AI Infrastructure Spending Pushes US Tech Bond Spreads to Two-Decade High
TREE NEWS reports: US investment-grade technology companies are now paying the highest premium over the broader market to borrow in the bond market since 2003, as the race to build AI data centers and computing infrastructure drives an unprecedented surge in debt issuance. The average spread on US tech investment-grade bonds has climbed to a three-year high, even as spreads for the overall investment-grade market remain relatively stable, widening the funding cost gap between the tech sector and other issuers.
The development underscores a fundamental shift in how bond investors are pricing the credit risk of the companies leading the AI revolution. Giants including Google, Microsoft, Meta, Amazon, and Oracle are tapping debt markets to finance hundreds of billions of dollars in data centers, chips, and power infrastructure. But as issuance swells, investors are demanding higher yields to compensate for potential credit risk and supply pressure.
Market Implications
The widening spreads signal that the bond market is beginning to differentiate between the AI haves and have-nots. While the overall investment-grade market remains calm, the tech sector’s borrowing costs are rising, which could squeeze profit margins and slow the pace of infrastructure buildout if financing becomes prohibitively expensive.
Credit default swap (CDS) markets are also flashing warning signs. The cost of insuring against default on Alphabet’s debt has nearly doubled over the past year, and Oracle’s CDS quotes have risen notably. The notional value of AI-related CDS trades has surged from less than $7 billion a year ago to nearly $30 billion, indicating that investors are actively hedging exposure to the AI supply chain. Nvidia’s five-year CDS spread has widened to 141.5 basis points.
“The CDS market moves do not imply imminent defaults, but they show investors are adding hedges and keeping a higher alert on the solvency and future funding needs of AI-linked companies,” said one credit analyst.
Tech firms are trying to diversify their funding sources across currencies and markets. BNP Paribas forecasts that net supply of euro-denominated investment-grade corporate bonds will grow 83% to €192 billion ($214 billion) in 2027, up from €105 billion this year. However, increased access to different markets does not mean unlimited absorption capacity. As issuance rises, investors are demanding higher risk compensation for new bonds.
AI borrowers are relatively insensitive to funding costs because they need massive capital to maintain competitive advantage. But when more companies simultaneously enter the bond market, investor capital and risk tolerance have limits. Tech firms may have to offer higher yields to complete financing.
Key Takeaways for Investors
- Watch credit spreads closely: The widening gap between tech and non-tech investment-grade spreads could signal a broader repricing of credit risk in the AI ecosystem. Keep an eye on Oracle, which has the highest spread relative to the index in history at 2.8x.
- Hedging activity is rising: The surge in AI-related CDS trading suggests institutional investors are increasingly concerned about the debt sustainability of AI infrastructure builders. This could lead to higher volatility in tech bonds and related equities.
- Funding costs matter for equity valuations: As debt becomes more expensive, the return on AI investments will be scrutinized more closely. Companies with strong free cash flow and lower leverage may outperform those heavily reliant on debt markets.
- Diversification is key: The AI trade is no longer just about equity upside; it now carries credit risk. Investors should assess their exposure to tech bonds and CDS, and consider hedging strategies if they are heavily weighted toward AI leaders.
The AI arms race is reshaping corporate finance. While the technology holds transformative potential, the cost of financing it is rising, and bond investors are beginning to demand a premium for the risk. How companies balance investment returns against debt burdens will be a key driver of market performance in the years ahead.
