The Pricing of Geopolitical Tensions over a Century
Andrei S. Gonçalves, Alessandro Melone, Andrea Ricciardi
News article: "Exploring a century of global conflicts and their impact on financial assets"
Executive Summary
This study explores the role of geopolitical tensions in asset pricing over the past century. The authors propose a novel decomposition of geopolitical risk into two distinct components: Geopolitical Threats (GPT), which represent forward-looking concerns about potential adverse geopolitical events, and Geopolitical Acts (GPA), which capture the actual realization of such events, such as the outbreak of wars. Drawing on the Caldara and Iacoviello (2022) geopolitical risk index, the paper constructs and analyzes these components to investigate their distinct effects on financial markets and economic outcomes.
The analysis reveals that GPT, not GPA, plays a central role in shaping investors’ perception of risk. GPT rises prior to major geopolitical conflicts, reflecting investor fear and anticipation, while GPA merely reacts to realized shocks. Unlike GPA, GPT is consistently priced in asset markets. It correlates with institutional risk perceptions, predicts long-term consumption disasters, and explains both cross-sectional and time-series variation in expected returns. These features are particularly salient for long-term investors with Epstein-Zin preferences, who are sensitive to low-probability, high-impact events.
The empirical scope of the paper spans a wide range of asset classes, including U.S. equities, equity anomalies, and global stock and bond portfolios. Portfolios with high exposure to GPT earn significantly higher risk premia, with estimates as high as 4.17% per annum in U.S. equities. These premia are robust to the inclusion of standard asset pricing factors, including the CAPM, ICAPM, Fama-French factors and q-factors, and remain strong after controlling for other measures of uncertainty, such as economic and trade policy uncertainty, expected market volatility and war discourse.
In the time series, GPT significantly predicts equity risk premia over 3- and 5-year horizons, emphasizing its relevance for long-horizon asset allocation. The predictability is particularly strong during periods of heightened geopolitical attention, proxied by lagged levels of geopolitical risk. The evidence that GPT forecasts bond risk premia is limited.
The paper also documents real economic effects of geopolitical threats. Increases in GPT are followed by significant declines in corporate investment, likely reflecting a perceived increase in investment risk and political instability. No similar pattern is observed in response to GPA.
These findings carry important implications for both researchers and policymakers. From an academic perspective, the results underscore the need for asset pricing models to distinguish between anticipatory threats and realized events, as only the former appear to carry systematic risk. For practitioners and policymakers, monitoring forward-looking measures such as GPT can offer valuable insights into market vulnerability during periods of geopolitical stress and may inform both investment strategies and macroeconomic policy decisions.

The Disclosure of Risk Appetite
Don Pagach
Executive Summary
This paper examines the economic relevance of publicly disclosed corporate risk appetite following the 2022 revision of the Dutch Corporate Governance Code, which mandates disclosure of risk appetite across strategic, operational and financial objectives. While enterprise risk management (ERM) frameworks emphasize risk appetite as a core governance tool, little empirical evidence exists on how such disclosures are interpreted by capital markets when they become mandatory and publicly observable. This study addresses that gap by analyzing whether disclosed risk appetite levels and the specificity of those disclosures are associated with firm performance, risk and valuation.
Grounded in governance and risk management theory, particularly Stulz (2016), the paper conceptualizes risk appetite not as a signal of future performance, but as a mechanism intended to constrain managerial risk taking and align decisions with strategy. Under this governance view, the numerical level of disclosed risk appetite should not necessarily predict outcomes. Instead, the credibility of the disclosure, reflected in how clearly and precisely risk appetite is articulated, should matter more to external stakeholders.
The empirical analysis used hand collected risk appetite disclosures from 2023 annual reports of Dutch non financial firms subject to the revised Code. The final sample included 64 firms with complete disclosures and financial data. Risk appetite was coded separately for strategic, operational and financial dimensions using a common five point ordinal scale. Importantly, the study introduced a novel measure of disclosure specificity, classifying disclosures as narrative, range based or point based, capturing the extent to which firms impose explicit and interpretable constraints on risk taking.
Results show substantial heterogeneity in both the level and form of risk appetite disclosures. Firms generally report higher tolerance for strategic risk than for operational or financial risk, consistent with disciplined risk governance. However, across a broad set of outcomes, including accounting performance (ROA, ROE), stock returns, equity risk and valuation, the numerical level of disclosed risk appetite is not systematically associated with firm outcomes. These findings support the hypothesis that risk appetite levels are not priced by markets.
In contrast, disclosure specificity is positively and robustly associated with firm valuation. Firms that articulate risk appetite using ranges or point estimates exhibit higher market to book ratios than firms relying on purely narrative statements. This association holds even though specificity is not mechanically related to the level of risk appetite, indicating that it captures a distinct governance dimension. Interaction tests provide limited evidence that specificity conditions the effect of risk appetite levels, reinforcing the conclusion that markets respond primarily to how risk appetite is disclosed, not what level is chosen.
The study contributes to the literature on risk disclosure, ERM and corporate governance by demonstrating that mandated risk appetite disclosures derive their economic relevance from disclosure design rather than disclosure content alone. Policy implications are clear: regulators and standard setters seeking to improve governance transparency should focus not only on requiring disclosure, but on encouraging specificity and credibility. For boards, the findings suggest that precise risk appetite disclosures can enhance governance credibility and market valuation, while vague statements may offer little benefit beyond compliance.
