摘要: | 本文以2001至2011年间,获得中华信评公司及惠誉信评台湾分公司给予本国商业银行的长期信用评等及信用评等的调整作为风险的衡量指标,探讨金控组织对银行风险的影响。实证结果发现,第一、当银行所属的金控是以保险与证券为主体时,银行加入金控可以获得中华信评给予较佳的评等等级。显示加入非银行之金融控股公司被信评机构视为可以达到分散风险的效果,因而给予较佳的评等等级。但当银行加入以银行为主体之金控,则未获得中华信评给予较佳的评等。当银行所属金控是以证券或以银行为主体时,并未使银行获得台湾惠誉给予较佳的评等等级。其次、中华信评与台湾惠誉调整银行的评等等级并未受到该银行是否隶属于金控子公司的影响,本国银行评等等级调整主要受到银行资产品质的影响。第三、在控制其他财务、股权及公司治理变数之后,金控公司评等的调整对银行的评等调整有显着的影响,此结果在中华信评与台湾惠誉均成立。 Using commercial banks assigned credit ratings by Taiwan's rating Corp. (TRC) or Fitch's Taiwan Branch from 2001 to 2011 as samples, we investigate the effects of financial holding organization on bank rating and rating changes. The results show, first, banks are assigned a favorable rating when it is affiliated with Insurance FHCs or Security FHCs but cannot obtain a favorable rating when it is affiliated with Bank FHCs when considering TRC's ratings. Second, FHC organization does not affect credit rating agencies' rating adjustment and the main factor affecting bank ratings is asset quality. Third, bank rating changes are affected by FHCs rating changes after controlling other financial information, ownership structure and corporate governance variable and the results hold for TRC and Fitch's Taiwan Branch. |
