On May 7, 2021, the Colonial Pipeline system was shut down for 6 days in response to a cyberattack. Using daily regular gasoline price data at the city level and employing a difference-in-differences approach to address potential demand-side confounding factors, we find that the shutdown led to a 4 cents-per-gallon increase in average gasoline prices in affected areas, with the estimated impact varying across locations based on their access to alternative means of fuel supply. Although the overall effect was initially slow, it persisted even after the reopening of the pipeline.
