Why Some Lenders Are Cutting Variable Rates While the RBA Hikes — What Australian Borrowers Need to Know
If you’re paying a variable home loan rate right now, today’s news is worth reading carefully. On 5 May 2026 — the same day the Reserve Bank of Australia (RBA) is widely expected to lift the official cash rate to 4.35% — at least one non-major lender moved in the opposite direction, slashing variable rates by up to 0.15 percentage points for new customers.
It sounds contradictory. But it reveals something important about how Australia’s mortgage market works — and why reviewing your home loan, particularly in a rising-rate environment, can make a meaningful financial difference.
The RBA Rate Hike Expected Today
All four major banks — ANZ, Commonwealth Bank, NAB, and Westpac — have forecast a 25-basis-point rate increase at today’s RBA board meeting, which would take the official cash rate to 4.35%. If passed on in full by lenders, this would add approximately $100 per month to repayments on a typical $600,000 variable-rate mortgage.
For context, the major banks have flagged challenging economic conditions ahead. NAB’s economists have outlined a downside scenario involving a potential recession in 2026–2027, while CBA has forecast inflation could climb as high as 5.4% before easing. Westpac has warned that households in Victoria and New South Wales are facing some of the tightest financial conditions seen since the early 1990s.
These are serious projections — and they underscore why it’s more important than ever for Australian borrowers to understand their loan, their rate, and their options.
So Why Is a Lender Cutting Rates Right Now?
The Australian home loan market is genuinely competitive — and this creates a dynamic that many borrowers aren’t aware of: the rate you’re currently paying may not be the rate the same lender is offering new customers today.
Non-major lender ING announced today that it is reducing variable interest rates on its Mortgage Simplifier product — a low-cost home loan with no ongoing fees and unlimited extra repayments — by up to 0.15% per annum for new owner-occupier and investor customers. The reductions apply to both principal-and-interest and interest-only repayment types, and vary depending on the borrower’s loan-to-value ratio (LVR).
This out-of-cycle rate move reflects a broader pattern: lenders compete aggressively for new business, particularly through the mortgage broker channel, even when the macro rate environment is tightening. Macquarie Bank, for instance, has grown its mortgage book by 27.1% over the past year — almost entirely through brokers — precisely because it has consistently offered competitive pricing to new customers.
The practical implication? Existing borrowers can sometimes end up paying more than new customers, even with the same lender.
The “Loyalty Tax” on Existing Borrowers
This phenomenon — sometimes called the “loyalty tax” or the “back-book premium” — is one of the most consistent features of the Australian mortgage market. Banks invest heavily in attracting new customers, but often do less to retain existing ones with competitive pricing.
During 2023 and 2024, some lenders were offering significant cash-back offers and sharp rate discounts to attract new business. Those headline offers have largely disappeared in 2026, but that doesn’t mean the gap between what banks charge their existing customers and what they’re willing to offer new ones has closed entirely.
If you haven’t reviewed your home loan in the past 12–18 months, it’s worth asking two questions:
- What rate am I currently paying?
- What is the same lender currently offering new customers on a comparable product?
If there’s a gap, you have options. You can negotiate with your existing lender for a rate reduction, or speak to a mortgage broker about whether refinancing makes financial sense given your circumstances.
What This Means for Borrowers Rolling Off Fixed Rates
For Australians whose fixed-rate mortgage terms are expiring in 2026, today’s environment presents a specific challenge. Not only will their repayments likely increase when moving to a variable rate, but if they want to refinance to another lender, they’ll need to pass a serviceability assessment that now reflects a higher cash rate plus the regulatory buffer.
This means some borrowers may find themselves unable to refinance — not because they’ve had financial difficulties, but because the mathematics of serviceability testing has shifted. A mortgage broker can help you understand whether refinancing is feasible, or whether negotiating a rate reduction with your existing lender is a more practical path.
What About Investors?
The APRA data released in recent weeks shows that investor lending is currently growing faster than owner-occupier lending — despite new debt-to-income (DTI) restrictions that came into effect in February 2026. This suggests property investors remain active in the market, but cost management is increasingly important.
With interest costs rising across the board, investors should review whether their current loan structure — particularly any interest-only arrangements — remains appropriate for their circumstances. Higher interest costs can affect rental yield calculations and overall portfolio strategy.
It’s important to note that any decision about investment property financing should be made in the context of your overall financial situation and in consultation with both a licensed mortgage broker and a financial adviser.
How a Mortgage Broker Can Help You Navigate This Environment
With 35+ lenders on FinHub’s panel and access to a wide range of loan products, a mortgage broker can help you compare your current rate against what the market is offering — and identify whether there’s a material saving available given your individual circumstances.
Importantly, a broker does this work on your behalf, dealing directly with lenders, handling paperwork, and explaining trade-offs in plain language. This is particularly valuable in a period when loan products, rates, and lender policies are changing rapidly.
FinHub’s brokers are award-finalist brokers with more than 350 five-star Google reviews and over $600 million in loans settled. They work with both owner-occupiers and investors, first home buyers and refinancers, across a wide range of lender options.
Key Considerations Before Refinancing
Before deciding to refinance, it’s worth understanding the full cost picture. Switching loans can involve:
- Discharge fees from your current lender
- Upfront costs at the new lender (application, valuation, legal fees)
- Break costs if you’re on a fixed rate
- LMI (Lenders Mortgage Insurance) if your LVR has changed
These costs need to be weighed against the potential savings. A broker can model this for you based on your actual loan balance, remaining term, and the rates and products available.
Refinancing is not always the right answer — but neither is staying on a rate you haven’t reviewed in years.
What Should You Do Right Now?
Given the rate environment, here are some practical steps borrowers can consider:
- Check your current interest rate on your latest mortgage statement or through your lender’s app.
- Compare that rate to what the same lender is currently advertising for new customers on a comparable product.
- Book a no-obligation conversation with a mortgage broker to understand whether your current loan remains competitive.
- Consider your fixed rate expiry date if you’re on a fixed term — planning ahead can help you avoid ending up on a default variable rate.
- Don’t assume loyalty is rewarded — the Australian mortgage market rewards those who review their loan, not those who set-and-forget.
Frequently Asked Questions
1. Why would a lender cut rates on the same day the RBA hikes?
Lenders set their own rates based on multiple factors, including their funding costs, competitive positioning, and strategic goals — not just the RBA cash rate. A lender may choose to cut rates for new customers to attract business through specific channels (like the broker market), even if the broader rate environment is rising. This is a normal feature of a competitive mortgage market.
2. Does the RBA rate hike automatically mean my variable rate goes up?
Not automatically — lenders decide independently whether and how much of a cash rate change to pass on to borrowers. Historically, most lenders do pass on rate increases (in full or partially), but this is not guaranteed. Your lender will notify you of any changes to your interest rate in advance. It’s worth checking your loan contract and keeping an eye on announcements from your lender.
3. How do I know if my home loan is still competitive?
The simplest starting point is to check what your current lender is offering new customers on a comparable product. If there’s a significant gap, that’s worth exploring. A mortgage broker can also compare your current rate across their panel of 35+ lenders to give you a broader picture. Your full financial situation would need to be reviewed before any recommendations could be made.
