Chubb Limited — Key Risks

Catastrophe Losses Are Unpredictable and Could Be Severe

As a global insurer, Chubb takes on enormous risk from hurricanes, earthquakes, terrorism, and increasingly, cyber catastrophes. Unlike physical disasters, a large-scale cyber event has no geographic boundaries and is engineered by human actors who constantly adapt to defeat existing defenses. One or more major catastrophes in a given year can cause dramatic swings in earnings and financial condition.

Reserve Estimates May Prove Wrong, Costing Real Money

Chubb sets aside money today to pay future claims — these are called loss reserves. Getting this estimate wrong is a genuine risk. Particularly tricky are asbestos and environmental (A&E) liabilities, which at year-end 2025 represented about 1.4% of gross reserves. These claims are shaped by shifting legal standards, court decisions, and "social inflation" (the tendency of juries to award larger verdicts over time), all of which can force unexpected reserve increases that directly reduce net income.

$20.6 Billion in Reinsurance Recoverables Depends on Counterparties Staying Solvent

Chubb buys reinsurance (insurance for itself) to limit its exposure to large losses, but this creates counterparty risk — if those reinsurers can't or won't pay, Chubb still owes its original policyholders. At December 31, 2025, it had $20.6 billion in reinsurance recoverables outstanding. A related internal concern: its run-off subsidiary Century Indemnity has $1.9 billion in reinsurance obligations to Chubb's active units, and if Century were to become insolvent, those recoverables could be at risk.

Variable Annuity Reinsurance Adds Market-Driven Earnings Volatility

Chubb assumed guaranteed minimum death and income benefit risks on variable annuity contracts (business it stopped writing in 2007, but still carries). These liabilities move with stock markets and interest rates every quarter, creating direct swings in reported net income regardless of how the core insurance business is performing. Chubb itself compares this to catastrophe reinsurance in terms of risk profile.

Operating Across 54 Countries Brings Complex, Shifting Regulatory Exposure

Chubb operates in 54 countries and faces a web of insurance regulations, capital requirements, privacy laws, and climate disclosure mandates. New frameworks like the OECD global minimum tax (15% effective 2024 in many jurisdictions) and Bermuda's new 15% corporate income tax (effective January 1, 2025) are concrete, recent examples of regulatory changes that directly increase Chubb's tax burden. Evolving AI regulations across the U.S., EU, and Asia could also raise compliance costs and limit how Chubb uses data-driven tools.

Swiss Incorporation Creates Specific Constraints on Capital Returns

Because Chubb is incorporated in Switzerland, share buybacks depend on shareholder approval and Swiss tax rulings that must be periodically renewed. If shareholders don't approve the required authorizations — or if Swiss tax authorities decline to renew favorable rulings — Chubb's ability to return capital through repurchases could be curtailed. Dividends structured to avoid Switzerland's 35% withholding tax are currently expected to remain available only until roughly 2032–2036.
