What was Barclays guilty of? It was caught rigging the Libor (London Interbank Offered Rate). The Libor is the interest rate which banks charge to borrow from each other. It affects the cost of financial contracts from mortgages to loans. WHO was involved? Between ten and 20 rogue dealers, according to the Financial Services Authority, in a four-year period up to 2009. None of them has been named. WHY did they do it? The bankers raised and lowered the Libor rate to suit their needs. At times they plotted to keep the Libor rate low to make their bank look good. A high rate suggests a bank is weaker than its rivals. At other times the bankers raised the Libor to boost their profits — and their own individual bonuses.
