The literature on the effects of economic shocks on voting behavior has proliferated since the Great Recession. However, evidence beyond the US and European countries is scarce. Carrying out an analysis of the re-organization of the party system in the last Brazilian presidential election, I bring novel evidence to this debate. More specifically, I compute the exposure of Brazilian municipalities to the sharp drop in many commodity prices that began in 2011. I find that in municipalities that were more exposed to the shock, right-wing parties had an advantage in the 2018 presidential election, while left-wing parties lost support. I show that this general trend is unlikely to be explained by anti-incumbency and anti-establishment voting.
