Interest Rate Predictions Australia: Could Rates Lift Off Again Before Xmas?

Three of the big four banks have quietly changed their minds. Where the talk a few months ago was of holds and eventual cuts, several of the majors have now pivoted and are predicting rate hikes this side of Christmas.

The interest rate predictions Australian homeowners are seeing in the headlines are forecasts, not decisions. Rather than panic, use them as a cue to plan. 

Quick Answer: Will Rates Rise Before Christmas?

Probably. NAB expects a 0.25% rate rise in September, while Commonwealth Bank and ANZ expect the same move in November. Westpac is the outlier, forecasting a cut in September 2027. If the majority view plays out, the cash rate could reach 4.60% by year-end, adding around $91 a month to a $600,000 loan with 25 years remaining. 

None of that is settled. What is worth doing now is checking where your own rate sits against the market, because a competitive rate today cushions whatever the RBA does next. This is the exact conversation the team at Osinski Finance has been having with clients across Rockingham and greater Perth since 2017, and it usually ends with a number the borrower did not expect.

Where Things Stand After a Quiet Few Months

After three back-to-back rate hikes earlier this year, homeowners have enjoyed a welcome break from further rate rises. But the reprieve may be short-lived: three of Australia's four biggest home loan lenders have now sounded the alarm on possible hikes before Christmas.

Inflation Remains Higher Than Expected

What the RBA Has Committed To

The Reserve Bank of Australia (RBA) has made it clear that it is aiming for inflation of 2-3%, and only weeks ago signalled it will "do what it considers necessary" to bring inflation down. Central banks choose their words carefully, and an explicit commitment to act is usually the first signal that markets read.

Where the Numbers Actually Sit

The trouble is, inflation is proving remarkably stubborn. The latest CPI figures show that inflation in Australia is currently at 3.5%. While the rate has been gradually easing, it remains above the RBA’s preferred target range. The direction of travel is right, but the pace is not, and that gap is what has the major banks rethinking their rate expectations.

What Is Driving the RBA Rate Hike Forecasts

The big banks hold differing views on timing, but the common thread is that the next move may be up rather than down. The revised rate hike calls have come quickly, driven less by any single shock and more by the persistence of inflation. 

Rates Could Rise as Early as September

NAB is expecting a 0.25% rate increase in just a few weeks, when the RBA Board meets in late September. That is the earliest of the major forecasts and would give borrowers the least notice.

November Is the More Common Call

The Commonwealth Bank and ANZ Bank also expect a 0.25% lift, though not until November. Two of the four majors landing on the same month and the same size of move is a reasonably strong signal, even if it is not a guarantee.

Westpac Sees It Differently

Westpac alone expects the next move to be down, and not until September 2027. It is worth holding onto that dissent. Anyone asking when interest rates will go down in Australia should note that credible economists are reading the same data and reaching opposite conclusions.

The Forecasts Side by Side

In short, three of the four majors expect the same 0.25% increase and the same destination of 4.60%, differing only on whether it lands in late September or November. Westpac stands apart, forecasting a cut that takes the cash rate below 4.35%, but not before September 2027.

How a Rate Rise Could Impact Your Home Loan Repayments

If the majority are right, the RBA cash rate climbs from 4.35% to 4.6% by year's end. We have not seen it at that level since 2010, which puts the move into perspective for anyone who bought in the years since.

What It Costs in Dollars

A 0.25% hike could add around $91 to monthly repayments on a $600,000 loan with 25 years remaining, according to an analysis by Canstar. On an $800,000 loan, the increase is roughly $121 a month, and on a $1 million mortgage over the same term, around $152. Annualised, that is between $1,092 and $1,824 depending on the size of your loan.

Individually, those figures are manageable for most households. Stacked on top of the three increases already delivered this year, they are the reason mortgage stress keeps coming up in conversation. Running your own numbers through a mortgage repayment calculator before the decision lands takes the guesswork out of it.

The RBA Dates Worth Marking

The Board does not meet every month, so the window for any move is narrower than people assume. The published RBA meeting dates are the only calendar that matters, and the next RBA interest rate decision falls in late September. If that meeting passes without a change, attention shifts straight to November. You can also follow movements through our interest rate tracker between meetings.

What You Can Do Now to Prepare

No one can say with certainty whether we will see a pre-Christmas hike, but every step below is worth taking regardless of what the Board decides.

Check Your Current Rate First

Start with your current rate. It gives you a baseline to gauge whether you are paying more than necessary. Most borrowers we speak to have not looked in over a year, and a surprising number are on a figure their lender quietly stopped offering new customers months ago.

Compare It Against the Market

Today's average variable home loan rate is 6.65%, yet close to 50 lenders are currently offering variable home loan rates below 6%. Not all of those loans will suit every borrower, but the spread shows how competitive the mortgage market is and what is potentially available to you.

Stress Test Your Own Budget

Apply the dollar figures above to your actual loan balance, then consider whether the difference would come from your savings, reduce your spending, or have little to no impact on your budget. Households that find the answer uncomfortable have time to act now, which is a very different position from finding out after the fact.

Weigh Up Fixed Versus Variable

The fixed vs variable home loan question resurfaces every time a hike looks likely, and there is no single right answer. Fixing buys certainty and gives up flexibility, including the ability to benefit if Westpac turns out to be right. Some borrowers split the difference between the two. Our fixed rate home loan options in Perth page walks through what each structure actually locks in.

Have the Conversation Early

Lenders move quickly once a change is announced, and the review queue gets long. Getting your position assessed while the market is quiet means any switch can be underway rather than sitting in a backlog.

Why Wait for Possible Future Rate Hikes?

We can assess your options today to see whether you could save by refinancing to a new loan and lender, or help you negotiate with your current lender to see if they can match a better deal. Both paths are worth testing, and it costs nothing to find out which one applies to you.

What This Means for You

Forecasts change, and they have already changed once this year. What does not change is that a borrower on a sharp rate absorbs a 0.25% move far more comfortably than one who has drifted onto their lender's back book. Whether the Board lifts in September, waits until November, or holds through to 2027, the preparation is identical. The gap between now and the next meeting is the useful part.

Key Takeaways

• Three of Australia's four major banks now forecast a 0.25% cash rate increase before the end of 2026: NAB in late September, CommBank and ANZ in November.
• That would lift the RBA cash rate from 4.35% to 4.60%, a level Australia has not seen since 2010.
• The move would add roughly $91 a month to a $600,000 loan, $121 to an $800,000 loan and $152 to a $1 million loan, each on a 25-year term.
• Inflation at 3.5% remains above the RBA's 2-3% target band, which is the primary reason the majors revised their forecasts.
• Westpac is the sole major forecasting a cut, and not before September 2027, so the outlook is genuinely contested.
• With the average variable home loan rate at 6.65% and close to 50 lenders offering below 6%, checking your rate now is worthwhile whatever the Board decides.

Frequently Asked Questions

Will interest rates go up in Australia before Christmas 2026?

Three of the four major banks currently forecast that they will. NAB expects a 0.25% increase at the late September RBA meeting, while Commonwealth Bank and ANZ both expect the same increase in November. Westpac disagrees and expects a cut in September 2027. These are forecasts from bank economists, not decisions, and the Board makes its own call based on the data available at each meeting.

How high will interest rates go in Australia?

Based on current major bank forecasts, the cash rate is expected to reach 4.60% by the end of 2026. None of the big four is forecasting a move beyond that in the near term. Longer range projections vary widely and become less reliable the further out they go. The RBA has not published a target level, only a commitment to bring inflation back to the 2-3% band.

What is the RBA cash rate right now?

The cash rate is currently 4.35%. It reached that level after three consecutive increases earlier in 2026 and has been held steady since. The RBA publishes the current cash rate along with the full history of movements, which is the authoritative source if you want to check it yourself at any time.

When is the next RBA interest rate decision?

The next Board meeting falls in late September 2026. The Reserve Bank publishes its full schedule in advance, so you can see exactly when each decision is due for the rest of the year and into next. If September passes without a change, the next opportunity is the November meeting, where two of the four major bank forecasts currently sit.

How much will my repayments go up if rates rise 0.25%?

On a $600,000 loan with 25 years remaining, a 0.25% increase adds approximately $91 to monthly repayments. On an $800,000 loan, it is around $121 a month, and on a $1 million loan around $152. These figures assume a principal and interest loan and that your lender passes on the full increase. Your actual change depends on your balance, remaining term and your lender's response.

Should I fix my home loan now or stay variable?

There is no universally correct answer. It depends on how much certainty you want against how much flexibility you are willing to give up. Fixing locks in your repayment and protects you if the majority forecasts are right, but it means you do not benefit if rates fall and it usually limits extra repayments. Staying variable keeps your options open, including the ability to refinance without break costs. Many borrowers split their loan across both to hedge the outcome.

When will interest rates go down in Australia?

That depends entirely on inflation. Westpac, the only major currently forecasting cuts, does not expect them until September 2027. The other three expect an increase first, which would push any subsequent easing further out. The RBA has been explicit that it will act as needed to return inflation to its target band, so the timing of cuts follows the inflation data rather than any fixed schedule.

Does a cash rate rise always mean my home loan rate goes up?

Not automatically, and not always by the full amount. Lenders set their own variable rates and decide individually whether to pass on the entire increase, part of it, or delay it. In practice, most pass on the majority of a cash rate move to variable customers within a few weeks. If you are on a fixed rate, nothing changes until your fixed term ends.

Is it worth refinancing before a possible rate rise?

It can be, particularly if your current rate sits above the market average of 6.65%. Moving to a sharper rate before an increase means the higher rate is applied to a lower starting point, which reduces the dollar impact. The process takes time, so starting before an announcement usually means a smoother run. A broker can tell you quickly whether a switch stacks up once fees and features are accounted for.

Should I wait to see what the RBA does before reviewing my loan?

Waiting rarely helps. A review now gives you a baseline and, if a better rate is available, the chance to move before lenders are handling a surge of enquiries. If rates rise, you are already on a better footing. If they hold or fall, you have still improved your position. Either way the review costs nothing.
