This paper presents a new model for pricing over the counter (OTC) derivatives subject to collateralization. It allows for collateral posting adhering to bankruptcy laws. As such, the model can back out the market price of a collateralized contract. This framework is very useful for valuing outstanding derivatives.
Using a unique dataset, the author found empirical evidence that credit risk alone is not overly important in determining credit-related spreads. Only accounting for both collateral arrangement and credit risk can sufficiently explain unsecured credit costs. This finding suggests that failure to properly account for collateralization may result in significant mispricing of derivatives. The author also empirically gauges the impact of collateral agreements on risk measurements. The findings indicate that there are important interactions between market and credit risk.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This paper presents a new model for pricing over-the-counter (OTC) derivatives subject to collateralization, considering collateral posting adhering to bankruptcy laws. The model aims to accurately value outstanding derivatives by accounting for both credit risk and collateral arrangements. It seeks to demonstrate that failure to appropriately account for collateralization can lead to significant mispricing of derivatives.
- The impact of collateralization on derivatives pricing
- The relationship between collateralization and credit risk
- The interaction between collateralization, credit risk, and market risk
- Empirical evidence using a proprietary dataset from an investment bank
- The development of a model that characterizes the collateral process directly
Zusammenfassung der Kapitel (Chapter Summaries)
- The Introduction section outlines the significance of collateralization in the financial system and highlights the gap in existing research on its effects on valuation and risk. It discusses the limitations of previous models that address collateralization and introduces the novel model presented in this paper.
- The "Pricing Collateralized Financial Derivatives" chapter presents a new model for pricing collateralized derivatives, which accounts for collateral posting aligned with bankruptcy laws. It discusses the legal framework of collateral arrangements and the various types of collateralization: partial, over, and full. The chapter also explores the mathematical framework of the model, including default processes and the use of reduced-form models.
- The "Empirical Evidences" chapter provides empirical findings regarding the impact of collateralization on swap rates, counterparty credit risk, and market risk. It examines the influence of credit risk and collateralization on swap premium spreads, the relationship between collateralization and credit value adjustment (CVA), and the interaction between collateralization, credit risk, and value at risk (VaR).
Schlüsselwörter (Keywords)
The key words and focus topics of this paper include collateralization, asset pricing, financial system plumbing, swap premium spread, credit value adjustment (CVA), value at risk (VaR), interaction between market and credit risk, and the Credit Support Annex (CSA). This research explores the theoretical and empirical implications of collateralization in the context of OTC derivatives pricing.
Frequently Asked Questions
How does collateralization affect the pricing of OTC derivatives?
Collateralization reduces counterparty risk, which in turn affects the market price of the derivative. Failing to account for it can lead to significant mispricing.
What is the Credit Support Annex (CSA)?
The CSA is a legal document that regulates collateral arrangements between parties in OTC derivative transactions, defining how and when collateral is posted.
Is credit risk the only factor in determining credit-related spreads?
No, empirical evidence suggests that credit risk alone is not enough. Both collateral arrangements and credit risk must be considered to explain unsecured credit costs.
What are the different types of collateralization?
The paper discusses partial, full, and over-collateralization, each having different implications for the risk profile of the contract.
How do market risk and credit risk interact in this model?
The findings indicate important interactions where changes in market prices (market risk) can trigger collateral calls that change the exposure to counterparty default (credit risk).
