1. Caracas, Venezuela.
Kilfedder said, "The economic situation in Venezuela has become increasingly volatile with inflation reaching an astounding 7,000 (seven thousand) percent in the year to March 2018 and 1,800 percent over the last six months alone. The cost of goods has increased exponentially as the economic and political situation has deteriorated and despite the plummeting value of the Bolivar, Caracas sits at the top of our cost of living rankings."
