An anonymous insider from one of Britain's biggest lenders ... explains how he and his colleagues helped manipulate the UK's bank borrowing rate. Neither the insider nor the bank can be identified for legal reasons. It was during a weekly economic briefing at the bank in early 2008 that I first heard the phrase. A sterling swaps trader told the assembled economists and managers that Libor was dislocated with itself". What the trader told us was that the bank could not be seen to be borrowing at high rates, so we were putting in low Libor submissions, the same as everyone. How could we do that? Easy. The British Bankers' Association, which compiled Libor, asked for a rate submission but there were no checks. The trader said there was a general acceptance that you lowered the price a few basis points each day. According to the trader, "everyone knew" and "everyone was doing it". There was no implication of illegality. After all, there were 20 to 30 people in the room - from management to economists, structuring teams to salespeople - and more on the teleconference dial-in from across the country. The discussion was so open the behaviour seemed above board. In no sense was this a clandestine gathering. Libor had dislocated with itself for a very good reason - to hide the true issues within the bank.
