Any reform should obviously have to start with the most direct causes of the crisis
Fact one: The single most important detonator of the current difficulties in the financial sector was the securities that had been collateralized with truly lousy mortgages awarded to the subprime sector in the US.
Fact two: The single most important factor that allowed truly lousy mortgages to morph into prime paper was the high prime ratings awarded the collateralized securities by the credit rating agencies.
Fact three: If we survive this there is nothing to stop us following again as lemmings the credit rating agencies over an ever worse precipice.
And so if there is a need for a reform that would be taking away the power of the credit rating agencies to impose their will on the markets.
But then of course Plender could be arguing that this would have to be included in a sort of minimum reform, not at all radical; and in that he would have a point.
