RBA Rate Rise Expected Tomorrow: A Detailed Mortgage Broker Guide to What Borrowers Should Do Now

Why is another rate rise being discussed?

The September increase to 4.60% was driven by the RBA’s concern that inflation remained too high and that several upside risks were becoming more persistent. The Bank pointed to stronger-than-expected inflation, domestic capacity pressures, elevated short-term inflation expectations, higher energy costs and firms reporting broader cost pressures.

The important point is that the RBA is not reacting to one isolated number. It is trying to judge whether inflation is becoming embedded enough that higher interest rates are needed for longer.

How a cash-rate rise reaches your mortgage

The RBA cash rate is not your mortgage rate. But it influences lenders’ funding costs and broader market pricing. After an RBA increase, lenders decide whether to change their variable rates, by how much and from what date.

This means a 0.25% RBA move does not guarantee your own rate rises by exactly 0.25%. However, borrowers should prepare for the possibility of a full pass-through rather than assuming lenders will absorb the increase.

Repayment impact: what another 0.25% could look like

To show the scale of the change, the table below models a 30-year principal-and-interest mortgage at 6.25%, 6.50% and 6.75%.

Illustrative only. Actual repayments depend on remaining term, rate, lender method, fees, repayment frequency and product structure.

The bigger issue: borrowing capacity can fall too

Borrowers often focus on repayments, but a rate rise also matters for serviceability. APRA’s mortgage serviceability buffer remains at 3 percentage points. In simple terms, lenders generally assess borrowers at a rate materially above the actual loan rate.

If the actual mortgage rate rises, the assessment rate used for new borrowing or refinancing can also move higher. That can reduce maximum borrowing capacity even if your income has not changed.

Why refinancing can become harder at the same time you need it most

Higher rates create a difficult dynamic. Borrowers may want to refinance because their repayments are rising, but the new lender still needs to assess their income, expenses, liabilities and serviceability.

If a household is already close to its borrowing limit, higher assessment rates can reduce the amount a new lender is willing to approve. This is why it can be better to review the mortgage before cash flow becomes severely stretched.

Do not judge a refinance only by the advertised rate

• Compare the same remaining loan term first.
• Include discharge, registration and establishment costs.
• Check annual or package fees.
• Consider whether the new loan has a useful offset or redraw feature.
• Include any fixed-rate break cost.
• Compare total interest, not only monthly repayment.
• Check whether the lower rate is introductory or ongoing.

Why resetting the loan to 30 years can be misleading

Suppose you have 20 years remaining and refinance into a fresh 30-year loan. The repayment may fall sharply because the principal is now spread over another decade. That can look like a major saving even if the interest rate improvement is relatively small.

The lower repayment may help cash flow, but the longer term can materially increase total interest. A fair comparison should first use the same remaining term, then separately test whether extending the term is worth the trade-off.

Offset accounts become more valuable when rates rise

For borrowers with a genuine 100% offset account, higher mortgage rates increase the interest-saving value of money held in the offset. If you have a $500,000 mortgage and maintain $50,000 in offset, interest may effectively be calculated on around $450,000 instead of the full balance, subject to the product terms.

That does not mean every spare dollar should be moved purely to reduce interest. Maintaining accessible emergency funds is still important, and some loans charge higher rates or fees for offset features.

What fixed-rate borrowers should prepare for

Existing fixed-rate borrowers are generally insulated from tomorrow’s decision until their fixed period ends. The risk comes at rollover.

A borrower moving from an older low fixed rate to a much higher variable or new fixed rate can experience a much larger repayment jump than the 0.25% headline suggests. If your fixed period expires within six to twelve months, reviewing your options early can give you more time to compare products and budget for the change.

What first home buyers should do now

For first home buyers, the decision affects more than mortgage repayments. Higher rates can reduce borrowing power and change the maximum property price you can realistically target.

• Update your borrowing-capacity estimate.
• Do not rely on an old pre-approval.
• Recheck your deposit and upfront purchasing costs.
• Maintain a post-settlement cash buffer.
• Avoid unnecessary new credit before applying.
• Stress-test the loan at a higher rate before signing a contract.

What property investors should analyse

Investors should review whether higher interest costs materially change property cash flow. A property that was mildly negatively geared can become substantially more cash-flow negative when rates rise.

Review rental income, property expenses, interest costs, cash reserves and whether the loan structure remains suitable. Tax consequences should be discussed with a qualified tax adviser rather than assumed from mortgage calculations alone.

What happens to the property market?

Higher rates generally reduce borrowing capacity and buyer confidence, which can weaken demand. Recent housing data already show softer conditions across major markets, with falling prices and lower transaction volumes.

However, property-market outcomes are highly local. A national rate rise does not mean every suburb falls by the same amount, and supply constraints, population growth and local employment can produce very different results.

For buyers, softer conditions can create negotiating opportunities. For sellers and investors, it may mean longer selling periods or more price sensitivity. For existing homeowners, the most important issue is often not the short-term valuation movement but whether the mortgage remains manageable.

When should you speak to a mortgage broker?

You do not need to wait until repayments become uncomfortable. A broker review can be useful if your rate has not been reviewed recently, your fixed period is ending, you are considering refinancing, your borrowing capacity has changed, or you simply want to understand what another rate rise means for your budget.

The purpose is not to predict the RBA perfectly. It is to understand your exposure and compare realistic options before you are forced to make a rushed decision.

What happens tomorrow?

The RBA’s Monetary Policy Board decision is due at 2:30 pm AEDT on Tuesday, 3 November 2026. The Statement on Monetary Policy is scheduled for release at the same time, with the media conference at 3:30 pm AEDT.

The cash rate remains 4.60% tonight. Financial markets are pricing close to a 90% probability of a 0.25 percentage point increase to 4.85%, but the decision is not official until the RBA announces it.
