P&C Industry Loss Reserves: The $20B Moment and What It Means for Your Agency

A Market Intelligence Report | Tague Alliance Insurance Services March 2026

---

The Headline

Year-end 2025 data is showing that the P/C insurance industry’s carried loss reserve position is more than $20 billion redundant carriermanagement — and that’s a really big deal. Let me walk you guys through what that means, why it happened, and most importantly, what it signals for your agency’s book of business heading through 2026.

Quick Primer: What Does “Reserve Redundancy” Even Mean?

Here’s the deal — when a claim comes in, carriers post a reserve. They’re essentially saying, “We think this claim will ultimately cost us X dollars.” That money sits on the balance sheet as a liability.

So let’s say they project a claim at $1 million and post a reserve for $1 million. But the claim ultimately closes at $800,000. They release that $200,000 — it flows right back into earnings. That’s reserve redundancy.

When you multiply that dynamic across millions of claims industry-wide, you get to a number like $20 billion. That’s the industry collectively having more money set aside than the claims are actually going to cost. And right now, according to Assured Research President William Wilt — a Fellow of the Casualty Actuarial Society — the estimated redundancy as of year-end 2025 is $20.7 billion. That’s 10 times bigger than the estimated redundancy at year-end 2024, which was just $2.0 billion. carriermanagement

Ten times. In one year. That’s not incremental — that’s an inflection point.

The Big Winner: Personal Auto Liability

The single biggest driver of this industry-wide swing is personal auto liability, and the numbers are dramatic. The redundancy in year-end personal auto liability reserves is now estimated at $12.0 billion, compared to $1.9 billion at year-end 2024. carriermanagement

What caused this? It’s actually kind of a classic insurance cycle story playing out in real time. Carriers went ballistic on rate increases in 2022 and 2023 — you all lived through that with your clients. Those rate increases did their job. Wilt pointed to a combination of factors — the classic case where rates shot higher in 2022 and 2023, and in 2024-2025 claims came down appreciably. carriermanagement

And here’s an interesting layer on the claims side: Wilt suspects some of it is attributable to the secular trend of more cars with advanced safety features — but much of it is from claiming behavior that has benefited auto insurers, with people being reluctant to file small to modest-sized claims. carriermanagement People got sticker shock from high premiums and started eating smaller claims rather than risk a rate hit. Net result? Carriers won on both ends — higher premiums, lower claim frequency. Mints.

Supporting that view from a broader market standpoint, AM Best reported that the U.S. P&C industry recorded its strongest performance in ten years in 2025, with the personal lines segment remaining strong and private passenger auto and homeowners lines maintaining favorable trends.

What’s Coming for Auto Rates in 2026: The Soft Market Is Here

So if you’ve been wondering why some of your personal auto clients are suddenly seeing better rates — or why carriers are getting more aggressive on quoting — now you know why.

Wilt indicates that the reserve redundancy in personal auto is signaling an “outright soft market” for personal auto insurance. And he’s direct about what comes next: “Rates will go lower in 2026. Results are too good and affordability matters too much.” carriermanagement

The data backs this up across multiple sources. Nationally, one market analysis projects a measured 1% increase in the average annual full-coverage premium in 2026, based on loss projections and the current rate environment — with car insurance costs expected to fall in 15 states. Insurify And more than half of states are expected to see car insurance rates drop in 2026, with five of the 10 largest carriers expected to lower their rates. Aftermarket Matters

The commercial insurance market broadly entered a pronounced soft phase in Q4 2025, with premiums rising just 0.2% on average — a dramatic deceleration from 1.6% in Q3. Nine lines of business recorded premium decreases, including commercial property, cyber, and workers’ compensation. Risk & Insurance

Point is — the hard market correction that hammered your clients for three years is unwinding. That’s good news for retention. That’s also a signal that competition is coming, and you need to be ready for it.

The Trouble Spot: Other Liability (Occurrence)

Now here’s where the story gets more nuanced, because not every line is telling the same story.

Other liability-occurrence — think general liability, personal umbrella, commercial GL — is still showing a meaningful reserve deficiency. While the level of deficiency has improved from $15.0 billion at year-end 2024 to $12.5 billion at year-end 2025, it still carries the biggest reserve deficiency of any line analyzed. carriermanagement

And the S&P GMI team provided some color on why this line is so stubborn: the U.S. insurance industry saw $7.3 billion of adverse loss development in the other liability (occurrence) line during 2025, with more than half coming from recent accident years. More than $3 billion of that was reserve strengthening in accident years 2022 and 2023 alone. Carrier Management

So the carriers are still playing catch-up on prior years while the claims environment keeps evolving.

The root cause? Social inflation — and it’s not slowing down. The number of so-called “nuclear verdicts” — awards exceeding $10 million — more than quadrupled between 2020 and 2024, while the median value of these verdicts more than doubled in the same period. By 2024, more than 130 nuclear verdicts were recorded, representing a 50% increase from the previous year. Risk & Insurance

In 2016, 58% of U.S. consumers believed that damage awards were too low. By 2025, that figure had jumped to 76%. Risk & Insurance That’s a massive shift in jury-pool mentality in under a decade — and it’s reshaping the loss environment in ways that actuaries are still trying to get their arms around.

I think this is the single most important long-term trend for agencies writing commercial liability to understand. Your clients’ GL and umbrella rates aren’t going to soften the way personal auto is. Wilt’s call on this: rates for other liability occurrence are likely to “remain elevated as adverse prior period development comes through on accident years 2021-2023” — calling it a “gradual recalibration” rather than outright softening. carriermanagement

The Lines in the Middle: Workers’ Comp, Commercial Auto, Property

Workers’ Comp is in an interesting spot. Reserves are still showing redundancy, which has kept the market competitive and rates low — but the wind is shifting. The workers’ compensation market remained profitable in early 2025, but insurer net profit margins are narrowing due to a decrease in reserve redundancy. While the sector maintained a combined ratio averaging 91% from 2015 to 2023, reserve benefits are showing signs of weakening. Insurance Business America Rising labor costs and healthcare inflation are creating headwinds. I’d watch this one carefully in 2026.

Commercial Auto continues to be the problem child of the industry. The commercial auto sector has now generated an underwriting loss for the 14th consecutive year. In 2024, there were $4.9 billion in total underwriting losses — worse than the 11-year average annual underwriting loss of approximately $2.9 billion. Smartchoiceagents Social inflation is the culprit here too, particularly in trucking and larger fleet operations. Don’t expect meaningful rate relief in commercial auto anytime soon.

Commercial Property is a different story — the market has broadly softened. Abundant carrier capacity and exceptionally favorable loss ratios enabled insurers to price more competitively through late 2025, with large account commercial property premiums recording their first decline since the last soft market in Q4 2017. Risk & Insurance

The Macro Picture

Stepping back, the overall industry health is strong — AM Best projects the combined ratio improved to 95.0 in 2025, from 97.1 in 2024 ReinsuranceNe.ws, and net premiums written grew a solid 6.1% for the year. The industry is well-capitalized, and capital is flowing back in, which is fueling the competitive environment we’re all starting to feel.

But AM Best is also flashing a yellow light for 2026. Lower net premium growth in 2026 for commercial lines is expected to lead to a higher combined ratio of 96.3 compared with 95.8 in 2025 — and AM Best predicts the overall P/C industry combined ratio will increase 1.9 points to 96.9. Insurance Journal So the industry is still healthy, but the margin compression trend is underway.

One wildcard in all of this: tariffs. Several reports noted that rising material costs could push auto physical damage and commercial property loss trends higher in 2026. If rising claims costs from tariffs are passed on to drivers via higher premiums, analysts project an additional 3 percentage point increase could be added to personal auto forecasts. Insurify Something to watch.

What This Means for Your Agency

Landing the plane here — here’s the “so what” for independent agencies:

Personal Auto: The hard market is over. Competition is ramping up fast. This is your window to re-shop, retain, and grow. Use the soft market to add value for clients — don’t just pocket the wins. Shop proactively and make sure your clients know it was you who got them a better deal.

Commercial GL & Umbrella: Rates are staying elevated — and they should be. If clients are pushing back on GL and umbrella pricing, walk them through what’s driving it: nuclear verdicts, social inflation, real reserve deficits in those lines. Education builds trust and retention.

Commercial Auto: Still a tough market for a reason. Be selective, submit clean accounts, and set realistic expectations with clients. There’s no cavalry coming on rate relief here.

Workers’ Comp: Enjoy the favorable market while it lasts, but don’t get caught flat-footed when the reserve cushion runs out. The pricing cycle will turn.

Commercial Property: A genuine buyer’s market right now for well-maintained, low-cat-exposure accounts. Great time to negotiate expanded coverage and better terms.

The broader theme across all of this is that the industry is moving from a monolithic hard or soft market cycle into something more fragmented by line. Wilt put it well: “The once monolithic pricing cycle is morphing into a series of more distinct, but still correlated market cycles.” carriermanagement That means our job as advisors gets more nuanced — and our value to clients goes up, because they need a guide who understands which line is going which direction and why.
