OSFI Opens MCT Capital Credit to Indemnity Cat Bonds With Collateral Held in Canada

OSFI amended Section 4.3 of its Minimum Capital Test guideline on July 20, 2026, to recognize natural catastrophe bonds as reinsurance for insurance-risk capital credit, effective immediately (OSFI, July 2026). Qualifying bonds need an indemnity trigger, collateral in high-quality assets held in Canada, full funding under a reinsurance security agreement, and prior approval; OSFI classifies them as unregistered reinsurance with no margin requirement.

The change arrives as a regulatory notice rather than a full guideline reissue, and OSFI will fold the provisions into the next version of the MCT, rescinding the interim notice at that point (Insurance Business, July 2026). Scope is deliberately narrow. Every federally regulated property and casualty insurer except mortgage insurers can apply, and the eligible perils are natural catastrophes only: earthquake, flood and wildfire qualify, while terrorism, industrial accidents and cyber stay out. The boundary has bite: the wider market priced its first US terrorism catastrophe bond only weeks earlier, and OSFI is drawing the capital-credit line at modelled natural perils. Approval is transaction-specific. The application file runs from the bond contracts and offering documents to stress-testing output on the collateral. OSFI also wants the special purpose vehicle's inter-company agreements, plus confirmation that no cross-default triggers sit anywhere in the structure (Insurance Business, July 2026).

What Changes Inside Section 4.3

Section 4.3 is where the MCT decides whether ceded risk actually leaves the capital base. Registered reinsurers, meaning federally regulated carriers plus a short list of provincial and public entities, pass credit through subject only to counterparty credit factors. Every other counterparty is unregistered, and the guideline deducts recoverables from unregistered reinsurers out of capital available unless the cedent holds acceptable security: non-owned deposits under a reinsurance security agreement, funds held, or letters of credit capped at 30% of reinsurance contract assets (OSFI MCT Guideline, 2026).

Dollar-for-dollar coverage alone does not finish the job. The guideline layers a margin on top, equal to 20% of the unexpired-coverage premiums and incurred-claims recoverables due from the unregistered counterparty, and that margin shrinks to zero only where premiums payable and acceptable collateral exceed the exposure itself (OSFI MCT Guideline, 2026). A cedent taking full credit for a collateralized cover from an unregistered Bermuda reinsurer therefore needs roughly 120 cents of security per dollar of ceded exposure before its MCT ratio reflects the whole cession.

The no-margin classification is the load-bearing clause, because a catastrophe bond cannot post 120 cents. Investors fund the collateral trust at exactly the principal they put at risk: the limit is the trust and the trust is the limit. The 20% margin exists to buffer the gap between what a troubled reinsurer owes and what it happens to have pledged. A fully funded trust carries no such gap: recoveries can never exceed collateral that is already sitting in cash-equivalent form before the risk period starts. Waiving the margin is less a concession than an acknowledgment that a limit-equals-collateral structure has nothing left to secure.

The Indemnity Condition Against the Market's Trigger Mix

The condition that reads most restrictive turns out to track where sponsor issuance already sits. Indemnity triggers accounted for 81% of second-quarter 2026 cat bond issuance, $9.2 billion across 55 of 80 tranches, while industry-loss index structures took 15% and parametric deals $360 million, just over 3% (Artemis, July 2026). The quarter itself was the largest in the market's history at more than $11.3 billion of issuance, and half-year volume reached almost $18 billion against the prior record of $17.6 billion (Artemis, July 2026). The outstanding market ended June at $65.6 billion. OSFI's condition ratifies the dominant structure and refuses credit to the remaining fifth of the market.

From the regulator's chair the choice is a basis-risk decision. An index or parametric recovery settles on modelled or industry-wide quantities, so the cedent keeps the residual between what the instrument pays and what its gross loss turns out to be. A formula-driven capital test has no cell for that residual. Grant an index bond full credit and the MCT would overstate protection in exactly the tail scenarios the test exists to capitalize. Indemnity settlement ties the recovery to the insurer's own booked loss, which makes credit equal transfer by construction. The cost lands on the investor side of the trade. Buyers of an indemnity deal absorb the sponsor's underwriting quality, claims practices and loss development, and they price the structural controls that manage it: TD's 2026 aggregate carries a C$25 million event deductible and a C$175 million per-event cap (Artemis Deal Directory, January 2026).

The exclusion still has an edge. Parametric issuance is where sovereign and development-bank deals live, index triggers are common in retrocession, and a Canadian carrier wanting capital credit for index-based protection stays outside the tent. For primary sponsors the practical burden is disclosure and time: an indemnity bond needs offering-document detail on the subject business and a loss-development mechanism running through an extension period, paperwork an industry-loss settlement avoids. OSFI has decided the capital formula will pay for none of that shortcut.

Collateral in Canada, Wrapper in Bermuda

MMIFS Re Ltd., the vehicle behind both Canadian deals to date, is a Bermuda special purpose insurer. Both transactions parked proceeds in European Bank for Reconstruction and Development notes paying roughly Canada's overnight benchmark CORRA less a small margin (Artemis Deal Directory, January 2026). Currency, the first structural problem for a pure Canadian cat bond, was solved at the debut: both series are Canadian-dollar denominated, the market's first. What the notice adds is situs. Collateral must sit in Canada, fully paid, under a reinsurance security agreement, which is the same priority-security-interest plumbing Canadian cedents already operate when they take credit for collateralized covers from unregistered reinsurers.

That requirement redirects rather than reinvents the structure. Nothing in the notice forces the issuing vehicle onshore, so the Bermuda incorporation, the 144A distribution and the existing ILS investor base all survive. The trust assets move to Canadian custody, where the cedent's security interest can be perfected under Canadian law. The open structuring questions are narrow: whether supranational paper like the EBRD notes can be held through a Canadian account that satisfies OSFI, or whether qualifying collateral drifts toward Government of Canada treasury assets, and how many basis points that answer costs at issuance. Against a waived 20% margin and a zero counterparty charge, the budget for those basis points is generous.

The notice also keeps the collateral itself inside the capital net. Qualifying assets stay subject to the MCT's capital requirements for unregistered reinsurance collateral, so the trust portfolio attracts asset-risk factors by type and credit quality like any other security the cedent looks through to (OSFI, July 2026). That is the quiet argument for boring collateral: a trust of Government of Canada bills minimizes the look-through charge along with the legal work, while supranational notes buy a few basis points of yield at the price of a longer conversation in the approval file.

Two MMIFS Re Series as the Pricing Baseline

TD Insurance built the only Canadian baseline anyone has. The debut, MMIFS Re Ltd. Series 2025-1, placed C$150 million of per-occurrence protection for Canadian earthquake and severe convective storm in January 2025, attaching at C$2.35 billion of loss and pricing at a 2.9% spread against a 0.42% initial expected loss (Artemis Deal Directory, January 2025). The return trip in January 2026 bought C$115 million of annual aggregate cover across five perils, attaching at C$350 million with exhaustion at C$500 million. It settled at a 6.75% spread against a 1.96% expected loss, after guidance opened at 5% to 5.5% and the target size came down from C$125 million (Artemis Deal Directory, January 2026).

Series	Size	Perils	Structure	Spread	Initial expected loss
2025-1 (January 2025)	C$150m	Earthquake, severe convective storm	Per occurrence, attaches at C$2.35bn, term to end 2027	2.9%	0.42%
2026-1 (January 2026)	C$115m	Named storm, earthquake, SCS, winter storm, wildfire	Annual aggregate 2026-2028, C$350m attachment, C$500m exhaustion, C$25m event deductible	6.75%	1.96%

The two prints bracket the market's read on Canadian risk. The remote earthquake layer cleared at roughly 6.9 times expected loss, a full multiple but recognizably in line with low-probability diversifying perils. The working-layer aggregate cleared at about 3.4 times, and only after investors pushed the spread roughly 29% above the original midpoint, in a year when spread compression has been the running story everywhere else. Aggregate Canadian severe convective storm and wildfire exposure, the risk behind 2024's loss record, is what got repriced hardest. TD paid both spreads with no MCT relief attached; the notice reprices the next series before a dollar of spread moves.

C$8.5 Billion in 2024 as the Demand Driver

CatIQ put 2024 insured catastrophe losses at C$8.5 billion, the costliest year on record for Canadian insurers and well past the C$6.2 billion set in 2016 (CatIQ, January 2025). Twelve events cleared the C$30 million catastrophe threshold, and claims volume reached 273,000 against the prior record of 197,000. CatIQ president and CEO Laura Twidle noted that four separate billion-dollar events landed inside a 27-day window and combined for more than C$7.5 billion. The per-event stack ran C$3 billion for the August Calgary hailstorm, C$2.7 billion for the remnants of Hurricane Debby, C$1.1 billion for the Jasper wildfire and C$990 million for southern Ontario's July flash flooding (Canadian Underwriter, January 2025).

Loss experience built the sponsor demand two years before regulation rewarded it. A market that averaged C$701 million a year in catastrophe losses from 2001 through 2010 now absorbs that much in a single mid-sized event. The 2023 season set the national frequency record at 24 catastrophes; 2024 set the severity one (CatIQ, January 2025). TD Insurance framed its second bond in exactly those terms: "Through this second catastrophe bond, we're able to help manage rising costs of these events to provide the most competitive pricing possible for our clients" (TD Insurance president and CEO James Russell, via Artemis, January 2026). Reinsurance budgets calibrated to C$700 million years do not stretch to C$8.5 billion ones without new capacity, and the deepest pool available is the $65.6 billion catastrophe bond market OSFI has now plugged into the MCT.

The Capital Term in the Sponsor's Cost Comparison

Credit already existed in one corner of the MCT. The guideline computes earthquake reserves as the earthquake premium reserve plus the earthquake reserve component, all multiplied by 1.25, where the component equals earthquake risk exposure less financial resources, floored at zero. The eligible resources already included reinsurance coverage and capital market financing alongside the premium reserve and at most 10% of capital and surplus (OSFI MCT Guideline, 2026). An earthquake bond therefore had a path to relief before this month. What it lacked was standing as reinsurance for the rest of the insurance-risk calculation and for every peril outside earthquake, including the severe convective storm, flood and wildfire exposures that generated most of 2024's C$8.5 billion.

The earthquake line shows the leverage. A dollar of qualifying protection that closes the earthquake reserve component gap removes C$1.25 of required capital; at the industry-wide supervisory target of 150%, that is roughly C$1.88 of actual capital held (OSFI MCT Guideline, 2026). Internal targets, which Guideline A-4 requires to sit above the supervisory level, raise the multiplier further. In round numbers, C$100 million of limit that closes an equivalent component gap carries about C$188 million of held-capital relief. At a 10% hurdle rate the capital term alone is worth nearly C$19 million a year, against annual spread bills the two TD prints bracket at 2.9% and 6.75% of limit. Outside earthquake, a qualifying bond now enters the reinsurance-contracts-held side of the insurance risk margins, shrinking the net bases that the 1.10 loading and the class risk factors multiply. Post-event recoverables stand as collateralized assets rather than deductions from capital available.

For the sponsor decision, the comparison reduces to observable prices on equal footing. A collateralized cover from an unregistered reinsurer carries its 120% security burden priced into the quote; a registered cession carries counterparty credit factors; the qualifying bond carries a multi-year fixed spread, no reinstatement premium, and, as of July 2026, the same capital credit as either. Capital and pricing actuaries at cat-exposed Canadian carriers should re-run their 2027 program optimizations with the bond leg included. New issuance should be designed to the four conditions from the term sheet forward: indemnity settlement, Canadian-situs collateral in high-quality assets, full funding under a reinsurance security agreement, and the approval file assembled before launch. Watch two things through the fall: how quickly OSFI turns approval files around, and whether the onshore-collateral requirement shows up as basis points in the next print. TD priced two series without the credit. The first sponsor to price one with it will show the market what the notice is worth.
