economy
Over the years, the same amount of money tends to buy a little less than it once did. A small, steady dose of this is considered normal, but when it speeds up it can eat away at your savings surprisingly fast.
Inflation reflects a general, sustained increase in prices across an economy over time, meaning a fixed amount of money gradually loses purchasing power. Central banks typically aim for a small, steady rate because it encourages spending rather than hoarding cash, but when inflation accelerates well beyond that target, it can erode savings surprisingly quickly.
A stock market crash is a separate event involving falling asset prices rather than rising consumer prices, and a jump in factory output describes economic growth, neither of which is what inflation specifically measures.
Because inflation compounds over time much like interest does, even a modest annual rate can significantly erode idle cash left untouched for years, part of why financial planning emphasizes investments that outpace inflation.
