Fitch Ratings has revised its outlook for the US health insurance sector to “deteriorating” from “neutral,” citing policy uncertainty and increasing utilization trends.
The US non-life personal lines outlook was also adjusted to “neutral” from “improving.” Outlooks for other insurance sub-sectors remain unchanged at “neutral.”
The downgrade in the health sector reflects higher-than-expected growth in healthcare utilization and legislative developments affecting government-funded healthcare programs.
Central to Fitch’s revised assessment is the anticipated impact of the "One Big Beautiful Bill Act," which passed the House of Representatives and is now pending in the Senate. The bill includes provisions that would reduce federal Medicaid funding through several mechanisms.
Among the most significant measures are new work requirements, effective no later than year-end 2026, and more frequent eligibility determinations. These changes are expected to reduce Medicaid enrollment, thereby cutting premium revenue for insurers managing state Medicaid plans.
The House version also includes a moratorium on provider taxes, which Fitch noted could shift additional financial responsibility to state governments and further weaken an already low-margin funding model for Medicaid insurers.
The pressure on Medicaid profitability, already a key concern, is expected to continue through at least the first half of 2025, according to Fitch. Insurers operating in this space are still in the process of renegotiating payment rates with state agencies, and uncertainty around rate adequacy persists. This issue compounds the challenge of managing thin margins, particularly as medical cost trends remain unpredictable.
In addition, Fitch cited the expiration of enhanced Premium Tax Credits (PTCs) at the end of 2025 as another factor weakening the sector’s outlook. These credits support the affordability of health coverage purchased through Affordable Care Act (ACA) exchanges.
While some policy analysts had anticipated an extension to help mitigate Medicaid enrollment losses, the legislative trajectory suggests that subsidies will lapse, removing a buffer that could have helped sustain insurer revenues.
In parallel, broader utilization trends are affecting overall operating results. A recent review of US health insurers indicated that utilization levels remained elevated throughout 2024, with higher acuity observed among Medicaid populations following redetermination processes.
These shifts have put pressure on earnings, contributing to a decline in average EBITDA margins from 6.9% to 5.9% year-over-year. For insurers managing large public-sector books, the decline represents a meaningful challenge in maintaining profitability targets.
(AC) Fitch also noted some stabilization in Medicare Advantage margins heading into 2025. Updates to bid pricing appear to have better captured utilization trends, which may provide moderate relief for insurers operating in that segment. However, the gains are not expected to offset broader revenue headwinds stemming from the Medicaid and ACA markets.
Fitch also revised the US non-life personal lines outlook to “neutral,” reversing a previous improvement trend. The agency attributed the adjustment to recent California wildfire losses and slowing rate momentum in the personal auto segment due to heightened competitive pressure.
Although prior rounds of rate increases have supported profitability, Fitch observed that pricing changes are now moderating. Meanwhile, tariff-related cost pressures could further contribute to severity in both auto and homeowners’ lines.
Despite these headwinds, Fitch continues to expect underwriting profitability in the personal lines market in 2025. The personal auto combined ratio improved in 2024, aided by previous pricing actions. Homeowners’ premium levels are also trending upward in most states, partially in response to rising natural catastrophe exposures.
