Fixed vs Variable in a Hiking Cycle: The 2026 Decision Framework

Key takeaways

• Fixed rates are priced off swap markets, so they already embed expected rate moves — you are rarely getting a bargain.
• Fixed loans usually restrict extra repayments and offset accounts, and exiting early can trigger break costs.
• A split loan lets you fix part of the debt and keep offset and flexibility on the rest.
• Borrowers rolling off 2023 fixed loans in 2026 are facing the second fixed-rate cliff, often a jump of several hundred dollars a month.

Why is fixing not a bet you can win?

Lenders fund fixed-rate loans by borrowing at fixed rates in wholesale markets. The swap rate for a given term already reflects what professional participants collectively expect the cash rate to do over that term. Your lender adds a margin for cost and risk.

So if the market expects rates to rise, fixed rates are already higher than variable ones. You are not buying a forecast — you are buying insurance, and the premium is the gap between the fixed and variable rate.

What do you give up?

Fixed loans in Australia typically restrict:

• Extra repayments, commonly capped between $10,000 and $30,000 a year.
• Offset accounts, often unavailable or only partially effective on the fixed portion.
• Exit flexibility. Break costs are not a penalty fee — they recover the lender's loss if wholesale rates fall after you fix, and on a large loan they can run into tens of thousands.

If there is any realistic chance you will sell, refinance or receive a lump sum during the fixed term, those restrictions matter more than the rate difference.

When does fixing genuinely make sense?

Certainty has real value in specific situations:

• Your budget has no capacity to absorb another increase, and you would rather lock in a known number than gamble.
• Household income is about to fall predictably — parental leave, a planned career change, retirement.
• You are at the edge of serviceability and a further rise would push you into hardship.

A split is often the honest answer: fix the portion that must be certain, keep the rest variable with an offset. There is no rule requiring a 50/50 split — match the fixed portion to the part of the repayment you genuinely cannot flex.

Frequently asked questions

What happens when my fixed term ends?

The loan reverts to the lender's variable rate, which is frequently higher than the rate offered to new customers. Diarise the revert date about eight weeks in advance and negotiate or refinance before it hits, rather than after.

Can I make extra repayments on a fixed loan?

Usually up to an annual cap set by the lender. Exceeding it can trigger a break cost, so check your contract before making a large lump-sum payment.

Is a split loan more expensive?

Not usually in fees, though some lenders treat each split as a separate loan account with its own charges. The real trade-off is complexity: two balances, two rates and, on the fixed portion, the usual restrictions.
