The document discusses the LIBOR scandal where it was discovered that several major banks had manipulated the London Interbank Offered Rate (LIBOR) for financial gain between 2005-2009. LIBOR is a benchmark interest rate used globally in contracts worth trillions of dollars. The scandal arose when it was found that banks had falsely inflated or deflated their LIBOR submissions to profit off trades or give the impression they were more creditworthy. This manipulation impacted homeowners, municipalities, and other entities. Several banks including Barclays were fined billions and lawsuits were filed against many of the banks involved totaling over $40 billion. The scandal led to calls for reforming how LIBOR is set and regulated.
