Our back of the envelope calculation is that first-order effects in the US will be 10% of GDP, with further ripple effects from there. Our assumptions are fairly simple. Net additions to household debt ranged between $800 billion to $1.2 trillion from 2002 to 2007. That number fell to $77 billion in Q2 and negative $117 billion in Q3. All data come from the Fed Z.1 Flow of Funds release. We merely assume that net consumer credit will go to zero, whereas it could go severely negative as defaults and debt repayment have already caused outstanding credit to fall. We further assume that household savings will rebound from approximately zero to halfway back to the historic 10% range. The cumulative impact would be to reduce personal consumption by $1.3-1.6 trillion or between 9% and 12% of GDP.
Granted not all of this will hit US production. Much of the damage will occur in the export economies as we stop buying from them. We have repeatedly argued as much. Outsourcing which destroyed jobs in the US and made the target nations prosperous is now going in reverse and this should provide a partial circuit-breaker to the US economy which MAY prevent a consumption-employment-income-consumption death spiral like the 1930s. On the other hand, business spending is also falling and that swing is far more difficult to estimate. For modeling purposes, the hit to US output from lower capital spending should be roughly equal in size to the reduced demand for imports so US GDP probably declines 9-12% - straddling the 10% line of the textbook definition of depression.
Unless people dig themselves even deeper into a debt hole, households will not take on further debt - either out of prudence or inability. It would have been extraordinarily difficult to stop this a year and virtually impossible now. Once the (misplaced) confidence evaporated, the conclusion became inevitable.
I'd like to thank Karl Denninger of Ticker Forum for his inimitable description of the current crisis. The PG version of which runs:
We're screwed, but they're screwed worse.We are indeed seeing just how bad the rest of the world has it right now. The NY Times did an excellent piece over the weekend that described the rapid decline of world trade. Here's the money quote:
Over all, the total reported exports from those 43 countries peaked in July, at $1.03 trillion. By November, the figure was down 26 percent, to $766 billion. Since the figures are seasonally adjusted, the monthly figures should be comparable.This is not just a problem for Asia but a global one. German exports fell 21%. Over a quarter of all world trade went away in only FOUR MONTHS. I think this is a pretty good example of just how much credit distorted the US and world economy. At some point, credit goes from a useful organ to a cancer. We have often spoken of the Universal Debt bubble and the breathtaking size and scope of it. It was "fun" while it lasted but the bill for the UDB is about to come due. The check is on its way to the table and we're going to spend a lot of time arguing over who gets to pay for it. George Washington spoke of government but it applies to credit as well and the distinction between the government and the banks grows ever smaller:
... a troublesome servant and a fearful master. Never for a moment should it be left to irresponsible action.
