Venezuela's annual inflation rate has risen to 63.4%, the highest in Latin America, according to official figures published, BBC reported.
The figures are the first released by the central bank since May, which has led critics to accuse the government of withholding data for political reasons.
The poor state of the economy, among other issues, triggered mass anti-government protests earlier this year.
They have since died down, but many continue to grapple with shortages.
The central bank did not publish its scarcity index, a measure of goods that are missing from store shelves, but shortages of basic items such as flour, milk and toilet paper continue to be the bane of many shoppers.
Protest Slump
While the bank said that month-to-month inflation had eased in August for the third straight month to 3.9%, the annual inflation rate reached a six-year high.
The government of President Nicolas Maduro blamed the soaring inflation on the protests, which rocked the country earlier in the year.
Officials have argued that roadblocks erected by opposition activists hampered trade, and violent clashes between protesters and the security forces often forced shops to close early.
But many international economists argue that massive government spending and exchange rate controls are to blame.
Smugglers' Paradise
Price controls have also ensured that many products are much cheaper in Venezuela than in neighboring Colombia, making the smuggling of goods a profitable business.
The government estimates that 40% of subsidized goods are smuggled into Colombia, further exacerbating shortages in Venezuela.
In an attempt to cut down on smuggling, the two governments agreed in August to close their shared border at night time.
The Venezuelan prosecutor general said more than 350 people had been detained as part of the operation.
The government in Caracas has not yet revealed its gross domestic product (GDP) forecast for 2014, but a number of international economists have been gloomy in their assessment.
London-based economic research consultancy Capital Economics has predicted that Venezuela's GDP will contract by a cumulative 5% in 2014-2015.
It also warned of a "growing risk of a much deeper recession and default".
