What it means
Valuation works by discounting future cash flows at a rate that reflects their risk. If the same factory is genuinely worth less in a volatile economy than in a stable one, that extra risk has to appear somewhere in the model, and the country risk premium is where it goes.
The most common estimation method starts with the sovereign default spread, which is the extra yield the country's government bonds pay over a benchmark such as US Treasuries. That spread is then scaled up, because equity investors bear more of the country's risk than bondholders do.
The usual scaling factor is the ratio of equity market volatility to government bond volatility in that country. Many analysts simply take a published premium by country rather than rebuilding the calculation, but it is worth understanding what sits behind the figure before relying on it.
Where the premium is applied matters as much as how large it is. Some analysts add it to the cost of equity for every company domiciled in the country, while others weight it by the share of revenue actually earned there, which is fairer for a multinational that happens to be listed in a risky market but sells globally.
The main criticism is double counting. If the cash flow forecasts have already been cut to reflect the chance of expropriation, currency controls or a demand collapse, adding a full country risk premium on top penalises the project twice and can make perfectly sensible investments look worthless.
In practice
Real-world examples
Example 1
A consumer goods group evaluating a new bottling plant abroad adds a 4.5% country risk premium to its cost of equity. The project's internal rate of return of 13% clears the ordinary 9.5% hurdle but fails the country-adjusted 14% hurdle, and the board redirects the capital to a domestic expansion.
Example 2
An investment bank valuing a mining company listed in a high-risk market weights the premium by revenue. Because 70% of sales are made in stable export markets, it applies 30% of the full premium rather than all of it, raising the valuation materially.
Example 3
A private equity fund modelling a healthcare acquisition strips currency risk out of the premium because it plans to fund the deal in local currency debt. It applies only the political and legal component, and documents the reasoning so the investment committee can see what was and was not included.
Think of it
Imagine lending money to a close friend versus lending to a stranger you met at a bus stop. You would charge the stranger a higher rate of interest to make up for the uncertainty of getting paid back.
Formula
Calculation
Country risk premium = Sovereign default spread x (equity market volatility / government bond volatility)
Cost of equity = Risk-free rate + (beta x mature market equity risk premium) + country risk premium
A country's government bonds trade at a spread of 3.0% over US Treasuries. Its equity market has an annual standard deviation of 24% and its government bond market 16%.
Volatility ratio = 24 / 16 = 1.5
Country risk premium = 3.0% x 1.5 = 4.5%
For a project in that country with a beta of 1.10, a risk-free rate of 4.0% and a mature market equity risk premium of 5.0%:
Cost of equity = 4.0% + (1.10 x 5.0%) + 4.5% = 4.0% + 5.5% + 4.5% = 14.0%
Valuing a project generating $10,000,000 a year growing at 2% forever gives 10,000,000 / (14.0% - 2.0%) = 10,000,000 / 0.12 = $83,333,333. Without the premium the discount rate would be 9.5% and the value 10,000,000 / 0.075 = $133,333,333, so the country risk premium removes $50,000,000, or 37.5% of the value.Case study
Seen in the real world
The following is an illustrative and fictional case. Aldermere Foods was weighing a $70,000,000 processing plant overseas, expected to generate $10,000,000 a year growing at 2%. On the group's standard 9.5% cost of equity the project was worth $133,333,333 and looked outstanding.
The treasury team recalculated using a country risk premium. With a 3.0% sovereign spread and a volatility ratio of 24% to 16%, the premium came to 4.5%, lifting the cost of equity to 14.0% and cutting the project's value to $83,333,333. The project still cleared the $70,000,000 cost, but the margin for error had shrunk from $63,333,333 to $13,333,333.
The board approved a smaller first phase rather than the full build, and asked for the cash flow forecasts to be reviewed so that country-specific downside was not being counted twice. The discipline was not that the premium killed the project; it was that a single number turned an obvious yes into a decision worth arguing about.
Watch out
Common mistakes
- Double counting risk by cutting the cash flow forecasts for country-specific problems and then also adding a full country risk premium to the discount rate.
- Applying the premium to every company domiciled in a country regardless of where its revenue and assets actually are.
- Using the raw sovereign spread as the premium without scaling it for the higher volatility of equities relative to government bonds.
Questions
People also ask
Is the country risk premium the same as the sovereign default spread?
No. The spread is the starting point, and the premium is that spread scaled up because equity investors bear more country risk than bondholders.
Should the premium go in the discount rate or the cash flows?
Either can work, but not both. Adjusting cash flows is more precise for identifiable risks such as expropriation, while a premium in the discount rate is simpler and more common.
Does a country risk premium apply to debt as well as equity?
Country risk affects the cost of debt too, but it usually shows up as a higher credit spread on borrowing rather than as this specific equity premium.
