Following the death of Hugo Chávez in 2013, his successor Nicolás Maduro oversaw the worst crisis in Venezuela's history. The destabilized economy resulted in hyperinflation, an economic depression, shortages in Venezuela and drastic increases in poverty, disease, child mortality, malnutrition, and crime. As a result of the crisis, Venezuela's debt to China and Russia – two political allies – increased. Due to the financial burden of this debt, Venezuela offered Citgo as collateral for Russian debt in 2016, raising the possibility that the Russian government could own Citgo due to Venezuela's high risk of default.
