Bermuda's new Parametric Special Purpose Insurer class will reach the Insurance Act 1978 in the fourth quarter of 2026, and it will accept contracts "structured as reinsurance, derivatives, or swaps" so long as they show insurance risk transfer, transparent triggers and full collateral (Bermuda Monetary Authority, stakeholder letter, September 16, 2026). A PSPI holds $1 of paid-up capital and collateralises each contract to its aggregate limit.

What the regulator settled is which side of the line a swap sits on in Hamilton. Where it sits on the cedent's balance sheet depends on a different test, whether the index can pay when no loss occurred, and that test the letter does not touch.

Key Takeaways

  • Two quarters is the slip: the January consultation paper targeted an Insurance Act amendment "before the end of Q2-2026," and the September letter now says Q4 2026, with comprehensive guidance to follow at the same time (BMA, January 21 and September 16, 2026).
  • $1 of paid-up capital plus cash, cash equivalents or letters of credit "equal to or greater than their full exposure limit" on every contract is the PSPI capital structure; the Authority is reviewing "whether a limited expansion to include other assets may be appropriate" (BMA, January and September 2026).
  • A- or better was the cedant test for a standard SPI; a PSPI may also face "qualified regional and national corporates," governments and government-sponsored entities, a term the Authority has yet to define and promises guidance on (BMA, January 21, 2026).
  • 25 SPIs and 10 collateralised insurers were registered in Bermuda in 2025, the collateralised count a record, on a platform the consultation paper says carries more than 85 percent of global alternative capital capacity (Artemis, January 2026; BMA, January 2026).
  • $1.8 billion is CCRIF's parametric coverage for the current policy year, up 14.5 percent from the $1.57 billion reported in June and 25 percent from $1.44 billion a year earlier, the demand side arriving ahead of the framework (Artemis, September 15, 2026).

What the September Letter Changed From the January Paper

January's consultation proposed a dedicated SPI sub-class for "fully collateralised (re)insurance business" that "transfers risk via a parametric cover," defined as a contract "with predefined, measurable loss event(s) and specified payout amounts." Swap and derivative forms were to be allowed "on a case-by-case basis, which the Authority has approved," and the class was reserved for "traditional parametric business only," with innovative structures pushed to the sandbox regime (BMA consultation paper, January 21, 2026).

Respondents asked the obvious question: did "traditional" mean only contracts written as reinsurance? The Authority's answer moves the boundary. "The PSPI regime is intended to support structured, fully collateralised parametric risk transfer. The Authority will prioritise the substance of the risk transfer over the contractual form," and every contract "must demonstrate insurance risk transfer characteristics and be supported by appropriate governance arrangements, transparent triggers, and collateralisation arrangements" (BMA, September 16, 2026).

Three smaller decisions fill in the operating model. Insurers already writing parametric risk under other licence classes keep doing so without re-licensing. Existing SPIs may apply to reclassify, and the Authority "is also considering whether any introductory fee waivers for new PSPIs may apply to such reclassifications." Trigger integrity is delegated: applicants must show "the parametric trigger methodology is appropriately designed, data sources are independent and reliable, and settlement mechanics are transparent," with guidance on what makes a third-party validator "sophisticated" still to come (BMA, September 16, 2026).

Substance to the Regulator, Form to the Auditor

A regulator asking whether risk was transferred and an accountant asking whether a loss must occur are asking different questions, and a parametric swap can pass the first and fail the second. Under US GAAP a contract whose index threshold "can be triggered even if the insured did not sustain any economic loss" does not meet the definition of an insurance contract and is accounted for as a derivative under ASC 815, at fair value with changes through current earnings (JLK Rosenberger). Nothing in the BMA's test requires a loss; it requires a transparent trigger and enough collateral to pay it.

For a corporate or sovereign buyer that is a reporting choice, and sovereign pools such as CCRIF already make it. For an insurance cedent it decides whether the recovery counts. Reinsurance credit on a US statutory balance sheet attaches to a reinsurance contract, and the site recorded in June that carriers filing parametric layers against severe convective storm, wildfire and flood were choosing their own capital treatment because "the RBC formula offers no accommodation for a conditional recovery." A swap written by a Bermuda PSPI does not change that arithmetic in the cedent's domicile; it changes only what Hamilton calls the counterparty.

One fix is the step parametric cover was designed to avoid. A condition that the payout cannot exceed the cedent's ultimate net loss converts the contract into insurance for the auditor, and reintroduces loss adjustment between trigger and settlement. The BMA's substance test sits comfortably with either version; the cedent's accountant does not.

What the class does change is counterparty cost. Collateral to the full aggregate limit in cash or LOCs removes the credit risk that a rated reinsurer's parametric promise carries, and the $1 capital floor means the price of that collateral is the whole capital charge. Against 25 SPI registrations and a record 10 collateralised insurers in 2025 (Artemis, January 2026), the PSPI is a narrower vehicle with a wider door: fewer permitted structures, more permitted buyers.

Collateral Covers the Credit Risk and Leaves the Trigger

Full collateral answers the question of whether a PSPI can pay. It does not answer whether the trigger fires when the loss happens, and that is where the cedent's exposure remains. The site's June analysis put the basis risk ratio of a well-designed hurricane index program at 10 to 15 percent and county-level severe convective storm triggers at 30 to 45 percent depending on concentration. In July, Mexico's Mww 7.3 earthquake landed 0.1 short of the Class B trigger on its $595 million IBRD cat bond, and a tenth of a magnitude unit decided $17.5 million.

The letter places trigger design with "sophisticated" third-party validators the Authority has not yet defined, and lets transactions inside an approved business plan proceed without further review. That is a supervisory model that trusts the modelling firm and the data vendor, which is the same kind of pair that priced the Mexico box. Demand is not waiting for the guidance: CCRIF's $1.8 billion of coverage is 25 percent above last year's and arrived midway through hurricane season (Artemis, September 15, 2026).

The framework will therefore open two quarters late with its capital rule fixed, its contract-form rule settled, and its two hardest terms, "sophisticated participant" and "sophisticated validator," still to be written. A swap can be a reinsurer in Bermuda by December. Whether its payout is a reinsurance recovery in Des Moines or Hartford is a question the cedent's actuary answers alone.
