RBA interest rates: Reserve Bank hikes cash rate for fifth time this year in blow to mortgage holders

The Reserve Bank of Australia raised the cash rate from 4.6% to 4.85%. This was the fifth increase this year. The decision aimed to regain control of inflation, which had reached 4.3% in the year to September. The cash rate is now at its highest level since 2008.

The monetary policy board was split. Six members supported the increase, while three preferred to keep rates unchanged. The RBA said it would continue doing what it considered necessary to return inflation sustainably to its target. However, it did not explicitly signal another increase.

That omission suggests the bank may now wait to assess the effects of this year’s five rises. Its forecasts still showed inflation rising through the final months of 2026, with growth weakening and unemployment climbing. The decision will increase pressure on mortgage holders and the federal government.

The RBA cash rate is the central bank’s key interest rate for monetary policy. It influences the cost of money in Australia and helps the RBA manage inflation. When the RBA changes it, banks commonly adjust the interest rates charged on variable-rate mortgages and other loans.

For a borrower, a higher mortgage rate means more interest is charged on the outstanding loan balance. For example, Canstar calculated that the latest increase would add $107 to the monthly interest payment on a $700,000 home loan. The change affects household budgets directly, especially when repayments are already high.

The RBA uses this mechanism to slow spending and demand. Higher repayments leave households with less money for other purchases. The article says the latest rise will affect more than 3.3 million households with home loans, while the bank waits to see how earlier increases affect inflation.

Canstar estimated that the latest rate rise will increase the monthly interest payment on a $700,000 home loan by $107. That is the immediate cost of moving the cash rate from 4.6% to 4.85%. The rise adds to the financial pressure already facing mortgage holders.

Across all five rate increases this year, repayments on the same loan have risen by $532 a month. The mechanism is straightforward: when lending rates rise, more of each repayment goes toward interest. Less money remains available for household spending, saving, or other bills.

The article says over 3.3 million Australian households have home loans. Those borrowers will feel the combined effect of higher repayments and the wider cost-of-living crisis. The RBA expects inflation to remain elevated, so mortgage pressure may continue while the central bank assesses whether its rate increases are working.

Higher interest rates can bring inflation down by slowing spending across the economy. When loans become more expensive, households may reduce purchases, while businesses may delay investment. Weaker demand can make it harder for companies to keep raising prices.

Mortgage repayments show the mechanism clearly. A $700,000 borrower faces an extra $107 in monthly interest after the latest increase. Across five rises, the increase reaches $532 a month. That money is no longer available for other goods and services, reducing demand in parts of the economy.

This tool cannot quickly remove every source of inflation. The article links Australia’s high inflation partly to an overseas oil shock, and says risks remain tilted upward. The RBA forecasts inflation will rise through late 2026 and return below 3% only by the end of next year, while growth remains weak.

Oil is traded globally, so a conflict overseas can affect Australian prices even when the disruption occurs elsewhere. The article links the global oil shock to the worsening conflict in the Middle East. Higher global oil prices raise fuel costs and can increase expenses for businesses across the economy.

Motorists pay more at the pump when fuel costs rise. Businesses also face higher costs for transport and other activities that depend on energy. Companies may pass some of those costs to customers, adding to inflation. The article says this pressure is making a quick return to lower inflation less likely.

The RBA forecasts that global oil prices will ease over the next 18 months, but remain relatively elevated. That means limited relief for motorists and continued high costs for businesses. It also explains why the bank views inflation risks as still skewed to the upside.

Raising interest rates while inflation remains high creates a difficult trade-off. Higher rates can reduce spending and price pressure, but they also make mortgages and business borrowing more expensive. That can weaken economic activity and create financial stress for households.

The article gives a direct example: repayments on a $700,000 home loan rise by $107 a month after the latest increase. Across five rises, they are up $532 monthly. The RBA also forecasts below-trend growth, with the economy expanding 1.6% this year and 1.3% in 2027.

Employment is expected to remain positive, but unemployment is forecast to rise from 4.7% now to about 4.9% next year and above 5% in 2028. The housing downturn is described as one of the steepest in 50 years, although the RBA sees no evidence of recession over the next two years.

Inflation is a sustained rise in the prices of goods and services. When inflation is high, household incomes may not keep pace with living costs, reducing purchasing power. The article reports inflation of 4.3% in the year to September, well above the RBA’s 2–3% target range.

The RBA uses interest rates to influence demand and bring price growth back toward that range. Higher rates raise borrowing costs and can reduce household spending and business investment. The aim is not to make prices fall generally, but to slow their increases to a more manageable pace.

The bank’s latest forecasts show how difficult that task is. Inflation is expected to rise through the final months of 2026 and return below 3% only by the end of next year. Meanwhile, weak growth, higher unemployment, elevated oil prices, and mortgage pressure create wider economic costs.
