I have also said that the enormity of the asset price gains over the last 10 years had increased the danger because reflating the bloated stock, real estate, and public and private debt markets would bring on doses of stimulus that could prove lethal for the economy. But even though I expected that the next financial crisis would be catastrophic, I thought that it would come into the world in the usual way, as a credit crisis triggered by over-leverage. But the Coronavirus ripped up those stage notes, and instead ushered in a threat that is faster and deeper than I imagined, and I imagined a lot. It's a perfect storm, a black swan with teeth.

Even in my most pessimistic assessments, I did not expect that so many seemingly distant sectors of the economy would simultaneously evaporate, almost overnight, or that government deficits would expand to nearly $4 trillion in the first wave of the crisis, or that the Federal Reserve would so suddenly launch its largest-ever experiment in quantitative easing, (with almost none of the forward guidance they have used to telegraph lesser moves), which would expand its balance sheet by more than $3 trillion in a matter of just a few months.
