Why is gas so expensive?

  • Even before Russia invaded Ukraine, fuel prices were expected to increase, according to CBS News.
  • While the war in Ukraine is causing a bottleneck in the supply chain, the U.S. is still feeling aftershocks of the pandemic, Deseret News reported.
  • There are several factors that play into fuel costs, such as oil prices, transportation costs, refining costs, distribution and taxes, according to NBC News. The oil fields are also seeing a worker shortage and equipment shortage, which are largely due to pandemic-related reasons, leading to an increase in oil prices and thus an increase in gas prices.
  • “Most of the increase has come from crude oil prices going up, and that’s because the world demand has been coming back quite strongly from the pandemic and supply hasn’t caught up,” said Severin Borenstein, an analyst for Berkeley’s Energy Institute, via CBS News.
  • “Even before Russia attacked Ukraine, we were seeing the production of oil lagging. Producers in the United States are reporting they’re having a hard time getting workers to come back to the oil fields. They’re having supply chain problems with parts and equipment,” said Borenstein.
