Why inflation matters
Inflation changes real returns, interest rates, wages, company margins, bond values, and household spending. Its effect depends on whether it is expected and whether income or asset cash flows adjust.
How it is applied
Investors compare price indices, wages, expectations, commodity costs, rents, and policy. Portfolio scenarios distinguish demand, supply, currency, and fiscal sources.
Portfolio example
An investment earns 7% while consumer prices rise 4%. Its approximate real return is 3%, before tax and compounding precision.
How to interpret it
Falling inflation is disinflation, while a falling overall price level is deflation. Moderate inflation can coexist with asset losses if rates rise unexpectedly.
Limitations and common misconceptions
Indices differ, personal inflation varies, and hedges are unreliable over short horizons. Regime changes make historical relationships unstable.
