of Leopoldo López. In the 2015 Venezuelan parliamentary election, the opposition gained a majority. Venezuela devalued its currency in February 2013 due to rising shortages in the country, which included those of milk, flour, and other necessities. This led to an increase in malnutrition, especially among children. Venezuela's economy had become strongly dependent on the exportation of oil, with crude accounting for 86% of exports, and a high price per barrel to support social programs. Beginning in 2014 the price of oil plummeted from over $100/bbl to $40/bbl a year and a half later. This placed pressure on the Venezuelan economy, which was no longer able to afford vast social programs. To counter the decrease in oil prices, the Venezuelan Government began taking more money from PDVSA, the state oil company, to meet budgets, resulting in a lack of reinvestment in fields and employees. Venezuela's oil production decreased from its height of nearly per day. In 2014, Venezuela entered an economic recession. In 2015, Venezuela had the world's highest inflation rate with the rate surpassing 100%, which was the highest in the country's history. In 2017, Donald Trump's administration imposed more economic sanctions against Venezuela's state-owned oil company PDVSA and Venezuelan officials.

In September 2016, a study published in the Spanish-language Diario Las Américas indicated that 15% of Venezuelans are eating "food waste discarded by commercial establishments". Close to 200 riots had occurred in Venezuelan prisons by October 2016, according to Una Ventana a la Libertad, an advocacy group for better prison conditions. The father of an inmate at Táchira Detention Center in Caracas alleged that his son was cannibalized by other inmates during a month-long riot, a claim corroborated by an anonymous police source but denied by the Minister of Correctional Affairs.
