Risk premium
Also written Risk premium adjustment
The extra return an investor demands over the nominal risk-free rate as compensation for uncertainty about future cash flows — the last and largest block in the required rate of return.
In plain language
Some investments promise an amount and a date and deliver both. A government security is the standard example. The return on that certainty is the risk-free rate, and nobody should accept less anywhere else.
Everything else involves doubt — about how much will arrive, and when. The risk premium is the price of accepting that doubt. More perceived uncertainty, higher premium demanded. That is the entire mechanism behind the sentence that unlisted equity must offer more than listed equity, and listed equity more than a treasury bill.
It is a demand, not a promise. The premium is what the investor requires before committing money. Whether it is actually earned is a separate question, and often the answer is no.
How it works
The workbook builds the required rate of return in three blocks, in this order:
- Real risk-free rate — the pure time value of money, the compensation for postponing consumption when there is no inflation and no uncertainty. It is set by the interaction of subjective factors (the desire for current consumption) and objective ones (available investment opportunities and the real growth rate of the economy).
- Expected inflation — because a rupee returned must buy what a rupee lent could. Real rate plus inflation gives the nominal risk-free rate.
- Risk premium — compensation for uncertainty in the amount and the timing of future cash flows.
Real risk-free rate + inflation adjustment + risk premium = Required rate of return
The first two blocks are the same for every investor in the economy at a given moment. Only the third varies by investment, which is why the risk premium is where all the analysis happens.
The inflation step is compounding, not addition. With a real rate of 2% and expected inflation of 6%, the nominal risk-free rate is:
NRR = [(1 + 0.02) × (1 + 0.06)] − 1 = 8.12%
not 8%. The workbook uses these exact figures.
A worked example
An investor is deciding whether to commit Rs 1 crore to a Category III AIF for five years.
Start with the risk-free build-up, using the workbook's own numbers — real risk-free rate 2%, expected inflation 6%:
Nominal risk-free rate = (1.02 × 1.06) − 1 = 8.12%
The investor judges that this fund — leveraged, illiquid, with a lock-in and no daily price — warrants a risk premium of 7%.
Required rate of return = 8.12% + 7% = 15.12%
Now what that premium is worth in rupees over the five years:
| Rate | Rs 1 crore grows to | |
|---|---|---|
| Government security | 8.12% | Rs 1.48 crore |
| This AIF, if it clears the hurdle | 15.12% | Rs 2.02 crore |
1.0812⁵ = 1.4775 1.1512⁵ = 2.0219
The risk premium is worth about Rs 54 lakh of cumulative compensation — and that is the minimum the investor should accept for five years of lock-in and leverage, not a forecast of what the fund will deliver.
Run it the other way and it becomes a screening tool. A fund projecting 12% is offering a premium of only 3.88% over the risk-free rate. For a leveraged, illiquid, closed-ended structure, that is not enough, and the investor should decline without needing any view on the manager at all.
Why NISM asks about it
Chapter 1, sections 1.4, 1.4.1 and 1.4.2 build the required rate of return block by block, and the very first sample question in the workbook asks what the additional return over the normal rate is called — the answer is risk premium, not alpha and not the risk-free rate. Expect the three-component decomposition, the compounded nominal-rate formula, and a question distinguishing required return from expected, forecast, realised and guaranteed return. Chapter 3 then turns the same idea into the market risk premium (Rm − Rf) inside CAPM.
Common exam traps
- Required return is not expected return and neither is realised return. Required is what the investor demands before committing; the workbook stresses that it is not guaranteed or assured.
- The inflation adjustment compounds. 2% real with 6% inflation gives 8.12%, not 8%. Questions are set on precisely this gap.
- Risk premium is not
alpha. The premium is the compensation demanded for bearing risk. Alpha is return earned beyond what that risk justified. - The premium sits on top of the nominal risk-free rate, not the real one. Adding it to the real rate omits inflation and understates the required return.
- A high risk premium is not a good thing to be offered. It means the market judges the cash flows to be highly uncertain. Country risk premiums are highest where the risk is worst.
- The premium is demanded, not delivered. Fifteen per cent required does not mean fifteen per cent earned.

- InflationA sustained general rise in the price level, which erodes what a rupee buys — and the reason a nominal return has to be deflated before it means anything.
- RiskThe possibility that actual returns turn out different from what was expected — measured as the dispersion of returns around their own average, and not the same thing as uncertainty.
