It's Never Painless When (Market) Bubbles Pop

Investors are obsessed with predicting the timing of the Fed’s first interest rate hike. Will it raise the Fed Funds rate in September, or wait until next year? But it is far more important to get a grasp on the pace of rate hikes. Will it be a 'one-and-done' move, or does this mark the beginning of an incremental tightening cycle? Those of us who are not in the inner circle are forced to only speculate.

But one thing is certain: If history is any guide, whatever they do, the Fed will get it wrong. Most market commentators place unfounded belief in the Fed’s acumen. But the truth is: I wouldn't trust the Fed to tell me what the weather is going to do in the next 30 seconds--even if they were looking out the window.

Once you understand the nature of bubbles—how they are created and how they burst—you can be assured this latest manifestation will also end in disaster.If the Fed raises rates in the manner in which the dot plots currently suggest, it will quickly burst the bubbles already created in the real estate, stock and bond markets. On the other hand, if the Fed opts to only make a small token move higher in the cost of money it will allow asset bubbles to spin out of control until inflation destroys the vestiges of economic growth.

Our Central Bank has been deluding itself into believing it can easily escape from its nearly $4 trillion expansion of the monetary base and 7 years of virtually free money.But that is a spurious belief. Bubbles never die slowly and always bring aboutdire consequences. The bigger the bubbles the worse the backlash--and never before in the history of economics have central banks distorted market prices to this extent.

All bubbles share the conditions of the asset being overpriced, over-supplied and over-owned when compared to historical norms. And all bubbles are built on a massive increase in debt. For example: the Tech Bubble was fueled by a rapid increase of margin interest, and the housing bubble was fueled by the ownership of properties with little to no equity. Bubbles always sit atop a humongous pile of borrowed money. Today we have a tremendous amount of margin and leverage in both equities and fixed income assets.

For example, we see in this chart from the NYX data website that the percentage growth rate of margin debt vastly outstripped S&P 500 returns in real terms just prior to the collapses of 2000 and 2008.
