(Elsevier, 2015) Alemany, Aida; Ballester Miquel, Laura; González Urteaga, Ana; Gestión de Empresas; Enpresen Kudeaketa
From the 2007 subprime crisis to the recent Eurozone debt crisis,the banking industry has experienced terrible financial instabilitywith increasing volatility levels of bank default probability. UsingEuropean CDS spreads data from January 2006 to March 2013, thispaper sheds light on the impact of three recent significant events ofcredit risk volatility transmission between, firstly, Eurozone andnon-Eurozone banks, and then between distressed peripheral andcore countries inside the Eurozone. We employ an asymmetricmultivariate BEKK model to measure cross-market volatility spil-lovers. We find that both recent crises are distinct episodes. Theglobal financial crisis that originated outside Europe is character-ized by unidirectional volatility spillovers in credit risk from insideto outside the Eurozone. By contrast, the Eurozone debt crisis isrevealed to be local in nature with the euro as the key element,suggesting a financial market fragmentation within the Eurozonebetween distressed peripheral and non-distressed core Eurozonecountries, whereas retaining the local currency has acted as afirewall.
