Stagflation is a condition in which slow economic growth (stagnation), rising prices (inflation), and rising unemployment all happen at the same time. Although it is rare for slow economic growth and high inflation to coexist, it has happened in the past, and many believe it could happen again.
Stagflation has occurred twice in the U.S., once between 1974 and 1975 and again between 1978 and 1982. All of this happened during a period known as the Great Inflation (1965 to 1982).
When stagflation is present, workers make less money but have to pay more for the things they buy. Investors see lower returns due to slow growth, and the longer stagflation continues, the more it impacts the future value of their investments. https://fortune.com/recommends/investing/what-is-stagflation/
