Considerations for the allocation of non-default losses by financial market infrastructures

Staff Analytical Note 2022-16 Daniele Costanzo, Radoslav Raykov
Non-default losses of financial market infrastructures (FMIs) have gained attention due to their potential impacts on FMIs and FMI participants, and the lack of a common approach to address them. A key question is, who should absorb these losses?

Decomposing Large Banks’ Systemic Trading Losses

Staff Working Paper 2024-6 Radoslav Raykov
Do banks realize simultaneous trading losses because they invest in the same assets, or because different assets are subject to the same macro shocks? This paper decomposes the comovements of bank trading losses into two orthogonal channels: portfolio overlap and common shocks.

Asymmetric Systemic Risk

Staff Working Paper 2022-19 Radoslav Raykov, Consuelo Silva-Buston
Bank regulation presumes risks spill over more easily from large banks to the banking system than vice versa. Interestingly, we observe this is not the case. We find that the capacity to transmit risk is larger in the system-to-bank direction, leading to an increased default risk.

Systemic Risk and Portfolio Diversification: Evidence from the Futures Market

Staff Working Paper 2021-50 Radoslav Raykov
This paper explores how the Canadian futures market contributed to banks’ systemic risk during the 2008 financial crisis. It finds that core banks as a whole traded against the periphery, in this way increasing their risk of simultaneous losses.

Systemic Risk and Collateral Adequacy

Staff Working Paper 2019-23 Radoslav Raykov
Many derivatives markets use collateral requirements calculated with industry-standard but dated methods that are not designed with systemic risk in mind. This paper explores whether the conservative nature of conventional collateral requirements outweighs their lack of consideration of systemic risk.

Multibank Holding Companies and Bank Stability

Staff Working Paper 2018-51 Radoslav Raykov, Consuelo Silva-Buston
This paper studies the relationship between bank holding company affiliation and the individual and systemic risk of banks. Using the 2005 hurricane season in the US as an exogenous shock to bank balance sheets, we show that banks that are part of a holding parent company are more resilient than independent banks.

Stability and Efficiency in Decentralized Two‐Sided Markets with Weak Preferences

Staff Working Paper 2017-4 Radoslav Raykov
Many decentralized markets are able to attain a stable outcome despite the absence of a central authority (Roth and Vande Vate, 1990). A stable matching, however, need not be efficient if preferences are weak. This raises the question whether a decentralized market with weak preferences can attain Pareto efficiency in the absence of a central matchmaker.

To Share or Not to Share? Uncovered Losses in a Derivatives Clearinghouse

Staff Working Paper 2016-4 Radoslav Raykov
This paper studies how the allocation of residual losses affects trading and welfare in a central counterparty. I compare loss sharing under two loss-allocation mechanisms – variation margin haircutting and cash calls – and study the privately and socially optimal degree of loss sharing.
