The Reserve Bank of Australia (RBA) has raised the official cash rate by 0.25 percentage points to 4.85 per cent, marking its fifth interest rate increase in 2026 and taking borrowing costs to their highest level in 18 years.

The decision was announced on Tuesday, 3 November 2026, following the Reserve Bank's monetary policy meeting. The increase is expected to affect households, businesses and borrowers across the country.

For homeowners with variable-rate mortgages, the decision could mean higher monthly repayments if their lenders pass on the full increase. People with fixed-rate loans will generally not experience an immediate change, although their repayments may be affected when their fixed-rate periods end.

The rate increase also creates additional pressure for Australians who are already managing rising household expenses, including groceries, electricity, transport and housing costs.

Small businesses may also face higher financing expenses. Companies that depend on loans to purchase equipment, expand operations or manage cash flow could find borrowing more expensive.

The Reserve Bank uses interest rates as a tool to manage inflation and influence economic activity. Increasing the cash rate generally makes borrowing more expensive and encourages households and businesses to reduce spending. This can help ease demand and, over time, reduce inflationary pressure.

However, higher rates can also slow economic growth. Households may have less money available for discretionary spending, while businesses could reconsider investment and expansion plans.

The November decision followed concerns about persistent inflationary pressure. The RBA's announcement reflects its assessment that monetary policy needs to remain restrictive to bring inflation under control.

Financial markets and economists had been closely watching the meeting, with expectations of another increase building before the announcement.

Borrowers are being encouraged to review their household budgets and contact their lenders to understand how the rate change could affect their repayments. Comparing loan products and discussing repayment options may also help households manage the additional costs.

The full impact will depend on how individual banks respond and how quickly the higher rate is passed on to customers.

The decision is an important development for Australia's economy as households, businesses and financial markets adjust to another increase in borrowing costs.
