30-Year Amortizations Drove Sagen Volume 18% Higher While Claims Ate the Profit
The line between more business and better business is not always visible in an earnings report until the claims start rolling in. Sagen MI Canada wrote $473 million in new premiums last quarter, up 18% from the same period in 2025, powered almost entirely by Ottawa's expansion of 30-year amortization eligibility to first-time buyers and anyone purchasing a newly built home. The insurer is now booking revenue from mortgages it wouldn't have touched a year ago, high-ratio loans stretched over three decades, thin equity cushions, and heavy exposure to pre-construction valuations in markets where appreciation has flattened or reversed.
The profit didn't follow the revenue. Net income dropped 22% year-over-year as Sagen's loss ratio climbed to 47%, meaning nearly half of every premium dollar collected went straight out the door to cover defaults. That ratio sat at 34% in the comparable quarter last year. The gap isn't an accounting quirk. It's the lag effect of 2025's high interest rates finally hitting households that renewed at payment levels 40% to 60% higher than their original terms. A borrower who locked in at 1.79% in May 2021 and renewed at 5.49% in June 2025 is only now showing up in Sagen's delinquency pipeline, twelve months into a payment they can't actually afford.
Why Longer Amortizations Amplify Insurer Risk
A 30-year amortization lowers the monthly nut for the borrower, which is the political appeal. For Sagen, it does something else: it slows equity accumulation to a crawl. A borrower putting 5% down on a $750,000 condo in Mississauga and amortizing over 30 years will owe roughly $712,000 after two years of payments, assuming a 5.2% rate. If that condo's value drops even 6%, the sale won't cover the loan balance, and Sagen eats the shortfall.
The math worked when home prices climbed 8% to 12% annually. It stops working when Greater Toronto resale prices are up 1.4% year-over-year and new condo inventory is sitting unsold. Claim severity, the dollar loss per default, has risen faster than the delinquency rate itself, because the gap between what's owed and what the property fetches at sale is widening in soft regional markets. Vancouver, Toronto, and their suburbs account for the bulk of Sagen's insured portfolio. Those are the same markets where pre-construction buyers are walking away from deposits rather than closing on units now worth less than the purchase agreement.
The New-Build Concentration Problem
Federal policy tied the 30-year option explicitly to new construction, aiming to juice housing supply by making builder inventory easier to finance. What it actually did was concentrate Sagen's incremental volume in the riskiest segment of the market: units bought off plans 18 to 36 months ago, often at peak pricing, now closing into a softer environment with thinner comps.
A resale home has a transaction history. A pre-construction unit has a developer's promise and an appraiser's desktop estimate. When the market turns, those appraisals get tested, and the results are showing up in Sagen's severity figures. The borrower who closes on a $680,000 two-bedroom in Oakville that appraises at $645,000 two months later is already underwater before the first payment clears, and they're carrying a 30-year amortization that won't build meaningful equity for years.
The volume story is real, Sagen is writing more business than at any point since the pre-pandemic boom. But volume priced into a softening market with minimal equity and maximal amortization isn't growth. It's exposure with a government backstop.
