Secular inflation
Secular inflation is an economic term used to describe a prolonged period of gentle or mild price increases. Secular, or chronic, inflation is basically creeping inflation that continues to persist over a long period of time. Creeping inflation is a term used to describe a gradual rather than drastic increase in prices. Although most commonly used to describe a mild inflation rate, secular inflation can be used to describe most inflation rates that are spread over long periods of time. This type of inflation can be consistent (without many downward movements) or intermittent (occurring at regular intervals).
