Chávez also remained in power after an all-out national strike that lasted from December 2002 to February 2003, including a strike/lockout in the state oil company PDVSA. The strike produced severe economic dislocation, with the country's GDP falling 27% during the first four months of 2003, and costing the oil industry $13.3 billion. Capital flight before and during the strike led to the reimposition of currency controls (which had been abolished in 1989), managed by the CADIVI agency. In the subsequent decade, the government was forced into several currency devaluations. These devaluations have done little to improve the situation of the Venezuelan people who rely on imported products or locally produced products that depend on imported inputs while dollar-denominated oil sales account for the vast majority of Venezuela's exports. According to Sebastian Boyd writing at Bloomberg News, the profits of the oil industry have been lost to "social engineering" and corruption, instead of investments needed to maintain oil production.
