Large jumps in the idiosyncratic component of bank CDS spreads significantly reduce the equity value of peers, particularly on the event day. The negative externality does not hinge on the “information connectedness” between the two entities as proxied by characteristics such as common core line of business, common country or region, and inter-country common legal tradition. The negative externality is stronger in turmoil market conditions when risk-aversion levels are higher and/or investors are subject to pessimism. The more fragile the risk profile of the event bank and peer firm prior to the event the stronger the cross-transmission. The findings lend support to the wake-up call paradigm at micro level, and are insightful towards a better assessment of the vulnerability of the financial system.engtechnical reporthttps://www.ucm.es/icaeopen accessC13C58G14G20Credit Risk EventsCredit Default SwapsEquity valueEuropean bankingCross-transmissionWake-up Call.Bancos y cajasEconometría (Economía)Finanzas5302 Econometría
