Inflation: The Quiet Tax on Standing Still

Why cash slowly shrinks, and what that means for parked money.

Inflation is prices rising over time, measured monthly by the Bureau of Labor Statistics' Consumer Price Index. At 3% a year, today's $100 buys about $74 worth in ten years. Nothing was taken; it just quietly buys less.

This is why account CHOICE matters even for safety money: the gap between a 0.1% branch account and a competitive high-yield rate is the difference between shrinking faster and roughly keeping pace in many years.

It's also the honest argument for eventually investing LONG-term money: past the emergency fund, all-cash is not 'no risk'; it's a slow guaranteed loss to inflation traded against the market's fast unguaranteed swings. Both risks are real; adults pick theirs deliberately.
