The Spider Network: The Wild Story of a Math Genius, a Gang of Backstabbing Bankers, and One of the Greatest Scams in Financial History

The Spider Network tracks the manipulation of LIBOR, the foundational interest rate used to price trillions of dollars in global contracts. David Enrich centers the narrative on Tom Hayes, a socially awkward math prodigy at operations like UBS and Citigroup who exploited his talent for arbitrage to move the daily rate. Through a network of brokers and traders across rival firms, Hayes organized a systematic process of submitting false data to profit on massive derivative trades. The book details how this technical loophole flourished due to a lack of institutional oversight and a banking culture that rewarded aggressive, unethical profit-seeking.

Financial professionals and true-crime readers choose this book to understand the mechanisms of large-scale white-collar fraud. It clarifies how a single benchmark index impacts mortgage rates and student loans, showing the direct link between high-level trading floors and the broader economy. Readers walk away with a specific technical understanding of how LIBOR functioned, the legal fallout of the subsequent scandals, and the reality of how individual traders became scapegoats for systemic failures within major global banking institutions.
