The mother of all systemic risks

Sir, when Richard Beales reports (April 2) that “Uproar forces Moody’s into U-turn over bank ratings” he gives compelling evidence to what some of us have been voicing for almost a decade now, namely that to give some few credit rating agencies so much decision power about how the world’s financial flows should be allocated will, sooner or later, implode or explode into a crisis, as that carries within itself the genetically coding for the mother of all the systemic risks. By reading their “theological discussion” of “how to factor into ratings the possibility that some banks were unlikely ever to be allowed to fail even if they appeared financially weak” you surely must conclude that we might have all been placed on a vicious circle that could perhaps only end with the demise of the by then the world’s only remaining bank. On a side issue, can you sue your credit rating agency for the losses caused by the additional market volatility that his change of heart creates?
