CBA’s Ahead Share Slipped to 85% and Offsets Fell $3bn. That Is the Crack, Not the 50th Bank With a 5-Handle

1. The number the rate wrap left out

The trade press will lead with the 50th bank. Tindall’s own line is clean: it is the 50th bank to offer at least one variable rate starting with a five since the Reserve Bank hiked in May — over 60 per cent of the lenders in Canstar’s database. Bank Vic’s cut took its lowest rate under 6 per cent. Pacific Mortgage Group holds the lowest variable on the database at 5.69 per cent. Those are facts in a wrap. They are not a panel instruction, and they are not this briefing’s lead.

In the same piece, Tindall turned to the existing book. “While Australia’s three biggest banks have seen a retreat in new mortgage applications, CBA’s full year results presented the slightest of cracks in its existing customers in the face of higher rates.” The cracks she named were two: 85 per cent of residential mortgage customers remain ahead on repayments, down from 87 per cent in December last year; offset balances fell to $94 billion from $97 billion over the same period.

This desk has already written the CBA FY26 applications story. It will not be rehashed as the lead here. Tindall’s applications line is directional — a retreat at the three biggest banks — and that is as far as this piece will take it. The working question is not how many new files the majors took. It is how many of the files you already hold look like a two-point slip and a thinning offset.

2. What Canstar actually printed

Home-loan pricing continued to shift unevenly in the week Australian Broker dated 18 August 2026. No fixed-rate moves. Fresh movement on variable.

Two lenders lifted four owner-occupier and investor variable rates by an average of 0.15 per cent. Three lenders went the other way, cutting five variable rates by the same average margin. The average variable rate for owner-occupiers on principal and interest now sits at 6.64 per cent. At the pointy end, Pacific Mortgage Group holds the lowest variable on Canstar at 5.69 per cent. The number of sub-5.75 per cent rates slipped to two, down from three the previous week.

Tindall singled out Bank Vic: “No move on the fixed rate front this week, however, three lenders took the knife to variable — including Bank Vic which took its lowest rate under the coveted 6 per cent mark.” Then the milestone: “It’s the 50th bank to offer at least one variable rate starting with a 5 since the RBA hiked rates back in May – that’s over 60% of the lenders in our database.”

Name those lenders as facts in a wrap. Do not turn them into a recommendation. A lowest-on-Canstar print is a shop-window observation. Policy, serviceability, accreditation, turnaround and the client’s existing loan are the file. This piece will not tell you where to lodge.

3. Two points and three billion

Eighty-five per cent remain ahead. That sentence is easy to read as comfort. Read the other half: 15 per cent of a major’s residential mortgage customers are not ahead on repayments. Two points off 87 is not a collapse. It is a direction. Offsets at $94 billion, down $3 billion from $97 billion since December, is the same direction in dollars.

Tindall called it the slightest of cracks, and she said the figures were not yet cause for alarm. Both can be true. A crack is not a break. A crack is also not noise. Ahead, in the way a bank prints it, is extra repayments and offset. When the share of customers who are ahead slips, and the stock of offset falls, some households have stopped building buffer and started using it. That is a conversation you can have while they are still ahead. It is a different conversation once they are not.

This piece will not invent an arrears figure for CBA. Australian Broker did not print one in the 18 August wrap. If a later results deck or a later Canstar note names a basis-point print, use that source. Do not back-fill one here so the crack looks louder.

4. Refinance and negotiate — the only two levers named

Tindall’s operational line is short. Refinancing and negotiating remain the most effective levers for borrowers at this stage. Some lenders publicly advertise cuts for new customers. Others prefer to negotiate privately.

That split is the week. The 50th 5-handle is the advertised cut. Bank Vic under 6 per cent is the advertised cut. The privately negotiated rate does not appear on Canstar’s lowest-rate line. A client who is still ahead, still sitting on an unreviewed variable, and still treating the shop window as someone else’s problem, is the file the wrap is actually about — even when the headline is the 50th bank.

Refinance is not a product pick. It is a process: current rate, remaining term, break costs if any, the new comparison, serviceability at today’s assessment, and a named fallback if the first path stalls. Negotiate is not a script that says “match the 5.69”. It is a conversation with the existing lender that uses the shop window as evidence, not as the destination. Some of your clients will stay. Some will move. The failure mode is the client who does neither because nobody called.

Do not send the book to one lender because they printed the lowest variable this week. Sub-5.75 per cent offers slipped to two from three. Shop windows move. A habit built on this week’s lowest print is a single point of failure with a 5-handle on it.

5. What the 15 per cent who are not ahead means

Not-ahead is not a diagnosis you invent from a headline. It is a state you confirm on a file: scheduled repayment only, no extra, offset thin or gone, or already behind. CBA printed that 15 per cent of its residential mortgage customers are in that broader “not ahead” bucket. It did not, in this wrap, tell you how many of those 15 are in hardship, how many are exactly on schedule, or what the arrears rate is. Do not fill the gap.

The useful reading for a working desk is one step earlier. The two-point slip is people leaving the ahead bucket. The $3 billion is people drawing the offset. Those people are still, in the 85, ahead. They are the ones a broker can still help with a refinance or a negotiation before the file becomes a not-ahead conversation. That is why Tindall can say “not yet cause for alarm” and still be pointing at a list you should pull this week.

Your book is not CBA’s book. It may already show the same drift. It may not. Guessing is how a CRM stays a CRM. Sorting last quarter’s live files into four bands is how it becomes a retention list.

6. Four bands for the live book

If you cannot name the mix, that is the finding. Pull the live residential book. For each file: extra repayments, yes or no; offset balance versus six months ago; and whether they are on, ahead of, or behind schedule. Dollar share of the book in each band pays the bills. File-count share is how many conversations you owe.

Still well ahead. Extras are still going in, or the offset is still building. This is not a reason to skip the rate review. The shop window moved. An unreviewed variable on a fat buffer is still an unreviewed variable. Call them so the first conversation is not the day the extras stop.

Ahead, but thinning. Still ahead. Offset down, extras stopped, or both. This is the CBA crack in miniature. Refinance or negotiate this week, while there is still a buffer to work with. Do not wait for the file to fall into the 15.

On schedule. No extras. No material offset. Not behind. There is no buffer to spend. The lever is the rate, and Tindall named the two ways to pull it. This is not a hardship file. It is a file with no shock absorber.

Not ahead. Behind schedule, or already in a hardship conversation. This is not a 5-handle shopping trip. It is responsible lending, aggregator process, and the existing lender’s hardship path. Do not use a Canstar lowest-rate print as the opening line.

The tool below walks the same four bands. The sort takes an afternoon. The conversation with the thinning files is the week.

7. Three actions this week

1. Sort the live book. Ahead, thinning, on-schedule, not-ahead. Extra repayments, offset versus six months ago, schedule position. If you cannot produce the list, that is the finding. The 50th 5-handle can wait.
2. Open the thinning files first. Refinance or negotiate — the two levers Tindall named. Write the current rate, the remaining term, and whether the existing lender negotiates privately or only advertises for new customers. Do not name a destination lender from a wrap.
3. Call the on-schedule book before it thins. No buffer means the next rate or the next life event is the event. A rate review now is cheaper than a not-ahead file later. Keep a named fallback path on every file you touch, so a stall is not a dead end.

Tindall is right that 85 per cent still ahead is not yet cause for alarm, and right that refinancing and negotiating are the levers. The unfinished sentence is that a channel which can see a two-point slip and a $3 billion offset print, and then spends the week arguing about the 50th 5-handle, has chosen the shop window over the book it already holds.
