John Lanchester wrote an account of the 2008 global financial meltdown and he tells FiveBooks that nothing has been done since the crisis. If Barclays tomorrow were to announce, ‘Really sorry, we’ve just lost a trillion dollars betting on whether the Chinese renminbi would appreciate, and it hasn’t, and can we have our bailout now?’, the state would have no choice but to say, OK, they’re too big, and too systemically important. The implosion was more than a year and a half ago, and it’s all completely unfixed. It’s as if they’d performed some heroic feat of steering and then immediately fell asleep at the wheel.
