Economic Seismology: Forecasting The Next Economic Collapse

Why America’s Trade Deficit Will be at the Heart of the Next Economic Collapse

Ask ten physicists where an asteroid will be in one year and you’ll get one (right) answer.  Ask ten economists where the economy will be a year from now and you’ll get ten answers—all wrong.

The disheartening truth is that economists are notoriously bad at prediction.  We saw this recently with the 2008 Financial Crisis: very few economists saw it coming, and fewer still knew when it would hit.

There are many reasons for this: the time-horizon is often too long to provide economists with adequate feedback, meaning they cannot learn from their mistakes; there is paradoxically too much and too little data, ensuring that economists either lose the signal in the noise or have nothing to work with; and many economists are paid to profess certain positions.

My point: economic prediction is pointless.

But that doesn’t mean we’re helpless.  Economists may not be able to predict the next crisis but they can make forecasts.  The difference is important.



A physicist can predict, with certainty, where a billiard ball will travel if struck.  Economists traditionally liken themselves to physicists: the economy is a giant pool table governed by laws like supply and demand, and if we have enough information we can predict its behavior.  This is a terrible analogy, and it explains why economists are often wrong.

The economy is more like earth’s atmosphere or the human mind because it is a complex system, governed by second-order causality: its emergent properties tangle cause-and-effect chains to such a degree that prediction is impossible.

At best, economists can identify areas of systemic weakness, places where the economy is most vulnerable to shocks and contagion.  Knowing where trouble is likely to occur is valuable because it gives us time to plan—we cannot stop the next earthquake, but we can figure out where the fault lines are and plan accordingly.

Fault Lines: the US Trade Deficit

Contrary to what liberals at the Washington Post claim, the trade deficit poses huge risks to America’s economy.  It is the smouldering fault line.  Why?

It exacerbates the problem of debt-fragility, and it is the ideal conduit for (otherwise isolated) economic contagion to infect America.

But first, what is the trade deficit?   Simply put: America runs a trade deficit when it buys more stuff from foreign countries than it sells.  It is when our imports are greater than our exports.  Right now America is running a massive trade deficit, and has done so every year since 1973.  In 2016 America’s goods trade deficit was $750 billion, and we also ran a services surplus of $250 billion.  Therefore, America’s overall balance of trade was negative $500 billion in 2016.  The deficit is large, and has been growing for decades.

How do we pay for the deficit?  After all, there is no such thing as a free lunch.  There are four, and only four, ways for America to acquire foreign goods:

1. We could get them for free via theft or gifts.  Unless we’re prepared to become Viking raiders, or default on all of our foreign debts, this probably isn’t a viable option.

2. We could trade our own goods for them: this would result in a neutral balance of trade.  We’re doing this, obviously, but we’re not selling enough to balance the books.

3. We could trade for them using stuff we made in the past—ie. selling off assets like stocks and land.  This results in a trade deficit.

4. Or we could buy foreign goods using stuff we promise to make in the future, that is debt like US Treasury Bills or corporate bonds.   This also results in a trade deficit.

America runs a trade deficit, which necessarily means we are paying for it using options three and four, that is by selling assets and debt.  The data bears this out.

Foreigner investors—flush with cash from their trade surplus with America—now own 20 percent of all US equities.  This is up from just 12 percent in 2007.  Likewise, foreigners have bought up billions-worth of physical property in America—everything from penthouse suites in New York to ranches in Oklahoma.

In 2015 alone, foreigners purchased over $100 billion of American real estate.  This is partly why houses are 73% more expensive (in real terms) today than they were in the 1970s—we traded “cheap goods” for expensive housing.

Foreign entities (governments and private investors) also bought US debt with their trade surpluses, which is part of the reason government spending is so out-of-control—the trade deficit ensures foreigners are a replenishing source of capital.

Currently foreign investors (governments and individuals) own some 44 percent of America’s national public debt, valued at over $6.3 trillion.  Not only must this principle sum eventually be repaid, but we also owe interest on it which will cost taxpayers hundreds of billions over the coming decades.

America’s national debt has been increasing dramatically in recent years. In part, this growth’s been fueled by our trade deficit—we buy foreign goods in exchange for debt.

Furthermore, foreigners also bought-up much of America’s private market, and now own 29 percent of all US corporate bonds.

The same is true of US household debt: although the 2008 Recession cooled down this metric (slightly), we’re gearing up for more borrowing.  We didn’t learn our lesson.

Now for the golden question: why does any of this matter?

Crystal Goblets & Hydra

Although there are many economic and political reasons for reducing the trade deficit, I would like to focus on a reason that receives very little attention: fragility.

Something is fragile if it is harmed more than it is helped by volatility.  The classic example is a crystal goblet: change can only hurt it.

Contrast this with the mythological beast hydra, which grows two heads for everyone one it loses.  Crystal goblets hate volatility, Hydra loves it.

Back to economics.  The trade deficit creates fragility in a number of ways.  To begin with, foreign trade necessarily increases national fragility by increasing economic interdependence: the more America depends upon foreign products, the more we can be harmed by logistical or price disruptions (volatility).  Likewise, large trade deficits mean we depend more on our trading partners than they depend upon us: this strips us of leverage should things go south.  Trade is important, but it’s possible to have too much of a good thing.

The trade deficit also makes America fragile by feeding our debt addiction.  My favorite stock-trader-turned-philosopher Nassim Taleb notes that high debt loads create fragility by limiting optionality—high debt limits our room to maneuver in times of financial crises.

Furthermore, there is a psychological component at play in that people are far more likely to panic when they are highly indebted.  Panic is what causes everything from bank-runs to stock market crashes.  It’s why little hiccups tend to snowball.

Most importantly, trade deficits simply aren’t sustainable.  As has been noted, we pay for the trade deficit by selling off assets and debt.  Eventually we will run out of property to sell and our debt will be too expensive to service.  What then?  At that point we’ll either need to reduce our consumption by buying fewer imports, or increase our output to trade for foreign goods.  Right now we’re living in a consumption bubble, and to pay for it we’re selling our inheritance and mortgaging our future.

Eventually, the bubble will burst, and when it does we will be worse off than if we had never ran the deficit in the first place.  This is attested to both historically and theoretically.  For example, Great Britain ran a large and persistent trade deficit at the end of the Victorian Era which contributed to the country’s economic decline.

Likewise, the economist Joseph Stiglitz has shown that chronic trade deficits inevitably lead to consumption declines when the bubble bursts.  In fact, his models suggest that it’s a “mathematical certainty.”  The piper always gets paid.

How to Survive the Next Economic Collapse

It’s impossible to predict exactly when and where the next big earthquake will hit—but we do know where the fault lines are, and we can build our buildings more robustly.

The same is true when it comes to economics.  We don’t know what will cause the next economic crisis, but we do know that big trade deficits and high debt loads will inevitably make it worse.

We need to make America’s economy robust again before the big one hits
