There are, nevertheless, times when there is legitimate cause to restrict price discovery. I’m certainly overjoyed about one form of the Libor price fixing. Libor is a measure of what banks will lend to each other at. Back in the dark days of 2008 banks would not lend to each other. Libor was thus rather high, if it existed at all, but the banks continued to report numbers which were little out of line with the mundane and ordinary. A bit naughty perhaps, but surely preferable to the world’s reference interest rate being quoted as infinite.
