TRIPLE-I/MILLIMAN: P/C INSURANCE INDUSTRY POISED FOR GROWTH AND UNDERWRITING PROFITABILITY IN 2025 DESPITE GEOPOLITICAL AND NATURAL CATASTROPHE UNCERTAINTIES

The following information was released by the Insurance Information Institute:

The U.S. property/casualty (P/C) insurance industry is projected to grow faster than the overall economy in 2025 and is on track to achieve underwriting profitability for a second consecutive year, according to Insurance Economics and Underwriting Projections: A Forward View from the Insurance Information Institute (Triple-I) and Milliman, a collaborating partner.

The report, presented at a members-only briefing Thursday, noted cautious optimism in economic results, pending major shifts in monetary or public policy. "P/C economics and the U.S. economy have outperformed expectations in 2025," said Michel Leonard, Ph.D., CBE, chief economist and data scientist at Triple-I. "Even though the tariffs' impact is less severe than originally expected, the question remains whether the full negative impact has been avoided or simply pushed back to 2026.

"The P/C industry is benefiting from stronger-than-expected underlying growth, pushing premium volume up, and replacement costs that remain below overall inflation," Leonard added. "But ongoing risks, including tariffs, labor market softening, and persistent inflation, make the 2026 outlook especially important to monitor."

The P/C industry achieved underwriting profitability in 2024 for the first time since 2020. Profitability is expected again in 2025, though to a lesser extent.

Highlights of the Briefing

GDP is expected to grow 1.6% in 2025, below the Federal Reserve's target.

P/C underlying growth projected at 2.4%, exceeding GDP.

P/C replacement costs are projected to rise from 1.4% in 2024 to 2.2% in 2025, below overall inflation and better than January forecasts.

Interest rate cuts are expected to take about 12 months to reduce mortgage rates, with housing starts projected to accelerate in 20262027.

Homeowners 2025 net combined ratio (NCR) forecast improved from prior estimate but is still expected to be unprofitable for the year.

Personal auto 2025 NCR forecast slightly improved from prior estimates and is on track to achieve continued profitability.

General liability NCR is the only major line forecasted to stay above 100 NCR in the near term.

"Favorable second-quarter results for homeowners helped narrow the anticipated 2025 gap between personal and commercial lines performance created by the Los Angeles fires in the first quarter," said Patrick Schmid, Ph.D., chief insurance officer at Triple-I. "Net written premium growth for personal lines is expected to remain higher than commercial lines by one point in 2025, but is projected to converge by 2027."

Jason B. Kurtz, FCAS, MAAA, principal and consulting actuary at Milliman, added general liability (GL) continues to face long-term challenges.

"We see underwriting losses continuing in 2025, with the 2025 net combined ratio for GL forecast at 107.1. Direct incurred loss ratios through mid-2025 have not improved relative to 2024's poor result. Forecasted net written premium growth of 8.0% is 4.8 points above 2024 as premiums respond to recent performance," he said. "While we expect slight improvement in 2026-2027, we estimate GL combined ratios to remain above 100."

Workers' compensation remains the strongest-performing major line in the P/C industry. Preliminary 2025 results from NCCI show calendar year combined ratios in the range of 8593. Donna Glenn, chief actuary at NCCI, noted, "If this holds, it will represent 12 consecutive years of combined ratios under 100 for private carriers."
