The interbank network as a multiple network. A schematic representation of the balance sheets of three banks akin to that of Fig. 12.2 is reported. The first layer (light blue color, on the left) represents the exposures banks have to common assets. Shocks on this part of the nexus will impair the asset side of the banks forcing for a balance sheet reduction. The layer in the center (light orange) represents the “traditional” interbank lending. The last layer on the right (light red) represents the CDS network, where pairs of banks are connected if they engage in one of these contracts (links in red). Interestingly, other banks can be the reference entity for a contract (links in purple).

Individual vulnerability vs individual impact (2008 and 2013) Circle size reflects asset size, colors reflect the magnitude of the interbank leverage. The four quadrants divide the banks into four categories.

Example of contract network among three banks. Each bank balance sheet consists of assets and liabilities. The assets of one bank are liabilities of another bank. (Top) Credit contracts are represented as arrows (pale red) from the lender to the borrower. Pale blue arrows represent investment in assets issued by entities external to the banking system. (Bottom) Derivative contracts are represented as orange arrows from the seller to the buyer, while the reference entity is indicated by the violet dashed arrow.
