Since the government of Hugo Chávez established strict currency controls in 2003, there have been a series of five currency devaluations, disrupting the economy. On 8 January 2010, the value was changed by the government from the fixed exchange rate of 2.15 bolívares fuertes to 2.60 bolívares for some imports (certain foods and healthcare goods) and 4.30 bolívares for other imports like cars, petrochemicals, and electronics. On 4 January 2011, the fixed exchange rate became 4.30 bolívares for US$1.00 for both sides of the economy. On 13 February 2013 the bolívar fuerte was devalued to 6.30 bolívares per US$1 in an attempt to counter budget deficits. On 18 February 2016, President Maduro used his newly granted economic powers to devalue the official exchange rate of the bolívar fuerte from 6.3 Bs.F per US$1 to 10 Bs.F per US$1, which is a 37% depreciation against the U.S. dollar.
