RMBS ETF: An Australian first

In an Australian first, investors are now able to access a dedicated Australian residential mortgage-backed securities ETF.

A residential mortgage-backed security is a type of fixed-income bond secured by a pool of residential home loans, where payments of principal and interest on the bonds are funded by the payments made on the underlying mortgages. 

Residential mortgage-backed securities are one of Australia’s fastest-growing fixed income asset classes, surpassing a landmark A$50 billion of issuance in 2024.

Australian residential mortgage backed securities have been used by fixed income investors as a diversifier within their bond portfolios. Traditionally, these have primarily been available to institutional or 'sophisticated' investors, with very high minimum investment amounts.

Historically, Australian RMBS exposure has primarily been accessed as a sleeve within diversified fixed income strategies, rather than as a standalone investment. This is due to the complexity, lower liquidity, and specialist expertise required to manage RMBS effectively. For most investors, exposure has typically come through multi-sector credit or income funds where RMBS plays a supporting role for yield and diversification.

That is changing. For the first time all types of Australian investors are able to access this asset class on the ASX via the VanEck Australian RMBS ETF (RMBS).

RMBS offers investors a transparent, liquid AAA credit rated investment opportunity with a potential yield uplift.
