1979 oil crisis
The 1979 oil crisis, sometimes referred to as the second oil crisis (in reference to the 1973 oil crisis), refers to the drop in oil production in the aftermath of the Iranian Revolution that led to an energy crisis in 1979. Although the global oil supply only decreased by approximately four percent, the oil markets' reaction raised the price of crude oil drastically over the next 12 months, more than doubling it to $39.50 per barrel ($248/m3), equivalent to $175 per barrel ($1,101/m3) in 2025.
