Westpac’s August 2025 rate cut gives variable borrowers immediate relief, but the decision to fix or stay variable now depends on your view of the RBA’s next moves.

Is Westpac passing on interest rate cut?

Yes — Westpac confirmed it would fully pass on the RBA’s 0.25 percentage point rate reduction to both new and existing variable-rate borrowers. The bank made the announcement on 12 August 2025, joining Commonwealth Bank as one of the first big lenders to act after the central bank’s decision.

  • Westpac’s lowest variable rate after the cut fell to 5.34% (Canstar)
Why this matters

Westpac borrowers get the full benefit of the RBA cut — but only after a 14-day wait. Savers at Westpac, meanwhile, see their deposit rate change on 22 August, four days before mortgage holders catch up.

Westpac’s move matched its Big Four peers, signalling a coordinated pass-through. The implication: lenders who wait longer to pass on cuts often retain more profit margin on the spread.

What is Westpac’s current variable rate?

Five rate tiers, one takeaway: your loan-to-value ratio (LVR) still dictates how much you pay. Borrowers with more equity get significantly lower rates.

Westpac variable rate for LVR 70%-80%

  • Standard variable rate after cut is 6.54% p.a. for LVR >70%-80% (Westpac Home Loan Interest Rates)
  • Discounted owner-occupier variable rate: 6.44% p.a., comparison rate 6.45% p.a. (Westpac Home Loan Interest Rates)

Rates for LVR above 80%

  • Rates vary by LVR tier — higher LVR generally means higher rate (Westpac Variable Rate Home Loans)
  • Investor variable rate (discounted): 6.09% p.a., comparison rate 6.10% p.a. (Westpac Home Loan Interest Rates)

The catch: Westpac’s advertised rates sit above several smaller lenders’ offerings. If you have equity above 20%, comparison shopping could save you more than the cut itself.

Will mortgage rates drop to 3% again?

Short answer: unlikely in the near term. The RBA cash rate sits at 4.10% as of August 2025, and most analysts see a gradual easing path — not a return to the pandemic-era lows.

Historical mortgage rate trends in Australia

  • Variable rates peaked above 6.5% in 2023-2024 before the current easing cycle began (The Guardian)
  • The 3% variable rate era (2020-2021) required a 0.10% cash rate — not the current 4.10% (Reuters via U.S. News)

RBA cash rate forecast and impact

  • RBA cash rate currently 4.10% (Westpac Media Release)
  • Analysts do not forecast a return to 3% variable rates in 2025-2026 (Canstar)
The paradox

Every 0.25% cut makes a 3% mortgage feel further away, not closer. At the current cash rate, you’d need six more cuts of the same size just to bring the cash rate to 2.6% — still above the pandemic floor.

The implication: anyone waiting for 3% mortgages risks overpaying while they wait. The new normal looks like 5-6% variable rates for the foreseeable future.

Should I fix for 2 or 5 years now?

Three rate profiles, one pattern: fixed rates are pricing in future cuts, but they’re not cheaper than today’s variable offers. The decision hinges on how much certainty you’re willing to pay for.

Here is how Westpac’s fixed rates compare to its variable rate after the August 2025 cut.

Westpac fixed rate comparison vs variable after August 2025 cut
Metric Westpac 2-year fixed Westpac 5-year fixed Westpac variable (LVR 70-80%)
Rate p.a. ~6.29% ~6.49% 6.54%
Comparison rate p.a. ~6.30% ~6.50% 6.55%
Rate trend outlook Likely to fall if RBA cuts further Locked above current variable May decrease with RBA moves
Flexibility Limited — break costs apply Limited — high break costs Full — no lock-in

Pros of fixing for 2 years vs 5 years

Upsides

  • 2-year fixed: lower rate than 5-year; if rates fall, you’re back to variable sooner
  • 5-year fixed: total payment certainty for half a decade

Downsides

  • 2-year fixed: if RBA cuts quickly, you’re locked above market in year 2
  • 5-year fixed: pays a premium for certainty; break costs can run thousands

Current fixed rate offers from Westpac

  • Fixed rates are higher than variable in current environment (Canstar)
  • Locking in a low rate may not be beneficial if variable rates continue to fall (The Guardian)

The trade-off: fixing protects you from rate rises, but today’s fixed rates already bake in expectations of further cuts. If the RBA cuts again in 2026, variable borrowers win.

Is Westpac dropping interest rates?

Yes — Westpac cut variable rates by 0.25% p.a. in August 2025. Whether more cuts follow depends entirely on the RBA’s inflation data and labour market readings.

Will there be more cuts in 2025?

  • Westpac cut variable rates by 0.25% p.a. in August 2025 (Westpac Media Release)
  • Further cuts depend on RBA decisions (The Guardian)
What to watch

The RBA’s next decision in September 2025 will set the tone. If inflation stays sticky, the pause could extend into 2026 — leaving variable borrowers happy they cut now, but not yet celebrating a return to low rates.

The pattern: for Westpac borrowers, the question isn’t whether more cuts come — it’s when. The RBA’s 4.10% cash rate leaves room for at least one more cut this year if data cooperates, but no one is betting on a rapid descent.

Quotes

“Westpac today announced it would reduce home loan variable interest rates by 0.25 percentage points for new and existing customers.”

— Westpac media spokesperson, 12 August 2025 (Westpac Media Release)

“The Reserve Bank’s decision to lower the cash rate reflects improving inflation data, but the board remains cautious about the outlook for services inflation.”

— RBA governor, commentary on cash rate decision (The Guardian)

Westpac’s full pass-through of the RBA cut gives borrowers a genuine reprieve, but the 14-day wait means cash-flow relief arrives later than CBA’s 22 August effective date. The decision to fix or stay variable now hinges on whether you believe the RBA’s next move is another cut — or a long pause.

For Australian mortgage holders, the choice is clear: stay variable and bet on further easing, or fix for 2-5 years and pay a premium for certainty. The window for switching fixed is closing as rates adjust downward.

Frequently asked questions

How does Westpac’s variable rate compare to CBA’s after the cut?

Both banks cut by 0.25% p.a. in August 2025. CBA’s rate took effect on 22 August, while Westpac’s started on 26 August. The rates themselves are broadly comparable for standard variable products, though Westpac’s lowest promotional rate fell to 5.34% vs CBA’s comparable offer.

Will Westpac’s fixed rates change after the variable cut?

Westpac may adjust fixed rates in response to market expectations of future RBA moves, but fixed rates are currently above variable rates. Any change would depend on wholesale funding costs and the bank’s pricing strategy.

Does the Westpac rate cut apply to Rocket Repay loans?

The 0.25% cut applies to variable-rate home loans including Rocket Repay, as it’s a variable-rate product. Check your specific loan terms or contact Westpac to confirm the new rate applies to your product.

How much will my monthly repayment change after the Westpac cut?

For a $500,000 loan at the standard variable rate, a 0.25% cut reduces monthly repayments by roughly $75. Use Westpac’s repayment calculator for your specific loan amount and rate.

Is it better to switch to a fixed rate now?

With variable rates at 6.54% and fixed rates slightly higher, fixing locks in a premium over current variable rates. If you expect further RBA cuts, staying variable may save you money over 2-5 years.

What LVR tier do I need to get the best Westpac variable rate?

The best variable rates are typically available for LVRs of 70% or below. Higher LVRs attract higher rates. Westpac’s discounted owner-occupier rate of 6.44% applies to lower-LVR borrowers.

Are there any fees to refinance to Westpac’s new variable rate?

Refinancing to Westpac may involve establishment fees, valuation fees, and discharge costs from your current lender. Westpac occasionally offers cashback deals for refinancers — check current offers before switching.

What is the cheapest home loan interest rate in Australia?

As of August 2025, some non-bank lenders and smaller mutuals offer variable rates below 6.00% p.a., with a few dipping to 5.50% or lower for low-LVR borrowers. Westpac’s best rate after the cut is 5.34% on its lowest promotional product.

Bottom line: Westpac’s 0.25% rate cut is a genuine saving for variable borrowers, but at 6.54% standard variable it’s still far from the pandemic-era lows. Homeowners with equity should compare smaller lenders, while those without may find that fixing at 6.29% for 2 years buys peace of mind — though they could overpay if the RBA cuts again in 2026.
