Commercial P&C insurance has been riding on the back of a hard market. However, insurance premium increases have slowed. At the same time, insurance carriers have benefited from improving loss ratios, and capacity is starting to stabilize thanks to new market entrants.

Global commercial insurance prices rose by only 9% in the 2023, which was the sixth consecutive quarter of slowing premium increases for most P&C lines.

According to the Insurance Information Institute (III), US insurance industry net premiums written totaled $1.28 trillion in 2022, with premiums recorded by property/casualty insurers accounting for 51% and premiums by health/life insurers accounting for 49%.

P&C insurance includes auto, homeowners and commercial insurance. Net premiums written for the sector totaled $652.8 bn last year. Meanwhile, the life/annuity insurance sector includes annuities, accident and health, and life insurance with net premiums for the sector totaling $240 bn.

P&C carriers face a combination of complex and fast-evolving macroeconomic and industry trends, which interact with each other and the industry’s entrenched ways of working (see about P&C Insurance Claims Landscape).

The US insurance industry employed 2.9 mn people, according to the US Department of Labor. Of those, 1.7 mn worked for insurance companies, including life and health insurers (962,500 workers), P/C insurers (665,900 workers), and reinsurers (27,300 workers). The remaining 1.2 mn worked for insurance agencies, brokers, and other insurance-related enterprises.

The net combined ratio for the P&C insurance industry was 102.4, with underwriting losses for personal lines partially offset by underwriting gains for commercial lines.

The P&C insurance sector has long struggled with challenging fundamentals. Intense price competition erodes value across the board, and globally, only a small number of sector leaders turn a profit. Commoditization of both personal and commercial lines products, particularly in the small commercial segment, continues unabated.
