Static Models of Central Counterparty Risk

                                          Samim Ghamami

The 2009 G20 clearing mandate has increased the importance of central counterparty
(CCP) risk management substantially. International standard setting bodies (SSBs) have outlined
a set of principles for CCP risk management; they have also devised CCP risk capital
requirements on clearing members for their central counterparty exposures. There is still no
consensus among CCP regulators, bank regulators, and CCPs on how central counterparty risk should
be measured coherently in practice. A conceptually sound definition of the CCP risk capital in the
absence of a unifying CCP risk measurement framework is challenging. Incoherent CCP risk capital
requirements may create an obscure environment that disincentivizes the central clearing of over
the counter (OTC) derivatives contracts. more...


Restoring Value to Minimum Variance

 Forthcoming in Journal of Investment Management

                                         Lisa Goldberg
                                         Ran Leshem
                                         Patrick Geddes

A long-only investable minimum variance strategy outperformed the S&P 500 over the four decades from January 1973 to December 2012. Through the lens of
a factor model, we show this outperformance can be largely attributed to implicit style bets. Specifically, minimum variance has thrived by tilting away from size and volatility and toward value. As funds have poured into minimum variance in the wake of the financial crisis, and plausibly as a consequence of this trend, the value tilt has disappeared and a momentum tilt has emerged. more...

Centralized Clearing for Over-the-Counter Derivatives

                                         Gordon Rausser
                                         William Balson
                                         Reid Stevens

Systemic risk propagated through over-the-counter (OTC) derivatives can best be managed by a public-private central counterparty clearing house (CCP). Though private CCPs provide an adequate amount of clearing’s private good, they do not provide the socially optimal level of the public good or impure goods. By undersupplying both public and impure goods, private CCPs may exacerbate the conditions under which financial crises develop and propagate. A public-private partnership could align incentives so that the CCP produces the socially optimal level of the private, public, and impure goods. We propose using an RFQ platform with an active transaction permissioning system that uses position risk based on Monte Carlo simulation to estimate default risk and a two-part pricing scheme to efficiently price the risk retained by the clearing function. more...

Pretrade and Risk-based Clearing: A Case Study of American International Group’s Super Senior CDS Portfolio 2005-2008

                                         William Balson
                                         Gordon Rausser

Risk-based clearing has been proposed by Rausser, Balson, and Stevens [2010] for over-the-counter (OTC) derivatives. The Board of Governors of the Federal Reserve Board in FRB [2011] recognize that clearing requires collateral or margin to be posted in order to assure a high likelihood of protection for the clearinghouse from default of its covered contracts. Readily implemented and well understood methodologies are available for setting margin levels at both the contract and portfolio level. more...


The Decision to Lever

                                         Robert M. Anderson
                                         Stephen W. Bianchi
                                         Lisa R. Goldberg

Even among the most conservative and highly regulated investors such as US public pension funds, the use of levered investment strategies is widespread and growing. In the period since the financial crisis, strategies such as risk parity that explicitly lever holdings of publicly traded securities have emerged as candidates for these investment portfolios. more...
