Moody's RMS & VesperSpatial: The 2-Tier Enterprise Architecture

Moody's RMS is the undisputed global gold standard for 250-year stochastic event catalogs, treaty syndication, and AM Best BCAR defense. However, RMS was never engineered for sub-45ms point-of-bind intake or California CDI § 2644.9 statutory rate credits. Here is why leading commercial carriers deploy both in a modern 2-tier architecture.

Moody's RMS

Treaty Solvency Standard

The reinsurance capital currency. Essential for annual treaty syndication with Munich Re, Swiss Re, and Lloyd's syndicates, providing 10,000-year stochastic event catalogs.

Primary Objective:Annual 250-Year Treaty PML
Execution Cadence:Quarterly portfolio batch run
API Execution Latency:Minutes to hours (Batch queue)
Annual Licensing:$150,000 – $500,000+ / yr
Point-of-Bind Usability:Unsuited for real-time intake

VesperSpatial (Delphi-1.0)

Point-of-Bind Control Plane

Real-time transactional physics engine. Sits directly in broker intake portals to screen every quote for convective slope runs, 5-mile $25M caps, and CDI § 2644.9 credits.

Primary Objective:Instant Bind Decisions & Rating
Execution Cadence:Every quote submission (< 45ms)
API Execution Latency:< 45ms REST
Annual Licensing:$0 (Transactional $0.25/call)
Point-of-Bind Usability:Native sub-45ms integration
Enterprise Reference Architecture

How Modern Carriers Integrate RMS and VesperSpatial

Replacing RMS entirely is neither necessary nor advisable for surplus lines carriers syndicating treaty reinsurance. Instead, progressive Chief Underwriting Officers separate their capital solvency engine from their transactional intake engine:

Tier 1 · Operational Edge (Real-Time)Sub-45ms Latency

VesperSpatial Delphi-1.0

  • Embedded directly into Guidewire, Socotra, or custom broker portals.
  • Screens 100% of quote submissions at $0.25/quote with zero annual commitments.
  • Enforces 5-mile $25M PML radial corridor caps to prevent cluster conflagrations.
  • Computes all 10 California CDI § 2644.9 statutory mitigation credit tiers automatically.
Tier 2 · Capital Modeling (Periodic)Quarterly Batch

Moody's RMS (RiskLink)

  • Runs quarterly against the bound in-force policy bordereau.
  • Supplies the 250-year stochastic exceedance probability (EP) curve for treaty renewals.
  • Presented to rating agencies (AM Best, S&P) for corporate solvency defense.
  • Free from real-time API latency requirements and bind-ratio volume penalties.
Actuarial Synergies: By using VesperSpatial to enforce 5-mile $25M corridor accumulation limits at the point of bind, your quarterly RMS batch runs show dramatically lower tail PML concentration—directly lowering your annual reinsurance treaty reinstatement premiums!
