How Inflation Can Affect Investments
Quick answer: Inflation describes a general increase in prices over time, reducing purchasing power when income or assets fail to keep pace.
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.
