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. Economic problems, as well as crime and corruption, were some of the main causes of the 2014–present Venezuelan protests. Since 2014, roughly 5.6 million people have fled Venezuela.
