Inflation Continues
to Drive Up Consumers’ Insurance Costs

By William Nibbelin, Senior Research Actuary, Triple-I

Insurance is priced to reflect the underlying risk of every policy. When more claims are filed and the average amount paid of those claims increases, insurance becomes more expensive. A measure of underwriting profitability for insurance carriers is the combined ratio calculated as losses and expense divided by earned premium plus operating expenses divided by written premium. A combined ratio over 100 represents an underwriting loss. When expected losses increase, an insurance carrier must increase premiums by raising rates to maintain a combined ratio under 100.

Commercial auto insurance has recorded a net combined ratio over 100 nine times out of 10 between 2014 and 2023, and, according to the latest forecasting report by Triple-I and Milliman, continues to worsen in 2024. According to the Triple-I Issues Brief, personal auto insurance has had a net combined ratio over 100 for the past three years, with a 2023 net written premium (NWP) growth of 14.3 percent, which was the highest in over 15 years.

From 2014 through 2023 economic and social inflation added $118.9 billion to $137.2 billion in auto liability losses and defense and cost containment (DCC) expenses. This represents 9.9 percent to 11.5 percent of the $1.2 trillion in net losses and DCC for the period and an increase of 24 percent to 31 percent from the previous analysis on years 2013 through 2022.

A new study – “Increasing Inflation on Auto Liability Insurance – Impact as of Year-end 2023” – is the fourth installment of research on the impact of economic and social inflation on insurer costs and claim payouts. Compared to the prior study, Commercial Auto Liability loss and DCC is 20.7 percent to 27.0 percent ($43 billion to $56 billion) higher due to increasing inflation. Personal auto liability loss and DCC is 7.7 percent to 8.2 percent ($76 billion to $81 billion) higher from increasing inflation.

Key Takeaways

  • The compound annual impact of increasing inflation ranges from 2.2 percent to 2.9 percent for commercial auto liability, which is higher than the personal auto liability estimate of 0.7 percent. However, the impact of increasing inflation from a dollar perspective is much higher for personal auto liability compared to commercial auto liability. This is due, in part, to the underlying size of the line of business.
  • Frequency of auto liability claims per $100 million GDP for 2023 is unchanged for commercial auto liability and lower for personal auto liability compared to 2020, when frequency dropped at the onset of the COVID-19 pandemic for both lines.
  • Severity of auto liability claims continues to increase year over year and has increased more than 70 percent from 2014 to 2023 for both lines.

Researchers Jim Lynch, FCAS, MAAA, Dave Moore, FCAS, MAAA, LLC, Dale Porfilio, FCAS, MAAA, Triple-I’s chief insurance officer, and William Nibbelin, Triple-I’s senior research actuary used a similar methodology as prior studies. Loss development patterns were used to identify inflation for selected property/casualty lines in excess of inflation in the overall economy. The new study extends the model with annual statement data through year-end 2023.

Commercial Auto Liability

The prior study indicated claim severity (size of losses) had risen 72 percent overall from 2013 to 2022, with the median annual increase at 6.3 percent. The new study indicates an additional annual increase of 6.6 percent from 2022 to 2023. The report compares the compound annual growth rate of 6.6 percent from 2014 through 2023 to the compound annual increase in the consumer price index (CPI) of 2.8 percent during this same time. With a flat frequency trend combined with an increasing severity trend in recent years for commercial auto liability, this comparison calls out the higher inflation faced by insurers beyond just general inflation trends.

Personal Auto Liability

While replacement costs remain flat to negative providing relief to personal auto physical damage, personal auto liability represents approximately 60 percent of the overall personal auto line. Similar to commercial auto liability – but slightly lower – claim severity for personal auto liability has increased at a compound annual rate of 6.3 percent from 2014 through 2023. However, unlike commercial auto liability, the frequency for personal auto liability has declined slightly in 2022 and 2023, with 85 claims per $100 million GDP in 2023 compared to 90 in 2022 and 100 in 2021.

Limitation of industry data

The report relies on industry data as reported by insurers to the National Association of Insurance Carriers (NAIC) and made available through different reporting suppliers, such as S&P Global Market Intelligence. As such, different individual inflationary elements – whether economic, social, or otherwise – cannot be determined using the underlying actuarial methodologies.

However, like prior studies the bulk of increasing inflation before 2020 is attributed to social inflation, while social inflation and economic inflation dominate increasing inflation together beginning in 2020.

Triple-I continues to foster a research-based conversation around social inflation as part of legal system abuse. For an overview of the topic and other helpful resources about its potential impact on insurers, policyholders, and the economy, check out our knowledge hub.

Improved Commercial Auto Underwriting Profitability Expected After Years of Struggle

The commercial auto insurance line has struggled to achieve underwriting profitability for years, even before the inflationary conditions that have been affecting property/casualty lines more recently. This trend has been accompanied by steady growth in net written premiums (NWP).

This weakness in underwriting profitability has been driven by several causes, according to a new Triple-I Issues Brief. One is the fact that vehicles – both commercial vehicles and personal vehicles they collide with – have become increasingly expensive to repair, thanks to new materials and increased reliance on sensors and computer systems designed to make driving more comfortable and safer. This well-established trend has been exacerbated by supply-chain disruptions during COVID-19 and continuing inflation in the pandemic’s aftermath.

Distracted driving and litigation trends also have played a role.

However, Triple-I sees some light on the horizon for commercial auto in terms of the line’s net combined ratio – a standard measure of underwriting profitability calculated by dividing the sum of claim-related losses and expenses by earned premium. A ratio under 100 indicates a profit and one above 100 indicates a loss.

As the chart below shows, the estimated 2024 net combined ratio for commercial auto insurance has improved slightly since 2023, and further improvement is expected over the next two years.

These projected improvements are based on an expectation of continued premium growth – due more to aggressive premium rate increase than to increased exposure – as the rate of insured losses levels off.

Louisiana Is Least Affordable State for Personal Auto Coverage Across the South and U.S.

Despite strong income growth that has helped improve personal auto insurance affordability in Louisiana, the state remains the least affordable among its Southern neighbors and the rest of the United States, according to the Insurance Research Council (IRC).

In 2022, the average annual premium expenditure per vehicle for auto insurance in Louisiana was $1,588, which is nearly 40 percent above the national average and nearly double that of the lowest-cost Southern state of North Carolina ($840), the IRC report says. Louisiana’s spending accounted for 2.67 percent of the median household income in the state.  

Florida’s average annual premium expenditures, at $1,625, exceed Louisiana’s, but the state is slightly more affordable; Florida’s higher median income results in a lower expenditure share of income (2.49 percent).  The Sunshine State is not included in the IRC report because it is the only no-fault jurisdiction among the Southern states, a fact that skews some comparisons.

All the Southern states had median household income below the overall U.S. figure, contributing to affordability challenges in the region as a whole. This was especially true for Mississippi, where the median income was 35 percent below the U.S. median.

In addition to low average household incomes, Louisiana’s affordability issues stem from such cost drivers as a higher tendency to file injury claims when an accident occurs, a high rate of underinsured motorists, and a high rate of claim litigation. Previous IRC claim research has pointed to high rates of attorney involvement in auto injury claims in the state.

In addition, Louisiana received the second-lowest score in a 2019 survey of businesses regarding the fairness of states’ litigation landscapes conducted by the U.S. Chamber of Commerce. It also is a perennial member of the “Judicial Hellholes” list published by the American Tort Reform Association (ATRA).

Personal Lines Underwriting Results Improve, Reducing Gap With Commercial Lines

The U.S. property and casualty insurance industry experienced better-than-expected economic and underwriting results in the first half of 2024, according to the latest forecasting report by Triple-I and Milliman.  The report was released during a members-only webinar on Oct. 10.

The industry’s estimated net combined ratio of 99.4 represented a 2.3-points year-over-year improvement, with commercial lines continuing to outperform personal lines. Combined ratio is a standard measure of underwriting profitability, in which a result below 100 represents a profit and one above 100 represents a loss. 

Much of the overall underwriting gain was due to growth in personal lines net premiums written. Commercial lines underwriting profitability remained mostly flat.

“The ongoing performance gap between personal and commercial lines remains, but that gap is closing,” said Triple-I Chief Insurance Officer Dale Porfilio. “The significant rate increases necessary to offset inflationary pressures on losses are driving the improved results in personal auto and homeowners. With that said, the impact of natural catastrophes such as Hurricanes Helene and Milton threaten the improved homeowners results and are a significant source of uncertainty.”

During the webinar Q&A period, Porfilio provided insight on the potential impact of Hurricane Milton on the Triple-I 2024 net combined ratio forecast during the Q&A portion. One key figure regarding potential catastrophe losses is the impact on the 2024 net combined ratio forecast of adding one additional billion dollars of catastrophe losses. Each additional billion dollars of catastrophe losses is an impact of one tenth of a percent on the forecast.

Triple-I has loaded an estimate for catastrophe losses for the second half of 2024 based on historical experience, trends, economic projections, etc. prior to Milton, so there is no expectation of needing to add $30 billion to $40 billion – the recent estimate published by Gallagher Re.

If there was a need to add an additional $30 billion in catastrophe losses, that would be a +3.0-point impact on the forecast.

The net combined ratio for homeowners insurance of 104.9 was a six-point improvement over first-half 2023.  The line is expected to achieve underwriting profitability in 2026, with continued double-digit growth in net written premiums expected in 2025.   

Personal auto’s net combined ratio of 100 is 4.9 points better than 2023. The line’s 2024 net written premium growth rate of 14.5 percent is the highest in over 15 years. 

Jason B. Kurtz – a principal and consulting actuary at Milliman – elaborated on profitability concerns within commercial lines. Commercial lines 2024 net combined ratio remained relatively flat at 97.1 percent. Improvements in commercial property, commercial multi-peril, and workers compensation were offset by continued deterioration in commercial auto and general liability.

“Commercial auto expectations are worsening and continue to remain unprofitable through at least 2026,” he said. “General liability has worsened and is expected to be unprofitable through 2026.”

Michel Léonard, Triple-I’s chief economist and data scientist, said P&C replacement costs are expected to overtake overall inflation in 2025.

“P&C carriers benefited from a ‘grace period’ over a few quarters during which replacement costs were increasing at a slower pace than overall inflation,” Dr. Léonard said. “That won’t be the case in 2025.”

Actuarial Studies Advance Discussion
on Bias, Modeling, and A.I.

The Casualty Actuarial Society (CAS) has added to its growing body of research to help actuaries detect and address potential bias in property/casualty insurance pricing with four new reports. The latest reports explore different aspects of unintentional bias and offer forward-looking solutions.

The first  –A Practical Guide to Navigating Fairness in Insurance Pricing” – addresses regulatory concerns about how the industry’s increased use of models, machine learning, and artificial intelligence (AI) may contribute to or amplify unfair discrimination. It provides actuaries with information and tools to proactively consider fairness in their modeling process and navigate this new regulatory landscape.

The second new paper — Regulatory Perspectives on Algorithmic Bias and Unfair Discrimination” – presents the findings of a survey of state insurance commissioners that was designed to better understand their concerns about discrimination. The survey found that, of the 10 insurance departments that responded, most are concerned about the issue but few are actively investigating it. Most said they believe the burden should be on the insurers to detect and test their models for potential algorithmic bias.

The third paper –Balancing Risk Assessment and Social Fairness: An Auto Telematics Case Study” – explores the possibility of using telematics and usage-based insurance technologies to reduce dependence on sensitive information when pricing insurance. Actuaries commonly rely on demographic factors, such as age and gender, when deciding insurance premiums. However, some people regard that approach as an unfair use of personal information. The CAS analysis found that telematics variables –such as miles driven, hard braking, hard acceleration, and days of the week driven – significantly reduce the need to include age, sex, and marital status in the claim frequency and severity models.

Finally, the fourth paper – “Comparison of Regulatory Framework for Non-Discriminatory AI Usage in Insurance” – provides an overview of the evolving regulatory landscape for the use of AI in the insurance industry across the United States, the European Union, China, and Canada. The paper compares regulatory approaches in those jurisdictions, emphasizing the importance of transparency, traceability, governance, risk management, testing, documentation, and accountability to ensure non-discriminatory AI use. It underscores the necessity for actuaries to stay informed about these regulatory trends to comply with regulations and manage risks effectively in their professional practice.

There is no place for unfair discrimination in today’s insurance marketplace. In addition to being fundamentally unfair, to discriminate on the basis of race, religion, ethnicity, sexual orientation – or any factor that doesn’t directly affect the risk being insured – would simply be bad business in today’s diverse society.  Algorithms and AI hold great promise for ensuring equitable risk-based pricing, and insurers and actuaries are uniquely positioned to lead the public conversation to help ensure these tools don’t introduce or amplify biases.

Despite Improvements, Louisiana Is Still
Least Affordable State for Auto Insurance

Max Dorfman, Research Writer, Triple-I

Louisiana’s personal auto insurance affordability improved to 2.67 percent of median household income in 2022 – down from 2.93 percent in 2020 – but it retains the dubious distinction of being the least affordable state, Triple-I’s chief insurance officer told the Louisiana House Insurance Committee in recent testimony.

Dale Porfilio – who also is president of the Insurance Research Council (IRC) – said that by nearly every metric the state’s insurance cost drivers are well above the national average:

  • Accident frequency – Louisiana is 16 percent higher than the national average;
  • Repair cost severity – Louisiana is 9 percent higher;
  • Injury claim relative frequency – Two out of every four property damage claims (when cars hit cars) in Louisiana result in bodily injury claims (49 percent), twice the one out of every four (25 percent) across all states;
  • Medical utilization – Louisiana is 47 percent higher;
  • Attorney involvement – Louisiana is 24 percent higher;
  • Underinsured motorists – At-fault drivers in Louisiana have insufficient liability insurance limits in over 35 percent of multi-car accidents, over twice the 16 percent U.S. average; and
  • Claims litigation – Litigation over personal auto claims in Louisiana is more than twice the national average, surpassed only by Florida.

Porfilio noted that for auto insurance affordability to improve, overall expected losses will need to be reduced. Legislation to reduce one or more of these key cost drivers would be helpful, Porfilio said.

As Triple-I and IRC previously reported, the combination of high insurance expenditures and low median income make Louisiana a difficult state in which to lower costs. The frequency of hurricanes hitting the state increases homeowners insurance costs, and the high cost of reinsurance has contributed to the Louisiana’s insurance woes.

In fact, in 2020 and 2021, in the wake of Hurricane Laura and Hurricane Ida, insurers paid out more than $23 billion in insured losses from over 800,000 claims filed.

While Louisiana policymakers were confident a $45 million fund approved in February 2023 to encourage insurers to write property insurance business in the state would help stabilize the market, insurance commissioner Jim Donelon recognized that the approved grants are only the first step toward reducing homeowners’ insurance rates.

As Porfilio’s testimony demonstrated – and the market has dictated – more work is needed to lower costs for consumers and insurers in Louisiana.

Georgia Is Among the Least Affordable States for Auto Insurance

By Max Dorfman, Research Writer, Triple-I

Georgia’s personal auto insurance affordability has significantly worsened over the past decade and a half, making it one of the least affordable states, according to a new report by the Insurance Research Council (IRC) – a division of The Institutes, like Triple-I.

The study, Personal Auto Insurance Affordability in Georgia, ranks the state 47th in terms of auto insurance affordability. Only four other states – Louisiana, Florida, Mississippi, and New York – are less affordable. In 2006, Georgia was the 27th most affordable state.

Personal auto insurance expenditures in Georgia accounted for two percent of the median household income in 2022 (the latest year for which expenditure data is available). This is compared with 1.5 percent nationally.

Key findings:

  • From the mid-2000s through 2014, Georgians spent about the same on auto insurance as other Americans. In the mid-2010s, however, auto insurance expenditures in Georgia began escalating. Between 2014 and 2022, auto insurance spending in Georgia grew 5.6 percent annualized, compared with 3.3 percent in the country overall and faster than in any other state. In 2022, Georgia’s average expenditure of $1,347 was 20 percent higher than the U.S. average.
  • Affordability issues in Georgia’s auto insurance market stem from multiple factors — many of which have been faced by the rest of the country — including economic inflation, rising replacement costs, risky driving behavior, and legal system abuse. However, several key cost drivers are higher in Georgia, including propensity to file injury claims, number of underinsured motorists, and claim litigation.
  • Auto insurance litigation is a growing concern in Georgia, especially as tort reform in neighboring states may be pushing law firms in those states to seek opportunities elsewhere. Georgia has experienced elevated attorney advertising rates, particularly in television advertising.

“Uninsured and underinsured motorists are both a symptom and a cause of affordability issues,” said Dale Porfilio, FCAS, MAAA, president of the IRC. “When affordability deteriorates, whether from increasing costs or slower income growth, increasing numbers of motorists may choose to lower the policy limits or to forgo the mandated insurance completely.”

Porfilio, who is also Chief Insurance Officer of Triple-I, noted that the resulting need for drivers to purchase uninsured motorist (UM) and underinsured motorist (UIM) protection further increases average insurance expenditures.

“Both the UM and UIM rates are higher than average in Georgia,” he said. “The UIM rate is especially high in the state: Georgia’s UIM rate has been increasing steadily and was the third-highest rate in the country in 2022.”

Report: No-Fault Reforms Improved Michigan’s Personal Auto Insurance Affordability

By Max Dorfman, Research Writer, Triple-I

Michigan personal auto insurance affordability improved markedly after enacting substantial auto insurance reform in 2019, according to a new report by the Insurance Research Council (IRC) – like the Triple-I, a division of The Institutes

The study, Personal Auto Insurance Affordability in Michigan, found that personal auto insurance expenditures accounted for 1.9 percent of the median household income in Michigan in 2022 (the last year the data is available), a decline of half-a-percent from the pre-reform peak. Michigan’s expenditure share remains higher than the percentage in the overall U.S. and forty-four other states.

Other key findings from the report include:

  • Before the reforms, Michigan drivers were required to purchase unlimited personal injury protection (PIP) coverage; in comparison, the second highest mandated amount of PIP coverage was $50,000 in New York. The unlimited medical benefits and other features, such as attendant care benefits and no medical fee schedule, led to Michigan’s extremely high average auto injury claim severity, which has been the primary cost driver in the state.
  • In 2022, Michigan households spent $1,319 to insure each vehicle, nearly 20 percent above the national average. However, in the years since reform, expenditures have fallen in Michigan while increasing in almost every other state. From 2019 to 2022, the average expenditure for auto insurance in Michigan fell 12 percent compared with an increase of five percent in the U.S. overall.
  • Uninsured and underinsured motorists are both a symptom and cause of affordability issues. In 2019, Michigan had the highest rate of uninsured drivers in the country, with more than one in four motorists lacking the required liability coverage. The uninsured motorist rate in Michigan dropped by 5 percent between 2020 and 2022.

“Efforts to improve auto insurance affordability in Michigan must begin with the underlying cost drivers: injury claim severity and litigation,” said Dale Porfilio, FCAS, MAAA, president of the IRC. “The average amount paid per auto claim for auto injury insurance is dramatically higher in Michigan, more than double the U.S. average and one and a half times the second highest state.”

Porfilio, who is also Chief Insurance Officer of the Insurance Information Institute (Triple-I), noted that the 2022 affordability data does not fully reflect many recent countrywide challenges to affordability, such as economic inflation, higher replacement costs, legal system abuse, and deteriorating driving behavior. “However, the movement of several key indicators illustrate the positive effect of the Michigan policymakers’ efforts to improve affordability in their state.”

NCIGF Moves Ahead
to Support Insurers

By Max Dorfman, Research Writer, Triple-I

For the last 35 years, the National Conference of Insurance Guaranty Funds (NCIGF) – an organization dedicated to serving 55 property/casualty state guaranty funds – has provided operational support; communications, education, and outreach; as well as public policy management for these organizations.

State guaranty funds make up a privately funded, nonprofit state-based national system that pays covered claims up to a state’s legally allowable limits, protecting policyholders if their insurer becomes insolvent. There are 55 such funds because some states have more than one.

“All states have a property/casualty guaranty association, and some have a workers compensation guaranty association,” NCIGF President and CEO Roger Schmelzer explained in a recent “Executive Exchange” with Triple-I CEO Sean Kevelighan.

“We’re not claims payers,” Schmelzer said, “We try to do things for our members that they wouldn’t be doing for themselves or that it’s better to be doing in one place.”

For nearly five decades, the guaranty fund system has paid out more than $35 billion to cover claims against about 600 insolvencies.

“Through the years, the system has successfully met every challenge that’s come its way, and has been instrumental in supporting the insurance promise,” Schmelzer said.

NCIGF recently announced its updated organizational strategy, which focuses on:

  • Pre-liquidation planning with regulators and receivers,
  • Understanding and preparing for the changing landscape in insolvencies, and
  • Seeking shared solutions to common problems among state associations.

“We want to understand better the trends and factors that could lead to insolvency,” Schmelzer said. “Then we want to do everything we can with our members, working through our educational arm, to make sure members are prepared for whatever those trends might bring.”

Insurance Underwriting
and Economic Analysis: “Art and Science”

By Lewis Nibbelin, Guest Blogger for Triple-I

Home and auto insurance premium rates have been a topic of considerable public discussion as rising replacement costs and other factors – from climate-related losses to fraud and legal system abuse – have driven rates up and, in some states, crimped availability and affordability of coverage.

It’s important for policyholders and policymakers to understand the role of economic conditions and trends in setting rates.  Jennifer Kyung, Property and Casualty Chief Underwriting Officer at USAA, opens a window into the complex world of underwriting and economics in a recent episode of Triple-I’s All Eyes on Economics podcast.

Kyung told podcast host and Triple-I Chief Economist and Data Scientist Dr. Michel Léonard that economic analysis “is critical to us in underwriting and as we manage our plan.” She described economics as “part of our muscle memory as underwriters” – adding that the economic uncertainty of recent years reinforces the need for underwriters to have “a very agile mindset.”

Underwriting and economics are “a little bit art and science,” representing a balancing act between sophisticated data analytics and creative problem-solving.

“When we think about sales and premiums for homeowners, we may look at things like mortgage rates or new home starts to indicate how the market is going,” Kyung said. “In auto, we might look at new vehicle sales or auto loan rates. These, in combination, help us look at macro-economic trends and the environment and how that might interplay with our volume projections. That helps us with financial planning, as well as operational planning.”

“It’s really critical to keep these on the forefront on an ongoing basis throughout the year,” she said, “so we can adjust as needed…. As our results come in, this gives context to the results.”

Through continual analyses of external market conditions and the internal quality and growth of your business, Kyung said, underwriters “can manage and mitigate some of the volatility and risk for our organizations.”

A tool she recommends for evaluating economic indicators is Triple-I’s replacement cost indices, which track the evolution of replacement costs throughout time across various lines of insurance and geographic regions. These indices enable insurers to synthesize raw economic data and insurance market trends, providing an auxiliary framework to bolster financial and operational planning.

Kyung said Triple-I offers additional insight into “local flavor,” or “understanding what the emerging issues are…related to the local environment,” through such tools as Issues Briefs and Insurance Economics Profilers. Recent supply-chain disruptions have accentuated the relationship between local and global economies, revealing the importance of employing local economic analytics to interpretations of broader insurance market patterns.

Such fusions can help facilitate efficient planning in the face of shifts in the insurance landscape.
