A non-bank lender dropped its advertised variable rate to 6.04 per cent this week, joining twenty-nine other institutions that have trimmed at least one mortgage product since the start of June. The catch: every discount applies only to new customers, leaving existing borrowers on standard rates that can sit 50 to 100 basis points higher unless they pick up the phone or move their loan to another bank.
With the RBA holding the cash rate steady and no cut expected inside twelve months, out-of-cycle competition is the only rate relief on offer. The question is whether the difference between new-customer rates and loyalty rates is large enough to justify the paperwork and the upfront cost of refinancing.
The two-tier mortgage market
New-customer variable rates at major lenders now range from 6.04 per cent to around 6.09 per cent, while standard variable rates for existing borrowers often sit between 6.50 per cent and 6.80 per cent. On a $600,000 loan, a 60-basis-point gap translates to roughly $3,600 a year in additional interest, or $300 a month that loyalty customers hand over for doing nothing.
The spread exists because banks price for acquisition, not retention. A new borrower generates a book-growth metric; an existing borrower generates no headline and no bonus. Smaller lenders and non-banks use aggressive new-customer pricing to pull market share from the big four, which have yet to move their advertised rates but are under mounting pressure as loan-book growth slows. One major bank reported a 15 per cent drop in new home-lending applications in the June quarter, and total residential mortgage debt, now $2.51 trillion, grew by just $17.9 billion in June, the slowest pace in six months.
The refinancing ledger
Switching costs matter. Discharge fees, application fees, valuation fees and settlement fees typically add up to $1,000 to $1,500. Some lenders waive application fees or offer cashback to offset the upfront hit, but borrowers need to model the payback period.
Example: a borrower with a $500,000 loan on a 6.70 per cent standard variable rate refinances to a 6.10 per cent new-customer rate. The annual interest saving is roughly $3,000. If switching costs $1,200, the borrower recovers the outlay in under five months and banks $1,800 net in year one. Over three years, the cumulative saving exceeds $9,000, assuming rates hold.
The calculus shifts if the borrower plans to sell within twelve months, if the new lender’s honeymoon rate reverts to a higher ongoing rate after two years, or if the borrower’s loan-to-value ratio has crept above 80 per cent and lenders mortgage insurance becomes a line item. Run the numbers with actual quotes, not advertised rates, since credit scores, employment type and deposit size all move the needle.
Callout: In plain English
Refinancing means closing your current home loan and opening a new one with a different lender. You pay off the old loan with funds from the new loan, and the new lender registers a mortgage over your property. The process takes three to six weeks and requires income verification, a property valuation and a credit check. If your circumstances have changed since you took out the original loan, lower income, higher expenses, a second property, serviceability can be tighter the second time around.
Haggling as the low-friction alternative
Borrowers who call their current lender and ask for a rate review often extract 20 to 40 basis points without switching. The script is simple: “I’ve been offered [specific rate] by [specific competitor]. Can you match it or get close?” Banks have retention teams whose job is to prevent defection, and a discount that keeps the customer in-house costs the bank less than losing the loan and the cross-sell opportunity.
Success rate varies. Borrowers with clean repayment history, equity above 20 per cent and a competitor quote in hand tend to get the best outcome. Borrowers who threaten without a genuine alternative quote, or who have missed payments in the past twelve months, get less traction. The retention discount typically applies as a margin reduction on the standard variable rate, not a switch to the new-customer product, so the final rate may still sit above the lowest advertised offer, but the difference narrows, and the borrower avoids switching costs entirely.
Who wins in this pricing cycle
Borrowers with large loan balances, strong equity positions and the time to compare five or six lenders come out ahead. A 50-basis-point saving on a $1 million loan is $5,000 a year; even after switching costs and adviser fees, the net gain is material.
Borrowers with small balances, tight equity or complex income (casual work, recent self-employment, offshore income) face higher friction. Switching costs eat a larger share of the annual saving on a $300,000 loan, and some lenders tighten serviceability or refuse to lend at all if employment type doesn’t fit the policy matrix.
First-home buyers entering the market now benefit from the competition, since they qualify as new customers by definition. Investors refinancing to improve cashflow also gain, provided the rental income and existing debt service don’t push them past the serviceability buffer.

Pressure points and what could shift
Competition is rising because loan-book growth is slowing and banks need volume to hit targets. If property turnover lifts, either from falling rates or from pent-up demand breaking loose, the pricing war could accelerate further. If turnover stays flat or declines, banks may pull back new-customer offers and widen the gap between acquisition rates and retention rates, betting that inertia keeps most borrowers in place.
Regulatory settings also matter. APRA’s serviceability buffer sits at 3 percentage points above the loan rate, meaning a borrower applying at 6.10 per cent must prove they can service the loan at 9.10 per cent. If wage growth stays subdued and living costs stay elevated, fewer borrowers will clear the buffer on refinance, and competition will concentrate among those with the cleanest balance sheets.

What to do if you have a mortgage
Pull your latest loan statement and note the interest rate, the remaining balance and the monthly repayment. Compare your rate to the lowest new-customer offers from at least three lenders (use comparison sites, but verify the rate with the lender directly, since advertised rates often require specific LVR bands or offset features).
If the gap is 50 basis points or more and you have at least $400,000 outstanding, model the refinancing cost and the payback period. If the payback is under six months, switching makes sense. If the gap is 30 to 50 basis points, call your current lender first and ask for a retention discount. Use a competitor quote as leverage. If the lender moves your rate within 20 basis points of the best offer, staying put avoids the refinancing hassle. If the lender won’t move, or moves less than 20 basis points, refinance.
If you have less than $300,000 outstanding, or if you plan to sell within eighteen months, haggling is the better play unless the rate gap is extreme. Switching costs consume too much of the annual saving on smaller balances, and the friction isn’t worth the net gain.
