Spread on CCC-Rated U.S. Corporate Bonds Jumps to 985 Basis Points
Key Facts
The spread on CCC-rated U.S. corporate bonds rose 17 basis points to 985 basis points on Monday, September 28, according to Bloomberg index data cited by Bloomberg Law. The spread has risen by more than 100 basis points since the start of the month, signaling a higher premium investors demand to hold lower-rated debt. The move comes amid concerns about companies shifting assets beyond creditors’ reach, tactics the story’s summary said had added fuel to the sell-off. The available information does not establish that these practices alone explain the spread widening or quantify investor losses. Nor does it provide details on the assets moved or the entities to which they were transferred.
Market watchers see spreads continuing to widen if the Federal Reserve delivers additional rate increases, according to Bloomberg Law. Those increases could eventually pressure corporate earnings, in their view, and make it harder to refinance maturing debt. They could also raise borrowing costs for companies that need to extend maturities. That prospect puts weaker-credit companies’ financing under a dual test: servicing existing debt and securing alternative funding. Market watchers said spreads “could continue to widen” as rates weigh on earnings and refinancing.
Pressure spread to global credit markets in October, with the yield spread on global corporate bonds reaching 129 basis points on Thursday, October 22, its widest level since May 2025, according to Bloomberg. Coverage linked the widening to growing investor concern about technology companies borrowing to fund artificial intelligence and rising oil prices. The measure indicates the yield premium investors demand on corporate bonds relative to benchmark bonds, while the 129-basis-point level marks a widening not seen since the date cited. In the week of October 17, the yield on lower-rated CoreWeave bonds jumped to 15%. A Bloomberg report described that as a level “usually indicative of financial distress” and raised concerns that buyers of high-risk bonds were becoming less willing to finance tech startups.
The moves reverse a stronger period for lower-rated bonds earlier in the year. In May, high-yield debt credit spreads were near their lowest levels in two decades, according to Bloomberg. Lower-rated bonds also continued to outperform investment-grade bonds, with a 1.6-percentage-point performance gap through May 21, the largest to that point in 2026. But the lowest-rated U.S. CCC bonds did not fully participate in that performance in April: they had gained 1.38% year to date through April 21, slightly lagging B- and BB-rated bonds. Bloomberg reported that investors were then concerned about artificial intelligence’s impact on software companies.
In September, SoftBank raised the equivalent of $11.1 billion through dollar- and euro-denominated bonds to fund its artificial intelligence ambitions, according to Bloomberg. The report said the company’s borrowing costs remained substantially higher than what it had paid previously, as concerns about financing the expansion of artificial intelligence reverberated through credit markets. On October 30, U.S. Treasury yields fell as technology stocks declined. The 10-year Treasury yield dropped by as much as 5 basis points to 4.89% during Asian trading, its lowest level since September 10, according to Bloomberg. The Treasury move came amid a decline in technology stocks, while credit spreads and financing trends for lower-rated companies remained a focus of investor concern.
