Cyber Reinsurance Market Sees Capacity Surge, Even As U.S. Premium Volume Declines
The global cyber reinsurance market experienced unprecedented capacity growth with approximately $250 million in new non-proportional coverage entering the market in the first half of 2025, even as U.S. direct cyber insurance premiums written declined for the first time in 2024, according to a new cyber reinsurance market update by Lockton Re.
The cyber insurance sector continues its softening trajectory, with average premium rates declining between 5% and 15% in the first six months of 2025, depending on sector, geography and loss history.
The steepest reductions occurred in the mid-market segment where competition remains most intense, while less mature territories with lower cyber insurance adoption saw more modest decreases due to limited competition and available data.
In the U.S., cyber insurance direct premiums written declined to $7.1 billion in 2024, from $7.2 billion in 2023, according to A.M. Best data cited in the report.
Despite the premium declines, market dynamics are shifting in favor of cyber insurance buyers. Some companies have retained the cost savings, while others have used the reduced rates to purchase higher coverage limits, particularly in the mid-market and large corporate segments, according to the report.
First-time cyber insurance buyers are increasing, especially outside the United States, driven by heightened awareness of cyber risks following recent high-profile attacks, Lockton Re said.
The coverage landscape is also evolving, with insurers offering reduced deductibles, broader contingent business interruption protection extending beyond IT providers, and new modules for reputational harm and regulatory response. This represents a shift toward modular, tailored products rather than standardized policies, Lockton Re noted.
However, the improving conditions for buyers come with trade-offs. While premium volume declined, AM Best data showed that U.S. cyber insurance loss ratios increased by more than seven percentage points to 48.8% in 2024 from 41.6% the previous year, indicating growing claims pressure on insurers.
Challenges and Opportunities Reshape Risk Landscape
Recent ransomware attacks across diverse sectors — including major UK retailers, U.S. insurers and education service providers, and Korean telecommunications firms — have highlighted persistent vulnerabilities, particularly in third-party supplier systems, according to the report.
The attacks have generated renewed interest in cyber insurance from uninsured companies and those with inadequate coverage, driving demand among first-time buyers, Lockton Re said. For reinsurers, these events reinforce the continued focus on supply chain resilience, cyber hygiene practices, and coverage clarity.
Artificial intelligence presents both new challenges and opportunities for the sector. Threat actors are leveraging AI to conduct more sophisticated attacks and create increasingly convincing fraud.
Simultaneously, insurers are developing coverage products to protect against AI-related liabilities, including algorithmic errors, model hallucinations, and autonomous system failures. While still a niche market, early adopters include AI developers and large corporations implementing AI models across various business contexts.
Market Structure Evolves Amid Growing Capacity
The influx of new reinsurance capacity has fundamentally altered market dynamics, with supply outstripping demand in the short term, according to the report.
New entrants include both fresh entities with capital to deploy and established markets new to cyber coverage. This abundance of capacity has empowered cedants to become more demanding regarding financial security, economic terms, and contract conditions.
Incumbent reinsurers face the risk of replacement if pricing or strategic approaches become misaligned with cedant expectations. Some established cedants have shown increased comfort with their attritional loss ratios and are consequently retaining larger net positions or not renewing coverage layers that have failed to demonstrate value, Lockton Re said.
The insurance-linked securities market is gaining traction, with appetite for cyber ILS and industry loss warranties (ILW) growing steadily in the first half of 2025.
Increasing comfort with the Cyber Industry Loss Index created by PERILS and CyberAcuView, which underpins nearly half-a-billion dollars in ILW and catastrophe bond limits, is drawing broader investor interest from pension funds to hedge funds, the report said.
