Australia's residential mortgage-backed securities market is seeing a new AUD1 billion issue tied to conforming home loans from RESIMAC Limited. The transaction includes floating-rate notes backed by 1,704 borrowers, with support for yen-denominated class A2 notes through a balance-guaranteed currency swap.
Highlights
- Fitch assigned expected ratings to RESIMAC Triomphe Trust, RESIMAC Premier Series 2026-3 mortgage-backed floating-rate notes issued by Perpetual Trustee Company Limited.
- The AUD1 billion collateral pool consists of 1,704 Australian loans with a weighted-average current loan-to-value ratio of 66.0% and 23.9% self-employed borrowers.

Rating assignment and transaction structure
As reported by Fitch Ratings, RESIMAC Triomphe Trust, RESIMAC Premier Series 2026-3 has received expected ratings for mortgage-backed pass-through floating-rate notes to be issued by Perpetual Trustee Company Limited as trustee of the series-segregated trust.The notes are backed by a pool of first-ranking Australian residential conforming full-documentation mortgage loans originated by RESIMAC Limited. As of the 14 October 2026 cut-off date, the collateral pool totals AUD1 billion and consists of 1,704 obligors, with a weighted-average current loan-to-value ratio of 66.0% and a weighted-average indexed current loan-to-value ratio of 62.7%.
Fitch says key rating drivers include credit enhancement buffers expected to cover 'AAAsf' losses, with analysis reflecting the pool's weighted-average unindexed loan-to-value ratio, the 23.9% share of self-employed borrowers and a significant portion of investment loans. The agency also says foreign-exchange risk for the yen-denominated class A2 notes is mitigated by a balance-guaranteed currency swap, while operational risks remain low because of RESIMAC's long operating history.
As highlighted earlier, Fitch rated Hainan Rubber’s proposed Perpetual securities BBB- due to subordination and coupon-deferral features.
