The banks allowed the situation to develop though, and were far too highly leveraged. They knew the risks that they were taking, where the financial products they had developed were offered to lower-income people with little understanding of the risk.
The banks allowed the situation to develop but there were very few economists who signalled any warnings on the consequences. Those few who did were not 'mainstream', in that they didn't subscribe to the mainstream 'ruling theory' (i.e a theory which is dominant over other theories) of neo classical economics.
In fact, according to Steve Keen, a non mainstream economists, the Dutch economist Dirk Bezemer looked through economic literature to identify people who could legitimately claim to have predicted the GFC . He identified only 12 out of the thousands of economists who were happy with the developing situation. The 12 are listed on Keen's blog if anyone wants to check (you may have to register as a 'free' subscriber before you can read the blog)

A longer extract from a very long blog post about non 'orthodox economists and economic theory.
... "Those of us who have looked to the self-interest of lending institutions to protect shareholders’ equity, myself included, are in a state of shocked disbelief,” testified Federal Reserve Chairman Alan Greenspan before Congress. “The whole intellectual edifice, however, collapsed in the summer of last year". What’s worse, this massive humiliation of the economic orthodoxy was attached at the hip to an equally massive victory for the economic heterodoxy. For it was precisely economists of the dissident schools—employing completely different models from those of the mainstream, rooted in different principles derived from the historic analysis of financial markets—who did successfully predict the crash. And not just in the manner of those dogmatic Marxists who, as the old joke goes, “predict” 12 of the past 2 crises of capitalism. Rather, using tools like stock-flow consistent models and Minskyan crisis theory,33 heterodox economists such as Wynne Godley and Michael Hudson not only proclaimed in print (far in advance) that a financial crisis would happen but also identified its specific origin and causes in the real estate market. Here was as neat a natural experiment as anyone could ask for, and the winner was clear to anybody with eyes to see.

The Greenspan quote is found all over the place in economic literature. He was Chair of the US Federal Reserve. He was in a position to evaluate the actions the financial institutions and to do something about them if he felt that they were threatening the financial stability of those institutions. His belief, as an economist, in the neoclassical economic theories made him confident that the institutions were doing nothing untoward.
TBH, if Greenspan couldn't see it coming and neither could any of the similarly influenced economists depended on by the UK government I don't see how we can blame the non economist PM of the time for going along with them.
To say the 'banks self regulate through boom and bust' is just repeating a neoclassical economic theory which has been proved to be untrue. It's based on a supposition that they are rational actors, and the neoclassical idea that markets shouldn't be interfered with in any way because they are self regulating. Calling for more regulation seems to me to be contradictory if one believes that the neoclassical theory is correct.
