IPA: //ˈslʌmpfleɪʃən//
KK: /ˈslʌmpfleɪʃən/
A situation in which the economy is experiencing both a decline in growth and an increase in prices.
The country is facing slumpflation, with high inflation rates and a shrinking economy.
Slumpflation is a portmanteau formed from 'slump' (originating from the early 19th century, meaning a sudden fall or decline) and 'inflation' (from Latin 'inflatio', meaning to blow up or swell). The term describes an economic situation characterized by stagnant growth and inflation occurring simultaneously.
Think of a sudden 'fall' ('slump') in the economy while prices are 'swelling' ('inflation') — that's what slumpflation means.
