本文以台資銀行美國分行參與美國聯貸市場之實務為研究核心，並以槓桿授信監理要求作為主要觀察切面，探討美國監理機關如何將相關要求落實於金融檢查，以及台資銀行美國分行如何透過授信流程、總分行治理及三道防線架構加以回應。透過整理聯貸市場運作流程、美國槓桿授信相關監理規範及我國銀行業內部控制制度與三道模型架構，再輔以半結構式訪談資料，分析台資銀行美國分行於授信作業、金檢應對及風險管理上的真實境況。研究發現，第一，美國金融監理機構對於槓桿授信監理，重視整體作業流程，涵蓋案件辨識、授信審查、貸後管理等整體作業內容。第二，美國監理機關重視金融機構是否具備獨立風險管理能力，以及是否建立足以支撐風險辨識、資料留存、持續監控及缺失改善之內部控制機制。第三，台資銀行美國分行於應對美方監理要求時，雖多已具備一定程度之授信審查、法令遵循、風險管理及稽核監督架構，惟實務上仍面臨三項主要挑戰：其一，聯貸次級市場案件於正式成為貸款人前，資訊取得與資料完整性有限，增加案件初期之資訊不對稱及參貸風險；其二，台
美兩地於市場慣例、文件取得及聯貸籌組時效上存在差異，使總行與分行間於授信條件及風險判斷上可能產生落差；其三，分行之金檢應對與監理溝通能力，亦直接影響缺失認定及後續監理壓力。
本文認為，台資銀行美國分行能否有效承接美國槓桿授信監理要求，關鍵在於能否反映海外市場特性，並透過總分行間有效之資訊回報、權責分工與治理協作，轉化為可持續運作之管理與控制機制。基於研究結果，本文建議台資銀行於參與美國授信案件時，宜建立更具彈性之差異化跨境授信審查機制，總行強化分行協作與前兩道防線之授權，並建立外部專業顧問之常態性對接機制，以提升海外分行面對當地監理要求之應對能力。

This study examines how U.S. regulators implement leveraged lending requirements through financial examinations and how Taiwanese bank branches in the United States respond through credit processes, head office–branch governance, and the three lines model.
Based on syndicated loan practices, U.S. leveraged lending regulations, Taiwan’s banking internal control framework, and semi-structured interviews, this study analyzes practical issues in credit operations, examination responses, and risk management.
The findings show that U.S. leveraged lending supervision focuses on the overall credit process, including transaction identification, credit review, post-lending management, and governance arrangements. U.S. regulators also emphasize independent risk management and internal control mechanisms that support risk identification, document retention, ongoing monitoring, and remediation. Although Taiwanese bank branches generally have credit
review, compliance, risk management, and audit oversight mechanisms in place, they still face challenges such as limited information access in secondary-market syndicated loans, differences in market practices and syndication timing, and supervisory pressure arising from examination response quality.
Accordingly, this study suggests that Taiwanese banks establish more flexible crossborder credit review mechanisms, strengthen head office–branch coordination and the empowerment of the first and second lines of defense, and maintain regular engagement with external professional advisors to enhance overseas branches’ ability to respond to local regulatory requirements.
