I think, the crises will be more offen. The reason is simple, the magnitude of the private financial wealth (Bain report) is USD 600 trillion, while world GDP is only around USD 70 trillion. The amount of global currency exchanges is more than USD 1000 trillion (equivalent), while world trade is only USD 18 trillion per year. This is a kind of short-termism, lead to instability. Inter-government finacial flow is supervised by the IMF, but the private global financial flow is without supervision. In reality, the private global financial flow is much bigger the sovereign financial flow.
Yes your article is hitting at the heart of the problem in the short term, and also in the long term.
