The global insurance market entered 2026 with conditions continuing to favour buyers, but growing geopolitical instability and emerging risk concentrations are beginning to reshape underwriting behaviour, according to Aon’s Q1 2026 Global Insurance Market Insights report.
While capacity remains broadly available across most major lines, insurers are becoming increasingly selective about the risks they are prepared to support.
Organisations with strong risk controls, credible resilience strategies and high-quality data are gaining a clear advantage as underwriters sharpen their focus on exposure accumulation, supply chain vulnerability and geopolitical disruption.
The report highlights the ongoing conflict in the Middle East as a major source of uncertainty for insurers globally. Underwriting scrutiny has intensified as insurers reassess exposures, review policy wordings and adjust pricing positions in response to rapidly shifting claims scenarios.
Aon notes insurance markets are increasingly acting as an early warning signal for broader economic and operational disruption, often moving ahead of capital markets or visible business impacts.
Against that backdrop, the report argues organisations should rethink insurance purchasing as a strategic resilience exercise rather than a pure cost-management function.
Buyers are being encouraged to stress-test program structures, reassess risk retention levels and explore alternatives such as captives, parametric insurance and multi-year placements. The report also flags artificial intelligence infrastructure as a potentially significant future market pressure point.
Massive planned investment in global data centres and digital infrastructure is expected to create growing demand for insurance and risk transfer capacity, potentially challenging the traditional market’s ability to absorb future exposure growth.
Aon's A1 2026 Global Insurance Market Overview paints a picture of a market offering buyers more flexibility for now, but with warning signs beginning to emerge beneath the surface.
For organisations navigating geopolitical instability, climate volatility, supply chain exposure and fast-evolving technology risks, the findings provide an important snapshot of where underwriting appetite, pricing and risk transfer strategies may head next; and why proactive engagement with insurers has become increasingly critical during a period of rapid global uncertainty.
