Why surging yields aren’t spooking corporate borrowers: Marty Fridson
TLT•The 10-year Treasury yield rose from 3.96% in February to 5.31% on October 5, while the US investment-grade corporate bond spread narrowed from 86 to 84 basis points between February and September. Marty Fridson argues that higher yields do not necessarily signal rising corporate default risk.
1. Spreads narrowed as yields rose
The 10-year US Treasury yield climbed from a 2026 low of 3.96% in February to a 24-year high of 5.31% on October 5. Over the same period through September, the spread on ICE Indices’ US investment-grade corporate bond index fell from 86 to 84 basis points.
2. Why the relationship can differ
Fridson says corporate spreads usually narrow as Treasury yields rise, a pattern confirmed by academic studies. High yields can reflect strong demand for capital in a vibrant economy, while spreads can widen during economic weakness or market panic even as policy rates fall. Higher-than-expected inflation can also benefit borrowers by reducing the value of debt repayments.
3. Borrowing costs adjust gradually
Higher rates can raise companies’ borrowing costs and reduce profitability, but the effects may not appear immediately or fully. Companies spread debt maturities over many years, so only a portion of investment-grade debt typically needs to be refinanced in the near term. Fridson says elevated yields on medium- to high-quality bonds do not appear to come with a significant increase in default risk.
