P&C insurers race to modernize as digital expectations rise

Modernization is the floor now

The baseline has shifted: in P&C insurance, digital transformation is no longer a modernization goal, it is the minimum operating standard. Carriers that still treat core upgrades, data unification, and workflow digitization as side projects are not just running older software, they are accepting slower decisions, clunkier service, and more expensive change.

That matters because the industry’s pain is no longer theoretical. Modern platforms now have to support the full journey, from quote to bind to billing to claims, without forcing customers or employees to hop across disconnected systems. If the core cannot keep pace with that expectation, every other initiative becomes harder to execute.

Why the old core is breaking down

The bluntest argument comes from the core systems themselves. McKinsey’s 2025 view is that systems built for a slower, paper-driven P&C model are no longer fit for purpose. That is not a stylistic complaint. It is a warning that legacy architecture creates operational friction, slows agility, and drives up maintenance costs just when carriers need to move faster.

The better option is no longer hypothetical. McKinsey also says modern SaaS platforms with cloud architectures, continuous updates, and deep ecosystem integration are viable at scale. That changes the buyer’s checklist. The question is not whether a system can process policies or claims at all, but whether it can absorb continuous change, connect cleanly to adjacent tools, and keep moving without constant disruption.

There is also a long memory behind this shift. McKinsey’s earlier work in 2016 found that top P&C digital leaders were already growing revenue 1.5 times as fast as the rest of the field and running combined ratios four percentage points lower. The gap between leaders and laggards has been visible for years. What changed is that the rest of the market can no longer pretend it is optional.

What customers are already expecting

Customer behavior has caught up with the technology story. J.D. Power’s 2024 U.S. Claims Digital Experience Study put overall satisfaction with the digital claims process at 871 out of 1,000, up 17 points from 2023. That is a meaningful gain, and it shows that better digital execution is being noticed.

The same study also found that digital channels have surpassed phone-based communication as the most satisfying way to submit a new claim. That is the kind of detail carriers should take seriously. People are no longer comparing insurers only with other insurers. They are comparing them with the smooth digital experiences they get in banking, retail, and anywhere else a modern service journey is supposed to just work.

The catch is that experience quality is still uneven. Insurers made an average of 6.75 mobile app updates in 2023, up from 5.72 in 2022, which shows that carriers are iterating more aggressively. But the service gap remains glaring: 84% of claimants said their insurer provides an easy digital communication process, yet only 39% said their insurer always responded in a timely fashion to emails and text messages. Easy to use is not the same as dependable, and customers notice the difference quickly.

The operating model has to change, not just the front end

This is where a lot of transformation programs still stumble. Moving a form online is not the same as redesigning the business around faster decision-making and more responsive service. If the workflow underneath is still stitched together with manual handoffs, the customer experience will feel modern for a moment and then stall.

Carriers that get this right tend to focus on a few practical priorities:

• unify policy, billing, and claims data so teams are not working from different versions of the truth
• build workflows that connect underwriting, service, and claims instead of isolating them in separate silos
• favor platforms that support faster releases, configurable changes, and cleaner integration with external tools
• treat digital communication as a service promise, not just a convenience feature
• use automation to reduce repetitive work so staff can spend time on judgment-heavy cases

That is why vendors such as Guidewire and Duck Creek sit at the center of so many core replacement conversations. The platform itself is only part of the story. The real test is whether it gives carriers room to change without turning every product tweak, regulatory adjustment, or claims workflow update into a full-scale IT event.

Capital strength does not cancel margin pressure

The industry is not modernizing from a position of collapse. The NAIC’s 2024 annual P&C report showed policyholders’ surplus rising 6.5% to more than $1.1 trillion. That is a healthy capital base, and it matters because it gives carriers room to invest.

But the operating environment is still tight. Triple-I and Milliman forecast 2025 net written premium growth at 6.8%, down 2.0 points from 2024 and the lowest since 2020. They also projected an industry-wide net combined ratio of 99.3, which leaves very little cushion. In other words, the industry still has money, but it does not have much slack.

The homeowners side makes the pressure even more obvious. Triple-I said the January 2025 Los Angeles wildfires contributed significantly to losses, and the Q1 2025 homeowners loss ratio was the worst first quarter in more than 15 years. That is the hard reality behind the software debate: climate volatility is not an abstract risk anymore, and older systems make it harder to price, respond, and recover quickly.

The next wave is already here

EY’s 2025 Global Insurance Outlook adds another layer to the problem. The industry is dealing with climate and cybersecurity risks, accelerating GenAI and agentic AI, increased regulatory scrutiny, and shifting customer behavior. At the same time, expanding data volumes are creating new opportunities in risk assessment, pricing, and partnerships.

That combination is exactly why the old modernization playbook feels too timid. Carriers do not just need cleaner back-office plumbing. They need systems that can support new data flows, tighter compliance demands, faster product changes, and more automated service without breaking every time the market shifts.

The bottom line is simple. The insurers that keep treating core upgrades, data unification, and workflow digitization as optional will spend more time defending legacy friction than competing on service. The ones that move now will be better positioned to deliver faster quotes, quicker claims, and more connected journeys, which is what the market now expects by default.
