在當前競爭態勢下，台灣金融市場的發展，勢必朝向跨業經營的方向前進。我國亦於民國九十年六月二十七日通過金融控股公司法，賦予台灣金融業跨業經營的法源，為國內金融業創造成為金融集團的契機，以達成金融跨業經營現代化、國際化的目標。雖然金融機構業務營運多樣化，但金融機構承擔風險亦隨之增加，金融監理機制在面臨這樣的挑戰下勢必得做一番調整，才能持續扮演健全及穩定國內金融體系的重要角色。 我國主管機關對於金融控股公司要求以合併基礎計算資本適足比率，並訂定了「金融控股公司合併資本適足性管理辦法」，以期能發揮適度的監理功能。然該辦法中僅以簡單的加減乘除運算求得之資本適足率，是否為反映集團資本需求的良好指標實不無疑問。因此，本文除了研究國際監理官組織所發布的相關報告外，並藉由介紹和討論歐盟指令對金融集團的補充監理原則和措施，如：資本適足性、集團內部交易、風險集中等問題，以及美國對於金融控股公司之相關監理規範，加以比較研究後，來探討我國現行規範是否妥當，並提出相關監理制度改善之建議，以期能作為我國建構健全金融市場之參考。 / Under current competitive circumstances, the development of Taiwan’s financial market will be bound to move forward in the direction of cross-sector business. In Taiwan, Legislative Yuan also has passed the “Financial Holding Company Act” in June 2001. With the passage of the act, it not only gives Taiwan’s financial institutions authority to operate cross-sector activities, but also creates a trigger for financial institutions to become financial conglomerates in order to meet the objectives of financial modernization and globalization. Although financial institutions may diversify their business, additional risks may arise. Financial regulatory mechanisms have to adjust their function to ensure the safety and soundness of financial system. Our competent authorities demand financial holding companies calculating their capital adequacy ratio on a consolidated basis, and enact “Regulations Governing the Consolidated Capital Adequacy of A Financial Holding Company.” However, in this regulation, the ratio was calculated in simple aggregated method, and it is doubtful that such ratio is a good index to reflect consolidated capital requirement. Therefore, this thesis not only studies on related publications issued by international supervision organizations, but also introduces EU Financial Conglomerate Directive with regard to some supervisory issues (e.g. capital adequacy, intra-group transactions and risk concentrations etc.) and U.S. framework for financial holding company supervision. After investigating and comparing different models, this study tries to find whether current regulation is appropriate or not, and make some suggestions concerning the supervisory system in order to construct a sound financial market as a reference in our country.
