Managing Counterparty Risk in OTC Derivatives

by Amol Dhargalkar, Director of Corporate Advisory Services, Chatham Financial

Prior to early 2008, managing counterparty risk across derivatives was low on the list of factors that most firms considered in the hedging and risk management process. While always a discussion point, the fall of Bear Stearns, Lehman Brothers, AIG and subsequent bail-outs of a large swathe of the financial industry across the world has brought managing counterparty risk to the forefront of many hedging discussions. There are several ways to mitigate the risk of a single counterparty default, but the most appropriate strategy is largely dependent upon the individual firm’s policies and objectives. This article will discuss three common strategies used to manage counterparty risk, and provide a case study example of how one firm manages this risk.

There are several ways to mitigate the risk of a single counterparty default, but most appropriate strategy is largely dependant upon the individual firm's policies and objectives.

One way to mitigate single counterparty risk is to enter into collateral posting agreements with your counterparty. When your portfolio of transactions is an asset to you, your counterparty must post you cash (or cash equivalents) based upon a negotiated Credit Support Annex. While this is an extremely effective method, a number of complications arise in the collateral posting scenario. First, it is highly unlikely that any firm can command one-way posting; apart from some structured vehicle transactions, collateral posting is, at best, almost always a two-way proposition that also forces you to post collateral if your hedging positions become liabilities. Second, it is extremely rare that your counterparty will agree to post dollar-for-dollar cash collateral; typically, your counterparty will only post collateral once the value of the transactions has exceeded a certain level (Threshold), which may be so high as to render the collateral posting arrangement worthless.
