Rising interest rates generally benefit insurance companies by increasing investment income on their fixed-income portfolios (float), although they can also lead to mark-to-market losses on existing bonds.

High inflation can negatively impact non-life insurers by increasing claims costs for property and casualty policies, necessitating higher loss reserves, and potentially eroding the real value of fixed dividend payouts for preferred shareholders like ACGLN.

Geopolitical tensions and conflicts, such as the Iran War escalation and potential Hormuz blockade, can lead to economic fragmentation, supply chain disruptions, and increased political violence or maritime risks. For insurers, this means heightened underwriting risks, potential increases in claims (e.g., marine insurance), and impact on overall economic stability that affects demand for insurance products.
