A risk premium is the additional return investors expect to earn for taking on higher risk compared with a risk-free investment. It represents the compensation investors demand for accepting uncertainty and potential losses in an investment.
Risk premiums exist because investors generally prefer safer investments. To attract capital, riskier investments must offer the possibility of higher returns.
Understanding risk premium helps investors evaluate whether an investment offers adequate compensation for its level of risk. It also plays a central role in financial theory, portfolio construction, and asset pricing models.
Different asset classes typically carry different risk premiums depending on their volatility and uncertainty.
The risk premium is often calculated as:
Expected Investment Return − Risk-Free Rate
The risk-free rate is typically based on government securities such as Treasury bills.
Higher-risk investments—such as stocks or emerging market assets—generally offer higher potential returns to compensate for the added uncertainty.
If government bonds offer a 3% return and stocks are expected to return 8%, the equity risk premium would be 5%.
Why do investors require a risk premium?
Because riskier investments carry the possibility of loss.
Do all investments have risk premiums?
Most investments beyond risk-free assets include some form of risk premium.
Can risk premiums change?
Yes. They fluctuate based on economic conditions and market sentiment.
