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.
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.
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.
