Abstract:

The credit risk concentration was responsible for great losses in the recent financial crises, notably the 2008 one. With the increasing use of mobile banking and the advance of digital banking services, the way banks measure and recognize concentration risk has changed significantly. In this systematic review, we show that terms like connectedness and interdependency are becoming more common to represent the possibility of a counterpart to increase the risk of an institution. In this context of complexity, Network Theory has emerged as an important tool to solve many of the problems that traditional techniques are unable to deal with.
