本文討論九一一之後反恐戰爭的金融層面。自布列敦森林體制在一九七○年代開始逐漸崩毀，國際金融體系為國際資金流動打開了方便之門。恐怖組織就利用這個國際金融環境將錢移往世界各地，從事恐怖活動。真要漬除恐怖組織的財務力量，各國必須合作。但是因為一些開發中國家的金融體系不透明，開發中國家對國際金融的規範也有不同的看法，反恐戰爭的金融前線、戰線和戰事都將拖得很長。

This paper examines the financial front of the War on Terrorism. It argues that financial globalization in the wake of the decline of the Bretton Woods system provides multiple channels for international financial transactions. Terrorist groups make good use of this new environment to transact money to finance their causes. To weed out terrorist money, the international financial system relies on individual countries to cooperate in implementing regulatory measures, but inter-state cooperation is hampered either by some countries’ opaque financial systems or by national differences in their financial systems. Thus, the financial front of the War on Terrorism is going to be a drawn-out process.
