On the credit risk of OTC derivative users
Journal Article
What explains the growth in commodity derivatives?
This article documents the massive increase in trading in commodity derivatives over the past decade?growth which far outstrips the growth in commodity production and the need for derivatives to hedge risk by commercial producers and users of commodities. During the past decade, many institutional portfolio managers added commodity derivatives as an asset class to their portfolios. This addition was part of a larger shift in portfolio strategy away from traditional equity investment and toward derivatives based on assets such as real estate and commodities. Institutional investors? use of ...

The emergence and future of central counterparties
The authors explain why central counterparties (CCPs) emerged historically. With standardized contracts, it is optimal to insure counterparty risk by clearing those contracts through a CCP that uses novation and mutualization. As netting is not essential for these services, it does not explain why CCPs exist. In over-the-counter markets, as contracts are customized and not fungible, a CCP cannot fully guarantee contract performance. Still, a CCP can help: As bargaining leads to an inefficient allocation of default risk relative to the gains from customization, a transfer scheme is needed. A ...

Frictional Intermediation in Over-the-Counter Markets
We extend Duffie, G?arleanu, and Pedersen?s (2005) search theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers? valuations or inventory costs. We develop a solution technique that makes the model fully tractable and allows us to derive, in closed form, theoretical formulas for key statistics analyzed in empirical studies of the intermediation process in OTC markets. A calibration to the market for municipal securities reveals that the model can generate trading patterns and prices that are ...

Measuring counterparty credit exposure to a margined counterparty
Firms active in OTC derivative markets increasingly use margin agreements to reduce counterparty credit risk. Making several simplifying assumptions, I use both a quasi- analytic approach and a simulation approach to quantify how margining reduces counterparty credit exposure. Margining reduces counterparty credit exposure by over 80 percent, using baseline parameter assumptions. I show how expected positive exposure (EPE) depends on key terms of the margin agreement and the current mark-to-market value of the portfolio of contracts with the counterparty. I also discuss a possible shortcut ...
