Fitch Sees Fed Hiking to 4.25% in December, Flags CCC Blowout

Fitch Ratings expects the Federal Reserve to raise its policy rate to 4.25% in December and hold it there through 2027, according to a Fitch Wire commentary published Tuesday alongside its fourth-quarter US credit brief. The agency simultaneously lifted its US growth forecasts for 2026 and 2027 by 0.2 percentage point to 2.1% each. It still describes the overall US credit outlook as broadly benign, even as higher-for-longer rates and AI-related funding needs press the weakest borrowers.

Context — why the December Fed call matters now

Fitch's December call fits the view that the Fed is still on a hiking path, which supports front-end Treasury yields and the US dollar and argues against any near-term easing. That matters for anyone holding duration or floating-rate exposure into year-end.

The report's own comparison is the split inside credit rather than the headline outlook. Investment-grade spreads remain near multi-year lows, while yields on CCC-rated debt, the lowest rung of high yield, have widened by about 480 basis points since the start of the year. The same macro backdrop is producing two different credit outcomes.

Growth is being revised up, not down. Fitch lifted its 2026 and 2027 US GDP forecasts by 0.2 point each to 2.1%, citing resilient consumer spending and AI-driven private investment. Fixed investment is forecast to grow 4.8% this year and 4.6% next year.

Funding supply is the catalyst chain. Fitch said US fixed-income issuance rose around 10% year on year in the first nine months of 2026, while corporate bond issuance climbed around 25%, driven partly by hyperscaler AI borrowing. Heavy Treasury supply plus hyperscaler deals raises the risk that new issues need bigger concessions even where credit quality holds up.

Data — what the numbers show

The headline figures sit at opposite ends of the credit spectrum. Investment-grade spreads are near multi-year lows; CCC yields have blown out by roughly 480 bps year to date. Fitch's US private credit default rate reached a record 6.3% in the 12 months to September, and the agency expects leveraged loan defaults to rise toward the low end of its 4.5% to 5.0% year-end forecast range.

Metric	Fitch figure
Fed policy rate (Dec call)	4.25%
US GDP growth 2026 / 2027	2.1% / 2.1%
Fixed investment 2026 / 2027	4.8% / 4.6%
US fixed-income issuance, 9M y/y	~+10%
Corporate bond issuance, 9M y/y	~+25%
CCC yields, YTD	~+480 bps
Private credit default rate (12M to Sep)	6.3%

On the growth side, IT-related private investment grew around 18% year on year in the second quarter. Fitch calls AI both the main growth driver and a key downside risk, warning that intensifying competition and cheaper open-weight models could weaken pricing power for AI service providers and prompt a rethink of hyperscaler capex plans over the next one to three years.

Analysis — what it means for markets and sectors

The second-order effect runs through refinancing. Fitch says a 4.25% policy rate held through 2027 will sustain pressure on borrowers who need to refinance at higher costs, and it flags housing-related sectors and lower-rated borrowers as the most exposed. That is where the record 6.3% private credit default rate and the 480 bps CCC move connect.

The AI leg cuts both ways. Fitch's adverse AI equity-correction scenario would mean a US recession, with GDP contracting 0.6% in 2027. Its sector-level AI stress test found broad resilience, with material risks concentrated in services, data centres, and telecommunications, media and technology. Data centre and TMT names therefore carry the concentrated exposure if capex plans shift.

One limitation sits inside the benign call itself. Fitch's outlook rests on consumer resilience and AI-driven investment continuing, and its own adverse scenario shows what breaks if AI equity valuations correct. The agency did not disclose the probability it assigns to that scenario.

Positioning follows the split. Investment-grade credit is priced for calm, with spreads near multi-year lows, while the CCC blowout shows the flow is discriminating hard against the weakest issuers. Heavy hyperscaler supply on top of Treasury issuance is the channel through which that discrimination could reach higher-quality new deals.

Outlook — what to watch next

Two variables dominate. The first is the Fed's December decision, which Fitch expects to deliver the hike to 4.25%. The second is the durability of hyperscaler AI spending, which Fitch says could be reconsidered over the next one to three years if competition and cheaper open-weight models erode AI service pricing power.

On levels, watch whether CCC yields extend the roughly 480 bps year-to-date widening, and whether leveraged loan defaults track toward the low end of Fitch's 4.5% to 5.0% year-end range. Both are the report's own markers for whether pressure is broadening beyond the weakest borrowers.

For equities, putting a recession scenario next to AI capex keeps the spotlight on any sign that hyperscalers are scaling back spending plans. Data centre and TMT exposure is where Fitch's stress test concentrates risk, so capex guidance is the transmission point.

Frequently Asked Questions

What does Fitch's 4.25% Fed call mean for bond investors?

It implies front-end Treasury yields stay supported and near-term easing is off the table through 2027 on Fitch's view. For credit, the more important detail is the divergence: investment-grade spreads near multi-year lows versus CCC yields up about 480 bps this year. Duration-sensitive and lower-rated holdings face the sharper refinancing pressure.

Why have CCC yields widened so much while investment-grade spreads stay tight?

Fitch's own data points to stress at the bottom of the credit stack. Its private credit default rate hit a record 6.3% in the 12 months to September, and leveraged loan defaults are expected near the low end of a 4.5% to 5.0% range. Higher-for-longer rates hit borrowers that must refinance at higher costs hardest.

What is Fitch's AI recession scenario and which sectors does it hit?

Under Fitch's adverse AI equity-correction scenario, the US falls into recession with GDP contracting 0.6% in 2027. Its sector stress test found broad resilience, with material risks concentrated in services, data centres, and telecommunications, media and technology. The trigger it names is weaker AI service pricing power prompting a hyperscaler capex rethink.

Bottom Line

Fitch still calls US credit benign overall, but its December hike call and record private credit defaults show the pressure is concentrating on the weakest borrowers.
