Early on in the global government finance Bubble, I advanced the concept of the “Moneyness of Risk Assets.” This was an evolution from the mortgage finance Bubble period’s “Moneyness of Credit” market distortion. The aggressive use of rate policy and central bank balance sheets/Credit to promote stock and bond price inflation nurtured the (central bank backstop-induced) perception of risk assets as safe and liquid stores of value (i.e. money-like). Over time, this had momentous effects throughout the markets, certainly including the booming ETF and derivatives complexes.
