Insurers Doubled Premiums in a Decade. Their AI Spend Didn't Move the Expense Ratio.

Insurance direct written premiums have doubled over the past ten years. Expense ratios, over that same decade of heavy AI and digital investment, fell by just one percentage point. That’s the gap Bain’s July 20 insurance outlook puts a number on, and it’s a clean read on where a decade of technology spend actually landed.

Bain finds 2025 delivered strong premium growth and improved profitability from rate increases, plus a relatively benign year for catastrophe losses — yet insurance stocks still underperformed broader equity markets, and Bain frames the gains as cyclical, not structural. Three structural problems sit underneath: an affordability crisis as P&C coverage grows less accessible after a multiyear hard market; the technology gap above; and value-chain fragmentation, as reinsurers, securitization vehicles, and alternative asset managers capture more value than traditional carriers. The detail that sharpens the productivity story: hiring is down nearly 50% since 2022, which means headcount reduction — not a demonstrated output gain — is where the AI investment shows up most clearly so far.

The gap isn’t unique to insurance. In a candid HITEC 2026 interview, Oracle Hospitality’s own VP of OPERA Cloud Strategy admits AI’s ROI remains unproven even as Oracle has already built roughly 50 AI agents — a vendor conceding that agent supply is outrunning any demonstrated payoff, in a completely different industry. Set against that is BCG’s more bullish “decision agents” framing, which cites potential working-capital reductions of up to 30% and EBITDA uplift of two to four points from board-level AI deployment. The optimistic case is out there; Bain’s insurance numbers are evidence the realized return still lags it.

For companies weighing where their own AI investment sits on this spectrum, insurance is instructive precisely because it has a longer measurement window than most industries. Whichever framework a company reaches for — Bain’s cost-of-risk levers or BCG’s decision agents — the real test isn’t a pilot’s success story. It’s whether the spend eventually shows up in an actual financial ratio.
