CARACAS, Sept 7 (Reuters) - Venezuela's monthly inflation rate jumped to 33.8 percent in August, with food price rises reaching hyper-inflationary levels above 50 percent, the opposition-controlled National Assembly said on Thursday.
The government stopped releasing the data more than a year ago amid a deep economic crisis, but the National Assembly has published its own figures since January. They are generally in line with private economists' estimates.
The latest month-on-month inflation figure was a jump from the 26 percent rise in prices reported in July.
In the first eight months of 2017, prices rose a cumulative 366.4 percent, according to the legislative body.
"Food is now in hyperinflation," said opposition lawmaker Angel Alvarado, adding that the food sector had seen price rises of 51 percent in August.
Economists usually define hyperinflation as occurring when monthly rates exceed 50 percent.
Millions of Venezuelans are suffering from food and medicine shortages as the oil producer struggles with an economic crisis that spurred months of nationwide unrest earlier this year.
However, the protests have died down in recent weeks, with many in the opposition viewing them as fruitless after socialist President Nicolas Maduro's government sidelined the National Assembly and created its own legislative superbody.
The country's bolivar currency also weakened past 20,000 per dollar on the widely-used black market on Thursday for the first time. It has lost 95 percent of its value against the U.S. currency in the past year.
The value of $1,000 in local currency purchased when Maduro came to power in April 2013 would now be worth $1.20.
Maduro blames the crisis on the country's opposition and the United States, whom he says are waging an "economic war" against his government.
Critics blame Maduro's economic policies including a currency policy that pegs the bolivar at 10 per dollar at the strongest rate and the strict price controls which they say disincentivize production.
Opponents also point to a rapidly rising money supply. The country's M2 figure is up 431 percent in the last year alone.
The exponential rise in M2 - the sum of cash, together with checking, savings, and other deposits - means an exponential rise in the amount of currency circulating.
Coupled with a decline in the output of goods and services, that has accelerated inflation. (Writing by Girish Gupta; Editing by Paul Simao)
