Il Credito Cooperativo giunge alla sfida di Basilea 3 dopo un decennio di profonde trasformazioni, che hanno influito sulle politiche creditizie e sulle modalità di gestione dei rischi; i fattori congiunturali continuano a esercitare pressione sul modello di business tradizionale. La prossima...

Many studies have questioned the reliability of banks' calculations of risk-weighted assets (RWA) for prudential purposes. The significant divergences found at international level are taken as indicating excessive subjectivity in the current rules governing banks' risk measurement and capital...

In December 2010 the Basel Committee on Banking Supervision published a set of new regulations for banks in response to the financial crisis. This paper aims at evaluating the possible effects of the new framework on banks' available regulatory capital and risk-weighted assets and assessing...

Stress tests have become a key tool for banks, supervisors and macro prudential authorities. An aspect of these exercises is the need for statistical models to obtain risk measurements under an adverse scenario and a fundamental question is who should develop such models. If models are developed...

In many standard derivation and presentations of risk measures like the Value-at-Risk or the Expected Shortfall, it is assumed that all the model's parameters are known. In practice, however, the parameters must be estimated and this introduces an additional source of uncertainty that is usually...

The level of capital requirement generated by the IRB approach depends crucially on the asset correlation, a parameter that enters the regulatory risk weight formula and is determined by the Regulators. Several studies have estimated the asset correlations and found that the empirical values are...
