摘要：This study examines the impact of syndicated loans on individual and national diversity of loan portfolios of the six largest Canadian banks, as well as their marginal contribution to Canadian systemic risk. To test the marginal impact of Canadian syndicated loans on risk, we use a simulation of fictitious loan portfolios to create benchmarks based on syndicated loans along with Hirschman-Herfindahl index and Euclidian distance measures. Our results show that syndicated loans have a positive impact on industrial diversity for each bank's loan portfolio. Empirical results also suggest that lenders’ involvement in industries in which they lack expertise tends to develop a more homogeneous and concentrated national loan portfolio. Finally, we conclude that the homogenization of loan portfolios and the concentration of the national loan portfolio have an ambiguous impact on Canadian systemic risk. Specifically, the impact depends on the systemic risk measure and an industry effect is present.
