"Modeling wealth dynamics under central clearing"
Time: 11:45 AM
Location: Hill 705
Abstract: We provide a flexible, scalable, and analytically tractable model for participants of a centrally cleared market. By exploiting real-world features of clearing practices, we providing a unifying framework that models, jointly and explicitly, financial institutions' business operations, trading activities, allocation of capital, and the resulting wealth dynamics. We find that (i) trading is more capital intensive for large clearing members, (ii) incomplete information can significantly distort measured concentration, (iii) market collateral demand is positively correlated with wealth concentration, (iv) wealth concentration has the inherent tendency to build up, (v) there is a potential tradeoff between wealth and business diversity, and (vi) a concentration charge on collateralizing margins can be used to steer concentration.
