Measuring Counterparty Credit Exposure to a Margined Counterparty

Abstract: Firms active in OTC derivative markets increasingly use margin agreements to reduce counterparty credit risk. Making several simplifying assumptions, I use both a quasianalytic 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 p… Show more

“…The effect of threshold and margin period has been examined by Gibson [12] in a simplified setup, and by Ballotta et al [3] in a more general structural model with jumps. The main insight is that collateralization is not able to fully eliminate counterparty risk, especially in presence of market shocks.…”

“…A challenge for building an advanced approach is the incorporation of collateral [14], which is straightforward in the SA-CCR. For each calculation of exposure max(PV(t) − C(t); 0) per market data scenario and time step, the expected value of the collateral C(t) has to be estimated.…”
