The timing matters. The RBA’s cash rate is currently 4.35%, after three increases earlier in 2026 and a hold at the June meeting. While fixed rates do not move in lockstep with the cash rate, they often reflect how lenders are pricing future funding costs and competitive pressure. In this case, NAB is not acting alone. A growing number of lenders have reduced at least one fixed rate since the start of June, even as uncertainty remains over whether the RBA has finished tightening.
For borrowers, the key message is not that fixed loans have suddenly become cheap. In many cases, rates still start with a six, and that can be difficult to accept for households already absorbing higher grocery, insurance and utility costs. However, the cuts do suggest lenders are competing more actively for borrowers who value repayment certainty, particularly over shorter fixed terms.
The decision to fix should be based on household cash flow, not simply a prediction about the RBA. A fixed rate can help protect monthly repayments from further increases, but it can also limit flexibility. Break costs, restrictions on extra repayments, redraw limitations and offset account access should all be reviewed before signing. Borrowers who may sell, refinance, renovate or make large additional repayments should be especially cautious.
It is also worth comparing fixed offers against variable and split-loan options. Some smaller lenders remain more aggressive than the major banks, and refinancing may still deliver a better outcome than accepting a headline fixed-rate cut from an existing lender. Before making a move, borrowers should be comparing options across rates, fees, features and long-term flexibility.
A practical next step is to stress test repayments under several scenarios: another rate rise, no change, and eventual cuts from 2027. Modelling repayments can help show whether certainty is worth the trade-off. In a market where economists and banks remain divided, the best mortgage strategy is the one that still works if the forecast is wrong.
