Network analysis of cross-correlations on forex market during crises. Globalisation on forex market

Abstract

Within the paper, the problem of globalisation during financial crises is analysed. The research is based on the Forex exchange rates. In the analysis, the power law classification scheme (PLCS) is used. The study shows that during crises cross-correlations increase resulting in significant growth of cliques, and also the ranks of nodes on the converging time series network are grow-ing. This suggests that the crises expose the globalisation processes, which can be verified by the proposed analysis.
