Westpac has emerged as a principal driver of renewed activity in Australia’s residential mortgage-backed securities market, helping to generate a faster-than-usual start to the 2026 securitisation calendar following an exceptionally busy 2025. Issuance of RMBS — debt instruments backed by pools of home loans — lagged only in the quietest seasonal moments before Westpac’s recent transactions helped lift market sentiment and deal flow.

The bank’s active participation comes after a record-breaking phase of structured credit issuance that underpinned strong investor demand for Australian securitisation products and prompted issuers to return to the market earlier in the year than is typical.

Westpac’s involvement has helped set a positive tone after a prolonged period in which the market opened slowly in January, a month that traditionally sees limited volume.

The broader Australian securitisation market posted robust results in recent years, with residential mortgage-backed securities at the core of that momentum.

Data compiled by industry bodies show that Australian structured finance issuance, including RMBS, remained elevated into late 2025, reflecting heightened investor appetite and improved pricing conditions compared with prior cycles.

Market insiders point to strong underlying housing loan demand, supportive credit conditions and improved relative value of RMBS as factors that encouraged banks such as Westpac to re-engage with significant issuance.

Westpac’s structured finance and securitisation unit, which maintains an active secondary market presence and arranges term asset-backed bond issues, has positioned the bank to capitalise on this resurgence.

Its ability to underwrite and distribute RMBS transactions has been amplified by supportive market liquidity and investor interest in higher-quality credit linked to Australian home loan portfolios.

Observers say continued engagement by major banks could sustain momentum in the RMBS market through 2026 if conditions remain favourable.
