Using Scenarios instead of Country Risk Premia

In recent blogs, we have discussed whether country risk is diversifiable and if risk premia for emerging markets are overstated. While our analysis does not really prove that there is no country risk premium, it's clear that common numbers are way overstated. We would therefore argue that adding CRP is not the best way to value a project in emerging markets (or anywhere).
In the end, we are trying to estimate the expected cash flows of the project or the business. If we do that correctly, the risk is taken care of. So in many cases, a much better approach for determining the expected value of a project is to develop multiple business, risk, and cash-flow scenarios, preferably including at least one downside case, value them at the unadjusted cost of capital, and then calculate the average weighted by the probability that each will happen (Exhibit 1).

Practically, the cost of capital should be estimated using the same approach as in developed countries. To estimate the risk free rate, we recommend using the USD risk free rate and ?adding an inflation differential to the local currency. The market risk premium should also be considered with the perspective of a global investor at ~5%. The most important aspect here is consistency in assumptions for cash flow forecasts and cost of capital (e.g., in terms of inflation assumption)
This approach not only provides decision makers with more information about the risk, it also encourages managers to develop strategies to mitigate specific risks?and acknowledges the full range of possible outcomes (not only where everything goes well). In a recent set of interviews, we also found that practitioners see the value in the discussion of the risk, the mitigation opportunities, and the impact - not in the actual probabilities. This makes sense - you will never be able to nail down the exact probabilities, and there is a big danger to get stuck in the attempt to do the perfect. The risk discussion based on scenarios, however, is highly valuable for decision makers.
(This article by Ryan Davies , Tim Koller , and Marc Goedhart has more details on the scenarios approach)
Adding an extra country risk premium to the cost of capital doesn’t add insight; it obscures it.?Scenario-based approaches have the dual appeal of better answers and more transparency on the assumptions embedded within them.

1 年I like this. Broadly speaking, we should maximally try to quantify the actual (especially nondiversifiable) risks, whether with scenarios or probability distributions or whatever is appropriate, and do that in preference to adding artificial, unjustified risk premia. Having defeated the country risk premium, the natural outgrowth of this type of thinking sets its sights on the 5% equity market risk premium itself. Hypothetically, if we had perfect insight as to all fundamental risks in the investment, should we be whittling it down to zero? Put in other words, if we probability weight NPVs across all "reasonable" risk scenarios, and those NPVs use a market risk premium of 5% (forget about developing vs developed markets now), how much risk are we double-penalizing for? I've asked this of both academics and valuation practitioners and never quite gotten a solid answer, just partial ones. (Finally, there's a typo in your link to the "adding inflation differential" blog post. It should be https://www.mckinsey.com/capabilities/strategy-and-corporate-finance/our-insights/the-strategy-and-corporate-finance-blog/estimating-cost-of-equity-when-inflation-is-high (remove the + that is in the link in the article text above)
