In March 2020, global crude oil prices tumbled from over $50 a barrel to below $23 per barrel, bringing prices to their lowest level in nearly two decades. This precipitous drop in crude oil prices was fueled by two major shocks to the oil market. First, the COVID-19 pandemic led to a massive reduction in all forms of travel as large numbers of people around the world were advised to shelter in place. Second, Russia, Saudi Arabia, and a number of other major oil-producing nations typically reach collective agreements to limit the world supply of oil in order to keep prices high, but these negotiations broke down in March 2020, prompting a sharp increase in oil production. Using a supply and demand graph, show how each of these factors affected the market price and quantity of crude oil.
