Venezuela's government has announced it is devaluing the country's currency, a change expected to push up prices in the heavily import-reliant economy.
Officials on Friday said the fixed exchange rate is changing from 4.30 bolivars to the US dollar to 6.30 bolivars to the dollar.
The devaluation had been widely expected by analysts in recent months, though experts had been unsure about whether the government would act while President Hugo Chavez remained out of sight in Cuba recovering from cancer surgery.
It was the first devaluation to be announced by Chavez's government since 2010.
Planning and Finance Minister Jorge Giordani said the new rate would take effect on Wednesday, after a two-day banking holiday.
He said the old rate would still be allowed for some transactions that already were approved by the state currency agency.
Venezuela's government has had strict currency exchange controls since 2003 and maintains a fixed, government-set exchange rate.
Under the controls, people and businesses must apply to a government currency agency to receive dollars at the official rate to import goods, pay for travel or cover other obligations.
While those controls have restricted the amounts of dollars available at the official rate, an illegal black market has flourished and the value of the bolivar has recently been eroding.
In black market street trading, dollars have recently been selling for more than four times the official exchange rate of 4.30 bolivars to the dollar.
The devaluation brought down the official value of the bolivar by 46.5 per cent against the dollar.
The announcement came after the country's Central Bank said annual inflation rose to 22.2 per cent in January, up from 20.1 per cent at the end of 2012.
