Bloomberg reported that Barclays’ admission that it rigged the London interbank offered rate (LIBOR) shows regulators, central bankers and politicians weren’t paying attention when everyone from Citigroup to the Bank for International Settlements (BIS) indicated that the measure was being manipulated.
