Sometimes it seems the financial markets inhabit a parallel universe to ordinary folk. UBS shares ended Wednesday down just 0.3%, apparently unfazed by a $1.5bn fine from US, UK and Swiss regulators for no less than 2,000 attempts to rig the London interbank offered rate.

The bank admitted criminal conduct by its Japanese subsidiary and individual employees face criminal charges. Similarly, Barclays shares actually rose when it became the first bank to be fined for its role in rigging Libor.
