RBA Decision Day: What It Means for Your Home Loan Pre-Approval and Borrowing Power

Summary:

Today’s RBA decision changes less than it feels like it does if you already have a plan, and more than you’d expect if you don’t.

• A rate move never cancels a pre-approval you already hold. It only applies to a new application submitted after the rate changes or after your approval expires.

• Lenders test your borrowing power against a buffer sitting above the actual rate. That buffer, not the headline number, decides how a decision like this reshapes what you can borrow.

• Your current lender isn’t obliged to offer you its best deal. Many only respond once you’ve started the process to leave, which is why Fox Home Loans contacts your lender directly on your behalf.

• Fixed rates moved before today’s decision regardless of the outcome. Eighteen lenders repriced fixed home loans in September 2026 alone.

• Falling property values can work in a ready buyer’s favour. A lower price usually means a smaller deposit stretches further and can reduce or remove lenders mortgage insurance.

The Reserve Bank of Australia (RBA) raised the cash rate again today, the fourth increase in 2026, taking it to 4.60%. Here’s what that actually changes: your borrowing power, your existing pre-approval, and your options if your current lender isn’t offering you the sharpest deal on the table. Maybe you already hold a home loan pre-approval. Maybe you’re just weighing up whether now is still a good time to buy. Either way, the number itself matters less than what you do next.

What Today’s RBA Decision Actually Changes (and Doesn’t)

A 25 basis point rise moves the cash rate to 4.60%, the fourth hike of 2026. It doesn’t automatically cancel a pre-approval you already hold. Lenders honour a pre-approval granted before a rate change. What it does mean is simple: any new application, or one submitted after your pre-approval expires, gets assessed against the new rate.

Some lenders let you split your loan and fix part of it if a move like today’s worries you. Only that portion of your repayment is then exposed to further rises. A handful also offer a rate lock at the point you apply, for an extra fee, if you’re worried about missing out before your loan settles. It’s worth asking your broker whether either option genuinely suits your situation before you commit to anything.

It covers the same question from the previous hold cycle. It’s still relevant if your situation is closer to “should I bother reviewing this at all” than a borrowing-power question.

How Does a Rate Decision Change How Much You Can Borrow?

Your borrowing capacity isn’t set by the advertised rate alone. Lenders test your ability to repay at a buffer above the actual rate. That buffer, not the headline number, decides how much you can borrow. When rates move, the buffer moves with them, and a rate decision can change what a lender is willing to lend you by tens of thousands of dollars.

Every lender applies a serviceability buffer on top of the actual interest rate. It exists so a change in rates, or in your own circumstances, doesn’t tip you into financial hardship. The exact figure varies from one lender to the next. That’s why two people on the same income can be offered very different borrowing limits at different banks.

We regularly see the same pattern. Someone waits until money feels tight before asking about pre-approval, rather than while their situation is stable, and ends up facing a harder conversation. Regularly dipping into an offset account or a credit facility can raise a question for a lender: how would a new repayment actually be managed? Acting while your finances are steady, rather than waiting, can be the difference of one to three percent in the rate and terms a lender offers.

Should You Ask a Lender to Compete for Your Business?

You can call your current lender and ask them to match a better deal. There’s no guarantee they’ll offer one, though, and many won’t act until you’ve formally started the process to leave. Fox Home Loans can make that call directly on your behalf. Part of our service is contacting your current lender to negotiate a reprice, while you keep every option open.

We regularly find a customer a materially better deal elsewhere. We then watch a lender suddenly become responsive once we request a discharge authority, after months of ignoring a direct request to reprice. A bank advertising a lower new-to-bank rate doesn’t mean it will offer you that same rate as an existing customer. That gap, between the advertised rate and what you’re actually paying, is exactly what a reprice conversation, or a full refinance, closes.

A full refinance might turn out to be the better move once we’ve run the numbers. If so, our home loan health check (https://www.foxhomeloans.com.au/home-loans/health-check/) is the place to start. It compares what you’re on now against what’s actually available, without committing you to anything.

Fixed-Rate Pricing Already Moved Before the Decision, What That Means

Fixed home loan rates don’t wait for the RBA. Lenders price them off their own wholesale funding costs.

In September 2026, eighteen lenders lifted fixed home loan rates ahead of today’s decision.

Macquarie raised its fixed rates twice within three weeks (brokernews.com.au).

That repricing already happened. Today’s decision doesn’t undo it, or confirm it, either way.

If you’re still weeks from settlement and worried about a fixed rate moving again before then, ask about a rate lock. Some lenders let you hold a rate for an extra fee at the point you apply, which protects you from further movement before you settle. It’s the same mechanism mentioned above for variable borrowers weighing up a split loan, just applied to the fixed side.

Buying? A Softer Market Can Be a Buyer’s Market

National dwelling values fell 0.9% in August 2026. It’s the fifth consecutive monthly decline, and values are now 3.6% below their March 2026 peak. The national median sits at $912,885. 93% of capital-city suburbs recorded a fall through winter, up from 45.8% in autumn. That’s according to the Cotality Home Value Index.

Falling prices aren’t only a warning sign. For a buyer with finance ready to go, they can be the opening.

A lower purchase price does more than one thing at once. It usually means a smaller deposit stretches further, a lower or even no lenders mortgage insurance bill, less stamp duty, and a smaller repayment from day one. Timing a falling market perfectly is close to impossible, too. By the time enough people agree prices have hit bottom, everyone is back in the market at once, and the advantage is gone.

Valuation is its own separate conversation once you’re this close to a decision. Different valuation methods can vary by ten to twenty percent on the same property. That’s part of why having a broker who will push back on a low valuation, rather than simply accept the first number, matters.

Whichever way today’s decision landed, the honest answer is the same. Get your numbers checked against where things actually stand today, not where they stood at your last application. We handle the heavy lifting on that review. That might mean confirming your existing pre-approval still fits, running a fresh borrowing power check, or contacting your current lender on your behalf to ask for a better deal.

Give our friendly team a call, or start your application online in about five minutes. No obligation, and checking your numbers again won’t affect your credit score. Fox Home Loans is your trusted mortgage broker on the Sunshine Coast.
