🆕The exit of a country from an oil cartel can lead to an increase in oil prices.

The exit of a country from an oil cartel can lead to an increase in oil prices, as the country may not have the same level of access to oil markets and customers. For example, the exit of Qatar from OPEC in 2019 led to an increase in oil prices. The increase in oil prices can have a negative impact on the global economy, as it can lead to a decrease in economic growth. According to a study by Adelman (2019), the exit of a country from an oil cartel can lead to an increase in oil prices of up to 10%.
