With the economy tracking 5% growth and junk bond spreads near 266 basis points, the week's inflation and jobs reports will decide whether the bond selloff is about strength or stress.
Markets head into the final days of September with an unusual combination: the highest long-term Treasury yields in 19 years, an economy that appears to be growing at a rapid clip, and a corporate credit market showing almost no sign of worry.
The Atlanta Fed's GDPNow model tracks third-quarter growth at 5.0%, unchanged in its latest update on Sept. 25. High-yield bond spreads, the extra yield investors demand to hold junk debt over Treasuries, stood near 266 basis points as of Sept. 21, a historically tight level. And the government funding cliff that often unsettles markets in late September has been removed: Congress passed a continuing resolution this month, clearing the Senate 90-6, that keeps the government open through Dec. 11.
The all-in cost of risk
Tight spreads can be misleading when base rates are high. Adding a 266 basis point spread to a 10-year Treasury yield near 5.23% puts the rough all-in borrowing cost for a speculative-grade company close to 7.9%. That is expensive money, even if the premium for default risk looks modest. Spreads measure how worried lenders are about defaults relative to Treasuries. They do not capture whether the underlying cost of capital has become a burden.
For now, lenders are betting that strong growth will carry weaker borrowers through. That bet is reasonable while output is expanding at a 5% pace. It leaves little cushion if the week's data signal that inflation is forcing the Federal Reserve to keep raising rates into a slowing economy.
The calendar
Wednesday, Sept. 30, brings the August personal consumption expenditures price index, the Fed's preferred inflation measure, along with a fresh GDPNow reading. Friday, Oct. 2, brings the September employment report at 8:30 a.m. Eastern. The Federal Open Market Committee meets Oct. 27 and 28.
What would move the story
A soft PCE reading paired with a solid jobs number would support the benign case: growth-driven yields, contained inflation and a credit market that is right to be calm. A hot PCE print would sharpen the hawkish repricing already visible in rising yields and a falling gold price. The first place to look for strain would be high-yield spreads. A move meaningfully above 300 basis points would signal that credit investors have started to question whether growth can outrun the rising cost of money.
