Small US mutual insurers are looking to accelerate commercial lines growth as they seek to reduce the risks created by concentrated books of business.
The shift could bring additional carrier appetite to commercial accounts placed through independent agents, which remain the dominant distribution channel among mutuals when measured by company count. It also reflects a broader push by locally focused carriers to diversify without giving up the community ties that have underpinned their businesses for generations.
Tom Troy (pictured), CEO of The Mutual Group, said: “Concentration of risk is a top-of-mind issue for mutuals. They're wise to continue to stay focused on that because, as we've seen, catastrophes are not isolated to coastal areas. Catastrophes can occur in pretty much every state in the US, and they do.”
The Mutual Group is a member-based insurance services platform that provides mutual carriers with long-term capital, scale and operational capabilities spanning underwriting, claims, technology and corporate services, while allowing members to retain their independence, governance and brand.
Many mutuals operate in a single state, part of a state or a small group of states; this local focus can strengthen underwriting knowledge and customer relationships, but it can also leave a carrier heavily exposed when severe weather strikes its core territory.
Diversifying product mix is therefore becoming one of the primary ways mutuals are managing that exposure, said Troy. “In the course of the last year, what I've heard is more mutuals talking about how they want to continue to grow their commercial products at a bit of a faster pace than their personal lines products,” Troy said.
The movement is especially relevant to mutuals whose roots are in personal lines or farm insurance. Farm products have historically combined commercial exposures from agricultural operations with homes and personal vehicles located on the same property. As carriers’ approach to diversification has matured, Troy said many have concluded that they need a stronger balance between personal and commercial business.
However, any product expansion comes with execution costs. New offerings can be expensive to develop and launch, while legacy systems can complicate implementation and pricing. mutuals are increasingly weighing the type and pace of technology investment needed to support customers and distribution partners without allowing modernization costs to flow unchecked into premiums.
Smaller carriers may lack the expense-ratio advantages of national insurers, but Troy argued that they retain a powerful counterweight: close knowledge of their markets and long-standing relationships with agents and policyholders.
“They have multigenerational relationships with the agents who have distributed their products for sometimes over 100 years, and they have multigenerational relationships with customers who have responded with loyalty in a manner that I think is very unique,” he noted.
Independent agents are more prevalent in the mutual sector than premium-based market views may suggest. Independent agencies placed 62% of all U.S. P&C premium in 2025 — up from 61.5% in 2024 — and wrote 87.7% of commercial-lines premium, according to the Big "I" 2026 Market Share Report.
Separately, the 2024 Agency Universe Study (Big "I"/Future One, conducted by Zeldis Research) put the number of independent P&C agencies in the US at roughly 39,000, with the average agency holding appointments with 17 carriers.
If mutuals follow through on plans to grow commercial products faster than personal lines, independent agents could gain more options for accounts that fit a carrier’s local expertise and underwriting appetite. The opportunity is likely to emerge through existing agency relationships, rather than through a wholesale reshaping of mutual distribution.
Those relationships may help mutuals test products and identify coverage gaps. The pace of expansion, however, will depend on carriers’ pricing, technology and claims capabilities.
For Troy, the mutual structure supports that longer horizon. Without quarterly shareholder reporting, mutuals can make investments with long-term capital needs in mind. Many are more than a century old, and some have operated for over 200 years.
“Small mutuals have been here for a very long time, and I think small mutuals will be here for a long time into the future,” Troy said.
Here are some practical takeaways for agents evaluating where this trend creates room to move:
