"I think CDS desensitise lenders/arrangers to credit risk. It's like having a quickie divorce available after a drunken wedding in Las Vegas. Debt should be like a marriage with each party knowing it is to a large extent binding. Without the quickie "out" that CDS offer, credit risk would have been respected more and less credit would have been extended."
