In September 2026, the Geneva Association published a report on global financial fragmentation showing that geopolitical tensions are beginning to reshape the capital flows, payment systems and cross-border risk-transfer mechanisms on which insurers and reinsurers depend. The central message is measured but important: fragmentation alone is unlikely to make international insurance markets unviable, yet it can make them less efficient, more regionalised and much more vulnerable when combined with a financial-market shock.

The report, written by Shamik Dhar and Darren Pain, moves the discussion beyond trade barriers and supply-chain disruption. It examines what happens when sanctions, regulatory divergence, capital-localisation rules, settlement frictions and political alignment constrain the movement of risk, capital and collateral. For insurance groups, this matters because the business model still relies on international diversification even when most primary policies are issued locally.

Fragmentation reaches both sides of the balance sheet

The Geneva Association identifies four transmission channels. The first is cross-border diversification. More restrictive rules can force groups to rely on local subsidiaries, branches or fronting arrangements, raising compliance costs and concentrating exposures. If risks cannot be pooled efficiently across jurisdictions, technical provisions and capital requirements may increase.

The second channel is reinsurance. Major hubs account for close to 40% of the global reinsurance market, according to the report. Sanctions, divergent prudential standards and ring-fencing can reduce access to that capacity or make recoveries slower and less certain. Primary insurers may therefore retain more risk locally, face greater claims volatility and pay more for protection.

The third channel concerns investments. Life insurers already display significant home bias, typically holding 40% to 50% of their bond portfolios domestically. A more fragmented system can reinforce that bias, narrow the investable universe and weaken geographic diversification. It may also increase sovereign concentration at exactly the time when public debt is rising.

The fourth channel is liquidity. Fragmented markets can obstruct access to foreign-currency funding, the mobilisation of collateral and derivatives margining. A rise in interest rates may simultaneously reduce asset values, increase surrender incentives and shorten liability duration. If capital and collateral cannot move across borders quickly, a manageable asset-liability mismatch can become a liquidity event and, through forced sales, a solvency problem.

Three scenarios and one critical warning

The report does not offer a forecast. Instead, it models three stylised scenarios across three regions described as Home, Partner and Rival. This is useful for boards because it separates gradual, targeted fragmentation from a disorderly event.

Under the Segmentation scenario, restrictions are concentrated on the Rival bloc, which has a relatively small cross-border insurance footprint. Reinsurance capacity in that bloc falls by around 35% and prices rise by about 8%. The effects remain localised: capacity becomes segmented, but there is no system-wide instability.

Under Reallocation, all blocs face frictions and global reinsurance capacity becomes binding. Rival reinsurance business falls by about 30%, while capacity in the Home bloc rises by more than 15%. Pricing diverges by region rather than increasing uniformly. Capital buffers decline modestly, by approximately 1.5% to 2.5%, and duration gaps widen. The lesson is that fragmentation does not simply destroy capacity; it changes where capacity sits, what it costs and whether it can be used where losses occur.

The Amplification scenario is the real stress case. Broad fragmentation coincides with an interest-rate and credit-spread shock. Surrenders, margin calls and collateral needs rise; shallow markets magnify forced-sale losses; and capital becomes less mobile when it is most needed. In the model, insurance capital in the Rival bloc initially falls by as much as 90%, implying emergency recapitalisation, group support or regulatory intervention. The figure is not a prediction, but it demonstrates the non-linear interaction between geopolitical constraints and conventional balance-sheet stress.

What multinational insurers benefits networks and captives should do

For international insurers and reinsurers, the strategic response is a shift from maximum global efficiency towards resilient regional optimisation, not wholesale retreat from global markets. The report recommends diversifying reinsurance counterparties across jurisdictions, reassessing enforceability, using regional hubs and stress-testing recoverables for delay or partial payment. Groups may also need to pre-position capital and liquidity in key markets, accepting some loss of fungibility in exchange for greater operational resilience.

The implications extend to multinational employee benefit programmes. Pooling and captive arrangements rely on local policies, fronting carriers, network agreements, cross-border data and financial settlements. A programme can appear well diversified on paper while remaining exposed to a small number of payment channels, fronting relationships or reinsurance counterparties. Sanctions or settlement restrictions may affect the timing and certainty of dividends, deficit funding, captive recoveries and claims reimbursements.

Networks, brokers and corporate risk managers should therefore map the complete chain from local premium collection to claims payment and final risk transfer. They should identify where capital, collateral, cash or data must cross borders; test whether alternative carriers and settlement routes exist; and distinguish contractual recoverability from practical recoverability during a crisis. Captive boards should also examine whether collateral is held in a jurisdiction and currency that remain accessible under stress.

Corporate sponsors should also revisit the assumptions behind programme concentration. Consolidating benefits with one global network can improve data quality, purchasing leverage and governance, but operational simplicity may conceal dependency on a limited set of local partners or intra-group settlement processes. Resilience analysis should therefore consider the network’s legal-entity structure, substitution rights, contingency arrangements and ability to continue reporting and paying claims if a country, bank or currency becomes temporarily inaccessible.

Employee benefit captives require a particularly joined-up view. Their liabilities may be short-tail, but medical inflation, disability claims and catastrophe-related mortality can create sudden funding needs. At the same time, collateral calls, trapped cash or delayed fronting settlements may reduce available liquidity. Stress tests should combine adverse claims with delays in premium remittance and recoveries, changes in collateral requirements and restrictions on upstreaming funds. The relevant question is not only whether the captive remains solvent on an accounting basis, but whether it can meet obligations in the right currency and jurisdiction at the required time.

The same logic applies to data. Multinational programmes increasingly depend on central dashboards and cross-border data aggregation. Localisation rules or geopolitical restrictions could interrupt data transfers even when insurance contracts remain valid. Boards and programme committees should identify the minimum data needed to price, reserve, settle and govern the programme, establish fallback reporting routes and confirm who can access records if a technology provider or jurisdiction becomes unavailable.

Governance is the final priority. The Geneva Association argues that geopolitical risk should be treated as a core business variable rather than an external backdrop. Boards should request scenarios that combine sanctions, market volatility, reinsurance impairment and liquidity pressure instead of reviewing each risk in isolation. They should also ask whether management information is granular enough to show concentrations by jurisdiction, counterparty, currency, settlement system and legal entity.

For policymakers, there is an unavoidable trade-off. Localisation may strengthen domestic control, but it can also reduce diversification, raise insurance costs and widen protection gaps. Supervisory cooperation, mutual recognition and interoperable payment and settlement systems will remain essential if the industry is to preserve the benefits of international risk sharing.

The report’s most useful conclusion is that preparation matters more than prediction. Financial fragmentation is likely to develop unevenly and may remain manageable for long periods. The danger arises when familiar financial stresses meet a system in which risk, capital and liquidity can no longer move freely. That makes fragmentation a board-level issue now, before a crisis reveals where the hidden barriers are.
