The United States is now committed to using two relatively sophisticated approaches to measuring capital adequacy: Basel III and stress tests. This paper shows how stress testing could mitigate weaknesses in the way Basel III measures credit and interest rate risk, the way it measures bank...

We propose a methodology for measuring the market-implied capital of banks by subtracting from the market value of equity (market capitalization) a credit-spread-based correction for the value of shareholders' default option. We show that without such a correction, the estimated impact of a...

We contribute to the empirical literature on the impact of shocks to bank capital in the euro area by estimating a Bayesian VAR model identified with sign restrictions. The variables included in the VAR are those typically used in monetary policy analysis, extended to include aggregate banking...

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...

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...

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...

Historical Simulation (HS) and its variant, the Filtered Historical Simulation (FHS), are the most popular Value-at-Risk forecast methods at commercial banks. These forecast methods are traditionally evaluated by means of the unconditional backtest. This paper formally shows that the...

One of the implications of the creation of Basel Committee on Banking Supervision was the implementation of Value-at-Risk (VaR) as the standard tool for measuring market risk. Since then, the capital requirements of commercial banks with trading activities are based on VaR estimates. Therefore,...

This paper assesses the sensitivity of solvency stress testing results to the choice of credit risk variable and level of data aggregation at which the stress test is conducted. In practice, both choices are often determined by technical considerations, such as data availability. Using data for...

The objective of this research is to develop a structural form probability of default model for small and medium-sized enterprises, dealing with the methodological issues which arise in the modelling of small commercial loan portfolios, and to test the applicability of the model in practice....
