Frequently Asked Questions

  • What is inflation? Inflation is the rate at which the general level of prices for goods and services rises, reducing purchasing power.
  • How is inflation measured? Primarily through the Consumer Price Index (CPI), which tracks price changes in a basket of common goods and services.
  • What causes inflation? Demand-pull (high demand), cost-push (rising production costs), monetary factors (money supply), and expectations.
  • Is inflation always bad? Moderate inflation (2-3%) is generally healthy for economic growth. Deflation can be more harmful than low inflation.
  • How can I protect against inflation? Invest in real assets (real estate, stocks), inflation-protected bonds (TIPS), and avoid holding too much cash.
  • What's the difference between inflation and deflation? Inflation is rising prices; deflation is falling prices. Both can be problematic in extremes.
  • Why do central banks target 2% inflation? It provides a buffer against deflation while maintaining price stability and allowing for measurement errors.
  • How accurate are inflation calculations? CPI has limitations (substitution bias, quality changes) but provides a reasonable general measure.
