πŸ’Έ What Is Inflation?

Same stuff. Higher prices. But why?

Explore why your money feels like it’s shrinking β€” and what that really says about the economy.

🌐 Background

Inflation is when prices go up over time β€” and the value of money goes down. A cup of coffee that cost $1 in 1990 might cost $3.50 today. That’s inflation in action.

It’s often measured by the Consumer Price Index (CPI), which tracks the average price of a "basket" of goods like food, gas, and housing.

Analogy: Think of your money like a balloon. When inflation rises, the balloon deflates. It doesn’t disappear β€” but it doesn’t stretch as far as it used to.

  • What causes inflation?
  • Is inflation always bad?
  • How do we measure and respond to it?
πŸ“ˆ Additional Info
  • Causes: Inflation can result from increased demand (demand-pull), higher production costs (cost-push), or money supply expansion.
  • Good vs. Bad: Mild inflation encourages spending and growth. High or unpredictable inflation erodes savings and causes instability.
  • Who’s affected: Fixed-income earners and savers lose value; debtors may benefit.
  • Control methods: Central banks raise interest rates to cool inflation.

Example: During the 1970s, the U.S. experienced "stagflation" β€” inflation with slow growth. In the 2020s, inflation surged post-COVID due to supply issues and stimulus.
