Reinsurance: Expert Video Analysis [Video Resource]

Updated October 1, 2026.

Direct answer: Reinsurance is insurance for insurers: carriers cede premium and loss to reinsurers via treaty programs (automatic) or facultative placements (risk-by-risk), using proportional or non-proportional structures. That backstop drives capacity, attachment points, and renewal pricing that flow through to commercial property buyers.

Why watch this first

The embed walks treaty versus facultative placement, proportional versus non-proportional structures, and why reinsurance sits behind many primary policies. Pair the video with our reinsurance fundamentals for policyholders if you need the cedent-to-policyholder chain in one pass.

What this video covers

The walkthrough covers treaty versus facultative placement, quota share and surplus sharing, and excess-of-loss towers with retentions and limits—a solid baseline before renewal or program design reading.

Reinsurance (working definition)

A contract where a reinsurer accepts defined exposure from a ceding insurer in exchange for premium. Treaties run on agreed terms for a class of business; facultative reinsurance is negotiated per risk. Retrocession is the same idea one layer up, when reinsurers cede to other reinsurers or capital markets vehicles.

Key takeaways

Treaty reinsurance is the default engine for portfolio transfer; facultative fills outliers, large limits, or unusual exposures.
Quota share and surplus treaties are proportional; excess of loss and aggregate covers are non-proportional and drive cat tower design.
Retrocession and multi-layer programs spread peak zones so no single balance sheet holds the entire tail.
Alternative capital, including catastrophe bonds and collateralized reinsurance, now sits beside traditional treaty panels on many programs.
January 1 and mid-year renewals reprice those layers; cedent retentions and attachment points move when loss years or capacity tighten.

Market context (through mid-2026)

Property cat reinsurance stays selective after heavy loss years, though January 2026 brought steadier pricing on many U.S. regional programs than the 2023–2024 repricing. Reinsurers still tighten aggregate terms and excess layers when severity trends run hot.

Artemis tracked about $17.98 billion of new cat bond and ILS issuance across 83 deals in H1 2026, with outstanding cat bond market size near $65.6 billion at end-June. Sponsors pair that collateralized capacity with traditional treaties; see parametric and index-based risk transfer for trigger mechanics versus indemnity covers.

Lloyd’s, Bermuda, and the January 1 cycle still anchor much U.S. property treaty business—see our global market and January renewal guide. For forms in the video, use the quota share versus excess of loss comparison.

Key terms glossary

Treaty reinsurance

Standing agreement covering a defined portfolio under preset terms without per-risk approval.

Facultative reinsurance

Single-risk or single-policy cession where the reinsurer accepts or declines each submission.

Quota share

Proportional treaty: reinsurer takes a fixed percentage of premium and losses on ceded business.

Excess of loss (XOL)

Non-proportional cover for losses above a retention up to a contract limit, often layered.

Retrocession

Reinsurance bought by a reinsurer to cap its own accumulation on a treaty or event.

Alternative capital / ILS

Cat bonds and collateralized vehicles that transfer specified risks to capital markets investors.

Frequently asked questions

Does reinsurance change what my property policy says?

Reinsurance contracts sit between your insurer and its reinsurers. Your declarations page and endorsements still govern your coverage, limits, and deductibles. Reinsurance matters to you when it affects whether your carrier can keep capacity in your region, how much limit they can offer, and how renewal pricing moves after large industry loss years.

What is the difference between treaty and facultative reinsurance?

Treaty reinsurance automatically covers an agreed book of business under set terms for a policy year. Facultative reinsurance is line-by-line: the reinsurer evaluates each risk before binding. Carriers use treaties for scale and facultative covers for exceptional exposures, jumbo limits, or risks that fall outside treaty scope.

How do quota share and excess of loss treaties differ?

Quota share is proportional: the reinsurer shares a set percentage of premium and losses from the ceded portfolio. Excess of loss is non-proportional: the cedent keeps losses up to a retention, and the reinsurer pays defined layers above that point up to stated limits. Many property programs combine proportional core treaties with XOL cat towers.

What are cat bonds and how do they relate to traditional reinsurance?

Catastrophe bonds are insurance-linked securities that pay investors until a defined trigger event occurs, at which point principal may be used to fund the sponsor’s losses. They complement traditional reinsurance by adding collateralized capacity, often alongside treaty and retrocession layers. First-half 2026 set issuance records, which keeps alternative capital visible on many renewal panels.

Why do January renewals get so much attention?

A large share of global property and casualty treaty programs renew on January 1, especially business written through Lloyd’s and Bermuda markets. Pricing, retentions, and attachment points set at that renewal flow into primary rate filings and capacity decisions over the following quarters. Mid-year renewals matter for accounts on non-standard dates but January sets the tone for many U.S. property cat programs.
