I honestly have no idea how that could happen. Every time people fight me on the crash that never happened after 2007, I always point to the fact that most in the industry probably didn't realize how far the government would go to print so much money, and how low the interest rates would go and how long they would be there for. In the entire history of economics, I don't think these two factors were ever in play.
So it is my belief that the catastrophe was averted because these two mechanisms were enacted and were somehow wildly successful. Going forward, what other tools do the officials have to keep the party going? The problems now are much worse, such as an over-inflated RE market along with equity markets. Could the balance sheet grow another 10 trillion? Sure, but its kind of like pushing on a string at this point. Any extra money the government prints is just going to inflation, so the citizens are screwed. And most of what will be necessary going forward, like energy and food, cannot be printed, so the printing press will be of limited benefit. Clearly interest rates are just coming off their lows, but still historically pretty much at the bottom, unless you want to talk negative rates. So this tool is no longer available as well.
So the point is that back in 2007 the officials were able to pull a rabbit out of a hat via the two extraordinary tools, and now I don't think they have anything left. I almost believe that at this point, the officials want to kill the economy, take a much bigger role in running things, get everyone dependent on the government, and rule through authority. If they don't seize more power now, then when society breaks down even further, it will be all out anarchy. How does the equity market keep rising in this environment, unless of course its simply a crack-up boom in response to a monetary collapse of the USD?
