This book offers a comprehensive analysis of the shareholder wealth effects of the financial sector consolidation in the Asia-Pacific region and its impact on the acquirer's cost of debt. By not only examining the capital market reactions to the institutions directly involved in M&A transactions, but also their closest rivals, it is possible to draw clearer conclusions in regard to the overall success of the financial sector consolidation in this region. In addition, by investigating the acquiring institution's CDS market reaction to merger announcements, valuable insights are offered in regard to the difference between equity and debt market perceptions of bank M&As. The analyses suggest that equity and debt markets consider different factors when evaluating the success of mergers.
