An extendable, integrated, and dynamic approach to forecasting and stress-testing credit risk

Marcel Muller, Arno Botha, Conrad Beyers

An integrated and extendable approach for stress-testing loan portfolios is presented, which includes both a loan production component and a credit risk component. In this approach…

The loss optimisation of loan recovery decision times using forecast cash flows

Arno Botha, Conrad Beyers, Pieter de Villiers

A theoretical method is empirically illustrated in finding the best time to forsake a loan such that the overall credit loss is minimised. This is predicated by forecasting the fut…

Simulation-based optimisation of the timing of loan recovery across different portfolios

Arno Botha, Conrad Beyers, Pieter de Villiers

A novel procedure is presented for the objective comparison and evaluation of a bank's decision rules in optimising the timing of loan recovery. This procedure is based on finding…

Deep Learning and Statistical Models for Time-Critical Pedestrian Behaviour Prediction

Joel Janek Dabrowski, Johan Pieter de Villiers, Ashfaqur Rahman +1

The time it takes for a classifier to make an accurate prediction can be crucial in many behaviour recognition problems. For example, an autonomous vehicle should detect hazardous…

A procedure for loss-optimising default definitions across simulated credit risk scenarios

Arno Botha, Conrad Beyers, Pieter de Villiers

A new procedure is presented for the objective comparison and evaluation of default definitions. This allows the lender to find a default threshold at which the financial loss of a…

A framework for simulating systemic risk and its application to the South African banking sector

Nadine M Walters, Conrad Beyers, Gusti van Zyl +1

We present a network-based framework for simulating systemic risk that considers shock propagation in banking systems. In particular, the framework allows the modeller to reflect a…
