AM Best: US Mutual Insurers Resilient Despite Perpetual Volatility

U.S. P/C Mutual Insurers Rely on Investment Income Amid Underwriting Challenges

U.S. property/casualty (P/C) mutual insurance companies have relied on investment income to counterbalance the weather-related challenges driving underwriting volatility, according to a new AM Best report.

The report, “US Property/Casualty Mutual Insurers Resilient Despite Perpetual Volatility,” highlights the pressures from continued inflation and severe weather-related activity in 2023, which pushed pure losses up by nearly 15% compared to the prior year. P/C mutuals recorded an underwriting loss of $36.6 billion in 2023, a 17% increase over 2022.

Despite these underwriting losses, net investment income of $23.4 billion in 2023—a 26% rise over 2022—helped offset the financial strain. However, insurers continue to face challenges from rising reinsurance costs and regulatory delays or resistance to rate increases.

“Many insurers are receiving rate increases, but there has been pushback,” said Lauren Magro, financial analyst at AM Best, noting that state insurance regulatory regimes differ in their conservatism, which can lead to delays in rate approvals and implementations.

Mutual insurers saw significant growth in gross premiums written (GPW) since 2021, spurred by rising reinsurance costs and inflationary pressures. Net premiums written (NPW) increased by nearly 13% in 2023, marking the highest premium growth in the mutual segment over the past decade.

“Insurers continue to pursue rate adequacy, with many looking to implement additional rate increases in the second half of 2024, likely continuing into 2025,” added Magro.

At the close of 2023, policyholders’ surplus for U.S. P/C mutuals was just under $400 billion, an increase from 2022, but still below 2021 levels. The change in surplus was largely driven by a recovery in the equity market, which reported unrealized capital gains of over $18 billion from 2022 to 2023.

The report also notes that over the past five years, mutual insurers’ investment portfolios have remained conservative, with bonds representing around 60% of investments annually, while stocks have constituted 19% to 23%.
