Optimal Bidder Selection in Clearing House Default Auctions
Central counterparties' ability to hold successful default auctions is critically important to financial stability. However, due to the unique features of these auctions, standard auction theory results do not apply. We present a model of CCP default auctions that incorporates both the vital, but non-standard, objective of minimizing the likelihood it suffers reputationally damaging losses and the potential for information leakage to affect CCP members' private portfolio valuations. This gives insight into the key question of how CCPs should select auction participants. In particular, we ...

Dealers' Insurance, Market Structure, And Liquidity
We develop a parsimonious model to study the equilibrium structure of financial markets and its efficiency properties. We find that regulations aimed at improving market outcomes can cause inefficiencies. The welfare benefit of such regulation stems from endogenously improving market access for some participants, thus boosting competition and lowering prices to the ultimate consumers. Higher competition, however, erodes profits from market activities. This has two effects: it disproportionately hurts more efficient market participants, who earn larger profits, and it reduces the incentives of ...

Optimal Bidder Selection in Clearing House Default Auctions
Default auctions at central counterparties (or 'CCPs') are critically important to financial stability. However, due to their unique features and challenges, standard auction theory results do not immediately apply. This paper presents a model for CCP default auctions that incorporates the CCP's non-standard objective of maximizing success above a threshold rather than revenue, the key question of who participates in the auction and the potential for information leakage affecting private portfolio valuations. We show that an entry fee, by appropriately inducingmembers to participate or not, ...

Transparency and Collateral : Central versus Bilateral Clearing
Bilateral financial contracts typically require an assessment of counterparty risk. Central clearing of these financial contracts allows market participants to mutualize their counterparty risk, but this insurance may weaken incentives to acquire and to reveal information about such risk. When considering this trade-off, participants would choose central clearing if information acquisition is incentive compatible. If it is not, they may prefer bilateral clearing, when this choice prevents strategic default while economizing on costly collateral. In either case, participants independently ...

Can Broader Access to Direct CCP Clearing Reduce the Concentration of Cleared Derivatives?
In November 2008, at the height of the global financial crisis, leaders from the Group of Twenty (G20) nations, representing the world’s largest economies, convened in Washington, DC, to develop a new regulatory framework to help foster financial stability. They came out of that Washington summit with several noteworthy ideas.1 One was to strengthen over-the-counter (OTC) derivatives markets, where defaults had been serious problems during the financial crisis. In particular, G20 leaders agreed to move more of this business onto regulated exchanges and central counterparties (CCPs) as a way ...

The Role of Primary Dealers in Mitigating Liquidity Risk at U.S. Central Counterparties
In this article, we examine the role of primary dealers as clearing members at U.S. central counterparties (CCPs) and their importance in liquidity risk management at those CCPs. We find that primary dealers are key contributors to concentration in central clearing—they make up a significant portion of clearing members and an even larger portion of activity cleared by U.S. CCPs. Second, we find that primary dealers are a major source of interconnectedness across U.S. CCPs. Further, we estimate that the bulk of clearing activity in the U.S. is conducted by the primary dealers that are also ...

A “Principled” Approach to International Guidance for Central Counterparties
Following the 2007?08 financial crisis, the G20 agreed to implement a clearing mandate, requiring all standardized over-the-counter derivatives to be cleared through a central counterparty (CCP). The central role of CCPs in post-crisis financial markets has increased the interest of both national authorities and international standard setters in CCP regulation.

Central Clearing and Systemic Liquidity Risk
By stepping between bilateral counterparties, a central counterparty (CCP) transforms credit exposure. CCPs generally improve financial stability. Nevertheless, large CCPs are by nature concentrated and interconnected with major global banks. Moreover, although they mitigate credit risk, CCPs create liquidity risks, because they rely on participants to provide cash. Such requirements increase with both market volatility and default; consequently, CCP liquidity needs are inherently procyclical. This procyclicality makes it more challenging to assess CCP resilience in the rare event that one or ...

Collateralized Debt Networks with Lender Default
The Lehman Brothers' 2008 bankruptcy spread losses to its counterparties even when Lehman was a lender of cash, because collateral for that lending was tied up in the bankruptcy process. I study the implications of such lender default using a general equilibrium network model featuring endogenous leverage, endogenous asset prices, and endogenous network formation. The multiplex graph model has two channels of contagion: a counterparty channel of contagion and a price channel of contagion through endogenous collateral price. Borrowers diversify their lenders because of the counterparty risk, ...
