European corporate bonds have become more expensive for companies to refinance, with investment-grade yields rising to 4.4% and high-yield borrowing costs reaching 7%, Goldman Sachs analysts said. The increases come as government bond yields have also risen, although the moves alone do not establish what caused the corporate repricing.

Key Takeaways

  • European investment-grade yields rose about 30 basis points from the start of September, while high-yield costs climbed around 90 basis points.
  • Goldman said companies with near-term refinancing needs or substantial floating-rate debt are particularly exposed.
  • The bank does not expect a systemic credit event, but sees debt costs constraining some companies.

European corporate bonds and sovereign yields

In an October 23, 2026 note, Goldman said European investment-grade spreads over the sovereign risk-free rate had widened by about 24 basis points to 117 basis points since the start of September. High-yield spreads widened by 94 basis points to 354 basis points.

French 10-year government bond yields moved above 5% on October 21 for the first time since 2002. Their spread over German 10-year Bunds peaked above 177 basis points the following day. Both government and corporate borrowing costs have risen, but that does not by itself prove a direct cause-and-effect relationship.

Which companies face the most pressure?

Goldman identified weak cash generation, limited pricing power, near-term refinancing needs and substantial floating-rate debt as potential vulnerabilities. Companies refinancing maturing debt may have to replace it at higher rates, while floating-rate interest costs can reset as rates change.

The analysts said Stoxx 600 companies’ interest expense had risen from 1.25% to 1.85% of sales since 2022, reducing earnings by more than 5% over the period. They estimated that a quarter of the index’s debt must be refinanced within two years and a further quarter is floating-rate debt.

Management teams could respond by focusing on reducing leverage, potentially leaving less capital for investment or shareholder returns, the analysts said.

The wider financing picture

Earlier European Central Bank research on sovereign-to-corporate credit risk describes how sovereign stress can affect companies through fiscal measures and less favorable bank lending conditions. The research examines an earlier period and does not establish the cause of the 2026 market moves.

Goldman also expects bond issuance by US hyperscalers to increase from $250 billion in 2026 to $420 billion in 2027 as large technology companies seek funding. The bank sees rising debt costs as a growing constraint for some companies, but said it does not expect a systemic credit event.
