The Reserve Bank of Australia is expected to increase the cash rate to 4.6% on Tuesday, marking its highest level since 2011 and leading to a rise in typical home loan interest rates to 6.5%. This hike would add approximately $119 to monthly mortgage repayments for someone with an average-sized new mortgage of $731,000. The article highlights the strain on household budgets due to increased mortgage costs and higher petrol prices, as well as the potential impact on consumer spending and house prices.

Story summary
The Reserve Bank of Australia (RBA) has raised interest rates to their highest level in 15 years, increasing the cash rate target from 4.35% to 4.60%. This is the fourth increase this year and reflects the RBA's ongoing efforts to combat high inflation.
On a $700,000 loan with a 25-year term at an interest rate of 6.50%, monthly mortgage repayments will increase by approximately $93 following the latest rise. Over four increases this year, borrowers would see their monthly payments increase by about $364 on a $600,000 loan and roughly $7,300 annually.
The impact extends beyond mortgages: higher interest rates attract foreign investment to Australia due to better returns, potentially strengthening the Australian dollar. However, increased borrowing costs will likely slow down spending in other sectors such as dining out and retail shopping, which could affect businesses reliant on consumer spending.
Despite the hikes, housing remains unaffordable for many, with further rate increases forecasted by some analysts up to 5.1% by mid-2027, posing significant challenges for household finances already strained by rising costs like petrol prices nearing $2.40 per liter. The Bureau of Statistics is set to release September's inflation data soon, which will provide more insight into the effectiveness of these measures and future policy directions.
