Creeping inflation (1-4%)

🌳When the rate of inflation slowly increases over time.

🌳 For example, the inflation rate rises from 2% to 3%, to 4% a year. Creeping inflation may not be immediately noticeable, but if the creeping rate of inflation continues, it can become an increasing problem.

Stagflation

🌳is characterized by slow economic growth and relatively high unemployment—or economic stagnation—which is at the same time accompanied by rising prices (i.e. inflation).

🌳Stagflation can be alternatively defined as a period of inflation combined with a decline in gross domestic product (GDP).
