Abstract This study evaluates the economic impact of the 2017 Qatar blockade using synthetic control methods. The analysis shows that Qatar’s GDP in 2022 was approximately 24 % lower than without the blockade, equating to a loss of 82 billion international dollars in 2017 constant prices. Despite Qatar’s proactive strategies, including trade diversification and infrastructure investment, the economic cost remains substantial. Short-term financial commitments and resource reallocation to mitigate the blockade’s effects likely strained public finances and slowed growth. The study underscores the economic toll of the blockade and suggests further research into the long-term effects of Qatar’s policy responses.
