Markets are not the economy, but it's still important to understand and follow economics.

One of the unfortunate "trends" of 2020 was the increase in debt at various levels. Now, debt can be a good thing … it greases the international wheels and can be an important part of long-term financial plans for countries (in the same way you or I might use it.)

But too much of a good thing is a bad thing, and doing that math gets pretty complicated on the national level. 

To help put it in perspective, I want to look at the U.S. debt on different scales. 

First, you can look at this US Debt Clock for a staggering interactive visualization of the inflows and outflows in America. Click the image to watch it update in real-time.  I encourage you to look at some of the components tracked.  It made me think about our future differently.

The U.S. has a GDP of about $22 Trillion and our national debt is currently over $28 Trillion, but our net worth is still approximately $120 trillion. 

For more perspective: 

• The global economy has hugely increased in size in the last 50 years as developing nations prosper. The average global GDP per capita has gone from ~$1000 to over $10,000 in my lifetime.
• The U.S. has the largest percentage of the world's debt, but Japan has the worst debt-to-GDP rate at over 224% (compared to America's approximately 127%)
• During 2020, debt held by the US public increased by $4.2 billion – the largest dollar increase in history. A large part of that increase in debt was due to the federal deficit which was reported at $3.1 billion
• Over 39% of U.S. Federal debt is foreign-owned, though we earn more from our assets abroad than we pay to foreign investors
• The average American has over $90,000 in debt, and approximately 80% of Americans are in debt 

What about on the state level?

As a result of snowballing debt, President Biden's $1.9T economic stimulus package promised $350B in direct aid to states.

To help understand the image, Texas is actually a great case study. Texas's bubble is big because it has one of the highest total debt levels, but is green because its debt ratio is pretty good at 62.5%. 

California has the highest total debt, but is very light pink, stating that its debt ratio isn't bad.  Some states' liabilities outweigh their assets by a factor of 4x or 5x which is scary. 

This is a helpful illustration of the delicate balance of taking on debt. It's okay to take on large amounts of debt if you have a reasonable belief that revenue outstrips interest. To contrast that, some of these states have unsustainable debt levels – and only survive because they're a part of a bigger whole – the U.S. – and have an extra safety net. 

What about Consumer Debt?

Most of America's debt is Federal – but consumer debt accounts for a non-trivial portion as well.  Here's a chart that shows the change in U.S. Household debt since 2003.

Student, Auto, and Home Owner loans have all increased substantially – with the cost of student loans raising over 500%. Almost every category of consumer debt has increased. 

While our country has gotten richer, and the standard of living has increased, we also have more people living in large amounts of debt. 

Things To Consider

These charts are startling. Debt is a powerful tool … but comes with risk as well. The question is, are we as a country and individuals managing the risk appropriately?

It's hard to look at these charts and say that there isn't an issue. The hope is that the government stimulus packages will make a difference – but Band-Aids won't fix the root of the problem and can even lull people into a false sense of security. 

What do you think the solution is?

I spend a lot of time doing research … not the way data scientists do, but I enjoy keeping an eye on the pulse of things. 

Recently, I've noticed increasing talk about bubbles. One of the most obvious potential "bubbles" being the relatively stable bullish performance of the markets, despite the lack of a full economic recovery. 

Interestingly, Ray Dalio's bubble indicator says that stocks aren't at dangerous levels, though it does say the top 5% of the top 1,000 US companies are in an extreme bubble. Many of those companies are emerging technology companies.

So, without making a prediction, caution is probably fair, but recognize that people aren't blaring sirens and running with their arms flailing in the air. 

Instead of focusing as much on today's bubbles, I thought I'd share a great summary on "how to spot a bubble" by Barry Ritholz. 

He suggests 10 elements: 

1. Standard Deviations of Valuation: Look at traditional metrics –  valuations, P/E, price to sales, etc. — to rise two or even three standard deviations away from the historical mean.

2. Significantly elevated returns:  The S&P500 returns in the 1990s were far beyond what one could reasonably expect on a sustainable basis. The years around Greenspan’s “Irrational Exuberance” speech suggest that a bubble was forming:

1995    37.58
1996    22.96
1997    33.36
1998    28.58
1999    21.04

And the Nasdaq numbers were even better.

3. Excess leverage: Every great financial bubble has at its root easy money and rampant speculation. Find the leverage, and speculation won’t be too far behind.

4. New financial products: This is not a sufficient condition for bubble, but it does seems that each major bubble has new products somewhere in the mix. It may be Index funds, derivatives, tulips, 2/28 Arms.

5. Expansion of Credit:  This is beyond mere speculative leverage. With lots of money floating around, we eventually get around to funding the public to help inflate the bubble. From Credit cards to HELOCs, the 20th century was when the public was invited to leverage up.

6. Trading Volumes Spike: We saw it in equities, we saw it in derivatives, and we’ve seen it in houses: The transaction volumes in every major boom and bust, almost by definition, rises dramatically.

7. Perverse Incentives: Where you have unaligned incentives between corporate employees and shareholders, you get perverse results — like 300 mortgage companies blowing themselves up.

8. Tortured rationalizations: Look for absurd explanations for the new paradigm: Price to Clicks ratio, aggregating eyeballs, Dow 36,000.

9. Unintended Consequences: All legislation has unexpected and unwanted side effects. What recent (or not so recent) laws may have created an unexpected and bizarre result?

10. Employment trends:  A big increase in a given field — real estate brokers, day traders, etc. — may be a clue as to a developing bubble.

11. Credit Spreads: Look for a very low spread between legitimately AAA bonds and higher yielding junk can be indicative of fixed income risk appetites running too hot.

12. Credit Standards: Low and falling lending standards are always a forward indicator of credit trouble ahead. This can be part of a bubble psychology.

13. Default Rates: Very low default rates on corporate and high yield bonds can indicates the ease with which even poorly run companies can refinance. This suggests excess liquidity and creates false sense of security.

14. Unusually Low Volatility: Low equity volatility readings over an extended period indicates equity investor complacency.

There are many ways to make money trading … and even more ways to lose money trading.  If it were easy, everyone could do it.  There is a mix of art and science combined with hard-to-quantify factors at play.

But, survivorship bias is big in trading because hindsight is 20/20. It's easy to look at a popped bubble and say "oh, obviously that was a bubble" … but if it was that easy, trading wouldn't be so hard.

Trends continue until they don't … but at some point, they don't, and that's where people get hurt. 

My gut tells me it is time to pay closer attention.

Onwards!
