“…The classification of SIBs and shocks coming from SIBs have been at the helm in designing and implementing macroprudential policies (such as the systemic risk buffer) since the Global Financial Crisis (GFC) of 2007-2008. Since the financial meltdown of the GFC (Silva et al, 2017), financial institutions' insolvencies, and lowering the availability of credit in the global economies, several theoretical studies have found a link between systemically important banks and their contribution to systemic risk (e.g., Zhou, 2009;Caccioli et al, 2012;Elliott et al, 2014). Evidence shows that SIBs, regarded as too big to fail, inflict a negative externality on the system and endanger financial stability (Moch, 2018). In a highly interconnected banking system, the failure of a large bank could lead to systemic failure exposing the dependencies: the proportion of losses in a failed bank's portfolio will be transferred to other banks through the interbank market, the payment system, or through asset prices.…”
