Westpac Flags Higher Rates and Costly Builds as New Test for Australian Borrowers

Westpac has flagged a new set of challenges for Australian borrowers as higher interest rates combine with soaring construction costs to squeeze housing affordability. Despite a resilient economy, borrowers seeking relief from elevated mortgage repayments face an extended wait, according to the bank's latest analysis.

The Double Squeeze: Rates and Build Costs

Australia's construction sector continues to face cost pressures from labour shortages, materials inflation, and supply chain disruptions. Combined with the RBA's cash rate at 4.10% — following the March 2026 decision — this creates a challenging environment for:

• New home builders: Higher borrowing costs plus elevated build costs reduce the viability of new construction projects
• Property developers: Rising input costs can erode margins on development finance
• Upgraders: Renovating or extending an existing property now costs significantly more than pre-pandemic levels

Rate Relief Pushed Further Out

Westpac's economists suggest that borrowers hoping for RBA rate cuts in 2026 may need to adjust their timelines. While Australia's economy has held up better than feared, persistent inflation and tight labour markets reduce the urgency for rate reductions.

For self-employed borrowers and small business owners — who make up a significant portion of MPFG's client base — this environment underscores the value of flexible non-bank lending products that aren't constrained by the same stress-testing criteria as major banks.

How Non-Bank Lenders Compare

For borrowers navigating a high-rate, high-cost environment, non-bank options provide critical flexibility — particularly for those whose income doesn't fit into a payslip template.

Key Takeaways for Property Buyers

The Westpac analysis reinforces that 2026 is a market where borrower preparation matters. Knowing your options before approaching lenders — including non-bank alternatives — gives you negotiating power and reduces the risk of rejection.

• Build costs show no sign of retreating in the near term
• Rate cuts remain uncertain; plan around current rates, not anticipated cuts
• Non-bank lenders assess income more flexibly for self-employed applicants

FAQ

Q: Will the RBA cut rates in 2026?

A: Most economists, including those at Westpac, suggest rate cuts are not imminent. The May 2026 RBA board meeting is the next key decision point. Plan based on current rates.

Q: How do construction loans work with non-bank lenders?

A: Non-bank lenders can offer construction finance with progressive drawdowns tied to build milestones. Terms and LVR limits vary by lender and project type.

Q: Does the RBA cash rate directly affect non-bank loan rates?

A: Non-bank lenders set their own rates based on their funding costs, which can differ from the RBA cash rate. Some products may be less directly linked to RBA movements.
