Your Bank Raised Your Rate — So Why Are Lenders Cutting Rates for New Customers?

Your mortgage went up — while some new home loan rates went down

The Reserve Bank says variable mortgage rates increased by nearly 75 basis points between January and June 2026 as lenders passed through this year's cash-rate increases.

Yet the RBA also says that, since June, some lenders have cut selected advertised variable mortgage rates by 20 to 30 basis points. Some fixed rates were reduced as well.

Canstar's rate tracking makes the same pattern clear. As at 10 August, 49 lenders had at least one variable rate below 6%, up from 38 at the start of June. It also recorded 31 lenders cutting new-customer variable rates since June.

That does not mean every home loan rate in 2026 is falling. It means lenders are pricing selectively.

Because a new mortgage customer is valuable

A home loan is not a short relationship for a bank.

A borrower might stay for 20, 25 or 30 years. Over that time there may also be offset accounts, transaction accounts, investment lending and future borrowing.

That makes winning a new mortgage commercially valuable. If housing lending slows, lenders compete harder for the borrowers who are still entering the market.

Banks do not always reward loyalty with their sharpest rate

This is the uncomfortable part for existing borrowers.

Canstar surveyed 2,891 mortgage holders in 2026 and found 52% had never changed home loan providers. Only 6% had switched in the previous 12 months.

That does not mean every borrower who has stayed with the same lender is overpaying. In fact, broad RBA data shows average rates on new and existing variable loans have been relatively close.

But averages can hide a poor individual deal.

A borrower who has not requested repricing for years may have paid down the loan, built more equity and become a lower-risk customer without seeing any automatic improvement in their rate.

Ask your current lender to reprice first

Refinancing does not need to be the first move.

If the existing loan structure still suits you, a pricing review with your current lender may be the fastest and cheapest place to start.

A 5-something rate on a website is not automatically your rate

Canstar reported that 60% of lenders in its database had at least one variable rate starting with a 5 as at 10 August.

That's useful evidence of competition, but it is not the same thing as saying 60% of lenders will offer every borrower a sub-6% loan.

Advertised home loan rates can depend on:

• whether the loan is owner-occupied or investment;
• principal and interest versus interest-only repayments;
• loan-to-value ratio;
• loan amount;
• property type;
• product features;
• new-customer eligibility; and
• the lender's credit policy.

A lower home loan rate can still be the wrong refinance

Interest rate matters. Of course it does.

But a refinance should be assessed as a whole loan rather than a single percentage on a comparison page.

If you want to test how a different rate could change your repayments without pretending the rest of the loan does not exist, our Mortgage Lab lets you compare rates, remaining terms and offset scenarios.

Lower repayments do not always mean a cheaper mortgage

This is one of the easiest refinance mistakes to make.

Imagine you have 22 years left on your existing home loan. You refinance and the new lender sets up another 30-year term.

Your monthly repayment may fall. That can look like an immediate win.

However, you may now be paying interest for up to eight additional years unless you deliberately keep repayments higher or shorten the term.

A shiny incentive does not rescue a mediocre loan

Refinance cashback offers have also returned in parts of the market, with some current offers reaching several thousand dollars depending on eligibility.

They can help cover switching costs. They can also distract from a higher rate or weaker product.

The cashback should be included in the calculation, not allowed to become the calculation.

No — your individual mortgage rate can change without a cash-rate cut

The RBA held the cash rate at 4.35% on 11 August 2026.

What happens next remains uncertain. The RBA's August Statement noted that markets were pricing roughly a half chance of another increase by the end of the year, while most economists it tracks expected the cash rate to remain unchanged over the following year.

Trying to wait for the perfect RBA decision can therefore turn into trying to predict the future.

Your rate may improve because:

• your existing lender agrees to reprice;
• another lender is competing harder for new business;
• your LVR has improved;
• your loan becomes eligible for a different product; or
• your borrowing position has changed.

Finding a better rate and qualifying for it are two different things

This is where the current market gets particularly interesting.

You may find a lower rate and still fail the new lender's serviceability, valuation or credit assessment.

That is exactly the issue behind mortgage prison: a borrower can keep paying the existing mortgage but still struggle to qualify for a cheaper replacement loan.

So the rate review and the refinance assessment need to happen together.

Home loan rates in 2026 are not moving in one neat direction

Existing variable mortgage rates rose as the RBA increased the cash rate.

At the same time, mortgage demand has softened and lenders are competing for new customers. That has led some lenders to cut selected new-customer variable and fixed rates.

Neither of those statements cancels out the other.

The practical lesson is much simpler: do not assume the rate you already have is the best your lender can offer, and do not assume the sharpest advertised new-customer rate is automatically the right refinance for you.
