In plain words: The rate at which the general level of prices for goods and services is rising.
Inflation describes how quickly everyday prices climb over time. When prices rise, each unit of money buys a little less than before, so the same savings stretch less far. A modest, steady rate is normal in most economies, but persistent inflation quietly erodes the value of money left sitting still.
Why does inflation reduce purchasing power?
If prices rise faster than your savings grow, your real wealth shrinks even though the number in the account looks unchanged. This is why money held only in cash can lose ground in real terms over long periods, despite feeling safe and stable day to day.
Which asset classes can help preserve value?
Historically, broad asset classes that can grow over time, such as global equities and real estate, have tended to outpace inflation across long horizons, while bonds and cash play a steadier role. Outcomes vary and are never guaranteed, but understanding what inflation is helps frame these trade-offs.
Key takeaways
- Inflation is the rate at which general prices rise over time.
- Rising prices erode the purchasing power of money held idle.
- Growth-oriented asset classes have historically helped offset inflation.
