Research in banking less focuses on bank obedience. The issue of bank obedience describe the roles of central bank in maintain the banks health through rules and regulation such as Basel II, and CAMEL. This research investigates the obedience of bank on CAMEL and the effect of their obedience on...

The Basel Accord assumes an inverse relationship between the probability of default and the asset correlation parameter, with the latter being responsible for modeling the degree of cyclicality of default rates. Previous empirical studies that embedded the formula of the Basel Accord into a...

In credit portfolio modeling the asset correlation parameter is used to describe the degree of default rates fluctuations. In this article we estimate the asset correlation parameter for banks and other industry sectors from default data. We find that estimates of the asset correlation vary...

The 2008-2009 financial crises revealed that the Basel Accord of 2004 was inadequate to ensure a stable financial sector. In this paper we analyze whether the Basel Accord's assumption of a single risk factor contributed to the instability. The asset correlation parameter describes the degree of...

This paper presents a credit gap for Malta derived from a semi-structural multivariate filter. This modelling approach has several advantages over univariate approaches typically used, for example to construct the Basel gap. The multivariate filtering of observed data into trends and cycles is...

The goal of the Basle II regulatory formula is to model the unexpected loss on a loan portfolio. The regulatory formula is based on an asymptotic portfolio unexpected default rate estimation that is multiplied by an estimate of the loss given default parameter. This simplification leads to a...

The paper proposes an application of the survival time analysis methodology to estimations of the Loss Given Default (LGD) parameter. The main advantage of the survival analysis approach compared to classical regression methods is that it allows exploiting partial recovery data. The model is...

The paper proposes a new method to estimate correlation of account level Basle II Loss Given Default (LGD). The correlation determines the probability distribution of portfolio level LGD in the context of a copula model which is used to stress the LGD parameter as well as to estimate the LGD...

We analyze the cyclicality of risk weights of banks in the Czech Republic from 2008 to 2016. We differentiate between risk weights under the internal ratings-based and those under the standardized approach, consider the financial cycle, and employ wavelet coherence as a means of dynamic...
