How does inflation affect investment returns?

• A. Inflation erodes purchasing power; investments need to outpace inflation to grow real wealth.
• B. Inflation increases the buying power of money over time.
• C. Inflation only affects cash savings, not investments.
• D. Inflation guarantees higher returns on bonds.

Answer: (A)

Inflation erodes purchasing power, so investments must outpace inflation to grow real wealth. Real return is basically what you earn after removing the effect of rising prices. If your investment earns 7% in a year but inflation is 3%, your purchasing power grows by about 4% (roughly 7% minus 3% in simple terms; a more exact calculation uses (1+nominal)/(1+inflation)−1). If inflation runs higher than your return, your money buys less over time, even though the nominal number on your statement might look positive.

Different assets respond to inflation in different ways. Stocks and some real assets often aim to beat inflation over the long run, but there’s no guarantee in any given year. Cash savings and many fixed‑rate bonds typically don’t keep up when inflation rises, so their real value can shrink. Inflation does not increase buying power, and it does not guarantee higher bond returns; rising inflation can even push bond prices down and reduce real returns.

So the key idea is that inflation reduces what your money is worth in real terms, and your investments need to generate returns that exceed inflation to genuinely grow wealth.
