The 2007-2009 financial crisis was a perfect "black swan" event: unexpected, a rarity, with broad and deep impacts; and, with the benefit of hindsight, it was also retrospectively rationalised by many "experts". We got it all "sensationally" wrong: bankers (like myself), policy-makers, supervisors, auditors, research analysts, economists, civil society itself. And even as the crisis was unfolding, many initially did not consider its seriousness. We saw dangers of shocks, but underestimated the confluence and impact thereof.
