But Greenspan does share the blame
Alan Greenspan in “A response to my critics”, FT’s economist forum, April 6, says that “The core of the subprime problem lies with the misjudgements of the investment community”; and the core of that misjudgement lies of course with the credit rating agencies; as most of the other financial agents were just doing their normal business which is selling something risky valued at somewhat less risky terms.
In this case what Wolf fails to recognize, sufficiently at least, is that the immediate detonator of the current crisis was not a housing bubble but a bubble in financial securities, such as those collateralized by lousily awarded mortgages to the subprime sector.
The credit rating agencies did not do the job they were supposed to do, to err is human; but the responsible for empowering the credit rating agencies to do the risk measurement for the markets and ignoring the “to err is human” part of it all, were the bank regulators, like Greenspan. And for this Greenspan should at least stand up and take his share of the blame.
