US Credit Outlook Stays Benign Despite AI Risks and High Rates: Fitch
Fitch Ratings predicts a stable US credit outlook but warns that high interest rates and AI funding needs could pressure lower-rated borrowers.
The US credit outlook is expected to remain broadly benign even as the country navigates tighter funding conditions. According to Fitch Ratings, while the general landscape is stable, the combination of "higher-for-longer" interest rates and the massive capital requirements for artificial intelligence (AI) investments could create significant hurdles for lower-rated borrowers and sectors sensitive to interest rate hikes.
Economic Growth Forecasts on the Rise
Despite the potential risks, Fitch has shown optimism regarding the US economy's trajectory. The agency has raised its economic growth forecasts for 2026 and 2027 by 0.2 percentage points each, now projecting a growth rate of 2.1 per cent. This upward revision is attributed to two primary factors: resilient consumer spending and a surge in private investments driven by the AI boom.
Looking ahead at fixed investment, Fitch expects growth of 4.8 per cent in 2026 and 4.6 per cent in 2027, signaling continued confidence in corporate expansion.
The Interest Rate Pressure Cooker
While growth looks promising, the cost of borrowing remains a critical concern. Fitch anticipates that the Federal Reserve will raise interest rates to 4.25 per cent in December and maintain that level through 2027. This sustained high-rate environment will put immense pressure on borrowers who must refinance their existing debt at much higher costs.
This follows the Fed's most recent policy decision to hold the benchmark interest rate at 3.75-4 per cent, as officials continue to monitor persistently high inflation levels.
The AI Paradox: Growth Driver vs. Financial Risk
Artificial Intelligence is currently a double-edged sword for the US financial system. On one hand, it is a massive engine for growth; IT-related private investment jumped approximately 18 per cent year-on-year in the second quarter of 2026.
On the other hand, the sheer scale of borrowing required to fund AI capital expenditure is reshaping funding conditions. Large technology companies are increasing their corporate borrowing, contributing to a 24.5 per cent year-on-year increase in corporate bond issuance during the first nine months of 2026. Overall, US fixed-income issuance rose by 10.4 per cent in the same period.
Potential AI Pitfalls
Fitch warns that the AI gold rush faces potential headwinds:
- Intensifying Competition: A crowded market could erode the pricing power of AI service providers.
- Open-Weight Models: The availability of cheaper, open-weight AI models may force companies to rethink their expensive capital expenditure plans over the next one to three years.
In a stark warning, Fitch noted that an "adverse AI equity-correction scenario" could trigger a US recession, potentially leading to a 0.6 per cent decline in GDP by 2027.
Warning Signs for Lower-Rated Borrowers
While investment-grade bond spreads are hovering near multi-year lows, the situation is far bleaker for riskier debt. Yields on CCC-rated debt have widened by roughly 480 basis points since the start of the year, highlighting the struggle of lower-rated entities.
The agency also pointed to alarming default trends:
- Private Credit: The US private-credit default rate hit a record 6.3 per cent in the 12 months ending September 2026.
- Leveraged Loans: Defaults in this sector are expected to climb toward the lower end of the 4.5-5 per cent forecast range by the end of the year.
Ultimately, Fitch's analysis suggests a divided credit market: a resilient core supported by AI and consumer strength, and a vulnerable fringe struggling under the weight of high interest rates and refinancing costs.
