Argentina says 2013 inflation nearly 11 percent, but analysts say it's more like 28 percent

Argentina's government says consumer prices rose 10.9 percent during 2013, but private economic analysts say inflation really was more than twice that.

The inflation figure was reported Wednesday by the INDEC national statistics institute, which has been accused by economists of tweaking the numbers.

This is the last inflation measurement by the INDEC before a new method to calculate consumer prices under the supervision of the International Monetary Fund is released.

Private analysts say inflation topped 28 percent last year, making it the highest in more than two decades.

With consumer prices soaring, Argentines are used to annual labor protests in which workers threaten chaos if they don't get raises.

Union leaders are expected to demand pay hikes of at 30 percent in line with the double-digit inflation rate.
