The rotten heart of finance

From The Economist's print edition

The most memorable incidents in earth-changing events are sometimes the most banal. In the rapidly spreading scandal of LIBOR (the London inter-bank offered rate) it is the very everydayness with which bank traders set about manipulating the most important figure in finance. They joked, or offered small favours. “Coffees will be coming your way,” promised one trader in exchange for a fiddled number. “Dude. I owe you big time!… I’m opening a bottle of Bollinger,” wrote another. One trader posted diary notes to himself so that he wouldn’t forget to fiddle the numbers the next week. “Ask for High 6M Fix,” he entered in his calendar, as he might have put “Buy milk”.

What may still seem to many to be a parochial affair involving Barclays, a 300-year-old British bank, rigging an obscure number, is beginning to assume global significance. The number that the traders were toying with determines the prices that people and corporations around the world pay for loans or receive for their savings. It is used as a benchmark to set payments on about $800 trillion-worth of financial instruments, ranging from complex interest-rate derivatives to simple mortgages. The number determines the global flow of billions of dollars each year. Yet it turns out to have been flawed.

During the early weeks of July 2012, damning evidence has emerged, in documents detailing a settlement between Barclays and regulators in America and Britain, that employees at the bank and at several other unnamed banks tried to rig the number time and again over a period of at least five years. And worse is likely to emerge. Investigations by regulators in several countries, including Canada, America, Japan, the EU, Switzerland and Britain, are looking into allegations that LIBOR and similar rates were rigged by large numbers of banks.

Corporations and lawyers, too, are examining whether they can sue Barclays or other banks for harm they have suffered. That could cost the banking industry tens of billions of dollars. “This is the banking industry’s tobacco moment,” says the chief executive of a multinational bank, referring to the lawsuits and settlements that cost America’s tobacco industry more than $200 billion in 1998. “It’s that big,” he says.
