Corporate Issuers Skip Long-Term Bonds Despite Strong Demand

Investors bid for $10 billion in 30-year notes, yet companies issue only a fraction of that amount.
Aon Inc. sold $2 billion in 30-year notes while investors ordered $10 billion. This ten-to-one oversubscription marks a peak in demand for long-dated corporate debt. GSK Plc saw similar results, with orders covering ten times the $500 million supply. This level of interest exceeds the 2026 average for high-grade US issuers. The average order size for such bonds is currently four times the supply.
Companies are reluctant to lock in high interest rates for decades. Rising global yields have made long-term borrowing expensive. Issuers prefer shorter maturities to reduce the cost of servicing debt. This strategy minimizes the burden of fixed payments in a high-rate environment. The result is a significant reduction in the supply of long-term paper.
Supply contraction limits long-term options
Only 5% of US investment-grade bonds sold in early September mature in 30 years or more. This represents $108.3 billion in debt, the lowest share since 2020. The same trend appears in European and Asian markets. The average maturity of US high-grade debt has dropped to 10.3 years. This is down from a peak of 12.4 years recorded in recent years.
Duration has also shrunk to 6.5 from 8.8 five years ago. This metric measures price sensitivity to interest rate changes. The decline reflects a strategic shift toward shorter liabilities. Issuers are avoiding the cost of extending their debt curves. This move limits the available supply for investors seeking long-term income.
Central bank policy drives yield increases
The 30-year Treasury yield rose nearly 0.5 percentage points this year. It closed at 5.37%, a post-financial crisis high. The Federal Reserve hiked rates by 0.25 percentage points. This was its first increase in three years. The Fed signaled further hikes are likely due to inflation concerns.
The European Central Bank lifted rates for the second time this year. Traders expect three more hikes by October 2027. Higher oil prices and geopolitical tensions fuel inflation fears. These factors push up borrowing costs globally. Issuers respond by shortening their debt tenors to avoid locking in high rates.
Investors face a scarcity of long-dated debt
Life insurers and pension funds need long-dated debt to match liabilities. The shortage creates a challenge for these investors. They must seek alternatives to fund future payouts. The gap between demand and supply remains wide. Portfolio managers report difficulty finding suitable long-term corporate bonds.
Hyperscalers like Alphabet and Amazon have flooded the market with long-dated debt. This crowds out other issuers and shifts investor focus. The market structure is changing as rates rise. Companies are prioritizing shorter maturities to manage costs. This dynamic reduces the availability of long-term fixed income products.
