You may have heard of the Libor scandal, in which at least three and perhaps as many as 16 of the name-brand too-big-to-fail banks have been manipulating global interest rates, in the process messing around with the prices of upward of $500 trillion (that's trillion, with a "t") worth of financial instruments. When that sprawling con burst into public view last year, it was easily the biggest financial scandal in history MIT professor Andrew Lo even said it "dwarfs by orders of magnitude any financial scam in the history of markets."
That was bad enough, but now Libor may have a twin brother. Word has leaked out that the London-based firm ICAP, the world's largest broker of interest-rate swaps, is being investigated by American authorities for behavior that sounds eerily reminiscent of the Libor mess. Regulators are looking into whether or not a small group of brokers at ICAP may have worked with up to 15 of the world's largest banks to manipulate ISDAfix, a benchmark number used around the world to calculate the prices of interest-rate swaps.
Interest-rate swaps are a tool used by big cities, major corporations and sovereign governments to manage their debt, and the scale of their use is almost unimaginably massive. It's about a $379 trillion market, meaning that any manipulation would affect a pile of assets about 100 times the size of the United States federal budget.
