Abstract: In credit risk, besides assessing risk of credit applications, it has been very critical to take a proactive decision by foreseeing the risk of non-performing loan (NPL). In Turkey, recent reports demonstrate that among different credit categories such as consumer, corporate, small and medium-sized enterprises (SME) loans, SMEs reflect the highest NPL ratios. This paper focuses on SME credit behavioural scoring to develop an early NPL warning system after the credit is released. Utilizing application scoring features together with behavioural scoring features, an experimental study of classifying SME customers as non-performing or performing is targeted during lifetime of the credit. The proposed system aims to support a warning 6 months ahead to detect NPL state. Random Forest (RF) algorithm is implemented for NPL state classification of active SME credits. Accuracy results of RF algorithm is compared with different machine learning algorithms like Logistic Regression, Suppo rt Vector Machine and Decision Trees. It has been observed that accuracy of RF model is increased when different SME credit product features are added to the model. An accuracy ratio of 82.25% is achieved with RF which over performs all other alternative algorithms. (More)
