Rates at a 15-Year High, and Possibly Higher: What It Means for Your Mortgage, Your Portfolio and Your Next Move

The Reserve Bank’s Monetary Policy Board delivers its next interest rate decision on Tuesday 3 November, and this time the outcome looks less finely balanced. The cash rate currently sits at 4.60%, its highest level in almost 15 years, after four increases this year. Last week’s inflation data has pushed all four major banks to forecast a fifth rise, to 4.85%.

If the last few weeks of headlines have left you wondering what any of this means for you, you’re not alone. The honest answer is that it depends on where you sit. A rate rise that squeezes one household can help another. That’s worth working through properly instead of reacting to the news cycle.

Why a fifth rise is on the table
The latest inflation data, released on 28 October, came in firmer than expected. Monthly CPI rose to 4.3% over the year to September, up from 4.0% in August. The RBA’s preferred measure of underlying inflation, the trimmed mean, was 3.7% over the year to the September quarter, remaining above the RBA’s 2–3% target range. The lift was enough to move the banks: CBA and NAB had both expected the RBA to hold this month and now expect a hike. Market pricing for a November rise jumped from around 60% to around 90% on the day the data was released.

The picture beyond November is more mixed. CBA, for one, expects the RBA to hold in December and February, with cuts possible in the second half of 2027, though it stresses that timing is highly uncertain. Another rise isn’t a certainty, and a long run of rises isn’t the base case either.

What higher rates mean for repayments
As a rough guide, every 0.25% rise adds around $83 a month to repayments on a $500,000 loan, $99 on a $600,000 loan and $124 on a $750,000 loan (30-year principal-and-interest loans). Add up the year’s increases and the monthly cost has risen by hundreds of dollars for many households. The big four’s standard variable rates now sit between about 6.24% and 6.50% following the 9 October increases.

The housing market is already softening
National home values have now fallen for six consecutive months, 5.2% below the March peak, including a 3.7% fall in the September quarter alone. The pain is uneven. Sydney is down around 8.6% from its February peak, while Perth and Brisbane remain higher than a year ago despite recent falls. Cotality’s research director has said further falls into 2027 are likely, with a 10–15% peak-to-trough decline a “fairly reasonable estimate”. One well-known economist has said rates may be close to peaking but that the risk of one more hike remains high.

There’s a flip side that tends to get less airtime. Rental growth has slowed to its weakest quarterly pace in nearly two years, vacancy rates have lifted from 1.5% to 2.0% since February, and gross rental yields are at their highest level since 2019. The RBA’s latest Financial Stability Review also judged most mortgage holders well placed to cope, even if prices fell sharply, while acknowledging pockets of stress.

So this is not a crisis. But it isn’t nothing either. Here’s how it plays out depending on your situation.

If you’re a mortgage holder
Higher repayments, with the possibility of another rise, mean it’s worth looking at your numbers now, before the next increase lands. That might mean reviewing your loan structure and rate, making sure your offset account is working as hard as it can, and stress-testing your budget against another 0.25–0.50%. If your fixed rate is due to expire soon, start planning the move early. Don’t wait for the revert rate to arrive.

If you’re an investor or hold significant assets
Higher rates reshape the maths on several fronts at once. Geared property looks different with softer prices and higher borrowing costs, though stronger yields help the cash-flow side. Cash and fixed-income assets are paying more than they have in over a decade. Volatility is also back: the RBA itself has flagged global bond markets as a key risk. A calm, deliberate portfolio review beats a reactive one.

If you’re nearing or in retirement
This cycle has quietly worked in your favour if your portfolio leans towards income and capital stability. Deposit and fixed-income returns are the best in years. The more useful question isn’t whether rates are up, but whether your current mix still funds the retirement you want, including how it would perform if rates begin to fall again.

If you’re trying to buy your first home, or helping your kids do so
Borrowing capacity has been squeezed just as prices are falling, which can feel like two steps forward and two back. But falling prices, slower rental growth and a quieter market can also open a window for buyers who aren’t stretched to the limit. Whether this is the time to move or to wait depends on your numbers, not on the headline.

The bottom line
Very few people need to make a dramatic decision because of a rate announcement. What’s useful is knowing how this particular change, and the possibility of one more, sits against your plan: your mortgage, your portfolio, your timeline to retirement or your next property move.

That’s the conversation we’d rather have with you now, proactively, than after another round of headlines.
