Group Disability Insurance Heads Into a Countercyclical Claims Turn

Group disability new premium fell 15% in the first quarter of 2025 and stayed down 3% to 6% through the third, even as LIMRA projects U.S. employment growth below 1% annually through 2028 (LIMRA, Q1 2025; LIMRA, 2026).

That combination shrinks the insured payroll base at the same time disability incidence, historically countercyclical, tends to climb as labor markets soften. The reserve exposure sits on claims already open, not on the business not yet sold.

Key Takeaways

• $3.0 billion of workplace disability new premium through nine months of 2025, down 5% year over year, with the top 10 carriers writing 74% of it. A shrinking new-business pool concentrated on fewer books.
• Below 1% annual employment growth is LIMRA's projection for 2026 through 2028, against an unemployment rate already at 4.9% in 2025. Group disability prices per $100 of covered payroll, so that is close to a flat exposure base.
• A -0.88 coefficient links medical-improvement claim terminations to the unemployment rate, against -0.73 for work-based terminations, evidence a weak job market erodes return-to-work even after medical recovery.
• 9% of new long-term disability claims are mental or nervous disorders, the segment whose 24-month contractual limitation is the live legislative target in H.R. 3758.
• Long-term disability fell 16% in Q1 and 6% in Q3, lagging short-term disability in every quarter reported. The product with the longest reserve tail is the one contracting fastest.

An Exposure Base That Stopped Growing Before the Downturn Arrived

Group short-term and long-term disability premium is priced per $100 of covered payroll, so the insured exposure base expands only as fast as the employer groups underneath it add headcount and raise wages. The U.S. Bureau of Labor Statistics projects total employment growing a cumulative 3.1% from 2024 to 2034, adding 5.2 million jobs, against 13.0% over 2014 to 2024 (BLS, 2025).

LIMRA sharpens that into a nearer-term figure: annual employment growth below 1% from 2026 through 2028, alongside unemployment already at 4.9% in 2025. For a line whose growth mechanics assume a steadily expanding covered population, that is a flat exposure base rather than a slowing one.

The sales data already shows the strain, and the first-quarter drop landed before the sub-1% growth window had even begun. Nine-month volume totaled $3.0 billion, down 5% year over year, with the top 10 carriers writing 74% of new premium (LIMRA, Q3 2025).

What complicates a simple payroll read is that LIMRA does not forecast in-force premium falling in step. The same outlook projects short- and long-term disability in-force growth staying near recent norms while life in-force growth falls below its historical average. Carriers can hold in-force premium up through persistency and rate action on the existing block, which puts the claims-side pressure on the 2027 renewal cycle rather than on new-business underwriting.

Why the Termination Rate Is the Assumption That Moves

Disability claim incidence does not move independently of the labor market, and it does not move in the direction intuition suggests. Research on the 2001 and 2008-09 recessions found Social Security Disability Insurance applications and awards are countercyclical, with claiming rising as unemployment rises despite little evidence that severe disability itself becomes more common (NBER Working Paper 19672; RAND WR-1088). The mechanism is behavioral: a worker with an impairment faces a lower opportunity cost of filing once the job is gone.

Group long-term disability runs an analogous version with a lag. RGA's review of 2008-09 found new claim submissions dipped first, then rose and stayed elevated for years (RGA, 2020). A triangle built on 2021-2024 experience will not anticipate that shape.

The larger reserve exposure is duration, not incidence. Group LTD claim reserves are built from company-specific continuance and termination tables rather than a statutory morbidity basis, since group business is reserved off carrier experience studies rather than the individual-market 2013 IDI Valuation Table (American Academy of Actuaries, 2016). The assumption most exposed to a softening labor market is therefore the one an internal study is slowest to detect, because it is fitted to a period when return-to-work options were plentiful.

Work on SSDI terminations found post-termination earnings negatively correlated with unemployment for every termination reason, with medical-improvement terminations more sensitive at -0.88 than work-based terminations at -0.73 (SSA Social Security Bulletin, 2011). The arithmetic runs one way: a lower expected termination rate lengthens projected claim duration, which raises the present value of expected future benefits on every open claim without a single new incidence event.

Book mix decides how hard that bites. BLS puts healthcare and social assistance at 8.4% decade growth and information at 6.5% while manufacturing and much of retail sit below the 3.1% average, and the flat-headcount segments are the ones generating the layoffs.

The 24-Month Governor Is Under Pressure From Both Sides

Mental and nervous disorders account for 9% of new long-term disability claims in the most recent Integrated Benefits Institute benchmarking, behind musculoskeletal at 26%, cancer at 15% and injuries at 11% (CDA/IBI, 2024 data). That sits well below the roughly 40% share Canadian carriers reported across 2023 to 2025, a gap reflecting plan design and claim coding as much as morbidity, but the trend direction is the same in both markets.

Most group LTD contracts cap mental-health and self-reported-symptom benefits at 24 months, a limitation that has functioned for decades as the actuarial governor on that category's tail duration. The Workers' Disability Benefits Parity Act of 2025 (H.R. 3758), introduced in June 2025, would bar disability plans from applying limitations to mental-health or substance-use claims more restrictive than those applied to physical conditions. It has not been enacted, and it arrives alongside the suspended 2024 mental health parity rule.

Medical cost trend pushes on the same duration channel from the other side. LIMRA projects an 8% increase in employer health care costs for 2026 absent plan design changes, and the Milliman Medical Index put per-person employer cost growth at 7.9%, reaching $8,460. Costlier and harder-to-access care lengthens the interval between onset and medical clearance, which raises the share of short-term disability claims converting to LTD once STD benefits exhaust.

Stop-loss underwriters are meeting a parallel version of the same trend problem in premium growth decoupling from claim severity. Group disability's version runs through duration rather than severity, and it lands on the assumption a carrier holds flat because the new-business line is shrinking.
