倫敦銀行同業拆放利率(London interbank offered rate；簡稱Libor)目前是國際間最重要且最常被應用的市場利率，也是全球貸款方與債卷發行人普遍參考的利率，銀行藉由借存利率的差別而獲取利潤。2006年，一個由金融從業者、生意人以及股票經紀人所形成的怪異組合，在一個極聰明數學家的主導下，上演一齣讓自己荷包滿滿的詐欺戲碼。
另一個名為”村莊白癡”(village idiot) 股票掮客，利用報銷帳目而大量獲利。
In 2006, an oddball group of bankers, traders and brokers from some of the largest financial institutions made a startling realization: Libor―the London interbank offered rate, which determines the interest rates on trillions in loans worldwide―was set daily by a small group of easily manipulated administrators, and that they could reap huge profits by nudging it fractions of a percent to suit their trading portfolios. Tom Hayes, a brilliant but troubled mathematician, became the lynchpin of a wild alliance that included a prickly French trader nicknamed “Gollum”; the broker “Abbo,” who liked to publicly strip naked when drinking; a nervous Kazakh chicken farmer known as “Derka Derka”; a broker known as “Village” (short for “Village Idiot”) who racked up huge expense account bills; an executive called “Clumpy” because of his patchwork hair loss; and a broker uncreatively nicknamed “Big Nose” who had once been a semi-professional boxer. This group generated incredible riches ―until it all unraveled in spectacularly vicious, backstabbing fashion.
