Sources Of Country Risk

• Understanding sovereign default risk is crucial for setting interest rates on sovereign bonds and loans, as well as for pricing all other assets. Governments can default for similar reasons as individuals and firms: they often borrow more than they can afford, particularly during economic booms, and then struggle to meet their debt obligations during downturns. Assessing sovereign default risk involves evaluating various economic, political, and social factors that contribute to a country’s ability to meet its debt obligations. Some of the sources of country risk are as follows –
  1. Degree of Indebtedness: This involves assessing how much a sovereign entity owes relative to its GDP. Higher debt levels can indicate a higher risk of default, especially if the debt levels are unsustainable. The degree of indebtedness includes both foreign and domestic debt. Countries with higher debt-to-GDP ratios may struggle to meet their debt obligations, particularly during economic downturns. For instance, Venezuela’s government debt climbed from 25% of GDP to more than 300% between 2010 and 2020, indicating a high risk of default.
  2. Pensions/Social Service Commitments: Governments often have significant commitments to pay pensions and provide healthcare. These obligations compete with debt service for limited government revenues. Countries with larger social service commitments, especially with aging populations, may face higher default risks due to the increased financial burden. For example, countries with aging populations like Japan may struggle more to meet their financial obligations.
  3. Revenues/Inflows to Government: Government revenues primarily come from taxes. The size and efficiency of the tax base directly impact the government’s ability to generate revenue to meet its debt obligations. A larger and more robust tax base generally reduces default risk. For example, a country with a strong and broad tax base like Germany is less likely to default compared to a country with a smaller tax base.
  4. Stability of Revenue: Revenue stability is crucial for managing fixed debt obligations. Countries with diversified economies tend to have more stable revenue streams, reducing default risk. Conversely, economies heavily reliant on specific sectors or commodities face higher risks due to revenue volatility. Additionally, the type of tax system can affect revenue stability, with income tax systems generally being more volatile than sales tax systems. For example, Peru, reliant on copper and silver, faces more revenue stability risks compared to a diversified economy like India.
  5. Political Risk: The likelihood of default is influenced by political factors. Autocracies, with less accountability to the public, might be more prone to default than democracies. The independence and strength of the central bank also play a role, as politically influenced decisions can lead to poor economic management and higher default risk. For instance, countries with unstable political environments may face higher default risks.
  6. Implicit Backing from Other Entities: The perceived or actual support from stronger economies or international entities can affect a country’s default risk. For example, countries in economic unions may be viewed as less risky due to potential support from stronger member states. However, this backing is often implicit and not guaranteed, which can lead to disappointments and increased risk if the support does not materialize. The example of Greece in the European Union illustrates how implicit backing can influence risk perceptions.

Methods For Assessing Country Risk

• Measuring country risk is essential for investors and companies considering international investments. Several methods are commonly used to assess country risk, each with its strengths and limitations. Here are the primary methods and their respective limitations:
  1. Sovereign Credit Ratings: Agencies like Standard & Poor’s, Moody’s, and Fitch provide ratings that reflect a country’s creditworthiness.Limitations:
     1. Subjectivity: Ratings can be influenced by the subjective judgment of the rating agency.
     2. Lag in Response: Ratings may not be updated promptly in response to rapid changes in a country’s economic or political environment.
     3. Conflict of Interest: Agencies might face conflicts of interest, especially when they are paid by the entities they rate.
  2. Economic Indicators: Economic indicators such as GDP growth, inflation rates, current account balance, and fiscal deficits provide insights into a country’s economic health.Limitations:
     1. Data Quality: Reliability of economic data can vary significantly between countries.
     2. Time Lag: Economic data is often reported with a delay, reducing its usefulness in real-time decision-making.
     3. Narrow Focus: Economic indicators alone may not capture broader risks like political instability or social unrest.
  3. Political Risk Analysis: Analysis of political stability, government policies, corruption levels, and geopolitical risks.Limitations:
     1. Subjectivity: Political risk analysis can be highly subjective and influenced by the analyst’s perspective.
     2. Complexity: Political landscapes can be complex and rapidly changing, making accurate predictions difficult.
     3. Qualitative Nature: Much of political risk analysis is qualitative, which can be hard to quantify and compare objectively.
  4. Country Risk Indices: Composite indices (e.g., the Economist Intelligence Unit’s Country Risk Ratings, Euromoney’s Country Risk Survey) combine various factors to provide an overall risk score.Limitations:
     1. Weighting Issues: The relative importance assigned to different risk factors may not accurately reflect their true impact.
     2. Over-Simplification: A single index score can oversimplify the nuanced risks present in a country.
     3. Source Bias: Different indices may use different sources and methodologies, leading to inconsistent results.
  5. Qualitative Assessment: Expert judgment and qualitative analysis based on interviews, surveys, and expert opinions.Limitations:
     1. Bias and Subjectivity: Personal biases and the subjective nature of qualitative assessments can affect accuracy.
     2. Consistency: Maintaining consistency across different assessments can be challenging.
     3. Non-Quantifiable: Qualitative factors can be difficult to quantify and integrate into financial models.
  6. Market-Based Indicators: Financial market indicators such as bond spreads, credit default swap (CDS) spreads, and stock market performance.Limitations:
     1. Market Sentiment: Market-based indicators can be influenced by short-term market sentiment and may not reflect underlying fundamental risks.
     2. Volatility: Financial markets can be volatile, leading to rapidly changing risk assessments.
     3. Speculation: Speculative trading can distort market indicators, making them less reliable.
  7. Economic Freedom Indices: Indices such as the Heritage Foundation’s Index of Economic Freedom measure economic freedoms like property rights, regulatory efficiency, and open markets.Limitations:
     1. Ideological Bias: The criteria and weighting of these indices can reflect the ideological biases of the organizations creating them.
     2. Static Nature: These indices are updated annually and may not capture real-time changes in economic policies or conditions.
     3. Narrow Focus: They often emphasize economic factors and may not fully account for political and social risks.
• Each method for measuring country risk has its advantages and drawbacks. A comprehensive country risk assessment often involves using a combination of these methods to obtain a more balanced and accurate picture. Despite their limitations, these methods collectively help investors and companies make informed decisions about international investments and operations.

Foreign v Local Currency Defaults

• Foreign currency defaults and local currency defaults are two distinct types of sovereign debt defaults. Each has its own characteristics, implications, underlying causes and challenges.

Foreign Currency Defaults

• Characteristics:
  1. Nature of Debt: Debt borrowed from other countries or foreign banks, typically denominated in a foreign currency.
  2. Reasons for Default: Occurs when a country is short of the required foreign currency to meet its obligations. Countries cannot print foreign currency, which limits their ability to manage these debts.
  3. Market Perception: Typically, foreign currency debt is considered riskier because it depends on the country’s ability to generate or acquire foreign currency.
  4. Historical Examples: Frequent occurrences include Argentina (Dec-89, Nov-01), Venezuela (Jul-98), Russia (Aug-98), Ukraine (Sep-98), and Greece (Mar-12).
  5. Magnitude: The defaulted debt can be substantial, such as Greece’s $264,211 million default in Mar-12.
• Causes:
  1. Exchange Rate Volatility: Depreciation of the local currency can increase the cost of servicing foreign currency debt.
  2. Foreign Reserve Depletion: Insufficient foreign exchange reserves can lead to an inability to meet debt obligations.
  3. Economic Shocks: External economic shocks, such as a drop in commodity prices or a global financial crisis, can reduce foreign currency earnings.
• Implications and Challenges:
  1. Currency Mismatch: The primary challenge is the inability to print foreign currency. Countries must rely on their foreign exchange reserves or secure additional foreign funding.
  2. Economic Impact: Defaults in foreign currency can lead to severe economic repercussions, including a loss of investor confidence and increased borrowing costs.
  3. Dependency on External Factors: Foreign currency defaults are often influenced by external economic conditions and international relations, making them harder to predict and manage.
  4. Credit Rating: A foreign currency default typically results in a significant downgrade in the country’s credit rating.
  5. Access to International Capital Markets: The country may lose access to international capital markets, making it harder to borrow in the future.

Local Currency Defaults

• Characteristics:
  1. Nature of Debt: Debt issued and owed in the country’s own currency.
  2. Reasons for Default: Although countries can theoretically print more of their own currency, defaults can still occur due to specific circumstances:
     1. Gold Standard: Historical limits on printing currency due to the need to back it with gold reserves.
     2. Shared Currency: Loss of control over currency printing in countries using a shared currency (e.g., Greece in the Eurozone).
     3. Economic Trade-offs: The deliberate choice to default rather than devalue the currency excessively to avoid hyperinflation and economic collapse.
  3. Market Perception: Local currency debt is often perceived as less risky than foreign currency debt because the country controls the currency in which the debt is denominated.
  4. Historical Examples: Local currency defaults are less common but have occurred under specific circumstances, such as during severe economic crises or when countries have lost control over their monetary policy. Notable defaults include Argentina (2002-2004), Madagascar (2002), and Russia (1998-1999).
  5. Magnitude: Russia’s default on $39 billion worth of ruble debt in 1998 and Brazil’s default on $62 billion of local currency debt in 1990 stand out as significant instances of local currency defaults .
• Causes:
  1. Monetary Policy: Mismanagement of monetary policy, leading to hyperinflation or severe devaluation of the local currency.
  2. Fiscal Imbalances: Persistent fiscal deficits and a high debt-to-GDP ratio can erode confidence in the government’s ability to manage its debt.
  3. Political Instability: Political turmoil can undermine the ability or willingness of a government to honor its debt commitments.
  4. Institutional Weaknesses: Weak financial institutions and lack of fiscal discipline can also contribute to the likelihood of defaulting on local currency debt.
• Implications and Challenges:
  1. Inflation Risk: Printing more local currency to meet debt obligations can lead to hyperinflation, eroding the value of the currency and harming the economy.
  2. Economic Trade-offs: Countries must balance the costs of defaulting versus the consequences of currency devaluation and inflation.
  3. Institutional Constraints: Some countries may face legal or institutional constraints that limit their ability to print money.
• Understanding the differences between foreign currency defaults and local currency defaults is crucial for assessing a country’s sovereign risk. While foreign currency defaults are driven by external debt obligations and lack of control over foreign currency, local currency defaults are influenced by economic policy decisions and constraints on currency printing. Both types of defaults have significant economic implications, requiring careful management and strategic decision-making by governments.

Consequences Of A Country’s Default

• When a government defaults on its financial obligations, the ramifications are significant and multifaceted, impacting both the domestic and international spheres. Historically, defaults have led to severe consequences, and while the nature of these repercussions has evolved over time, the gravity remains. Some of the consequences of a country’s default are as follows:
  1. Reputation Loss: A government that defaults acquires a negative reputation, labeled as a “deadbeat”. This tarnished image makes it challenging to secure financing in the future as lenders are wary of the risk involved. The difficulty in raising funds can hinder future economic growth and development efforts as access to international capital markets becomes restricted.
  2. Capital Market Turmoil: Sovereign default triggers turmoil in capital markets. Investors often withdraw from both equity and bond markets, fearing further losses. This withdrawal makes it more challenging for private enterprises within the defaulting country to raise funds for projects, stifling economic activity and investment.
  3. Real Output Decline: The uncertainty created by a sovereign default affects real investment and consumption. Businesses and consumers hold back on spending and investment, anticipating further economic instability. Typically, defaults lead to economic recessions, with real GDP dropping between 0.5% and 2%. The bulk of this decline occurs in the first year following the default but tends to be short-lived.
  4. Political Instability: Defaults can erode national confidence and lead to political instability. Historical examples include the rise of the Nazis following defaults in Europe during the 1930s. Political instability can lead to coups and changes in leadership, further exacerbating economic and social turmoil.
  5. Lower Ratings and Higher Long-Term Borrowing Costs: Defaults have long-term effects on a country’s sovereign ratings and borrowing costs. Defaulting countries often face higher borrowing costs, about 0.5% to 1% higher than non-defaulting countries. The increased costs persist for years, making it more expensive for the country to borrow and potentially leading to a cycle of borrowing at higher rates.
  6. Trade Retaliation: Sovereign default can lead to trade retaliation. Studies indicate a drop of 8% in bilateral trade following a default, with the effects lasting up to 15 years. Export-oriented industries suffer significantly, harming the overall trade balance and economic stability.
  7. Banking System Fragility: Sovereign default can make banking systems more fragile. The probability of a banking crisis increases significantly in countries that have defaulted. Fragile banking systems can lead to credit shortages and financial instability, further damaging the economy.
  8. Likelihood of Political Change: Defaults often lead to political change, as seen with sharp devaluations accompanying defaults. Studies show a significant increase in the probability of changes in top leadership and finance executives following defaults. Such political changes can lead to policy uncertainty and disrupt ongoing economic reforms and development plans.
• Overall, sovereign default has serious and long-lasting effects. Defaults usually lead to debt restructuring rather than total debt cancellation, with negotiations for extended time or reduced payments. The financial repercussions are severe, especially when defaults lead to banking

Measures Of Sovereign Default Risk

1. Sovereign ratings: Sovereign ratings are assessments provided by third-party agencies that evaluate the default risk of a country’s government. These ratings are critical because they influence investor perceptions and the interest rates that countries pay on their debt.
   • Historical Background and Evolution:
     1. Agencies: Agencies like Moody’s, Standard & Poor’s (S&P), and Fitch have a long history of assessing default risk, dating back to the early 20th century. Initially focused on corporate bonds, these agencies extended their expertise to sovereign bonds over time.
     2. Countries: The number of countries with sovereign ratings has grown significantly since the 1970s, with over a hundred countries rated by major agencies by 2022.
     3. Rating Scale: Ratings range from investment grade (e.g., AAA, AA) to speculative grade (e.g., BB, B, C), indicating the likelihood of default.
     4. Credit Watch and Outlook: Agencies also provide outlooks (positive, negative, stable) and place ratings on credit watch for potential upgrades or downgrades.
   • Local and Foreign Currency Ratings:
     1. Agencies typically provide two ratings for each country, one for local currency debt and another for foreign currency debt. Local currency ratings generally tend to be higher due to the government’s ability to print its own currency, though exceptions exist based on specific circumstances, such as monetary policy constraints.
     2. The difference between these ratings is influenced by a country’s monetary policy independence. Countries with floating exchange rates and deep domestic markets often have higher local currency ratings, while those with limited monetary policy control, such as those in a monetary union, see their ratings converge.
   • Consensus, Regional Biases and Variations Among Ratings:
     1. While there is often consensus among different ratings agencies on a country’s risk level, variations can occur due to differing assessments of political and economic risks, as well as potential home biases. Some critics argue that US-based agencies tend to overrate the US compared to other regions.
     2. One criticism of ratings agencies is that they may have regional biases, potentially underrating entire regions like Latin America and Africa. Ratings agencies defend this by pointing to historical default data, arguing that regions with frequent past defaults are rated more cautiously.
     3. S&P focuses primarily on the probability that a default will occur, without necessarily incorporating the severity of the default. Moody’s takes into account both the probability of default and the expected severity of the default, which is captured in the expected recovery rate.
2. Credit Default Swap (CDS) Spreads: CDS spreads reflect the cost of insuring against a sovereign default. Higher CDS spreads indicate a higher perceived risk of default. They are market-based measures providing real-time risk assessment. These spreads offer an immediate view of market sentiment and are influenced by a variety of factors including economic news, political events, and market liquidity.
3. Bond Yield Spreads Comparison: This measure compares the yield on a country’s bonds to a benchmark, typically U.S. Treasury bonds. Wider spreads indicate higher perceived risk. Market-based measure that reflects the additional return investors demand for taking on the higher risk associated with a particular country’s bonds. Bond yield spreads are sensitive to changes in both the issuing country’s economic outlook and global financial conditions.

Components Of A Sovereign Rating

• Sovereign ratings are determined based on various factors that encompass political, economic, and institutional variables Some of the main components considered are:

1. Political Risk:
   1. Stability and legitimacy of political institutions
   2. Popular participation in political processes
   3. Orderliness of leadership succession

• Sovereign ratings take into account a wide range of political, economic, and institutional factors to assess a country’s creditworthiness and risk of default. These ratings are crucial for investors and policymakers to make informed decisions. While there are some criticisms, such as possible biases and challenges in capturing short-term risks, sovereign ratings are still very important. They help provide a detailed picture of a country’s financial health, highlighting the need for thorough analysis and careful decision-making in financial markets.

Shortcomings Of Sovereign Rating Systems

• Despite the importance and overall track record of sovereign rating agencies, there are several criticisms and shortcomings associated with their methodologies and practices:

1. Timeliness and Responsiveness:
   1. Criticism: Ratings agencies often take too long to update their ratings, meaning that changes may come too late to protect investors from impending crises.
   2. Impact: Investors need timely assessments to accurately price sovereign bonds or set interest rates on sovereign loans. Delays in rating updates can result in significant financial losses for investors.
2. Upward Bias:
   1. Criticism: Ratings agencies have been accused of being overly optimistic in their assessments of both corporate and sovereign ratings. This is less justifiable for sovereign ratings since the revenues from providing these ratings are relatively small compared to the potential reputation loss from overrating.
   2. Impact: Overly positive ratings can mislead investors about the true risk, leading to underestimation of potential defaults and financial instability.
3. Herd Behavior:
   1. Criticism: When one rating agency adjusts a sovereign rating, others tend to follow suit, leading to herd behavior. This reduces the value of having multiple ratings agencies as their assessments become less independent.
   2. Impact: This behavior diminishes the reliability of ratings as diverse and independent assessments, potentially leading to synchronized misjudgments in the financial markets.
4. Vicious Cycle:
   1. Criticism: In times of market crises, ratings agencies are sometimes perceived as overreacting and lowering ratings excessively, which can exacerbate the crisis.
   2. Impact: Overly severe downgrades can create a negative feedback loop, worsening the financial situation and making recovery more difficult for the affected country.
5. Ratings Failures:
   1. Criticism: Frequent changes in ratings within a short period indicate failures in the initial rating assessments. This suggests that the ratings were inaccurate or not robust enough to begin with.
   2. Impact: Multiple ratings changes can undermine investor confidence and indicate fundamental flaws in the ratings process.
6. Information Problems:
   1. Criticism: Ratings agencies rely heavily on data provided by the governments themselves, which can vary widely in quality and may be selectively disclosed to hide negative information.
   2. Impact: This reliance can lead to inaccuracies in ratings, as agencies may not have a complete or accurate picture of the country’s financial health.
7. Limited Resources:
   1. Criticism: The revenues generated from sovereign ratings are limited, restricting the agencies’ ability to hire sufficient analysts. Analysts are often spread thin, covering multiple low-profile countries.
   2. Impact: Overworked analysts may rely on common information and display herd behavior rather than conducting thorough, independent research, reducing the quality and accuracy of ratings.
8. Revenue Bias:
   1. Criticism: Revenues from sovereign ratings, either directly from issuers or indirectly from related businesses, can create a bias towards favorable ratings to maintain these income streams.
   2. Impact: This potential conflict of interest can lead to less stringent ratings, as agencies may be hesitant to downgrade sovereigns and subsequently impact related sub-sovereign entities.
9. Other Incentive Problems:
   1. Criticism: Analysts may have career incentives, or the agencies may have other business interests that influence their ratings.
   2. Impact: These conflicts of interest can undermine the objectivity and reliability of the ratings provided.

• The shortcomings of sovereign rating systems highlight the complexity and challenges in accurately assessing sovereign risk. While these ratings play a crucial role in financial markets, the above-mentioned limitations underscore the need for continuous improvement in methodologies and practices to ensure more accurate and reliable risk assessments.

Comparison Of Methods

• When evaluating sovereign default risk, analysts and investors use a variety of measures, including credit ratings, market-based credit default spreads, and Credit Default Swap (CDS) spreads. Each method has its strengths and weaknesses, offering different insights into a country’s default risk.

1. 1. Credit RatingsOverview:
      1. Provided by: Rating agencies like Moody’s, S&P, and Fitch.
      2. Nature: Assessments of a country’s creditworthiness, generally updated periodically.
      3. Components: Include evaluations of political risk, economic structure, fiscal flexibility, and more.

      Strengths:

      1. Comprehensive Analysis: Incorporate a wide range of factors including economic, political, and institutional variables.
      2. Standardization: Provide a standardized measure that is widely understood and used in
         financial markets.
      3. Long-term Perspective: Offer a long-term view of creditworthiness, less susceptible to short-term market fluctuations.

      Weaknesses:

      1. Timeliness: Often criticized for being slow to update, potentially leaving investors unprotected in a rapidly changing environment.
      2. Herd Behavior: Ratings changes by one agency can lead to similar changes by others, reducing independent assessments.
      3. Potential Biases: Accusations of upward bias and regional biases, and conflicts of interest.
   2. Market Based Credit Default SpreadsOverview:
      1. Provided by: Derived from the difference between the interest rate on a country’s bonds and a risk-free benchmark (typically U.S. Treasury bonds).
      2. Nature: Reflects the market’s real-time assessment of default risk.

      Strengths:

      1. Real-time Updates: Provides continuous, up-to-date measures of risk, adjusting quickly to new information.
      2. Granular Differentiation: Offers finer distinctions between the default risks of different countries compared to rating agencies. For example, in July 2022, both Colombia and Indonesia had the same Moody’s rating (Baa2), but the market demanded a higher rate of return for Colombian bonds, reflecting higher perceived risk.
      3. Market-Driven: Reflects the collective judgment of market participants, potentially incorporating a wide range of information.

      Weaknesses

      1. Volatility: Default spreads are volatile and can be influenced by factors unrelated to default risk, such as investor demand and changes in liquidity conditions.
      2. Comparing Local Currency Bonds: Local currency bonds do not have a risk-free security for comparison, making it impractical to compare them across countries due to differences in expected inflation rather than true risk.
      3. Liquidity Issues: Changes in spreads can be driven by liquidity conditions rather than actual changes in default risk.

      Additional Points:

      1. Correlation with Ratings and Default Risk: Default spreads are positively correlated with ratings and default risk. Low-rated sovereign bonds tend to trade at higher yields and are more likely to default.
      2. Leading Indicators: Default spreads often widen before a rating downgrade and narrow before a rating upgrade, providing early signals of changing risk.
      3. Informational Content: Despite their lag time, rating changes provide significant information to the market. Ratings agencies use market data for their decisions, and the market reacts to rating changes, making both ratings and default spreads useful for assessing sovereign default risk.
   3. Credit Default Swap (CDS) SpreadsOverview
      1. Provided by: The price of CDS contracts, which offer protection against default on specific bonds.
      2. Nature: Market-based, reflects the cost of insuring against a sovereign default.

      Strengths:

      1. Timeliness: Like bond spreads, CDS spreads adjust quickly to new information, providing real-time risk assessments.
      2. Advance Warning: Often provides early signals of changing default risk, ahead of bond spreads and credit ratings. For instance, during the 2009-2010 period, CDS spreads for several European sovereigns, including Greece, changed much more frequently than sovereign ratings.
      3. Market Sentiment: Reflects market sentiment and perceived risk, incorporating the latest economic and political developments.
      4. Economic Policy Uncertainty: CDS spreads increase with heightened economic policy uncertainty and track with currency depreciation, offering insights into the interplay between policy uncertainty, currency risk, and default risk.
      5. Clustering Effect: The CDS market exhibits a clustering effect where CDS prices across groups of countries move cohesively, indicating systemic factors at play.

      Weaknesses:

      1. Counterparty Risk: The effectiveness of CDS as a risk measure depends on the creditworthiness of the CDS seller.
      2. Liquidity Concerns: The CDS market can be narrow, with prices influenced by liquidity and the actions of a few major players.
      3. Volatility: Similar to bond spreads, CDS prices can be very volatile and influenced by factors beyond default risk.
      4. Complexity: CDS spreads reflect a range of risks including credit, market, and liquidity risks, which can sometimes lead to overestimation of default risks.

Comparative Analysis

1. 1. Timeliness and Responsiveness:
      1. Credit Ratings: Updated periodically, often lag behind market events.
      2. Bond Spreads: Provide real-time updates, reflecting current market sentiment.
      3. CDS Spreads: Also provide real-time updates and often lead changes in bond yields and ratings, reflecting fundamental changes immediately.
   2. Predictive Power:
      1. Credit Ratings: Offer a comprehensive but sometimes delayed assessment of default risk.
      2. Bond Spreads: Correlated with ratings and default risk, but can be affected by market liquidity and sentiment.
      3. CDS Spreads: Often provide early warnings of default risk changes and are seen as strong predictors of default events, often preceding changes in sovereign bond yields and ratings.
   3. Market Sensitivity:
      1. Credit Ratings: Less sensitive to short-term market movements, providing a stable long-term view.
      2. Bond Spreads: Highly sensitive to market conditions and investor sentiment, providing immediate feedback.
      3. CDS Spreads: Equally sensitive to market conditions, offering real-time insights but with added counterparty risk concerns.
   4. Information Content:
      1. Credit Ratings: Incorporate a broad range of economic, political, and institutional factors.
      2. Bond Spreads: Reflect immediate market conditions and investor expectations.
      3. CDS Spreads: Combine market sentiment with specific protection costs against default, offering detailed risk assessments and insights into economic policy uncertainty and clustering effects.

• Credit ratings, market-based credit default spreads, and CDS spreads each provide valuable insights into sovereign default risk, but they serve different roles and have distinct strengths and weaknesses. Credit ratings offer a comprehensive and standardized assessment, though they may lag in timeliness. Market-based credit default spreads and CDS spreads provide real-time, dynamic measures of risk, with CDS spreads often leading in predicting changes and offering additional insights into economic policy uncertainty and systemic risks. However, these market-based measures can be volatile and influenced by factors beyond default risk. Effective risk assessment typically involves considering all these measures to gain a well-rounded understanding of sovereign default risk.
