Why Do Gas Prices Swing Like Crazy?

Gasoline prices are among the most volatile and frustrating for consumers, fluctuating due to supply-and-demand shifts, government actions, and market predictions.
As one of the main economic drivers, the worldwide market value of crude oil is behind many gas price fluctuations. At the same time, worldwide oil trading leads to prices changing constantly as market information motivates both producers and consumers.
Market volatility also arises from the refining process. Since many places including the U.S. don’t have the extra refining capacity to quickly increase gasoline production if there is a spike in consumer demand, prices will go up as supply trails behind.
Additionally, seasonal demand shifts, such as increased travel in summer, or more need for heating in the winter, causes the price of gas to change throughout the seasons.
Many fuel producers are under constant threat from competitors because different stations offer nearly identical products with their own unique characteristics. Gas stations increase their prices rapidly when wholesale costs rise to maintain profit levels; however, the price decreases at a slower rate, demonstrating a "rockets and feathers" pattern where prices rise quickly but fall gradually.
Prices may also change based on people's predictions about upcoming supply and demand patterns. When investors predict that future supply will be insufficient, the market price increases immediately, reacting to any news about conflicts or OPEC statements before actual changes occur. The price of gasoline stands as one of the few consumer products which shows immediate market price reactions to worldwide market expectations.
The worldwide nature of oil trading creates a global market system which demonstrates international market connections. The U.S. gasoline prices experience immediate changes due to events occurring in Middle Eastern countries, Russia, China, and European nations. Domestic prices respond quickly to international market disturbances when a vital input is part of global trade networks.
Market dynamics shift based on consumer usage patterns of gasoline, which remain relatively stable despite price changes, leading to inelastic demand, meaning people will buy no matter what. Short-term demand for gasoline remains insensitive to price changes because people need to drive and heat their homes and operate their vehicles. The lack of demand response to price increases leads to more pronounced price increases when supply shortages occur. Markets also show inelastic demand because consumers maintain their gasoline consumption despite price changes, making substantial price fluctuations more common as consumers are willing to accept them. The market experiences larger-than-usual price fluctuations because consumers lack the ability to reduce their gasoline consumption which forces prices to absorb all market changes.
Gasoline is a pillar of society, and without it many of the gears that run the world would stop. As a result, prices can be unstable, caused by myriad factors, as analysts and consumers try to move forward with this confusing, but essential industry.
