In some key markets, it is a real challenge to obtain an accurate measure of success and growth trends.  The residential home loan refinance market is a case where there is plenty of competition, but it is very difficult to discern which companies are doing better in key geographic areas and how to benchmark performance.  The data that would provide these insights is restricted, mainly for compliance reasons.

PEXA, which manages Australia’s largest digital property exchange, now has a solution.  The Residential Home Loan Refinance index allows lenders to compare their refinance portfolio movement with the national or state metro or regional markets.

The Refinance index provides insights into where relative market share is growing and where an existing portfolio may be at risk.  Residential home loans are a crucial component of Australian banks’ profitability.  Knowing where a lender is thriving and where there is a retention challenge is essential in managing the overall portfolio growth.

As a guide to the importance of this asset category, Residential property is the single largest investment asset class in Australia:

  • $8.9 trillion residential property market
  • $2.5 trillion stock total market cap
  • $3.1 trillion Superannuation approx.

(All as of June 2021*)

So, clarity on housing market behavior is critical for homeowners, investors, government policymakers and financial institutions.

As Australia’s most prominent digital property settlement network, PEXA can provide deep insight into Australia’s housing sector transactions.
