The country risk premium (CRP), sometimes called the political risk premium, is the additional return that investors require above the risk-free rate to compensate for the incremental risks of investing in a specific country compared to a mature, stable market such as the United States. Country risk encompasses political instability, the risk of government expropriation or nationalization, corruption, war and civil unrest, weak rule of law, currency inconvertibility, sovereign default risk, and macroeconomic mismanagement. In valuation practice, the CRP is added to the equity risk premium when estimating the cost of equity for companies operating in or exposed to higher-risk markets. The most widely used framework, developed by Professor Aswath Damodaran of NYU Stern, calculates CRP as the product of the country's default spread (measured by sovereign CDS spreads or sovereign bond yield differentials) and an equity risk adjustment factor reflecting the greater volatility of equities relative to bonds. For example, if a country's sovereign bonds trade at 300 basis points above US Treasuries and local equity markets are 1.5 times as volatile as the local bond market, the CRP would be 300 × 1.5 = 450 basis points. The EMBI+ (Emerging Market Bond Index) spread, compiled by J.P. Morgan, is the most commonly used source for sovereign default spreads. Political Risk Services (PRS), Moody's, S&P, and Fitch provide systematic country risk ratings. The CRP is essential for discounted cash flow (DCF) valuation of projects and companies in emerging and frontier markets, affecting everything from oil field development economics to infrastructure project financing.
Political Risk Premium Calculation: Step 1: Obtain the country's sovereign bond yield spread over comparable US Treasury maturities (or use CDS spreads). Step 2: Collect the annualized volatility of the country's equity market index and its sovereign bond index. Step 3: Calculate the equity-to-bond volatility ratio: σ_equity / σ_bond. Step 4: Compute the CRP: CRP = Default Spread × (σ_equity / σ_bond). Step 5: Add the CRP to the mature market equity risk premium to get the total ERP for that country. Step 6: Adjust for the specific company's exposure (lambda): Company CRP = λ × CRP. Step 7: Use the adjusted cost of equity in DCF valuation: Ke = Rf + Beta × ERP_mature + λ × CRP. Each step builds on the previous, combining the component calculations into a comprehensive political risk premium result. The formula captures the mathematical relationships governing political risk premium behavior.

Damodaran methodology; updated January 2024
Brazil's 200 bps sovereign spread is amplified by the equity-to-bond volatility ratio of 22/12 = 1.83, giving a CRP of approximately 3.67%. Adding this to the mature market ERP of 5.0% yields a total equity risk premium for Brazil of 8.67%. A company with all operations in Brazil would use this premium, while a multinational with 30% Brazil exposure would apply only 30% of 3.67% = 1.1% additional premium.
Very high CRP reflects political instability and oil sector risks
Nigeria's high sovereign CDS spread of 600 bps reflects concerns about oil revenue dependency, governance, and regional security. Amplified by the equity-to-bond volatility ratio of 1.87, the CRP reaches 11.2%, pushing the required equity return to potentially 18–22% when combined with a risk-free rate and beta. This extraordinarily high hurdle rate explains why many international oil companies require above-normal returns before investing in Nigerian upstream projects.
Lambda = 40% applied only to the India-specific portion of the CRP
The company derives 40% of revenues from India, so only 40% of India's CRP of 2.80% = 1.12% is added to its cost of equity. The base cost from beta and the mature market premium is 4.50% + 5.50% = 10.0%, and the India adjustment adds 1.12%, bringing the blended cost of equity to 11.12%. This reflects the portfolio effect: the company's US and other revenues diversify away most of the country-specific risk.
Illustrates extreme political risk; war context
CDS spreads can be converted to implied default probabilities using the formula: PD ≈ Spread / (1 − Recovery Rate). At a 1,500 bps CDS spread and 40% recovery assumption, the annual default probability is approximately 25%, implying roughly 76% cumulative probability of default over 5 years. This was reflective of Ukrainian sovereign CDS levels during the 2022-2023 conflict period, illustrating how political risk translates directly into pricing.

{'case': 'Expropriation risk in resource sectors', 'description': 'Mining, oil, and infrastructure projects face elevated political risk because host governments may renegotiate contracts or nationalize assets when commodity prices rise and the resource rent becomes highly visible. Savvy project developers structure transactions with multilateral lenders and use production-sharing agreements that align government interests with project success.'}
In the Political Risk Premium, this scenario requires additional caution when interpreting political risk premium results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when political risk premium calculations fall into non-standard territory.

What are the main components of country risk?
Country risk typically comprises several dimensions: political risk (government stability, policy continuity, expropriation risk, war, and civil unrest), economic risk (fiscal position, current account, debt levels, inflation, and growth outlook), financial risk (currency convertibility, banking system stability, external debt service capacity), and operational risk (rule of law, corruption, infrastructure, and regulatory environment). Rating agencies like Moody's, S&P, and PRS Group provide composite country risk scores that aggregate these dimensions.
How often does Damodaran update country risk premiums?
Professor Aswath Damodaran of NYU Stern publishes updated country risk premiums on his website typically at the beginning of each year (January) and sometimes mid-year for countries experiencing significant risk changes. His dataset covers over 170 countries and is freely available, making it the most widely used academic and practitioner reference for country risk premiums in DCF valuations. The data includes default spreads, equity risk premiums, and cost of equity estimates by country.
What is the difference between political risk and sovereign risk?
Sovereign risk specifically refers to the risk that a government will default on its debt obligations — the inability or unwillingness to service sovereign bonds. Political risk is broader and encompasses all risks arising from the political environment, including expropriation of private assets, breach of contracts, currency inconvertibility, import restrictions, civil war, and regulatory changes that harm investors. A country can have manageable sovereign risk (debt service ability) while still presenting high political risk to foreign direct investors through expropriation or regulatory instability.
How do political risk insurance providers work?
Political risk insurance (PRI) is offered by multilateral institutions (World Bank's MIGA), export credit agencies (OPIC/DFC in the US, UKEF), and private insurers (Lloyd's market, AIG, Zurich). PRI covers specific risks including expropriation, currency inconvertibility, political violence, and breach of contract by the government. Premiums typically range from 0.5% to 3% of insured value annually, depending on country, sector, and coverage type. MIGA's involvement also provides a deterrence effect, as few host governments want to trigger a dispute with the World Bank group.
How do multilateral development banks (MDBs) reduce country risk?
Multilateral development banks like the World Bank, IFC, EBRD, and ADB reduce country risk for private investors through several mechanisms: partial risk guarantees (covering specific political risks), B-loan programs (where private banks lend alongside MDBs, inheriting some of their preferred creditor status), equity investments alongside private sponsors, and technical assistance that builds institutional capacity. The MDB 'umbrella' effect can reduce the required risk premium by 2–4 percentage points for projects in their portfolio.
What is the EMBI+ and how is it used?
The Emerging Market Bond Index Plus (EMBI+), created by J.P. Morgan, tracks the total return on USD-denominated sovereign and quasi-sovereign bonds from emerging market countries. The spread of EMBI+ bonds over comparable US Treasuries is the most widely used proxy for sovereign default risk. Country-level EMBI spreads are the primary input for the Damodaran CRP calculation. Countries with investment-grade ratings typically show EMBI spreads of 50–200 bps, while distressed sovereigns can trade at 500–1,500+ bps.
Can country risk be diversified away in a global portfolio?
Country-specific idiosyncratic risks (a single country's political event) can be substantially diversified in a well-diversified global portfolio. However, global systematic risks — worldwide recessions, global financial crises, or pandemic-level events — affect all countries simultaneously and cannot be diversified away. Empirically, country risk premiums are partially correlated across emerging markets because global risk appetite affects all of them together. The diversification benefit of adding a single high-risk country to a global portfolio is real but limited.

For companies with revenues diversified across multiple emerging markets, calculate a weighted average CRP based on revenue shares in each country (lambda weighting) rather than applying a single country's CRP to the entire enterprise.

Argentina has defaulted on its sovereign debt nine times since independence, more than any other country in history. Despite this, international investors have repeatedly returned to buy Argentine bonds at attractive spreads, creating what economists call the 'Argentine paradox' of persistent sovereign borrowing despite serial default.
