That would be true if the government instutition in charge of determining actual inflation wasn't fudging the numbers. I was actually suprised to see people discussing this interest increase like it means something.
Both announced and the expected inflation (especially after the changes in the central bank admin, since May) numbers have been globally recognized both by local independent groups (most known one is ENAG) and international financial institutions. Where did you end up with this idea of inflation number not meaning anything?
