Forecast For Insurance Treaty Renewals – 2026

Executive summary (short)

The reinsurance renewal environment going into 2026 looks set to remain broadly favourable to buyers — although not uniformly so across all lines or layers. Reinsurer capacity is high, alternative capital remains significant, and many brokers and reinsurers are forecasting continued rate softening or stabilisation for well-performing programmes, particularly on lower and mid layers of property catastrophe and many specialty lines. At the same time, reinsurers will remain selective and disciplined: accounts with recent deterioration in loss experience, concentration issues, or weak data and modelling will see less relief and, in some cases, rate hardening or stricter terms. Casualty (long-tail) markets are generally expected to be stable-to-hard depending on jurisdiction and segment, while cyber, energy and some specialty sectors will show greater segmentation — some programmes may see material rate reductions, others will face rate increases or capacity constraints. The overall message to cedants: present clean, high-quality data, demonstrate exposure management and mitigation, and be prepared to negotiate structure and attachment points as the market becomes more competitive.  

1. Macro drivers shaping 2026 renewals

1. Record (or near-record) reinsurance capital. Dedicated reinsurance capital and alternative capital (cat bonds, sidecars, collateralised structures) are at historically high levels. This abundance of capacity is a principal reason for softening rates in many segments.  

2. Loss experience and catastrophes remain relevant. Despite larger pools of capital, recent severe natural catastrophe years and large loss events still drive selective tightening on exposed accounts and higher layers. Where insured catastrophe losses have been high, reinsurers will be cautious and pricing will reflect regional loss trends and climate risk.  

3. Macroeconomics and investment returns. Higher risk-free rates compared with the low-rate environment of earlier years are improving reinsurers’ investment returns — enabling capacity deployment — but macro uncertainty (slower growth in some regions) keeps reinsurers attentive to underwriting quality.  

4. Competition & strategic growth. Many reinsurers are seeking growth (organic and by client retention), which produces competitive pricing and flexibility on terms for attractive accounts. At the same time, the continuing presence of alternative capital means price pressure at certain layers is likely to persist.  

2. High-level expectation for rate movements (summary)

• Property (catastrophe-exposed layers): Expect softening on lower and mid layers for well-performing, diversified portfolios — typical reported decreases are in the mid-single digits to low-teens percentage points on renewal for accounts with no recent losses; highly competitive situations (tenders) have seen reductions materially larger (in some instances 20–50% in parts of 2025). Top (extreme) layers and accounts with poor loss histories or significant concentration may see modest increases or only marginal relief.  

• Property (attritional and primary property): Pricing pressure on primary/retail property and attritional layers is weaker — primary insurers have retained more risk and have greater incentive to seek reinsurance at competitive terms; reinsurers will compete, so cedants with clean portfolios should see opportunities for rate reductions or expanded terms.  

• Casualty (short-tail like motor vs long-tail like liability): Mixed / generally stable. Short-tail casualty lines (motor) may see modest relief in some jurisdictions; long-tail casualty (general liability, professional indemnity, directors & officers) remains more nuanced — in some territories insurers continue to seek rate improvement, and reinsurers remain selective because of reserving uncertainty and latent claims inflation. Overall expectation is stability with pockets of hardening where loss trends are adverse.  

• Cyber: Highly segmented. For clients with robust cyber risk management, strong incident response and low loss frequency, reinsurers are competing and pricing can soften. For portfolios with material loss activity, systemic exposures, unclear aggregation, or weak controls, reinsurers remain cautious and prices may increase. Product design and exclusions remain important negotiation levers.  

• Energy (upstream/downstream) and specialty: Very rate-sensitive and account-specific. Competitive tenders have produced steep reductions in some energy classes in 2025 (reports of reductions up to 50% on competitive placements), though accounts with recent large losses or exposure to volatile jurisdictions will not see the same relief. Overall expect continued segmentation.  

• Marine, Aviation, Agriculture, Political Risk: Each will follow its own supply/demand dynamics. Subsegments with strong underwriting discipline and improved loss ratios may attract rate reductions; others with volatility will face selective capacity restrictions.  

(These are directional expectations — the precise movement for any treaty will depend on the cedant’s loss history, portfolio mix, model outputs, and negotiating approach.)

3. Segregation by line — detailed expectations and drivers

3.1 Property catastrophe (material lines: US wind/hail, European convective, flood, earthquake)

• Lower and mid layers: Continued downward pressure on pure rate-on-line for accounts with good loss experience, diversified portfolios and proven catastrophe modelling. The abundance of capacity (traditional and alternate) will keep reinsurers competing on price and terms. Brokers report that clean placements have achieved significant rate reductions during 2025 renewals; that trend is expected to extend into 2026 where loss experience remains benign.  

• Top layers / aggregate layers: Less elasticity. Demand for capital protection at the very top can keep pricing firmer, especially where investors in alternative capital require commensurate returns. If reinsurers reprice top-end tail risk due to modelling updates (eg climate-driven return-period changes), increases are possible.  

• Regional differentiation: Regions with recent very large losses (e.g. countries with catastrophic flood/wildfire years) will see more differentiation — cedants in those regions must expect closer scrutiny and possibly less favourable movement.  

3.2 Casualty (short and long tail)

• Long-tail liability (D&O, GL, PI): Pricing is likely to be stable to firm for less well-performing accounts or those exposed to social inflation/reserving risk. Some places show modest improvement where primary pricing has tightened and cedants can demonstrate improved underlying loss ratios. Renewals will hinge on reserve adequacy and portfolio segmentation.  

• Motor and other short-tail: Pressure to compete — buyers may extract improvements, particularly in markets where traffic exposure and claims frequency have normalised or improved.  

3.3 Cyber

• Heterogeneous outcomes. Reinsurers continue to deploy capital into cyber but remain selective: well-underwritten programmes with effective cyber hygiene, modern underwriting data and clear aggregation treatment can benefit from competition; portfolios with repeated incidents, poor control environments or unclear limits will face constrained capacity and higher rated renewals. Policy wording (systemic aggregation, war/terror exclusions, state-sponsored activity carve-outs) will remain material negotiation points.  

3.4 Energy and Marine

• Energy (upstream/downstream): Competitive placements have driven sharp cuts in some segments; however, volatility remains and reinsurers will select risks carefully. Expect continued buyer leverage for clean, diversified portfolios and more conservative terms for higher-hazard operations or politically volatile regions.  

• Marine & aviation: Niche technical underwriting remains valuable. Rates will follow loss trends and fleet/cargo exposures. Aviation is sensitive to traffic recovery and large losses (hull total losses); marine will follow global trade volumes and claims pattern.  

3.5 Specialty (political risk, trade credit, agriculture)

• Specialist capacity and parametric structures will continue to develop. Pricing outcomes will be highly account specific; buyers who sponsor credible risk mitigation and provide rich underwriting data will be in a stronger negotiating position.

4. Why some accounts see rate reductions while others don’t

Key differentiators:

• Loss history and frequency of recent claims. Clean records attract competition; accounts with recent large losses or trend deterioration will not.  

• Portfolio diversification and accumulation control. Reinsurers price heavily for aggregation risk; cedants who demonstrate diversified exposure or clear accumulation management get better terms.  

• Quality of data and modelling. High-quality exposure data and defensible catastrophe model outputs shorten negotiation friction and reduce perceived model risk.  

• Use of capital markets / alternative capital. Where a cedant can layer risk into cat bonds or collateralised capacity, pricing pressure on traditional reinsurance tends to increase.  

• Terms and conditions beyond price. Attachment points, reinstatement terms, exclusions and aggregate structures can shift economics even when headline rates fall. Savvy cedants will trade structure for rate.  

5. What insurers (cedants) must present — the data and documentation checklist (and why)

To secure the best possible terms at 2026 renewals, insurers should provide a clear, auditable, and compelling submission package. Below is a practical checklist, grouped by purpose, together with explanations of why each item matters to reinsurers and brokers.

A — Exposure and portfolio detail (must-have)

1. Exposure inventory / exposure bases

• Buildings/locations with geo-coordinates, sums insured, construction type, occupancy, deductible information, and exposure values by line and jurisdiction.

• Why: Enables accurate catastrophe modelling, aggregation analysis and layer-by-layer pricing. Geo-coded data reduces model uncertainty.  

2. Exposure maps and accumulation summaries

• Per peril and per-event accumulation profiles; largest single exposure and concentration metrics.

• Why: Reinsurers need to assess worst-case accumulation and to price top-layers appropriately.

3. Premium and limit schedules

• Current premiums, limits, retentions, structure of the treaty and detailed attachment points.

• Why: Allows reinsurers to calculate expected loss ratios and rate-on-line consistent with cedant structure.

B — Loss history and reserving information

4. Complete claims history (ideally 5–10 years), with paid and outstanding, claim cause, date of loss, and ultimate development patterns.

• Why: Underpins underwriting judgement on loss frequency/severity and reserving adequacy — central for long-tail casualty appetite.  

5. Loss ratio analyses and trends

• By line and by vintage; commentary on material movement and remedial actions taken.

• Why: Demonstrates transparency and insights into drivers of past performance.

C — Modelling outputs and assumptions

6. Catastrophe model reports (vendor, version, modelled loss curves, AAL, PMLs for specified return periods) and model sensitivity tests.

• Why: Reinsurers must reconcile cedant model outputs with their own views; poor or undocumented models increase model risk and pricing margins.  

7. Exposure modelling assumptions and methodology notes

• Probabilistic vs deterministic approaches, vulnerability functions used, demand surge assumptions, inflation scenarios.

• Why: Helps reinsurers map differences between their pricing models and the cedant’s submission.

D — Risk management and mitigation evidence

8. Loss control and mitigation measures

• Building codes, sprinklers, early-warning systems, catastrophe risk engineering outcomes, prevention programmes, cyber hygiene protocols.

• Why: Demonstrates risk reduction, which can materially influence pricing and capacity offered.  

9. Reinsurance and capital structure transparency

• Current reinsurance programme attachments, limits, reinstatement provisions, any parametric or alternative structures (cat bonds, sidecars) in place.

• Why: Shows existing protection, potential overlap and overall capital adequacy.

E — Strategy, governance and change management

10. Underwriting strategy and portfolio targets

• Statements on growth plans, risk appetite, segments being expanded or exited.

• Why: Reinsurers prefer stable, predictable partners — sudden growth without adequate underwriting controls is penalised.

11. Reserving methodology and actuarial reports

• Independent actuarial opinions, reserving adequacy commentary, and sensitivity to reserve uncertainty (especially for casualty).

• Why: Reinsurers price for reserve risk; credible reserving reduces perceived tail uncertainty.

F — For cyber and complex lines — specific additional items

12. IT architecture, third-party vendor usage, incident response plans, ransomware loss severity distributions.

• Why: Cyber is highly dependent on control environment and likely systemic aggregation — reinsurers require granular, operational detail.

G — Presentation, format and data quality

13. Machine-readable data (csv/SQL) and a summary pack (executive one-pager + key tables).

• Why: Speeds broker and reinsurer analysis; reduces friction and the “model risk” premium charged for manual or ambiguous submissions.

14. Consistency and auditability — ensure numbers reconcile across schedules, treaties and model outputs.

• Why: Inconsistent submissions create doubt, which translates into higher pricing or less capacity.

6. Practical reasons why reinsurers demand this data

• Reduce model & information asymmetry. Better data lowers reinsurers’ uncertainty about true risk exposures and leads to tighter pricing.  

• Accurate aggregation and capital allocation. Reinsurers must understand potential peak losses and how they fit within their portfolio; cedants that help quantify aggregation reduce the need for conservative “buffer” pricing.  

• Demonstrate active risk management. Evidence of mitigation reduces expected loss and often allows access to more capacity on better terms.  

• Faster negotiation and competitive quoting. Clear submissions attract more quotes and increase buyer leverage; opaque submissions invite conservative pricing or fewer offers.  

7. Negotiation and structuring levers for cedants in 2026

1. Revisit attachment points and layering. If reinsurers are competing on lower layers, cedants can push for higher limits at existing attachment points, or purchase cheaper lower-layer capacity to preserve capital. Conversely, consider retaining more on low-severity layers if pricing is poor relative to expected losses.  

2. Offer alternative structures. Collateralised reinsurance, multi-year deals, or quota share/stop-loss solutions can be attractive to reinsurers and may secure improved economics.

3. Use of market testing and tenders. Competitive tenders can reveal material rate improvement — but be careful: aggressive tendering can reduce incumbent reinsurer appetite if relationships are not managed.

4. Data room & predisposition. Provide a well-organised data room and model reconciliation early to reduce reinsurer due diligence time and remove excuse for pricing conservatism.

5. Consider blended approaches for cyber and specialty lines. Where capacity is constrained, layer protection across traditional reinsurers, market forms and parametric triggers to achieve cost-effective cover.

8. Regional differences & regulatory considerations

• North America & Europe: Large pools of capital and active alternative markets make these renewals especially competitive for clean accounts; however, regional loss trends (hurricanes, convective storms, floods) will influence local outcomes.  

• Emerging markets: Capacity can be more limited and reinsurers may price for political and accumulation risk — cedants in emerging markets should expect less uniformity in outcomes.  

• Regulatory & capital requirements: Solvency regimes (eg Solvency II equivalents) and local capital rules may influence cedants’ appetite to retain risk versus transfer. Insurers should present how reinsurance supports regulatory capital and solvency positions during negotiations — it strengthens their case with reinsurers.  

9. Practical checklist for the 2026 renewal calendar (what to do and when)

• Q3–Q4 (prior year): Begin internal exposure data cleaning; commission updated cat models and engineering surveys where needed; identify high-priority treaties for market testing.

• ~60–90 days before renewal: Finalise submission pack, engage broker(s) with clear objectives, run loss-control remediation if possible.

• 30–60 days before renewal: Circulate data room and model reconciliations; host reinsurer calls or site visits for major accounts.

• Immediate pre-renewal: Run competitive tender where appropriate; be ready to trade structure for pricing (eg higher attachment in exchange for lower rate).

(Precise timing depends on market custom in each line and geography — some treaties have bespoke timelines.)

10. Risks and uncertainties to monitor

• Unexpected catastrophe years — a new year of elevated insured losses would quickly narrow buyer leverage.  

• Model updates and scientific developments — new views on perils (eg auto-correlation in convective storms, flood modelling updates) could change pricing dynamics mid-cycle.  

• Geopolitical or systemic cyber events — large systemic cyber losses or renewed geopolitical instability could stress capacity in affected lines.  

11. Recommendations — what insurers should do now (practical, actionable)

1. Invest in data cleanliness and model reconciliation. The single best way to unlock competitive pricing is to remove uncertainty. Deliver geo-coded exposures, reconciled PMLs, and an auditable claims history.  

2. Be transparent on portfolio strategy and material changes. Reinsurers prize predictability: explain growth plans, underwriting changes, and remediation actions after losses.

3. Focus on accumulation control and mitigation. Demonstrate how you manage peak exposures — this can be as valuable as a direct price reduction.

4. Engage brokers early and explore alternative capital. Use specialist advisors to shape the market process and to consider parametric or capital-market options where they improve economics.  

5. Segment renewals where useful. Consider separating highly attractive portfolios from others so that high-quality books are not cross-priced with weaker portfolios.

6. Prepare to trade structure for price. Be ready to adjust attachment points, reinstatement terms or co-participation to obtain better rates.

12. Therefore

Going into 2026, the reinsurance market is broadly more benign for buyers than the hard cycles of recent memory. Plenty of capital (traditional and alternative) plus a competitive reinsurer agenda means many insurers will be able to secure improved pricing or expanded terms — particularly for well-underwritten, diversified and well-documented portfolios. Nonetheless, the market is increasingly discriminating: cedants who provide high-quality data, demonstrate active risk management and can explain their reserving and underwriting philosophy will be rewarded; those who cannot should expect less favourable outcomes. Lines such as property catastrophe lower and mid layers look set to see the most marked softening, while casualty, cyber and several specialty lines will remain segmented and require more careful negotiation. Preparation, transparency and structuring flexibility will determine who benefits most from the 2026 renewal cycle.
