Risky Bonds Aren’t So Risky in the Long Run

The world is a risky place, and high-yield debt spreads to safe US Treasury securities are close to historic levels of stinginess, signaling complacency in markets — at least on the surface. But legendary investor Howard Marks says that’s the wrong way to look at it and long-term investors should consider allocations to credit.

I am quite sympathetic to the handwringing about the policy environment. Investors are trying to absorb a bizarre — some might say stagflationary — mix of economic ideas from President Donald Trump, including 19th-century style tariffs and Silicon Valley “move fast and break things”-style government downsizing and layoffs. The former could provide a supply-side shock to prices at the same time that real economic growth may be wobbling. Consumers, businesses and investors don’t know what to think, and that uncertainty is serving as a drag on the economy.

Meanwhile, even after widening about 53 basis points in the past month, the Bloomberg US Corporate High Yield Bond Index still yielded just about 314 basis points, or 3.14 percentage points, above government securities at the time of writing, a spread that’s in the most miserly 15th percentile. Outside of recent experience, the index has only seen spreads this narrow on rare occasions — on and off in the periods of 1994-1998, 2004-2007, 2018 and 2021-2022.

Spreads

Here’s the thing though: To long-term investors, spreads don’t matter as much as all-in yields. You don’t need to be a rocket scientist to understand that prospective long-term returns are largely correlated with prevailing yields at the time of investment. And at 7.5%, those are still toward the middle of their historical distribution (around the 40th percentile). As the graphic below shows, history would suggest that today’s yields should produce decent 10-year returns. While some part of the return depends on default and recovery rates, the yields have a contractual element. You literally get what you pay for.

And the alternatives aren’t much better. Consider that long-run annualized returns for US equities — which have considerably more short-run variability — are only about 10%. Late last year, the clairvoyants at Goldman Sachs Group Inc. looked deep into their crystal balls and divined that S&P 500 Index valuations and concentration could lead to annualized returns closer to 3% in the next decade. If you shun both equities and risky credit, then you’ll have to camp out in Treasuries or high-grade corporates while you wait on a better entrance point, and it might not come as soon as you think.
