Predicting RBA Rate Path in 2026: Managing Interest Rate Risk with Fixed Rate Splitting and Offset Accounts

How Economists View the 2026 RBA Rate Path

Economists have offered a range of forecasts for the Reserve Bank of Australia’s cash rate through 2026. While there is no single consensus, most projections sit within a band that assumes gradual easing from current levels. Some see the cash rate falling to around 3.6 per cent by the end of next year, while others anticipate a more cautious path, with reductions occurring later and in smaller increments. The outlook depends heavily on inflation data, wages growth, and the health of the domestic labour market.

Uncertainty about the global economy also influences the RBA’s likely approach. A slower-than-expected recovery in major trading partners, or renewed supply-side pressures, could delay or accelerate the timing of rate moves. Economists stress that the path is not predetermined, and that the RBA will remain data-dependent, adjusting its stance as new information arrives.

Strategies Borrowers May Consider

For borrowers seeking to manage interest rate risk in this environment, two strategies frequently come up: splitting a home loan between fixed and variable rates, and using an offset account.

Fixed rate splitting involves dividing a loan into multiple portions, each with its own rate structure. This can provide a measure of certainty for part of the debt, while retaining some flexibility for the remainder. Lenders may offer different fixed-rate terms, allowing borrowers to stagger the periods they come due, which can reduce the impact of a single re-pricing event.

Offset accounts are transaction accounts linked to the home loan. The balance in the offset reduces the principal on which interest is calculated, potentially lowering the interest charged each month. Offset accounts typically offer full access to funds, and many are 100 per cent offset, meaning the entire balance offsets the loan. Some lenders restrict offset features to variable-rate loans, so borrowers should confirm whether an offset is available if they also hold a fixed-rate portion.

Considerations for Fixed Rate Splitting

When implementing a split, borrowers should weigh the trade-off between rate certainty and flexibility. A fully fixed loan removes exposure to rate rises, but also removes the benefit of any rate cuts, and often carries break costs if the borrower repays early or changes the loan during the fixed period. A split can help balance these factors.

Experts suggest that a common approach is to fix a portion of the loan, such as one-third or one-half, for a term that matches the borrower’s expectations about rate movements, while keeping the remainder variable to benefit from potential future cuts. The optimal split varies by individual financial circumstances, risk tolerance, and the borrower’s time horizon.

Borrowers should also review the terms of any fixed-rate portion, including whether the rate includes a comparison rate, and what fees or charges apply if the fixed term is broken. Comparing loans from multiple lenders can help identify competitive rates and flexible features.

How to Approach Your Decision

Before making any changes, borrowers should model their likely repayments under different rate scenarios. This can help clarify how much financial buffer they have if rates rise, and how much they would save if rates fall. It is also worth considering the loan’s LVR (loan-to-value ratio), as this can affect the rates offered by lenders.

Given the range of economic forecasts, there is no single right answer. Some borrowers may prefer the certainty of a fixed rate for a few years, while others may accept variable-rate risk for the chance to benefit from cuts. A home loan specialist or mortgage broker can help assess individual circumstances, but the ultimate decision should be based on personal finances and risk appetite.

Frequently Asked Questions

Can I have an offset account with a fixed-rate loan?

Offset accounts are not always available on fixed-rate loans. Some lenders offer offset features on variable-rate loans only. Check with your lender before assuming an offset is attached to a fixed portion.

What are the risks of fixing a portion of my loan?

If the RBA cuts rates, the fixed portion will not benefit, and you may face break costs if you exit the fixed term early. Also, fixed rates may be higher than the corresponding variable rate at the time of fix.

Is splitting my loan a common strategy?

Yes, splitting between fixed and variable is a well-known way to manage interest rate risk, though it is not suitable for everyone. It can provide a balance of certainty and flexibility.
