why governments and central banks get worried about inflationary trends?

Answer 1

There are many social costs to higher inflation. Here are just a few of the costs:

1. If prices are increasing, the money that you hold in cash and checking accounts is losing its value. As prices increase faster, the money loses its purchasing power even faster.

2. If prices are increasing, restraunts need to change their prices frequently, catalogs need to be reprinted, web site price lists need to be updated.

3. When prices are increasing or uncertain, employees start asking for larger wage increases that may not reflect their productivity, and they start asking for them more often.

Answer 2

people lose jobs no way to repay.
