Marsh Re, the global reinsurance broker, says the cyber reinsurance market is entering a period in which buyers have materially more choice, with the market moving away from standard, off-the-shelf solutions towards more tailored structures.
According to Marsh Re’s Global Specialties 2026 Market Update, the increased range of reinsurance options comes as cedants reassess their cyber exposures against a backdrop of faster-moving threats, growing concerns around artificial intelligence (AI) and the potential for greater accumulation risk.
James Boyce, CEO, Global Specialties, Cyber at Marsh Re and author of the report, stated that the cyber reinsurance market has expanded the range of structures available to buyers. Boyce highlights the placement of the first combined property/cyber catastrophe protection and the introduction of three new Risk XL covers during the year as examples of how the market is developing beyond traditional solutions.
The report says buyers are reassessing their net risk positions and reinsurance strategies as AI accelerates the speed at which cyber threats can develop. Marsh Re notes that some cedents are looking to increase the proportion of risk they cede, while others are adding more event-specific protection to their existing programmes.
Marsh Re explains that AI is compressing threat timelines significantly. According to the report, the mean time-to-exploit has fallen from 745 days in 2020 to hours in 2026. The company says the primary effect is an increase in the speed and frequency of threats, rather than a fundamentally different loss profile, while organisations using AI defensively can gain an advantage.
The development is also prompting greater scrutiny of whether existing cyber reinsurance programmes provide sufficient protection. Marsh Re adds that buyers are examining their attachment points, coverage and programme structures more closely as they consider how much risk to retain and how much to transfer to the reinsurance market.
Geographic diversification is another factor highlighted by Marsh Re. The company says portfolio construction is becoming increasingly influenced by geographic strategy, with US claims development extending from 3.7 years to 7.8 years. In Marsh Re’s assessment, this makes international diversification more significant when considering cyber portfolios.
At the same time, the report points to continued underlying demand in European cyber markets. Marsh Re says European markets are recording close to 10% premium growth in 2026 despite double-digit rate reductions, indicating that demand is continuing even as pricing conditions soften.
The report also points to growing interest in hard retrocession structures for cyber, which Marsh Re says is helping broaden the capacity available to the market. According to the company, reinsurers generated approximately US$3.4 billion from cyber quota shares between 2018 and 2025, while non-proportional treaties have recorded low-single-digit loss ratios.
Marsh Re says these results indicate that the cyber reinsurance market remains fundamentally sound, despite the uncertainty created by emerging technologies and changing threat patterns. The wider specialty market, according to the report’s executive summary, remains healthy, with dedicated reinsurer capital continuing to grow and supporting expansion across most global specialty classes.
For cyber buyers, the combination of additional capacity, new structures and changing perceptions of risk means the current market provides more scope to consider how programmes are constructed rather than focusing solely on price. Marsh Re says closer collaboration, more considered structuring and a detailed understanding of clients’ risks are increasingly important as buyers assess their options.
The company states that the broader specialty market is being shaped by geopolitical uncertainty, emerging technology risk and sustained claims pressure, with conditions differing between classes and geographies. In cyber, Marsh Re’s analysis suggests that the availability of more specialised reinsurance structures is giving buyers additional ways to respond to changes in their risk profiles.
Marsh Re concludes that the decisions being made during the current market cycle around programme structure, reinsurance partners and risk strategy could become increasingly important if market conditions change. For cyber buyers in particular, the company’s analysis points to a market where reinsurance is no longer limited to conventional solutions, giving cedents more options as they consider how best to manage emerging and evolving cyber exposures.
