I credit derivatives nell’economia dei sistemi finanziari tra innovazione e criticità
2011
Il lavoro è volto a comprendere il ruolo degli strumenti credit derivatives nell’economia dei sistemi finanziari. I credit derivatives rappresentano una significativa forma di innovazione finanziaria che incide direttamente sull’attività degli intermediari finanziari e, in particolare, bancari. Il ricorso al mercato dei credit derivatives rende possibile il trasferimento integrale o parziale dei rischi di credito senza il contestuale trasferimento delle singole esposizioni creditizie. Ciò dischiude una varietà di scelte aziendali di de-integrazione della catena del valore dell’intermediazione creditizia e di diversificazione del portafoglio crediti che, tuttavia, non sempre conducono ad una…
Robust Recovery Risk Hedging: Only the First Moment Matters
2009
Credit derivatives are subject to at least two sources of risk: the default time and the recovery payment. This paper examines the impact of modeling the recovery payment on hedging strategies in a reduced-form model as well as a structural model. We show that all hedging approaches based on a quadratic criterion do only depend on the expected recovery payment at default and not the whole shape of the recovery payment distribution if the underlying hedging instrument (say, a defaultable zero coupon bond) jumps to or reaches a pre-specified value when the credit event occurs. This justifies assuming a \emph{certain} recovery rate conditional on default time and interest rate level. Hence, th…
Portfolio diversification in the sovereign credit swap markets
2018
We develop models for portfolio diversification in the sovereign credit default swaps (CDS) markets and show that, despite literature findings that sovereign CDS spreads are affected by global factors, there is sufficient idiosyncratic risk to be diversified. However, we identify regime switching in the times series of CDS spreads and spread returns, and the optimal diversified strategies can be regime dependent. The developed models trade off the CVaR risk measure against expected return, consistently with the statistical properties of spreads. We consider three investment strategies suited for different CDS market participants: for investors with long positions, speculators that hold unco…
Credit derivatives disclosure in banks’ risk reporting: Empirical evidence from four large European banks
2019
This paper aims to analyze the derivatives disclosure in banks’ annual risk reports. In this paper, the author uses content analysis to examine the qualitative and quantitative profiles of the derivatives disclosure at a cross-country level, with particular reference to credit derivatives. The empirical research is conducted on a sample of large European banks. The paper also shows that there is room to improve various aspects of derivatives disclosure, and provides some useful insights for further research. The derivatives disclosure in banks’ annual risk reports has deep managerial, financial, regulatory and accounting implications at a firm and industry levels, and the comprehension of t…
Is There a Credit Risk Anomaly in FX Markets?
2015
This paper explores whether a link between sovereign credit ratings and currency returns exists. Perhaps contrary to expectations, it finds that currencies of countries with higher credit risk tend to generate lower returns than those with a lower credit risk. The credit risk spread cannot be explained by standard risk factors.
Credit derivatives e catena del valore del rischio di credito: le determinanti delle scelte di de-integrazione.
2013
This paper analyses the drivers of the credit risk transfer market in the credit risk value chain. The central line of my research is to explain why the credit derivatives market is a case of credit risk value chain disintegration. I examine the determinants that explain the use of credit derivatives by banks in the lending business. Transaction cost economics represents the starting point of my research. Competitive advantages of banking firms, standardization of information and financial instruments, financial regulation and shareholder value view help us understand the creation of credit risk transfer markets.
Multi-Agent Financial Network (MAFN) Model of US Collateralized Debt Obligations (CDO)
2014
A database driven multi-agent model has been developed with automated access to US bank level FDIC Call Reports that yield data on balance sheet and off balance sheet activity, respectively, in Residential Mortgage Backed Securities (RMBS) and Credit Default Swaps (CDS). The simultaneous accumulation of RMBS assets on US banks’ balance sheets and also large counterparty exposures from CDS positions characterized the $2 trillion Collateralized Debt Obligation (CDO) market. The latter imploded at the end of 2007 with large scale systemic risk consequences. Based on US FDIC bank data, that could have been available to the regulator at the time, the authors investigate how a CDS negative carry …
