Run for your lives! A baby has peed in the pool!
And so, when compared to other official interest manipulations, like what happens when regulators dole out risk weights based on perceived risks to set the specific capital requirements for banks, The Libor Affair is basically the same as a little baby peeing in a big swimming pool. If chemical elements are used to detect it, and water turns blue, then everyone screams, though in fact no one really needs to care that much about it.
What really should upset us all is The Basel Affair, the greatest and most dangerous interest rate manipulation ever.
