Parametric capacity describes the universe of underwriters, managing general agents and reinsurers willing and licensed to provide insurance limits on parametric terms. The capacity universe is concentrated in three locations — Lloyd’s of London, the wider London market, and Bermuda — supplemented by major European reinsurers (Munich Re, Swiss Re, SCOR) and a small number of specialist parametric MGAs. London has been the principal centre of parametric innovation since 2019, supported by the Lloyd’s Lab cohort programme and the Lloyd’s Product Innovation Facility.

Parametric capacity in the London market is provided by a combination of Lloyd’s syndicates, company-market carriers (Munich Re, Swiss Re Corporate Solutions, AXA, AIG, Hiscox, Beazley) and specialist parametric MGAs writing on syndicate paper or on Bermuda-based capacity. Principal MGAs and underwriters writing parametric in 2024-2026 include:
Parametric carriers operating in the United Kingdom must be authorised under FSMA 2000 Part IV (FCA/PRA dual-regulated insurers) or operating under a Lloyd’s coverholder or DA binder. MGAs not directly authorised as insurers must hold FCA authorisation as insurance intermediaries and act under properly executed binding authorities under ICOBS Chapter 7 expectations.
The Lloyd’s “syndicate-in-a-box” framework, introduced 2019, provides a streamlined route for parametric and other innovative propositions to enter Lloyd’s with smaller initial capital, typically GBP 10-50 million premium volume. Several parametric MGAs have used SIAB or graduated to full syndicate status via this route. The Lloyd’s Product Innovation Facility (LPIF, from 2022) provides supplemental capacity to managing agents for novel propositions including parametric. The Lloyd’s Lab cohort programme has hosted parametric propositions in cohorts 6 (2021) through 13 (2025).
The EIOPA Discussion Paper on parametric insurance (June 2023) confirms the parametric capacity universe’s growing scale and notes the concentration in London and Bermuda. PRA SS5/16 governs internal-model treatment for UK carriers.
A London broker placing a parametric risk identifies the likely lead market based on class — Descartes or Skyline for weather, FloodFlash for UK SME flood, AXA Climate for corporate weather, Munich Re for industrial property or pandemic, RenaissanceRe or Nephila for high-limit catastrophe — and quotes the slip. Co-insurance is common: a parametric flood programme might combine a 30% lead from FloodFlash with following lines from three Lloyd’s syndicates and a Bermuda collateralised reinsurer.
Capacity for retail consumer parametric is more constrained, with regulatory consumer-protection scrutiny limiting which firms will write the class. Capacity for very-long-dated covers (10-15 years for renewable PPAs) is provided principally by ILS-backed structures, with Bermuda and Cayman SPCs frequently used.
The capacity universe has expanded materially from 2020. New entrants include corporate captives (writing parametric for parent group exposures), insurtech-backed MGAs (with venture capital from Munich Re Ventures, Allianz X and similar), and dedicated parametric reinsurance vehicles (Swiss Re’s Public Sector Solutions for sovereign covers). The Lloyd’s Lab cohorts have systematically supported parametric: cohort 7 (2022) — Skyline Partners; cohort 8 (2022) — Arbol; cohort 11 (2024) — multiple parametric propositions.
A London broker structures a corporate parametric programme for a UK manufacturer exposed to typhoon in the Philippines, hurricane in the Gulf of Mexico and heatwave in Spain. The programme combines: a Descartes Underwriting lead line for typhoon and hurricane (USD 25 million); a FloodFlash sensor-based supplement for the UK head office (GBP 1 million); an AXA Climate heatwave layer for Spain (EUR 5 million); and Lloyd’s syndicate following lines on all three. The total annual premium is USD 1.8 million; total limit USD 35 million.
