There will always be inflation. However getting 10% inflation is not normal. It hurts many people living pay check to pay check and those that are savers.
Sometimes, a moderate amount of inflation is considered healthy for the growth of an economy. But, yes, inflation touching double figures is always bad news for the people as the commodity prices will increase, and the buying power will decrease, hence the devaluation of the currency. It is also not good for the economic growth of a country.
Normally you should never hold cash in the bank. You need to have it in some form of investments such as stocks or even bonds. Right now you can get 5% with most bonds and it’s risk free pretty much. So with the inflation we got right now, you are pretty much breaking even.
Saving money in Bank accounts is a suicide. You should only have a small amount in your bank account for day-to-day purchasing. Bonds are the best option, I think, if the person is not willing to take the risk. Other options, such as Gold, Silver, Property, etc. can also be considered. At the moment, inflation is a global phenomenon, and people are living paycheck to paycheck in most countries.
