The Venezuelan government has announced it will replace the country’s highest-denomination banknotes with coins within 72 hours.
It hopes swapping the 100-bolivar notes will help to stop smuggling and tackle shortages of food and other items, the BBC reports.
President Nicolas Maduro said gangs operating in border areas will not have time to repatriate the notes.
His critics dismissed the move as the latest desperate attempt by the President to tackle the economic crisis.
“When ineptitude governs! Who would possibly think of doing something like this in December amid all our problems?” opposition leader, Henrique Capriles, wrote on Twitter (in Spanish).
Others argued it would be impossible to swap all the 100-bolivar notes in circulation in the time allotted.
The 100-bolivar note has lost most of its value over the past few years and is now worth about 2 United States cents (£0.015).
Venezuela, which is facing a serious economic and political crisis, has one of the world’s highest inflation rates.
“I have given the orders to close all land, maritime and air possibilities so those bills taken out can’t be returned and they’re stuck with their fraud abroad,” Mr. Maduro said on television.
