Central banks have moved in different directions during September, but the broader pattern is clear: inflation concerns are keeping interest rates higher for longer.
The United States, New Zealand and the euro area increased their policy rates this month. Japan also announced an increase, while the United Kingdom and Canada left rates unchanged.
Australia’s cash rate remains at 4.35%, with the Reserve Bank of Australia’s next decision due on 29 September.

What does this mean for Australian borrowers?
International rate decisions provide useful context, but Australian mortgage rates are driven more directly by the RBA cash rate, wholesale funding costs, competition between lenders and individual lender pricing decisions.
For borrowers, the immediate event to watch is the RBA’s September meeting. However, you do not need to predict the next decision before reviewing your loan.
A loan review should consider:
- Your current interest rate compared with available alternatives
- Annual package fees and other ongoing costs
- Offset and redraw features
- Fixed-rate break costs
- Restrictions on additional repayments
- Your expected loan term
- Whether your financial position or property value has changed
- The total cost of refinancing, not only the advertised rate
Should you fix your home loan?
A fixed rate can provide repayment certainty, but it may also limit flexibility.
Before fixing, consider the fixed period, available offset arrangements, additional repayment limits and potential break costs. You should also consider what happens when the fixed period expires.
The lowest advertised rate is not automatically the most suitable option. Loan structure, flexibility and your expected property plans matter.
Is it worth refinancing?
Refinancing may be worthwhile if it produces a meaningful financial or structural improvement after costs.
The assessment should include the new interest rate, fees, cashback conditions, valuation, loan features and how long you expect to retain the loan. Extending the loan term may reduce the required monthly repayment, but it can increase total interest if the debt is repaid more slowly.
My view
Interest-rate decisions matter, but borrowers should avoid building their entire lending strategy around one central bank announcement.
Your loan structure should reflect your cash flow, financial buffers, repayment plans and need for flexibility.
If your loan has not been reviewed recently, assessing your current pricing and structure may identify opportunities without relying on a forecast about what the RBA will do next.
