Inflation quietly erodes the purchasing power of every dollar you hold, making it a central risk for savers and investors. This guide explains what drives it and how to protect your money.

Key Takeaways

  • What Causes Inflation: Demand-pull inflation: too much money chasing too few goods.
  • Inflation Measurements: CPI measures consumer goods prices.
  • Inflation-Protected Investments: TIPS: Treasury Inflation-Protected Securities adjust principal with CPI.
  • Inflation's Impact on Debt: Inflation benefits fixed-rate borrowers (pay back with cheaper dollars).

What Causes Inflation

Demand-pull inflation: too much money chasing too few goods. Cost-push inflation: rising production costs. Built-in inflation: wage-price spiral. Monetary inflation: increased money supply. Understanding causes helps predict duration and severity.

Key Points:

Demand-pull: excess demand
Cost-push: rising costs
Built-in: wage-price spiral

Inflation-Protected Investments

TIPS: Treasury Inflation-Protected Securities adjust principal with CPI. I-Bonds: government bonds with inflation adjustment. Real estate: rents typically rise with inflation. Commodities: tangible assets preserve value. Stocks: companies can raise prices.

Key Points:

TIPS: principal adjusts with inflation
I-Bonds: government inflation bonds
Real estate: rental income rises
Commodities: tangible value
Stocks: pricing power matters

Inflation's Impact on Debt
