3 Colliding Macro Trends Set to Put U.S. Economy to the Test

It’s ironic that I had planned this column a couple of days ago and started writing it yesterday because the very concerns I talk about below are behind the overnight news that Fitch is lowering its long-term debt rating for US government bonds one notch to AA+. That matches S&P’s rating (Moody’s is still at Aaa).

Let me say at the outset that I am not at all concerned that the US will renege on its bonds in the classic sense of refusing to pay. Classically, a government that can print the money in which its bonds are denominated can never be forced to default. It can always print interest and principal.

Yes, this would cause massive inflation, and so would be a default on the value of the currency. Again classically, this is no decision at all. However, it bears noting that there may be some cases in which the debt is so large that printing a solution is so bad that a country may prefer default so that bondholders, and not the general population, take the direct pain. I don’t think this is today’s story or probably this decade’s story. Probably.

But let’s get back to what I intended to talk about.

Here are three big-picture trends that are tying together in my mind in a way that bothers me:

  1. Large and increasing (again) federal deficits
  2. An accelerating trend toward onshoring production to the US
  3. The Federal Reserve continuing to reduce its balance sheet

You would think that two of the three of those are unalloyed positives. The Fed removing its foot from the throat of debt markets is a positive, and re-onshoring production to the US reduces economic disruption risks in the case of geopolitical conflicts and provides high-value-added employment for US workers. And, of course, all of that is true. But there’s a way these interact that makes me nervous about something else.

This goes back to the question of where the money comes from to fund the Federal deficit. I’ve talked about this before. In a nutshell, when the government spends more than it takes in, the balance must come from either domestic savers or foreign savers. Because “foreign savers” get their stock of US dollars from our trade deficit (we buy more from Them than They buy from us, so we send them dollars on net which they have to invest somehow), looking at the flow of the trade deficit is a decent way to evaluate that side of the equation. On the domestic side, savings come mainly from individuals and, over the last 15 years or so, from the Federal Reserve. This is why these two lines move together somewhat well.
