Should I fix my home loan interest rate in 2026?

It is one of the most common questions borrowers ask, and there is no universal right answer, only the answer that suits your situation. This is general information rather than advice, so the aim here is to lay out the real trade offs clearly so you can weigh them for yourself.

What fixing actually does

Fixing locks your interest rate for a set term, commonly one to five years. Your repayment stays the same for that term regardless of what the RBA or your lender does. At the end of the term the loan generally reverts to a variable rate unless you fix again.

The case for fixing

The main argument for fixing is certainty. If a further rate rise would genuinely stress your budget, locking your rate removes that risk for the fixed term and makes budgeting predictable. For borrowers who value peace of mind, or who are stretched, that certainty can be worth more than the chance of a lower variable rate.

The case against fixing

Fixing usually costs you flexibility. Fixed loans often limit or prevent extra repayments, generally do not offer a full offset account, and can charge break costs if you exit or refinance during the term. You also miss out if variable rates fall below your fixed rate. For borrowers who want to pay extra or keep their options open, that loss of flexibility matters.

The 2026 backdrop

Context matters. As at 2026 the RBA raised the cash rate to 4.35 per cent after a period of cuts, and the outlook is uncertain, with economists divided on the next move. That uncertainty is exactly why the fix versus variable question is hard right now, because neither direction is clear.

Fixed rates already price in expectations

It is worth knowing that fixed rates are not a free bet. Lenders set fixed rates based on where they expect rates to go, so today fixed rates already reflect market expectations of future moves. Fixing is buying certainty, not outsmarting the market.

A split loan as a middle ground

You do not have to choose all or nothing. A split loan lets you fix one portion and keep the other variable, so you get some certainty and some flexibility. Many borrowers who cannot decide use a split as a sensible compromise.

It really does depend on you

The right choice turns on your own circumstances: how sensitive your budget is to a rate rise, whether you plan to sell or repay early, and whether you want features like an offset. There is no setting that is right for everyone, which is why a blanket recommendation is not possible.

This is general information, so get advice

Because the decision depends on your situation and the rate outlook is uncertain, it is worth talking it through rather than acting on a rule of thumb. A broker can walk you through the trade offs for your circumstances. Nothing here is a recommendation to fix or not.
