Hedging the Counterparty Credit Risk of an Oil Company with Oil Futures Using Dynamic GARCH – A Derivative's Approach to Right-Way Risk

If the creditworthiness of a counterparty is a derivative of a commodity price, there is the potential to have right- or wrong-way exposures in respective commodity transaction. Identifying them is important, because otherwise credit costs might be inadequately calculated and wrong incentives might be set. This is especially important if one wants to do more business in credit risky areas of the world.As concerns publicly listed counterparties I develop a simple approach for identification of "Right Way Risk" (RWR). This approach only works if the stock and commodity price are co-integrated. To set the stage I subsume various models for optimal hedging under one general co-integrated model. In a worked example three models (Bivariate & Univariate Error Correction Model, Conventional Regression Model) are applied to the Chinese oil company Petrochina and RWR is shown for fixed price purchase contracts. The proposed approach might be useful in getting a more accurate picture of credit risk and to structure commodity transactions more rewardingly
