What Another Rate Hike Really Means for Your Wallet

The Reserve Bank has lifted the cash rate again, and if you're feeling like you've been here before, you're right. This is the fourth increase this year. As a mortgage broker, my phone tends to light up on days like this, so I want to get ahead of the questions I know are coming: what does it cost me, what does it mean if I'm buying, and is there anything good in it for me?

Here's my plain-English rundown of who feels a rate rise, how much, and what you can do about it.

If you have a variable-rate mortgage

Variable-rate borrowers feel it first and feel it most. Lenders have a habit of passing RBA increases on in full, and quickly. AMP chief economist Shane Oliver points out that after the first three hikes this year, the big banks moved on the same day as the RBA. There's no reason to expect this one will be any different.

So what does that look like in dollars? On a $600,000 variable loan with 25 years left to run, every 0.25 per cent rise adds roughly $91 a month to your repayments. Stack up this year's four rises and you're looking at about $360 more each month, or around $4,320 a year.

Rate rises (0.25% each)	Extra per month	Extra per year
1 rise	about $91	about $1,090
4 rises (2026 so far)	about $360	about $4,320

Figures are approximate and based on a $600,000 variable-rate loan with 25 years remaining.

Economists call this the cash flow channel. In everyday terms, when the mortgage takes a bigger bite, households cut back on spending or dip into savings to keep up. That's exactly how the RBA hopes rate rises will cool demand in the economy, and it's why the effect lands so squarely on mortgage holders.

Broker tip: if your loan hasn't been reviewed in a while, now is a good time. Many lenders reserve their sharpest rates for new customers, and a quick comparison (or a refinance) can claw back part of what the increases have cost you. That's a conversation I'm always happy to have.

If you're on a fixed rate

You're safe for now. Your rate is locked in, so today's decision changes nothing about your repayments until the fixed term ends.

The catch is what happens next. When your fixed period expires and the loan reverts to a variable rate, you'll wear the full effect of every rise since you fixed, all at once. If your term is ending in the next 6 to 12 months, start planning early. Look at your refinance options, compare new fixed rates, and don't just let the loan roll over by default.

If you're hoping to buy

Rate rises don't only hurt existing borrowers. They also shrink what the banks will lend you. Canstar estimates that someone earning the average full-time wage of $108,650 has seen their borrowing capacity fall by more than $47,000. For a couple who both earn average wages, the drop is close to $95,000.

That can change the whole shape of a home search: the suburbs you can consider, the size of property you can afford, and how big a deposit you'll need. Before you go house hunting, get a fresh pre-approval based on today's rates, not the ones from six months ago.

If you're renting

For renters the link is far less direct, and it's a myth that every rate rise automatically means higher rent. Some landlords with a mortgage may want to push rents up to cover their costs, and there are limits in most states on how often and by how much they can do it.

More importantly, the RBA doesn't accept that landlords simply pass on their higher borrowing costs. RBA chief economist Sarah Hunter has explained that rents are set by the local market. A landlord competes with every other available property, so what actually moves rents is supply and demand. Dr Oliver and other economists agree.

And right now, supply is the problem. Cotality's latest quarterly review found national rents rose 1.6 per cent in the June quarter, driven by a severe shortage of available homes. The national vacancy rate is sitting at 1.6 per cent, below the five-year average of 1.8 per cent.

If you're a saver

Here's the silver lining. When the RBA lifts the cash rate, savings accounts and term deposits usually follow. The cash rate sets the return banks earn on their own deposits, and some of that improved return tends to flow through to customers.

Dr Oliver notes that short-term deposit rates generally move in line with the cash rate, while longer-term deposits are also influenced by government bond yields. With bond yields already climbing, he expects deposit rates to keep rising. If your savings are sitting in a low-interest account, it's worth shopping around.

Broker tip: if you have cash in a savings account and a variable mortgage, check whether an offset account could work harder for you. Every dollar sitting in offset reduces the interest you pay on your loan.

What about the Australian dollar?

Higher interest rates tend to lift the Aussie dollar, because foreign investors are drawn to the better returns on Australian savings, term deposits and government bonds. More demand for AUD pushes its value up, which can make imports cheaper and overseas travel less expensive.

But it's not a sure thing. RBA-watchers stress that the currency reacts to plenty besides our cash rate, including global interest rates, commodity prices, China and investor sentiment. With the US Federal Reserve also tightening, Dr Oliver expects the dollar to stay roughly where it is.

Car loans and personal loans

Whether a rate rise touches your personal or car loan depends entirely on what type of loan you have. Fixed-rate loans won't change until the fixed period ends. That matters, because Australians borrowed about $4.7 billion in fixed-term personal loans for vehicles in the three months to June 2026, according to the ABS.

If yours is variable, expect it to head higher. Lenders may not pass on the full 0.25 per cent every time, but the likely direction is up.

The bottom line

•        Variable mortgage: expect repayments to rise, and consider a rate review or refinance.

•        Fixed mortgage: no change today, but plan ahead for when your term ends.

•        Buying: your borrowing power is lower, so get a fresh pre-approval.

•        Renting: supply and demand drive rents far more than interest rates.

•        Saving: higher deposit rates are likely, so make your money work harder.

Every household's situation is different, and there's no one-size-fits-all answer to a rate rise. If you'd like to know exactly where you stand, whether that's your current repayments, your refinance options or how much you could borrow, get in touch and we'll work through the numbers together.
