Reinsurance capacity
Reinsurance capacity is the amount of coverage reinsurers are willing and able to provide to insurers. It reflects the capital available in the market to absorb risk.
Capacity refers to the maximum limit of risk that reinsurers can accept, driven by the amount of capital they hold and their appetite for a given line of business or region. At the market level, capacity expands and contracts as capital flows in or out, which in turn influences pricing and how easily primary insurers can find the coverage they need.
Capacity matters because it shapes market conditions. When capacity is abundant, reinsurance is easier to buy and prices tend to soften; when capacity is scarce, often after large catastrophe losses, terms tighten and prices harden. Adequate capacity allows primary insurers to keep writing new business and to offer higher limits with confidence.
New or complex exposures, such as cyber, space, and advanced technology risks, can be especially constrained by limited capacity because reinsurers have less loss history on which to price them. RiskCube Re, described as the first AI-native reinsurance company, aims to provide capacity for MGAs and carriers underwriting exactly these emerging and complex risks.
