Is the Global Economy Headed for a “Worst Case” Scenario?

For some, the idea of another economic depression on the scale of the 1930s seems impossible. But here’s a shocking statistic—with debt-to-GDP around 300% and an average global interest rate of say 2%, we need 6% nominal GDP growth indefinitely just to break even. I’ve written before about why the next market downturn could be one of the worst in history. Just as pilots spend a lot of time training in a simulator preparing for challenging events, it’s important for investors to mentally rehearse what they will do when the markets end up in a tailspin.

The first step is to acknowledge the risks. Debt creates fragility that leaves us prone to two major risks: inflation and deflation.

The Deflationary Scenario

In a deflationary scenario, the price of goods comes down usually due to overcapacity built during an overly optimistic period (think real estate in the mid-2000s and oil recently.) With too much competition, businesses struggle to maintain pricing power, and as revenues decrease, there is a smaller profit pool from which to pay wages. This creates a downward feedback loop of less spending and less earning, driving prices lower and lower.

In our current environment, there is another factor: debt. There is already too much of it in the world. With deflation, everyone (governments, corporation and individuals) would have less income to pay off their debts, and some percentage of borrowers wouldn’t be able to repay, therefore defaulting. And since one person’s debt is another person’s asset, the lender must write off the loan and take a hit on their balance sheet, further depressing their income. Theoretically, this downward spiral could go on until the economy fell apart, and in the Great Depression, prices fell about 25% before they started stabilizing.

From an investment standpoint, anything fixed that actually gets paid back does well during a deflationary period. For example, if you hold cash or a high-quality bond, as the price of goods drops, those assets become more valuable in real terms. As a general rule, when facing deflation, good investments are cash and bonds, and poor investments are stocks and commodities.

The Inflationary Scenario

Inflation is usually caused by governments printing too much money and/or when some resource (i.e., labor or capital) becomes scarce relative to current economic growth. With more money chasing a limited amount of goods, prices go up. Once this trend starts, fear of ever-increasing prices can accelerate the process.

Inflation can act like a debt jubilee, as the real value of debt falls dramatically. It creates winners and losers indiscriminately. Think of it this way: if someone owes you $1,000 in 10 years, but we have 20% inflation per year, that $1,000 you’re due is only worth about $161 when it’s paid back. The people who were prudent savers get punished (because their savings are worth less), and the people who were spendthrifts (like many governments around the world) get the reward of unshouldering their debt burden at a fraction of the cost.
