The Reserve Bank of Australia (RBA) lifted the cash rate by 0.25 percentage points on Tuesday, the fourth hike of 2026, taking the official rate to 4.6 per cent in an effort to control inflation that has persisted above the target band for most of the past six years.
For mortgage holders, the impact is immediate. Each 0.25 per cent rise adds roughly $91 per month to repayments on a $600,000 variable-rate loan with 25 years remaining. The four increases this year, totalling 0.75 percentage points, have added approximately $360 per month for such borrowers, or $4,320 extra per year.
Commonwealth Bank head of Australian economics Belinda Allen said the central bank had lost patience with inflation. "Higher interest rates make borrowing more expensive and saving more attractive," she said. "That tends to slow household spending and business investment."
AMP chief economist Shane Oliver noted that banks typically pass on RBA increases in full on the same day.
In response to the higher rate environment, financial experts are advising borrowers to consider switching lenders. The lowest home loan rates are now close to 6 per cent, and mortgage holders may be able to save hundreds of dollars a month by moving to a better deal. However, professionals warn that large discounts are increasingly hard to secure, and borrowers may need to be prepared to walk away from their current bank to get a competitive offer.
The RBA's decision also affects renters, as higher borrowing costs for landlords may be passed on through increased rents, and savers, who may benefit from better deposit rates as banks compete for funds.
