $12 a barrel. Within a few months, gas prices soared by 40 percent.
Afraid that gas stations would run out of fuel, Americans began panic buying to try to keep their tanks full. Fights broke out at pumps, and some people stole fuel out of cars. Long lines snaked around the block, sometimes for miles.
