WSIA Marketplace Opens Amid Record Growth: What E&S Players Need to Know

As the WSIA Marketplace kicks off in San Diego, E&S underwriters face a market where they must move quickly to take advantage of ample opportunities.

Against the backdrop of a tough commercial insurance market, excess and surplus (E&S) lines continue to thrive. For the sixth consecutive year, E&S premiums have increased by at least double digits, with U.S. domestic E&S direct premiums written increasing 13% year-on-year to $98.2 billion for the full-year 2024, according to the latest S&P Global Market Intelligence report.

E&S premiums accounted for 9.5% of the country’s total direct premiums written in 2024, up 0.4% from the previous year and 3.8% in 2019. In particular, commercial property, directors and officers liability and workers’ compensation are the lines that have performed strongest. “Shared and layered property and management liability lines are performing better than ground-up property, long-tail liabilities and health care risk profiles,” said David Haas, president, global casualty, CNA Insurance.

“This may also be a function of the sheer level of capital being deployed in those areas tied back to relatively tame storm seasons. But, in general, we’re seeing sharp increases in the automobile-driven business as well as tough products risks, which is enabling the market to strike better relativity and program structures where the hope is that long-term performance will be better.”

As claims continue to escalate and juries award outsized verdicts and settlements, exacerbated by funded litigation, the traditional market has responded by increasing rates by double digits or, in some cases, even greater, and tightening limits, and terms and conditions, or pulling coverage altogether, affording an opportunity for E&S providers to step in.

Given its freedom of rate and form, its nimbleness and ability to adapt solutions to meet often unique, hard to insure and unaffordable risks, and its significant investment over the last five years to handle the flow of business, the E&S market is well positioned to capitalize on such opportunities.

“The world continues to become increasingly complex and the risk is evolving more quickly than ever before,” said Brady Kelley, CEO and president of the Wholesale and Specialty Insurance Association (WSIA). “The E&S market is built as the safety valve of the insurance industry and will meet that demand and adapt to the risk appetite of the standard market.”

Market Dislocations

Yet, there also remain several key market dislocations. Chief among them are umbrella and excess liability, catastrophe-exposed property, construction, commercial auto and health care.

“There is an ongoing theme which is liability businesses are continuing to struggle,” said Erich Bublitz, SVP and head of AmTrust excess and surplus. “The obvious area of concern is auto, both in the primary and excess layer.

“But the challenges are not limited to just auto. Contractor liability specifically in construction defect states are also seeing profitability struggles — driven by long-tail, challenging legal environments and inflationary pressures.”

As regards umbrella and excess liability, most impacted are those classes affected by social inflation where the underlying $1 million in underlying general liability limits is under greater pressure from attorneys getting involved in cases both more quickly and more often.

Consequentially, insurers are having to revise their strategies and coverage positions as regards where they are comfortable to deploy available capacity within an excess coverage tower. “The biggest challenge in the E&S market continues to be centered on the casualty space, driven by factors like social inflation and litigation funding,” said Kevin Doyle, CEO of Risk Placement Services.

“Additional challenges include driving top talent to the sector, the increased frequency of catastrophes, emerging technology and economic uncertainty.”

While casualty claims litigation continues to be a big challenge for the E&S market, improved claims management strategies focused on nuclear verdicts and raising broader awareness on the topic are helping to drive tort reform and legislative changes in several states, notably Florida and Georgia, while Congress is also making a big push to avoid litigation system abuse. Insurers and brokers are also partnering to better control claims litigation.

“Reform of casualty claims litigation has been two-fold,” said Sam Baig, president of brokerage at Amwins.

“First, it has been about raising the bar for what’s considered negligence if you take the right precautions and, secondly, full disclosure of funded litigation agreements that are in place when going to court to try and sway juries.”

Another challenge is keeping pace with demand and volume of submissions. That requires E&S providers to be quicker and more responsive than ever.

“E&S providers are both having to move quicker to meet these increased and ever-changing demands and risk profiles, as well as developing and broadening their expertise in these areas,” said Jason Conkin, executive vice president, E&S casualty at Arch Insurance. “But if they are set up right, they can turn that challenge into an opportunity.”

Key Opportunities

Despite a tough auto market, this presents a huge opportunity for surplus insurers experienced at writing the risk. As traditional insurers continue to back away from the risk, that’s only going to present further opportunities for their E&S counterparts. Another key opportunity for E&S is cyber.

While the market is generally soft due to increased competition, there are several emerging risks such as supply chain and generative AI that they should be looking to capitalize on. E&S providers should also leverage new tech such as AI and automation to drive greater operational efficiency.

“Those E&S providers that embrace technology and AI and invest in product development and innovation can improve their efficiencies and be faster, better and more responsive to their customers’ needs,” said Baig.

“They are already starting to do that from an underwriting standpoint, for example, to prioritize submission flow, manage workloads and identify new opportunities.”

To support its impressive growth to date, the E&S market needs to recruit more talent. This is being driven by WSIA.

“The biggest challenge for the E&S insurance market is continuing to develop new talent as many of our experienced professionals approach retirement age,” said Lynanne St Denis, head of wholesale property and casualty, Navigators, a brand of The Hartford.

While college risk management programs are expanding and awareness of rewarding insurance careers has grown, there is still plenty of progress to be made to ensure that our industry is attracting students and even experienced professionals exploring a career change.”

David Blades, associate director, A.M. Best, said: “Surplus lines companies, especially those with multi-faceted distribution platforms, have expressed confidence that their distributors will continue to provide more than ample opportunities to write the lines of coverage and risk classes that they have identified as most desirable. The competitiveness impacting certain lines and risk classes are what will ultimately determine how good those opportunities are, and how much companies can take advantage of them to satisfy growth desires.” &
