Assessing the Impact of Derivatives on the 2008 Financial Crisis and the Effectiveness of Subsequent Regulatory Reforms

The 2008 financial crisis was a global financial catastrophe that reflected the misuse of financial derivatives in financial markets, such as credit default swaps, asset-backed securities and collateralized debt obligations, exposing significant weaknesses in the global financial system. These financial instruments were designed to hedge against debt risk, but their lack of transparency and massive misuse ultimately led to the accumulation of systemic risk that accelerated the financial crisis. Since then, regulatory authorities around the world have realized the necessity for stronger regulatory frameworks, and a series of significant reforms have been implemented, such as the Dodd-Frank Wall Street Reform and Consumer Protection Act in the United States, the European Market Infrastructure Regulation in the European Union, and the Basel III international regulatory framework, with the objectives of increasing transparency in financial markets and improving the risk management measures of financial institutions. This paper will explore the role of derivatives in the 2008 financial crisis and examine the effectiveness of these regulatory measures introduced after the crisis in enhancing stability of financial system.

Parent-Only Balance Sheet Information and Credit Risk Assessments

SYNOPSIS General-purpose financial statements prepared under GAAP are for a consolidated reporting entity—a collection of legal entities that includes the parent and any subsidiaries it controls. This reporting model results in a loss of information about the individual legal entities within the consolidated reporting entity. Our study examines the role of parent-only balance sheet information in assessing the credit risk of the parent when it is a bank holding company. We obtain evidence from three trading platforms: credit default swaps (CDS), outstanding bonds, and new bonds. We find that parent-only leverage is useful for debtholders to assess the parent’s credit risk even after considering consolidated leverage. Moreover, in CDS markets, parent-only leverage is more useful for firms without downstream guarantee than for firms with guarantee and is less useful for firms with a stronger internal capital market. Our study raises the awareness of parent-only financial information for credit risk assessments. Data Availability: All data are available from the identified public sources.

Forecasting sovereign CDS spreads with a regime‐switching combination method

AbstractWith the growing importance of the sovereign credit default swap (CDS) market, accurate forecasting of sovereign CDS spreads has gained significant attention. In view of the complex volatility in the series of sovereign CDS spreads, this study presents a novel combination forecasting framework, which introduces time‐varying weights to effectively combine diverse individual models. To identify optimal subsets of models, a mutual information approach is employed, while the regime‐switching method is utilized to integrate the selected models. The proposed method's efficacy is validated using data from 65 countries. Empirical findings underscore the superiority of the proposed approach over benchmark models in terms of both horizontal and directional prediction accuracy, particularly when the sovereign CDS data exhibits a balanced distribution between high and low volatility regimes.

The real effect of CDS trading: Evidence from corporate employment

AbstractThis paper examines whether the inception of credit default swaps (CDS) trading curbs corporate employment. We show that firms with CDS trading have significantly lower employment growth. Our baseline results are robust to alternative measures of corporate employment growth, various approaches that mitigate endogeneity concerns due to omitted variables and reverse causality, and additional control variables. The decrease in firms' employment growth after CDS trading is more pronounced in firms with larger financial constraints and lower CEO risk‐taking. In addition, we find that the inception of CDS trading affects employment growth through the financial distress channel. Further analysis finds that the inception of CDS trading could mitigate the labor over‐investment problem, stimulating employment efficiency. Our evidence suggests that corporate employment growth is reduced after the initiation of CDS trading due to the heightened cost of defaults.

Sovereign Credit Risk in Saudi Arabia, Morocco and Egypt

The purpose of this paper is to assess and predict sovereign credit risk for Egypt, Morroco and Saudi Arabia using credit default swap (CDS) spreads obtained from the DataStream database for the period from 2009 to 2022. Our approach consists of generating the implied default probability and the corresponding credit rating in order to estimate the term structure of the implied default probability using the Nelson–Siegel model. In order to validate the prediction from the probability term structure, we calculate the transition matrices based on the implied rating using the homogeneous Markov model. The main results show that, overall, the probabilities of defaulting in the long term are higher than those in the short term, which implies that the future outlook is more pessimistic given the events that occurred during the study period. Egypt seems to be the country with the most fragile economy, especially after 2009, likely because of the political events that marked the country at that time. The economies of Morocco and Saudi Arabia are more resilient in terms of both default probability and credit rating. These findings can help policymakers develop targeted strategies to mitigate economic risks and enhance stability, and they provide investors with valuable insights for managing long-term investment risks in these countries.

Modeling Risk Sharing and Impact on Systemic Risk

This paper develops a simplified agent-based model to investigate the dynamics of risk transfer and its implications for systemic risk within financial networks, focusing specifically on credit default swaps (CDSs) as instruments of risk allocation among banks and firms. Unlike broader models that incorporate multiple types of economic agents, our approach explicitly targets the interactions between banks and firms across three markets: credit, interbank loans, and CDSs. This model diverges from the frameworks established by prior researchers by simplifying the agent structure, which allows for more focused calibration to empirical data—specifically, a sample of Swiss banks—and enhances interpretability for regulatory use. Our analysis centers around two control variables, CDSc and CDSn, which control the likelihood of institutions participating in covered and naked CDS transactions, respectively. This approach allows us to explore the network’s behavior under varying levels of interconnectedness and differing magnitudes of deposit shocks. Our results indicate that the network can withstand minor shocks, but higher levels of CDS engagement significantly increase variance and kurtosis in equity returns, signaling heightened instability. This effect is amplified during severe shocks, suggesting that CDSs, instead of mitigating risk, propagate systemic risk, particularly in highly interconnected networks. These findings underscore the need for regulatory oversight to manage risk concentration and ensure financial stability.

Cross-border sovereign risk transmission in BRICIT Nations: Unveiling asymmetries and the role of country risk premiums

This research highlights the asymmetric interdependence structure among the sovereign risks of Brazil, Russia, India, China, Indonesia, and Türkiye (BRICIT) nations, challenging the traditional view that bilateral trade is the main channel for cross-border spillover effects. Despite their dependence on Russian crude oil imports for energy, the BRICIT nations show no significant sovereign risk interdependence with Russia. The study finds that Indonesia's credit default swap (CDS) has the highest level of interdependence with other nations. Further exploration of alternative transmission channels necessitates an examination of the country risk premium, revealing Türkiye as the most vulnerable nation due to its negative association with the CDS of other countries, particularly India. By contrast, India is identified as a preferred investment destination, thanks to its lower uncertainty and strong GDP growth over the past decade. Additionally, the research underscores China's economic influence, demonstrated by its positive association with all other BRICIT nations. This suggests that despite the high sovereign risk associated with China, investors do not view other emerging markets as viable, lower-risk alternatives. The perceived risk related to China appears to extend beyond its borders, impacting the sovereign risk profiles of other emerging economies.

Sovereign momentum currency returns

We study the relationship between cross-sectional sovereign credit risk and currency spot prices. We find that past (up to 12-month average) sovereign credit risk, measured by sovereign credit default swap (CDS) spreads, predict future currency spot returns. In particular, we document a significant cross-sectional currency portfolio spread in excess of the risk-free rate of return (up to 9.6% p.a.) between the highest and the lowest quintile sovereign CDS spreads. Overall, our results indicate that sovereign credit risk is systematically important for currency returns. Moreover, the level of sovereign credit risk has a persistent effect on currency returns which is consistent with a sovereign momentum effect.

Effects of Türkiye’s Credit Rantings and Credit Default Swaps (CDS) on BIST ALL

In the study, the relationship between Turkey's Credit Default Swaps (CDS) premiums and credit ratings of Standard and Poor's (S&P), Moody's Investors Service (Moody's) and Fitch Ratings (CRA) and the BIST ALL index listed in Borsa Istanbul and The aim is to observe their effects on each other. The universe of the study; consists of 3956 daily Turkey CDS credit risk premiums and BIST ALL data and 93 credit ratings given by CRAs in the period 2009:1–2024:4. The effect of the increase or decrease in CDS and credit scores on the closing values of the BIST ALL index was analysed with Johansen cointegration and Granger causality tests. Findings obtained in the study; Increasing the credit rating and outlook of CRAs causes an increase in BIST ALL closing values in the short term. The change in Türkiye CDS premiums triggers changes in BIST ALL closing values in the short and long term. Finally, the study concluded that the change in CDS premiums has a negative effect on BIST ALL, while the increase in credit score and outlook has a positive effect on BIST ALL.

Contagion and interdependencies between BRICS-plus Countries on the Markets of Commodities and Derivative Financial Instruments

Purpose: This study was started on the main macroeconomic data (2010-2019), coming from the countries of the BRICS-plus group. While a significant contribution of these emerging economies to global economic output has generally been observed, this has also been accompanied by persistent domestic imbalance. Design/Methodology/Approach: Regarding the model, we state and contextualize the (long-term) risk co-incidence of the set of macroeconomic variables for this coalition of countries. Particular attention was paid to a valuation, description and forecasting model based on the calculation of the Dynamic Conditional Correlation (DCC) in a Generalized AutoRegressive Conditional Heteroscedasticity (GARCH) process on the time series of credit default swaps (CDS). Findings: The empirical analysis and calculations carried out have verified the significance of the parameters and confirmed the conditional dynamic correlation between the economies of the Brics “expanded”, especially in the presence of shocks, which also involve mutual contagion (temporary increase in DCC) and even interdependence (increasing DCC leads to new, less unstable levels). Implications/Originality/Value: The research offers a look at the most current trends in terms of international economic balances and the entire global system, focusing on commodity markets, financial derivatives and the impacts of trade at the dawn of the new BRICS-plus coalition.

Policy uncertainty, bad news disclosure, and stock price crash risk

This paper documents that economic policy uncertainty reduces future stock price crash risk by increasing firms’ disclosure of bad news. Our tests show that firms release more bad news during periods of high policy uncertainty – they use more conservatism accounting, exhibit stronger future earnings response coefficients, use more negative tones in their financial reports, and have managers that express more negative sentiment in earnings conference calls than during periods of low policy uncertainty. Additional analyses show that the negative relation between EPU and future stock price crash risk is more pronounced among firms with more short-sale constraints, with no actively traded credit default swap contracts, with lower options-implied negative skewness, or with higher firm-level political risks. The results from regressions adopting the instrumental variable approach and from a quasi-natural experiment suggest that the negative relation observed between policy uncertainty and stock price crash risk is unlikely to be driven by potential endogeneity.

European Financial Markets Integration and the Politics of Credit Rating Agencies: An Econometric Approach to Study Microeconomic Dynamics and Sustainability

Abstract On sovereign credit default swaps markets, contagion serves as a sobering reminder of the interconnectedness of global financial systems. Like ripples in a pond, the impact of sovereign default or downgrades can cascade across borders, highlighting the intricate web of dependencies among nations. Utilizing sovereign CDS spreads between 2006-2020 on local European markets, the study employs an event study methodology to assess the effects of rating changes on CDS spreads, focusing on negative events such as sovereign rating downgrades. The findings reveal that negative events have a greater impact on the CDS market than positive events, abnormal returns are higher during economic crises, and states with public debt exceeding the Maastricht criteria experience higher abnormal returns. These results suggest that investors are sensitive to adverse news and risk factors, see opportunities for profit during economic turmoil, and closely monitor fiscal sustainability metrics. Understanding and managing contagion risk in these markets requires not only vigilance but also cooperation and coordination among policymakers and market participants.

Credit default swap spreads modeling and forecasting with a stochastic square-root three-factor model

In this study, we consider the CIR3 model, a three-factor stochastic model with correlated trends and volatilities for modeling and forecasting credit default swap (CDS) spreads. After recalling existence and uniqueness results, together with a generalized Feller condition to ensure positivity, we use a Lamperti-type transform to rewrite our SDEs system in a form in which the stochastic part of the leading process is uncorrelated with those of its mean and volatility processes. Finally, we calibrate the model through the estimating function approach for ergodic diffusions and simulate the CDS prices by discretizing our (transformed) system. These findings contribute to a deeper understanding of stochastic models with correlated trends and volatilities, with applications in pricing, trading and risk assessment.

Strict certainty preference in the predictive brain: a new perspective on financial innovations and their role in the real economy

The dominant paradigm in neuroscience considers the brain to be a prediction engine. The brain generates predictions first, which are then contrasted with information to generate error signals. Finite brain resources are subsequently spent in selectively processing the error signals based on their relative value with higher value signals getting a priority. In this way, the brain can be thought of as optimizing on its own internal resources before seeking to optimize on the resources available in the external world. We show that such considerations change the cost–benefit calculations of certain vs uncertain outcomes in the brain, giving rise to, what can be termed as, a strict certainty preference. A new perspective on prominent financial innovations (such as securitization, interest rate swaps, and credit default swaps) emerges, with a dark side that potentially leads to a misallocation of resources towards low NPV projects.

Beyond borders: Assessing the influence of Geopolitical tensions on sovereign risk dynamics

We assess the impact of geopolitical risk and world uncertainty on the sovereign debt risk of 26 European Economies during the period 1984–2022, through the implementation of OLS-Fixed Effects regressions and the Generalized Method of Moments (GMM). We find that geopolitical tensions and global uncertainty in border countries contribute to the rise of European country's sovereign risk as measured by 5- and 10-year Credit Default Swaps (CDS) and bond returns. Moreover, this interconnection is more pronounced during turbulent times such as the subprime crisis. Lastly, we found that geopolitical tensions in other country’ groups such as South America and Asia have a significant impact on the government risks of European countries.

Regulation and the demand for credit default swaps in experimental bond markets

Credit default swaps (CDS) played an important role in the financial crisis of 2008 leading to calls for regulation. Here, we seek to understand the impact of a CDS regulation that restricts the possibility to hold naked CDS. We use a controlled laboratory experiment analyzing CDS pricing in a bond market subject to default risk. Our results show that the regulation achieves the goal of increasing the use of CDS for hedging purposes while reducing the use of CDS for speculation. This success does not come at the expense of lower initial public offering (IPO) prices for the bonds or worse pricing of bonds or CDS in the secondary market.

Volatility Spillovers among Sovereign Credit Default Swaps of Emerging Economies and Their Determinants

This paper aims to investigate the volatility spillovers among selected emerging economies’ sovereign credit default swaps (SCDSs), including those of Saudi Arabia, Russia, China, Indonesia, South Africa, Brazil, Mexico, and Turkey. Using data from January 2010 to July 2023, we apply the time-domain and the frequency-domain connectedness approaches.Empirical results show that (i) Indonesia, followed by China and Mexico, are the main transmitters of sovereign credit risk volatility. (ii) Among global factors, the volatility index (VIX), economic policy uncertainty (EPU), and global political risk (GPR) positively impacted spillover on lower and higher quantiles. The results offer critical insights for international investors, policymakers, and researchers, emphasizing the importance of risk-aware investment strategies and cautious policy formulation in the context of financial crises and political events.
