"[W]hat we see unfolding is the latest chapter in the tug of war between inflationary and deflationary forces. During the “goldilocks” economy of the last decade, investors levered themselves up. Homeowners treated their homes as if they were ATMs; banks set up off-balance sheet Special Investment Vehicles (SIVs); governments engaging in arrangements to get cheap loans that may cost future generations dearly. Cumulatively, it was an amazing money generation process; yet, central banks remained on the sidelines, as inflation – according to the metrics focused on - appeared contained. Indeed, we have argued in the past that central banks lost control of the money creation process, as they could not keep up with the plethora of “financial innovation” that justified greater leverage. It was only a matter of time before the world no longer appeared quite so risk-free. Rational investors thus reduced their exposure: de-levered. When de-leveraging spreads, however, massive deflationary forces may be put in motion. The financial system itself was at risk, as institutions did not hold sufficiently liquid assets to de-lever in an orderly way. Without intervention, deflationary forces might have thrown the global economy into a depression.
"The trouble occurs when the money creation process takes on a life of its own, because the money destruction process is rather difficult to stop. However, it hasn’t stopped policy makers from trying: in an effort to fight what may have been a disorderly collapse of the financial system, unprecedented monetary and fiscal initiatives were undertaken to stem against market forces. Trillion dollar deficits, trillions in securities purchased by the Fed with money created out of thin air (when the Fed buys securities, it merely credits the account of the bank with an accounting entry – while no physical dollar bills are printed, many – including us – refer to this process as the printing of money)."
