Open research questions in Credit Risk and Financial Regulations

64 unresolved questions extracted from the limitations and future-work sections of 776 Credit Risk and Financial Regulations papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • Many traditional credit measures are more informative about current rather than future credit risk. Market-based measures of credit risk, like credit spreads or implied volatilities, are forward-looking but contain other confounding influences. Prior work has not fully explored the information content of earnings calls for credit risk forecasting.

    Credit information in earnings calls · 2026 · DOI

  • The presence of asymmetric funding costs, defaults, and wrong way risk makes the valuation problem complex. The non-linear Cauchy problem is difficult to solve. The paper needs to provide an analytical formula for the valuation of a vulnerable equity forward.

    Analytical Valuation of Vulnerable Derivative Claims with Bilateral Cash Flows under Credit, Funding and Wrong Way Risk · 2026 · DOI

  • The paper identifies a gap in the existing literature on the valuation of vulnerable derivative claims. The paper notes that existing models do not account for the presence of asymmetric funding costs, defaults, and wrong way risk.

    Analytical Valuation of Vulnerable Derivative Claims with Bilateral Cash Flows under Credit, Funding and Wrong Way Risk · 2026 · DOI

  • There is an absence of economic rationale as to how points are applied in individual cases. There is very little formal analysis of the policies that lenders use to determine the points charged to borrowers.

    Discount Points, Effective Yields and Mortgage Prepayments · 1987 · DOI

  • The paper identifies a gap in the understanding of the relationship between vertical integration and systematic risk. Prior studies have not differentiated between types of mergers.

    Vertical Integration and Risk Reduction · 1987 · DOI

  • The study does not consider other types of derivatives. The numerical experiments are limited to a European swaption under the SABR model. The impact of a SIC default is modeled as a discrete jump, which may not capture all possible scenarios.

    Impact of Systemically Important Counterparty Default on Counterparty Credit Risk · 2026 · DOI

  • The ISDA Standard Initial Margin Model does not accurately model the systemic impact of a SIC default. There is a need for more accurate CCR models that incorporate the impact of a SIC default.

    Impact of Systemically Important Counterparty Default on Counterparty Credit Risk · 2026 · DOI

  • Exclusions encompassed firms in the over-the-counter (OTC) base market, financial institutions, entities with negative book value, those experiencing extended trading halts, and firms with insufficient data availability.

    Pricing the Default Risk Factor in Short-Term Debt: A Compound Option Approach in the Iranian Capital Market · 2026 · DOI

  • The absence of a rigorous Crypto XVA framework that addresses the unique risk characteristics of blockchain-based financial instruments. The lack of a systematic approach to valuation adjustments in digital asset markets. The need for a unified framework for measuring valuation adjustments and risk surfaces specific to digital-asset markets.

    Crypto XVA - a framework for valuation adjustments in digital asset markets · 2026 · DOI

  • 2 The Sparse Data Problem A rigorous objection to the framework is that crypto risk event data is sparse. We propose a hybrid calibration approach that draws on three complementary methods: deterministic inputs for well-documented parameters, Bayesian inference for parameters with limited data but informative priors, and Monte Carlo simulation for tail risk and reflexive dynamics. Stress-period data is sparse by construction.

    Crypto XVA - a framework for valuation adjustments in digital asset markets · 2026 · DOI

  • The two-period model is intentionally stylized and lacks explicit price formation in secondary markets. The meta-analysis treats the eleven in-sample episodes as conditionally independent draws, which is an idealization. The LP-IV companion is honestly weak-identified, and the AR confidence sets are valid but informative at only six of thirteen horizons.

    The K-A-T Framework: A Unified Framework for Macro-Financial Propagation Through Funding Constraints, Networks, and Policy Backstops · 2026 · DOI

  • The lack of a unified framework for macro-financial propagation. The lack of a comprehensive analysis of the dynamics of stress in the financial system. The need for a new perspective on the role of policy backstops in mitigating the effects of funding shocks.

    The K-A-T Framework: A Unified Framework for Macro-Financial Propagation Through Funding Constraints, Networks, and Policy Backstops · 2026 · DOI

  • A comprehensive empirical research design is required for backtesting, - The study suggests conducting a backtesting exercise to validate the proposed framework.

    A closer look at the probability of default taking into account the current regulatory considerations · 2026 · DOI

  • The existing PD models rely on restrictive assumptions, - The logistic regression models may not account for complex structures in firm-specific risk drivers.

    A closer look at the probability of default taking into account the current regulatory considerations · 2026 · DOI

  • There is a lack of research on the relationship between CDS premiums and money market funds. Prior studies have not examined the long-term relationship between the two variables.

    Para Piyasası Fonları İle Kredi Temerrüt Swapları (CDS) Arasındaki İlişki: Türkiye Örneği · 2026 · DOI

  • The existing literature does not provide a comprehensive understanding of the time-varying causal relationships between credit default swaps, effective funding rate, exchange rate-protected deposit scheme, and stock market returns in Turkiye.

    Time-Dependent Causal Relationships Between Credit Default Swaps, Effective Funding Rate, Exchange Rate-Protected Deposit Scheme, and Stock Market Returns: Evidence from Turkiye · 2026 · DOI

  • The lack of incorporation of systemic risk into derivative pricing frameworks. The need for more robust tail risk measures. The gap in the literature on the application of machine-learning approaches to estimate tail-risk components.

    Stress-consistent macroprudential overlay for derivative pricing · 2026 · DOI

  • The gap in existing research is the lack of consideration of dependence uncertainty in systemic risk measurement. The paper addresses this gap by employing factor models to represent partial information on companies' risk exposures.

    Static marginal expected shortfall: Systemic risk measurement under dependence uncertainty · 2026 · DOI

  • To verify the identification of the H^2 class as a candidate early warning indicator from data. To apply the cohomological approach to analyze systemic risk in other contexts.

    Systemic Risk as $H^2$: Cohomological Stress Testing, the Unhedgeable Residual, and Why the 2008 Crisis Was a Topological Event · 2026 · DOI

  • The current stress testing methods are insufficient as they only compute the sum of bilateral losses across institutions. The H^2 gap refers to the part of systemic risk that lives not in individual institutions' portfolios but in the interaction between those portfolios.

    Systemic Risk as $H^2$: Cohomological Stress Testing, the Unhedgeable Residual, and Why the 2008 Crisis Was a Topological Event · 2026 · DOI

  • Future studies could evaluate the effectiveness of bond portfolio immunization during other time periods or using different methodologies. Future research could also explore the application of the study's findings to other areas of institutional investment management.

    AN EMPIRICAL STUDY OF BOND PORTFOLIO IMMUNIZATION EFFECTIVENESS DURING 2008 GLOBAL FINANCIAL CRISIS · 2026 · DOI

  • Existing literature on bond immunization largely falls into two categories: theoretical extensions of Redington's model under stochastic interest rate assumptions, and empirical tests conducted during ordinary, non-crisis market conditions using real-world bond portfolios. Few studies isolate the pure interest-rate-risk performance of Redington immunization specifically across the 2008 GFC window using a controlled, default-free instrument.

    AN EMPIRICAL STUDY OF BOND PORTFOLIO IMMUNIZATION EFFECTIVENESS DURING 2008 GLOBAL FINANCIAL CRISIS · 2026 · DOI

  • Financial-literacy programmes should increase public awareness about credit ratings and their importance in investment planning. Greater cooperation among financial institutions, regulatory authorities, and credit rating agencies should be encouraged. Credit-rating analysts should receive continuous professional training to maintain high standards of credit evaluation.

    A Study on the Role of Credit Rating Agencies in India · 2026 · DOI

  • The study identifies the need for regulatory oversight and technological improvements in the credit rating industry. The study highlights the importance of credit rating agencies in India's financial system.

    A Study on the Role of Credit Rating Agencies in India · 2026 · DOI

  • Future research can focus on empirical testing of the theoretical framework. Future research can explore the application of the framework to other areas of finance.

    Delegated Portfolio Management With Random Default · 2026 · DOI
