risk premium
Risk premium is the extra return an investor demands for taking on a riskier bet instead of a safer, guaranteed one.
In plain English
At the motor park in Jibowu, two drivers are shouting for passengers going to Ibadan. One is a rickety old bus that looks like it survived three accidents already, charging ₦2,500. The other is a shiny new Toyota Sienna, air conditioned, seatbelt working, charging ₦4,000. Some people still board the old bus because it is cheaper, but many pay the extra ₦1,500 because they want the safer ride and their peace of mind is worth that difference.
That extra ₦1,500 is basically a risk premium in everyday clothes. You are paying more, or in investing terms, demanding more, because the risky option could go wrong in ways the safe one will not.
In the stock market, it works the other way round. Instead of paying more for safety, investors demand more return for danger. If Nigerian government treasury bills pay 18 percent because the government is seen as very unlikely to default, then a shaky company's shares need to promise something well above that, maybe 30 percent or more in expected returns, before a reasonable investor bothers to touch it. That gap between the safe rate and the required return on the risky asset is the risk premium.
Someone in London choosing between a UK government bond paying a modest yield and shares in a small, unproven tech company faces the same logic. The tech shares must promise a much bigger potential gain to justify the chance that the company fails and the money vanishes.
Fund managers calculate this constantly. It tells them whether a risky investment is actually paying investors enough for the danger, or whether people are just gambling and calling it investing.
Nigerian treasury bills yield 18 percent. A small manufacturing company's shares are expected to return 27 percent a year if things go well. The risk premium here is roughly 9 percentage points, the extra reward investors want for accepting that the company could struggle, cut dividends, or even collapse, unlike the government which is far less likely to default on its bills.
Questions people ask
Is a higher risk premium always a good thing to see?
Not automatically. It can mean investors are being properly compensated, but it can also signal that a market or company is genuinely troubled and everyone is demanding a much bigger reward before touching it. Context matters more than the number alone.
How is risk premium different from just the interest rate?
The interest rate, or the safe rate, is what you earn on something almost guaranteed, like treasury bills. The risk premium is the extra amount added on top of that safe rate to compensate for the added danger of a riskier investment like shares or corporate debt.
Can ordinary Nigerian investors use this idea practically?
Yes. Before buying any risky stock, compare its expected return to what treasury bills or fixed deposits already pay safely. If the gap feels too small for the risk you are taking, it is a signal to think twice or negotiate a better entry price.
