Gaming the LIBOR
From Stephen Gandel at Fortune:
Banks took a rate that they artificially set themselves, and then went out and convinced municipalities and pension funds and others to bet against them on the rate. LIBOR rates were supposed to be set by bank treasurers reflecting what it cost them to borrow from other banks. But reportedly a number of bank treasurers consulted traders when deciding what rate to report to the organization in London that collected and posted the rates. (LIBOR stands for the London InterBank Offered Rate) What’s more, traders at a number of banks were given access to the systems that bank officials used to enter the rate so they could overwrite the rates with ones that would better suit them. When the rate went the way Wall Street traders programed it to do, the banks cashed in millions.
