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.
