Technically when inflation hits 3 % or 4% is not bad for any country economy . coz always it tends to bust up investment which later promotes more jobs and final improves living standards of the people.
But when inflation hits double digits like 10% . then is only moments people will go to the market with bundles of cash ( money ) in the backet and retunt back to their homes with only few goods in the pocket.
But when inflation hits more than 15% , and cause the price of oil as well as foods to rise up ( like what is happaning right now in Tanzania ) that is when we are going to say this country is experiencing hyper inflation . coz the price will be rising up everyday if any measures of dealing with the situation will no be taken right away.
