This paradigm has recently been challenged for short time scales,\nwhere interbank markets seem better characterised by a bipartite structure with\nmore core-periphery connections than inside the core. Using a novel\ncore-periphery detection method on the eMID interbank market, we enrich this\npicture by showing that the network is actually characterised by multiple\ncore-periphery pairs. Moreover, a transition from core-periphery to bipartite\nstructures occurs by shortening the temporal scale of data aggregation. We\nfurther show how the global financial crisis transformed the market, in terms\nof composition, multiplicity and internal organisation of core-periphery pairs.\nBy unveiling such a fine-grained organisation and transformation of the\ninterbank market, our method can find important applications in the\nunderstanding of how distress can propagate over financial networks.","url_abs":"http://arxiv.org/abs/1802.05139v1","url_pdf":"http://arxiv.org/pdf/1802.05139v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"structural-changes-in-the-interbank-market","repo_url":"https://github.com/skojaku/core-periphery-detection","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
