SKN | ING Links AI Investment and Corporate Bond Supply to Rising Long-Dated Yields

Key Takeaways:

• ING estimates that artificial intelligence accounts for about 20% of the forces behind the recent rise in long-dated yields.
• The bank identifies increased corporate bond issuance to finance AI-related capital spending as an important transmission channel into longer-term rates.
• U.S. corporate issuance has reached $878 billion in 2026, with technology, media and telecommunications companies accounting for $330 billion.
• ING’s analysis separates the AI effect from broader drivers, assigning roughly 50% to inflation and 30% to fiscal-deficit concerns.

ING is linking part of the recent rise in long-dated bond yields to the financing requirements of the artificial-intelligence investment cycle. In its latest rates and credit analysis, the bank estimates that AI accounts for approximately 20% of the forces influencing long-end yields, primarily through stronger productivity expectations and a surge in corporate borrowing to fund technology investment.

ING Identifies Corporate Financing as the Key AI Transmission Channel

For ING, the most important connection between AI and bond yields is not simply higher technology spending. It is the way companies are financing that spending. The bank notes that U.S. corporate bond issuance has reached $878 billion year to date, already exceeding the full-year totals recorded in every year from 2021 through 2024. Issuance is also 54% above the same period last year, with technology, media and telecommunications companies accounting for approximately $330 billion.

ING says AI-focused companies have increasingly chosen longer-dated bonds rather than bank borrowing to obtain the scale and duration required for their capital expenditure programs. That distinction matters for the bank’s rates analysis because longer corporate borrowing places additional supply pressure toward the back end of the yield curve.

AI Is Increasing the Demand for Long-Term Funding

ING’s research highlights that issuance with maturities of 17 years or longer has become the largest maturity bucket in 2026, at approximately $235 billion. By comparison, issuance in the 9-to-12-year range stands at $219 billion. The bank argues that the shift toward longer maturities is an important factor contributing to pressure on long-dated rates.

ING also contrasts the increase in corporate borrowing with bank lending. While bank lending has increased, the growth has been considerably smaller than the rise in bond issuance. The result, in ING’s assessment, is that the financing burden is being pushed more heavily into capital markets and longer-duration debt.

ING Separates AI From the Larger Inflation and Fiscal Story

Importantly, ING does not attribute the rise in long-dated yields primarily to AI. Its analysis assigns approximately 50% to inflation, 30% to the fiscal-deficit narrative and 20% to the AI-related component. This makes the bank’s interpretation more nuanced than a simple claim that technology investment is driving rates higher.

ING identifies inflation as the largest influence, while fiscal deficits remain a persistent source of pressure through government borrowing requirements. Within the AI component, the bank estimates that productivity represents the majority of the effect, while AI-related issuance represents a smaller portion.

Why ING’s Analysis Matters for the Bank’s Clients

For sophisticated wealth holders, ING’s analysis highlights a structural interaction between technology investment, corporate financing and fixed-income markets. AI-related growth can support economic productivity while simultaneously increasing the supply of long-duration corporate debt. Those forces can coexist, creating different implications for equity, credit and bond portfolios.

For ING, the analysis also reinforces why long-end rates cannot be assessed through central-bank policy alone. Corporate funding behaviour, fiscal supply and inflation dynamics are increasingly relevant to the bank’s assessment of duration risk. With AI investment expected to remain capital intensive, ING sees elevated issuance as a factor that could persist beyond 2026 rather than a temporary market distortion.

The broader message is measured: AI is contributing to higher long-dated yields, but it is one component of a much larger rates environment. For investors managing significant fixed-income exposure, ING’s framework places the emphasis on understanding how inflation, fiscal supply and private-sector borrowing interact across the long end of the curve.
