Mortgage rate cuts spread in August, but the typical rate barely moved

Nearly nine in every 10 advertised-rate changes recorded during August were cuts, but the action came from challengers and second-tier lenders while the Big Four and Macquarie largely stood still.

Australian lenders continued to trim selected home loan rates in August, but the reductions were not broad enough to move the middle of the market for a common owner-occupier variable loan.

Rate Challenge's review of advertised pricing from more than 100 lenders found that almost 90% of the like-for-like rate changes recorded during the month were reductions. The typical change among rates that moved was a cut of about 0.15 percentage points.

That activity happened without help from the Reserve Bank. The RBA left the cash rate at 4.35% on 11 August, after lifting it by a total of 0.75 percentage points earlier in 2026. The result was a two-speed market: sharper offers appeared in parts of the market, while typical pricing remained much steadier.

August was a month of selective discounting, not a market-wide reset. Rate Challenge analysis

Most of the movement was down

Among matched advertised rates that changed during August, 89.8% moved lower and 10.2% moved higher. Put another way, reductions outnumbered increases by almost nine to one.

The size of a typical move was modest. The median change among rates that moved was a reduction of 0.15 percentage points—the equivalent of a rate falling from 6.24% to 6.09%.

On a $600,000 principal-and-interest loan with 30 years remaining, that difference would reduce the estimated repayment by about $58 a month, assuming the rate applied to the whole loan and everything else stayed the same.

Which lenders made the biggest moves?

The month's largest movements were concentrated among a relatively small group of lenders. Some cut broadly, while others moved different parts of their range in opposite directions.

Selected examples from matched opening and month-end advertised-rate records. A movement may apply only to the loan type and conditions shown, not the lender's entire range.

AMP produced the largest individual advertised-rate cut in the matched data: 0.70 percentage points on a selected owner-occupier interest-only loan. The comparison rate on the same scenario fell by a smaller 0.26 percentage points. Credit Union SA cut numerous fixed rates, including 0.45 percentage points from the three-year owner-occupier package highlighted above.

Community First Bank made one of the broadest downward repricings, cutting matched advertised rates by 0.15 to 0.20 percentage points. Horizon Bank, Regional Australia Bank and GMCU also made multiple reductions.

Not every lender moved in one direction. Bendigo Bank cut selected higher-LVR owner-occupier pricing but increased some investor and interest-only rates. Aussie lowered selected interest-only rates while lifting other principal-and-interest rates. MoveBank increased several fixed investment rates by 0.20 percentage points.

Major-bank watch

The Big Four and Macquarie sat out the repricing

ANZ, Commonwealth Bank, NAB, Westpac and Macquarie Bank recorded no change in either the advertised rate or comparison rate across the matched loan scenarios between Rate Challenge's opening and month-end snapshots. ANZ Plus was also unchanged.

This does not rule out changes to offers, discounts or lending policy outside the matched rate records. It does show that the visible August rate movement was overwhelmingly driven by lenders outside that group.

Comparison rates told a more complicated story

The advertised rate and comparison rate did not always move together. That matters because the comparison rate incorporates certain fees and a standard loan calculation, while fixed and interest-only comparison rates can also reflect what happens after the initial period.

For example, the comparison-rate reduction on GMCU's one-year fixed investor loan was only 0.04 percentage points despite a 0.40-point headline cut. On selected Credit Union SA investment packages, the advertised fixed rate fell while the comparison rate increased. The dataset records the movement but does not establish whether it resulted from fees, revert-rate assumptions or another pricing input.

The practical conclusion is simple: a large headline cut can be meaningful, but it should not be treated as an equal-sized reduction in the loan's overall cost.

Why the headline rate held steady

More cuts did not mean lower rates everywhere

The typical advertised variable rate for a $600,000 owner-occupier refinance at 70%–80% LVR was 6.24% at both the beginning and end of August in the Rate Challenge sample. Its typical comparison rate edged down slightly, from about 6.40% to 6.38%.

This is not a contradiction. A market can record many cuts without its median falling when lenders change only selected products, borrower segments or loan-size tiers. New offers can become more competitive while a large share of the market remains unchanged.

The RBA described a similar pattern in its August review of financial conditions. It said some lenders had reduced selected advertised variable rates since June amid strong competition, while the effect on rates actually paid across all mortgages remained uncertain.

What the August market means for mortgage holders

For existing borrowers, the main message is that a competitive market does not automatically produce a lower repayment. Many advertised cuts are aimed at new customers or particular loan types. A borrower can therefore remain on an older rate even as sharper offers appear elsewhere.

The gap between a borrower's rate and the rates available to similar new customers is often more useful than the number of rate cuts reported in a month. Deposit or equity, loan size, property type, income and lender rules can all change the price available to an individual.

For buyers, August offered more sub-6% variable options, but the lowest headline rate should not be read as the best loan for every borrower. Fees, offset and redraw features, serviceability rules and the comparison rate can materially change the overall value.

Investor pricing remained higher

Investor variable rates generally remained above comparable owner-occupier rates. In the Rate Challenge sample, the typical variable rate for a $600,000 investor refinance at 70%–80% LVR eased from about 6.44% to 6.40% over the month.

Interest-only repayments can reduce the initial monthly outlay, but they do not reduce the loan balance during the interest-only period. That distinction matters when comparing monthly repayment estimates in the explorer.

The wider market tells the same story

Public data supports the broad direction of the Rate Challenge findings. Canstar reported on 10 August that 49 lenders offered at least one variable rate below 6%, up from 38 at the start of June, and that 31 lenders had cut new-customer variable rates over that period.

The RBA's August Statement on Monetary Policy also pointed to selected variable-rate reductions by smaller lenders and described competition in housing lending as strong. At the same time, the RBA held the cash rate at 4.35% because inflation remained too high.

What to watch next

Competition may matter more than the next RBA headline

The next scheduled RBA monetary policy update is on 29 September. Until then, changes in advertised mortgage rates may continue to be driven by lender funding costs, competition and appetite for particular borrowers—not only by the cash rate.

Sources and methodology

Rate Challenge compared opening and month-end advertised-rate snapshots for more than 100 Australian lenders. Like-for-like loan scenarios were matched before a movement was counted. The interactive explorer shows rounded, anonymous summaries and suppresses combinations with limited market coverage.
