Growing fragmentation of the global financial system could amplify shocks across insurance markets when combined with broader financial-market stress, according to a new report by The Geneva Association.
The report examines how geopolitical tensions and increasing barriers to cross-border finance are changing the operating environment for insurers and reinsurers. The effects could be felt across international risk transfer, investment and capital management.
Financial fragmentation by itself is expected to have manageable implications for insurers. However, the risks become more significant when fragmentation occurs alongside market stress.
One major concern is cross-border reinsurance. Restrictions or barriers affecting international capital flows can make reinsurance capacity more difficult to access. This could increase coverage costs and leave insurers retaining a larger proportion of risks within domestic markets.
Reduced access to international diversification could also affect insurers’ investment portfolios. International insurers may have fewer opportunities to diversify geographically, while restrictions on capital movement could result in less efficient allocation of assets and liabilities.
Liquidity is another important concern. During periods of market stress, restrictions on cross-border financial flows could place additional pressure on insurers’ liquidity and capital buffers. This could increase balance-sheet vulnerability precisely when financial resilience is most important.
The implications extend to reinsurance and capital management strategies. Insurers may need to reconsider how much risk they transfer internationally, where they maintain capital and how they structure their investment portfolios.
The Geneva Association recommends that insurers respond by reconfiguring risk-transfer strategies, adapting capital structures and strengthening liquidity management. Policymakers also have an important role in maintaining cross-border supervisory cooperation and protecting payment and settlement infrastructure.
The issue is particularly relevant because insurance is fundamentally built around international risk sharing. Reinsurance allows risks to be distributed across geographic markets and capital providers, helping individual insurers absorb large or concentrated losses.
Greater financial fragmentation can weaken this mechanism. If capital becomes increasingly restricted by geography or regulatory barriers, insurers may have to retain more risk locally, potentially increasing concentration.
The report therefore highlights the need to examine the asset and liability sides of insurers’ balance sheets together. Fragmentation can simultaneously affect investment portfolios, reinsurance availability, liquidity and capital requirements.
For insurers and reinsurers, the emerging risk environment requires scenario analysis that considers not only underwriting losses but also geopolitical developments, capital restrictions and market stress occurring at the same time.
The broader concern is that financial fragmentation could turn an individual market shock into a wider insurance-sector problem when several transmission channels operate simultaneously.
As geopolitical considerations increasingly influence financial markets, insurers will need to assess how changes in cross-border capital flows could affect risk transfer, diversification, liquidity and balance-sheet resilience.
