Interest Rates in 2026: What Borrowers Should Know

Interest rates move in cycles, and even small changes can have a real impact on cash flow, borrowing power and long-term interest costs. This article is designed to give borrowers a clear, practical framework for what to review — without relying on predictions or specific rate figures.

1) Understand what actually changes

When the market talks about interest rates, there are a few different layers: the RBA cash rate, lenders' variable rates, and fixed rates (which are often influenced by wholesale funding costs and expectations). Your loan rate may move differently depending on your lender, product and discount.

2) Do a rate and structure review (not just a rate check)

A good mortgage review looks at more than the headline rate. It checks whether your loan structure still fits your life: offset accounts, redraw access, split loans, fixed vs variable mix, and whether your repayments are aligned to your goals (pay down faster vs maximise flexibility).

3) If you are considering refinancing, compare the total outcome

Refinancing can reduce repayments or total interest — but it can also introduce costs (discharge fees, application fees, valuation fees) and trade-offs (different features, different servicing rules). The right question is: “What is the total benefit over 12–24 months and beyond?”

4) What to do with any repayment relief

If your repayments drop, consider keeping your repayment amount the same and directing the difference into your offset (or extra repayments, where appropriate). This can shorten the loan term and reduce total interest — while still keeping funds accessible.

5) Investors: revisit cash flow, buffers and risk

For investors, rate changes can influence borrowing capacity and cash flow. A smart review looks at buffers (offset balances), upcoming lease renewals, insurance coverage, and whether your portfolio is structured to stay resilient if conditions change.

A simple next step

If you have not reviewed your mortgage in the last 6–12 months, it is worth doing a quick check-in. A broker can compare your current deal against what is available, and also confirm your structure is set up for your next move (upgrade, refinance, purchase, or invest).
