How today's RBA rate hike affects your hip pocket

Rate rises are felt fastest, and most sharply, by Australians with variable-rate mortgages because banks typically pass on RBA increases in full.

AMP chief economist Shane Oliver says the cash rate is the main tool steering borrowing costs and households should expect lenders to adjust quickly.

"As we've seen with the first four hikes this year, the banks will likely announce a 0.25 per cent increase in their mortgage rates on the same day," Dr Oliver says.

Each 0.25 per cent rise in the cash rate adds roughly $92 per month to repayments on a $600,000 variable-rate loan with 25 years remaining. The five 2026 increases totalling 1 per cent have added approximately $456 per month for borrowers on a $600,000 loan.

That equates to around $5,472 extra per year.

Here's how much a November rate hike will cost borrowers:

It is not just existing mortgage borrowers hit by the rate rises though.

For prospective buyers, Canstar estimates the borrowing capacity of someone on an average full-time wage of $108,650 would be reduced by more than $58,000, while a couple, both on average wages, would see a reduction of nearly $117,000.

If you are on a fixed-rate home loan, you won't see any changes. Those rates are locked in.

But when the fixed term expires and rolls to a variable rate, the full impact of any rate cycle will apply at once.

For renters, the interest rate impact is more indirect.

Some landlords may try to offset the impact of rate rises on their cash flow by increasing rent. Although, there are constraints in how often and how much rent can be increased by each year in most states.

But the notion that landlords pass their increased borrowing costs onto renters has been challenged by the RBA.

Speaking on 9Now's The Pay Off podcast, RBA chief economist Sarah Hunter said what was really driving rent came down to supply and demand.

"If you're an individual landlord, you own one property in one rental market, you might want to put the rent up when your interest rate goes up if you've got a mortgage," Dr Hunter said.

"But you're competing with all the other properties that are available … and so, it's demand and supply, it's the local market that will equilibrate rent.

"If rents are tracking up, it's usually because demand growth is stronger than supply growth."

Cotality's quarterly rental review found rents rose by 0.5 per cent nationally in the September quarter, driven by a severe lack of available stock across the country.

The national dwelling vacancy rate sat at 2.1 per cent, unchanged from March and remains well below the pre-COVID decade average of 3.3 per cent.

Dr Mardiasmo says higher interest rates can still influence rents indirectly by affecting the number of investors entering the market.

"If investors are discouraged from entering the market because of reduced borrowing power and higher loan repayments, there may be fewer rental properties available," Dr Mardiasmo said.

"When demand for rental housing remains strong but supply falls, competition among tenants increases and that can put upward pressure on rents."

Higher interest rates tend to strengthen the Australian dollar (AUD).

And that's because it's more attractive for foreign investors to park their money in Australian interest-bearing assets (like savings accounts, term deposits, and government bonds) because they can get a higher rate of interest here.

This increases demand for the AUD, making the currency more valuable.

"Australians who are purchasing items overseas, are going on holidays, or have term deposits/savings overseas can benefit," Dr Mardiasmo says.

"For businesses who import goods, it also means that their import costs are now cheaper, which supports better profit."

But Commonwealth Bank head of Australian economics Belinda Allen says the Australian dollar's value depends on far more than the RBA's cash rate decisions.

"The Australian dollar is influenced by many things: global interest rates, commodity prices, China, investor sentiment and expectations about the Australian economy; so you can't say that a 25-basis-point rate hike will automatically result in a particular move in the dollar."

There is one silver lining: savings account and term deposit interest rates usually rise after an RBA hike, making it more attractive to park your money.

This is because, while the cash rate affects borrowing costs for banks, it also sets the rate of return for their own deposits. Cash rate hikes improve their returns, which may be passed on to consumers through higher savings interest rates.

Dr Oliver says while short-term deposit rates largely move in line with the cash rate, longer-term term deposit rates are also shaped by government bond yields and other borrowing costs.

With today's RBA increase and bond yields already rising, he says savers are likely to benefit from higher returns.

"The odds are, yes, we will see deposit rates continue to rise."

But as ABC business reporter Adelaide Miller reported, Australians with billions in savings could be missing out on the benefits of rising rates if they're in the wrong account or fail to meet bonus rate conditions.

Canstar found higher rates were often restricted to select products with strict requirements, with customers otherwise earning a base rate as low as 0.10 per cent.

Car loans and personal loans can be affected by increases in the cash rate.

But it all comes down to what type of loan you have.

Australians collectively borrowed about $4.7 billion in fixed-term personal loans for road vehicles in the three months to June 2026, according to the Australian Bureau of Statistics.

These loans would not be affected by the cash rate until the fixed-rate period ended.

For those on a variable rate however, Dr Oliver says banks may not necessarily hike rates by the full 0.25 per cent, but "the odds are they'll probably go up over time as well".

Dr Mardiasmo says it also depends on who you have a car loan with: bank, car dealer, or the manufacturer themselves, and how each of those are structured.
