The Era of Cheap Corporate Debt Is Over. Which Businesses Are Most Exposed?
U.S. Treasury yields have climbed sharply, raising the benchmark cost of borrowing for companies that need fresh financing. The 10-year Treasury yield recently reached about 4.82%, its highest level since 2023. The effect is especially important for weaker businesses because their borrowing rates are normally priced at a premium over government debt.
Corporate America is hardly facing one uniform debt problem. Large, highly rated businesses can often issue bonds even when interest rates rise. Companies with weaker credit ratings, heavy leverage or large refinancing needs face a much harder calculation. Debt that seemed affordable when rates were unusually low can become expensive when it reaches maturity and must be replaced.
Why Refinancing Matters More Than Yesterday’s Interest Rate
A company does not immediately pay today’s market rate on every bond it has issued. Existing fixed-rate debt continues carrying its original coupon until maturity. The pressure arrives when that debt must be refinanced.
Imagine a business that issued long-term bonds at 4% during the low-rate period. If comparable financing now costs 8%, replacing the debt can sharply increase annual interest expense even if the company’s total borrowings remain unchanged.
S&P Global Ratings says near-term maturities have become more manageable for U.S. nonfinancial companies overall, but pressure is less evenly distributed. Debt rated B-minus and below rises more quickly and reaches an earlier maturity peak in 2028, while the broader corporate maturity wall peaks in 2029.
Strong Borrowers and Weak Borrowers Face Different Markets
Investment-grade companies generally enter this environment with stronger cash flows, better access to capital and lower credit spreads. Demand for their bonds also remains significant. U.S. investment-grade issuance reached a record $164 billion in August 2026, showing that well-rated companies can still raise substantial amounts even as Treasury yields increase.
The picture becomes less comfortable farther down the credit spectrum. Recent market data cited by the Financial Times showed spreads on CCC-rated or lower corporate debt reaching about 10.53 percentage points above comparable government securities. Default activity among weaker borrowers has also increased during 2026.
S&P Global Ratings identifies media and entertainment and healthcare among sectors with particularly large amounts of B-minus or lower debt maturing over the next two years. Telecommunications also has significant CCC/C-rated maturities.
What Should Investors Watch on the Balance Sheet?
Credit ratings offer a starting point, but investors can learn more by examining a company’s financial statements. Several indicators deserve attention when refinancing costs are rising.
- Debt-to-EBITDA shows how large borrowings are relative to operating earnings.
- Interest coverage indicates how comfortably earnings can meet interest payments.
- Free cash flow shows whether the business generates cash after normal operating and investment needs.
- Debt maturity schedules reveal how much financing must be replaced soon.
- Cash reserves and unused credit facilities indicate how much financial flexibility remains.
Higher rates do not automatically create a corporate debt crisis. PIMCO recently argued that most U.S. investment-grade and high-yield borrowers appear capable of absorbing higher refinancing costs, while CCC-rated companies remain considerably more exposed.
That distinction matters for investors. The end of ultra-cheap financing will probably hurt companies unevenly. Businesses with strong cash flow and manageable maturities can adapt. Those combining weak earnings, heavy leverage and near-term refinancing needs have far less room for error.
