Why Are Australian Banks Cutting Home Loan Rates While Westpac Predicts Another RBA Hike in August 2026?

Key takeaway: Westpac expects the Reserve Bank of Australia to lift the cash rate again at its 11 August 2026 meeting, up from the current 4.35%. Yet lenders have launched a fresh round of home loan discounting at the same time — an unusual window for borrowers to reprice their debt before the decision lands.

The Numbers at a Glance

Westpac Has Locked In Its August Rate Call

Westpac has become the clearest voice among the major banks in forecasting another cash rate increase at the RBA's 11 August 2026 meeting (Australian Broker, July 2026). The RBA left the cash rate unchanged at 4.35% at its June meeting, but annual inflation was still running at 4.0% in the year to May 2026 (ABS) — well above the RBA's 2–3% target band. That is the core of the hawkish case: until inflation shows convincing progress back towards target, the pressure on the Monetary Policy Board points up, not down.

Interestingly, the majors have diverged on how much further rates will rise, yet they have begun to converge on when borrowers should expect cuts (The Adviser, July 2026). In other words, even the banks forecasting more tightening see it as the last phase of the cycle rather than the start of a new one. The next major signpost before the August meeting is the quarterly CPI release on 29 July 2026.

Why Lenders Are Discounting Into a Rising Rate Cycle

Competition for high-quality borrowers is driving a fresh round of home loan discounting even as cash rate expectations rise (The Adviser, July 2026). That sounds contradictory, but it reflects how lenders actually price: the cash rate sets the funding backdrop, while the margin each lender charges above it is a commercial choice. In a slower housing market with fewer new loans being written, refinancers become the most contested customers — and lenders are willing to trade margin for volume to win them.

For borrowers, the practical effect is a widening gap between what existing customers are paying on older loans and what the same lenders are offering new money. History suggests these gaps do not stay open indefinitely, particularly if funding costs rise after a cash rate move.

"A discount war during a tightening cycle rewards borrowers who act early — pricing gaps this wide rarely survive the next rate decision."

What This Means for Borrowers: The MPFG View

For borrowers, the window between now and 11 August is a genuine opportunity to reprice existing debt — but the advertised discounts are typically reserved for salaried, full-documentation applicants. Self-employed borrowers, small business owners and anyone whose income does not fit neatly on a payslip often assume they are locked out of the refinancing round entirely. They are not. Alt Doc refinancing allows income to be verified through BAS statements, an accountant's letter or business bank statements instead, and non-bank lenders assess these applications on their merits rather than through a rigid template. MPFG Capital's refinance solutions support loans up to $7.5 million, with rates quoted on a "from" basis and every application subject to individual credit assessment. If a bank has already declined your refinance, or your income structure keeps disqualifying you from advertised specials, reviewing MPFG's product range is a sensible next step before the August decision changes the pricing landscape.

FAQ

Will the RBA raise interest rates in August 2026?

No outcome is guaranteed. Westpac expects an increase at the 11 August 2026 meeting, while other major banks hold different views on how much further rates will rise (The Adviser, July 2026). The quarterly CPI release on 29 July 2026 is the key data point most economists are watching before the decision.

Should I refinance before or after the RBA's August 2026 decision?

There is no universal answer — it depends on your loan size, current rate and personal circumstances. What is observable now is that lenders are actively discounting to win refinancers (The Adviser, July 2026), and if the cash rate rises in August, new-loan pricing may move with it. This is general information only, not credit advice.

Can self-employed borrowers refinance without payslips in Australia?

Yes. Alt Doc refinancing lets self-employed borrowers verify income using BAS statements, an accountant's declaration or business bank statements instead of payslips. Non-bank lenders such as MPFG Capital specialise in these applications, with all loans subject to credit assessment.
