Understand the core concept

Companies may face higher input and labor costs. Some can pass these costs along to customers while others see margins compress.

See how it works

Bondholders may face erosion of the purchasing power of fixed payments. Changing inflation expectations can also affect interest rates and market valuations.

Know the limitations

Stocks, bonds, real assets and cash do not respond to inflation identically or consistently. Short-term relationships are unreliable.

Put it into context

Compare nominal returns with inflation-adjusted purchasing power rather than assuming positive nominal gains always imply growth in real wealth.

Try this yourself

Calculate a fictional 3% nominal return against 4% inflation and discuss purchasing power.
