risk-free rate

The theoretical rate of return of an investment with zero risk, typically approximated by short-term US Treasury bill yields.

Example

“With 3-month Treasury bills yielding 5%, investors demanded returns above this risk-free rate to justify any risky investment.”

Memory Tip

RISK-FREE RATE = what you earn with ZERO risk. T-bills approximate this. Everything else must beat it.

Why It Matters

The risk-free rate serves as a benchmark for all other investments, helping you understand what return you could guarantee with zero risk. It directly influences how much extra return you should demand from stocks, bonds, and other investments to compensate you for taking on additional risk.

Common Misconception

Many people believe the risk-free rate is truly risk-free in all circumstances, but this ignores inflation risk and the fact that even US Treasury securities can lose value if interest rates rise. The only way to achieve the stated return is to hold the security until maturity.

In Practice

If a 3-month US Treasury bill yields 5.5 percent annually, that becomes your risk-free rate baseline. If you are considering investing in a corporate bond offering 7 percent, you would expect that extra 1.5 percent premium to compensate you for the credit risk that the company might default.

Etymology

RISK-FREE (without uncertainty of loss) RATE (return percentage). The RATE of return with no RISK.

Common Misspellings
