The standard measures of distress risk ignore the fact that firm defaults are correlated and that some defaults are more likely to occur in bad times. We use risk premium computed from corporate credit spreads to measure a firm’s exposure to systematic variation in default risk. Unlike...

Asymptotic Single Risk Factor (ASRF) model is used to derive the regulatory capital formula of Internal Ratings-Based approach in the new Basel accord (Basel II). One of the important assumptions in ASRF model for credit risk is that the given portfolio is well diversified so that one can easily...

This paper analyzes the measurement of credit risk capital requirements under the new Basel Accord (Basel II): the Internal Rating Based approach (IRB). It focuses in the analytical formula for its calculation, since its derivation to the main assumptions behind it. We also estimate the credit...

This report presents an application of a macro stress testing procedure on credit risk in the Romanian banking system. Macro stress testing, i.e. assessing the vulnerability of financial systems to exceptional but plausible macroeconomic scenarios, maintains a central role in macro-prudential...

In the present document it is exposed in an abstract way the models of credit portfolioes CreditMetricsTM, KMV, CreditRisk+, Credit Portfolio View in such a way that they could be calibrated and implemented in financial institutions where the quality and quantity of credit information is scanty,...

This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk...

In this work, we solve a risk measurement problem, which involves both credit and market risk. Specifically, We deal with the problem of pricing a synthetic CDO tranche and with the assessment of the evolution behavior of value of the net income resulting from the exposure to a single credit...

This document presents several Credit Risk tools which have been developed for the Credit Derivatives Risk Management. The models used in this context are suitable for the pricing, sensitivity/scenario analysis and the derivation of risk measures for plain vanilla credit default swaps (CDS),...

This paper explores the difficulties involved in quantitative measurement of operational risk and proposes simulation methods as a practical solution to obtain the distribution of total losses. It also introduces an example of the estimation of expected and unexpected losses, as well as...
